Abstract

The embodiment of the invention relates to a radio node network-accessing method and system as well as a relay node. In the radio node network-accessing method and system as well as the relay node in the embodiment of the invention, through carrying a certificate in a message interacted between the relay node and a donor base station or home subscriber server or mobile management entity, authentication between the relay node and the donor base station or home subscriber server or mobile management entity is carried out; and through a DH (Diffie-Hellman) parameter between the relay node and the donor base station or home subscriber server or mobile management entity, a shared key similar to a key when user equipment accesses network is calculated, and finally, a radio bearer between the relay node and the donor base station is established, therefore, the authentication method based on the certificate when the relay node accesses the network is realized, and the relay node at the network side accesses the network more safely.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and relay node for wireless node network access. Background technique [0002] The subsequent evolution of Long Term Evolution-Advanced (LTE-A for short) introduces the relay node (Relay Node, RN for short), which is a temporary network for improving the throughput of the edge of the communication cell and convenient for operators or users. Deployment requirements and support for group mobility. RN can be deployed in hot spots or blind spots in villages, cities, indoors, etc. [0003] In an existing radio access network (Radio Access Network, RAN for short), when the RN accesses the network, the RN is similar to an additional user equipment (User Equipment, UE for short). Therefore, when the RN accesses the network, the certificate-based authentication method cannot be implemented. Contents of the invention [0004] The purpose of the embodiment of th...
