Abstract: The disclosed multiple alerting service, provided through a mobile communication network, is controlled by the subscriber's home location register (HLR) and/or the mobile switching center (MSC) provisioned as the home MSC for the pilot number. A call to the pilot number triggers access of the subscriber record in the HLR, and the home MSC launches call legs to the subscriber's mobile station and one or more member numbers. An alternate available member number may be substituted, for example, if a station of one of the initial numbers is unavailable. If a call leg is answered, the home system completes the call to that leg and releases the other call leg(s). If completion to a group station is not possible, the home system redirects the call to an alternate termination, based on the subscriber's record, for example, to a voice mailbox associated with the pilot number in the home system.

Abstract: Systems and methods for exchanging a short message service (SMS) message between networks operating in accordance with different standards. An intermediary system operates between a first network operating in accordance with a first standard and a second network operating in accordance with a second standard. A routing information request for an SMS message is received, at the intermediary, from the first network and the intermediary sends, in response to the routing information request, an acknowledgement message to the first network. The SMS message is thereafter received at the intermediary and an acknowledgement of receipt of the SMS message is generated in the intermediary and then sent to the first network. The SMS message is then sent from the intermediary to the second network. In a preferred embodiment, the intermediary is an entity distinct from the first and second networks, but operates as a virtual MSC from the perspective of the first and second networks.

Abstract: A mobile communication system that proposes a new charging principle, according to which the roaming leg is paid entirely by the party who forwards the call to a mobile subscriber. In an exemplary embodiment, the call is first routed to the exchange of subscriber B, who has forwarded his calls. After determining that the call is to be forwarded to a mobile subscriber C, the exchange routes the call to the gateway mobile switching center (GMSC) capable of making interrogations to the home location register of subscriber C. When the charging record for the call is generated, the called subscriber B is charged for the leg between the GMSC and subscriber C. Thus, subscriber C does not have to pay for calls addressed to subscriber B. To minimize the call costs to subscriber B, as direct a route as possible is preferably used on the leg between the GMSC and subscriber C.

The congestion avoidance logic determines a cluster threshold that corresponds to traffic load distribution among the critical clusters. Additionally, the congestion avoidance logic selectively grants the bandwidth request based upon the determined cluster threshold.

Abstract: Operation of a synchronization network that includes a number of nodes and reference clock distribution logic includes, at each of the nodes, storing a table that represents a most recent status of the synchronization network. Reference clocks are then distributed to each node in the synchronization network. If a change in synchronization status occurs at a node in the synchronization network, this change is detected.

Abstract: An elliptical satellite communication system including a constellation of satellites which orbit the earth at a height less than that necessary for geosynchronous orbits but which simulate the characteristics of geosynchronous orbits. The satellites' velocity near the apogee portion of their orbit approximates the rotational velocity of the earth, and during that period appear to hover over the earth. The ground stations on the earth always communicate with a satellite at or near its apogee, and hence that satellite appears to the ground station to hover over the earth. During the times when the satellite is outside the apogee portion, its communication is shut off to prevent any possibility of interfering with geosynchronous satellites and its power supply is used to charge a battery on the satellite. Thus, the power supply of the system can be reduced by an amount equivalent to the percentage of time the satellite is not used.

In one embodiment communications are handed over from a first satellite to another satellite when the first satellite is no longer at the highest elevation angle of visible satellites. In another embodiment, handover occurs when the first satellite drops below a minimum elevation angle.
