Description
Technical field
The present invention relates to a kind of in wireless communication field TD-SCDMA (TD SDMA access) system multi-carrier frequency cell be the method and apparatus of MBMS (multi-medium multi-packet broadcasting) traffic assignments Radio Resource, relate in particular to a kind of method and apparatus of multimedia broadcast multi-broadcasting business distributing radio resource that is.
Background technology
In order to satisfy the ever-increasing demand in mobile communication market, the power system capacity that improves hot zones covers, TD-SCDMA multi-carrier frequency cell notion is that a plurality of sub-districts of identical geographical coverage area (each carrier frequency is a sub-district) is merged together, share a cover common channel resources, thereby constitute a multi-carrier frequency cell, not only on RRM, reduced complexity, and the main carrier frequency of neighbor cell is configured on the different frequencies, not only can reduce the interference of pilot channel and common signal channel effectively, and can reduce requirement effectively, thereby can guarantee to carry out networking with flexible way more to the base station acc power.
Along with the commercialization of 3-G (Generation Three mobile communication system), mobile TV service (Mobile TV) more and more receives the concern of operator at present.In the TD-SCDMA system, provide multimedia broadcasting and multicast service (MBMS:Multimedia Broadcast/Multicast Service) also to become an active demand.Organize the agreement of 3GPP according to global standardsization to the MBMS business, the MBMS business is at UTRAN (Universal Terrestrial Radio Access Network, universal land radio access web) and UE (User Equipment, dual mode is arranged: PTM (Point-to-Multipoint when transmitting subscriber equipment), point-to-multipoint) mode and PTP (Point-to-Point, point-to-point) mode.The PTM mode uses common logical MTCH (MBMS PTM Traffic Channel, point multipoint message traffic channel) that all are added multicast service or the interested UE of broadcasting service is sent data; The PTP mode then uses dedicated logical channel DTCH that single UE is sent business datum.When adding multicast service or when big, using the PTM mode can effectively utilize wireless network resource undoubtedly, cut operating costs widely to the interested UE number of broadcasting service.
Can there be serious co-channel interference when in the TD-SCDMA multi-carrier frequency system, providing MBMS professional.Logic channel MTCH under the MBMS PTM mode is mapped to transmission channel FACH, and finally is carried on the SCCPCH public physic channel.Public physic channel SCCPCH uses omni-directional antenna transmission.While MBMS business is the mobile TV service of high speed normally, takies many code channels.Like this, when using the SCCPCH channel of omni-directional antenna transmission to carry out the continuous covering of MBMS business, can cause serious minizone co-channel interference, make service quality can not get ensureing in many sub-districts.
The problem of co-channel interference of minizone during for the solution identical networking, a kind of scheme are that all sub-districts use same carrier, time slot, channel code, scrambler and basic midamble code (midamble code) to send the wireless signal of identical MBMS business channels.Under above-mentioned pattern, UE can be considered as multipath signal with the signal that comes from different base station, makes to obtain big performance gain aspect the receiving broadcast service signal, has improved the service quality of MBMS business.This scheme can improve the broadcasting service availability of frequency spectrum, and the realization of UE side is also comparatively simple simultaneously.Usually, a MBMS business has a professional numbering, and an identical service area (SA:service area) numbering is used in the sub-district in the zone that this MBMS business is covered.To the MBMS business of given area numbering and professional numbering, identical Radio Resource is used in the sub-district that this scheme necessarily requires all to belong to this given area numbering, comprises frequency, time slot, channel code, scrambler and basic midamble code.So the independently dynamic resource allocation method of traditional cell-level based on sub-district physical resource situation just no longer is applicable to the MBMS business.
Under above-mentioned MBMS wireless signal sending mode,, need to revise the standard interface protocol between the radio network controller (RNC) that has 3GPP now if carry out fully dynamic allocation of radio resources for the MBMS business.If keep existing 3GPP agreement constant, then can only take static resource allocation method.In the resource allocation method of static state, if take Radio Resources such as professional numbering of MBMS and frequency, time slot form one to one, not only make universal land radio access web (UTRAN) be subject to very much the configuration of CN (core net), on wireless resource allocation, also seem very inflexible and inefficient simultaneously the MBMS business.Because MBMS business may have its specific broadcast time section, also only during session (session), just can take valuable Radio Resource simultaneously.The different sessions of a MBMS business may be used different RAB (RAB:radio access bearer) parameter (as maximum traffic rate) simultaneously.Existing technology can't provide not only unified but also flexible and efficient radio resource management method for the MBMS business.
