Description
Technical field
The present invention relates to the method for designing of random access procedure in a kind of wireless communication system, relate in particular to the method for designing that the terminal wireless access capability information transmits in a kind of random access procedure.
Background technology
The terminal wireless access capability information has been described the concrete ability of terminal access to wireless communication system and the concrete ability that uses the wireless communication system Radio Resource.Different terminals can possess different terminal wireless access capabilities, and Access Network is its configuration of selecting suitable wireless access way and using Radio Resource according to the qualification of terminal wireless access capability.
The terminal wireless access capability information can be with incompatible expression of concrete parameter set of representing this terminal wireless access capability, also can gather with the classification of the category division of this terminal wireless access capability and represent.The terminal wireless access capability information comprises:

Other ability parameter or classification: the concrete ability situation of having described other ability of not putting into above classification in the terminal wireless access capability (as support situation of the special characteristic of special agreement version of terminal etc.).
In the wireless communication system, the random access procedure of prior art as shown in Figure 1, concrete steps are as follows:
1) terminal sends " the Radio Resource control connection is set up request " signaling and gives Access Network on Random Access Channel, and request inserts;
2) Access Network sends " foundation of Radio Resource control connection " signaling and gives terminal on forward access channel, confirm to allow terminal to insert, and terminal inserts in which way;
3) terminal is according to the indication of Access Network, and access of radio network is replied Access Network with " the Radio Resource control connection is set up and finished " signaling at last.
In this process, R99 (99 version) stage, on Random Access Channel, need to solve the random collision problem, on Random Access Channel, can not transmit larger data, and the terminal in this R99 stage need not provide this detailed terminal wireless access capability information to network when initial the access.So, when terminal inserts in initial application, do not carry any this terminal wireless access capability information in " the Radio Resource control connection is set up request " signaling, but terminal is by " the Radio Resource control connection is set up and finished " signaling after access is finished, and all this terminal wireless access capability information is notified Access Network.
The R99 later release stage, owing to introduce the high-speed packet access characteristic, the terminal in R99 later release stage must provide necessary terminal wireless access capability information when initial the access, ability information as high-speed packet access characteristic aspect, whether Access Network obtains these information and can allow terminal to insert in the reasonable decision-making of random access procedure, and terminal inserts in which way.These information must be chosen separately, and will consider to transmit on the Random Access Channel restriction of length.So, when terminal inserts in initial application, must carry the terminal wireless access capability information of part random access procedure necessity in " the Radio Resource control connection is set up request " signaling, for Access Network decision-making and configuration access way; Simultaneously, terminal also after access is finished, by " the Radio Resource control connection is set up and finished " signaling, offers Access Network with this whole terminal wireless access capability informations.
As can be seen, the complicated poor efficiency of the mode that the terminal wireless access capability information transmits repeats to transmit same ability parameter or classification.Particularly when initial application inserts, the terminal wireless access capability information parameter of necessity or classification need be picked out and put into " the Radio Resource control connection is set up request " signaling, the mistakes and omissions situation often takes place, cause protocol description usually to be changed, can not stablize.
Through evolution, random access procedure adopts as shown in Figure 2 that process realizes, concrete steps are as follows:
1) terminal sends access lead to Access Network on Physical Random Access Channel;
2) Access Network is to be used for the up ascending resource information response terminal that is used to transmit up data or controls signaling on the shared data channel of time adjustment information regularly and appointment of launching;
Be used to transmit the ascending resource information of up data or control signaling on the shared data channel that is used for the time adjustment information of up emission timing and assigns, both may be incorporated in the response of coming together;
3) terminal is according to the indication of Access Network, and the time of carrying out is adjusted, and uses the shared data channel uplink resource of assigning to carry out up data or the transmission of control signaling.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly transmits the method for terminal wireless access capability information with the control signaling in inserting at random, can be succinctly, efficiently, transfer mode is finished the transmission of terminal wireless access capability information clearly.
For solving the problems of the technologies described above, the present invention proposes to transmit with the control signaling in a kind of access at random the method for terminal wireless access capability information, and concrete steps are as follows:
