20150038154 | Fair Instantaneous Conflict Resolution Among N Periodic Contenders - The various embodiments include methods for managing how a multi-SIM-multi-standby (MSMS) communication device that is accessing an arbitrary combination of multiple telephony networks processes paging collisions. The embodiment methods promote the control of the paging block rates for two or more subscriptions, in which a subscription's paging block rate is the subscription's number of blocked pages during a certain time multiplied by the subscription's discontinuous reception cycle. In the various embodiments, an MSMS communication device may implement a fair paging conflict resolution algorithm to keep each subscription's paging block rate approximately equal over time. | 02-05-2015 |
20150092611 | Multiple SIM Multiple Network Diversity For Enhancing Call Connectivity - Methods and devices are disclosed for establishing a second call during a first call on a multi-SIM communication device. A quality of the first call between a calling party and a called party using a first subscription for a first network may be determined to be degrading. Network alternatives may be provided for establishing the second call in response to determining that the quality of the first call is degrading. One of the network alternatives may be selected based on an order of suitability for originating the second call. A notification to the called party using information associated with calling party and the second call may be provided before the second call is originated. The information associated with the second call may identify the calling party to the called party before the second call is originated. | 04-02-2015 |
20150126187 | System and Methods for Cooperative Network Acquisition on a Multi-SIM Wireless Device - Methods and devices are disclosed for enabling efficient service acquisition on multiple SIMs of a multi-SIM wireless communication device. After both SIMs have lost service, or after initial power up of the wireless device, the wireless device may detect radio frequency channels associated with wireless networks of all SIMs, and determine whether the strongest received radio frequency channel matches a preferred network of any SIM. Upon detecting a match, the wireless device may awaken that SIM and automatically camp that SIM on cell of the matched radio frequency channel. In this manner, the wireless device may avoid repetition typically involved in acquiring service on multiple SIMs. | 05-07-2015 |
20150349836 | TEMPERATURE CONTROL AT POWER AMPLIFIER WITH TRANSCEIVER SWITCHING - A wireless communication device includes: a first communications unit configured to communicate with a first communication network; a second communications unit configured to communicate with a second communication network; a control unit configured to control operation of the wireless communication device; and one or more temperature sensors configured to sense operating temperatures of the first communications unit and the second communications unit and provide temperature signals to the control unit. In response to a determination that an operating temperature of the first communications unit conducting a first call exceeds a predetermined threshold temperature and an operating temperature of the second communications unit does not exceed the predetermined threshold temperature, the control unit is configured to cause the first call on the first communications unit to be switched from a first transceiver chain in the first communications unit to a second transceiver chain in the second communications unit. | 12-03-2015 |
20150373667 | METHOD TO REDUCE PAGE MISSES IN MULTI-SIM USER EQUIPMENT BY SPLIT ACQUISITION - Systems and methods are described for acquiring a first radio access technology (RAT), by segmenting an acquisition process of the first RAT into a plurality of chunks; executing a first chunk of the acquisition process; executing at least one portion of a paging process for paging a second RAT after the first chunk has been executed and before a second chunk is executed; and executing a second chunk of the acquisition process. Each of the plurality of chunks includes a portion of the acquisition process. | 12-24-2015 |
20160050590 | System and Methods for Improving Intra-frequency Cell Reselection on a Wireless Communication Device in Connected Mode - Methods and devices for enabling improved cell reselection procedures on a wireless communication device with a first SIM is camped on a serving cell of a first network may include receiving a list of neighbor cells from system information that is broadcast in the serving cell, and performing signal measurements associated with the listed neighbor cells and the serving cell, and, based on the signal measurements, identifying neighbor cells that satisfy selection criteria. The wireless device may calculate ranking criteria for the serving cell and the identified neighbor cells, and determine whether an inter-frequency neighbor cell has a highest ranking criteria among all of the ranked cells. Upon determining that an intra-frequency neighbor cell has the highest ranking criteria, the wireless device may start a reselection timer and also start decoding the system information that is being broadcast in the intra-frequency neighbor cell that has the highest ranking criteria. | 02-18-2016 |
