Abstract

A method for performing an adjustment in a wireless communication device, comprising tuning the wireless communication device away from a first communication network for a first tune-away period to receive a first paging burst from a second communication network, and Tuning sequentially to a plurality of neighbor cells of the second communication network during the first tune away period and performing signal quality measurements on signals received from each of the plurality of neighbor cells.

Description

Background technique [0001] Wireless communication networks support communication for multiple users by sharing available network resources. Some wireless devices are configured to facilitate communication over two separate networks through two separate subscriptions. For example, a Dual Subscription Identity Module (SIM), Dual Standby (DSDS) device may include two SIM cards - one for the first subscription and a second for the second subscription, and be able to receive data from two different networks. services. [0002] DSDS mobile communication devices that support both Wideband Code Division Multiple Access (WCDMA) SIM and Global System for Mobile Communications (GSM) SIM must switch from the WCDMA SIM when the WCDMA SIM is in the Dedicated Channel (DCH) or Forward Access Channel (FACH) state. Move away to receive GSM paging bursts. Most GSM standby mode activity involves reception of one time slot from a Time Division Multiple Access (TDMA) frame. Some GSM activities...
