Method and apparatus for implementing carrying number as well as method for calling number-carried user

Abstract

The invention discloses a called method with users carried in numbers, including: step S202, a calling subscriber sends a call request message to initiate a call; step S204, sending the call request to a carrying-out-network exchanger (namely, number segment location network); step S206, the carrying-out-network exchanger transmits route inquiring message to a carrying-out-network home location register; step S208, in response to the route inquiring message, the carrying-out-network home location register returns network-pass numbers and called numbers to the carrying-out-network exchanger; step S210, the carrying-out-network exchanger connects calls to a carrying-into-network exchanger according to the network-pass numbers. The invention can easily realize number carrying between networks with different standards under conditions of small upgrading modifications to the present equipments and no new equipment increase, which enables users to select network service freely without need of number changes.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for implementing number portability, a method for calling a number portability user, and a device for implementing number portability. Background technique [0002] Number portability means that the user changes the service network but still retains the phone number assigned by the original network. For example, a user of operator A transfers to operator B, but still retains the phone number assigned by operator A, which is number portability between operators; another example, operator A has fixed network, mobile network and other Standard network, fixed phone users switch to mobile phone users, but retain the original fixed phone number, which is number portability between different networks within the same operator. [0003] In the current communication, the number portability technology mainly solves the number portability between networks of the same ...

Problems solved by technology

[0003] In the current communication, the number portability technology mainly solves the number portability between networks of the same standard. However, the number portability technology between networks of different standards is not perfect, and there has been no proposal to effectively realize the number portability between networks of different standards. The technical scheme of number portability between
