Description

A kind of multimedia broadcast/multi broadcast service Iu signaling connects method for releasing
Technical field
The present invention relates to multimedia broadcast/multi broadcast service (MBMS) business in the Wideband Code Division Multiple Access (WCDMA), specifically relate to a kind of MBMS Iu signaling and connect method for releasing.
Background technology
Through insistent development of more than ten years, digital TV Broadcasting Techniques has been driven ripe and has been moved towards to use day.From cable digital TV technology (for example DVB-C), satellite digital TV technology (as DVB-S) arrives the terrestrial DTV technology (as DVB-T, the TDS-OFDM of China etc.), various digital TV broadcasting services all over the world mushroom development get up, brought remarkable economical and social benefit to society.
As next step developing direction and the mobile communication of digital television techniques combine digital television techniques---the mobile video broadcast technology has been walked out the backstage, floating upper table surface is subjected to various aspects and more and more payes attention to.Utilize the mobile communication terminal of existing mobile phone and so on to receive digitized video broadcasting business, can make full use of the high advantage of the broadcast technology availability of frequency spectrum and move the characteristics that receive, make the mobile subscriber can receive needed TV programme whenever and wherever possible.This application technology has significant market development prospect, might become the very important business of next generation mobile communication.
At the mobile video broadcast technology, each state has all begun to drop into the man power and material and has developed various solutions are provided, and develops the DVB-H standard and has carried out outfield experiments on existing terrestrial DTV standard DVB-T basis as Europe.
In order to tackle the challenge of mobile video broadcast technology, 3GPP organizes the MBMS business of also having released in the WCDMA system.The MBMS service is by utilizing the WCDMA wireless communication system to provide video and data broadcasting service to the user, can reduce the operator wireless communication system equipment investment, terminal also can utilize existing radio frequency and baseband processing chip to remove receiving broadcast signal, reduces the terminal cost.And utilize independent broadcast system such as DVB-H that respective service is provided, and must the sole investment networking, terminal also must have two cover radio frequency and band processing systems (as the reception process chip of WCDMA, the reception process chip of DVB-H).In sum, the WCDMA system provides broadcast service by the MBMS business to the user, has significant advantage for the DVB-H system, will inevitably be subjected to operator and user's welcome, becomes the main flow of mobile video broadcast technology.
The processing procedure of existing MBMS system comprises that mainly being used for UE adds MBMS Service Activation (the MBMS Service Activation) process that has the MBMS business now, the MBMS session that the MBMS session that is used to start a MBMS business begins (MBMS Session Start) process and is used to stop an existing MBMS business stops and end of service (MBMS Session Stop and ServiceTermination) process.
MBMS Session Start process by wherein can set up between the SGSN of CN and RNC that the Iu signaling connects and corresponding SCCP connects, and the RAB of this MBMS business of carrying.
For MBMS Session Stop and Service Termination process wherein, when a MBMS business stopped to serve, system was released in by this process and is the resource of this traffic assignments among RNC and the CN.Specifically, when system's decision stops a MBMS Session, SGSN among the CN can send RANAP MBMS Session Stop message to the RNC of its registration to all, notifies subordinate RNC to discharge relevant RAB resource and is connected with the Iu signaling of setting up for this business.RNC is after receiving this Stop message, and RNC starts the dispose procedure that RAB is connected with Iu, and returns RANAPMBMS Session Stop Response message.
This MBMS Session Stop and Service Termination process all has description at present in 3GPP 25.410 and 3GPP 25.413 these two agreements.But all have problems in these two agreements: after RNC sent MBSM SESSION STOP message, SGSN still may utilize original Iu signaling to connect and send other message to RNC at SGSN; After SGSN sent MBMS Session StopResponse message, RNC still may utilize original SCCP to connect and send other message to SGSN at RNC.Obviously these two problems can cause handling confusion, thus consume system resources.
Just begin to start the dispose procedure that this MBMS Iu signaling connects about being problematic in that after RNC receives RANAP MBMS SESSION STOP message of MBMS Session Stop existence among the 3GPP 25.413 at present.And RNC feeds back to the RANAP MBMS SESSION STOPRESPONSE message of SGSN also is connection-oriented message, when this message of RNC attempt transmission, the Iu signaling connects and corresponding SCCP connects and is in dispose procedure, and this message will be failed, and causes the whole process can not normal termination.
And about the regulation which end to be initiated the dispose procedure of SCCP connection by conflicting place is arranged in the description of these two agreements, this conflict can cause system normally to move, and corresponding SCCP connection then can't normally discharge.
Specifically, regulation among the agreement 3GPP 25.410, when MBMS Session stopped, the SCCP of this session correspondence connected and must initiate the dispose procedure that SCCP connects by the SCCP entity of the notice of the RANAP entity among SGSN SGSN.
And regulation among the agreement 3GPP 25.413, when MBMS Session stopped, the SCCP of this session correspondence connected and must initiate the dispose procedure that SCCP connects by the SCCP entity of the notice of the RANAP entity among RNC RNC.
