inter-rat cell transfer method, radio access network ran server, first access network device, and second access network device

摘要

The present invention relates to the field of communications technologies and discloses a method for transfer between inter-rat cells and a device. In the present invention, a radio access network ran server receives a measurement report sent by a terminal, determines a terminal inter-rat cell based on the measurement report, and configures a resource for the terminal in the inter-rat cell. target. The configured resource is a resource to be used by the terminal to access the target inter-rat cell. the ran server sends a delivery command to the terminal. The handover command is used to instruct the terminal to deliver the target inter-rat cell, and the handover command carries a target inter-rat cell identifier and configured resource information. the ran server is configured to manage the terminal's target cell and inter-rat cell. Thus, when the transfer is performed between the inter-rat cells, the transfer can be implemented without through the main networks, thereby reducing signal exchange between a source main network and a target main network.
