Description
Technical field
The present invention relates to communication technical field, particularly relate to method and the device of the access of a kind of initial network.
Background technology
LTE-Advanced (Long Term Evolution Advanced) is the further enhancing of LTE technology, to continue to keep 3GPP (3rd Generation Partnership Project, third generation partner program) the absolute competitive advantage in following 4G standard.The UE (User Equipment, subscriber equipment) of current LTE-Advanced system requirements: LTE normally can run in LTE-Advanced system; Meanwhile, the UE of LTE-Advanced also requirement can run in the system of LTE.
In addition, in order to meet IMT-Advanced (International Mobile TelecommunicationAdvanced, the further enhancing of ternational Mobile Telecommunications system) requirement, 3GPP LTE-Advanced system has agreed to that introducing carrier convergence technology expands system bandwidth, to support the peak data rate up to 1Gbps at present.Wherein, the main thought of carrier convergence is exactly multiple component carrier is pooled a carrier wave higher than 20M, to support higher data rate.Such as, downlink bandwidth can be formed by the carrier convergence of 5 20M.
In any one wireless communication system, the initial network access procedure of UE is all very crucial process.In LTE-Advanced system, the initial network access procedure of UE, realizes mainly through following steps:
1) UE carries out Cell searching, and finds an interim component carrier;
2) UE receives BCH (Broadcast Channel from described interim component carrier, broadcast channel), and obtain system information and PRACH (Physical Random Access Channel, Physical Random Access Channel) resource information etc. from described BCH;
3) UE sends preamble (lead code) in selected PRACH resource, simultaneously receiving random access response message;
4) UE sends the uplink message of dispatching to eNodeB (base station), wherein includes the ability information of UE;
5) UE receives the contention resolved message of eNodeB feedback, and including eNodeB in this contention resolved message according to described ability information is the right information of new up-downgoing carrier wave that UE distributes;
6) UE moves to newly assigned up-downgoing carrier wave to upper, and reports to eNodeB.
In the practice of the invention, inventor finds that in prior art, at least there are the following problems:
UE has certain randomness when carrying out Cell searching, and UE chooses an interim component carrier, and sends upstream message according to the PRACH resource on this interim component carrier; But now and do not know selected by UE to be which component carrier, the message receiving eNodeB safely to enable UE and send, eNodeB needs to send same downstream message on multiple component carrier eNodeB simultaneously.Like this, owing to multiple component carrier repeating have sent same message, downlink radio resource is made to cause waste.
Summary of the invention
A kind of method that embodiments of the invention provide initial network to access and device, in order to solve the problem of resource waste in existing LTE-Advanced system in initial network access procedure.
For achieving the above object, embodiments of the invention adopt following technical scheme:
