Descri pition
Method and mobile communication appliance for selecting a
transmission path
The invention relates to a method for a mobile communication
appliance in accordance with the precharacterizing part of
patent claim 1 and to a communication terminal for wirelessly
accossing a plurality of transmission paths in accordance with
the procha racterizing part of patent claim 10.
There are frequently various radio-based voice networks and
data networks available for mobile communication links. In this
context, the radio-based voice networks, that is to say GSM
networks, DECT networks and UMTS networks, for example, can
also be used for data transmission, as can, conversely, radio-
based data networks, that is to say WLAN networks, WiMax
networks and Bluetooth networks, for example, can also be used
for voice transmission (e.g. VoIP - Voice Over Internet
Prolocol).
While, in many cases, the same requirement (voice transmission,
data transmission etc.) can thus be met in the same or a
similar quality using different types of mobile networks and
hence using different transmission paths, these transmission
paths differ, however, in terms of the costs respectively
related to their use, in terms of their bandwidth, the delay
times, there reliability (connections being cut off) etc .
To be able to take hold in a specific situation between
different transmission paths and their respective related
advantages and drawbacks as required, what are known as
multimodal mobile communication appliances are frequently used.
By way of example, these are PCs which have both Bluetooth and

WLAN transmission devices, or else mobile radios (telephones)
which selectively support connections


based on t;he GSM standard, the UMTS standard and/or the DECT
standard. Before setting up a communication link, for example a
telephone call, a user of such a communication appliance can
thus select the transmission path which is to be used for the
next communication link. Alternatively, it is also possible to
permanently preset different transmission paths (GSM, GPRS,
DECT) for different communication services (voice, fax, SMS,
Internet. WWW, etc.).
Frequently, a transmission path is also selected automatically
by the communication appliances by checking the availability of
the various transmission paths at the time at which a
communication link is initiated. To this end, by way of
example, a field strength measurement is used to check whether
the various base stations of different transmission paths (for
example DECT, WLAN) can be received. If it is available, the
(inexpensive) WLAN network is then selected, for example, using
a priority list, whereas a GSM mobile radio Jink is selected as
the transmission path if a WLAN network or a DECT cell is not
available .
The document US 2004/0242240 A1 Lin "Location Assisted
Communications Mode Switching" discloses a method in which
multimodal terminals take their geographical position as a
basis for reading a preferred communication mode from a table
and, if the terminal is in another communication mode, changing
to this selected communication mode. This process is repeated
aL regular intervals of time .
The document US 5,752., 164 Jones "Autonomous Remote Measurement
Unit for Personal Communications Service System" discloses a
method for a communication network, in which different
frequency channels of a wide frequency band can be used
alternately for communication. In this case, the area in which
the communication system is used is divided into a number of

honeycomb-like regions, with interference on or use of the
individual radio channels being measured for each region by
means of measuring devices provided in each honeycomb and being
stored in a central database. These measurements are preferably
taken repeatedly and used to maintain the data base formed
thereby. When a mobile terminal is used, position-finding is
performed for this terminal, and access to the database is used
to establish which radio channels are free or have little
interference, so that a free or low-interference radio channel
can be used for communication.
The document US 5,974,328 Lee et al. "Rapid System Access and
Registration in Mobile Phone Systems" likewise discloses a
database-based method for location-dependent configuration of a
mobile terminal. In this case, a mobile terminal is supplied
with respective optimized registration parameters for
registration in a mobile radio network from a database on the
basis of location.
In the case of the known methods and devices for selecting one
of a plurality of transmission paths, it is found to be
d:i sadvan tageous that the selected transmission path in many
cases docs not assure the required transmission quality, and/or
al though a high-quality transmission path is selected it is in
many cases unnecessarily expensive. It is therefore an object
of the present invention to improve the selection of a
respective transmission path used when mobile communication
appliance sare used.
The object is achieved by a method in accordance with patent
claim 1 and by a communication appliance in accordance with
patent claim 10 .

