Abstract: Apparatus, and an associated method, for enhancing VoIP communication services at a selected QoS level in a radio communication system. Apparatus is embodied at a MAC (Medium Access Control) layer of the communication system by which selectably to cause retransmission and re-ordering of data communicated pursuant to effectuation of the communication service. A service request generator generates a service request that requests initiation the communication service in which data retransmission is effectuated at the MAC layer. And, a buffer is utilized at the MAC layer at which data is re-ordered, if necessary, to place the data in form for delivery to higher logical layers defined in the communication system.

Abstract: Apparatus, and an associated method, for providing a radio link layer control procedure to maintain the sensitivity of UDP-Lite-formatted data at an RLP (Radio Link Protocol), or other, layer. An indicator generator generates an indication of the sensitivity-type of data that is formatted at the RLP layer. An RLP packet is generated, including the sensitivity data indicator value, and sent to a receiving station. When received thereat, the value of the sensitivity data indicator is utilized and subsequent actions, whether to permit retransmission of the data in the event of erroneous-, or non-, delivery is made.

A medium access control identification code (MAC_ID) assigned by a base station from a MAC_ID space to each one of a plurality of mobile stations; wherein the MAC_ID is assigned in an ascending (or descending) order from the MAC_ID space for a first group of mobile stations, and wherein the MAC_ID is assigned in a descending (or ascending) order from the MAC_ID space for a second group of mobile stations.

Abstract: The present invention is related to a method and system for interlayer control where a Protocol Data Unit (PDU) is received from a lower protocol layer at a upper layer where the lower and upper layer are both involved in a retransmission function, a re-sequencing function, or both functions. The lower layer signals the upper layer for retransmission of a PDU when the retransmissions of that PDU have been exhausted and failed at the lower layer. The signaling scheme from the lower layer to the upper layer is an ABORT notification. This ABORT notification comes with associated parameters to indicate to the upper layer which PDU can be requested for retransmission from the upper layer.

Abstract: 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.

Abstract: The present invention is a system for distributing the reconnection attempts of multiple system users in a CDMA telephone system over a broad time window. The present invention allows either the base station or the mobile station to process data to determine an appropriate reconnect time. The data may include resource capability, priority, client connects pending, and timing and amount of data on pending connection requests. Using this data information, a more efficient reconnection scheme may be developed. The number of requests required to successfully connect can be reduced while increasing the utilization of resources and reducing the delay until connection. Under an intelligent reconnection scheme, the probability of system users attempting simultaneous reconnection is reduced, thus reducing the likelihood of reconnection collision.

Abstract: 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.

A process for controlling selection of MCS method to be used by a BTS (10) to transmit data packets over a forward shared channel to a MS (12) in accordance with the invention stores information at the BTS, the information containing MCS methods which may be selected to transmit data packets over the forward shared channel to the MS; receiving from the MS at the BTS a quality indication of transmission of data packets over the forward channel to the MS; and selecting a MCS method from a plurality of MCS methods which may be used to transmit data packets on the forward channel dependent upon the received quality indication.

Abstract: The invention is a system and a method in a system including a mobile station (MS), a group of active cells including a first serving cell (cell a) and a second target cell (cell b) and a controller of the active cells which switches forward link transmissions of data packets from the controller (BSC) through the first serving cell to the mobile station to forward link transmission of data packets from the controller through a second cell to the mobile station.

Abstract: The present invention is a system for distributing the reconnection attempts of multiple system users in a CDMA telephone system over a broad time window. The invention assigns a randomly initial wait time for each system user from a time window. After the initial wait time is assigned to a system user, any unsuccessful reconnection attempt by that user results in quadrupling the current wait time, until a maximum wait time window is reached. Once the maximum time window is reached, the system user continues to attempt reconnection every cycle of the maximum wait time until connection is maintained. By randomly assigning an initial wait time to each system user, the probability of system users attempting simultaneous reconnection is reduced, thus reducing the likelihood of reconnection collision.

The communication indicia is measured by a measurer and the measured values of the selected parameters are formed into a TVMAR report and returned to the network part.

Abstract: 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.
