Technical field
The present invention relates to wireless communication field, particularly relate to a kind of method and apparatus that the carrier resource of common signal channel is allocated.
Background technology
Carry out adding up post analysis in the historical data that 2G network is produced to find: only account for mobile communication signal and cover the indoor coverage of signal region of the gross area about 20%, occupy the total base station number of mobile communication about 25% base station, but create the business of mobile communication system all overlay areas total traffic 70%, as can be seen here, the quality of indoor coverage of signal network quality decides the success or failure of operator.
In the prior art, indoor coverage of signal technology mainly includes room subsystem, MDAS system (MutiserviceDistributedAccessSystem, multi-service digital distribution access system) and Femto base station.Wherein, signal is covered each room difficulty cause more greatly application to be obstructed owing to existing by room subsystem;MDAS system is not mated so that application cost is higher due to carrier capacity and base station transmitting power;Femto base station limits its application owing to having that neighboring interval handoff relation is complicated and mobility is bad, and the problem existed for indoor coverage of signal technology in prior art occurs in that a kind of cellular technology altogether, it is achieved indoor coverage of signal.
As it is shown in figure 1, be that prior art is total to cell topology schematic diagram.So-called community altogether refers to the multiple signal sending and receiving equipments on multiple different physics sites are combined into a logic district, in this logic district, i.e. dispose multiple Remote Radio Unit (RRU), and it is divided into different RRU set of locations according to the position relationship of the multiple RRU disposed in this logic district, utilize the RRU set of locations after dividing to service for the terminal accessed.
There is advantages below in this common cellular technology: the first, realizes RRU position group and cover the signal of a logic district, decrease logic district quantity, simplify neighboring BS relationship;The second, when disposing, it is possible to ensure to mate between RRU set of locations signal transmission power and carrier capacity, and utilize common signal channel to realize terminal mobile management between diverse location group.
Specifically, as in figure 2 it is shown, be the distribution schematic diagram of carrier resource in a logic district in prior art.Assume that this logic district channel capacity is to support that (one is the carrier resource C0 of common signal channel for 9 carrier resources, other are carrier resource C1~C8 of Traffic Channel of RRU set of locations), 8 RRU set of locations (i.e. RRU set of locations 0, RRU set of locations 1, RRU set of locations 2, RRU set of locations 3, RRU set of locations 4, RRU set of locations 5, RRU set of locations 6 and RRU set of locations 7) are deployed in this logic district, now, the carrier resource of the common signal channel of RRU set of locations 0 is C0, and the carrier resource of Traffic Channel is C1;The carrier resource of the common signal channel of RRU set of locations 1 is C0, and the carrier resource of Traffic Channel is C2;The carrier resource of the common signal channel of RRU set of locations 2 is C0, and the carrier resource of Traffic Channel is C3;……;The carrier resource of the common signal channel of RRU set of locations 7 is C0, and the carrier resource of Traffic Channel is C8.
As can be seen here, all RRU set of locations in this logic district are used in conjunction with the carrier resource C0 of a common signal channel.
As it is shown on figure 3, the schematic diagram of mobile management when switching between different RRU set of locations for terminal.Assume that terminal switches to RRU set of locations 1 from RRU set of locations 0, this terminal is serviced for it by the channel 3 in proprietary carrier wave C1 in RRU set of locations 0, between base station triggers terminal position group after switching, in community, the idle channel 7 of common signal channel C0 services for it altogether, when base station side detects that terminal the most stably resides in RRU set of locations 1, now the channel 5 in the proprietary carrier wave C2 of distribution RRU set of locations 1 is serviced for it, successfully utilize publicly-owned carrier channel as the excessive resources of mobile management between set of locations, it is achieved terminal switching between diverse location group.
But, along with the increase of number of users in the signal cover of logic district, need the RRU set of locations quantity disposed in this logic district to increase the most therewith, the frequency that mobile terminal switches between RRU set of locations simultaneously increases therewith.Owing between RRU set of locations, the carrier capacity of common signal channel is certain, so, when great amount of terminals needs to switch request within a certain period of time between RRU set of locations, the carrier capacity that will appear from common signal channel cannot meet the demand of terminal, cause terminal that problems such as going offline occurs in process of service execution so that the business execution efficiency of this logic district reduces.

It should be noted that can also is that other modes in the mode that multiple set of locations of logical services Intra-cell administration are carried out multidomain treat-ment, it is not described in detail here.
Step 102: utilize the mode of space division multiplexing broadcast frequency, be respectively allocated the carrier resource of common signal channel for the described N number of sub-services community obtained.
Wherein, the carrier resource of the common signal channel being positioned at the set of locations configuration of same sub-services community is identical, and the carrier resource of the common signal channel being positioned at the set of locations configuration of different sub-services community is different.
Specifically, in a step 102, in the mode of described space division multiplexing broadcast frequency refers to same logic district, different sub-services minizones utilize the space isolation between sub-services cell coverage area to carry out frequency spatial separation, and the broadcast frequency of logic district be configured to same logic district in different sub-services community, each sub-services community carries the carrier resource of the common signal channel of each sub-services community on this broadcast frequency respectively.
Specifically, after obtaining N number of sub-services community, carrier resource information space division multiplexing N part of the common signal channel of this logical services community will be allocated to, it is respectively allocated to the N number of sub-services community obtained, wherein, each sub-services community has the carrier resource of an independent common signal channel, and the carrier resource capacity of the common signal channel of single sub-services community is identical with the carrier capacity of the common signal channel being allocated to original logical services community.
As it is shown in figure 5, be the distribution schematic diagram of carrier resource frequency point information in a logic district.Assume this logic district channel capacity for support 10 carrier resources (wherein, first be the carrier resource of common signal channel be C0, second be the carrier resource of common signal channel be C0/Other carrier resources are the carrier resource of the Traffic Channel of set of locations: C1~C8), 8 set of locations (i.e. set of locations 0, set of locations 1, set of locations 2, set of locations 3, set of locations 4, set of locations 5, set of locations 6 and set of locations 7) are deployed in this logic district, wherein, set of locations 0, set of locations 1, set of locations 2, set of locations 3 belong to a sub-Serving cell, and set of locations 4, set of locations 5, set of locations 6 and set of locations 7 belong to another sub-services community.
The mode of the carrier resource so distributing common signal channel includes but not limited to:
