Embodiment Construction

[0066] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the appended claims of the present invention.

[0067] The implementation of the technical solution of the present invention will be described in detail below by taking VOIP as an example.

[0068] The main idea of ​​the present invention is: by checking at the PDSN whether the destination address of the message sent by the terminal user belongs to the IP address range allocated by the PDSN to the terminal, at the same time checking the content of the message, and the user's authorization policy is determined to be in line with the policy and then directly forwarded to this For end users under the PDSN, this type of traffic does not need to go through the Internet to achieve route op...

Abstract

The invention discloses a method for optimizing a grouped data service node router, a device and a system thereof; the method comprises the following: step one: a user is accessed to an AAA server for authentification; the AAA server authorizes the capacity of directly transmitting the specific application service flow to the user; step two: after the user is accessed successfully, a position message of the user is registered in a VOIP server; step three: when a certain user launches a call message to the VOIP server for calling another user, the VOIP server launches the call to another user according to a position registration message of another user; step four: after a call link is established between two users and when a grouped data service node receives the messages of a certain user, the messages which meet the condition of directly transmitting the grouped data service node are directly transmitted to another user through no Internet.

Description

technical field [0001] The present invention relates to communication technology, in particular to a route optimization method for users connected under the same packet data service node (Packet Data Service Node, PDSN) in a Code Division Multiple Access (CDMA) network. Background technique [0002] With the advancement of science and technology, communication technology has become an important factor to promote social development, and the development of mobile communication technology and IP technology has attracted special attention. The development direction of 3G mobile communication is to combine these two technologies perfectly, so that people can realize their dream of communicating with anyone at any time, any place, and with any media. In the CDMA2000 system, which is one of the 3G systems, this development direction is also fully reflected. [0003] CDMA is a commonly used multiple access modulation technology based on wideband spread spectrum technology. CDMA200...
