Embodiment
Be described in detail below in conjunction with the methods, devices and systems of accompanying drawing embodiment of the invention sub-district relay and control.
At present, the Relay in the LTE system does not have the identify label of oneself, relaying ID (Relay ID), and in embodiment of the present invention, the base station need communicate with Relay, and in order to accomplish such reciprocal process, system is that relay station distributes relaying ID.In communication process, relay station obtains relaying ID through access procedure, and communicates.
Of Fig. 1, be first embodiment of relay station method for communicating of the present invention, about a kind of relay station method for communicating, comprising:
S101: the relaying identify label ID that obtains relay station;
S102: communicate according to said relaying ID.
The scheme that provides through this embodiment; Relay station obtains the relaying ID of system for its distribution; Then relay station just can communicate according to the miscellaneous equipment in relaying ID that obtains and the system; The base station just can effectively be managed relay station newly-increased in the system according to relaying ID, improves the efficient of system.
In order to guarantee that this method can be compatible with prior art, in embodiment of the present invention, relay station uses existing already present sign.The identify label of having used in the sub-district now mainly contains two kinds: cell identity sign Cell ID and subscriber equipment identify label UE ID.Cell ID can not be used as Relay ID; Because the communication between base station and the relay station should be consistent with the communication process of base station and user terminal UE; This is for present standard is done as far as possible little change, like this, and for the base station; Relay station is exactly a special UE, and can not regard the Cell that another one is different as.
Therefore, in the specific embodiment of the invention, can will give relay station as relaying ID for the field that is not used in UE ID in the field of reserving in the subscriber equipment identify label with in the version of LTE Release8.Specifically can for the base station when receiving the access request that newly-increased relay station sends, from the field of reserving for UE ID, select a field to this relay station, as relaying ID, the field of this reservation can be FFF3-FFFC.
Relay station sends the access request message to the base station when access network, the access response message is returned after receiving this access request message in the base station, and this inserts in response message, is included as the relaying access ID that this relay station distributes, and is used for this relay station and inserts.Simultaneously, also comprise in this access response message and be used for this relay station carries out proper communication behind access network trunking traffic ID.The part field of this reservation is inserted ID as the relaying of relay station,, then can compete and use the relaying that distributes to insert ID if a plurality of relay stations are arranged.For example have; FFF3 is inserted ID as relaying, then the several ID that can be when the relay station proper communication of the residue among the FFF3-FFFC, i.e. trunking traffic ID; After relay station inserts successfully; By base station selected one and distribute to this relay station, if being distributed into relaying, FFF3 inserts ID, then FFF4-FFFC can be used as trunking traffic ID.In addition, as required, can a trunking traffic ID be distributed to the set of a Relay.
Newly-increased relay station is in order to solve the not high problem of communication quality between base station and the subscriber equipment, can to guarantee to be not need relay station under the situation of proper communication in base station and subscriber equipment in system.But; In the process that existing sub-district relaying is transmitted, the signal that relay station can be received oneself all is transmitted to Correspondent Node, does not consider whether the communication quality between base station and the subscriber equipment needs relaying; This can cause the workload of relay station itself very big; This proposes higher requirement to transmitting power of relay station, requires the relay station can be with bigger power work, and can produce bigger interference at neighbor cell.To this problem, the embodiment of the invention proposes a kind of method, and is of Fig. 2, and second embodiment for relay station method for communicating of the present invention comprises:
S201, relay station initiate to insert request message to the base station.
S202, base station receive the access request message from relay station.
The access response message is returned to relay station in S203, base station, comprises trunking traffic ID in the said access response message.
In practical application; The base station can be with the whole of the reserved field in the subscriber equipment identify label or a part; Transmit the field selected of identify label as relay station access identity sign and relay station, but relay station access identity sign and the relay station forwarding identify label of specifically distributing to each relay station can only respectively be one.
In the process that existing relaying is transmitted, the signal that relay station can be received oneself all is transmitted to Correspondent Node, does not consider whether the communication quality between base station and the subscriber equipment needs relaying.This mainly is because existing relay station does not have own identify label in the sub-district, so existing base station can't carry out that independent controling cause to relay station, in view of this, this step is sent the relay station ID that communicates by letter by the base station to relay station earlier.
S204, relay station receive the access response message that the base station is returned, and solve the relay station communication ID in the said access response message.
Relay station obtain trunking traffic ID process can for:
Receiving the access of returning the base station replys;
Insert ID if comprise relay station during said access is replied, further resolve the control signaling that inserts in the response message;
Further search the reply data that inserts in the response message through the control signaling of resolving, and inquiry obtains trunking traffic ID from said reply data.
S205, base station send control information to relay station, and the relaying forwarding state of relay station has been specified in said control information, and carry the trunking traffic ID of relay station.
The base station is specially to the process that relay station sends control information: the base station sends control information to the mode of one group of relay station with broadcasting.This technical scheme mainly is based on one group of relay station and shares the prerequisite that a relay station is transmitted identify label.
Said control information comprises a control strategy to relay station, and comprising needs relay station to transmit which signal, with what forwarded in form contents such as (parameters such as emitted power, frequency band).This control strategy sends to relay station with the form of control information, and said control information also carries the trunking traffic ID of the relay station of realizing this control strategy.
S206, relay station receive the control information from the base station, if the trunking traffic ID that said control information is carried is consistent with the trunking traffic ID in inserting response message, carry out the relaying forwarding according to the state of said control information appointment.
Through said trunking traffic ID, relay station picks out the base station and issues the control information of oneself, carries out relaying according to the state of said control information appointment and transmits, thereby realize the control of base station to relay station.
Technical scheme through present embodiment; For relay station distributes trunking traffic ID; The base station is controlled relay station through said trunking traffic ID, and then makes the not high signal of communication quality between a relay station repeating base station and the subscriber equipment, has alleviated the workload of relay station itself; Reduce the power of relay station, finally reduced the presence of intercell interference of bringing by relay station.
