Description

Communication method and access network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication method and an access network device.

Background

The fifth generation mobile communication technology (5th-generation, 5G) network provides multiple slicing modes, which can satisfy the needs of both customers (2C) and enterprises (2B).

The transceiver devices (e.g. access network devices) in a 5G network are typically multi-antenna devices, such as: 64 Transceiver and Receiver (TR) devices, resulting in a very high networking cost. Therefore, operators are looking for a solution in which multiple operators co-establish a base station and use the co-established base station for network deployment. The co-building of the base station means that one base station can meet the requirements of multiple operators, and the equipment of the multiple operators is not centralized in the same base station.

How the base station after being co-constructed distinguishes the 2B and the 2C of each operator, and accesses the 2B and the 2C of each operator to the corresponding core network becomes a problem to be solved urgently.

And determining the service type of the current service initiated by the terminal according to the preset service. Each operator corresponds to at least one operator core network, so when the access network equipment determines that at least one of the service type and the target address meets the preset condition, the terminal is accessed to the operator core network corresponding to the target address; the operator core network corresponding to the target address is an operator core network in at least one operator core network.

When the base station determines the service type of the service initiated by the terminal, it is also required to determine whether the service type and the target address of the service initiated by the terminal meet preset conditions. When at least one of the service type and the target address is determined to meet the preset condition, the base station accesses the terminal to the core network of the operator corresponding to the target address, so that the problem of how to distinguish 2B and 2C of each operator and access the 2B and 2C of each operator to the corresponding core network by the base station after co-construction is solved.

When the antenna unit of the access network device 2 receives the downlink data, the downlink data needs to be distinguished through the second combiner. When it is determined that the downlink data includes downlink data of the private network or the public network of the terminal 1 of the operator a, the downlink data needs to be transmitted to the terminal 1 of the operator a through the carrier link for transmitting the downlink data in the first communication link. When it is determined that the downlink data includes downlink data of the public network or the private network of terminal 1 of operator B, the downlink data needs to be transmitted to terminal 1 of operator B through the carrier link for transmitting the downlink data in the second communication link.
