Abstract: The quality of a broadcast stream is varied responsive to changes in the utilization of forward link air interface resources. The network monitors utilization of forward link air interface resources and dynamically changes the forward link air interface resources dedicated to the broadcast stream responsive to changes in the utilization of forward link air interface resources. The quality of the broadcast stream is scaled to the allocated forward link resources. The broadcast stream may include a layered content and scaling can be achieved by varying the number of layers transmitted over the air interface. The network may notify mobile stations in advance when changes in the quality of the broadcast will take place. When the broadcast stream originates with a mobile station, the forward link air interface resources may be limited by the quality of the broadcast stream transmitted over a reverse link channel from the originating mobile station.

Abstract: A mobile communication network includes a plurality of access nodes that can serve different roles in support of a communication session with a mobile station. An access node can serve as a connecting node that receives access requests the mobile station, as an anchor node to anchor a radio packet connection with a core network for the communication session; or as a primary node to store session information for the communication session. When the communication session is established, the anchor node for the communication session may select another access node to serve as the primary node. Session information can be stored at both the anchor node and primary node so that data can be delivered to the mobile station if either one of the anchor node and primary node are available. During a communication session, a connecting node receiving a connection request from a dormant mobile station may request session information from the primary node. The radio packet connection may also be moved to the connecting node.

Abstract: In a multicarrier CDMA system, a data stream is divided into two or more substreams and each substream is assigned to a different carrier. An RLP context is created for each carrier and the substreams are transmitted within a corresponding RLP context over a designated carrier. If a carrier is lost or dropped, the corresponding RLP context can persist after loss of the carrier and retransmitted packets tunneled to a different carrier.

Abstract: A hybrid test bed mixes simulated and actual wireless communication network entities in a real-time packet data simulation. In at least one embodiment, the test bed supports end-to-end simulation for a packet data application running on a mobile station simulator. The test bed provides a realistic assessment of that application's real-time performance by constraining packet data transmissions from a radio base station simulator to the mobile station simulator according to peak data throughput estimates and mobility event processing determined from a detailed wireless communication network simulation. Additionally, the test bed includes or is associated with a graphical display system providing real-time performance information.

Abstract: Two or more different sets of access parameters are stored in mobile station memory. When the mobile station sends an access message on the reverse access channel, it selects a set of access parameters based on the type of service. For high priority services, the mobile station selects a set of access parameters that reduces call setup latency. The network can change a selected set of access parameters by sending an access parameter message containing the updated parameter values. The access parameter message includes a priority field indicating the selected set of access parameters to be updated.

Abstract: A multicarrier CDMA system allows the number of carrier frequencies supporting a connection to be dynamically varied. The packet stream is divided into one or more substreams depending on the selected number of carrier frequencies and each substream is transmitted on a corresponding carrier frequency. The number of carrier frequencies is selectively varied during transmission of said packet data.

Abstract: Higher layer packet (HLP) framing information is transmitted across the air interface only as necessary, utilizing the Radio Link Protocol (RLP). In one embodiment, a new RLP control frame is transmitted between RLP data frames containing data from different HLP, demarking the boundary between the HLP. In another embodiment, a new RLP data frame contains framing information, and an indicator of that framing information. The new RLP data frame is transmitted only when necessary, e.g., when the RLP data frame includes a HLP boundary. When transmitting intermediate HLP fragments, conventional RLP data frames are used, wherein the entire payload is dedicated to user data, and the framing information is transmitted implicitly.

Abstract: Peers in a Radio Link Protocol (RLP) communication channel negotiate the size of an inactive window in a receive queue. The window size may be a parameter included in the RLP_BLOB. The receive queue controller may accept the proposed size, or may return a different inactive window size. A sequence number in-range comparison operator, e.g., IN_RANGE (SEQ, LO, HI), is defined that takes a three sequence numbers as input and returns a Boolean indication whether one of the inputs is within the sequence number range delimited by the other two inputs. The comparison is modulo the sequence space. The receiver determines whether a received data frame is within the inactive window by passing the operator the sequence number of the data frame, the L_V(N) pointer less the active window size, and (LV_(N)−1). A negotiated inactive window allows for an active window that exceeds half of the sequence space, which may prevent transmitter queue stalls in high data rate applications.

Abstract: A base station in a wireless communication network multi-codes a shared packet data channel using a continually changing set of spreading codes, and dynamically updates the transmission frequency of messages identifying the spreading codes to be used for that multi-coding based on tracking the net gain in data throughput for the shared channel that is obtained by transmitting such messages. In a 1xEV-DV network context, for example, a Walsh code in the defined Walsh code space that is not contiguous with the Walsh codes currently allocated to multi-coding the 1xEV-DV Forward Packet Data Channel (F-PDCH) generally remains unavailable for such use until an updated Walsh Mask Broadcast (WMB) message is transmitted to the mobile stations being served on the F-PDCH. The base station thus is configured to determine the frequency at which to send such messages and thereby make the unavailable codes available for multi-coding use.
