Problems solved by technology

[0004] In the above technical solution for realizing international roaming, the user needs to initiate a USSD operation. Since the USSD operation is unique to the G network, it is not suitable for the C network.
In addition, the above-mentioned solutions require a major transformation of the equipment on the existing network. The solution based on the USSD center has new requirements for the HLR (Home Location Register, Home Location Register) and the USSD center. equipment

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The embodiment of the present invention provides a calling implementation method, such as figure 1 As shown, the embodiment of the present invention intercepts the call-back request message through the signaling interception gateway, redirects the call-back request to the call-back platform, and completes the connection and series connection of two calls by the call-back platform, realizing the initiation of a call-back in the CDMA network....

Abstract

The embodiment of the invention discloses a call realization method, a system and a device; the call realization method comprises the steps as follows: a call-back request sent by a calling user is intercepted; the call-back request is analysed; after the call-back request is an international roaming call-back request, the call-back request is re-positioned to a call-back platform; wherein, the call-back platform is used for gaining the calling number and called number carried by the call-back request after the call-back request is received; according to the calling number and the called number, the calls to the calling user and the called user are respectively sent; furthermore, the call of the calling user and the call of the called user are connected with each other. The embodiment of the invention realizes the call-back request sent in a CDMA network, converts the international call called b the user in the roaming place into an international long-distance call called in the home country by the uniform call-back platform, provides the international long-distance service of low charging for the clients, uniformly deploys the call-back platform, and affects the existing equipment less.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method, system and device for implementing a call. Background technique [0002] International roaming service is a relatively complex service, involving issues such as operation and protocol compatibility. A kind of GSM (Global System for Mobile Communications, Global System for Mobile Communications) UCB (USSD Call Back, USSD Call Back) international roaming technical solution provided by the prior art is based on the USSD (Unstructured Supplementary Services Data, unstructured supplementary data service) center The plan is realized. [0003] When a prepaid subscriber roams abroad, he must first initiate a USSD request to the USSD center, which should include the called number. Then, the USSD center initiates a call to the user. After the user answers, the USSD initiates a call to the called party. After the called party answers, the USS...
