Description
Technical field
The present invention relates to the multimedia broadcasting and the multicast service (hereinafter to be referred as MBMS) of point-to-multipoint, relate more specifically to the method for service wireless network controller on the Iur interface (hereinafter to be referred as SRNC) to floating radio network controller (hereinafter to be referred as DRNC) inquiry specific cell MBMS channel type.
Background technology
Multimedia broadcasting and multicast service (hereinafter to be referred as MBMS) are to propose also carrying out a standardized new business by third generation partnership project (hereinafter to be referred as 3GPP).The MBMS business is a kind of business of descending point-to-multipoint, and the maximum characteristics of this business are that it can effectively utilize Radio Resource and Internet resources.
In order better invention to be described, Fig. 1 has at first described the system configuration of MBMS.
Be description below to Fig. 1 MBMS system configuration:
The MBMS network configuration is based on GPRS (hereinafter to be referred as GPRS) core net, and increased new network element.101 broadcasting and multicast service center (hereinafter to be referred as BM-SC) are the professional control centres of MBMS system.102 Gateway GPRS Support Nodes (hereinafter to be referred as GGSN) and 103 Serving GPRS Support Nodes (hereinafter to be referred as SGSN) have constituted the transmission network of MBMS business, for the transmission of MBMS data provides route.107 attaching position registers (hereinafter to be referred as HLR) are the databases of preserving user profile, and services such as subscription authentication, location registers can be provided.104 SRNS Serving Radio Network Subsystems (being called for short SRNS) provide Radio Resource, SRNS to comprise service wireless network controller (hereinafter to be referred as SRNC) and base station (hereinafter to be referred as Node B) two parts for MBMS serves on the interface aloft.105 drifting radio network subsystems (hereinafter to be referred as DRNS) are for UE provides Radio Resource, and are similar to SRNS, and DRNS comprises floating radio network controller (hereinafter to be referred as DRNC) and base station (hereinafter to be referred as Node B) two parts.The 106th, subscriber equipment (hereinafter to be referred as UE) is the terminal that the user obtains network data and communicates.When UE simultaneously when SRNS and DRNS receive data, UE is in macro diversity status.
108 Iu represent the interface between wireless access network and the core net.110 Iur are the interfaces between SRNS and the DRNS.109 Uu are air interfaces, are also referred to as wave point.When being in macro diversity status, UE receives data from SRNS and DRNS on the interface aloft simultaneously.Data on the DRNS obtain to send on the air interface again then from SRNS by 110 Iur interfaces.
Effectively utilizing Radio Resource is the maximum characteristics of MBMS business.In order better to realize being optimized this target to air interface.With traditional professional different be, the MBMS business is a kind of business of point-to-multipoint, and network only sends a piece of data, and different users goes to receive.Transmission to traditional business is all undertaken by dedicated channel, and need be undertaken by common channel the transmission of the professional point-to-multipoint of MBMS.But when number of users more after a little while, use dedicated channel on the contrary than with the more effective save radio resources of common channel.Therefore, before providing the MBMS business to the user, SRNC must at first add up the number of users of each sub-district, and decision adopts point-to-point dedicated channel (hereinafter to be referred as the PTP mode) still to adopt the common channel (hereinafter to be referred as the PTM mode) of point-to-multipoint then.
The business characteristic current according to UE, UE can be in following 4 kinds of states, i.e. URA_PCH, CELL_PCH, CELL_FACH, CELL_DCH.Under URA_PCH and CELL_PCH state, UE only kept with being connected of network can not carry out transfer of data; Under the CELL_FACH state, UE takies public resource, can carry out the transfer of data of a small amount of low rate; Under CELL_DCH, UE takies private resource, can carry out the high-quality voice-and-data transmission of two-forty.
