Systems and methods for individual telephone numbering assignment and administration in a telecommunications network are disclosed. Particularly, the invention relates to the concept of acquiring individual telephone numbers instead of acquiring a block of telephone numbers from an administration agency. According to disclosed embodiments, the system and method allow a carrier to request an individual telephone number from a numbering administrator. The numbering administrator verifies that the carrier is authorized to request an individual telephone in a particular geographic area. If the carrier is authorized, the numbering administrator obtains an individual telephone number from its database and provides it to the carrier. The carrier initiates an intra-carrier assignment with an administrative agency to get the individual telephone number assigned to it. The administrative agency processes the assignment activation request, and upon completion of the addignment process, notifies all carriers that the individual telephone number is assigned to the requesting carrier.

An IP telephony system obtains control over a group of telephone numbers that can be assigned to its customers' telephony devices under a contract with a first local exchange carrier that originally controlled the group of telephone numbers. The first local exchange carrier assigns one or more location routing numbers to the group of telephone numbers, and the one or more location routing numbers are for the exclusive use of the IP telephony system. The one or more location routing numbers are then recorded against the group of telephone numbers in a local number portability database. Other exchange carriers are then caused to route calls directed to the any telephony number associated with the one or more location routing numbers directly to the IP telephony system. As a result, a second local exchange carrier can terminate telephony communications directly to the IP telephony system, bypassing the first local exchange carrier.

A network upgrading-adaptive telephone number upgrading method and device for a wireless terminal are provided. The solution relates to the field of wireless communication. An initialization unit of a terminal device acquires telephone numbers to be upgraded, and backs up the telephone numbers for use during recovery of the telephone numbers; the initialization unit of the terminal device acquires storage positions where the telephone numbers to be upgraded are stored; a number upgrading unit of the terminal device acquires number upgrading rules from a network side through the wireless terminal, and upgrades the telephone numbers in the storage positions according to the number upgrading rules; and a number writing unit of the terminal device covers the telephone numbers in the storage positions with the upgraded telephone numbers. The problem that the telephone numbers of the wireless terminal or the terminal device cannot be adaptively upgraded after a network is upgraded is solved, and beneficial effects of adaptively upgrading the telephone numbers, improving user experiences and reducing a risk after the network upgrading of an operator are achieved.
