Description
Technical field
The present invention relates to communication technical field, relate in particular to method and device that a kind of initial network inserts.
Background technology
LTE-Advanced (Long Term Evolution Advanced) is the further enhancing of LTE technology, to continue to keep the absolute competitive advantage of 3GPP (3rd Generation Partnership Project, third generation partner program) in following 4G standard.Present LTE-Advanced system requirements: the UE of LTE (User Equipment, subscriber equipment) can normally move in the LTE-Advanced system; Simultaneously, the UE of LTE-Advanced also requirement can in the system of LTE, move.
In addition, in order to satisfy IMT-Advanced (International Mobile TelecommunicationAdvanced, the further enhancing of international mobile communication system) requirement, 3GPP LTE-Advanced system has agreed that at present introducing the carrier wave technology of converging comes system bandwidth is expanded, to support the peak data rate up to 1Gbps.Wherein, the main thought that carrier wave converges is exactly that a plurality of composition carrier waves are pooled a carrier wave that is higher than 20M, to support higher data speed.For example, downlink bandwidth can be converged by the carrier wave of 5 20M and form.
In any one wireless communication system, the initial network access procedure of UE all is very crucial process.In the LTE-Advanced system, the initial network access procedure of UE, mainly realize by following steps:
1) UE carries out Cell searching, and finds an interim composition carrier wave;
2) UE receives BCH (Broadcast Channel, broadcast channel) from described interim composition carrier wave, and obtains system information and PRACH (Physical Random Access Channel, Physical Random Access Channel) resource information etc. from described BCH;
3) UE sends preamble (lead code) on 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 competition solution message of eNodeB feedback, and including eNodeB in this competition solution message is the new right information of up-downgoing carrier wave that UE distributes according to described ability information;
6) UE moves to newly assigned up-downgoing carrier wave to last, and reports to eNodeB.
In implementing process of the present invention, the inventor finds that there are the following problems at least in the prior art:
UE has certain randomness when carrying out Cell searching, UE chooses an interim composition carrier wave, and sends upstream message according to this interim PRACH resource of forming on the carrier wave; But, eNodeB this moment and do not know UE selected be which forms carrier wave, can receive the message that eNodeB sends safely in order to make UE, eNodeB need send same downstream message simultaneously on a plurality of composition carrier waves.Like this, owing to repeated to send same message on a plurality of composition carrier waves, make downlink radio resource cause waste.
Summary of the invention
Method and device that embodiments of the invention provide a kind of initial network to insert are in order to solve the wasting of resources problem in the initial network access procedure in the existing LTE-Advanced system.
For achieving the above object, embodiments of the invention adopt following technical scheme:
The method that a kind of initial network inserts comprises:
Send message to terminal, comprise the indication information of the access carrier of base station appointment in the described message;
