Abstract: A method (400) and a communication network (210) for cross coding between encoded protocols in a communication system (100) are described herein. The communication system (100) provides communication services to a plurality of endpoints. In particular, the communication network (210) provides a cross coding element (330) coupled to receive a first encoded signal from a first endpoints (230) using a first encoded protocol. The communication network (210) converts the first encoded signal within the cross coding element (330) from the first encoded protocol to a second encoded protocol to produce a second encoded signal. The communication network (210) communicates the second encoded signal to a second endpoint (250) using the second encoded protocol.

Abstract: A wireless communication system (200, 300, 400, 500) mitigates the effects o f excess timing delay caused by varying lengths of communication paths. In one general implementation, a transition communication path (206, 323, 329) is used to transfer a time-advanced version of a timing reference signal so tha t the cumulative time delay at a transition cell (209, 325, 331) is reduced. I n another general implementation, the timing reference signal is time-advanced in all communication paths (403-411), and selected communication paths (403- 407) include a time delay means (423-427, 503-507) such that the cumulative time delay at an area (421) near a target coverage area (130) is reduced. By reducing the cumulative time delay at the area (421) near the target coverag e area (130), a hand-off of a communication of a mobile station (128) into the target coverage area (130) can be performed.

Abstract: In a TDMA cellular network, there is provided a mechanism for shared-carrier frequency-hopping. It comprises: allocating on a frame basis within a reuse diameter to one coverage area during certain timeslot(s) at least one from a pool of TDM-frame-hopped carriers and allocating on a frame basis within that carrier reuse diameter to another coverage area during certain other, substantially non-overlapping timeslot(s) that frame-hopped carrier, all in substantially non-interfering time-synchronism with any proximal reuse of that carrier, whereby the advantages of frequency hopping are obtained. Stated differently, it comprises: at one instant in time, allocating within a reuse diameter to one coverage area at least one of a plurality of hopped carriers and at that same instant in time, allocating within that carrier reuse diameter to another coverage area another of that plurality of hopped carriers, all in time-synchronism with any proximal reuse of that carrier. The control and access carriers may also be included in the hopping pool, causing certain timeslots to be hopped on a sequence different from the others. The pool of hopped carriers is further apportioned among co-located sites into hopping groups, thereby reducing intra-system synchronization requirements. To solve the near/far problem, TDM timeslots bordering hopping boundaries are preferentially allocated to less distant mobile users.

Abstract: A communication system employs a method for exchanging communicated signals between a remote base site (e.g., 63) and a central site (205) on a communication resource (e.g., 77) assigned to the remote base site (63). The central site (205) or the remote base site (63) determines that a signal must be exchanged between the remote base site (63) and the central site (205). The remote base site (63) then allocates the communication resource (77) for exchanging the signal from those communication resources (e.g., 76 and 77) assigned to the remote base site (63) for exchanging signals with communication units (e.g., 18) in the service coverage area (53) of the remote base site (63).

Abstract: A base-site (304) combines baseband frequency hopping and fast-synthesizer hopping to produce an economical frequency hopping communication system (300). The base-site (304) combines the fast-synthesizer frequency hopping capability of transmitters (307-309) with baseband frequency hopping to produce a frequency hopping communication system (300) which serves the same number of subscribers served by transmitters (208-213) in a purely baseband hopping communication system (200), but with fewer transmitters (307-309). The implementation of frequency-selective cavities (312-317) having very low loss eliminates the need for wideband hybrid combiners (112-114), which in turn eliminates transmitted-signal power loss experienced in a purely fast-synthesizer frequency hopping communication system (100).