When UE at URA_PCH, in CELL_PCH and CELL_FACH state following time,, UE only keeps in touch with a specific sub-district, when receiving MBMS when professional, UE also only receives data from this specific sub-district, when SRNC adds up the UE of these states also than being easier to.As UE during, two sub-states are arranged at the CELL_DCH state: single cell status and macro diversity status, under single cell status, only keep in touch among the UE with a sub-district, at this moment UE receives the MBMS data and do not have essential distinction under other state; But under macro diversity status, UE is in the edge of sub-district, and UE keeps in touch with a plurality of sub-districts simultaneously, and these sub-districts are called as Active Set.When SRNC provides MBMS professional for being in UE under the macro diversity status, should at first investigate the channel type that adopt the sub-district in the Active Set of this UE, specify then UE from which sub-district with which kind of channel reception MBMS business.Under macro diversity mode, UE has only a SRNC, is in the sub-district that belongs to other radio network controller (RNC) but work as UE, and UE has just had a plurality of DRNC.When SRNC went for the used channel type in the sub-district of DRNC, SRNC will inquire about to DRNC by the Iur interface.
According to the definition of existing MBMS business, a MBMS business (service) can be made up of several sessions (session).For each session, when session begins, network can wake UE up and add up the UE number by paging, decision radio bearer type (radio bearer of point-to-point radio bearer or point-to-multipoint) and relevant parameter, UE only need listen to control channel in current area, with the information of obtaining data channel and receive data channel.But as previously mentioned, when UE was in grand diversity CELL_DCH state, UE kept in touch with a plurality of sub-districts simultaneously, does not have the indication of SRNC, and UE can't determine to receive in which sub-district the MBMS business.And SRNC will determine that UE receives the used channel type information in sub-district in the Active Set that number just must at first obtain this UE in which sub-district, just can make a policy then.
When communicating under UE is in macro diversity mode, it is kept in touch with a plurality of sub-districts simultaneously, and the Active Set of this UE is formed in these sub-districts.Consider the MBMS business, each sub-district all provides professional according to its number of users decision with the user which kind of MBMS is carried as this sub-district.Therefore both made for same MBMS business, a plurality of sub-districts in the Active Set of a UE may adopt different bearing mode (PTP or PTM) that MBMS is provided business.At this moment UE can't learn how to go to receive the MBMS business, can only make judgement and notice UE by SRNC.
SRNC makes judgement should be according to the used MBMS channel type in the sub-district in the UE Active Set, so SRNC should at first obtain the information of these channel types.For the home cell that SRNC managed, SRNC can directly obtain the information of this respect, and for the sub-district under other RNC, SRNC must obtain these information by Iur.
In existing protocol,, stipulated the MBMS connection procedure in order to support the mobility of UE.By this process, can be connected to a UE among the DRNC, DRNC responds corresponding beared information to SRNC simultaneously.But for grand diversity CELL_DCH UE, SRNC will at first recognize the used channel type in sub-district in the activation, makes judgement then.Before making decision, this UE can not be connected to sub-district in the Active Set.Therefore need improve existing connection procedure.
In the prior art, can switching system information between two RNC, support the professional needed function of MBMS but can't finish, therefore also need to design the inquiry that new flow process is finished the MBMS channel information.
Summary of the invention
The problem that exists at prior art, and MBMS business features, the present invention proposes SRNC to the method for DRNC inquiry MBMS channel type with determine to provide the method for MBMS business to being in UE under the macro diversity status.
A kind of SRNC provided by the invention may further comprise the steps to the method for DRNC inquiry MBMS channel type:
A) when SRNC need inquire about the MBMS channel type of the sub-district under the DRNC by the Iur interface, SRNC sends " MBMS channel type query requests " message to DRNC, and described " MBMS channel type query requests " message comprises the sign of the business that will inquire about and the sign of sub-district;
B) after DRNC receives described " MBMS channel type query requests " message, record sends the SRNC of described " MBMS channel type query requests " message and writes down the sign of the business that described SRNC will inquire about and the sign of sub-district, DRNC sends to SRNC to " MBMS channel type inquiry response " message then, described " MBMS channel type inquiry response " message comprises Cell Identity CI, radio bearer type and relevant parameter, radio bearer type comprises the cell MBMS channel type;
