Abstract: The present invention provides methods and apparatus for providing access priority in a MAC protocol of a communications system such as, for example, with respect to UMTS RACH. Particularly, the invention introduces several access priority methodologies including: (i) random chip delay access priority (RCDAP); (ii) random backoff based access priority (RBBAP); (iii) variable logical channel based access priority (VLCAP); (iv) UMTS-specific variable logical channel based access priority (VLCAP'); (v) probability based access priority (PBAP); and (vi) retransmission based access priority (REBAP). Each methodology associates some parameter or parameters to access priority classes in order to influence the likelihood of a remote terminal completing a successful access request to a base station.

Abstract: Un método para el uso en un receptor para detectar una señal de solicitud de acceso aleatorio transmitida por un transmisor, comprende los pasos de: determinar (504) si una intensidad de la señal de la señal de solicitud de acceso aleatorio, recibida sobre un canal de acceso aleatorio accesible por dos o más transmisores capaces de transmitir las señales de solicitud de acceso aleatorios respectivas, está por debajo de un valor del umbral de detección inicial, donde el valor del umbral de detección inicial corresponde a un valor con el cual el receptor es capaz de detectar la señal de solicitud de acceso aleatorio; determinar (512) si la intensidad de la señal de la señal de solicitud de acceso aleatorio es mayor que o igual a al menos un primer valor del umbral de potencia cuando la intensidad de la señal de la señal de solicitud de acceso aleatorio está por debajo del valor del umbral de detección inicial; e informar (514) al transmisor cuando la intensidad de la señal de la señal de solicitud de acceso aleatorio es mayor que o igual al primer valor del umbral de potencia de manera que el transmisor pueda incrementar la intensidad de la señal de la señal de solicitud de acceso aleatorio por medio de una primera cantidad predeterminada y retransmitir, estando la primera cantidad predeterminada relacionada con una diferencia entre el valor del umbral de detección inicial y el primer valor del umbral de potencia.

Abstract: A quality of service guarantee for voice and other delay sensitive transmissions within an Internet Protocol (IP) network is provided by identifying the IP network path utilized for IP packet transmission between source and destination edge devices and virtually provisioning IP network path bandwidth for priority voice traffic. Priority for voice packets and admission control of new voice calls (and other delay sensitive traffic) based on the remaining available capacity over the IP network path guarantees that high priority voice (and other delay sensitive traffic) meet stringent delay requirements. A Virtual Provisioning Server is utilized to maintain bandwidth capacity data for each path segment within the IP network and to forward the bandwidth capacity data to a Signaling Gateway. The Signaling Gateway determines whether to accept or reject an additional delay sensitive traffic component based upon available bandwidth capacity for an IP network path. The Signaling Gateway then signals the originating source edge device as to its determination to accept or reject. Quality of Service guarantees concerning acceptable delay and jitter characteristics for real-time transmission over an IP network are therefore provided without the need to directly signal the individual IP routers over which an IP network path is established.

Abstract: The present invention provides a method for use in a UMTS receiver of detecting a signal transmitted by a UMTS transmitter which includes determining whether the signal is greater than or equal to at least a first power threshold value when the signal is below an initial detection threshold value, and informing the transmitter when the signal is greater than or equal to the first power threshold value such that the transmitter can increase a signal strength of the signal by a first predetermined amount and re-transmit. In another aspect of the invention, a method for use in a UMTS transmitter of power ramping a signal transmitted by the transmitter and received by a UMTS receiver includes increasing a signal strength of the signal by a first predetermined amount when informed by the receiver that the signal is greater than or equal to a first power threshold value but below an initial detection threshold value, and re-transmitting the signal.
