Problems solved by technology

[0007] First of all, if there are multiple types of users in a business group, since users of different types cannot be placed in the same user group, if a user of one user group initiates a call to a user of another user group in the same business group, it must Call the user's long number, and the cost of dialing a long number is much higher than the cost of dialing a short number (in many cases, a short number is even free), so even if a business group user calls a different type of user in the same group, an additional fee is required , increasing the economic burden on the commercial group
[0008] Secondly, since Centrex exists for each type of user, the operator function needs to be configured for each type of Centrex. On the one hand, multiple operators are required. On the other hand, these operators exist independently and cannot be unified together. It is inconvenient to search the numbers in the commercial group
Moreover, in addition to setting up the operator separately, the management platform and billing system of these Centrex must be set up separately, which increases the complexity of the internal management platform and billing system of the business group
[0009] Thirdly, this kind of Centrex based on a specific user is not conducive to extending to the virtual subscriber switch of multiple equipment providers, and cannot meet the WAC (WideArea Centrex) composed of different manufacturers, various user types, and cross-regional equipment proposed by domestic operators. ) needs

Embodiment 4

[0046]Embodiment 4 is that there is only one application server, and when a user outside the group dials a user in the group (incoming call from outside the group), the dialing method adopts dialing a large number, and the application server is not triggered during the process from the calling user to the called user. By adding a prefix (access code) in front of the called number, the called user triggers the call to the application server and uses the business logic on the application server. The application server adds a second prefix (or access code) before the number of the called user, indicating that the call has already triggered the application server, so as to prevent the called user from triggering once and then triggering it multiple times.

Embodiment 5

[0047] Embodiment 5 is when there is only one application server, and the calling user and the called user are not in the same business group (BusinessGroup; BG) (call between groups), the dialing method adopts dialing 9+large number, and through A prefix (access code) is added in front of the number, and the calling user triggers the call to the application server to use the business logic on the application server. The application server adds a second prefix (or access code) before the number of the called user, indicating that the call has already triggered the application server, preventing the called user from triggering it again after the calling user triggers it, and then routing the application server to the called party. user.

Embodiment 6

[0048] Embodiment 6 is the case where there are two application servers, and the calling user and the called user are not in the same business group (BusinessGroup; BG) (an intergroup call between two application servers), this situation is equivalent to the embodiment Three plus the situation of embodiment four. The dialing method adopts dialing 9+large number, and the calling user first triggers the call to the application server 1, and uses the business logic on the application server 1. The application server 2 is not triggered during the process from the calling user to the called user. By adding a prefix (access code) in front of the called number, the called user triggers the call to the application server 2, and uses the application server 2 on the business logic. The application server 2 adds a second prefix (or access code) before the called user number, indicating that the call has already triggered the application server 2, so as to prevent the called user from tr...

Abstract

This invention relates to virtual user exchanger method applied into communication network composed of one application servo and one flexible exchange, which comprises the following steps: a, defining one user property for above business set; b, mapping above property as interface codes; c, inserting the above codes in front of partner side; d, inserting the flexible exchange to the above application servo. This invention method can be applied in servo business logics between each user.

Description

(1) Technical field [0001] The invention relates to a method for realizing a virtual subscriber switch, especially a method for realizing a virtual subscriber switch in a fixed network, and a device for realizing the method. (2) Background technology [0002] A virtual subscriber exchange (also known as a centralized subscriber exchange service, Centrex) is a function of a digital program-controlled exchange. [0003] Centrex can provide business group (Business Group; BG) users with functions similar to private branch exchanges. Business group users do not need to purchase physical private branch exchanges. into a user group. [0004] The users in the above user group have two phone numbers, one long and one short: large number (also known as long number, Long Number), which is the direct dial telephone number of the outside line; small number (also known as short number, Short Number), which is the "Extension (Extension)" number, both long and short numbers are used. Th...
