    摘要: An apparatus for and method of testing the components of a communication system that uses an ARQ protocol is provided. A processor (117) within the communication system is designated to emulate the ARQ protocol so that the normal paths of communication through the system are tested by creating a path (405) that isolates components (103 and 105) from the remainder of the system and tests the remaining components (107 and 109) using the ARQ-emulating processor (117). The processor (117) is also used to emulate a second protocol.

    摘要: Communication systems having single switching center configurations (100) or multiple switching center configurations (200) detect the occurrence of a mobile-to-mobile call using control messages. When it is determined that the call is mobile-to-mobile, a switching center (101) in the single switching center configuration instructs transcoders (121-123) to operate in a transparent mode. Likewise, when it is determined that the call is mobile-to-mobile, multiple switching centers (201-203) the multiple switching center configuration instruct transcoders (221-223) to operate in the transparent mode. While operating in the transparent mode, the transcoders do not convert compressed digital voice (402) to non-compressed digital voice (401) and vice versa, but do allow the compressed digital voice to pass through as bit-stuffed compressed digital voice (403) and vice versa.

    摘要: Information regarding the present location of a dual-mode (or multi-mode) mobile station with respect to a plurality of communication systems is timely maintained by facilitating automated contact information modifications via, for example, a mobility management server (30). In a preferred approach, upon receiving a message (11) evidencing the supported presence of a mobile station in a first communication system comprising a wireless wide area network, one automatically responds (12) by modifying such contact information as is retained in a Session Initiation Protocol registrar. Testing (21) can be utilized to assure the propriety of making such alterations and/or deletions.
