Embodiment Construction

[0033] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0034] As described in the background art, in order to solve the problem of slow network search speed in the 3GPP standard, the existing technology optimizes it. For example, for the public land mobile network PLMN that has been successfully registered, the mobile terminal will store it in the list of recently registered public land mobile network RRPLMN in chronological order, and the later the time, the higher the priority. In this way, compared with the 3GPP standard, the search speed has indeed been improved, but there is still the possibility of random selection, thereby increasing the number of search attempts. The more attempts, the longer it will take to successfully register to the network. .

[0035] In view of the above technic...

Abstract

The invention discloses a method for quickly searching for public land mobile networks. According to the method, a positioning function which existing smart phones commonly have is used, position information of a current mobile terminal is obtained and stored by the adoption of a recently registered public land mobile network (RRPLMN) list, then the distance between a current position of the mobile terminal and the geographical position recorded in the RRPLMN list is calculated, the public land mobile networks (PLMN) in the RRPLMN list are sequenced according to the principle that the smaller the calculated distance is, the higher the priority is, and finally people try to register a network according to the sequence of the PLMNs in the RRPLMN. On the situation that the mobile terminal moves away from an attribution network, time for successfully registering a new network is shortened as much as possible, and the probability that register is rejected when the mobile terminal registers the network is reduced to some extent.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for quickly searching public land mobile networks. Background technique [0002] PLMN (Public Land Mobile Network) is a network established and operated by the government or an operator approved by it to provide land mobile communication services for the public. This network must be interconnected with the public switched telephone network (PSTN) to form a communication network of the entire region or country scale. PLMN=MCC+MNC, for example, the PLMN of China Mobile is 46000, and the PLMN of China Unicom is 46001. With the rapid development of mobile communication technology in recent years, the old network has not yet fully covered, and the new generation network has begun to take shape, resulting in the coexistence of various network forms, such as the existing 2.5-generation GSM network and the new 3G network and the fourth-generation network. The LTE...
