Embodiment
For making the object, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the embodiment in the application and the feature in embodiment be combination in any mutually.
In the present embodiment, by NAS (Non-Access-Stratum, Non-Access Stratum) layer protocol, in operation flow between terminal and network, carry voice coding/decoding capability or the video resolution of cluster definition, to realize core-network side, for voice coding/decoding capability or the video resolution of calling and called side, hold consultation.
In this enforcement, a kind of method of carrying out capability negotiation in LTE cluster network, is applied to cluster core-network side, as shown in 1, comprising:
In call setup flow process, this that send according to the caller colony terminal receiving called out the audio frequency and video ability information of ask use, the audio frequency and video ability information of supporting in conjunction with the caller colony terminal of having known and called colony terminal, determines that this calls out the audio frequency and video ability information of using; Wherein, the audio frequency and video ability information that request is used refers to voice coding/decoding capability or the video resolution that request is used; The audio frequency and video ability information of supporting refers to voice coding/decoding capability and/or the video resolution of support.
Cluster core net is called out after the audio frequency and video ability information use determining this, can also participate in by call setup flow process notice caller colony terminal and the called colony terminal of this calling.The audio frequency and video ability information that caller colony terminal and called colony terminal are used cluster core net to determine, correspondingly carries out concentrated speech business or cluster video traffic.
In addition, the audio frequency and video ability information of self supporting that cluster core net can be sent by colony terminal in attachment flow, knows the audio frequency and video ability information that this colony terminal is supported.
In the specific implementation, cluster core net determines that this selection algorithm of calling out the audio frequency and video ability information use can simply also can be complicated, and can configure.No matter but algorithm how, need the principle guaranteeing to be: this of selection algorithm output called out the audio frequency and video ability information of using, be preferentially the audio frequency and video ability information that caller colony terminal and called colony terminal are all supported, preferentially choose in the common factor of the audio frequency and video ability information that audio frequency and video ability information that caller colony terminal supports and called colony terminal support.
Preferably, the selection algorithm that cluster core net is used also can be distinguished to some extent for the type of calling out, such as: the selection algorithm that the individual calling to unique user of initiating for caller colony terminal is called out, with for this caller colony terminal, initiate can not be identical to the selection algorithm of a plurality of users' group calling, need independent design, because calling out within the scope of the audio frequency and video ability information that can support calling and called both sides, individual calling carries out complete to greatest extent negotiation, and although group calling also can be done complete negotiation in theory, but obvious inefficiency, therefore, should consider to use the selection algorithm of simplifying.
By two application examples of the present invention, be further described below.
Application example one
Be directed to individual calling and call out, a kind of capability negotiation method based on LTE cluster network, comprising:
Step 1, as shown in Figure 2, colony terminal, in attachment flow, sends Attach Request message to cluster core net, wherein carries voice coding/decoding capability and video resolution ability that this terminal is supported; After cluster core net is received, be kept in the user's context of this colony terminal, and to this colony terminal, reply to adhere to and accept message;
Step 2, as shown in Figure 3, a colony terminal is initiated cluster individual calling while calling out as caller colony terminal, to cluster core net, sends call request message, wherein carries voice coding/decoding capability or video resolution that this calls out ask use;
Step 3, cluster core net are asked voice coding/decoding capability or the video resolution used according to caller colony terminal, and the information such as the voice coding/decoding capability supported of caller and called colony terminal or video resolution (preserving in step 1), through selection algorithm correspondingly decision-making go out this and call out voice coding/decoding capability or the video resolution of using; If select unsuccessfully through selection algorithm, discharge this calling;
Step 4, cluster core net send respectively activation bearing request message to calling and called colony terminal, wherein carry this and call out voice coding/decoding capability or the video resolution of using, and notice is to caller colony terminal and called colony terminal respectively.
Application example two
Be directed to group calling, a kind of capability negotiation method based on LTE cluster network, comprising:
Step 1, as shown in Figure 2, colony terminal, in attachment flow, sends Attach Request message to cluster core net, wherein carries voice coding/decoding capability and video resolution ability that this terminal is supported; After cluster core net is received, be kept in the UE context of this colony terminal, and to this colony terminal, reply to adhere to and accept message;
Step 2, as shown in Figure 4, a colony terminal is initiated cluster individual calling while calling out as caller colony terminal, to cluster core net, sends call request message, wherein carries voice coding/decoding capability or video resolution that this calls out ask use;
Step 3, cluster core net are asked the information such as the voice coding/decoding capability of use or the voice coding/decoding capability of video resolution and caller and each called colony terminal support or video resolution (preserving in step 1) according to caller colony terminal, through selection algorithm decision-making, this calls out voice coding/decoding capability or the video resolution of using.Selection algorithm can be diversified, and according to mentioned above principle, adoptable selection algorithm is described follow-up;
Step 4, cluster core net send to caller colony terminal and activate bearing request message, to each called colony terminal, send respectively group calling context sets up request message or cluster multi call configuration messages, wherein carry this and call out voice coding/decoding capability or the video resolution of using, notice is to caller colony terminal and each called colony terminal.
In the specific implementation, the execution flow process of selection algorithm, as shown in Figure 5, comprising:
The type of the calling that A, judgement caller colony terminal are initiated is individual calling or group calling; If individual calling performs step B; Otherwise, execution step D;
Whether B, judgement caller colony terminal are asked voice coding/decoding capability or the video resolution used, be the audio frequency and video ability information that called colony terminal is supported; If so, the caller colony terminal of usining is asked the voice coding/decoding capability that uses or video resolution as selection result, selects flow process to finish; Otherwise, execution step C;
C, according to caller colony terminal, ask the type of the audio frequency and video ability information used, further judge whether the audio frequency and video ability information of caller colony terminal and the type that called colony terminal is supported has common factor, if had, in common factor, select accordingly any one voice coding/decoding capability or video resolution as selection result, select flow process to finish; If no, select unsuccessfully, select flow process to finish.Wherein, the type of audio frequency and video ability information at least comprises: voice coding/decoding capability and video resolution;
D, preferentially use caller colony terminal to ask voice coding/decoding capability or the video resolution of using, as final selection result, select flow process to finish.
In above-mentioned two application examples, the enforcement of selection algorithm is to carry out inner negotiation between the audio frequency and video ability information supported at calling and called colony terminal and the caller colony terminal audio frequency and video ability information asking to use, and in the strategy of consulting, has preferentially selected caller colony terminal to ask the audio frequency and video ability information of use.The result of consulting need be exported the audio frequency and video ability information that a caller colony terminal and called colony terminal are all supported.
Although it is chosen successfully that this selection algorithm has guaranteed as much as possible, also exist and select failed possibility.In order to reduce, select failed probability, can selection algorithm be optimized and be supplemented, in B step such as the algorithm in application example one, when cluster core net is not occured simultaneously in the audio frequency and video ability information (at least comprising voice coding/decoding capability information or audition ability information) of judging the type that caller colony terminal and called colony terminal support, to self whether supporting the transcoding function of respective type to judge, if support the transcoding function of respective type, so caller colony terminal is asked the audio frequency and video ability information transcoding using to change into any one audio frequency and video ability information that called colony terminal is supported, algorithm output just has two results, be respectively used to caller colony terminal and called colony terminal.If cluster core net is not supported the transcoding function of respective type, be judged as and select unsuccessfully, flow process finishes.Add the optimization of this part and supplement, can improve probability chosen successfully.
