Problems solved by technology

Since the user does not know that roaming billing has started, more roaming charges may be incurred, affecting user experience;
[0005] 2) Some customized terminals (TD-LTE, TD-SCDMA, and GSM three-mode support in domestic scenarios; TD-LTE, FDD LTE, WCDMA, and GSM four-mode support in international roaming scenarios) are reselected / redirected to other overseas operations During business hours, mode switching did not occur, and the terminal still only supports domestic standards and frequency bands, resulting in the terminal being unable to use the non-domestic standards and non-domestic frequency bands of the network in the roaming area.

Embodiment Construction

[0043] In the embodiment of the present invention, after the terminal camps in the target cell, it judges the PLMN ID of the target cell; the terminal determines that it is already outside the country according to the judgment result of the PLMN ID; Judging the working status, and performing corresponding mode switching operations and attaching operations to the target cell according to different judgment results; wherein, when the terminal determines that it is already outside the country, or when the terminal receives the target cell After the sender attaches and receives the message, it executes the mode switching operation; the working state is used to indicate that the terminal is in an idle state or a connected state.

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The invention discloses an international roaming processing method. The method comprises that after that a terminal become resident of a target cell, a public land mobile network (PLMN) ID of the target cell is determined; the terminal determines an oversea state of itself according to a PLMN ID determination result; and the terminal determines a present working state of itself, and executes corresponding mode switching operations as well as target cell attaching operations according to the different determination results. When the terminal determines to be in the oversea state, or after that the terminal receives an attachment reception message from the target cell, the mode switch operation is executed. The working state represents that the terminal is in an idle or connected state. The invention also discloses a device for realizing the method and a terminal.

Description

technical field [0001] The present invention relates to international roaming technology in the field of mobile communication, in particular to a processing method, device and terminal for international roaming under the scene of network configuration peer-to-peer public land mobile network (EPLMN). Background technique [0002] When an LTE terminal is roaming across the border and selects a network, because the Public Land Mobile Network (PLMN) IDs of the coverage network on both sides of the border are different and not related to each other, as the signal of the original resident network gradually weakens, the terminal will eventually leave the network first. The original resident network, and then re-search the resident network for resident. This off-network-research process will cause the user to be in a "no service" state for a long period of time, and the re-resident network cannot be specified by the original operator. [0003] In order to improve users' network sel...
