Description

Radio network controller is the method that portable terminal is set up radio bearer

Technical field

The present invention relates to field of mobile communication, particularly in code division multiple access (CDMA) system, a kind of radio network controller (RNC, Radio network controller) obtains the RAB (RAB that selects professional (selected service), and be the method that each portable terminal (UE) set up to be selected professional point-to-point wireless carrying Radio Access Bearer).

Background technology

Along with popularizing of large-screen multi-functional mobile phone, the application of mobile data services more and more widely, the demand of mobile communication no longer is satisfied with phone, message and surfing Internet with cell phone browse service, because the fast development of Internet, a large amount of multimedia services emerge.Various high bandwidth multimedia services such as video conference, television broadcasting, video request program, advertisement, online education, interactive game etc. constantly occur, satisfy the business demand that the mobile subscriber constantly rises on the one hand, also bring new business growth point simultaneously for mobile operator.These mobile multi-media services require a plurality of users can receive identical data simultaneously, compare with general data, have characteristics such as data volume is big, longer duration, delay sensitive.Present IP multicasting technology only is applicable to wired IP network, is not suitable for the mobile network, because the mobile network has particular network structure, functional entity and wave point, these are all different with wired IP network.

In order to effectively utilize mobile network resource, 3GPP has proposed multimedia broadcasting and multicast service (MBMS, Multimedia Broadcast Multicast Service), 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, the especially Bao Gui interface resource of eating dishes without rice or wine.The MBMS business is a kind of shared network resource transmits data to a plurality of targets from a data source a technology, the MBMS of 3GPP definition 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 better professional prospect.

The MBMS business comprises: multicast service (Multicast Service) and broadcasting service (Broadcast Service).Each multicast service all needs Joining (adding) process, user (UE) needs to BM-SC (BroadCast MultiCast Service center, Broadcast-MulticastService Centre) activate certain multicast service, and for each broadcasting service, UE only needs local activation just passable.In the configuration of radio bearer, multicast service can adopt the bearer types of P-T-M (put multiple spot, also can write a Chinese character in simplified form PTM or ptm) and P-T-P (point-to-point also can be write a Chinese character in simplified form PTP or ptp), and broadcasting service can only adopt P-T-M.

An important application type of service based on the MBMS technology is mobile TV (MobileTV over MBMS), be also referred to as mobile TV, can also comprise that in fact other are similarly professional, as: the music on the mobile phone, stock of mobile phone or the like, therefore in the present invention for convenience, make a general reference this class MBMS business with mobile TV and (moving) television channel.In order on mobile phone, to realize Mobile TV over MBMS business better, carried out for present 3GPP standard that some are perfect, be mainly used in solution: can reduce handover delay when the cellphone subscriber is switched different television channels and reduce activation of service time of different channel.

For this reason, as shown in Figure 1, in the present standard of 3GPP, MBMS is professional for being further divided into 2 kinds of types of service (Multicast Service Type and Broadcast ServiceType), 2 kinds of distribution modes (Multicast mode and Broadcast mode).All MBMS types of service that possess the characteristics of Multicast Service Type and Broadcast Mode Type are represented with selected service in the present invention, be called the business of selecting, also be mobile TV by general reference, each selects professional, and just each (moving) television channel identifies with a selected service ID.Mobile TV service does not need Joining (adding) process, only needs local activation, and possesses the radio bearer mode of P-T-P and P-T-M.

As shown in Figure 2, by receiving MBMS service statement (MBMSService Announcement) from network side, which MBMS business the user can select interested, if multicast service (Multicast Service), the user passes through adding (Joining) process subsequently, joins in this business.For multicast service, when the user adds a MBMS business, what UE distributed oneself sends to CN (core net) side with this professional corresponding NSAPI ID (Network ServiceAccess Point Identifier ID, Network Service Access Point Identifier) by activation.Set up request (MBMS ptp radio bearer request) if be in the UE response count (MBMS counting) or the response ptp carrying of idle pulley or CELL_PCH, CELL_FACH, URA_PCH, to set up RRC connects or cell update, UE sends business request information (Service Request) to CN then, sets up Iu and connects.When UE is setting up the Iu connection on the Iu interface after, on the Iu interface, by UE Linking process, CN sends to RNC with the professional pairing PtP RAB ID of the MBMS of these all addings of UE, each PtP RAB ID and a MBMS Service ID correspondence, the NSAPI ID of each PtP RAB ID and each this UE is corresponding.Therefore, the Service ID of the multicast service that adds at certain user, the UE side has been distributed a NSAPI ID and corresponding RAB ID, also obtains NSAPI ID and the RAB ID of identical this UE simultaneously at CN.

On the Iu interface, CN is by Session Start message, the relevant information of a MBMS business is sent to RNC, comprising the professional pairing RAB parameter of this MBMS, comprise type of service, maximum digit rate in the RAB parameter, guarantee digit rate or the like, be used for RNC and set up radio bearer (Radio Bearer) subsequently.For multicast service, RNC passes through counting process, if when a multicast service carrier is PtM, RNC is on MCCH, send " the public point to multi-point wireless beared information of MBMS " (MBMS COMMON P-T-M RBINFORMATION) and " MBMS current area P-T-M wireless loading information " (MBMS CURRENT P-T-M RB INFORMATION), the Service ID and the radio bearer configuration information that have comprised this multicast service in the message, transport channel configuration information and physical channel configuration information etc., added this professional UE and can on common signal channel, receive this MBMS multicast service according to the configuration information that comprises in the message that receives; When if RNC determines that by counting this multicast service carrier is PtP, RNC can further set up the RB (radio bearer) of this UE with the RAB ID of each UE that obtains from CN by the UElinking process at this MBMS service ID.

The problem that exists is at present: for selecting professional (being also referred to as mobile TV), in order to shorten the activationary time that each mobile television channel switches, in agreement, cancelled adition process, the CN side can't obtain reporting from UE with the corresponding NSAPI ID of each mobile television channel (selected service ID), do not had UE linking process on the Iu interface, RNC can't obtain and the corresponding RAB ID of each mobile television channel (selected service ID) from CN.Like this when the UE local activation behind certain television channel, RNC can't obtain the RAB ID at this selected service ID of this UE, when if RNC determines business with this selected service ID to be based upon the P-T-M carrying according to counting process, RNC is based upon common signal channel with this business, does not need the RAB ID of each UE; If when RNC determined business with this selected service ID to be based upon the P-T-P carrying according to counting process, RNC can't obtain the corresponding RAB ID of each UE, can't set up dedicated bearer.In a word, according to present agreement, because RNC does not know the RAB IDs (1 RAB ID is corresponding with 1 selected service ID) of each UE, so, mobile TV can only adopt the ptm transmission, be carried on the common signal channel, can not satisfy allowing mobile TV to be carried as the requirement of P-T-P and P-T-M in order effectively to utilize interface-free resources.
