Abstract
The invention discloses a switching method and a system of the transmission mode from PTP to PTM. The method comprises the following processing that a RNC judges whether the transmission mode switch from PTP to PTM is necessary in an nth modification cycle and establishes a PTM RB; the RNC sets the action of the UE corresponding to the service to be acquiring the PTMRB information in an n+1th cycle and transmits the PTM RB information to the UE; the RNC transmits the RB release information to the UE; the UE releases the PTP RB and establishes PTM RB according to the PTM RB information transmitted by the RNC. With the invention, the MBMS services could be switched from the transmission mode of PTP to PTM and the process of UE releasing the PTP RB is effectively controlled to establish the PTM RB and receive the MBMS transmitted in the mode of PTM.
Description
Technical field
The present invention relates to the communications field, particularly, relate to Wideband Code Division Multiple Access (WCDMA) (WidebandCode Division Multiple Access, WCDMA) in the mobile communication system, multimedia broadcast/group broadcast service (Multimedia Broadcast/Multicast Service, MBMS) (point to point is PTP) to putting multiple spot (point to multipoint, PTM) changing method of send mode for point-to-point.
Background technology
Multimedia broadcast/group broadcast service (MBMS) is a kind of shared network resource transmits data to a plurality of targets from a data source a technology.In traditional mobile network, cell broadcaste service (Cell Broadcast Service, CBS) allowing low bit rate data to share broadcast channel by the sub-district sends to all users, belong to information series business, (Short Message Service, SMS) cell broadcaste service uses CBS to have only short message service in R99.
In order to effectively utilize mobile network resource, 3GPP has proposed MBMS in R6, MBMS provides a data source to send the point-to-multipoint service of data to a plurality of users in the mobile network, it has realized that Internet resources are shared, has improved the especially utilance of valuable air interface resource of Internet resources.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, multiple rich video, audio frequency and multimedia service are provided, this has complied with the trend of following mobile data development undoubtedly, for the development of 3G provides more wide professional prospect.
Broadcast multicast service center (Broadcast/Multicast Service Centre, BM-SC) be 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: gateway GPRS supporting node (GGSN) (General Packet Radio Service Gateway Support Node, GGSN), service universal grouping wireless business supporting node (Serving General PacketRadio Service Support Node, SGSN), wireless access network (Radio Access Net, RAN) and subscriber equipment (User Equipment, UE), also need to increase correlation function and the process of MBMS.
The MBMS business has two kinds of service bearing modes, that is, and and broadcast mode and multicast pattern.Multicast pattern needs user's corresponding multicast group of contracting, and carries out activation of service, and produces corresponding charge information.Because it is different that multicast pattern and broadcast mode exist, cause also difference of its operation flow on business demand.
In MBMS multicast service flow process, it is two independently processes that the user adds that multicast group and session begin, and promptly the user can be in the adding multicast group whenever in the middle of session begin to carry out with session.
The MBMS business has two kinds of send modes: point-to-point (point to point, PTP) and put multiple spot (point to multipoint, PTM).Pass through dedicated logical channel (Dedicated Traffic Channel under the PTP transmission means, DTCH) transmission data, be mapped to forward access channel (Forward Access Channel, FACH), dedicated channel (DedicatedChannel, DCH) or high speed descending sharing channel (High-Speed Downlink SharedChannel, HS-DSCH) on, have only a UE to receive; Transmit data by MBMS PTM (Multimedia Broadcast/Multicast Service point tomultipoint) Traffic Channel MTCH under the PTM mode, be mapped on the FACH, can receive by a plurality of UE.
Determine that at present send mode generally adopts the method for counting, when session begins, network side enabling counting process, the UE number of this MBMS business of reception adopts the PTP mode more after a little while in the sub-district, otherwise adopts the PTM mode.
Carry out in the process in session, if when having adopted the PTP mode to send, can also adopt the method for restatement number, the UE number that receives this MBMS business in the sub-district is transformed into the PTM mode by the PTP mode more for a long time, can effectively utilize resource like this.Detailed process can be with reference to Fig. 1.
At present, though to adopt PTM mode or PTP mode under which kind of situation, that is, the switching of when carrying out between the PTM/PTP is stipulated, but for how between the PTM/PTP mode, switching this problem but not relating to, not realizing technically yet.
Summary of the invention
Consider the problems referred to above that exist in the correlation technique and propose the present invention that for this reason, the present invention aims to provide a kind of changing method of transmission mode from point-to-multi-point to point-to-point and the system that implements described changing method is provided.
