Abstract

The embodiments in the present invention provide a radio node accessing a network method, a system and a relay node. In the radio node accessing a network method, the system and the relay node of the embodiments in the present invention, the authentication between the relay node and a donor evolved NodeB, a home subscriber server, or a mobility management entity is performed by carrying a certificate in messages exchanged between the relay node and the donor evolved NodeB, the home subscriber server, or the mobility management entity; a shared key similar to the one used when a user equipment accesses a network is calculated according to a Diffie Hell-man (DH) parameter exchanged between the relay node and the donor evolved NodeB, the home subscriber server, or the mobility management entity; and finally a radio bearer is established between the relay node and the donor evolved NodeB. Accordingly, the authentication method based on a certificate when a relay node accesses a network is implemented, and it is safer for a relay node at a network side to access a network.

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 follow-up evolution of the long-term evolution (Long Term Evolution-Advanced, referred to as LTE-A) introduces the relay node (Relay Node, referred to as RN). The RN is to improve the throughput of the edge of the communication cell and facilitate the temporary network of operators or users. Deployment requirements and support for group mobility. RN can be deployed in hot spots or blind spots in rural areas, 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]...
