Abstract:
ndrdCertain aspects of the present disclosure relate to techniques for improving a circuit switched fallback (CSFB) user experience. In aspects methods and systems for autonomously returning a user equipment (UE) from a 2G (2 generation)/3G (3 generation) network to an LTE (Long Term Evolution) network are provided. The UE may store a flag to note whether a current circuit switched (CS) call in the 2G/3G network is a result of a CSFB. The UE in response to detecting a termination of the current CS call in the 2G/3G network and determining that the terminated call was a CSFB call (e.g. from the status of the flag) may trigger a mobility mechanism to autonomously return the UE to the LTE network.
Abstract:
The present disclosure presents a method and apparatus for dynamically configuring a cell update message at a user equipment (UE). For example the method may include determining that a size of the cell update message at the UE is above a threshold value after a 'measured results on random access channel (RACH)' information element (IE) is excluded from the cell update message. Furthermore such an example method may include removing one or more IEs from the cell update message until the size of the cell update message is at or below the threshold value. As such dynamic configuration of a cell update message at a UE is achieved.
Abstract:
Un procedimiento para configurar dinámicamente un mensaje de actualización de célula en un equipo de usuario, UE, (102), que comprende: determinar que un tamaño del mensaje de actualización de célula (108) en el UE está por encima de un valor umbral después de que un elemento de información, IE, "resultados medidos en canal de acceso aleatorio, RACH", se elimina del mensaje de actualización de célula (302); y eliminar uno o más IE del mensaje de actualización de célula hasta que el tamaño del mensaje de actualización de célula es igual o inferior al valor umbral (304), en el que el uno o más IE eliminados del mensaje de actualización de célula se seleccionan de una lista que comprende un IE "soporte para dos sistemas de DRX en URA_PCH y CELL_PCH ", un IE "canal físico compartido de enlace descendente de alta velocidad, HS-PDSCH, en CELL_FACH", un IE "soporte de operación de DRX de canal compartido de enlace descendente de alta velocidad, HS-DSCH", un IE "soporte de canal dedicado mejorado, EDCH, de enlace ascendente común", un IE "soporte de control de acceso al medio, MAC-i", un IE "soporte de operación de programación semipersistente, SPS", un IE "soporte de operación de recepción discontinua, DRX, de canal de control", un IE "valor START" para un dominio inactivo y un IE "causa de establecimiento".
Abstract:
An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call.
Abstract:
Disclosed are methods and apparatus for reducing page loss in a multiple subscription, multiple radio access wireless device, such as a dual SIM wireless device. The disclosed methodology and apparatus determine whether a conflict will arise between paging channel information received from at least two or more subscriptions from two or more radio access networks using a single receiver in the wireless device. The reception for paging channel information via the wireless receiver is switched to receive the paging channel information from a neighboring cell for one of the two subscriptions when a conflict is determined. By switching reception of paging channel information to another neighboring cell, the likelihood of page collisions between two subscriptions is reduced.

Abstract:
In a particular embodiment, a method includes sending a message from a communication device to a radio network controller. The message indicates that a data session has ended. The data session is supported by a wireless channel between the communication device and the radio network controller. After a time period following the sending of the message, a second message is selectively sent to the radio network controller. The second message indicates that the data session has ended. The second message is selectively sent based at least in part on whether a measurement indicates that data was communicated via the wireless channel during the time period.
