Abstract:
Various examples include methods for assisting Global Positioning System (GPS) applications using a Long Term Evolution (LTE) subscription on a wireless communication device. Various example methods may include determining whether positioning information can be obtained from a first network associated with the LTE subscription, obtaining the positioning information from the first network through the LTE subscription in response to determining that the positioning information can be obtained from the first network, translating the positioning information into a format recognizable to a GPS application executing on the wireless communication device, and providing the positioning information to the GPS application.
Abstract:
Methods and apparatus for wireless communication are provided. In one aspect, a method of wireless communication comprises receiving a first resource request including a first interval for at least one timing-priority task associated with a first radio access technology and a second resource request including a second interval for at least one timing-non-priority task associated with the first radio access technology. The method comprises granting the first resource request and reserving the first interval for the at least one timing-priority task associated with the first radio access technology. The method comprises receiving at least a third resource request including a third interval for at least one timing-priority task associated with a second radio access technology. The method comprises granting the third resource request and reserving the third interval for the at least one timing-priority task associated with the second radio access technology when the first interval and the third interval do not overlap.

Abstract:
Various embodiments provide methods implemented in a mobile communication device (e.g., a multi-RAT communication device) for maintaining at least one separate RGS value for each of a plurality of RATs operating on the mobile communication device. Specifically, a device processor on the mobile communication device (e.g., a crystal oscillator manager) may maintain a separate, up-to-date RGS value for each of the plurality of RATs and may associate each of the plurality of RATs with their respective RGS values. By keeping track of the plurality of RATs' respective RGS values, the device processor may ensure that an appropriate RGS value is used to facilitate each RAT's individual operations, such as acquisition/re-acquisition operations, sleep scheduling calculations, and handover/inter-RAT measurement operations. As a result, various embodiments may improve the performance of each RAT and the overall performance of the mobile communication device.
Abstract:
Various embodiments for improving acquisition of services in multi-SIM mobile devices by using modified priorities for radio access technologies (RATs) in partial out-of-service conditions include determining when a first radio access technology (RAT) within a plurality of RATs begins to use a shared resource within the multi-SIM mobile device that is configured to be utilized by the plurality of RATs, determining whether a second RAT within the plurality of RATs was in-service or out of service at the time when the first RAT began using the shared resource, calculating a modified priority value for the second RAT in response to determining that the second RAT was in-service at the time, and determining an order for subsequent scanning for the services by the plurality of RATs based on the calculated modified priority value for the second RAT when the second RAT in-service at the time.
Abstract:
Methods, systems and devices are providing for managing quad SIM functionality on a mobile device. The method includes maintaining active in a data traffic state on a first radio frequency (RF) chain of the mobile device a first subscription of a first SIM. Also, maintaining active in a slotted idle state each of a second SIM subscription, a third SIM subscription and a fourth SIM subscription on a second RF chain of the mobile device. The slotted idle states enabling the subscriptions to monitor pages in their paging channel slots. The method may include switching the third and fourth subscriptions to the first RF chain in response to the second subscription exiting the slotted idle state. The first, subscription may operate with tune away support while the third and fourth subscriptions operate in slotted idle state together on the first RF chain.
Abstract:
Various embodiments include multimode communication devices and methods for managing usage of radio access technologies (RATs). In various embodiments, the multimode communication device may prevent scanning for a signal of higher priority RATs when a communication link is established with a lower priority RAT and the multimode communication device determines that the device is stationary. Signal characteristics of the communication link and/or other resources that can detect when the multimode communication device has moved may be monitored. In response to a change in signal characteristics or another indication that the multimode communication device has moved, scanning of higher priority RATs may be reactivated.
Abstract:
Various embodiments include methods for a multi-subscription wireless communication device to obtain caller identification (ID) information for a call coming in on a first subscription while on a call on a second subscription. In various embodiments, when the second subscription is supporting a voice call and a page message for the first subscription is received from a network, the wireless communication device may exclude one or more fields from a page response message from the first subscription to the network, blindly accept a proposed service option sent by the network, and receive caller ID information from the network. In some embodiments, one or more fields from a page response message may include at least one of an additional pilots field and an alternate service option list. Receiving caller ID information from the network may be performed when the first subscription cannot support a proposed service option sent by the network.
Abstract:
A method for channel hashing on a mobile communication device includes: performing a first channel hash on a first channel list; determining whether a hash channel selected by the first channel hash is the same as a serving channel to which the mobile communication device is latched; in response to determining that the hash channel selected by the first channel hash is not the same as the serving channel, generating a second channel list by removing one or more channels from the first channel list; and performing a second channel hash on the second channel list.
Abstract:
Various embodiments provide methods, devices, and non-transitory processor-readable storage media for mitigating the risk of delayed connection or call failure during base station handover by preventing single radio long term evolution (SRLTE) communication devices from dropping Mobile Termination (MT) paging messages due to paging channel mismatches (e.g., mismatches between the Walsh codes used for different paging channels).