Like this, if the RANAP entity among the RNC adopts the regulation of agreement 3GPP 25.413, and the SCCP entity adopts the regulation of agreement 3GPP 25.410, and then this RNC SCCP entity can refuse to discharge the SCCP connection.Similarly, if the RANAP entity among the SGSN adopts the regulation of 3GPP 25.410, and the SCCP entity adopts the regulation of 3GPP 25.413, and then this SGSN SCCP entity also can refuse to discharge the SCCP connection.
Figure 1 shows that the handling process that agreement 3GPP 25.413 provides, corresponding following steps:
Step 1, SGSN indicate according to the upper strata, and decision discharges the MBMS SESSION that is working.SGSN RANAP entity will be constructed corresponding RANAP MBMS SESSION STOP message, and it is carried out the ASN.1 coding;
RANAP MBMS SESSION STOP message after step 2, SGSN RANAP entity will be encoded is notified to SGSN SCCP entity by the N-DATA.REQ primitive of SCCP, comprises the RANAP MBMS SESSION STOP message behind the coding in the entrained parameter of this primitive;
Step 3, SGSN SCCP entity are transferred to this RANAP MBMS SESSION STOP message the RNC SCCP entity of equity according to the parameter of carrying among the SCCP primitive N-DATA.REQ by the protocol layers such as MTP3b, M3UA of SCCP message such as DT1/DT2 and bottom carrying;
Step 4, RNC SCCP entity utilize SCCP primitive N-DTAT.IND notice RNCRANAP entity again with the RANAPMBMS SESSION STOP message that is comprised in the SCCP message that receives;
Step 5, RNC RANAP entity begin to discharge relevant Radio Resource by after resolving acquisition RANAP MBMS SESSION STOP message;
Step 6, RNC RANAP entity begin to discharge the Iu signaling by SCCP primitive N-DISCONNECT.REQ notice RANAP SCCP entity and connect;
Step 7, RNC SCCP entity are initiated MBMS Iu signaling and are connected dispose procedure; Comprise that the RNCSCCP entity generates SCCP RELEASED message, and by SCCP message this RELEASE message is sent to SGSN SCCP entity, these two entities are realized the release that the Iu signaling connects by interacting message afterwards.
Step 8, RNC RANAP entity structure RANAP MBMS SESSION STOPRESPONSE message, and it is carried out ASN.1 encode;
RANAP MBMS SESSION STOPRESPONSE message after step 9, RNC RANAP entity will be encoded is notified to RNC SCCP entity by SCCP primitive N-DATA.REQ, comprises the ANAP MBMS SESSION STOP RESPONSE message behind the coding in the DATA parameter of this primitive;
Step 10, RNC SCCP entity are transferred to corresponding ANAP MBMS SESSION STOP RESPONSE message the SGSNSCCP entity of equity according to the parameter of carrying in the SCCP N-DATA.REQ primitive by the protocol layers such as MTP3b, M3UA of SCCP message such as DT1/DT2 and bottom carrying;
The RANAP MBMS SESSION STOP RESPONSE message that is comprised in the message that step 11, SGSN SCCP entity are sent RNC SCCP entity utilizes SCCP primitive N-DATA.IND to be notified to SGSN RANAP entity;
Step 12, SGSN RANAP entity to the RANAP MGMS SESSION STOP message that receives decode resolve after, stop MBMS SESSION STOP process, and SGSN RANAP entity discharges respective resources;
Step 13, this step are optional step, comprise RNC SCCP entity after receiving the SCCP N-DISCONNECT.REQ primitive that RNC RANAP entity sends, and will return a SCCPN-DISCONNECT.CNF primitive and give RNC RANAP;
Step 14～15, this step are optional step also, are included in the SCCP signaling and connect in the dispose procedure, and SGSN SCCP entity will be released with the corresponding SCCP connection of primitive SCCP N-DISCONNECT.IND notice SGSN RANAP entity; SGSN RANAP entity then will feed back to SGSN SCCP entity with primitive SCCPN-DISCONNECT.RES.
From above treatment step as can be seen, there are some defectives in this flow process.
First defective of agreement is aforementioned because of the incompatible problem that may bring of agreement.Specifically, from above-mentioned steps 6 as can be seen, RNC RANAP entity need notify RANAP SCCP entity to begin to discharge the SCCP connection.And if this RANAP SCCP entity adopts is the regulation of agreement, then can refuses this dispose procedure, thereby cause MBMS SCCP to connect release failure.
From above-mentioned flow process as can be seen, in above-mentioned steps 9, RNC RANAP entity is after being notified to RNC SCCP entity with RANAPMBMS SESSION STOP RESPONSE message by SCCP primitive N-DATA.REQ, in the step 10, RNC SCCP entity then needs to give SGSN SCCP entity with this message by the SCCP transmission of messages, and MBMS SCCP connected to have discharged probably and finished this moment, this just causes RNC SCCP entity this SCCP message can not be sent to RNC SCCP entity, thereby causes whole M BMS SESSION STOP procedure failure.
In sum, present SCCP connects release embodiments and has number of drawbacks, and these defectives can cause the failure of SCCP dispose procedure.
