Problems solved by technology

However, there is no mature solution for the use of dual-homing in the NGN field. If the PSTN solution is directly introduced, the dual-homing solution in the PSTN is based on the idea of ​​equipment redundancy, while the trunk media gateway (TMG) and software in NGN The switching is separated, and if planning multiple tandem offices, there are the following disadvantages:
[0006] 1) In the case of large capacity, setting up multiple redundant TMGs and soft switches will cause a large waste of equipment resources and increase network costs
[0007] 2) Realize dual-homing in NGN with the dual-homing scheme under PSTN. When only one softswitch fails, the normal TMG subordinate to the softswitch will be unusable, so that the advantages of NGN cannot be fully utilized

Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Because NGN supports the realization of dual homing, the present invention realizes the core idea of ​​dual homing as follows: at first, two softswitches that manage different areas are set as dual-homing softswitches in NGN, and two softswitches are set in these two softswitches. Relevant data of all access devices within the management range of the soft switch, and at the same time make the two soft switches establish a master-slave connection relationship with all access devices at the lower layer within the management range of the two soft switches. Since the management ranges of the two softswitches are different, for each access device, the softswitch it currently belongs to is the primary home softswitch, and the other softswitch is the secondary home softswitch. Then, in the normal operation and communication process of...

Abstract

The invention discloses a method for realizing double-ascription in the next generation network. The method includes following steps: a) sets the two soft exchanges which manage network device with different range as the double-ascription in the next generation network, the relative data of all the access device charged by the two soft exchanges are set in the double-ascription soft exchanges at the same time, and creates the master-slave relation between the double-ascription soft exchanges and all the access device; b) in the process of network running, judges that if the two soft exchangesneed to be switched, if need, then the soft exchange which is running normally currently turns over all the access devices in managing range of the double-ascription soft exchanges, otherwise, returns to step b. By using the invention, it can realize double-ascription, at the same time; it upgrades the calamity emergency processing ability.

Description

technical field [0001] The invention relates to the management technology of the next generation network (NGN), in particular to a method for realizing double homing in the NGN network. Background technique [0002] As users have higher and higher requirements for network security, reliability and network processing capabilities, operators must introduce sufficient capacity and various diversity means into the network at the beginning of network design in order to provide users with high enough services Ability to minimize the impact of failures, improve network priority recovery capabilities, dual access capabilities, and multiple routing capabilities, etc., to ensure the normal provision of services and make users highly satisfied with the services provided Spend. But on the other hand, if the core control or processing equipment adopts the main and backup mode, it will not only increase the cost of network construction and maintenance and management, but also cause great...
