Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
For solving the problem of prior art, the shared implementation method of a kind of channel processing resource based on unified channel model has been proposed in the embodiment of the present invention, by making, channel format is unified, handling process unified, timing is unified, improve parameter unification, makes between community, R99/HSDPA/HSUPA interchannel realizes shared resource pool and become a reality.
Unified channel model in the embodiment of the present invention can comprise: unified domain model, unified parameter model, unified transaction module and unified timing model.
Wherein, according to the definition of unified domain model, it is the Frame of unified frame format by the data-mapping of different channels type, according to the definition of unified timing model, the Frame of different channels type and community is carried out to timing unified, in unified transaction module, define unified modulation processing method, and adopted the parameter defining in unified parameter model to carry out above-mentioned processing.Make can adopt the downlink data of same processing Energy Resources Service's reason different channels type and community in the time that subsequent brew is processed.In the unified transaction module of broad sense, also comprise Frame processing and Timing Processing process.In the unified parameter model of broad sense, also define the parameter of Frame processing and Timing Processing.Below in conjunction with specific embodiment, above-mentioned model is described.
As shown in Figure 2, be an idiographic flow schematic diagram of the data modulation method in the embodiment of the present invention, the method can be used for, in the base station of UMTS, comprising the steps:
101, obtain and treat modulating data, described in treat that modulating data is downlink channel transmission data.This down channel can be various types of channels of existing definition in UMTS, as channels such as R99, HSDPA, HSUPA, and along with the development of UMTS technology, can also be the channel of following new definition.Also may be the channel of other communication systems.
102, treat the down channel type of modulating data or/and field parameter corresponding to community treats that to described modulating data carries out Frame mapping and processes according to described, obtain the Frame of unified frame format, the Frame of described unified frame format is defined as every frame n millisecond and comprises that m time slot or every subframe n/l millisecond comprise m/l time slot, each time slot comprises p data field at the most, wherein, n, m, l, p are predefined natural number.As, can set n and be 10, m and be 15,1 is that 5, p is 10.
Wherein, in described field parameter, described in definition, treat the down channel frame format of modulating data and the data-mapping relation of described unified frame format.; described unified frame format be have predetermined: the timeslot number that the length of Frame, every frame comprise, every time slot comprise the form of territory size and type, in field parameter, go back the dissimilar down channel frame format of definable UMTS and the mapping relations of described unified frame format simultaneously.Unify frame format or can be described as according to the frame format of unified domain model definition.
Wherein, unifying domain model may be defined as and have predefined frame length, every frame slot number, subframe lengths, the number in the territory of each time slot, the model of the length in each territory etc.As, it is 10 milliseconds (ms) that definable is unified every frame length in domain model, and every frame comprises 15 time slots (slot), or every subframe lengths is 2ms, and every subframe comprises 3 slot; Every slot comprises maximum 10 territories (field), and each length of field is 256 chips (chip).Wherein, in this example, chip refers to the chip of UMTS, is the minimum timing unit stipulating in UMTS agreement.
In the time of the unified domain model of definition, wherein the size in each territory is that base unit can be joined by symbol granularity, and each territory may be defined as the integral multiple of symbol granularity, and symbol granularity is 256chip, and the unit definition in territory is 256chip; The content in each territory can be joined,, the content in each territory can be configured to Types Below: data (data), discontinuous transmission interval (Discontinuous Transmission, DTX), control message (controlinformation, CI); The source in each territory can be joined, can define flexibly data in each territory from where (as, digital signal processor (DSP), internal memory (Memory) or upper level hardware accelerator etc. outside device) flexibility of obtaining to improve device; Algorithm operating can be independently carried out in each territory, as the power factor scheduling algorithm that multiplies each other.；
As shown in Figure 3, for the definition exemplary plot of the unified domain model in the embodiment of the present invention, in this example, Frame length is 10ms, each Frame has 15 slot, each slot has 10 field, each length of field is 256chip, and the type that defines the content in each territory can be: Data, DTX or CI.

As shown in Figure 9, for Node B frame number (NodeB FrameNumber, the BFN) timing of existing each community and NodeB differs T
cell(integral multiple that this difference is 256chip), and each physical channel and cell timing differ τ
chipoffsetthe graph of a relation of (this difference is also the integral multiple of 256chip).Each channel independently relatively the difference of BFN be:
