Abstract: The present disclosure relates to a method for re-selecting a communication network. The method comprises receiving a network access request indicating a request to access to a communication network by a communication device, determining upon the basis of the network access request as to whether communication resources of the communication network are available for the communication device, and re-selecting another communication network for the communication device if the communication resources are not available for the communication device.

Abstract: A service handover control apparatus and a method using the apparatus are provided. The service handover control apparatus includes a service handover management unit collecting information associated with a transmitting terminal and a wireless access network, which operate based on an Internet Protocol multimedia subsystem (IMS), and outputting a control signal which controls service handovers of the transmitting terminal and the receiving terminal based on the collected information; and a service handover controller providing the service handover management unit with the information associated with the transmitting terminal and the receiving terminal, and controlling the service handovers of the transmitting terminal and the receiving terminal based on the control signal.

Abstract: A system and method is provided for managing an access network re-selection. The system includes computing hardware configured to provide a first indication indicating a target access network to be re-selected in case of a handover event and a second indication for establishing a certain context on a target access network. Further, computing hardware may be configured to establish the certain context on the target access network dependent on the provided second indication, said established context including a first part of the access network re-selection. And computing hardware may be configured to execute a second part of the access network re-selection due to the provided first indication and a received trigger for the handover event.

Abstract: The present disclosure relates to a system for managing an access network re-selection. The system comprises providing means, establishing means and executing means. Said providing means may be configured to provide a first indication indicating a target access network to be re-selected in case of a handover event and a second indication for establishing a certain context on the target access network. Further, said establishing means may be configured to establish the certain context on the target access network dependent on the provided second indication, said established context including a first part of the access network re-selection. Said executing means may be configured to execute a second part of the access network re-selection due to the provided first indication and the received handover trigger triggering said handover event.
