Problems solved by technology

Traditionally, the main IPv6 transition technology has an assumption, that is, try not to modify the host, and try to use a network-based solution. The main reason is that the hosts of 1.6 billion Internet users in the world's 6.7 billion population are already in use. Now, how to upgrade these machines will be a relatively big challenge, and most users have certain difficulties in the ability to use computers to perform system upgrades

Embodiment Construction

[0040] In this embodiment, the management system that notifies the general routing encapsulation tunnel key value includes a packet data network gateway, a home user server, a mobility management unit, and a bearer-level network address translator.

[0041] The home user server is used to assign a general routing encapsulation tunnel key value to the packet data network gateway during the process of creating the packet data network connection, and notify the packet data network gateway; specifically, after receiving the general routing encapsulation key value sent by the mobility management unit After the tunnel key request information, the packet data network gateway is assigned a general routing encapsulation tunnel key, and notified to the mobility management unit.

[0042] The home user server is also used to reclaim the general routing encapsulation tunnel key value after receiving the notification request sent by the mobility management unit to disconnect the packet data ...

Abstract

The invention discloses a method and a system for managing a key value of a general routing encapsulation tunnel. The method for managing the key value of the general routing encapsulation tunnel comprises the following steps that: a packet data network gateway generates or acquires the key value of the general routing encapsulation tunnel between the packet data network gateway and a carrier grade network address translator from a home subscriber server; and when the home subscriber server generates the key value of the general routing encapsulation tunnel, during packet data network connection establishment, the home subscriber server distributes the key value of the general routing encapsulation tunnel for the packet data network gateway and informs the packet data network gateway of the key value of the general routing encapsulation tunnel. By the method, the property of managing the key value of the general routing encapsulation tunnel by the system can be enhanced, and the system capability can be enhanced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for managing general route encapsulation tunnel key values. Background technique [0002] Such as figure 1 As shown, the Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) consists of the Evolved Universal Terrestrial Radio Access Network , referred to as E-UTRAN), mobility management unit (Mobility Management Entity, referred to as MME), serving gateway (Serving Gateway, S-GW), packet data network gateway (Packet Data Network Gateway, referred to as P-GW or PDNGW), Home Subscriber Server (HSS for short), Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) entity and other support nodes. Data is transmitted between the packet data network gateway and a carrier grade network address translation (CGN for short) through a generic routing enca...
