Description
Technical field
The present invention relates to a kind of grouping accessing method, relate in particular to the processing method that a kind of packet-based CDMA2000 Access Network is realized bear format negotiation.
Background technology
Packet-based CDMA2000 Access Network can adopt the IP switching technology to be linked into the CDMA2000 core net that realizes traditional mobile terminal territory (LMSD).Moving switching subsystem (MSS) system with traditional circuit domain compares, the variation of CDMA2000 core net maximum is to call out separating of control and carrying, replace the Time Division Multiplexing technology with the Packet Based Network technology, traditional mobile switching centre (MSC) network element is evolved into the simulator (MSCe of mobile switching centre, the MSC simulator) and media gateway (MGW), MSCe provides and calls out control and mobile management function, MGW provides media control function, and transfer resource is provided, have the Media Stream operating function.
Media gateway MGW (Media Gateway) need connect according to selecting allocation units (SDU, Selection/Distribution Unit) to set up carrying in relevant information that obtains and the base station system under the control of MSCe.The bearer negotiation process has been introduced two notions: do not have sign indicating number line translation operation (TrFO, TranscoderFree Operation) and long-range code conversion operation (RTO, Remote Transcoder Operation), for these two functions, the 3GPP2 standard-required is as essential realization function.
TrFO transmits compressed voice by removing codec between the conventional mobile phone on the bearer path of Packet Based Network.Vocoder (Transcoder) both can with wireless access network (RAN, Radio Access Network) association, also can be related with MGW.By only transmitting compressed voice, TrFO has improved bandwidth availability ratio and has reduced the loop time-delay.TrFO also can improve speech quality, and TrFO is not used in the networking telephone (VoIP, Voice Over Internet Protocol), and TrFO is the ability of traditional mobile terminal territory (LMSD).TrFO has used the out-of-band signalling ability that comprises two end nodes negotiation code/decode types.If two end nodes can carry out same coding-decoding operation, so, just might use single preferred compressed voice to transmit on the net in whole group.TrFO a kind ofly exempts from yard mechanism of type transducer in core net a call arrangement, and the required Transcoder of this calling is arranged in portable terminal (MS).
RTO is a kind of mechanism of giving a call arrangement sign indicating number type transducer in core net.RTO does not also mean that cascade (Tandem) operation.For example, in order to support the calling of portable terminal-public fixed telephone network (MS-PSTN), need in MGW or base station controller (BSC), insert sign indicating number type transducer.For the calling of MS-MS, if the codec difference of two MS then needs a sign indicating number type transducer in the network.This is different from typical Tandem usage, and it is a kind of public rather than transmit by unique agreement to use 2 sign indicating number type transducers that the sign indicating number type of 2 end nodes is converted to.RTO is the special case of TrFO.No matter be TRO or TrFo, all need BS and MSCe to carry out the negotiation of bear format.The negotiation of bear format is undertaken by out-of-band signalling, realizes by BSAP (Base Station Application Part, base station application part) signaling on Alp (interface of carrier signaling between BS and the MSCe) interface between Access Network and the core net.The negotiation of BS and MSCe bear format comes down to the negotiation of MS and MSCe bear format.BS is as middle third party, and role is to coordinate MS and MSCe, finishes both bear format negotiation.Because TrFO calls out the participation do not need vocoder, so the MGW reverse frames that only needs transparent transmission SDU to send.Can alleviate the burden of MGW so greatly, and speech quality can be guaranteed also.So carry out bear format negotiation the time, a basic principle is to realize TrFo as far as possible.MSCe is in order to finish TrFO, can not use the base station to dispose the vocoder of oneself for its business option, but can carry another kind of bear format by bearer update request message (Bearer Update Request), use this bear format to come to carry out the negotiation of bear format with BS.Similarly, a kind of bear format can be carried by sending bearer update order (Bearer Update Required) to MSCe in the base station, uses this bear format and MSCe to carry out the negotiation of bear format.Receive the bearer update request message of MSCe in the base station after, professional change need be finished in the base station, carries out service negotiation with mobile phone.If the result of bear format negotiation can't realize TrFo, then need to carry out RTO.
Stipulated to carry out bear format negotiation in the related procedure of existing communication agreement (Interoperability Specification (IOS) for CDMA2000Access Network Interfaces-Part 3 Features (3G-IOS v5.0)), but do not proposed negotiation method.
Summary of the invention

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
If when generating the bear format tabulation that BSC supports, service negotiation is not also successfully carried out with mobile communication terminal in the base station, then in Fig. 6, do not have the SO_Nego correspondence bear format this.
