[0005] Part B users should belong to Bureau 771 in District 021 in terms of administrative division, but because the logic has not changed, they originally belonged to Bureau 458 in District 025. Therefore, when dialing Bureau 771 in District 021, you need to add an area code, and it is a long-distance call; while dialing 458 in District 025 The telephone number of the bureau is a call from this bureau, and the administrative division does not belong to the 458 bureau of the 025 district, but the billing is the local charge, which causes unreasonable billing
[0006] 2. Caller ID display problem
[0007] The actual geographic location of part B users should belong to Bureau 771 in District 021. When dialing Bureau 771 in District 021, the user phone of Bureau 771 in District 021 will be displayed as a call from District 025, but the call to Bureau 458 in District 025 will be displayed. When calling, there is no area code before the caller ID number, which causes the difference between the caller ID and the actual administrative division, causing the unreasonable display of the calling number

Embodiment Construction
[0026] The present invention is described in detail below.
[0027] A kind of method of the same switching office of the present invention has a plurality of long-distance area codes based on the program-controlled exchange, such as image 3 As shown, its implementation steps are as follows:
[0028] 1) Configure the long-distance area code in the number management of the exchange. The default is 0, which means that the area code is not configured, and the default area code of the exchange is used. area code.
[0029] 2) Because the same exchange has different toll area codes, different number analysis selectors are configured for the users in each toll area code, and the user performs number analysis according to his own number analysis selector when calling.
[0030] 3) Add a local analyzer and a toll analyzer in the respective number analyzers, analyze the "office code" of users in this area in the local analyzer, and do not analyze the area code; in the toll analyzer, "t...

The invention is a method that the same exchange bureau based on program-controlled exchanger has many long-distance district numbers, including: in the number management of the exchange bureau, configuring a different number analyzing and selecting subsystem to each user in each region of long-distance district number, adding a local analyzer and a long-distance analyzer in each number analyzing subsystem, and in the local analyzer, only analyze user numbers in the corresponding district number region; in the long-distance analyzer, analyze long-distance district numbers together with bureau number and make a bureau calling mark; in a region of long-distance district number, when the calling user makes a trans-district call, according to his number analyzing and selecting subsystem, analyze the called number, and then according to the analyzed result, decide whether to search in the bureau. It utilizes the user analyzing and selecting subsystem to implement coexistence of many long-distance district numbers in the same exchange bureau, reducing operating cost.
Description
technical field [0001] The present invention relates to a method for having multiple long-distance area codes in the same switching office on a program-controlled exchange, in particular, it relates to a method based on a program-controlled exchange in which a plurality of different toll area codes can be flexibly configured in the same exchange to satisfy a A method for various needs when the exchange spans several different areas. Background technique [0002] At present, with the development of the telecommunication industry, the capacity of each switching office is gradually expanded, and the overall coverage area is also wider and wider. And along with the continuous division of urban areas, users in the same switching office in the same area may be divided into different urban areas, so one switching office has multiple long-distance area codes and it will appear in this case. [0003] like figure 1 As shown, if the two parts A and B originally belonged to the users ...
