Abstract: Systems and methodologies are described that facilitate and/or effectuate transmission of circuit switched voice over packet switched networks. The systems and methodologies provide for the receiving a first packet originating from access terminals and/or user equipment, determining within which hybrid automatic repeat request (HARQ) the first packet is received, ascertaining an amount of delay that is applied to the first packet before the first packet is forwarded into a core circuit switched network; and establishing a periodic time interval within which to convey subsequent packets that originate from the communicating access terminal and/or user equipment.

Abstract: Se describen t?cnicas para soportar la operaci?n con un enlace ascendente mejorado en estado inactivo. Un equipo de usuario (UF) puede enviar un pre?mbulo de acceso para acceso aleatorio mientras que en un estado inactivo puede recibir un mensaje que contiene recursos asignados al UF. Los recursos asignados se pueden seleccionar mediante un Nodo B desde un agrupamiento de recursos pre-asignados al Nodo 3 para el enlace ascendente mejorado. El UF puede enviar informaci?n (por ejemplo, informaci?n de planificaci?n y/o su identidad de UF) al Nodo E utilizando los recursos asignados. El UF puede recibir un reconocimiento de giro al UF con base en la identidad del UE. El UF puede permanecer en el estado inactivo y continuar utilizando los recursos asignados hasta que dejen de estar asignados. Alternativamente, el UF puede realizar la transici?n a un estado activo y ya sea seguir utilizando los recursos asignados o recibir una asignaci?n de nuevos recursos para el estado activo.

Abstract: En un sistema de comunicación inalámbrica en el que un usuario que utiliza un equipo móvil solicita una transferencia de celda de servicio de una celda fuente a una celda objetivo, el equipo móvil monitorea la autorización para la transferencia desde la celda objetivo. Al mismo tiempo, el equipo móvil puede descodificar los datos de ya sea la celda fuente o la celda objetivo. En la recepción de la autorización para la transferencia, el equipo móvil envía la confirmación de la transferencia a la celda objetivo.

Abstract: Systems and methodologies are described that facilitate common data channel resource usage report for receiving additional channel resources in a wireless network. An access point can initially receive a set of channel resources from a network controller for providing wireless network access to one or more devices. The access point can grant and/or deny requests for one or more of the channel resources from a plurality of devices and can feedback information to the network controller regarding the granting/denying. The network controller can determine a load on the access point based at least in part on the feedback information and adjust channel resource allocation based on the load. Thus/ where an access point has granted resources close to capacity to one or more devices, the network controller can provide additional resources to the access point based on received feedback information related to the granted resources.

Abstract: A base station can employ a shared resource, such as a control channel, for communication with a mobile device. The mobile device can be granted the exclusive access to the shared resource for a limited time. The exclusive access can be such that there is not a limit in message size that can be transferred across the shared resource. To improve operation, the exclusive grant can be applied until it is determined that appropriate packets are transferred.

Abstract: A method for providing in-order delivery of data packets during a handoff in a communications network, comprising: transmitting L 2 data packets partially processed prior to the handoff from a source network entity to a target network entity via the target network entity; and transmitting, by an Access Terminal, AT, new data packets to the target network entity, wherein the target network entity forwards the L 2 data packets to the source network entity and the source network entity sends all IP data packets constructed from the L 2 data packets to an Access Gateway, AGW, prior to sending the new data packets by the AT as well as a corresponding system.

Abstract: Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switched co mmunications. The de-jitter buffer methods and apparatus presented modify th e playback of packets dependent upon whether silence periods are detected in ter-sentence or intra-sentence to optimize voice quality in a communication system. In one example, a de-jitter buffer determines the length of at least one silence period associated with a plurality of received packets and dete rmines a time to transmit a portion of the packets based on the determined l ength of the silence period. In another example, a silence characterizer uni t performs this function.
