Description

Method and system for establishing special load bearing of cluster audio and video service
Technical Field
The invention relates to the technical field of communication, in particular to a method and a system for establishing a special bearer for a cluster audio/video service.
Background
In the current B-TrunC standard, the dedicated bearer establishment for trunking voice and video in the roaming scenario across the core network is triggered by the procedure of visited-mobile management entity (V-MME) -visited-serving gateway (V-SGW) -home-packet data network gateway (H-PGW).
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a dedicated bearer establishment flow for a single-call audio/video service in a mid-span core network scenario in the prior art. In fig. 1, when receiving a Session Progress (183Session Progress) message sent by a home-trunking control function (H-TCF) device, a V-MME sends a Bearer Resource allocation (Bearer Resource Command) message to a V-SGW to trigger establishment of a voice/video Bearer.
In the specific implementation process, the V-MME processes the signaling, a Bearer Resource Command message needs to be sent to the H-PGW, and then the H-PGW sends a Bearer establishment Request (Create Bearer Request) message to establish the Bearer, which may result in a long time delay for Bearer establishment, a large amount of signaling, and more complex exception handling.
Because one message of the Bearer Resource Command can only carry one Bearer, when the trunking service is a video call, two Bearer Resource Command processes need to be initiated, and the V-MME needs to combine two messages in the NAS message, which further increases the time delay of Bearer establishment, increases the interactive signaling, and reduces the system performance.
Disclosure of Invention
In view of this, the present application provides a method and a system for establishing a dedicated bearer for a cluster audio/video service, which can reduce a time delay, save signaling overhead, and improve system performance.
In order to solve the technical problem, the technical scheme of the application is realized as follows:
a special bearing establishment method for a cluster audio/video service is applied to a cross-core network scene, and comprises the following steps:
when the H-TCF equipment sends a session progress message to a pipeline side, the H-PGW is informed through an internal interface to establish a special service bearer; the special service bearer is an audio bearer or an audio and video bearer;
when the H-PGW receives a notice of establishing a special service bearer sent by the H-TCF equipment, sending a bearer establishment request to establish a corresponding service bearer;
and when the H-PGW receives a bearer establishment response message sent by the V-MME, the H-PGW informs the H-TCF equipment of a bearer establishment result through an internal interface.
A special bearing establishing system for cluster audio/video service is applied to a cross-core network scene, and comprises the following components: H-TCF equipment and H-PGW;
the H-TCF equipment is used for informing the H-PGW to establish a special service bearer through an internal interface when the session progress message is sent to the pipeline side; wherein, the special service bearing is audio bearing or audio and video bearing;
the H-PGW is configured to send a bearer establishment request to establish a corresponding service bearer when receiving a notification of establishing a dedicated service bearer sent by the H-TCF device; and when receiving a bearer establishment response message sent by the V-MME, informing the H-TCF equipment of a bearer establishment result through an internal interface.
According to the technical scheme, when the H-TCF equipment sends the 183Session Progress message to the pipeline side, the H-PGW is triggered to initiate the establishment of the audio and video dedicated Bearer through the internal interface, and because the H-PGW can establish a plurality of dedicated bearers at one time when carrying out the Bearer establishment through the Create Bearer Request message and does not need to wait for the reestablishment of the Bearer Resource Command message sent by the V-MME, the scheme for establishing the cluster audio and video dedicated Bearer can reduce time delay, save signaling overhead and improve system performance.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings and examples.
The embodiment of the application provides a method for establishing a special bearer for a cluster audio/video service, which is applied to a cross-core network scene. When the H-TCF equipment sends a 183Session Progress message to the pipeline side, the H-PGW is triggered to initiate audio and video special Bearer establishment through an internal interface, and as the H-PGW establishes bearers through a Create Bearer Request message, multiple special bearers can be established at one time without waiting for the reestablishment of a Bearer Resource Command message sent by a V-MME, the scheme for establishing the cluster audio and video service special Bearer can reduce time delay, save signaling overhead and improve system performance.
The following describes in detail a dedicated bearer establishment procedure for a clustered audio/video service in an embodiment of the present application with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic diagram of a dedicated bearer establishment process for a clustered audio/video service in this embodiment. The method comprises the following specific steps:
step 201, when the H-TCF device sends a session progress message to the pipe side, it notifies the H-PGW to establish a dedicated service bearer through the internal interface.