The object is achieved by using a method for selecting a
transmission path for a communication link. from a mobile
communication appliance, where the mobile communication
appliance can select at least two transmission paths. In this
context, a first step involves a statement about the location
of the communication appliance being ascertained,
a second step involves the ascertained statement being used to
access a database for transmission paths,
a third step involves at least one entry in the database being
used to determine a preferred transmission path, and
a fourth step involves the preferred transmission path being
selected and being used for a communication link. The use of
this method allows location-dependent selection of the
transmission path, with the entry in the database being able to
be used to prescribe various preferred transmission paths for
various locations. To this end, statistical statements about
previous uses of at least one of the transmission paths are
used for the database, where at least one correlation between a
statement about the location used during a previous use and a
statement, picked up during the previous use, about the quality
of the transmission path used is stored and used to select the
transmission path. An "empirical database" of this kind means
that if is possible to dispense with the use of a particular
transmission path at a location at which this transmission path
is known (from experience) to have frequent interference.
The object is also achieved by proposing a communication
appliance for wirelessly accessing a plurality of transmission
paths, one of the plurality of transmission paths being able to
be selected for a communication link. In this context, the
communication appliance is equipped with a position-finding
device for ascertaining a statement about a geographical
position of the communication appliance, and the communication
appliance is equipped for accessing a database, the database
having at least one entry with a statement, based on empirical

values from past, communication links, about a quality which can
be expected for one of the transmission paths with at least one
associated statement about a location. In addition, the
communication appliance is equipped with a selection device for
one of the plurality of transmission paths, the selection
device being in a form such that the statement; about the
location and the at least one database entry are used to select
and use a transmission path which corresponds to a minimum
qualify requirement. Such a communication appliance is always
used to select that transmission path which, empirically,

meets a proscribed minimum quality requirement for the location
of the communication appliance. This means that it is always
possible to select a transmission path which, although it is
powerful enough, permits the most inexpensive and/or power-saving mode of operation possible for the communication
appliance. To this end, a user advantageously defines various
criteria as aims, for example cost criteria, energy criteria,
time criteria (duration of connection setup, transmission time
for a particular volume of data, delay times etc.) .
Advantageous refinements of the inventive method are specified
in patent claims 2 to 9. The features and advantages described
therein also apply mutatis mutandis to the inventive
communication appliance.
In this case, the database may be stored in the communication
appliance itself, which means that access to the database is
particularly rapid and simple, and it is a simple matter to
prevent manipulation of the database by third parties. On the
other hand, a database which is available centrally in a
communication network may also be used for this purpose, which
means that a communication appliance can also use the empirical
values and rules (routing rules) from other communication
appliances. Finally, the parallel use of both a local and a
central database is also advantageous in many cases, because it
firstly allows redundancy requirements to be met, and secondly

allows "one's own" entries to be used preferably, in order to
be able to resort to the centrally stored entries if such
entries "of one's own" are not present.
The structure of radio networks and their locally differing
reception circumstances and also the time-variant utilization
level of transmission paths can easily be taken into account by
virtue of use of the selected transmission path being followed
by a qualify registered in the process for the transmission
path and the staternent about the location being used by the
communication appliance for a fresh entry in the database
and/or for correcting an existing entry in the database. In
this context, the quality stored and taken into account may
advantageously be a combination of individual criteria, e.g.
costs, bandwidths, reliabilities (for example number of
connect ions cut. off per unit time), delay times (for example in
the case of VolP links) etc.
The data obtained through the continuous and automatic "care"
of the entries in the database may advantageously also be used
for optimizing a radio network to which an associated
transmission path belongs. It is therefore possible in many
cases to dispense with the separate measurement of radio areas
and nevertheless to obtain a constantly up-to-date overview of
radio ranges, "radio holes", field strength distributions or
the like. In this case, it is also possible for a central
location (for example a system administrator) to make changes
in the data records in the database such that future selection
decisions are influenced. This makes it possible to control the
utilization level of individual connecting paths and to avoid
bottle necks .
If a time statement about the time and/or the time of day
and/or a day-of-week statement is used to select the
transmission path, the database providing statistical
statements about the quality of at least one transmission path

for a particular time and/or Lime of day and/or day of the
week,


iL is also possible to take account of changes on the
transmission paths which are recurrent on the basis of time. By-
way of example, this involves taking account of cases in which
particular transmission paths (for example a company WLAN) have
a high utilization level at particular times of day (for
example during normal business hours) and therefore provide
reduced bandwidth .
Manual input of location information into a communication
appliance is avoided if the statement about the location of the
communication appliance is ascertained using a
satellite-assisted position-finding system (e.g. "GPS") and/or
a method for position-finding using received terrestrial radio
base stations (field strength and/or propagation-time
measurements) .
The inventive method can be used particularly flexibly and
often universally if a WLAN radio network, a GSM mobile radio
network and/or a UMTS voice data radio network is selected for
the transmission path. Accessing these widespread transmission
paths means that there is a high likelihood of one or even more
transmission paths always being available for selection.
Exemplary embodiments of the inventive method are explained
below with reference to the drawing. They are simultaneously
used to explain a communication appliance based on the
invention .
In this context, the single figure uses a schematic
illustration to show a control device ("Gall Processing"), a
selection device and access units ("Connectors") for a
communication appliance.
The figure shows a schematic illustration of components of a
mobile communication appliance. In this case, the mobile

