  • Patent number: 11102170
    Abstract: The application relates to a route delivery method and device. A location information of user equipment UE is received by a control plane network element device. A client IP address used by the control plane network element device to access a third-party server is determined based on the location information by the control plane network element device. An access request message is sent by the control plane network element device to the third-party server carrying the client IP address. A UE IP address assigned by the third-party server to the UE based on the client IP address is received by the control plane network element device. A user plane network element device configured to deliver a route to the UE is determined based on the UE IP address and the location information by the control plane network element device.

  • Patent number: 10348678
    Abstract: The present invention provides a network device and a method for allocating an access point name. The network device includes: a receiving module, configured to receive a user activation request sent by user equipment UE, where the user activation request includes user location information ULI; a parsing module, configured to parse the ULI received by the receiving module, to acquire an area code of a location of the UE; a determining module, configured to determine an area code set to which the area code acquired by the parsing module belongs; and an acquiring module, configured to acquire, according to a mapping relationship between the area code and an actual access point name APN, the actual APN for the UE. The embodiments of the present invention can implement centralized management on UE based on a geographical area range.

  • Patent number: 10165618
    Abstract: The present disclosure discloses a service processing method and device. In this way, when determining that an exception occurs in the packet data network gateway (PGW), the serving gateway (SGW) no longer needs to send the fact that an exception occurs in the PGW to the mobility management entity (MME), thereby reducing a signaling transmission amount in a system, and simplifying a service processing procedure. Moreover, because different deletion policies are used, service processing is accelerated, service processing efficiency of the system is further improved, and user experience is improved.

  • Patent number: 9854554
    Abstract: The present invention provides an IP address assignment apparatus and method. A packet data gateway receives a connection establishment request that is sent by a mobility management network element and that carries user location information, assigns an IP address to the terminal according to a correspondence between the user location information and an IP address pool, and feeds back the IP address to the mobility management network element. In the present invention, effects that the packet data gateway can assign an IP address according to a location of a terminal, and different IP addresses are assigned at different regions are achieved.
