A device determines whether an application, utilized by a user device and associated with a network, is a low latency application or a best effort application. The device designates a first network device or a second network device as a designated network device to be an IP anchor point for the application based on a set of rules. The first network device is designated as the designated network device when the application is the low latency application, or the second network device is designated as the designated network device when the application is the best effort application. The device provides, to the user device, information informing the user device that the designated network device is to be the IP anchor point for the application, and provides, to the network, information instructing the network to utilize the designated network device as the IP anchor point for the application.

A control plane (CP) entity is to adaptively reroute user plane traffic of a mobile node (MN) with use of a segment routing (SR) for IPv6. A message indicating an attachment of the MN to the mobile network is received selecting a first user plane (UP) anchor node. A first set of home network prefixes (HNPs) are allocated to the MN. An IP traffic flow using a first HNP prefix is established between the MN and a correspondent node (CN) along a first network pathdefined at least in part by the first UP anchor node and an anchor node of the CN. In response to a handover of the MN, a message indicating a subsequent attachment of the MN is received selecting a second UP anchor node. The second UP anchor node is instructed to host the first HNP prefix previously allocated by the first UP anchor node.

A method and apparatus for routing packets from a home agent to a user equipment through a first access network and a second access network. The method includes sending a first binding update message from the user equipment over the first access network to create a first binding cache entry at the home agent. The user equipment uses a home address assigned to the user equipment as a source IP address of the first binding update message. The method further includes sending a second binding update message from the user equipment over the second access network to create a second binding cache entry at the home agent. The user equipment receives packets from the home agent through the first access network and the second access network based on the first binding cache entry and the second binding cache entry.

A disclosure of the present specification provides a method for processing a NAS request message by an MMF node. The method may comprise the steps of: when it is identified that an NAS request message has been received through a second access network, checking whether a first MM context and a first security context are included therein; and acquiring a second security context from an authentication CP node, and generating a second MM context.

A moving cellular communication system comprising at least one upgraded moving relay including at least two base station functionalities and at least one mobile station functionality and a relay resource manager, all co-located, wherein each base station functionality from among the at least two base station functionalities of the upgraded moving relay is operative to communicate via antennae with at least one mobile station thereby to define a first radio link therebetween, and wherein each base station functionality has a connection to its co-located relay resource manager, wherein each mobile station functionality of the upgraded moving relay communicates via antennae with a unit which has base station functionality thereby to define at least one second radio link, respectively, wherein the relay resource manager in each individual moving relay comprises a radio resource manager; and functionality for exchanging information with relay resource managers is included in moving relays other than the individual moving relay.

Disclosed in the present disclosure is a method for realizing wireless network convergence. The method comprises: constructing a convergence link table in an AP of a wireless network cell; arranging a user management system in an external network; when cross-cell movement of a user station occurs, the user management system configuring convergence link tables in corresponding access points (APs) of two cells; and based on the configured convergence link tables, data transmitted by the user station in an original cell being transmitted in a new cell, thereby realizing wireless network convergence.

Embodiments of the present invention relate to the field of communications technologies and disclose a data processing method, apparatus, terminal, mobility management entity, and system, so as to reduce data transmission resources and avoid bringing an economic loss to a user. The method in the present invention includes: detecting a status of a data switch of a terminal, where the status includes a disabled state or an enabled state; and sending, by the terminal, a public data network PDN disconnection request to a mobility management entity MME after the status of the data switch is changed from the enabled state to the disabled state, where the PDN disconnection request carries information about a data bearer corresponding to a data domain access point name APN, and the PDN disconnection request is used to trigger the MME to delete the data bearer corresponding to the APN.

A method and a device for managing mobility of a mobile station in an Internet Protocol (IP) based network are provided. The method includes receiving a request for allocation of an IP address from an application, determining a type of IP address to be allocated to the application based on the request for the allocation of the IP address, and allocating the determined type of IP address to the application.

Provided are a method by which an access and mobility function (AMF) in a wireless communication system selectively alters a tracking area set, and a device supporting the method. The method may comprise the steps of: receiving a plurality of tracking area sets from a base station; receiving, from the base station, information about the mobility of a terminal; and selecting any one tracking area set that corresponds to the received terminal mobility information.

An IP address assignment method and an apparatus are provided, to resolve a problem in the prior art that a control plane network element cannot determine, in an IP address assignment process, a terminal device to which IP address information is to be assigned. In the method, after determining an identifier of a terminal device, a core network control plane network element in a mobile communications network assigns IP address information to the terminal device corresponding to the identifier of the terminal device. In this way, after assigning the IP address information, the core network control plane network element can determine a correspondence between the IP address information and the identifier of the terminal device.
