Embodiment Construction

[0065] The technical solutions of the present invention will be described in detail below with reference to the drawings and specific embodiments to further understand the objectives, solutions and effects of the present invention, but not as a limitation to the protection scope of the appended claims of the present invention.

[0066] The implementation of the technical solution of the present invention will be described in detail below by taking VOIP as an example.

[0067] The main idea of ​​the present invention is to check 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 by the PDSN, and at the same time check the message content, and the user's authorization policy determines that it is in compliance with the policy and then directly forward it to this End users under PDSN make this type of traffic do not need to go through the Internet to achieve routing optimization, which reduces...

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 method for route optimization between users accessing under the same 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 in promoting social development, and the development of mobile communication technology and IP technology has attracted particular attention. The development direction of 3G mobile communication is the perfect combination of these two technologies, so that people can realize their dream of communicating with anyone at any time, any place, and using any medium. This development direction is also fully reflected in the CDMA2000 system, which is one of the 3G systems. [0003] CDMA is a commonly used multiple access modulation technology based on wideband spread spectrum technology. CDMA2000 is one of t...
