摘要： A conflict resolution center (130 FIG. 1) is used to manage and resolve resource allocation conflicts in communications system (100) including a number of semi-autonomous communications nodes (SACNs). SACN (110) operates semi-autonomously because SACNs cannot independently allocate and de-allocate resources but rather operate within the confines of at least one local neighborhood. SACNs (110) allocate and de-allocate resources locally based on local neighborhood information. A conflict occurs when at least two SACNs try to allocate the same resource. Conflict resolution center (130) resolves conflicts using a number of different procedures. When a conflict can be resolved, conflict resolution center (130) provides resource reallocation data to at least one SACN (110). When a conflict cannot be resolved, conflict resolution center (130) notifies a system administrator.
摘要翻译：冲突解决中心（130图1）用于管理和解决包括多个半自主通信节点（SACN））的通信系统（100）中的资源分配冲突。 SACN（110）半自主运行，因为SACN不能独立地分配和分配资源，而是在至少一个当地邻域的范围内运行。 SACN（110）根据本地邻域信息在本地分配和分配资源。当至少有两个SACN尝试分配相同的资源时，会发生冲突。冲突解决中心（130）使用许多不同的程序解决冲突。当冲突解决时，冲突解决中心（130）向至少一个SACN（110）提供资源重新分配数据。当冲突无法解决时，冲突解决中心（130）通知系统管理员。

摘要： A cellular communication system (10) requests from subscriber units (30) to volunteer for handoff when a call resource shortage is about to occur. The subscriber units (30) may volunteer to handoff to another cell (24) depending on whether any adjacent or neighbor cell (24) provides adequate signal strength for servicing the on-going call. If there is another adjacent or neighbor cell (24) which provides adequate signal strength, the subscriber unit (30) can volunteer for handoff to the other cell. The cellular communication system (10) may accept the volunteer handoff request, whereby the subscriber unit (30) volunteering for handoff is handed-off to the other cell (24). However, the cellular communication system (10) may deny the handoff request. If the handoff request is denied, the subscriber unit (30) may have to drop the call or try to locate another cell to handoff its call before a predetermined amount of time expires.
摘要翻译：当呼叫资源不足即将发生时，蜂窝通信系统（10）从用户单元（30）请求自愿切换。取决于任何相邻小区（24）是否提供足够的信号强度来维持正在进行的呼叫，订户单元（30）可以自愿地切换到另一小区（24）。如果存在提供足够的信号强度的另一相邻小区（24），则用户单元（30）可以自愿地切换到另一小区。蜂窝通信系统（10）可以接受志愿者切换请求，由此自愿切换的用户单元（30）被切换到另一小区（24）。然而，蜂窝通信系统（10）可以拒绝切换请求。如果越区切换请求被拒绝，则在预定时间期满之前，用户单元（30）可能必须丢弃呼叫或尝试定位另一个小区来切换其呼叫。

摘要： A satellite cellular communication system includes satellites in motion that project cells upon the surface of the Earth. These cells are in motion and pass over individual subscriber units (26) engaged in communications, thus requiring individual subscriber units (26) to perform handoffs as an active current cell (300) currently servicing them advances. Selection of a subsequent servicing cell requires evaluation of active neighboring cells. A pre-computation of candidate cells is performed in advance according to a cell activation schedule. Active neighboring cells of an active current cell (300) are evaluated and prioritized in advance of individual subscriber unit's need for them. A candidate handoff cell list is then delivered to a satellite (12). A candidate handoff cell list is broadcast to all individual subscriber units (26) located within active current cell (300) for use in handoff decisions.

摘要： A satellite (110 FIG. 1) is used to make channel allocations for SUs (120) in communications system (100). Satellite (110) operate within the confines of at least one subset of satellites. Satellites (110) allocate channels using a maximum cost list that is based on a cost function methodology. A list of potentially interfering antennas is determined using a cost function analysis. A list of active channels on each one the potentially interfering antennas is also established. Another list that includes a set of potentially interfering channels for each active channel is established. Cost functions are computed for each pair of active channels and its potentially interfering channels. These cost functions establish interference potentials for the available channels in the maximum cost list (400). Channels are allocated using the maximum cost list and interference potential thresholds. Cost functions are based on spatial isolation, spectral isolation, and temporal isolation.

摘要： A satellite communications system (10) provides for digital beamforming acquisition. The communications system (10) has an antenna configuration (20) for maintaining communications links with satellite networking equipment, and a signal processing system (30) for processing signals resulting from the communications links. A beamforming subsystem (40) dynamically forms traffic beams and overhead beams, wherein the overhead beams scan overhead areas of the satellite footprint. Overhead areas are defined by areas of the satellite footprint without active traffic channels. The beamforming subsystem (40) includes a channel database configuration (50) containing traffic channel input data and overhead channel input data. A beamforming processor (60) converts the input data contained in the channel database configuration (50) into traffic beams schedules and overhead beam schedules. An antenna management system (70) dynamically forms traffic beams and overhead beams based on the beam schedules.

摘要： In a satellite communication system (10), a subscriber unit (26) is assigned a communication channel (17). The channel is used in the present cell (54) as well as subsequent cells (54) as the cells move relative to the earth. The channel is assigned using a cost function which includes a distance factor and an isolation factor. The distance factor which is based on a geographic distance between the nearest use of an interfering channel and the subscriber unit's cell. The isolation factor includes an interference potential between two channels. As a result of this channel assignment process, channels become associated with the geographic location of the subscriber unit. Accordingly, subscriber unit communications on the same satellite are handed-off between cells using the same channel making hand-offs invisible to the subscriber unit (26). When a hand-off is needed to another satellite, the same channel may also be used, or a new channel assigned using the cost function.

摘要： In a communications system, an earth-based subscriber unit (40, FIG. 1) receives at least one communications beam (50, 60, FIG. 1) transmitted from one or more moving satellite communications nodes (10, 20). The earthbased subscriber unit evaluates which communications beam should be selected based on the power received (FIG. 2, 210), Doppler frequency shift (270), link quality, (290), interference level (300), and satellite and network specific parameters (310). By considering these factors, the earth-based subscriber unit selects the communications beam (50, 60) that will provide the optimum service and reduce the likelihood that an inter-satellite hand over of the call will be required while the call is in progress.
