Claims17
A mobile terminal comprising:
- a transmission unit configured to transmit a request message for handover information to a network device;
- and
- a receiving unit configured to receive a response message including the handover information from the network device, wherein:
- the request message and the response message are transceived by an application layer protocol,
- the application layer protocol corresponds to a Session Initiation Protocol (SIP),
- the transmission unit transmits the request message using an SIP SUBSCRIBE request or an SIP PUBLISH request,
- the request message includes the handover information,
- if the transmission unit transmits the request message using the SIP SUBSCRIBE request, the SIP provides an SIP event service,
- if the transmission unit transmits the request message using the SIP PUBLISH request, the SIP provides an SIP presence service, and
- the handover information includes at least one of a network type, an operator name, and a roaming agreement.
A network device comprising:
- a receiving unit configured to receive a request message for handover information from at least one mobile terminal;
- and
- a transmission unit configured to transmit a response message including the handover information to the at least one mobile terminal, wherein:
- the request message and the response message are transceived by an application layer protocol,
- the application layer protocol does not provide the handover information to a data link layer,
- the application layer protocol corresponds to a Session Initiation Protocol (SIP),
- the request message corresponds to an SIP SUBSCRIBE request or an SIP PUBLISH request,
- the request message includes the handover information,
- if the request message corresponds to the SIP SUBSCRIBE request, the SIP provides an SIP event service,
- if the request message corresponds to the SIP PUBLISH request, the SIP provides an SIP presence service, and
- the handover information includes at least one of a network type, an operator name, and a roaming agreement.
