In network insertion, if the terminal accessed under relay station is many, backhaul link resource will certainly be caused nervous, at this moment system just should start the access control of terminal, in other words, when back haul link resource-constrained, terminal access network more just should be forbidden in base station, to ensure the business impression of other accessed terminal.For this reason, prior art provides a kind of admittance control method, for realizing the access control to terminal when backhaul link resource is limited.Wherein, the implementation procedure of this admittance control method as shown in Figure 1, comprises the following steps:
101, set up wireless heterogeneous networks (Radio Resource Control, RRC) between terminal (User Equipment, UE) and relay station (Relay) to connect;
102, terminal initiatively initiating business request (Service Request) or after receiving network side downlink data arrival notice initiating business request to terminal mobility management entity (UE Mobility ManagementEntity, UE_MME);
103, after terminal mobility management entity (UE_MME) receives the Service Request of terminal initiation, initiate carrying and set up request (Bear Setup Request) to relay station;
104, relay station carries out the access control of access link after receiving the Bear Setup Request of UE_MME initiation, if access link does not have resource to hold this carrying, then return refusal response directly to UE_MME, the service request of terminal can be rejected; If access link has resource to hold this carrying, then to relay station Mobility Management Entity (Relay_MME), relay station packet gateway (Relay, Relay_Packet Data Net Gateway, Relay_PGW)/SGW (Single Gateway, SGW) initiates bearing resource amendment request (Request Bear Resource Modification);
105, Relay_MME receives the bearing modification instruction that Relay_PGW/SGW initiates;
106, Relay_MME initiates carrying to base station (eNB) and sets up request (Bear Setup Request), at this moment the access control of back haul link can be carried out in base station, if back haul link does not have resource hold this carrying, so this carrying can be refused in base station, and the service request of terminal also can be rejected.
