The present application claims the priority of the Chinese Patent Application No.
200810161803.X filed on September 22, 2008, entitled "Method, System and Apparatus for a
Public Emergency Broadcast System Alarm", the entire contents thereof are incorporated
herein by reference.
FIELD OF THE INVENTION
The present disclosure relates to the technical field of communications, and more
particularly to a method, system and apparatus for a public emergency broadcast system
alarm.
BACKGROUND OF THE INVENTION
An Earthquake and Tsunami Warning System (ETWS) is a public emergency
broadcast system which sends a warning to user terminals through a Third Generation
Partnership Project (3GPP) access network, which includes GSM DEGE Radio Access
Network (GERAN), Universal Terrestrial Radio Access Network (UTRAN), and Evolved
UTRAN (E-UTRAN), etc. When the ETWS detects an earthquake event or a tsunami event,
its warning notification shall be successfully distributed to the terminals in the area
influenced by earthquake or tsunami as soon as possible so as to save lives.
In the prior art, a Primary Notification message of the ETWS is sent to the user
terminal, so that the user terminal may receive an alarm message. The Primary Notification
message is dedicated for the ETSW system and for notifying users of the most emergent
event. A complete Primary Notification message of the ETWS may need to be segmented and
need a plurality of Paging Request Type 1 messages to carry it. At this time, a Page Mode
information element value of the Paging Request Type 1 message must be set to be "same as
before", and the terminal supporting the ETWS capability will enter the non-Discontinuous
Reception (non-DRX) mode when it reads out that "Page Mode" is equal to "same as before",
so as to receive the paging messages for all paging groups. At this lime, all paging messages
are configured to continuously broadcast the Primary Notification message, so that user
terminals may receive a full warning message as soon as possible.
During implementation of the present disclosure, the inventor finds that the prior art
has at least the following problems.
When the "page mode" information element is set to be "same as before", the
terminal enters the non-DRX mode. However, the fact that the "page mode" information
element is equal to "same as before" does not necessarily indicate it is the Primary
Notification message that is sent, while at this time the terminal is still entering the non-DRX
mode, which influences the use of the terminal. In the prior art, the fact that the terminal has
entered the non-DRX mode does not indicate a complete Primary Notification message may
be received. That is, a mechanism for receiving a complete Primary Notification message is
not provided. Even if the terminal enters the non-DRX mode and receives one ETWS
Primary Notification message completely, there is still no explicit mechanism for exiting the
non-DRX mode. That is, the terminal may not exit the non-DRX mode in time. The terminal
remains in the non-DRX mode for a very long time, which seriously reduces the service life
of a terminal battery.

DETAILED DESCRIPTION OF THE EMBODIMENTS
The technical solution according to the embodiments of the present disclosure is
described clearly below with reference to the drawings in the embodiment of the present
disclosure. Obviously, the described embodiments are only some exemplary embodiments of
the present disclosure, not all the embodiments. All the other embodiments obtained by
persons skilled in the art based on the embodiments of the present disclosure without creative
effort fall within the protection scope of the present disclosure.
The first embodiment of the present disclosure provides a method for a public
emergency broadcast system alarm, which is described below with reference to Fig. 1. The
method includes the following blocks.
In block SI01, a paging request message is received.
In block SI02, when the paging request message includes a partial message or an
indication of a primary notification message, a terminal determines to start entering the
non-DRX mode so as to continuously receive the remaining part of the primary notification
message.
In block SI03, the terminal exits, when the primary notification message has been
received completely, the non-DRX mode. Optionally the terminal starts a timer when starting
entering the non-DRX mode and exits the non-DRX mode when the timer expires.
As can be seen from the above description, according to the embodiments of the
present disclosure, the terminal enters the non-DRX mode only when the received paging
request message includes a partial message or an indication of a primary notification message,
and may exit the non-DRX mode when necessary.
The second embodiment of the present disclosure provides a method for a public
emergency broadcast system alarm, which is described below with reference to Fig.2. The
method includes the following blocks.
In block S201, a Cell Broadcast Centre (CBC) sends a Primary Notification request of
the public emergency broadcast system to a Base Station Subsystem (BSS).
For example, an alarm message of the public emergency broadcast system at least
includes an alarm message of the ETWS system. In all the embodiments of the present
disclosure, the public emergency broadcast system is the ETWS system. The apparatus for
sending the Primary Notification request of the ETWS is not limited to CBC, but may include
any server and/or network unit configured to send the ETWS Primary Notification request.
