Description
Technical field
The present invention relates to 3-G (Generation Three mobile communication system), particularly a kind of method of attachment of removing a plurality of user equipment specific Iu signalings simultaneously.
Background technology
MBMS is formulating relevant criterion for it to carry out a standardized new business in the 3-G (Generation Three mobile communication system) partner program.The MBMS business is a kind of unidirectional point to the business of multipoint system (promptly broadcasting out multi-medium data from single data source is sent to a plurality of users through Network Transmission and receives).The maximum characteristics of this business are that it can effectively utilize Radio Resource and Internet resources.The MBMS business is mainly used in the wireless communication network system, as Wideband Code Division Multiple Access (WCDMA) communication system, and global system for mobile communications etc.The transmission of business datum will be passed through basically among the MBMS: transmission in data source transmission, go-between transmission, the purpose cell null, user receive such plurality of processes.Fig. 3 is a wireless communication system logical network equipment drawing that the MBMS business can be provided, and in fact MBMS has utilized general grouped wireless data service (hereinafter to be referred as GPRS) network as core transport network in the figure.As shown in Figure 3, broadcasting and multicast service center (hereinafter to be referred as BM-SC) are the data sources that sends the MBMS business datum; Gateway GPRS Support Node (hereinafter to be referred as GGSN) is used for being connected of GRPS network and external network (as the INTERNET network); Gateway GPRS Support Node connects BM-SC and the MBMS data is sent to specific Serving GPRS Support Node (hereinafter to be referred as SGSN) in the MBMS business; CBC is the data source of Cell Broadcast CB, by with CBC and BM-SC interconnection, makes CBC that MBMS can be provided professional declaration function in MBMS; SGSN is used for that UE is carried out access control and mobile management and simultaneously the MBMS data of coming from GGSN is sent to specific radio-cell controller (hereinafter to be referred as RNC); RNC is used for controlling one group of base station and multi-medium data is sent to specific base stations; Aerial physical channel is set up for the MBMS business of certain sub-district in the base station under the control of RNC; Subscriber terminal equipment (hereinafter to be referred as UE) is the terminal equipment that receives the MBMS data.
Provided the MBMS business among Fig. 4 and be established to all processes that end user is left from business declaration, user's adding, service announcements, radio bearer.
401 subscribe to the contact of setting up between user and the service provider, and authorized user can receive relevant MBMS service.
The MBMS business that 402 professional declarations notify the user to provide.For example, system in the afternoon 7:00 relay a football match in areas of Beijing.
403 add the expression users adds a group, promptly the user tell network he or she be ready to receive this multicast service.
404 MBMS sessions begin to represent that being established as the MBMS transfer of data sets up Internet resources.
405 MBMS notice is informed the MBMS transfer of data that the user will carry out at once.
406 data transfer representation MBMS business data transmission are to user's process.
407 MBMS conversation ends are represented after the MBMS business data transmission is finished, releasing network resources.
408 leave and add correspondingly with 403, and the expression user will leave a group, does not promptly rethink to receive certain professional data.
In order effectively to utilize Radio Resource, the radio-cell controller can be according to the channel type that how much decides that has the user in each sub-district.Preserve the critical value that channel type is changed in the radio-cell controller between point-to-point and point-to-multipoint.The number of users of subscribing to this MBMS business in the sub-district surpasses this critical value, and the radio-cell controller will be converted to point-to-multipoint with channel type, otherwise, then be point-to-point channel type.And the radio-cell controller only adds up those and is in the subscriber equipment of connection status when calculating number of users.That is to say that RNC can be retained in connection status with the state of some subscriber equipmenies, i.e. the PMM_CONNECTED state.Therefore for a business, always all will keep certain subscriber equipment in each sub-district is in the PMM_CONNECTED state to RNC.And subscriber equipment is in this state and just means that this subscriber equipment has radio resource control RRC and connects and to be connected with the Iu signaling.
