Problems solved by technology

[0007] It can be seen from the above that there are serious routing detours in the existing technology, which increases a large amount of unnecessary core network data traffic and delay, and a lot of data needs to be transmitted through tunnels when transmitting in the core network, which further increases the network burden and delay.

Embodiment 1

[0036] FIG. 2 is a flow chart of route optimization in Embodiment 1 of the present invention. Assume that mobile terminal A is a MIP or simple IP terminal, and AGW (also applicable to other IP access functional entities such as PDSN or CAP) may run the proxy mobile IP function, and the communication peer B may be a MIP terminal or a simple IP terminal. The mobile terminal A sends an IP data packet to the communication peer B through the air interface, and the data packet first arrives at the access gateway AGW. The processing flow of the AGW is shown in Figure 2, including the following steps:

[0037] a. After the AGW receives the IP data packet sent by terminal A, it queries its own access list to determine whether the IP address of the registered terminal matches the destination address in the IP packet header.

[0038] b. If there is a match, that is, the communication peer also uses the same AGW (or PDSN, or CAP, etc.) to access the mobile core network, then directly for...

Embodiment 2

[0047] Since the data service of the terminal also includes many non-end-to-end applications accessing the Internet and various application servers, for these IP data traffic, the AGW can pre-screen out the destination address in non-end-to-end applications through a preconfigured IP address range table. The mobile terminal retrieves the access list using the IP data packets within the range, and directly performs normal FA or proxy mobile IP processing operations. This improvement can reduce some unnecessary AGW retrieval operations and reduce the burden of AGW on IP packet processing, especially when the terminal has a large access traffic to various application servers and outside the network, its significance is more obvious. The specific processing flow of AGW is shown in Figure 3:

[0048] (1) According to the pre-configured IP address range table, it is judged whether the destination address is within the optimizeable range.

[0049] Wherein, the pre-configured IP addr...

Abstract

The invention discloses a routing optimization method and device in a grouping and moving network, comprising: after receiving the IP data package sent by a mobile node, the IP accessing function body searches the visiting user list which is stored, and if the IP address which is matched with a destination address in the IP data package exists, the IP data package is directly transmitted to a destination terminal. The invention eliminates the unnecessary routing detour and resource occupation when the mobile node communicates with the correspondent terminals which belong to the same access gateway, and also reduces the possibility of time delay and package missing and improves the utilization ratio of the network transmission resource and the behavior of the time delay sensitive business.

Description

technical field [0001] The invention relates to packet mobile network technology, in particular to a routing optimization method and device in a packet mobile network. Background technique [0002] With the wave of global IP becoming more and more intense, more and more communication systems adopt IP as the transmission protocol in the system in the standard. In the field of mobile communication, since the terminal needs to flexibly change the access location, an enhanced mechanism is needed to complete the mobility management based on the IP bearer. Under this trend, the Internet Engineering Task Force IETF organization first proposed the concept of mobile IP and has conducted research for more than 10 years. Now Mobile Internet Protocol Version 4 (MIPv4) and Mobile Internet Protocol Version 6 (MIPv6) have officially become The standard of IETF has been adopted by various mobile communication standard organizations. At the same time, various enhancement technologies aimin...
