Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0043] The terminal device routing method of the LTE network provided by the embodiment of the present invention mainly includes:

[0044] The LTE core network opens the OSPF (Open Shortest Path First, open shortest path first) routing protocol, and configures the direct route to be imported into OSPF;

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

[0046] When the UE accesses the LTE core network, the LTE core network generates the IP address of the UE and creates a loopback interface for 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 disconnects from the LTE ...

Abstract

The invention discloses a method and system for routing terminal equipment of an LTE network, and the method comprises the steps: an OSPF routing protocol is enabled through an LTE core network, and adirect connection route is guided into an OSPF; a router connected to the LTE core network starts an OSPF routing protocol; when terminal equipment UE accesses the LTE core network, the LTE core network generates an IP address of the UE and creates a loopback interface of the IP address; and the router learns the routing information of the IP address of the UE through an OSPF routing protocol. According to the invention, the router can dynamically learn the routing information of the IP address of the UE, and the configuration of the router for the UE routing is ensured.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a method and system for routing terminal equipment in an LTE network. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution) network, when a UE (User Equipment, user equipment or terminal device) accesses the network, it will obtain an IP (Internet Protocol, Internet Protocol) address allocated by the core network. The UE uses the allocated IP address to perform IP communication with the application server APP Server. Such as figure 1 As shown, assuming that the current UE is connected to the LTE core network eCNS A, and the assigned IP address is IP1, the UE can obtain the IP address of the application server APP Server through the DNS (Domain Name System, Domain Name System) service as IP2, and the data communication The process is described as follows: [0003] Data upstream: [0004] The UE sends a data packet whose source address is I...