communication appliance is what is known as a "smart phone",
that is to say an appliance in which the functions of a mobile

computer ("PDA" - Personal Digital Assistant) and the functions
of a mobile radio (mobile telephone) arc combined with one
another. The communication appliance is in multimodal form,
that is to say has access units K (connectors) for various
radio networks,, in this case GSM, WLAN, Bluetooth, WiMax, UMTS,
etc. in addition, the communication appliance also has access
units K for wired communication; for this, the figure shows an
Ethernet access unit by way of example.
The text below-unless a different description is
given - simply assumes that each access unit K is associated
with precisely one transmission method (GSM, internet Protocol,
ISDN...), which means that the access units K in the figure
simultaneously represent transmission methods. In this case, a
transmission method can be used to access a plurality of
transmission paths; by way of example, a single GSM connector
can be used to access a plurality of mobile radio networks
(even with different network operators) and a single LAN port
can be used to access different VolP gateways/gatekeepers or
the like. For reasons of further simplification, it is
subsequently also assumed that each access unit K has not only
precisely one associated transmission method but also precisely
one associated transmission path, which means that the
reference symbols for the access units K simultaneously denote
transmission methods and finally transmission paths.
The communication appliance also has a control device CP ("Call
Processing") which the applications (not shown) on the
communication appliance use as a control device and as an
interface tor external communication. In the present exemplary
embodiment, the control device CP is a call processing unit for
switching voice links, as is known from circuit-switched
communication installations ("PBX"). Generally, however, it is
also possible to use any other control device, for example,
VolP gatekeepers, e-mail distribution devices etc. or else
multifunctional control devices for

switching different data types and communication streams.
Whereas "conventional" monomodal 'communication appliances
regularly involve the control device CP communicating only with
a single access unit K, the control device CP in the present
exemplary embodiment uses a selection device At; to access
different access units K. To this end, the control device CP is
in a form such that it sets up a communication 1ink or a data
channel to the selection device AE by transmitting not only a
communication address (telephone number, IP address or the
like) but also a statement about a quality requirement.
In the present exemplary embodiment, the statement about the
quality requirement comprises a plurality of criteria. First,
the control device CP uses internal signaling to notify the
selection device All of a type (type statement) for the next
communication link on the basis of the application which
requires the communication Link (or data channel or the like).
That is to say that for voice links, for example, there is
different signaling than for the transmission of an e-mail,
message or an SMS message. In the case data applications
(internet access or the like), it is also possible for a
desired minimum bandwidth (for example 128 kbit/s) to be
requested which is ascertained automatically or is input by a
user.
From the point of view of the control device CP, the selection
device AM works Like a - single - access unit K. The selection
de vice. All therefore "conceals" the peculiarities of the
individual access units K which are actually present. It is
therefore also possible and advantageous for only an abstract
descriptor (e.g. the name) for the desired call party to be
transmitted from the control, device CP to the selection device
AE instead of a specific communication address (telephone
number, IP address) . The subsequently

selected - transmission path and transmission method (and hence
the access unit K to be used) are then used to retrieve the
"appropriate" communication address from an address directory
(preferably likewise stored in the database DB). It is
therefore possible to change the transmission path and
transmission method even during an ongoing call, for example
from a VoIP link (with an IP address as communication address)
to an ISDN link (with a "conventional" telephone number as
communication address) .
The selection device AE and the control device CP access a
common database DB (empirical database), this database DB being
integrated in the communication appliance DB in the present
exemplary embodiment. As an alternative or in addition, it is
naturally possible to use a network-assisted, central database
DB for use by a plurality of communication appliances.
In another a1ternative refinement, it is a1so possible for
different communication appliances to reciprocally access the
databases on other communication appliances and to use the
entries they contain for selecting an access unit K and hence a
particular transmission path.
The text below describes the setup of a communication link by a
communication appliance having the technical devices described
above. To this end, the communication appliance has a technical
device, a position-finding device which assures at least coarse
geographical position-finding for the communication appliance.
In the prescnt exemplary embodiment, this is done by detecting
the identification numbers ("base station IDs") of the various
radio cells in whose reception area the communication appliance
is currently active. The identification numbers and the
reception field strengths of the respective radio cells are
reported to the selection device AE by the various

