Route addressing method, system and device adopting virtual number

Abstract

The embodiment of the invention discloses a route addressing method, system and device adopting a virtual number. The method comprises the steps of: storing a sharing a sharing MSISDN (Mobile Station Integrated Services Digital Network) number in a home location register (HLR); receiving a call request carrying the virtual number of a called subscriber by a mobile service switching center / visitor location register (MSC / VLR) where a call subscriber is in, requesting the sharing MSISDN number to the HLR; and according to a sharing MSISDN allocated by the HLR, addressing the MSC / VLR wherein the called subscriber is in. By applying the invention, route addressing can be carried out on the called subscriber adopting the virtual number, and equipment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a routing addressing method, system and device using virtual numbers. Background technique [0002] Before a mobile communication system provides mobile services such as voice services to mobile users, it needs to assign a number that can uniquely identify the mobile user to the mobile user. In the initial stage of the development of the mobile communication system, the mobile subscriber international number (MSISDN number) is used to uniquely identify the mobile subscriber, and the existing mobile communication information systems are also designed based on the MSISDN number. Therefore, each mobile communication device in the existing mobile communication system, such as a mobile switching center (MSC), can identify the MSISDN number and provide corresponding services for it. [0003] However, with the proliferation of mobile users, there has been a shortage of MSI...

Problems solved by technology

[0015] It can be seen from the above process that when dealing with access number + virtual number calls in the prior art, it is necessary to add a special MSC on the basis of the existing communication system to handle the routing addressing of the virtual number, thus increasing the The complexity of system implementation also increases the cost of equipment

[0016] Additionally, by figure 1 It can be seen that the media flow between the calling user and the called user using the virtual number needs to pass through the MSC / VLR where the calling user is located, and then pass through the special MSC to reach the MSC / VLR where the called user is located, resulting in media The routing of the flow is circuitous, resulting in a large connection delay between the calling user and the called user
