Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.
Fig. 1 is a flowchart of a method for negotiating video resolution provided by embodiment of the present invention, where this embodiment describes the method from the perspective of a core network device, and the core network device may be a core network device of a broadband trunking communication network, as shown in fig. 1, the method of this embodiment includes the following steps:
step S101, a core network device receives resolution information supported by the current service, which is sent by a calling UE, wherein the resolution information comprises resolution priority information.
The resolution supported by the calling UE in the current service is subsets of the resolution supported by the calling UE, when the calling UE initiates the service, the resolution supported by the current service is determined from the resolution supported by the calling UE, and information of the resolution supported by the calling UE in the current service is sent to the core network device, wherein the resolution supported by the calling UE comprises resolutions corresponding to various video services.
The information of the resolution supported by the calling UE for the current service includes, in addition to the priority information of the resolution, an index of a resolution format or a resolution format, and the core network device may determine the resolution format according to the resolution format index. Optionally, the information of the resolution supported by the current service of the calling UE may be carried in the service request message, or may be carried in other messages, which is not limited in this embodiment.

Figure BDA0001734905450000071
The service in this embodiment may be a video service, and the resolution supported by the calling UE in this service may be or more.
Step S102, the core network equipment determines the resolution used by the current service according to the acquired priority information of the resolution supported by the called UE and the priority information of the resolution supported by the current service of the calling UE.
The applicable scenario of this embodiment is that the core network device obtains priority information of resolution supported by the called UE in advance, and the called UE may report information of resolution supported by itself to the core network device when registering in the network, where the information of resolution supported by the called UE includes the priority information of resolution, and the resolution supported by the called UE includes resolutions corresponding to various video services. In a similar way, each UE in the network may report the priority information of the resolution supported by the UE to the core network device during registration, and subsequently, the core network device may determine the resolution used by the current service according to the priority information of the resolution supported by each UE. The core network device may also request the called UE for the information of the resolution supported by the called UE after receiving the information of the resolution supported by the service sent by the calling UE, and the called UE sends the information of the format and the priority of the resolution supported by the called UE to the core network device according to the request of the core network device.
For example, the resolution priority information is carried by a Session Initiation Protocol (SIP) message, an S1 message, or a Radio Resource Control (RRC) message, the S1 message is a message sent through an S1 interface, and the S1 interface is a communication interface between an Evolved node b (eNB) of a Long Term Evolution (LTE) network and an Evolved Packet Core (EPC).
If the resolution supported by the calling UE in the service is , the core network equipment judges whether the called equipment also supports the resolution, if the called UE also supports the resolution, the resolution is determined to be the resolution used by the service, and if the called UE does not support the resolution, the core network equipment returns negotiation failure to the calling UE.
When the resolution supported by the calling UE and the resolution supported by the called UE are multiple, the core network equipment determines the intersection of the resolution supported by the calling UE and the resolution supported by the called UE, and selects the resolution with the highest priority from the intersection as the resolution used by the service, so that the video quality can be ensured. And if the resolution supported by the current service of the calling UE and the resolution supported by the called UE do not have an intersection, the core network equipment returns negotiation failure to the calling UE.
Step S103, the core network equipment sends the resolution information used by the service to the calling UE and the called UE.
After determining the resolution used by the service, the core network respectively notifies the calling UE and the called UE, and the calling UE and the called UE subsequently use the resolution determined by the core network equipment to perform video display.
In this embodiment, the core network device receives information of resolution supported by the current service, which is sent by the calling UE, where the information of resolution includes priority information of resolution, and determines the resolution used by the current service according to the priority information of resolution supported by the called UE, which is obtained in advance, and the priority information of resolution supported by the current service of the calling UE, and sends the information of resolution used by the current service to the calling UE and the called UE. By defining the priority for the resolution, the core network device determines the resolution used by the service according to the priority information of the resolution, so that the optimal resolution can be selected, and the video effect is improved.

