Example Embodiment

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] When the UE is powered on or in a roaming state, its first task is to find and register on the network first. Although the process of UE registration to the network is very short, it involves a series of complex signaling interaction processes. Since the signaling processing capability when the network is turned on and registered directly affects the user's normal use of the terminal, it is necessary to analyze the working status of the UE under this behavior and find a suitable way to optimize the network search process becomes the basic starting point of the implementation of the present invention.

[0034] The core technical solution of the present invention is to c...

Abstract

The invention discloses a network registration method of a multi-mode mobile terminal, which comprises the steps that: an access type used by the mobile terminal is confirmed; all the usable labels of public land mobile networks (PLMN) stored in the memory of the mobile terminal are retrieved by the mobile terminal and a PLMN label list is constructed; one or a plurality of PLMN labels that comply with the confirmed access type are selected from the PLMN label list by the mobile terminal and a second PLMN label list is set up newly for placing the selected PLMN labels; and the mobile terminal carries out network search operation one by one according to the PLMN labels selected from the second PLMN label list. In addition, the invention also discloses a network registration device of the multi-mode mobile terminal. With the technical proposal of the invention, the mobile terminal can carry out preferential search in the PLMN list that satisfies the access requirements of the mobile terminal when carrying out network search, thereby shortening network searching process and realizing the purpose of the rapid registration of the terminal to a network.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a network registration method and device for a multi-mode mobile terminal. Background technique [0002] With the development of mobile communication technology, mobile communication terminals have been widely used by more and more users, because the update speed of the system and the update speed of the mobile terminal are not synchronized in real time. Therefore, for a period of time to come, mobile terminals that support multi-mode access technologies will inevitably become the best choice in the market. The simultaneous existence of the second-generation communication technology (2G) and the third-generation communication technology (3G) satisfies the mobile terminal's ability to adapt to various access networks, and prevents users from wanting to use 2G access because of poor 3G coverage or because of 2G Insufficient functions and the disadvantage of constantly ch...
