摘要： Two types of contention channels are used to accommodate broadband packet data in a satellite communication network. A first contention channel is used by unsynchronized user terminals to access the system and request a traffic channel. The first contention channel is of a sufficient duration to accommodate a RACH message, as well as the timing uncertainty between user terminals within a given spot beam. A second contention channel is shorter in duration than the first contention channel, and is narrowband, so that more than one second contention channel may be transmitted within the bandwidth of the broadband traffic channels. The second contention channels are used by synchronized user terminals for transmitting packet RACH, or PRACH, messages. The more efficient nature of the PRACH channels accommodates the increased overhead associated with bursty packet data, without the capacity cost of the longer duration RACH channel.
摘要翻译：两种类型的竞争通道用于在卫星通信网络中容纳宽带分组数据。不同步的用户终端使用第一争用通道访问系统并请求业务信道。第一争用信道具有足够的持续时间以适应RACH消息，以及在给定点波束内的用户终端之间的定时不确定性。第二争用信道的持续时间比第一竞争信道短，并且是窄带，使得可以在宽带业务信道的带宽内传输多于一个的第二争用信道。第二争用信道由同步用户终端用于发送分组RACH或PRACH消息。 PRACH信道的更高效的性质适应与突发分组数据相关联的增加的开销，而不需要较长持续时间的RACH信道的容量成本。

摘要： An approach is provided for communicating in a meshed network including a first terminal and a second terminal. A request from the first terminal for obtaining address information of the second terminal is submitted to a hub. The hub generates a response including the address information and the context information that specifies capabilities of the second terminal. This arrangement has particular applicability to a satellite network (e.g., Very Small Aperture Terminal (VSAT) network) that provides data communication services.

摘要： Load is smoothed over multiple bearers in a given spot-beam for a TDMA wireless personal communication system, offering packet data communication services to individual user terminals in shared mode. Load can be smoothed over multiple bearers in a given spot-beam for a TDMA wireless personal communication system which allows maintenance of minimum service levels as a guarantee to individual connections as well as optimizing distribution of users to all available radio channels. It is possible to distinguish between whether a particular bearer is QoS-blocked or demand-blocked. Either a loose smoothing algorithm or a tight smoothing algorithm may be used for the load control operation based on the above dispensation.

摘要： An approach for minimizing response times in transporting traffic over a packet radio communication system is disclosed. A terminal transmits a packet resource request message that specifies user terminal information using a contention channel according to a prescribed protocol. A gateway station receives the packet resource request message and transmits an assignment message that specifies a channel assignment based upon the user terminal information, wherein the terminal is configured to transmit the packets over a channel is based on the channel assignment. This approach has particular applicability to a satellite communication system.