In block S202, when the BSS receives the Primary Notification request of the ETWS,
the BSS adds the ETWS Primary Notification into a Paging Request Type 1 message with or
without segmentation, and continuously sends the Paging Request Type 1 message to the
terminal on the Common Control Channel (CCCH) in a cell influenced by the BSS, for
example the Paging Request Type 1 message is sent on the Paging Channel (PCH). The
Paging Request Type 1 message includes three information elements which are "Page Mode",
"Mobile Identity 1" and "PI Rest Octets". The cells influenced by BSS may be set by the
CBC service center. The process of continuously sending the Paging Request Type 1 message
on the CCCH is embodied as to send the Paging Request Type 1 message through the Paging
Channel (PCH) on the CCCH.
For example, the BSS sets the "Page Mode" information clement in the Paging
Request Type 1 message, which is continuously sent on the CCCH in the influenced cell, to
be "same as before". That is, the value of the Page Mode Information Element (IE)
continuously set on the CCCH is "same as before". With reference to the simplified
schematic diagram illustrating the setting of the Paging Request Type 1 message by the BSS
as shown in Fig.3, the BSS further sets the "Mobile Identity 1" information element in the
Paging Request Type 1 message to be "no identity", and sets the "PI Rest octets" information
element in the Paging Request Type 1 message to include relevant information of the ETWS
"Primary Notification". Through a particular instruction or command, the "PI Rest Octets"
information element includes the relevant information or the indication of the ETWS
"Primary Notification". That is, the Primary Notification segment is included in the "PI Rest
Octets" information element.
In order to avoid chaos cause by the reception of unauthorized information, the
Primary Notification message may include authentication information, which may result in
that data amount of the data size of the Primary Notification message may exceed the
expected upper limit. As a result, the Primary Notification message needs to be segmented
and then sent. For example, in terms of the expectation provided by the GERAN, the largest
length of the Primary Notification message is 51 bytes, where one byte represents the type of
the warning, the other 50 bytes include a digital signature. However, one paging message
may carry ten or more bytes only, and the Primary Notification message needs to be
segmented into four or five segments. However, each segment of the Primary Notification
message is respectively included in one Paging Request Type 1 message, that is, the Primary
Notification message needs to be segmented and sent in a plurality of Paging Request Type 1
messages.
In block S203, the terminal receives the Paging Request Type 1 message sent by the
BSS, that is, the terminal receives the alarm message of the ETWS. The terminal judges
whether the Paging Request Type 1 message includes the Primary Notification message.
When the received message includes one part of the Primary Notification message, the
terminal enters the non-DRX mode and starts a timer at the same time; meanwhile, when the
received message includes one complete Primary Notification message, the terminal remains
in its reception mode, that is, the terminal does not necessarily enter the non-DRX mode.
Specifically, the Primary Notification message is included in the "PI Rest Octets"
information element in the form of segments, so the terminal enters the non-DRX mode when
the Paging Request Type 1 message received by the terminal includes a part of the Primary
Notification message. That is, when the "PI Rest Octets" information element is set to
include the "Primary Notification" of the ETWS, the terminal enters the non-DRX mode. In
addition, the condition for the terminal to enter the non-DRX mode may also be as follows: 1)
the "PI Rest Octets" information element is set to include the relevant information or the
indication of the "Primary Notification" of the ETWS, and the "Page Mode" information
element is set to be "same as before" at the same time; or 2) the "PI Rest Octets" information
element is set to include the relevant information or the indication of the "Primary
Notification" of the ETWS, the "Page Mode" information element is set to be "same as
before", and the "Mobile Identity 1" information element is set to be "no identity" at the
same time. In addition, the condition for the terminal to enter the non-DRX mode may also be
as follows: 1) the PI Rest Octets information element is set to be the information element
including the Primary Notification message of the ETWS, and the Page Mode information
element is set to be "paging reorganization"; or 2) the PI Rest Octets information element is
set to be the information element including the Primary Notification message of the ETWS,
the Page Mode information element is set to be "paging reorganization", and the Mobile
Identity 1 information element is set to be "no identity".
