  • Apparatus and methods for facilitating tune-away operations in wireless communications systems
    Patent number: 9468010
    Abstract: Access terminals are adapted to facilitate tune-away operations in situations in which multiple subscriptions are employed. According to one example, an access terminal performing an acquisition procedure for a first subscription may suspend the acquisition procedure to obtain a paging message for a second subscription. The access terminal can tune away from the first subscription to the second subscription and monitor for a mobile-terminated page. After a mobile-terminated page associated with the second subscription is received and processed, the access terminal may resume the acquisition procedure for the first subscription. Other aspects, embodiments, and features are also included.
