Abstract: A determination is made whether a service provider (28, 40) is capable of supporting at least one service for one of a plurality of subscriber units (30–36, 42–46). The determination is based on whether the service provider has sufficient processing capabilities and memory to receive the service processing software from the subscriber unit and/or whether the service provider is authorized, based on communication system policies to process the particular service request for this subscriber. If the service provider is capable, the subscriber unit provides service processing logic (e.g., the service processing application and/or user customization software) to the service provider. Upon receiving the service processing logic, the service provider stores it and eventually executes it to process the requested service for the subscriber units.

Abstract: A source communication unit (101) transmits a voice message to a target communication unit (103) via a first wireless communication resource. In a first embodiment, the target communication unit transmits a caller data request regarding the source communication unit to a central controller (106) via a second wireless communication resource. The central controller determines and interleaves the caller data, via a third wireless communication resource, with the voice message or with a subsequent voice message. In a second embodiment, the caller data request is sent directly to the source communication unit. The source communication unit includes the caller data with a subsequent voice message transmission to the target communication unit.

Abstract: An analog-to-digital (A/D) circuit comprising a multi-pole gain stage, a quantizer, and a feedback stage is stabilized when an analog input signal is excessive in the following manner. A stabilization detector continually samples a representation of stabilization of the A/D circuit. When the representation of stabilization is unfavorable, the stabilization detector increases, via a stabilizer, phase margin by adjusting the pole locations of the multi-pole gain stage based on the degree of unfavorability of the representation of stabilization. With the increased phase margin, the A/D circuit continues to provide digital representations of the analog input signal.
