The embodiment of the invention can't realize the problem of preferred MRFP at prior art, and the allocation rule of many kinds of MRFP of MRFC is provided, and makes MRFC according to the further preferred MRFP of described allocation rule, is used for providing the multimedia resource service to the user.
For simplifying subsequent descriptions, the MRFC that at first introducing the embodiment of the invention provides further distributes the allocation rule of MRFP as follows:
First allocation rule (selecting): set in advance the assignable MRFP of different AS according to application server AS, MRFC obtains the identification information of the AS of request resource from the resource request message that receives, mate first allocation rule according to this AS identification information and select MRFP; The principle of different MRFP of distributing the different AS that the embodiment of the invention provides can adopt different AS coupling different business abilities, the MRFP of capacity, for example the AS1 of service provider A can mate the strong MRFP1 of professional ability, and the AS2 of service provider B can mate the strong MRFP2 of professional ability;
Second allocation rule (according to user's input field Information Selection): apart from the nearest MRFP of user,, improve transmission quality according to user's input field information distribution, reduce the wasting of resources to reduce the transmission range of medium; MRFC can obtain user's input field information from the resource request message that receives, select MRFP according to described user's input field information matches second allocation rule;
The 3rd allocation rule (selecting): if there are a plurality of MRFP that meet the demands simultaneously according to the MRFP load, then MRFC selects the wherein the lightest MRFP of load according to the resource ratio of each MRFP that meets the demands, and load herein is meant that MRFP goes up certain class resource ratio of quantity allotted and total quantity;
The 4th allocation rule (user independently selects): MRFC is notified to the user with alternative MRFP, receive the selection that the user returns after, select MRFP according to the user; In the embodiment of the invention, MRFC prepares resource on each MRFP that has selected, carrying the resource information of each MRFP that has selected by Session Description Protocol in the resource request message notifies the user to continue to select MRFP in the MRFP that has selected, the result who selects MRFP also will select by user's automatic or manual returns to MRFC, and MRFC selects MRFP according to the selection result that the user returns.
Above-mentioned allocation rule can be by operator according to service needed configuration decision, those skilled in the art can also expand other allocation rule according to above-mentioned allocation rule, present specification does not repeat them here, for above-mentioned allocation rule, can also be its configuration preference level rank, for example stipulate first allocation rule＞second allocation rule＞the 3rd allocation rule＞the 4th allocation rule.
Be elaborated below in conjunction with the embodiment of accompanying drawing to the embodiment of the invention.
As shown in Figure 2, MRFC selects the detailed process of MRFP as follows:
Selection course in this step is same as the prior art, repeats no more.
If step 204 step 203 is selected at least two MRFP, carry out step 205; Otherwise selection course finishes.
The information that step 205, MRFC are carried according to INVITE with and MRFP self loading condition of same home domain, the priority-level of the allocation rule that is provided with according to operator is mated allocation rule one by one and continues selection MRFP from the selection result of step 203.
In this step, suppose that the allocation rule priority-level that operator is provided with is first allocation rule＞second allocation rule＞the 3rd allocation rule＞the 4th allocation rule, then MRFC at first selects MRFP according to first allocation rule according to the AS identification information, if select at least two MRFP, then MRFC again according to second allocation rule according to user's access domain selection MRFP, the rest may be inferred; If MRFC selects a MRFP according to certain allocation rule, then needn't select according to the subsequent allocations rule again.
Illustrate the specific implementation of such scheme below.
Fig. 3, does not therefore mark because S-CSCF is a transparent transmission SIP signaling between AS and MRFC for MRFC selects MRFP for the SIP signaling process figure that the user provides the playback service.
Step R1, AS send INVITE, the capable user's IP address 10.11.0.1 that carried of the c of the SDP in the INVITE body, and the From header field has carried AS identification information AS3.MRFC receives the INVITE that AS sends.
MRFC selects MRFP according to resource capability and the coding/decoding capability of each MRFP.
Suppose that the MRFP that MRFC selects according to resource capability and coding/decoding capability has M1, M2, M3, M4, M5.
