Abstract: The present disclosure presents methods and apparatuses for improved tune away in dual-SIM, dual-standby user equipment (UE) in a wireless environment. For example, in an aspect, the present disclosure presents a method of improving active calls in a wireless environment, which may include establishing an active call on a first subscription associated with a first subscriber identification module (SIM) in a multi-standby user UE. In an additional aspect, such example methods may include limiting one or more idle mode procedures of a second subscription associated with a second SIM in the multi-standby UE to non-critical idle mode procedures. Furthermore, in some examples, the one or more idle mode procedures may include cell reselection procedures.

Abstract: Signals of different cells in a cellular wireless communications system are observed during associated intervals to predict a signal behavior in future. A target cell is selected by observing over time signal characteristics of potential target cells. Thereafter a target cell is selected by using the observed characteristics to predict which potential target cell will in future satisfy certain criteria.

Abstract: Methodologies for alerting a user to his or her location using terrestrial wireless signals are included. The methodologies include a method for alerting a user to his or her position relative to a predetermined location in response to a unique identifying signal from a terrestrial base station as well as a navigation method based upon one or more uniquely identifying signals from one or more terrestrial base stations positioned along a desired route. Also disclosed is a mobile terminal, for example, a mobile telephone, that is adapted to alert a user as to his or her location and aid in navigating the user through a selected route in response to the position of the mobile terminal relative to one or more terrestrial base stations.

Abstract: Cell reselection comprises monitoring a first indicator indicative of a signaling level of the serving cell, and monitoring second indicators, each indicative of a signaling level of one of plural potential target cells. A timer associated with a potential target cell is initiated when the respective second indicator indicates that the signaling level of the potential target cell is better than the signaling level of the serving cell. Each timer has an associated expiry, and, if at least one timer has been initiated by the expiry of another initiated timer, then, after delaying for an additional period after at least the first timer has expired, a target cell is selected from the potential target cells. The target cell is selected that has a second indicator which indicates that the signaling level of the respective target cell is better than the signaling level of the serving cell.
