Description
Technical field
The present invention relates to the method that the Iu user plane discharges in Wideband Code Division Multiple Access (WCDMA) (hereinafter to be referred as the WCDMA) mobile communication system.
Background technology
Multimedia broadcasting and multicast service (hereinafter to be referred as MBMS) are that a standardized new business is being carried out in third generation partner plan (hereinafter to be referred as 3GPP).The MBMS business is a kind of business of unidirectional point-to-multipoint, and the maximum characteristics of this business are that it can effectively utilize Radio Resource and Internet resources.
Fig. 1 has described the system configuration of MBMS, and the MBMS network configuration is based on GPRS (be called for short GPRS) core net, and has increased new network element.Be description below to Fig. 1 MBMS system configuration.
101 broadcasting and multicast service center (being called for short BM-SC) are the professional control centres of MBMS system.102 Gateway GPRS Support Nodes (be called for short GGSN) and 103 Serving GPRS Support Nodes (abbreviation SGSN) have constituted the transmission network of MBMS business, for the transmission of data provides route.104UMTS land radio access web (being called for short UTRAN) provides Radio Resource for MBMS serves on the interface aloft.105 subscriber equipmenies (being called for short UE) are the terminal equipments that is used for receiving data.106 attaching position registers (being called for short HLR) are preserved and subscriber-related data, and services such as subscription authentication can be provided.107Uu is a wave point, and 108Iu represents the interface between Access Network and the core net.Among the figure, the other parts formation base domain except that UE (being called for short IF).The professional used Radio Resource of MBMS is not user's special use, but professional thus all users share.
The foundation of MBMS Iu interface user plane at present can have two kinds of methods.When having the user will receive the MBMS business below the RNC, first method:
401 RNC can send " MBMS service request " message and give SGSN;
" MBMS RAB sets up request information and gives RNC in 402 SGSN transmission;
403 RNC send " MBMS RAB sets up response " message and give SGSN;
Perhaps:
" the MBMS user plane is set up request information and is given SGSN in 501 RNC transmission;
502 SGSN send " the MBMS user plane is set up response " message and give RNC.
When not having the user below the RNC from then on the Iu user plane between RNC and the CN receives data, RNC can send message to CN (among Fig. 2 shown in 201 steps), hangs up the user plane of this Iu interface.SGSN temporarily stops this RNC is sent data.The Iu interface receives the MBMS data up to there being the user to need from then on, and RNC sends message again to CN (among Fig. 2 shown in 201), removes the suspended state of this Iu interface, and from then on SGSN begins to transmit data to RNC on the Iu interface.
In the time of the MBMS service ending, when perhaps the MBMS business has a very long time not have data, can initiate " traffic segment end " (session stop) message by CN and give RNC (among Fig. 3 shown in 301), discharge the resource of Iu interface.
Up to now, a kind of situation below present standard does not also have to consider: the user plane on the Iu interface is suspended, long-time not use, and business does not stop, if keep this user plane always, then the resource to the Iu interface is a kind of waste.How to discharge the user-plane resources of Iu interface, in current system, do not address this problem.
Summary of the invention
The method for releasing that the purpose of this invention is to provide a kind of Iu interface user plane.The method can effectively be utilized the resource of Iu interface, discharges otiose Iu interface user plane.Also do not finish in the MBMS business, do not discharge this Iu user plane under user's Iu user plane reception from then on data conditions if having.
According to an aspect of of the present present invention, the method that a kind of WCDMA Iu interface user plane resource discharges comprises step:
1) initiate the Iu user-plane resources by RNC and discharge, " the MBMS user plane discharges request information and gives SGSN in transmission;
2) SGSN sends " the MBMS user plane discharges response " message and gives RNC, finishes the release of user-plane resources.
According to another aspect of the present invention, the method that a kind of WCDMA Iu interface user plane resource discharges comprises step:
1) initiate the Iu user-plane resources by SGSN and discharge, SGSN sends ' the MBMS user plane discharges request ' message and gives RNC, and request discharges the user plane of the Iu interface of MBMS;
2) RNC sends response message to SGSN, and RNC sends ' the MBMS user plane discharges response ' message and gives SGSN, discharges the user plane of the Iu interface of MBMS.

Embodiment
(1) in order effectively to safeguard the Iu interface user plane, discharge otiose Iu interface user plane, the present invention proposes the method for releasing of initiatively initiating MBMS Iu interface user plane by RNC." user plane discharges request information and gives SGSN, requires to discharge user-plane resources in the RNC transmission.Comprise the MBMS service identification in this message, the reason that the Iu user plane discharges, reason can be " not having the user to use " or " overtime ".
RNC can initiatively initiate the method for releasing of Iu user plane, can be applied to three kinds of following situations.
First kind of situation, the user who receives the MBMS business below the SRNC moves to the sub-district below the DRNC, and this user is first user under the DRNC, this DRNC will send message to SGSN, user plane is set up in requirement, and DRNC tells SGSN, and this user plane is to use in the future.After user plane was set up successfully, RNC started a timer or clock, and time span is by can be by Operation and Maintenance (O﹠amp; M) be provided with.When timer be 0 or clock surpassed threshold value, initiate the process that the Iu user plane discharges by RNC, send that " the MBMS user plane discharges request information and gives SGSN.
