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.

Method for re-selecting a communication network

The invention relates to a method for data transmission with a local network, the local network comprising a plurality of local network entities for connecting mobile entities to the local network and at least one local network entity for connecting the local network to a data network. The method comprises receiving, by a first local network entity of the local network entities of the local network, a data packet, the network address of the first mobile entity on the basis of the data packet, determining, by the first local network entity on the basis of the network address of the first mobile entity, the second local network entity, via which the first mobile entity is connected to the local network, and forwarding, by the first local network entity, the data comprised by the data packet to the first mobile entity via the second local network entity.

Method for data transmission and local network entity

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

The present invention discloses a method for implementing simulation services, including the following: an interworking control unit obtains the CS domain network user identifier after detecting that the call signaling message from the CS domain network carries no CS domain network user identifier, puts the obtained user identifier into the SIP message, which is subsequently sent to the IMS network; the IMS network processes the PSTN/ISDN simulation services according to the user identifier. The present invention also discloses a system for implementing simulation service. The present invention makes it unnecessary to extend the existing SIP protocol and to perform signaling interaction between the IMS network and the interworking control unit for obtaining the user identifier, thus simplifying the implementation of the PSTN/ISDN simulation services.

Interworking method and interworking control unit, method and system for implementing simulation services

A method, an apparatus, and a system for implementing User Equipment (UE) handover are disclosed. A Mobility Management Entity (MME) obtains address information of a serving Interworking Function (IWF) by interacting with a function entity in a network and notifies the IWF to process handover according to the obtained IWF address information, so that the MME is capable of obtaining the address information of the serving IWF. Therefore, the normal proceeding of a UE handover procedure in a Circuit Switched over Packet Switched (CSoEPS) scenario is ensured.

Method, apparatus, and system for implementing user equipment handover

The present disclosure discloses a location monitoring method and apparatus. The method includes: creating a tracking area (TA) list for user equipment (UE) according to a monitoring precision indication and sending the TA list to the UE; and obtaining location information of the UE when the UE executes a location update according to the TA List and reporting the location information to a monitoring center. With the present disclosure, the monitoring location precision of a monitoring target may be set so that more accurate location information of the monitoring target can be obtained and that the needs of various monitoring tasks can be satisfied.

Location intercept method and apparatus

A method for allocating paging areas includes: determining a basic paging area currently visited by a User Equipment (UE); and allocating a paging area to this UE according to a history record of motion trace of UEs located in the basic paging area currently visited by this UE. An apparatus for allocating paging areas is disclosed.

Method and apparatus for allocating paging areas

Embodiments of the present invention provide a method, a system, and an access gateway for traffic flows to share resources. The method for traffic flows to share resources includes obtaining information of at least two traffic flows and resources requested by the at least two traffic flows, where the at least two traffic flows correspond to different Internet Protocols connections. The at least two traffic flows share the resources. The information of the at least two traffic flows is bound on an established data channel. Resources for the data channel are allocated according to the resources requested by the at least two traffic flows. The at least two traffic flows are beared on the data channel.

Method, system, and access gateway for traffic flows to share resources

A call connection method in an IP multimedia subsystem (IMS) is provided. The method includes the following steps. An entrance network element (NE) of a called network receives a session request carrying called user identification (ID) information from a calling network. When determining that the called user ID information is incomplete, the entrance NE of the called network sends a response message indicating that the called user ID information is incomplete to the calling network. The calling network updates the called user ID information according to the response message, and sends the updated called user ID information to the entrance NE of the called network. An interface NE, a called network system, a call connection system, and a method of informing a call connection failure are also provided.

Call connection method, equipment, and system in IP multimedia subsystem

A decision-making method, a decision-making system, and a PDF are disclosed herein. The decision-making method comprises: receiving application session data that carries access network data and access user data; and making policy and charging decisions according to the application session data. Through the decision-making method, decision-making system, and PDF, the application session data comprises access network data and access user data of the UE so that the PCRF can uniquely determine a user according to the access network data or the access user data and the IP address allocated by the network to the UE, and make policy and charging decisions.
