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 translation: 无线电链路协议（RLP）通信信道中的对等体协商接收队列中不活动窗口的大小。 窗口大小可以是包括在RLP_BLOB中的参数。 接收队列控制器可以接受建议的大小，或者可以返回不同的非活动窗口大小。 定义了一个序列范围内比较运算符，例如，IN_RANGE（SEQ，LO，HI），它以三个序号作为输入，并返回一个布尔指示，其中一个输入是否在由另一个定界的序列号范围内 两个输入。 比较是对序列空间进行模数化。 接收者通过向操作者传递数据帧的序列号，L_V（N）指针减去活动窗口大小和（L_V（N）-1）来确定接收到的数据帧是否处于非活动窗口内。 协商的非活动窗口允许超过序列空间的一半的活动窗口，这可能会阻止高数据速率应用中的发射机队列停顿。

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.

Abstract: A radio base station performs reverse link rate control in a wireless communication network by “stealing” bits on a forward common power control channel. The forward common power control channel is divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots. The radio base station may dynamically select power control slots depending on user demand to be used for reverse link rate control.

Abstract: Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

Abstract: Systems and methodologies are described that facilitate improving session initiation protocol based registration of a mobile device and an IP multimedia subsystem in wireless communications. The mobile device discovers one or more SIP servers (e.g., proxy call session control functions) that are available. The mobile device issues a ping message to each discovered server in parallel to determine reachability. Based at least in part on measured round trip times associated with the ping messages, the mobile device initiates registration procedures with at least one server.
