Abstract
The utility model relates to a method which uses dispatching request to transmit terminal wireless access ability information in random access; after the terminal is connected to the network at layer 1, the terminal conducts time adjustment according to the access network indication and sends a dispatching request which carries the whole wireless access ability information of the terminal to the access network; when receiving the dispatching request, the access network saves the wireless access ability information of the terminal, distributes and returns the resource which is used for transmitting data or control signaling on sharing data channel to the terminal.
Description
Technical field
The present invention relates to the method for designing of random access procedure in a kind of wireless communication system, refer more particularly to the method for designing that the terminal wireless access capability information transmits in 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:
Layer one ability parameter or classification: described in the terminal wireless access capability for layer one protocol layer concrete ability situation.As the physical layer ability: as RF capabilities, up-downgoing physical channel ability parameter, up-downgoing transmission channel ability parameter or the like.

Other ability parameter or classification: it has described the concrete ability situation of 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, because 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 keep transmitting length restriction on the Random Access Channel.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, offer the Access Network decision-making and the configuration access way is used; Simultaneously, terminal also after access is finished by " Radio Resource control connection set up finish " signaling, this whole terminal wireless access capability informations is offered Access Network in detail.
As can be seen, the design of the terminal wireless access capability information transmission complicated poor efficiency that becomes can repeat 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 situation of mistakes and omissions 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 with time adjustment information that is used for up emission timing and the resource information response terminal that is used to send dispatch request;
3) terminal is according to the indication of Access Network, the time of carrying out is adjusted, on the time-frequency domain resources of shared data channel that Access Network is assigned or Physical Random Access Channel, send dispatch request then, for follow-up data and control signaling send the information applications adequate resources to Access Network;
4) Access Network is adjusted resource allocation according to the dispatch request of terminal, is the rational resource of terminal distribution, and by assigning the resource information answer terminal that is used to transmit data or control signaling on the shared data channel;
5) terminal uses the shared data channel resource of assigning to carry out data or the transmission of control signaling according to the indication of Access Network.
More than 5 steps be that the flow process that Long Term Evolution a kind of optimizes direction realizes, but this realization is on the principle, regulation is not made in the transmission of terminal wireless access capability information.
