Abstract

The present invention relates to an apparatus and a method for fast recovery to a certain radio access technology (rat). The mobile communication device supports a plurality of RATs and includes a first wireless transceiver, a second wireless transceiver, and a controller. The first wireless transceiver performs wireless transmission and reception to and from a first cellular network utilizing a first RAT. The second wireless transceiver obtains a non-cellular signal indicator. The controller determines whether the first RAT is a predetermined one of the plurality of RATs when the mobile communication device camps on the first cellular network, and if not, predicts whether there is a second cellular network available, which utilizes the predetermined RAT, based on the non-cellular signal indicator. In response to predicting that the second cellular network is available based on the non-cellular signal indicator, the controller further enables the mobile communication device to camp onthe second cellular network via the first wireless transceiver. According to the invention, faster and better mobile services can be provided for users of the mobile communication device, so that theuser experience is improved.

Description

[0001] cross reference [0002] This application claims priority to US Patent Application No. 16 / 427,462, filed May 31, 2019, which is hereby incorporated by reference. technical field [0003] The present invention relates generally to mobile communication, and more particularly, to an apparatus and method for fast recovery of a certain RAT among a plurality of Radio Access Technology (RAT) supported by a mobile communication device. Background technique [0004] With the growing demand for ubiquitous computing and networking, various wireless technologies have been developed, including cellular technologies (also known as RATs) and non-cellular wireless technologies. For example, cellular technologies include Global System for Mobile communications (Global System for Mobile communications, GSM) technology, General Packet Radio Service (General Packet Radio Service, GPRS) technology, Enhanced Data rates for Global Evolution (EDGE) technology, wideband code Wideband Code D...