The present invention is used to realize that the negotiation of BS and MSCe bear format is that BS generates the bear format tabulation that BS supports, it bear format tabulation fashion that comprises that two kinds of situation: 1.BS generation BS support is not known the bear format tabulation that MGW supports; 2.BS generate and known the bear format tabulation that MGW supports when the bear format of BS support is tabulated.No matter which kind of situation needs all to determine that in the calling procedure kind business option (SO) carries out service negotiation with portable terminal, referred to herein as BTS service option (BS_SO).Business option in portable terminal call message or the page-response message is called portable terminal call message business option (MS_SO); In call message or the page-response message with selectable business option be the optional affair option (ALT_SO) of choosing a job of portable terminal; The bear format tabulation that MGW supports is MGWFormatIDList.
As shown in Figure 1, in step S1, at first when BS generates the bear format tabulation that brings MSCe, judge whether the bear format tabulation that known road MGW supports; When if BS generates the bear format tabulation that brings MSCe, still do not know the bear format tabulation that MGW supports, then execution in step S3 generates the bear format tabulation that brings MSCe according to BTS service option BS_SO and the optional affair option ALT_SO (Alternative ServiceOption) that chooses a job of portable terminal; When if BS generates the bear format tabulation that brings MSCe, known the bear format tabulation that MGW supports, execution in step S2 then supports the bear format tabulation to generate the bear format tabulation that BS brings MSCe according to BTS service option BS_SO and ALT_SO and MGW.
In the prior art, when generating the bear format tabulation that brings MSCe, do not know that still the situation of the bear format tabulation that MGW supports has following several:
1, normal voice calls, the mobile phone caller, BS brings the bear format that MSCe BS supports in CM Service Request Message, and this moment, BS can't be known the bear format that MGW supports;
2, normal voice calls, the mobile phone caller, when sending CM Service Request Message to MSCe, BS can't have the bear format that BS supports in this message.According to the agreement regulation, MSCe can not have the bear format that MGW supports yet in Assignment Request message.BS will bring the bear format that MSCe BS supports in AssignmentComplete message.This moment, BS also can't be known the bear format that MGW supports;
3, normal voice calls, mobile phone called party, MSCe does not bring the bear format tabulation that BS MGW supports in Paging Request message, and BS BS in Paging Response message brings the bear format tabulation that MSCe BS supports;
4, the concurrent audio call of data, the mobile phone caller, BS brings the bear format tabulation that MSCe BS supports in Additional Service Request message;
5, the concurrent audio call of data, mobile phone called party, MSCe does not bring the bear format tabulation that BS MGW supports in Additional Service Notification message, and BS BS in Additional ServiceRequest message brings the bear format tabulation that MSCe MGW supports;
6, in the direct-cut operation, target side BS, MSCe do not comprise the bear format tabulation that MGW supports in Handoff Request message, and according to the agreement regulation, BS must bring the bear format tabulation that MSCe BS supports in Handoff Request Ack message.
In the prior art, when BS generates the bear format tabulation that brings MSCe BS support, known that the situation of the bear format tabulation that MGW supports has following several:
1, normal voice calls, mobile phone called party, MSCe comprises the bear format tabulation that MGW supports in Paging Request message, and BS comprises the bear format tabulation that BS supports in Paging Response message.
2, normal voice calls, mobile phone called party, MSCe comprises the bear format tabulation that MGW supports in Paging Request message, and BS can't be known the bear format tabulation that BS supports when sending Paging Response message to MSCe, then according to agreement, BS can comprise the bear format tabulation that BS supports in Assignment Complete message.In this case, BS has been known the bear format tabulation that MGW supports;
3, the concurrent audio call of data, mobile phone called party, MSCe comprises the bear format tabulation that MGW supports in Additional ServiceNotification message, and BS comprises the bear format tabulation that BS supports in Additional ServiceRequest message;
4, the concurrent audio call of data, mobile phone called party, MSCe comprises the bear format tabulation that MGW supports in Additional ServiceNotification message, BS can't comprise the bear format tabulation that BS supports in Additional ServiceRequest message, then BS will inevitably comprise the bear format tabulation that BS supports in AssignmentComplete message, at this moment, BS has been known the bear format tabulation that MGW supports;
5, in the switching, target side BS, MSCe comprises the bear format tabulation that MGW supports in Handoff Request message, and stipulate according to agreement, BS must bring the bear format tabulation that MSCeBS supports in Handoff Request Ack message, at this moment, BS has got access to the bear format tabulation that MGW supports.
