[0063] Functional Overview

[0064] As mentioned above, the present invention addresses the problems of high system cost and complicated user information update process due to the need to deploy other modules or network entities to store and maintain user terminals that have migrated from a service network in the prior art. A solution for implementing number portability of a user terminal. In this solution, when the home subscriber server of the service network where the user terminal moves out deletes the subscription information of the user terminal, it retains the status information of the user terminal, and records the status information through the status information. The user terminal has moved out of the service network.

[0065] Corresponding to the above number portability implementation solution, the present invention also proposes a call implementation solution. In this solution, the called terminal is an IMS user terminal that realizes number portability through th...

Abstract

The invention discloses a number portability implementation method and a device and a calling implementation method and a device of a user terminal. In the number portability implementation method of the user terminal, when the user terminal is transferred to a second service network from a first service network, the subscribing information of the user terminal is recorded by a second home subscriber server (HSS), and the mapping relation between the number of the user terminal and the number portability data is recorded in a number portability database; and a first HSS deletes the subscribing information of the user terminal recorded locally and records the state information of the user terminal, wherein the state information is used for indicating that the user terminal is already transferred from the first service network. The technical scheme of the invention can reduce the system cost and the complexity in the user information updating process and can improve the routing efficiency in the calling process.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for implementing number portability of a user terminal, a home subscriber server, a calling implementation method, and a home subscriber server. Background technique [0002] Number Portability (Number Portability, referred to as NP) refers to the change of the subscription network (including between different operators or between different operators) for some reason (for example, the user changes the operator, the user's permanent location changes, or the user service update). After migration between different communication networks within the same operator), the original user number can still be retained for communication. Through number portability, the interests of small operators can be protected and fair competition between operators can be promoted; at the same time, number portability can also meet the needs of customers who change their perman...
