Problems solved by technology

However, this model cannot be effectively combined with the actual user experience
For example, if the user is not moving, the blind search may waste power consumption; and when the user actually moves to an area covered by 4G / 3G, the timer does not time out and the user does not search in time.

Embodiment Construction

[0030] When the terminal device is turned on or powered on, and after cell reselection, it first searches for an available public land mobile network (Public Land Mobile Network, PLMN). After searching for an available PLMN network, it can obtain the corresponding cell service and realize cell camping.

[0031] In some embodiments, the terminal device will pre-save a PLMN list, in which multiple PLMN networks are arranged in sequence according to priority, as shown in the following table, PLMN1, PLMN2, and PLMN3 can be the names of operators, such as sprint, T -mobile etc.:

[0032] serial number PLMN priority 1 PLMN1 1(high) 2 PLMN2 2 (medium) 3 PLMN3 3 (low)

[0033] When a terminal device registers with a network, it can search for networks according to the priority in the PLMN list, and try to reside on a high-priority network.

[0034]If the terminal device has access to VPLMN (Visited PLMN, visiting PLMN), but the VPLMN is not t...

Abstract

The invention provides a method for triggering search of a high-standard network, which can automatically trigger terminal equipment to start background network search and try to reside in and register the high-standard network when detecting that Wi-Fi of the terminal equipment is disconnected, moved out of an elevator and moved to other positions with better signals.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a method and a terminal device for quickly searching a high-standard network. Background technique [0002] With the popularization of 4G networks, users have increasingly strong demands for data access speed. Due to the huge difference in 4G / 3G / 2G network architecture, in most scenarios, the link and Internet access speed of data services are 4G>3G>2G. Therefore, most ordinary users require terminal equipment to Reserve a higher network standard to meet faster access speeds. [0003] At present, in the 3GPP (3rd Generation Partnership Project, the third generation partnership project) agreement, there are three ways to switch the standard: Hand Over (switching, connection state), Redirection (redirection, connection state), Reselection (reselection, idle state) state). However, according to the configuration of the actual network, often in some...
