A terminal switching method, base station and terminal switching system

Abstract

The present invention provides a terminal switching method, a base station and a terminal switching system. The method includes: when receiving a witching request sent by an original base station which belongs to a terminal simultaneously attached to a cluster core network and an LTE core network, a target base station returns a switching request confirmation to the original base station, and the original base station sends a connection reconfiguration message to the terminal according to the switching request confirmation; after receiving a connection reconfiguration completion message sent by the terminal, the target base station acquires type of service of the terminal; when the terminal has both ordinary services and cluster services, the target base station sends the path switching request to the cluster core network and the LTE core network, respectively; after receiving a path switching confirmation returned by the cluster core network and the LTE core network, the target base station sends an UE context release message to the original base station; and the target base station receives an UE context release completion message returned by the original base station after releasing the UE context. The present invention can perform the switching process when the terminal has both ordinary services and cluster services.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal switching method, a base station and a terminal switching system. Background technique [0002] The so-called LTE (Long Term Evolution, Long Term Evolution) public network cluster refers to carrying private network cluster services through the LTE public network. Since cluster services have high security requirements, network isolation is usually required. Current isolation solutions include core network isolation, access network isolation, and both core network and access network isolation solutions. In the prior art, the network architecture of core network isolation and access network sharing is usually adopted, please refer to figure 1 , the advantage of this network architecture is that it can not only meet the security level requirements of the physical entity isolation level, but also fully rely on the access network of the LTE public network to ...

Problems solved by technology

[0003] When the terminals in the network architecture where the core network is isolated and the access network is shared have both common services and cluster services, there is currently no corresponding solution for how to deal with the handover
