Description
Technical field
The present invention relates to moving communicating field, implementation method and a kind of TD-SCDMA (TD SDMA) terminal that particularly a kind of non-transparent data traffic switches.
Background technology
The data service of circuit domain is mainly accomplished by terminal adapting function (TAF, Terminal Adaptation Function) module at mobile terminal side.The TAF module provides public land mobile network (PLMN; Public Land Mobile Network) network user and public switch telephone network (PSTN; Public Switched Telephone Network) network user, integrated services digital network (ISDN; Integrated Service Digital NeTwork) terminal adapting function of data service between the network user, its main task are carry on an agreement conversion and rate adapted.
The TAF module mainly is responsible for the processing of transparent service and non-transparent data traffic.In non-transparent data traffic, user side data is handled mainly and is responsible for by radio link protocol (RLP, Radio Link Protocol) unit and layer 2 relay (L2R, Layer 2 Relay) unit.L2R unit (being embodied as the L2R entity here) is used for segmentation and reconfigures the user profile data; Make user's information data be suitable for the transmission of radio channel; Transmit as the user profile data being fitted in the suitable R LP frame, the frame length of the RLP that L2R carries out when adaptive using according to current non-transparent data traffic carries out.The L2R unit is in upstream data is handled; From the transmit queue reading of data; Accomplish the framing of user data and filling in of state information; Pass to RLP unit (being embodied as the RLP entity here) through request of data (Data_Req) message, and under the management control of radio link protocol administrative unit (RLP_Mnanager), send to lower layer entities, and further be sent to network.In downlink data was handled, L2R received data through data indication (Data_ind) message from RLP, extracts state information, and is mutual with terminal equipment (TE, Terminal Equipment), and writes data to receiving formation.
It is state byte, information byte and byte of padding that the user profile data of L2R encapsulation are divided into 3 types.Wherein, 3 bits in the state byte are used to transmit flow-control information, and 5 bits are used for the presentation address type.The implication difference that the address style of different values is represented.The position of the position of next state byte apart from the present status byte represented in address style value 1～23 o'clock, promptly shows the byte number of the effective information byte that the message segment of this state byte sign comprises; During address style value 31, what expression finished from this state byte to message segment to fill all is slack byte; During address style value 30, it all is information byte that expression finishes from the state byte to the message segment; During address style value 29, the expression interrupt signal, all the other are slack bytes; During address style value 28, expression is to the affirmation of interrupt signal, and all the other are slack bytes; During address style value 27, the next byte of expression state byte is an address pointer, points out the position of next state byte, is used to identify the situation of two state byte distances greater than 23 bytes; Address style value 24～26 keeps.
Table 1 shows the frame structure of a L2R framing.Like table 1, this L2R framing comprises n byte, and wherein, first byte is that label is that 0 byte is a state byte, and back 3 bit SA, SB and the x of this state byte are used to transmit flow-control information, and preceding 5 bits are represented address style.The address style value is 3 (binary ones 1) in this state byte, and the position of representing next state byte is apart from 3 bytes of this state byte, and promptly the position of next state byte is the 5th byte (label is 4).The address style value is 31 (binary ones 1111) in the 5th byte, shows that promptly this state byte is last state byte, and what this state byte was filled to the end of message segment all is slack byte.
Table 1
The RLP module plays the data link layer protocol effect, and through frame check, sliding window technique is supported to retransmit and select re-transmission, guarantees the reliable transmission and the Flow Control of data.Stipulate among the 3GPP agreement TS24.022 that its RLP Frame length of different air traffic channel has two different editions: when the user adopts TCH/F4.8 and TCH/F9.6 channel, user's RLP Frame length position 240 bytes; When the user adopted TCH/F14.4, TCH/F28.8 and TCH/F43.2 channel, user RLP Frame length was 576 bytes.The frame type that RLP possibly send is divided into U frame, S frame and S+I frame, and every kind of frame is divided into frame head, information and FCS check field three parts.The content of L2R framing leaves the message segment of RLP in, so the length information of L2R framing is long closely related with rlp frame.
In the cell mobile communication systems; The limited coverage area of single base station; So, when user terminal gets into the another one sub-district from sub-district in the process of conversation, in order to guarantee communication continuity; System will transfer to this user terminal and getting in touch of original sub-district foundation on the new sub-district, and Here it is, and switch the sub-district.User terminal not only can switch between the different districts under the same base station controller, but also can on different system, different base station controller, switch.In realizing process of the present invention; The inventor finds that the mobile subscriber may switch in the process of carrying out non-transparent data traffic; For the switching between different system, different base station, the type of the Traffic Channel (TCH, Traffic Channel) that the user adopts before and after switching is inequality possibly; For example switch to the 2G system from the 3G system; The type of the TCH channel that 3G system and 2G system are supported is inequality, for example switches to the TCH/F9.6 channel from the TCH/F14.4 channel, and the frame length of rlp frame can be because air traffic channel be different and inequality before and after switching with form; The frame length of RLP is 576 under the TCH/F14.4 channel, and the frame length of RLP is 240 under the TCH/F9.6 channel.When the TCH channel changed, RLP can trigger again adaptive flow process, REMAP process just, purpose be for the RLP of network new once transformat synchronously, REMAP process success back RLP just carries out the transmission of data according to the frame format after the switching.In prior art such as the agreement REMAP flow process of carrying out between RLP and the network side is described, but prior art does not provide a kind of when RLP triggers the REMAP flow process, consider that the method that non-transparent data traffic switches is realized at the TD-SCDMA terminal of L2R.
