Abstract

The invention discloses a radio access network switching method, a base station and a communication method of the base station. The radio access network switching method comprises the following steps:the base station in an evolved universal terrestrial radio access network E-UTRAN makes a decision of switching user equipment UE to a 5G radio access network 5G-RAN and sends a switching requirementmessage to a mobility management entity MME; the MME sends a relocation request message to a 5G core network control plane 5GC CP and receives a relocation response message from the 5GC CP; the MME sends a switching instruction message to the base station in the E-UTRAN; the base station in the E-UTRAN sends the switching instruction message to the user equipment UE, so that the UE is switched tothe 5G-RAN from the E-UTRAN, wherein in the process that the UE is switched to the 5G-RAN from the E-UTRAN, the base station in the E-UTRAN and the base station in the 5G-RAN carry out direct data forwarding or indirect data forwarding.

Description

technical field [0001] The present invention generally relates to the field of wireless communication, and more specifically relates to a wireless access network switching method base station and a communication method for the base station. Background technique [0002] Modern mobile communication tends to provide users with high-speed multimedia services, such as figure 1 Shown is the system architecture diagram of System Architecture Evolution (SAE). in: [0003] User Equipment (UE) 101 is a terminal device for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNodeBs / NodeBs) providing UEs with an interface to access a radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity....