The dedicated service bearer includes an audio bearer and an audio/video bearer.
Step 202, when the H-PGW receives the notification for establishing the dedicated service bearer sent by the H-TCF device, the H-PGW sends a bearer establishment request to establish the corresponding service bearer.
When the dedicated service bearer is an audio/video bearer, the dedicated service bearer to be established includes an audio bearer and a video bearer.
When the H-PGW sends a bearer establishment request, it may carry two bearers, an audio bearer and a video bearer, in one request.
In the prior art, as shown in fig. 1, when receiving a 183Session Progress message sent by an H-TCF device, a V-MEE sends a Bearer Resource Command message to an H-PGW to trigger establishment of a Bearer; in the specific implementation of the application, when the V-MEE receives a 183Session Progress message sent by the H-TCF device, the V-MME no longer sends a resource bearer allocation message to the V-SGW.
And because the V-MME simulates UE to send messages, only one Bearer can be carried in one Bearer Resource Command message, the implementation scheme of the application uses less interactive signaling and has less interaction among devices compared with the implementation scheme in a standard protocol, and the performance of the system can be improved better.
And 203, when the H-PGW receives the bearer establishment response message sent by the V-MME, notifying the H-TCF device of the bearer establishment result through the internal interface.
And when the H-TCF equipment receives the bearer establishment result notified by the H-PGW through the internal interface, determining whether the establishment of the special service bearer is successful or not according to the result, and whether the establishment of the special service bearer is triggered again or not.
In the embodiment of the present application, after the H-PGW sends the Create Bearer Request, Bearer establishment of a dedicated service is completed after receiving the Create Bearer Response, that is, Bearer establishment is performed through a process of the V-MME-V-SGW-H-PGW and is the same as a standard protocol, but in the specific implementation of the present application, if a plurality of bearers need to be established, the plurality of bearers may be carried in one Request.
During specific implementation, the H-TCF equipment and the H-PGW are added to simplify the flow of special service bearing through interaction of internal interfaces. The communication of the internal interface can be determined according to the deployment in the actual application, and does not limit which proprietary protocol is used to realize the sending of the dedicated service bearer notification.
Referring to fig. 3, fig. 3 is a schematic diagram of a bearer establishment process dedicated to a single call trunking audio/video service in this embodiment.
In fig. 3, the UE1 is taken as an example of a point-to-point single call flow initiated by a caller, and in an actual application, in a calling scenario and a single call scenario, a dedicated service bearer establishment flow of the caller and a dedicated service bearer establishment flow of a called are consistent in a dedicated bearer establishment flow of a pipeline side, which is not illustrated here.
In fig. 3, the implementation of steps 1 to 11 is the same as the prior implementation, and in the present application, step 8c is performed while step 9 is performed by the H-TCF device; and step 12a and step 12b in fig. 1 are not performed again when the V-MME performs step 11.
After the bearer establishment is completed, i.e. after step 13c, steps 14 to 22 are performed, as in steps 18 to 26 in fig. 1.
In the existing implementation, there is still a problem in that the Bearer establishment is triggered by sending a Bearer Resource Command message through a V-MME, because the Bearer Resource Command message only can transmit QCI, and cannot transmit the call priority of a cluster to an H-PGW, and the call priority and the pipe layer ARP priority mapping cannot be implemented for the H-PGW of a cluster user according to a 3GPP EPC architecture, Resource priority and preemption cannot be guaranteed from a pipe layer dedicated Bearer for a high call priority user of the cluster, and when radio resources are in shortage, the advantage of the high call priority user cannot be reflected.
For example, if the priority of user 1 is 5 and the priority of user 2 is 10, if a point-to-point call is made between users 1 and 2, the priority of the call may be the highest priority of the caller or both of them to participate in the calculation of the ARP priority, thereby affecting the Bearer establishment priority of the call, but the Bearer Resource Command message cannot transmit the call priority parameter, so the priority of the call cannot be adjusted accordingly.
