Embodiment Construction

[0042] In order to make the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] The method of route of terminal equipment of the LTE network provided in the embodiment of the present invention, mainly including:

[0044] LTE core network opens OSPF (Open Shortest Path First, Open Shortest Path Priority) Routing Protocol, and configures to import direct routes into OSPF;

[0045] The router connected to the LTE core opens the OSPF routing protocol;

[0046] When the UE enters the network to the LTE core network, the LTE core generates the IP address of the UE and creates a loopback interface of the IP address;

[0047] The router learns the routing information of the IP address of the UE through the OSPF routing protocol.

[0048] Further, the method also includes:

[0049] When the UE comes from the LTE core network:

[0050] The LTE core network ...

Abstract

The invention discloses a method and system for routing terminal equipment in an LTE network, comprising: enabling the OSPF routing protocol on the LTE core network, and configuring the direct route to be imported into the OSPF; a router connected to the LTE core network enabling the OSPF routing protocol; when a terminal equipment UE accesses the network to the LTE core network, the LTE core network generates the IP address of the UE and creates a loopback interface for the IP address; the router learns the IP address through the OSPF routing protocol Routing information for the UE's IP address. The invention realizes that the router dynamically learns the routing information of the IP address of the UE, and ensures the routing configuration of the UE by the router.

Description

Technical field [0001] The present invention relates to the field of data communication, and more particularly to a method and system of a terminal device route for an LTE network. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) network, the UE (User Equipment, User Equipment, or Terminal Device) will receive the IP (Internet Protocol, Internet Protocol) address allocated by the core network. The UE uses the assigned IP address to communicate IP communication with the application server App Server. Such as figure 1 As shown, it is assumed that the current UE entry to the LTE core network ECNS A, the assigned IP address is IP1, the UE can get the IP address of the application server App Server through the DNS (Domain Name System, Domain Name System) service to IP2, data communication The process is described as follows: [0003] Data upstream: [0004] The UE sends source address is IP1, the destination address is the packet of IP2; the base sta...
