The present invention provides a method for improving Network Discovery and Selection suitable for a UE which is moving into a new TA, which comprises: receiving, by a MMF, a TAU request including the new TA from the UE; allocating, by the MMF, a new TA List according to the new TA in the TAU request; sending, by the MMF, the new TA List to the UE; sending, by the MMF, a TA information to a Mobility Policy Function, MPF, for updating mobility policy of the UE if the new TA is a special TA covered by different networks.

Method and device for improving network discovery and selection

Embodiments of the present invention disclose a method and apparatus for processing a short message, and a system, and relate to the field of communications technologies, which enable a terminal to receive a short message in time on the premise of not interrupting a current PS service, enhance user experience, reduce resource consumption of a short message service, and optimizes a utilization rate of a network resource. A method for processing a short message provided in an embodiment of the present invention includes: determining, by a network element in 2G or 3G, that a current service type is short message; receiving, by the network element, a short message sent by an MME; and delivering, by the network element, the short message to a terminal through an established PS connection.

Method, apparatus and system for processing short message

A location update method, and a heterogeneous network communications system and a device are provided herein. The method includes: an information server receives a location update request message from a multimode terminal; the information server searches the pre-stored location area mapping information for the location area information of the second interface; and the information server sends the location update request message of the second interface to a second Paging Coordinator (PC) corresponding to the second interface, where the request message carries the found location area information of the second interface so that the second PC can update existing location area information of the second interface. The system includes an information server, a first PC and a second PC. Therefore, the interfaces of the multimode terminal do not need to initiate location update frequently, message interactions between the terminal and the network are reduced, and not all interfaces of the multimode terminal need to report location area information, thus saving power.

Location update method, heterogeneous network communications system and device

A method of paging for a wireless device with multiple radio interfaces corresponding to multiple access networks. The method provides a first interface from the multiple radio interfaces to listen to paging for the multiple radio interfaces; turns the rest of the multiple radio interfaces into deep-sleep mode; and maintains attachment for each of the deep-sleep interfaces to a corresponding serving base station or access point.
