Description
Technical field
The present invention relates to the resource distribution technology in the mobile communication system, particularly relate to multimedia broadcast/group broadcast service (Multimedia Broadcast/Multicast Service, the resource allocation method during MBMS) with conventional service concurrence.
Background technology
MBMS is the descending multimedia service of realizing on Packet Based Network basis, Packet Service (PS) territory that defines among the 3GPP R6, is a kind of standard of mobile phone TV services.MBMS is a kind of broadcasting service, and same business tine is broadcasting simultaneously in service area (generally comprising a plurality of sub-districts), like this, when move a plurality of sub-districts of UE in service area, can receive incessantly.In order to guarantee the synchronous reception of MBMS business when the synchronous and UE of different districts broadcasting moves freely in service area, a plurality of sub-districts of MBMS business in a service area must take identical physical resource, comprise frequency, time slot and code channel.
Because the MBMS technology allows mobile phone when the non-MBMS business of activation promptly comprises the conventional business of speech business and Packet Service, can receive the MBMS business, therefore, will have multiple MBMS and conventional service concurrence scene in actual applications.
And for the mobile phone of present R4, R5 version, owing to do not possess the ability of supporting multicarrier, synchronization can only receive data on a carrier wave, therefore, if receive the data of different carrier, can only carry out at different time-gap, and must change frequency, finishing also needs to stablize the data (referring to the MBMS industry standard) that certain hour could correctly receive new frequency after frequency is changed.Like this, when two kinds of business are used different carrier resources, must use different and non-conterminous time interval resource, just will satisfy the requirement of alien frequencies, conversion frequency so that mobile phone can have ample time every time slot.As seen, under MBMS and conventional service concurrence scene, network side need do the best want concurrent MBMS and conventional professional channel configuration with frequently or alien frequencies on the carrier resource of time slot, to realize above-mentioned two kinds of business concurrent in the mobile phone side.
Dynamic channel allocation (DCA) technology is that existing system is the technology that conventional business adopts when carrying out resource distribution.This technology is the integrated information of utilizing in the system, and all resources in the system are implemented to distribute, managed and scheduling, to maximally utilise system resource and to guarantee link and the performance of system.A critical function of dynamic channel allocation just is to use reasonable method to select the frequency of sub-district, time interval resource, to carry out professional admittance.Its objective is the carrying of balanced each frequency, maximally utilise system resource.For conventional professional frequency, the time interval resource collocation method realized according to the DCA specification requirement under the non-concurrent scene, proposed multiple mature methods at present, enumerated two kinds of methods comparatively commonly used below: a kind of is frequency, the time slot priority approach that adopts configuration fixing.The priority of each frequency of sub-district, time slot is in advance at Operation and Maintenance interface (O﹠amp in this method; M) be configured in, when conventional service access, then preferential that priority is high frequency, time slot configuration are to this business that need insert; Another kind is based on the method for idle code channel number.This method sorts to all frequencies, time interval resource according to idle code channel number, idle code channel is many, the priority height of this frequency or time slot then, the preferential the highest resource of priority of selecting is configured, and that is to say that the maximum frequency of its idle code channel number of selection, time slot configuration are to this business that need insert.In the practical application, also have certain methods to be based on the distortion and the combination of above-mentioned two kinds of methods, enumerate no longer one by one here.
By above-mentioned analysis as can be known, under MBMS and conventional service concurrence scene, when network side carries out the resource distribution of frequency and time slot by concurrent business, need to consider two kinds of standards, that is: both needed to consider that same frequency or alien frequencies that the UE ability causes limited every time slot, simultaneously also need to consider the DCA specification requirement, to reach flexible control to system resource.For simplicity, unification is called concurrent UE capabilities limits standard with last standard in the literary composition, back one standard is called frequency/time slot choice criteria of DCA.
Having the resource allocation method that is applicable under the concurrent scene now is that two kinds of standard serial are considered, promptly considers a kind of standard earlier, and then considers another kind of standard on this basis again.That is to say, need the frequency by two-wheeled, the selection of time interval resource in the existing method.This method is normally considered the DCA specification requirement earlier, promptly satisfy the requirement of the carrying equilibrium of each frequency, carry out taking turns the selection of frequency, time slot, on this base station, consider two kinds of concurrent restrictions then again, promptly satisfied frequency together or alien frequencies carry out second and take turns frequency, time slot selection every the requirement of time slot; Perhaps, in contrast, promptly consider concurrent restriction earlier, consider the DCA specification requirement again.And when above-mentioned two kinds of standards can't be taken into account, then can only select one as the criterion of carrying out frequency, time slot selection, can not take all factors into consideration.In addition, this method can not be controlled the use of frequency, time interval resource according to the wireless environment of reality neatly to the control underaction of frequency, time slot.For example, two kinds of voice and packet data concurrent services are better with meeting frequently in some environment, and two kinds of voice and packet data concurrent service alien frequencies can be better every time slot in some environment, and said method then can't satisfy the demand under these different application environment neatly.
This shows that the existing resource allocation method that is applicable under the concurrent scene can't really be realized the taking all factors into consideration of service concurrence restriction and DCA specification requirement, and can't control flexibly the use of system's frequency and time interval resource according to actual needs.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of resource allocation method.
