By adopting the invention, users without MCCH monitoring capacity in the cell private channel mode can obtain complete MBMS information so as to ensure that the users can use the expected MBMS, thus realizing network resource sharing and improving the utilization rate of the network resources at the same time.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of in CDMA (code division multiple access) mobile communication system, send the method for MBMS (Multimedia Broadcast/Multicast Service, multimedia broadcast-multicast service) notice to the user who is in CELL_DCH (cell private channel) pattern.
Background technology
MBMS is a kind of shared network resource, transmits the technology of data to a plurality of targets from a data source.In order to effectively utilize mobile network resource, 3GPP (the 3rd generation partner project agreement) has proposed the MBMS business in R6, promptly in the mobile network, provide a data source to send the point-to-multipoint service of data to a plurality of users, the realization Internet resources are shared, improve utilization rate of network resource, especially Bao Gui air interface resource.MBMS can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and multiple rich video, audio frequency and multimedia service are provided, for the development of mobile communication provides better professional prospect.
The structural model figure of MBMS operation system as shown in Figure 1, broadcast multicast service center BM-SC is newly-increased mobile network functional entity, it is content provider's a inlet, be used for authorizing and initiating the MBMS bearer service at mobile network, and plan transmits the MBMS content to schedule.To existing WCDMA Packet Based Network functional entity: GGSN (General Packet RadioService Gateway Support Node, gateway GPRS supporting node (GGSN)), SGSN (Serving General Packet Radio Service Support Node, service universal grouping wireless business supporting node), RAN (Radio Access Net, wireless access network) and UE (UserEquipment, subscriber equipment), also need to increase MBMS correlation function and process.
MBMS has introduced new logic channel: MCCH (MBMSpoint-to-multipoint Control Channel in RAN, the MBMS point is to the multiple spot control channel), be used for sending MBMS business control informations such as service announcements, radio bearer to all UE of sub-district; MTCH (MBMS point-to-multipoint Traffic Channel, MBMS point-to-multipoint service channel) is used for sending the MBMS business datum to all UE of sub-district.The MBMS business has two kinds of send mode: PTP (point to point, point-to-point) and PTM (pointto multipoint puts multiple spot) in RAN.By DTCH (Dedicated TrafficChannel, Dedicated Traffic Channel) transmission data, monopolized under the PTP transmission means by a UE; By MTCH (common logical) transmission data, shared under the PTM mode by a plurality of UE.After the professional beginning of MBMS, radio network controller sends the control informations such as service announcements, send mode, RB configuration of MBMS by MCCH channel all UE in the sub-district, whether revise according to business information, the business control information of the last transmission of MCCH is divided into has the MBMS of modification business information and unmodified MBMS business information two parts to send.Wherein, there is the MBMS business information of modification to send earlier, comprises the business information message MBMS MODIFIED SERVICESINFORMATION that MBMS revises, and other message of carrying the information such as radio bearer of the business that comprises in this message; Do not send after having the MBMS business information of revising, comprise the business information message MBMS UNMODIFIED SERVICES INFORMATION that MBMS is unmodified, and other message of carrying the information such as radio bearer of the business that comprises in this message.UE carries out corresponding flow process and receives the MBMS business get access to the MBMS business information of expectation reception from the MBMS business control information of MCCH after.
According to the 3GPP agreement, if the professional sending mode of the MBMS of RNC indication is PTP, must move into CELL_DCH pattern and set up special-purpose Traffic Channel of UE then from DTCH reception MBMS business; If the professional sending mode of the MBMS of RNC indication is PTM, then UE receives the MBMS business from MTCH, and this moment, UE can be IDLE, URA_PCH, CELL_PCH, CELL_FACH or CELL_DCH in any pattern.The UE of CELL_DCH need monitor DCCH (Dedicated Control Channel, Dedicated Control Channel) and receive dedicated control information, if use other non-MBMS business, also must use DTCH to carry.If UE will receive the MBMS business of PTM pattern in the CELL_DCH pattern, must possess the ability of monitoring common signal channels such as MCCH, MTCH in the CELL_DCH pattern, but this ability is not the universal demand to UE, and the UE that promptly has can only could monitor MCCH, MTCH under IDLE, URA_PCH, CELL_PCH or CELL_FACH pattern.Like this, the UE that can not monitor MCCH in the CELL_DCH pattern just can't obtain the MBMS business information that provides the sub-district from MCCH, thereby can't use the MBMS business.For this reason, 3GPP requires MBMS MODIFIED SERVICES INFORMATION message except sending on MCCH, also need on DCCH, send, can receive the MBMS business information of modification with the UE that guarantees no MCCH monitoring ability under the CELL_DCH pattern from DCCH at the UE of CELL_DCH pattern; But 3GPP requires simultaneously MBMSUNMODIFIED SERVICES INFORMATION message only to send on MCCH again, does not send on DCCH, like this, makes that the UE of no MCCH monitoring ability can't obtain unmodified MBMS business information under the CELL_DCH pattern.Detailed process is referring to Fig. 2, and step is as follows:
As from the foregoing, there is following problem in prior art: only send the business information message MBMS MODIFIED SERVICES INFORMATION that MBMS revises to UE on DCCH, and do not send the unmodified business information message MBMS UNMODIFIEDSERVICES INFORMATION of MBMS, like this, the UE that makes no MCCH under the CELL_DCH pattern monitor ability can't obtain unmodified MBMS business information in the MBMS UNMODIFIED SERVICESINFORMATION message, thereby can't use unmodified MBMS business.
Summary of the invention
