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.

Method and system for centrally exchanging terminal information over a meshed network

A method, system, and computer program product for providing communications services, including determining a type of communications service present in a communications session based on quality of service parameters assigned for the communications session; and adjusting the quality of service parameters based a different type of communications service requested. The types of communications services include real-time and non-real-time communications services.

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.

An approach for transmitting packets over a shared communication channel is disclosed. A satellite terminal (ST) () contains a processor that transmits a packet over a transmission slot of the channel using a contention protocol, such as persistent Aloha. The processor reserves an available transmission slot, which is maintained until expiration of a predetermined timeout period.

Method and system for providing efficient data transmission based upon a contention protocol

A state transition diagram is presented for a user's access terminal for a satellite telecommunication system, showing the state of the access terminal's mobility management software layer, in response to various stimuli and conditions as the user enters into and out of various modes of operations, including deactivation, activation and illumination of a dark beam of a spot beam that is a shared resource.

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.

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.
