20140099953 | Apparatus and Method for Wireless Device Connectivity Upon Radio Link Failure - An apparatus and method for improving the connectivity when a radio link failure occurs is disclosed. The method includes detecting, by a user equipment (UE), a radio link failure to a first radio network controller (RNC) and receiving an information message from a second RNC. The method further includes determining whether the first and second RNCs have interface connectivity between them. If the first and second RNCs have interface connectivity between them, performing a connection recovery procedure with the second RNC. However, if the first and second RNCs do not have interface connectivity between them, performing an initial connection procedure to establish a connection with the second RNC without performing a connection recovery procedure. | 04-10-2014 |
20140162651 | Mobile terminated call establishment during inter radio access technology (IRAT) re-direction - Mobile terminated call establishment during inter radio access technology (IRAT) re-direction. Handovers between different respective radio access technologies (RATs) may be performed (e.g., IRAT redirection procedure) such that a given wireless communication device may be in communication with a given RAT cell, and then switch from that RAT cell to another RAT cell (e.g., a target RAT cell). This transition may be from a 3G cell to a target 4G cell. During such a redirection procedure, there may be some instances in which the target RAT cell may not be available immediately, and a device can check back with the first/original RAT cell during the search for the target RAT cell. That is to say, there may be some duration of time during the search for the target RAT cell in which that particular cell may not be available, and the device checks for pages in the first/original RAT cell. | 06-12-2014 |
20140204817 | Methods and Apparatuses for Increased Battery Performance in Networks with Different DRX Cycles - A system includes a processor and a memory connected with the processor, the memory to store logic. A DRX module also connects with the processor. The DRX module alternatively provides both a CS DRX cycle length and a PS DRX cycle length observed from network configuration. The processor executes the logic stored in the memory to instruct the DRX module to use a longer of a CS DRX cycle length or a PS DRX cycle length. | 07-24-2014 |
20140256318 | BATTERY CONSERVATION WITH IDLE MODE SIGNALING REDUCTION - Systems and methods are provided that may reduce the battery consumption footprint of a user equipment (UE) in a communications network, such as an LTE network. When a UE is in idle mode, when Idle Mode Signaling Reduction (ISR) is active in the communications network, and when the coverage area of the communications network, such as the LTE network, overlaps with the coverage area of one or more legacy radio access technology (RAT) networks, such as 2G and 3G networks, a module within the UE allows the UE to solely monitor paging messages on the legacy RAT network. Allowing the UE to camp on a legacy RAT network instead of an LTE network to monitor for paging messages can result in lower battery consumption levels when compared to the UE camping on the LTE network. | 09-11-2014 |
20140349662 | ADVANCED CIRCUIT SWITCHED FALLBACK CONNECTION ESTABLISHMENT WITH IDLE MODE SIGNALING REDUCTION - Systems and methods are provided that may reduce the battery consumption footprint of a user equipment (UE) in a communications network, such as an LTE network, as well as reduce over the air signaling over the LTE network, and reduce call set-up latency for circuit switched fallback (CSFB) calls. When Idle Mode Signaling Reduction (ISR) is active in the communications network, and when the coverage area of the communications network, such as the LTE network, overlaps with the coverage area of one or more legacy radio access technology (RAT) networks, such as 2G and 3G networks, a module within the UE allows the UE to directly establish a CSFB call over one of the legacy RAT networks instead of initially servicing the CSFB call over the LTE network. | 11-27-2014 |

20150163827 | Apparatus and Method for Paging for Mutli-Standby Devices - An apparatus and methods for improving paging performance for multi-standby devices having multiple subscriber identity module (SIM) cards are disclosed. For example, one method includes determining, by a user equipment (UE), a paging collision between a first paging channel associated with a first subscriber identity module (SIM) card and a second paging channel associated with a second SIM card. The method further includes monitoring the second paging channel and monitoring a physical channel associated with the first SIM card and different than the first paging channel. | 06-11-2015 |
20150215216 | Call Connection Establishment Via Service Specific Access Control - A method and apparatus is disclosed to prioritize certain types of traffic, such as voice traffic or video traffic, to provide some examples, over other types of traffic, such as data traffic, to provide an example, within one or more of the cells during the period of high volume of traffic, for example, during the foreseeable and/or the unforeseeable events. The traffic within the communication network can be monitored and the prioritization of the traffic can be dynamically changed based upon the type and volume of traffic or the prioritization of the traffic can be preemptively changed based upon a foreseeable event. | 07-30-2015 |
