Embodiment Construction

[0026] In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the present invention will be described in detail below in conjunction with specific embodiments.

[0027] Please refer to figure 1 , Shows a flowchart of the method of the present invention, including:

[0028] Step 101: When the mobile station needs home network information, the mobile station sends a home network information request message to the access gateway according to whether the learned access gateway supports allocating the home network information of the visited network for the mobile station;

[0029] Step 102: The mobile station receives a response returned by the access gateway, where the response includes home network information allocated by the access gateway to the mobile station.

[0030] Since the access gateway can notify the mobile station whether it supports the allocation of home network information of the visited network for the mobile...

Abstract

The invention provides a method, apparatus and system for acquiring network information. The method comprises: when a mobile station needs local network information, the mobile station sending request message of local network information to an access gateway according to whether acquired access gateway supports the local network information visited by the mobile station; the mobile station receiving response returned by the access gateway, the response comprising local network information distributed to the mobile station by the access gateway. By using the invention, unnecessary information interaction between the mobile station and the access gateway is reduce, when the mobile station moves, large transmission time delay is avoided.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for obtaining network information. Background technique [0002] In order to enable the mobile station (MS) to better support real-time services when roaming, the International Organization for Standardization (3GGP2, 3nd Generation Partnership Project 2) originally allocated the Home Network Information of the home network to the mobile station. On the basis of, the hometown network information of the visited (Visited Network) network allocated to the mobile station is added. [0003] In this way, the mobile station carries an indication through the Dynamic Host Configuration Protocol for IPv6 (DHCPv6, Dynamic Host Configuration Protocol for IPv6), and the indication is used to notify the access node that the Packet Data Serving Node (PDSN) wishes to assign a home for the mobile station. The hometown network information of the network still a...
