Description
Technical Field
The present invention relates to mobile communication technologies, and in particular, to a method and an apparatus for processing an application layer paging message.
Background
The 3GPP Mission Critical Push To Talk (MCPTT) standard protocol 23.379 defines a procedure for sending Application layer paging (Application paging) using an MBMS multicast channel. The message is used to inform the terminal that it needs to enter the connected state. If the received terminal is in an RRC idle state, a terminal bottom layer module (modem) initiates an RRC connection establishment (RRC connection establishment) process at an EUTRAN level, so that the terminal enters an RRC connected state.
The MCPTT server and the MCPTT client both belong to an application layer and do not sense the RRC state of the UE. The EUTRAN level (including the UE modem and eNodeB) knows the RRC state of the UE. The Application paging message contains the paged Application layer group ID (aiming at MCPTT group calling service) or Application layer user ID (aiming at MCPTT single calling service), and the MCPTT client can judge whether the terminal is a paging object according to the Application layer group ID or the user ID.
The specific processing flow of the application layer paging message of the existing protocol comprises the following steps:
1. the MCPTT Server decides to initiate a new call on the unicast channel or to switch an ongoing call to unicast.
2. The MCPTT sends an Application layer Paging (Application Paging) message on an MBMS multicast channel to inform the MCPTTClient to carry out call service data transmission on a unicast channel.
3. The MCPTT client triggers the UE to enter an RRC connection state, namely, the modem is informed to initiate an RRC connection establishment process.
4. The MCPTT server stops sending if the call service data has already been sent on the MBMS multicast channel.
5. The MCPTT server sends call service data to the MCPTT client on a unicast channel.
The relation between the MBMS architecture and the MC service client and MC service server is defined in 3GPP specification 23.280. The MBMS multicast channel may be used to transmit downlink signaling and service data from the MC service server to the MC service client. The MBMS multicast channel message is transmitted to the terminal over the Uu interface and received by the base layer module (modem).
For MCPTT, an MC service client in the framework is equal to the MCPTT client, and an MC service server is equal to the MCPTT server.
The inventor discovers that in the process of implementing the invention: the processing scheme of the application layer paging message has the problem that the power consumption of the terminal is large and the processing time is prolonged. The specific reason is analyzed as follows:
in the above processing scheme of the Application layer Paging message, when receiving an Application Paging message sent by an MBMS bearer, the UE defaults to an MCPTT client to analyze and process the message, and the MCPTT client triggers a UE bottom module (modem) to initiate an RRC connection establishment (RRC connection establishment) process. This then results in:
and 1, the UE upper layer application is frequently awakened, and the power consumption is large.
The ue modem is responsible for receiving data on the MBMS multicast channel and has the capability to parse MBMS messages itself. According to the existing scheme, when the modem receives the Application Paging message, the message needs to be transmitted to the MCPTTclient for processing, then the MCPTTclient triggers the UE modem to initiate an RRC connection process, and the processing time delay is long.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The main design concept of the invention is as follows: when receiving an application layer paging message sent by an MCPTT server on an MBMS multicast channel, the Modem needs to filter the application layer paging message, and when needing to initiate an RRC connection process, the Modem directly sends the message to enter an RRC connection state so as to avoid power consumption and time delay generated by processing the application layer paging message by the MCPTTClient, thereby effectively reducing the power consumption of the terminal for processing the application layer paging message and reducing the processing time delay.
Fig. 2 is a schematic flowchart of a method according to an embodiment of the present invention, and as shown in fig. 2, the method for processing an application layer paging message implemented according to the embodiment mainly includes:
In this step, when the UE arrives at the application layer paging message from the MCPTT server, the Modem in the UE needs to filter the message, that is, the application layer paging message is analyzed first, and it is determined whether the application layer paging message needs to be processed according to the analysis result, instead of being sent to the mcptttool in the UE for processing, so that when it is determined that the application layer of the UE needs to process, the Modem can directly initiate an RRC connection process when the UE is in an idle state, thereby reducing the power consumption of the UE and reducing the processing delay.
Preferably, the following method for determining whether the application layer paging message needs to be processed includes:
if the application layer paging message contains an MCPTT group identifier (MCPTT group ID), the modem judges whether the MCPTT group identifier exists in an interested group identifier list stored locally, if so, the processing is needed;
if the application layer paging message contains MCPTT user identification (MCPTTID), the modem judges whether the MCPTT user identification is the same as the locally stored user identification, if yes, the processing is judged to be needed.
and when the Modem judges that the processing is not needed, the Modem discards the application layer paging message.
Specifically, if the UE is in the CONNECTED state (RRC _ CONNECTED state), the modem does not initiate the RRC establishment procedure.
In step 202, the Modem directly processes the application layer paging message according to the determination result in step 201, so as to avoid large power consumption caused by frequent wakeup of the upper layer application of the UE, and as described above, the Modem directly initiates the RRC connection process without being triggered by the upper layer application, so as to effectively reduce the processing delay.
Further, in order to enable the MCPTT client to receive the application layer paging message for subsequent processing, when it is determined that the processing is required, the Modem may further send the application layer paging message to the MCPTT client of the UE, where the operation is not sequential to the initiation of the RRC connection process.
Corresponding to the foregoing method embodiment, an embodiment of the present invention further provides a device for processing an application layer paging message, where the device is disposed in a UE, and as shown in fig. 3, the device includes a Modem module and a mission critical push-to-talk client mcptttent.
The Modem is used for judging whether the application layer paging message needs to be processed or not according to the analysis result of the application layer paging message when receiving the application layer paging message sent by the key task push-to-talk server MCPTT server on the MBMS multicast channel; when the processing is determined to be needed, if the UE is in an RRC idle state, initiating an RRC connection process; when it is determined that the processing is not required, discarding the application layer paging message.
Preferably, the Modem is configured to, if the application layer paging message includes an MCPTT group identifier, the Modem determines whether the MCPTT group identifier exists in a locally stored interested group identifier list, and if so, determines that the processing is required; if the paging message of the application layer contains the MCPTT user identification, the modem judges whether the MCPTT user identification is the same as the user identification stored locally, if so, the processing is needed.
Preferably, the Modem is further configured to send the application layer paging message to the MCPTT client of the UE when it is determined that processing is required.
An embodiment of the present invention further provides a non-transitory computer-readable storage medium, which stores instructions, where the instructions, when executed by a processor, cause the processor to perform the steps of the embodiment of the method for processing an application layer paging message as described above.
Embodiments of the present invention also provide a computer system including the non-volatile computer-readable storage medium as described above and the processor having access to the non-volatile computer-readable storage medium.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