After the terminal enters the non-DRX mode, the terminal does not deal with a
network instruction if the terminal receives the network instruction which instructs the
terminal to exit the non-DRX mode and/or enter the DRX mode, so as to ensure that the
terminal may receive the complete Primary Notification message as soon as possible. In
addition, after the terminal enters the non-DRX mode, the terminal remains in the non-DRX
mode until the complete Primary Notification message has been received or until the timer
exceeds the preset time limit, so as to ensure that the terminal may exit the non-DRX mode.
The timer is started when the terminal enters the non-DRX mode, and the time limit of the
timer may be set according to the experience or history, for example, 10s.
In order to enable the terminal to receive the content of each segment of the Primary
Notification message in any order, it shall be ensured that the size of each segment of the
Primary Notification message and the content in each segment of the Primary Notification
message are consistent. Moreover, the Paging Request Type 1 message may include the
segments of Primary Notification only, rather than any other paging. When there is the
Primary Notification message to be sent, the transmission priority of the warning message of
the ETWS is higher than that of a normal call or paging. Meanwhile, during the warning of
ETWS, other calls may still be initiated, for example, the priority call from a security
department.
It is obvious, in this embodiment of the present disclosure, the terminal enters the
non-DRX mode only when the PI Rest Octets information element in the received Paging
Request Type 1 message includes the Primary Notification message. Meanwhile, the terminal
has the mechanism for exiting the non-DRX mode, and may exit the non-DRX mode when
necessary, for example, when the complete Primary Notification message has been received
or the timer expires.
The third embodiment of the present disclosure provides a system for a public
emergency broadcast system alarm, which is described below with reference to Fig.4. The
system includes:
a terminal 42, configured to: receive a paging request message sent by a base
station subsystem BSS 41; determine, when the paging request message includes a partial
message or an indication of a primary notification message, to start entering the non-DRX
mode so as to continuously receive the remaining part of the primary notification message;
and exit, when the primary notification message has been completely received, the non-DRX
mode, or start a timer when starting entering the non-DRX mode and exit the non-DRX mode
when the timer expires.
Specifically, the paging request message includes the Paging Request Type 1 message.
The Paging Request Type 1 message includes three information elements: PI Rest Octets,
Page Mode and Mobile Identity 1. The content of PI Rest Octets includes a part of the
Primary Notification message, and the BSS41 sets the PI Rest Octets information element to
be the information element including the Primary Notification message.
As can be seen from the above description, according to the embodiment of the
present disclosure, the terminal enters the non-DRX mode only when the PI Rest Octets
information element in the received Paging Request Type 1 message includes a part of the
Primary Notification message. Meanwhile, the terminal has the mechanism for exiting the
non-DRX mode, and may exit the non-DRX mode when necessary, for example, when the
complete Primary Notification message has been received or the timer expires.
The fourth embodiment of the present disclosure provides an apparatus for a public
emergency broadcast system alarm, where the apparatus is a terminal, which is described
below with reference to Fig.5. The apparatus includes:
a receiving module 51, configured to receive a paging request message;
a starting module 52, configured to determine, when the paging request message
received by the receiving module 51 includes a partial message or an indication of a primary
notification message, to start entering the non-DRX mode so as to continuously receive a
remaining part of the primary notification message; and
an exiting module 53, configured to: exit, when the primary notification message
has been completely received by the receiving module 51, the non-DRX mode started by the
starting module 52; or start a timer when the starting module 52 starts entering the non-DRX
mode and exit the non-DRX mode started by the starting module 52 when the timer expires.
The apparatus for a public emergency broadcast system alarm according to another
embodiment of the present disclosure may include a remaining module 54, configured to:
receive, before the exiting module 53 exits the non-DRX mode, an instruction of entering the
discontinuous reception mode or exiting the non-DRX mode; and omit the instruction of
entering the discontinuous reception mode or exiting the non-DRX mode, and remain in the
non-DRX mode.
As can be seen from the above description, in the embodiment of the present
disclosure, the terminal enters the non-DRX mode only when the PI Rest Octets information
element in the received Paging Request Type 1 message includes a part of the Primary
Notification message. Meanwhile, the terminal has the mechanism for exiting the non-DRX
mode, and may exit the non-DRX mode when necessary, for example, when the complete
Primary Notification message has been received or the timer expires.
With the description of the above embodiments, persons skilled in the art may clearly
appreciate that the present disclosure may be realized by means of a hardware or by means of
a software plus a necessary common hardware platform. Based on the understanding, the
technical solutions of the embodiments of the present disclosure may be embodied in the