The resolution supported by the calling UE comprises resolutions corresponding to various video services.
Step S202, the called UE sends a registration message to the core network equipment, wherein the registration message comprises the format of the resolution supported by the called UE and the priority information of the resolution.
The resolutions supported by the called UE include resolutions corresponding to various video services, and step S201 and step S202 are not in sequence during execution, and may also be executed simultaneously.
Step S203, the calling UE sends a service request to the core network device, where the service request includes a format of resolution supported by the calling UE in this service and priority information of the resolution.
When the service is initiated, the calling UE carries the format of the resolution and the priority information of the resolution supported by the current service of the calling UE in the service request and sends the service request to the core network device, where the resolution supported by the calling UE may be or more.
Step S204, the core network equipment determines the resolution used by the current service according to the priority information of the resolution supported by the current service of the calling UE and the priority information of the resolution supported by the called UE.
The core network equipment firstly determines the intersection of the resolution supported by the calling UE and the resolution supported by the called UE, and then selects the resolution with the highest priority from the intersection as the resolution used by the service. And if the intersection is an empty set, the core network equipment returns negotiation failure to the calling UE.
Step S205, the core network device sends the information of the resolution used by the service to the calling UE.
Step S206, the core network equipment sends the resolution information used by the service to the called UE.
Steps S205 and S206 are executed without any sequence.
In this embodiment, the calling UE and the other UE report the format and priority information of the resolution supported by the calling UE and the other UE during registration, and subsequently, in a service initiation phase, the core network device determines the resolution used by the current service according to the priority information of the resolution supported by the current service of the calling UE and the information of the resolution supported by the called UE, so that an optimal resolution can be selected and a video effect is improved.
It should be noted that, in other embodiments of the present application, if even though the calling UE and the called UE send the format of the resolution and the priority information of the resolution supported by themselves to the core network device in the registration process, the called UE may subsequently determine the resolution used by the current service, that is, after the core network device receives the format of the resolution and the priority information of the resolution supported by the current service sent by the calling UE, the core network device sends the format of the resolution and the priority information of the resolution supported by the current service of the calling UE to the called UE, and the called UE determines the resolution used by the current service according to the priority information of the resolution supported by the current service of the calling UE and the priority information of the resolution supported by the called UE.

Step S302, the called UE determines the resolution used by the current service according to the priority information of the resolution supported by the called UE and the priority information of the resolution supported by the current service of the calling UE.
The called UE firstly determines the intersection of the resolution supported by the current service of the calling UE and the resolution supported by the called UE, and then selects the resolution with the highest priority from the intersection as the resolution used by the current service. If the intersection is the empty set, the called UE returns negotiation failure to the calling UE.
Step S303, the called UE sends the resolution information used by the service to the calling UE.
The called UE firstly sends the information of the resolution used by the service to the core network equipment, and the core network equipment sends the information of the resolution used by the service to the calling UE.
In this embodiment, the called UE receives information of resolution supported by the current service of the calling UE, which is sent by the core network device, where the information of resolution includes priority information of resolution, and determines the resolution used by the current service according to the priority information of resolution supported by the called UE and the priority information of resolution supported by the current service of the calling UE, and the called UE sends the information of resolution used by the current service to the calling UE. By defining the priority for the resolution, the called UE determines the resolution used by the service according to the priority information of the resolution, so that the optimal resolution can be selected, and the video effect is improved.

step S401, the calling UE sends a service request to the core network equipment, wherein the service request comprises the format of the resolution ratio supported by the current service of the calling UE and the priority information of the resolution ratio.
When the service is initiated, the calling UE carries the format of the resolution and the priority information of the resolution supported by the current service of the calling UE in the service request and sends the service request to the core network device, where the resolution supported by the calling UE may be or more.
Step S402, the core network equipment sends the format of the resolution ratio supported by the current service of the calling UE and the priority information of the resolution ratio to the called UE.
In this embodiment, the calling UE and the called UE do not report the format of the resolution supported by themselves and the priority information of the resolution to the core network device, and the core network cannot acquire the priority information of the resolution supported by the calling UE and the called UE, so that the core network device cannot determine the resolution used by the current service, and the core network device needs to send the priority information of the format of the resolution and the resolution supported by the calling UE by the current service to the called UE, so that the called UE determines the resolution used by the current service.
Step S403, the called UE determines the resolution used by the current service according to the priority information of the resolution supported by the current service of the calling UE and the priority information of the resolution supported by the called UE.
The called UE firstly determines the intersection of the resolution supported by the current service of the calling UE and the resolution supported by the called UE, and then selects the resolution with the highest priority from the intersection as the resolution used by the current service. If the intersection is the empty set, the called UE returns negotiation failure to the calling UE.
Step S404, the called UE sends the information of the resolution used by the service to the core network equipment.
