Establishing method for call between mobile switching center and boundary zone terminal or home located terminal

Abstract

The invention discloses a call establishment method of a mobile exchange center and a boundary region terminal as well as a adscription region terminal, the mobile exchange center is used to receive the call establishment request of the boundary region terminal calling the adscription region terminal connected in the local and transmitted by the local basic station controller, and establishes thecall, wherein, an included called number conformation module, which is used to ensure the true called number according to the call establishment request, so as to make the mobile exchange center to realize the correct establishment to calls. In the method above, firstly, the mobile exchange center ensures the true called number according to the call establishment request transmitted by the local basic station controller and connected in the local of the boundary region terminal calling the adscription area terminal; and then, the mobile exchange center establishes the call according to the true called number. The technical scheme of the invention is proposed to avoid the call false connection of the boundary region terminal calling the adscription region terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication networks, in particular to an MSC (Mobile Switching Center, mobile switching center) and a method for establishing a call between a border area terminal and a home terminal. Background technique [0002] There is a wireless coverage boundary area in the mobile communication network, and the boundary area will be covered by wireless signals of BSs (Base Stations, base stations) belonging to different MSCs. A mobile terminal in a border area may access a BS in an adjacent area due to wireless signal drift, and communicate through an MSC in an adjacent area. [0003] Such as figure 1 As shown, the two circles represent the coverage areas of BS wireless signals in A and B respectively. Currently, the mobile terminal is in the border area of ​​A. Since the border area is covered by the wireless signal of BS in B, and the wireless signal of BS in B in the border area is strong Based on the ...

Problems solved by technology

[0003] like figure 1 As shown, the two circles represent the coverage areas of BS wireless signals in A and B respectively. Currently, the mobile terminal is in the border area of ​​A. Since the border area is covered by the wireless signal of BS in B, and the wireless signal of BS in B in the border area is strong Based on the wireless signal of BS in A, then the mobile terminal will access the BS in B; however, the mobile terminal does not know that it is currently connected to the BS in B, when it calls the home, that is, the terminal in A, The dialed number does not carry an area code, and the MSC at B will connect the call to the terminal corresponding to the number at B, resulting in errors in calling and billing

[0004] To sum up, since the border area in the existing mobile communication network will be covered by BS radio signals belonging to different MSCs in adjacent areas, when the mobile terminal in the border area initiates a call as the calling party, the call may be wrongly connected, thereby Affect the work and life of end users