access units K at regular intervals of time. From the
statements from the various access units K, the selection
device AE creates an up-to-date location profile.
Alternatively, position-finding is also possible using a
satellite-assisted system, for example GPS. Finally, in cases
in which up-to-date position-finding is not possible, a
"default, location" can be prescribed for different times of day
(e.g. week days between 12.00 and 16.00 hours: in the office
having the coordinates xy).
Preferably - as described below - a routing decision is made
primarily on the basis of the current Location and secondarily
on the basis of other requirements. Alternatively, a
distinction can also be drawn primarily on the basis of the
type of user or use (private/business etc.), or cost or quality
features are considered first. These settings can be influenced
either by users or by an administrator, according to an
authorization model.
It is subsequently assumed that a communication application is
to be used to set up a video telephony link. To this end, the
application with the task of doing so sends the control device
CP a request message which transmits not only the type of
communication link required (in this case: "real-time stream")
but also a desired bandwidth (in this case: 192 kbit/s full
duplex) and an associated qualify class (in this case: best
qualify no connections being cut off if possible and little
delay). On the basis of the requirements given, the selection
device All decides that only some of the available transmission
paths and hence certain access units K are suitable for the
communication link required, namely Ethernet, WLAN, WiMax and
UMTS. To make this decision, the selection device AF, loads a
data record, describing the basic performance of the relevant
access unit K and of the transmission path linked to it at the
current location,

from the database DB at least once for each available access
unit K.
The selection device AE now ascertains tho current availability
of the previously selected access units K and hence of the
transmission paths selected with them. This establishes that
the access unit "Ethernet" is currently not available, that is
to say that no Ethernet network port is connected or active.
Of the remaining access units K, the two WLAN access units
(2.4 Gil/.; 5 GHz), the WiMax transmission path and the UMTS
radio module are suitable for meeting the requirements
transmitted with the request message.
The selection device AE therefore accesses the database DB
again and loads a respective cost table for the suitable access
units K in order to select, the cheapest, transmission path and
hence the most suited access unit K according to the situation.
In this context, it is optionally also possible to select the
cheapest "provider" if an access unit K and hence a
transmission method have a plurality of providers (service
providers) and hence a plurality of transmission paths
availiable (for example a p1urality of GSM networks are
available).
When the selection device AE has decided to use a particular
access unit K (in this case the cheap 2.4 GHz WLAN is used),
the desired connection is set up and the selection device
awards the control device CP what, is known as a "quality
monitoring order". On the basis of the "quality monitoring
order", the control device CP transmits a quality message,
which is known as "feedback", which is also known as a "QoS
(Quality of Service) data collection (QDC)", when the
communication link previously set up has been terminated. With
this quality message, the selection device AE

receives statements about any connections which may have been
cut off, the average, minimum and maximum transmission
bandwidth and, if available, statements about the costs
incurred. Together with the already available statement about
the current location, the selection device AE uses these data
to update the database DB, with a new data record first of all
being created. Already available empirical values about the
location and about the transmission path used may alternatively
or additionally involve an existing data record being updated.
When existing data records are updated, a filter algorithm
ensures that "outliers", for example, a single instance of a
connection being cut off, do not result in the affected
transmission path no longer being selected Long term. At the
same time, the filter algorithm ensures that "more recent"
qualify statements are given a higher weighting than statements
from longer ago; thi s relates particularly also to cost
statements, because providers are frequently changing the costs
for their services. Slatislical methods can thus be used to
compile a plurality of data records.
In this case, the database DB has an optional interface to a
network management system (not shown). Such network management
systems allow an overview to be obtained about data
infrastructures and in so doing are used for error searches and
network planning. The QoS statements "automatically"
ascertained when communication links are used and hence when
transmission paths are used are - as described - used for
constantly updating the database DB, so that the information in
the database DB can be used as a replacement for complex
separate network measurements.
Particularly in the case of configurations in which both local
and central databases are used, regular alignment of the local
databases and the central database allows a central stock of
data to be set up and maintained which, by means of targeted
evaluation, identifies infrastructure

defects. Changes to the entries to the databases, for example
by an administrator, then allow the "behavior" of communication
appliances to be influenced, for example so that connecting
paths with a low utilization level are preferred. The alignment
described means that an entry at a central location, that is to
say in a central database, is then sufficient even when local
databases are used.
