A method of performing cell reselection includes receiving priority for a different frequency or RAT (Radio Access Technology) and information on a validity timer for the priority, starting the validity timer, performing cell reselection based on the priority while the validity timer is running, receiving reconfiguration information of the validity timer, and reconfiguring the validity timer based on the reconfiguration information

Methods and systems for facilitating transfer of an active session from a first device to a second device associated with the same user. A network server is configured to enable the switching or swapping of an active session from one device to another device, where both devices are associated with a common user address. The switching or swapping is implemented with no or minimal effect on the active session or awareness of the remote party. The device switch may be performed in relation to any active session, including VoIP, video conferencing, or other media sessions.

There is described a method for optimising the distribution of data objects between caches in a cache domain of a resource limited network. User requests for data objects are received at caches in the cache domain. A notification is sent from each cache at which a request is received to a cache manager. The notification reports the user request and identifies the requested data object. At the cache manager, object information including the request frequency of each requested data object and the locations of the caches at which the requests were received is collated and stored. At the cache manager, objects for distribution within the cache domain are identified on the basis of the object information. Instructions are sent from the cache manager to the caches to distribute data objects stored in those caches between themselves. The objects are classified into classes according to popularity, the classes including a high popularity class comprising objects which should be distributed to all caches in the cache domain, a medium popularity class comprising objects which should be distributed to a subset of the caches in the cache domain, and a low popularity class comprising objects which should not be distributed.

Method and apparatus efficiently signal and use resources for wireless communications supporting circuit switched (CS) and packet switched sessions (PS). Signaling and interaction between the wireless transmit/receive unit (WTRU), and various network entities, such as the Mobility Management Entity (MME), the Visitor Location Register (VLR), and Base Stations (BS), are used to implement circuit switched fall back (CSFB) in a PS system.

A method and a system for maintaining session continuity, in which the system includes: a Handover Source Function (HOSF), a Handover Destination Function (HODF), a Handover Anchor Function-Control Plane (HOAF-CP) and a Handover Anchor Function-User Plane (HOAF-UP). The method includes: a first user establishing a connection through the HOSF with the HOAF-CP and the HOAF-UP which correspond to a second user, so as to establishing a session with the second user; during session handover, the HODF that corresponds to the HOSF establishing another connection with the HOAF-CP and HOAF-UP though which the first user continues the session with the second user, so as to maintain the session continuity. When the access address or the access means of the terminal changes, or even the terminal changes during a session, embodiments of the present invention can logically replace the connection before the handover with a new connection to ensure the session continuity.

Method and system for maintaining session continuity

The present invention discloses a method and system of holding session continuity, the system includes: network, hand off source point faction(HOSF) entity, hand off destination point faction (HODF) entity, hand off anchor point faction control panel (HOAF-CP) entity and hand off anchor point faction user panel (HOAF-UP) entity. The method comprises: the first user connect with the HOAF-CP entity and the HOAF-UP entity that correspond to the second user by HOSF entity, and the first user holds a session with the second user. When performing session switching, the HODF entity that corresponds to the HOSF entity be connected with the HOAF-CP entity and the HOAF-UP entity. The first user continues the session by the connection. The present invention can replace the connection of before switching and after switching on application logic, so that ensure continuity of interactive session between users, when access address of terminal or access mode of terminal or terminal itself be changed.

A method and a system for maintaining session continuity, in which the system includes a Handover Source Function (HOSF), a Handover Destination Function (HODF), a Handover Anchor Function-Control Plane (HOAF-CP) and a Handover Anchor Function-User Plane (HOAF-UP). The method includes a first user establishing a connection through the HOSF with the HOAF-CP and the HOAF-UP which correspond to a second user, so as to establish a session with the second user. The method further includes that, during session handover, the HODF that corresponds to the HOSF establishing another connection with the HOAF-CP and HOAF-UP though which the first user continues the session with the second user, so as to maintain the session continuity. When access address or access technology of the terminal changes, or even the terminal changes during a session, the method and the system can logically replace the connection before the handover with a new connection to ensure the session continuity.
