Abstract
Methods for avoiding handover failure are provided. The method includes determining, by a source Base Station (BS), to perform a handover of a User Equipment (UE); determining, by the source BS, whether a target BS connects with a user plane node serving the UE at the source BS; and releasing resources, when the target BS does not connect with the user plane node serving the UE at the source BS.

A method for avoiding handover failure by a source base station (BS) in a wireless communication system, the method comprising:
- transmitting, to a target BS, first information corresponding to the source BS, the first information including information associated with a local home network and information associated with a sub-network;
- receiving, from the target BS, second information corresponding to the target BS, the second information including information associated with a local home network and information associated with a sub-network;
- determining to perform a handover of a terminal to the target BS;
- identifying whether the local home network identified by the first information and the local home network identified by the second information are a same local home network based on the first information and the second information;
- and
- releasing a packet data network (PDN) connection related to a local home network corresponding to a terminal in response to the handover of the terminal, unless the local home network identified by the first information and the local home network identified by the second information are identified to be the same local home network.
A source base station (BS) for avoiding handover failure in a wireless communication system, the source BS comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller coupled with the transceiver and configured to:
- transmit, to a target BS, first information corresponding to the source BS, the first information including information associated with a local home network and information associated with a sub-network,
- receive, from the target BS, second information corresponding to the target BS, the second information including information associated with a local home network and information associated with a sub-network,
- determine to perform a handover of a terminal to the target BS,
- identify whether the local home network identified by the first information and the local home network identified by the second information are a same local home network based on the first information and the second information, and
- release a packet data network (PDN) connection related to a local home network corresponding to a terminal is response to the handover of the terminal, unless the local home network identified by the first information and the local home network identified by the second information are identified to be the same local home network.
