摘要： A communication system (100) includes an aircraft (120) that acts as a repeater between ground equipment (101) and communication units (128) on the ground. The ground equipment (101) includes multiple base transceiver stations (104, 106, 108) that provide traffic channels, control channels, and access channels. The channels are all in a single beam (124) projected from aircraft (120). Relative loading on access channels is influenced by access class lists (200, FIG. 2) assigned to control channels. Access classes can be transferred from one list to another, or they can be removed from a list. Relative loading of traffic channels on the base transceiver stations is influenced by assigning different time offsets to base transceiver station so that calls can be transferred from one base transceiver station to another.

摘要： A multicast message is transmitted from an originating subscriber unit (110, FIG. 1) through a network of satellite communications nodes (120, 130, and 140) to a plurality of receiving subscriber units (150, 160, and 170). Each message is distributed through the network of satellite communications nodes (120, 130, and 140) and replicated at the node nearest to the receiving subscriber unit. Receiving subscriber units (150, 160, and 170) are mapped into geographic cells which allows a single multicast transmission to be transmitted from the satellite communications node to those subscriber units within the same geographic cell. Multicast groups and membership rules are established by the originating subscriber unit (110) through a service provider (180). A multicast session manager (185) manages the multicast session.

摘要： A CDMA cellular communications network (400, FIG. 4) includes one or more aircraft (410), which relay pilot channel and control channel signals between base transceiver stations (BTS's 406, 413) and subscriber units (401). Over the control channel, the BTS transmits a handoff candidate list to the subscriber units. The handoff candidate list identifies candidate BTS's to which the subscriber unit, theoretically, could hand off. In addition, the list indicates at which offsets the subscriber units should search for short codes transmitted by the candidate BTS's over the pilot channel. Based on the path length between the BTS, aircraft, and subscriber unit, the candidate BTS's actually generate their short codes at an offset that is equal to or earlier than the offset reported to the subscriber unit by some delta. In addition, the BTS's can impose a variable delay on the generated short code bits to compensate for variations in the path delay as the aircraft flies in its flight pattern.

摘要翻译： CDMA蜂窝通信网络（400，图4）包括一个或多个飞行器，410在基站收发台（BTS 406,413）和用户单元（401）之间中继导频信道和控制信道信号。 在控制信道上，BTS向用户单元发送切换候选列表。 切换候选列表识别用户单元在理论上可以切断的候选BTS。 此外，该列表指示用户单元将哪个偏移量搜索候选BTS通过导频信道发送的短码。 基于BTS，飞机和用户单元之间的路径长度，候选BTS实际上以等于或早于通过某个增量向用户单元报告的偏移量的偏移生成其短码。 此外，BTS可以对所生成的短码位施加可变延迟，以补偿飞行器在其飞行模式中飞行时路径延迟的变化。

摘要： A satellite communication system uses dual satellite coverage techniques to simulate the provision of full duplex communications in the system. Each subscriber (100) in the system communicates with two satellites (102, 104) that use complementary time division duplex (TDD) frame structures (50, 72) for communicating with the subscriber (100). In one embodiment, each satellite in the system performs a transition between a first TDD frame structure (50) and a second TDD frame structure (72) while travelling through a transition region (102) of an associated orbit (130). Preferably, the transition is performed gradually so that an abrupt reduction in system capacity is avoided. In another embodiment, individual orbital planes in the satellite system are dedicated for use with particular TDD frame structures. A subscriber thus communicates with one satellite in each of two planes during a connection.

摘要： A communications network is capable of using time division multiple access (TDMA) techniques, code division multiple access (CDMA) techniques, or a combination of both. A subscriber unit (30) makes a request for a traffic channel over a CDMA pilot channel or a TDMA broadcast channel. A satellite (20) or a base station (40) receives the request and determines whether to assign a TDMA or CDMA traffic channel. The downlink and uplink can have the same access scheme (e.g., TDMA) or different access schemes (e.g., TDMA on the uplink and CDMA on the downlink).

摘要： The present method provides for a session initiation protocol timing arrangement which facilitates instant communications in a packet data communication system (50). Each network server (15-25) sets a time out timer (92) which is coordinated with each of the downstream network servers. Network server (15), for example, sets a time out timer value which is selectable by the system operator. Subsequent network servers (20 and 25) then set the value of the time out timer to be that of the originating server (15) or client (10) less a fixed time such as one second. Further, a provisional message (118) is sent through the network to avoid expiration of the time out timer in upstream stages.

摘要： A communication system provides multiple wireless services, each potentially having a different information bit rate. A transmitter (400, FIG. 4) encodes (504, FIG. 5) relatively low rate data (430, FIG. 4) using code division multiple access (CDMA). The resulting spread data stream(s) (436, FIG. 4) are multiplexed and modulated (506, 508, FIG. 5) along with relatively high information rate, non-encoded data streams (440, FIG. 4) using a time division multiple access/frequency division multiple access (TDMA/FDMA) protocol. In other embodiments, the methods and apparatus of the present invention can be used in a CDMA only system, or in a system using a time division multiplexing/FDMA and time division multiplexing/CDMA. In one embodiment, the spread data streams are transmitted in timeslots (211-214, FIG. 2) and frequencies (201-204, FIG. 2) that are interspersed between timeslots and frequencies used for the high rate data. A receiver (600, FIG. 6) performs complementary demodulation (704, FIG. 7), demultiplexing (706, FIG. 7), and decoding (710, FIG. 7).

摘要： A method of increasing satellite communication quality by using a MEO satellite constellation (12) and a LEO satellite constellation (14) in combination with a decision algorithm which selects the appropriate constellation to route a communication signal through. The decision algorithm can be embodied in three ways: gateway based (18), individual subscriber unit based (22) and satellite based (12, 14). The MEO constellation (12) and LEO (14) constellation may be cross-linked, allowing for switching of service between satellites, as needed, during a communication session.
