摘要： Apparatus, and an associated method, that reduces the occurrence of generation of redundant requests for retransmission of packet-formatted data, formatted at a physical layer and at a higher-logical layer, such as at an RLP layer. An estimate of an appropriate delay period is formed. The estimate is responsive to communication conditions in the communication system. When a data packet appears to have been inadequately delivered to the RLP logical layer, a DELAY_DETECTION_WINDOW timer is caused to time out the delay period estimated by the estimator. The request for retransmission, generated at the RLP layer, is permitted, upon expiration of the timer if the data packet has not yet been successfully delivered to the RLP layer and the transmitter has not given up the data packet delivery.

摘要： Apparatus, and an associated method, having a packet zone list timer embodied at a mobile node operable in a packet radio communication system. The packet zone list timer provides hysteresis to reduce the possibility of a ping-pong effect when a mobile node is operated at, or crosses, a packet zone boundary. A timer value used by the packet zone timer is selected at the mobile node without the need for network-generated commands to notify the mobile node of the timer value. Comparisons are made at the mobile node, and determinations are made at the mobile node as to whether registration of the mobile node is required.

摘要： An approach is provided for supporting end-to-end Quality of Service (QoS) control. A QoS profile identifier is generated that maps to a QoS parameter. The identifier is transmitted over the radio communication system to an end station, wherein the end station determines the QoS parameter based on the received identifier. The approach also provides an alert mechanism in which the end station transmits an alert message upon detecting a deviation from the QoS parameter.

摘要： A method and apparatus for packet-data header decompression, particularly advantageous for use in connection with broadcast and multicast messages being transported through a radio telecommunication system operable according to the CDMA 2000 standard. When a mobile subscriber desires broadcast content from a content server, the mobile station sets up a PPP session for submitting the request and negotiating security protocols. When a subscription is granted, the mobile station receives broadcast content that has undergone header compression. In order to synchronize its decompressor, the mobile station receives a full header from a PDSN. The full header is preferably sent out on a periodic basis just for this purpose. The frequency of full-header transmissions by the PDSN is increased from a normal mode to a high full-header frequency (HFHF) mode upon receiving a request for a full header from a mobile station, but returns to normal-mode full-header transition frequency after receiving an ACK message from the requesting mobile indicating successful decompressor synchronization, or upon the expiration of a predetermined HFHF-mode maximum duration.