When generating the bear format tabulation, BS whether known that in fact the bear format tabulation that MGW supports is embodied in the algorithm difference of determining BS_SO (service in base station option).Following elder generation is described definite algorithm of BS_SO.Also be divided into bear format parameter and the definite BS_SO fashion of having known the MGW support when determining BS_SO and do not know two kinds of situations of bear format parameter that MGW supports.
BS is not known under the situation of the bear format tabulation that MGW supports as yet when determining BS_SO, it determines BS_SO according to MS_SO (in portable terminal call message or the page-response message with business option) and ALT_SO (in call message or the page-response message with selectable business option), as shown in Figure 2, concrete steps are as follows: step S311, judge whether MS_SO is 8k; If not, then carry out step S312, with MS_SO as BS_SO (generally speaking all with MS_SO as BS_SO); If, execution in step S313 then, the BS_SO value is first value among the ALT_SO.This is because present 8k is off-gauge business option in the IOS agreement, does not also define the bear format of 8k correspondence.After determining BS_SO, execution in step S314.
Business option after this consultation business service option (SO_Nego) expression BS finishes with the portable terminal negotiation.Do not have the bear format of repetition in the bear format tabulation that generates, if after the bear format put into the bear format that tabulation has had repetition is arranged, then this bear format is not put into tabulation.
When the bear format tabulation fashion that BS generation BS supports was not known the bear format tabulation of MGW support, the RTP Payload Type value of FormatID correspondence was filled in according to correct span by BS is next, and can not repeat.As shown in Figure 3, the step that generates the bear format tabulation that BS supports is as follows: step S314 judges whether to have finished the negotiation with portable terminal; If finish, then execution in step S315 inserts the bear format of SO_Nego correspondence earlier in tabulation, and Tag Type is filled out is 2, represents that the SO of this bear format correspondence consults with portable terminal, continues step 316-319 then; If also do not finish negotiation with portable terminal, then directly arrive step S316, in tabulation, insert the bear format of BS_SO correspondence, and Tag Type is filled out is 3; Step S317 inserts the bear format of MS_SO correspondence in tabulation, and Tag Type is filled out is 3; Step S318 puts into bear format tabulation with the bear format of ALT_SO correspondence, and Tag Type is filled out is 3; Step S319 inserts the bear format of Dual Tone Multifrequency correspondence in bear format tabulation, and Tag Type is filled out is 1.Thereby when not knowing the bear format tabulation of MGW support as yet, generate the bear format tabulation that BS supports, as shown in Figure 6.In above-mentioned 5 steps (S315 to S319), the arrangement in the bear format tabulation of the bear format of generation and relevant parameters does not have priority orders.
BS has got access under the situation of the bear format tabulation that MGW supports when determining BS_SO, it determines BS_SO according to MGWFormatIDList, MS_SO and ALT_SO, as shown in Figure 4, concrete steps are as follows: step S211, search Tag Type among the MGWFormatIDList earlier and be 2 bear format, i.e. the bear format that consults with portable terminal; Execution in step S212 then judges that whether identical with MS_SO this bear format corresponding service option or this bear format corresponding service option whether in ALT_SO; If this bear format corresponding service option or this bear format corresponding service option identical with MS_SO be in ALT_SO, execution in step S213 then, with this bear format corresponding service option as BS_SO; If this bear format corresponding service option with MS_SO is inequality or this bear format corresponding service option not in ALT_SO, then can not determine BS_SO, execution in step S214 travels through MGWFormatIDList; Execution in step S215 judges whether the bear format of MS_SO correspondence appears at wherein then; If the bear format of MS_SO correspondence appears among the MGWFormatIDList, execution in step S216 then, with MS_SO as BS_SO; Otherwise execution in step S217, traversal ALT_SO and MGWFormatIDList; Execution in step S218 judges whether the bear format value of ALT_SO correspondence appears among the MGWFormatIDList then; If the bear format value of ALT_SO correspondence appears among the MGWFormatIDList, then execution in step S219 is decided to be BS_SO with this ALT_SO; If MGWFormatIDList and ALT_SO are identical without any value, execution in step S220 then, with MS_SO as BS_SO.After determining BS_SO, execution in step S221.
Wherein, the corresponding relation of FormatID and Service Option sees Table 1.In the table 1, ServiceOption represents business option; Description represents the description to business option; Bearer Format ID represents bear format; Encoding Name represents the bear format corresponding coding manner; RTP PayloadType Value represents the PT value of RTP bag, and it is corresponding one by one with bear format; Meaning represents the description to the code/decode format of bear format correspondence.Two values of front are tables in the agreement, and 4 values of back are tables in the agreement.In addition, can only comprise these two row of Service Option (business option), Bearer Format ID (bear format) in this form gets final product.
The corresponding relation of table 1:Format ID and Service Option.
