Problems solved by technology

[0007]However, the implementation of static dual-homing makes the standby softswitch idle for a long time, which not only causes waste of resources, but also increases the cost of network construction and maintenance management ; while the implementation of dynamic dual-homing requires master and backup softswitch data and heartbeat synchronization, which is more complicated to implement and data maintenance is also relatively complicated
In addition, the current disaster recovery solution is only a dual-homing method, and cannot achieve more than two multi-homing

Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] The present invention realizes the core idea of ​​NGN multi-homing as follows: firstly, a smart location belonging register SHLR is set in the NGN system for storing gateway data and user data; each gateway is configured with multiple softswitch addresses, which can initiate Registration; when a soft switch fails, the gateway initiates registration to another soft switch, and the soft switch queries the data of the gateway to the SHLR; Reply the registration success message; after the gateway is successfully registered, the softswitch updates the registration status of the gateway to the SHLR, and the SHLR saves the registration status of the gateway and the registered softswitch ID.

[0020] Fig. 1 is the gateway in the NGN system of the present invention...

Abstract

The solution comprises: setting a smart home location register (SHLR) in next generation network (NGN), which is for use in storing gateway data and subscriber data; multi soft-switch addresses can be set up on the gateway; when network runs, if one soft-switch failures, the gateway initiates a registration to another soft-switch that enquires the gateway information on SHLR; the SHLR authenticates the gateway; if the authentication passes, the SHLR returns the gateway data to the soft-switch, and the soft-switch returns the message of successful registration to the soft-switch; after the gateway makes successful registration, the soft-switch updates the registration state of the gateway on the SHLR; the SHLR saves the registration state of the gate way and its registered soft-switch ID.

Description

technical field [0001] The invention relates to the field of next generation network NGN, in particular to a device and method for realizing multi-homing in NGN. Background technique [0002] The next-generation network NGN is an open distributed network. Each media gateway can access softswitch equipment at any place through the IP packet network. However, due to the complexity of the network, the impact of various natural disasters and the reliability of the softswitch equipment itself , when a certain part of the network is interrupted, or an earthquake occurs in the location of the computer room, or the softswitch itself fails, the media gateway will not be able to provide services to users due to the loss of control of the softswitch, which will directly affect the service quality of the operator. , causing user complaints. [0003] In order to solve this problem, the concept of dual-homing is introduced in the prior art, that is, one media gateway device can belong to...