When the MBMS service ending, when perhaps blanking time is long between two sessions that are close to or RNC when not having directly to receive the subscriber equipment of data down, SGSN or RNC can determine the Iu signaling of these these subscriber equipmenies connected to be connected with RRC to discharge, and make these subscriber equipmenies be in the PMM_IDLE state.Yet in the prior art, connect, just have only a kind of method: i.e. dismounting one by one with regard to the Iu signaling of how to remove user equipment specific.As shown in Figure 2, when SGSN required to remove the Iu signaling connection of subscriber equipment, it just sends to RNC, and " Iu discharged request information.After RNC receives this message, just discharge, return " Iu discharges and finishes " message to SGSN then connecting all relevant resources with this signaling.SGSN receives the SCCP (hereinafter to be referred as the SCCP connection) of just initiatively removing bottom after this message.Certainly this Iu connection discharges and also may be initiated by RNC.If like this, just " Iu discharges request information to RNC, and the Iu signaling that request SGSN removes this subscriber equipment connects to the SGSN transmission earlier.If SGSN agrees to remove, it is consistent that so ensuing process is just initiated Iu release with SGSN.Because one the connection of the signaling of special use is exactly the connection of a SCCP in fact.Therefore after Signalling exchange was finished, the dismounting of SCCP will be finished by SCCP.From 205 and 206 as can be seen, SGSN sends SCCP order " releases " to RNC, and RNC returns SCCP order " release is finished " then, thereby finishes the dispose procedure of Iu signaling connection.
Simultaneously in the prior art, when the MBMS business is provided, between RNC and SGSN, there is one to be connected at a certain professional professional Iu signaling of setting up.This signaling is connected to the signaling bear passage that the signaling relevant with business provides bottom.The dismounting that this signaling connects can connect dismounting mode unanimity with traditional signaling: promptly the signaling procedure with Fig. 2 description is the same.
Foregoing scheme can be finished the release of the signaling connection of MBMS subscriber equipment, yet whole dispose procedure consumed time is long, and the signaling load is heavy, and causes the waste to resource easily.

When conversation end or service ending, SGSN receives the conversation end indication of transmitting from GGSN, and it is transmitted to RNC.SGSN sends " conversation end " message 101 to RNC, may comprise " discharging indication " in this message.Showed that user's special use connected and can discharge if should " discharge indication ", RNC may initiate 103 " Iu discharges request " so subsequently.Otherwise the signaling that RNC also can continue to keep the MBMS business connects and is connected with the signaling of these subscriber equipmenies.It may be because the interval between the session is too short that SGSN do not allow these signalings to connect to discharge.If service ending, SGSN should allow traffic signaling to connect the release that is connected with user equipment specific.
If all subscriber equipmenies that is in connection status have all moved under other the RNC under the 102RNC, this just means that this RNC does not provide transfer of data to these subscriber equipmenies.If the resource anxiety of RNC, perhaps because the reason of other RRMs, may determine the signaling that discharges these subscriber equipmenies to connect, RNC can initiate " Iu discharges request " so, tells SGSN that it wants that the dedicated signaling that discharges certain user's equipment connects.Certainly the RNC signaling that also can discharge at this MBMS business connects, and release cause can be " not having subscriber equipment " etc." sign of subscriber equipment or corresponding signaling connection identifier " and " professional Iu release cause " that RNC will want to discharge are included in 103 message.
When SGSN receives 103 " Iu discharges request ", SGSN will check the subscriber equipment that comprises in this message whether not have other business, if do not have, shows that so the dedicated signaling of this subscriber equipment connects and can remove.It can comprise the sign or the corresponding signaling connection identifier of these subscriber equipmenies in 104 " Iu release commands ".If SGSN finds these subscriber equipmenies and also has other business, in 104, just can not comprise the sign or the corresponding signaling connection identifier of these subscriber equipmenies so.Also discharge if the RNC request connects this MBMS traffic signaling, SGSN can check the reason that the RNC request discharges.If because do not have subscriber equipment under this RNC, SGSN can discharge this traffic signaling connection so, sends 104 " Iu release commands " to RNC, and this message comprises parameter " release cause ", and indication RNC can discharge this traffic signaling and connect.If SGSN disagrees with this traffic signaling connection is discharged, so just can not comprise parameter " release cause ".
When RNC receives 104 " Iu release commands ", check the parameter of carrying in this message.If wherein comprise " customer equipment identification tabulation or corresponding signaling connection identifier ", show that so SGSN agrees the dedicated signaling of these subscriber equipmenies is connected dismounting.RNC just discharges with all resources this signaling join dependency this UE.If wherein also carry " release cause ", show that SGSN agrees this traffic signaling connection is also discharged, RNC returns 106 " Iu discharges and finishes " message to SGSN then with regard to the resource of dismounting with this traffic signaling join dependency so.Simultaneously RNC sends " signaling connect discharge " message to removing the subscriber equipment that dedicated signaling connects, and informs that its signaling that is connected with SGSN of these subscriber equipmenies is connected to remove.
After SGSN receives 106 " Iu discharges and finishes " message, just require bottom SCCP layer to remove relevant traffic signaling connection and be connected with the user equipment specific signaling.The release that SCCP connects can be finished by 107 and 108.
