Description

Voice format notification method and device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for notifying in a voice format.
Background
Currently, in the B-TrunC technology and the LTE technology, the VOIP voice format is supported by default. In the total length of VOIP format, the IP header occupies 50% of the entire data length.
In order to save the wireless resources of the air interface, B-Trunc introduces a voice format of adaptive multi-rate coding (AMR Over PDCP) based on a packet data convergence protocol, and the payload of the adaptive multi-rate coding (AMR) is transmitted at the air interface, namely only three AMR sub-streams are transmitted at the air interface, so that compared with the data of a standard VOIP format, 42 bytes are reduced, and the utilization rate of the air interface resources can be improved by fifty percent.
The inventor discovers that in the process of implementing the invention: in the above system supporting AMR Over PDCP and VOIP two voice formats, what voice format is used is negotiated by the terminal and the server, and the base station does not participate in the negotiation process, so the base station cannot know the voice format used before service data transmission. When the service data is transmitted, in order to reduce the overhead of air interface resources, when the AMR Over PDCP voice format is adopted, the air interface only transmits the AMR payload, but does not transmit the AMR Over PDCP voice format indication information, so that the base station side cannot know the voice format type adopted by the currently received service data, and thus the normal transmission of the voice service data cannot be realized.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
The voice format notification method implemented by the embodiment of the invention mainly comprises the following steps:
before transmitting service data for a user, an enhanced mobile management entity (eMMC) notifies a service base station of the user of a voice format type corresponding to the user by using a preset event process.
In order to save air interface overhead (that is, an air interface only transmits payload) when adopting an AMR Over PDCP voice format, and simultaneously, enable a base station to correctly process received data when transmitting service data, in the method, before transmitting service data, when a preset event process is executed, an emmme notifies a service base station of a user of a voice format type corresponding to the user, so that the base station can perform corresponding processing based on the notified voice format type when transmitting service data, thereby satisfying the service data transmission needs of the user.
Specifically, in order to enable the user to perform normal service data transmission after accessing the system supporting multiple voice formats, the event process at least includes a user establishment process, a user bearer establishment process, and a user bearer modification process. Specific notification modes are given below for the different procedures:
1. voice format type notification in user setup:
fig. 1 is a schematic diagram illustrating notification of a voice format type when a user is established, as shown in fig. 1, in the establishment process of the user, an eMME sends a GROUP CALL CONTEXT SETUP REQUEST (GROUP CALL CONTEXT SETUP REQUEST) message to a serving base station of the user, and the GROUP CALL CONTEXT SETUP REQUEST message carries the voice format type.
Here, when a user needs to be established, the group call context establishment request in the process is utilized to realize the notification of the corresponding voice format type, so that the base station can acquire the corresponding voice format type before the user service data transmission, so that the resource configuration matched with the corresponding voice format type can be performed for the user, and then the service transmission of the user can be normally processed.
2. Voice format type notification in the user bearer establishment process:
fig. 2 is a schematic diagram illustrating notification of a voice format type when a user bearer is established, and as shown in fig. 2, in the process of establishing a bearer for the user, the eMME sends a GROUP TE-RAB SETUP REQUEST (GROUP TE-RAB SETUP REQUEST) message to a serving base station of the user, and the GROUP TE-RAB SETUP REQUEST message carries the voice format type.
Here, when a user bearer needs to be established, the notification of the corresponding voice format type is realized by using the group call context establishment request in the process, so that the base station can acquire the corresponding voice format type before the user service data is transmitted, and the base station can normally process the service transmission of the user later.
3. Voice format type notification in the user bearer modification process:
fig. 3 is a schematic diagram illustrating notification of a voice format type when a user modifies a bearer, and as shown in fig. 3, in the process of modifying a bearer for the user, the eMME sends a GROUP TE-RAB modification REQUEST message to a serving base station of the user, where the GROUP TE-RAB modification REQUEST message carries the voice format type.
Further, in order to ensure that the user can still perform normal transmission of voice service data after performing inter-station handover, the target base station may be notified of the voice format type through the eMME when performing inter-station handover, which is specifically as follows:
when the user is switched among stations, the eMMC transmits a switching request message to a corresponding target base station after receiving the switching request message sent by a source service base station of the user, wherein the switching request message carries the voice format type to indicate the voice format used by the current context.
The difference from the existing system is that when the inter-station handover is performed for the user, the switching request message received by the eGME carries the voice format type to indicate the voice format used by the current context, that is, the switching request message sent by the source service base station carries the voice format type, and then the eGME forwards the switching request message to the target base station, so that the target base station can establish a corresponding user plane for the user as soon as possible according to the voice format type indicated by the switching request message, and the base station to which the user is switched can be ensured to perform correct transmission processing on the user service data.
The embodiment of the present invention further provides a voice format notification apparatus corresponding to the foregoing method embodiment, where the apparatus is located in an enhanced mobile management entity eMME, and mainly includes:
and the notification unit is used for notifying the voice format type corresponding to the user to a service base station of the user by utilizing a preset event process before transmitting the service data to the user. The event process comprises a user establishing process, a user bearing establishing process and a user bearing modifying process.
Preferably, the notifying unit is configured to send a group call context setup request message to a serving base station of the user in a setup process of the user, where the group call context setup request message carries the voice format type.
Preferably, the notifying unit is configured to send a GROUP TE-RAB SETUP REQUEST message to the serving base station of the user during the process of establishing the bearer for the user, where the GROUP TE-RAB SETUP REQUEST message carries the voice format type.
Preferably, the notifying unit is configured to send a GROUP TE-RAB modification REQUEST message to the serving base station of the user during bearer modification for the user, where the GROUP TE-RAB modification REQUEST message carries the voice format type.
Preferably, the notifying unit is further configured to, when performing inter-station handover for the user, after receiving a handover request message sent by a source serving base station of the user, transparently transmit the handover request message to a corresponding target base station, where the handover request message carries the voice format type to indicate a voice format used by a current context.
Further, the present application provides a non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the steps of the voice format type notification method embodiment as previously described.
Further, the present application provides an electronic device comprising the non-volatile computer-readable storage medium as described above, and the processor having access to the non-volatile computer-readable storage medium as described above.
