Embodiment Construction

[0018] When an existing multimode wireless communication device is powered on for the first time and / or attempts to recover from an out-of-service (OOS) state, the device is configured to scan each frequency band used by each RAT supported by the device in an attempt to detect available wireless signals . However, the deployment of RATs and frequency bands is not universal. Accordingly, existing wireless communication devices perform service scans for supported RATs and frequency bands regardless of whether the RATs / frequency bands are deployed in the area in which the device is operating. For example, although TD-SCDMA is only deployed in China, current wireless communication devices that support operation on Time Division Synchronous Code Division Multiple Access (TD-SCDMA) networks scan for TD-SCDMA coverage even if they are operating in the United States. As another example, GSM is not deployed in Japan. However, current wireless communication devices that support GSM op...

Abstract

A method for reducing network service scan time by a wireless communication device is provided. The method can include the wireless communication device determining a location of the wireless communication device. The method can further include the wireless communication devices selecting a subset of RATs supported by the wireless communication device based at least in part on the location of the wireless communication device and on deployment mapping information. The selected subset can include only one or more RATs indicated by the deployment mapping information to be deployed in the location of the wireless communication device. The method can further include the wireless communication device performing a service scan for at least one RAT included in the selected subset. Any RAT of the RATs supported by the wireless communication device that is not included in the selected subset can be excluded from the service scan.

Description

technical field [0001] The described embodiments relate generally to wireless communication technologies, and more particularly to reducing network service scan times for wireless communication devices. Background technique [0002] New radio access technologies (RATs), such as Long Term Evolution (LTE), continue to be rapidly developed and deployed, providing faster data rates to support the capabilities of modern wireless communication devices. These new RATs are often co-deployed in areas of overlapping coverage with older legacy RATs. For example, long-term evolution (LTE) networks are developed and deployed in conjunction with second-generation (2G) networks, such as Global System for Mobile Communications (GSM) networks, and / or third-generation (3G) networks, such as Universal Mobile Telecommunications System (UMTS ) network) in the area of ​​overlapping coverage. However, the coverage area of ​​co-deployed RATs is often not co-extended. Furthermore, some RATs may b...
