Abstract
A method of providing session mobility and a user terminal are provided. The method includes, when a session is set through one interface, receiving a request for session transfer to a network corresponding to another interface, checking the available resource capacity of the network to which the session will be transferred, and determining whether or not to transfer the session based on the result of the check operation and establishing a session with the network. The method can improve the reliability of an Internet protocol (IP) multimedia subsystem (IMS) service continuity function.
Claims20
A method of providing session mobility implemented in a user terminal having interfaces corresponding to two or more networks, the method comprising:
- when a session is set through one of the interfaces, receiving a request for session transfer to a network corresponding to another interface;
- checking available resource capacity of the network to which the session will be transferred;
- and
- determining whether or not to perform session transfer based on the result of the check operation, and establishing a session with the network.
A method of providing session mobility, comprising:
- receiving a session transfer request from a user terminal;
- checking available resource capacity of a network being accessed based on multimedia stream information included in the session transfer request;
- and
- determining whether or not to establish a session according to the result of the check operation, and establishing the session.
A user terminal, comprising:
- a communicator including different types of two or more interfaces;
- a network checker checking, when a session is established through one of the interfaces and a request for session transfer to a network corresponding to another interface is received, available resource capacity of the network corresponding to the other interface;
- and
- a session establishment unit establishing a session to the network corresponding to the other interface according to the result of the check operation of the network checker.
A user terminal, comprising:
- a network checker checking, when a session transfer request is received from another user terminal, available resource capacity of a network being accessed based on multimedia stream information included in the session transfer request;
- and
- a session establishment unit performing session establishment based on the session transfer request according to the result of the check operation of the network checker.
