A computer-implemented system () is provided that supports a high degree of separation between processing elements. The computer-implemented system () comprises a plurality of cells () residing on the computer-implemented system, where each cell () includes a domain of execution () and at least one processing element (); a separation specification () that governs communication between the processing elements (); and a kernel () of an operating system that facilitates execution of the processing elements () and administers the communication between the processing elements () in accordance with the separation specification (), such that one processing element () can influence the operation of another processing element () only as set forth by the separation specification (). In particular, the separation specification provides memory allocation, remote procedure calls and exception handling mechanisms.

Method for allocating memory to tasks without exceeding predefined memory requirements

Authorized intercepts of communications in a satellite communications system ( ) are performed, according to which a law enforcement agency (LEA) can request the intercept of communications to and/or from subscriber units (SUs). In one embodiment, an LEA intercept request causes an intercept order for a particular target SU ( , FIG. ) to be transmitted to one or more satellites ( , FIG. ), where the intercept order is stored in an intercept table ( ). Any communications traffic involving the target SU results in an intercept by a satellite, which routes a copy of the intercepted communications to the requesting LEA, either directly or via an associated intercept facility ( , FIG. ).

Authorized intercepts of communications in a communications system such as a satellite communications system ( ) are controlled. Each law enforcement agency (LEA) can only intercept communications to subscriber units (SUs) within its jurisdiction. In addition, the identity of each authorized intercept target is known only to the requesting LEA. In one embodiment, a trusted entity, such as a network operations facility (NOF , FIG. ), creates a list of ID's corresponding to all SUs within each LEA's jurisdiction. Each SU ID is provided both unencrypted and encrypted for one or more network nodes (NN -R, FIG. ). A network intercept facility (IF , FIG. ) selects a target SU ID, generates an intercept order encrypted for one or more NNs, and sends it to one or more NNs for execution.
