Problems solved by technology

Additionally, CDMA devices typically do not support scanning for multiple CDMA networks available in the area, so if the user's normal CDMA provider is not available, the user will not be aware of other locally available CDMA networks
Thus, especially in dual-mode or multi-mode user equipment, the ability to easily connect to or acquire local signals is limited

Embodiment Construction

[0017] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or aspect described herein as "exemplary" is not necessarily to be considered preferred or advantageous over other embodiments or aspects.

[0018] The presently disclosed methods and apparatus provide signal scanning in a user device that scans multiple air interfaces, allowing users to more quickly connect to operators regardless of location. Specifically, a wireless user can scan a location for available service providers or carriers from multiple air interfaces. Accordingly, the device is configured to scan one air interface first, then the second, and so on. In one particular aspect, CDMA and UMTS channels can be searched, presenting the user with all signals found in one location, allowing the user to immediately acquire a service plan and get connected without the need for roaming.

[0019] First, it should be pointed out that the techniques disclosed ...

Abstract

Methods and apparatus for signal scanning and acquisition for multiple-air-interface devices are discussed. In particular, scanning of a location for signals from one or more local service providers is carried out, wherein scanning is operable to detect signals based on at least a first air interface and a second air interface, such as CDMA and UMTS, respectively. A list of local service providers detected from the scanning is assembled to allow a user to select a connection to at a local service provider from the list. Thus, a user is afforded the ability to see all service provider signals in the location, for all bands and air-interfaces supported by the modem on a user's multiple-air-interface device. The user may therefore acquire connection more easily without having any prior knowledge about the area or its service providers, and regardless of the type of air interface originating the local signals.

Description

[0001] Claim priority under 35 U.S.C. §119 [0002] This application claims priority to Provisional Application No. 61 / 141,370, filed December 30, 2008, entitled "AUTOSCANSIGNALACQUISITIONFORDUAL-AIR-INTERFACEDEVICES" and assigned to the assignee of this application, which is expressly incorporated herein by reference Incorporated into this article. technical field [0003] The present invention relates generally to wireless communications, and more particularly to signal scanning and acquisition for multiple air interface devices. Background technique [0004] Wireless communication users often need wireless communication access in various random environments. For example, a wireless user may step off an airplane anywhere in the world and wish to connect to a local signal. However, there are currently various limitations to this functionality. For example, in the case of a dual air interface device capable of communicating with Global System for Mobile Communications (GS...