The present application also provides the following solutions to the above problems:
the H-TCF device informs the H-PGW through the internal interface to establish a special service bearer, and further carries the call priority allocated to the call;
when the H-PGW receives the notice of establishing the special service bearer sent by the H-TCF equipment, the H-PGW further obtains the call priority in the notice, maps the call priority and the pipeline layer ARP priority, and prioritizes and seizes resources on the special bearer of the pipeline layer according to the priority level.
Based on the same inventive concept, the embodiment of the application also provides a dedicated bearer establishment system for the cluster audio/video service, which is applied to a cross-core network scene. Referring to fig. 4, fig. 4 is a schematic diagram of a system applied to the above technology in the embodiment of the present application. The system comprises: H-TCF equipment and H-PGW;
the H-TCF equipment is used for informing the H-PGW to establish a special service bearer through an internal interface when the session progress message is sent to the pipeline side; the special service bearer is an audio bearer or an audio and video bearer;
the H-PGW is used for sending a bearer establishment request to establish a corresponding service bearer when receiving a notification of establishing a special service bearer sent by the H-TCF equipment; and when receiving a bearer establishment response message sent by the V-MME, informing the H-TCF equipment of a bearer establishment result through an internal interface.
Preferably, the first and second liquid crystal films are made of a polymer,
and the H-TCF equipment is further used for enabling the V-MME not to send the resource bearing allocation message to the V-SGW when the session progress message is sent to the pipeline side.
Preferably, the first and second liquid crystal films are made of a polymer,
the H-PGW is further used for carrying an audio bearer and a video bearer in the bearer establishment request when the bearer establishment request is sent; when the dedicated service bearer is an audio/video bearer, the dedicated service bearer to be established includes an audio bearer and a video bearer.
Preferably, the first and second liquid crystal films are made of a polymer,
the H-TCF device is further configured to notify the H-PGW through the internal interface that a dedicated service bearer is established, where the notification carries a call priority assigned to the call;
the H-PGW is further configured to, when receiving a notification for establishing a dedicated service bearer sent by the H-TCF device, obtain a call priority in the notification, perform mapping between the call priority and a pipeline layer ARP priority, and perform resource prioritization and preemption on the pipeline layer dedicated bearer according to the priority level.
To sum up, when the 183Session Progress message is sent to the pipeline side through the H-TCF device, the H-PGW is triggered to initiate the establishment of the dedicated Bearer for audio and video through the internal interface, and since the H-PGW can establish multiple dedicated bearers at a time when carrying out Bearer establishment through the Create Bearer Request message, and does not need to wait for the reestablishment of the Bearer Resource Command message sent by the V-MME, the dedicated Bearer establishment scheme for the cluster audio and video service provided by the present application can reduce the time delay, save the signaling overhead, and improve the system performance.
In the existing standard implementation, the V-MME triggers Bearer establishment after receiving step 10, because one message of Bearer Resource Command can only carry one Bearer, when a service is a video call, two Bearer Resource Command processes need to be initiated, and two messages need to be merged in an NAS message, while in the scheme provided by the present application, Bearer establishment is directly triggered by an H-PGW, and a Create Bearer Request message can carry multiple bearers, so that implementation of message number, network element processing complexity, and exception handling standard is more complicated than optimization implementation;
in the technical scheme provided by the application, the H-TCF equipment establishes the bearer after receiving the step 8, and the H-PGW starts to establish the bearer only after receiving the 13a and the 13b in the standard implementation, and the time delay of the implementation scheme is saved by at least 20ms compared with that of the standard implementation scheme;
the technical scheme provided by the application can map the H-TCF equipment to the ARP priority of the bearer aiming at the service priority decided by the calling party and the calling party, thereby realizing the end-to-end QoS guarantee. The Bearer Resource Command message in the existing standard implementation cannot carry the priority to the H-PGW.
The technical scheme provided by the application conforms to the 3GPP standard, the standard H-PGW initiated special bearer establishment process is adopted, the butt joint of the S5/8 interface is simpler, and the modification of the S5/8 interface is not involved;
according to the technical scheme, the H-TCF equipment and the H-PGW are locally deployed, an interface between the H-TCF equipment and the H-PGW does not relate to the open problem, the interface can achieve QoS strategy decision through a standard protocol interface and an internal interface, and expandability is high.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
