The present invention encompasses various embodiments that provide convenient message callback for users in multi-service communication systems (e.g.,). One set of embodiments enables users leaving messages to provide the callback number or address. This allows the calling party to indicate what communication service is preferable for callback. Another set of embodiments enables users retrieving messages to select the communication service they prefer for callback. The message server () provides this functionality by determining the callback number or address of the preferred type from the callback information provided by the original calling party. The present invention also provides for automatic callback once the called communication unit () receives the callback number or address.

A communication unit (118) provides service information related to a second communication service to a base site (114) that provides a first communication service to the communication unit (118). The base site (114) receives the service information, stores the service information, and receives a service request for the communication unit (118) to participate in the second communication service. Finally, the base site (114) transmits a control message to the communication unit (118), via a control communication resource, to alert the communication unit (118) as to requested participation in the second communication service.

A method and apparatus for utilizing a distributed location register (20 or 22) within a wireless communication system (10) is accomplished by a distributed location register which receives a request for updating communication parameters of a particular communication entity, which may be a communication device, group of communication devices, or grouping of groups of communication devices, or for retrieval of communication parameters of the particular communication entity. To process the request, the distributed location register (20 or 22) interprets it to identify one of a plurality of communication service registers (28-32, 102-112, or 136-140) which stores the communication entity's communication parameters. Having identified a particular communication service register, the communication service register receives, and subsequently processes, the request to retrieve the communication parameters of interest and/or update the communication parameters of interest.

A calling communication unit (210) transmits a dispatch communication request to a communication infrastructure (202). The dispatch communication request includes at least a dispatch identification of a called communication unit (e.g.,216). In response to the dispatch communication request, the communication infrastructure generates an alert message that includes a dispatch identification of the calling communication unit and determines a telephone number associated with the called communication unit. The communication infrastructure then transmits the generated alert message to the called communication unit based on the telephone number associated with the called communication unit.

A mobility processor (34) provides location update parameters to a subscriber unit (SU1-4). The location update parameters indicate conditions upon which the subscriber unit is to provide its location information to the mobility processor. From the location information, the mobility processor determines whether the subscriber unit has provided the location information in a manner that is consistent with the location update parameters. If the mobility processor determines that the subscriber unit did not provide the location information in a manner that is consistent with the location update parameters, the mobility processor generates a new set of location update parameters which are provided to the subscriber unit.

A calling communication unit (210) transmits a dispatch communication request to a communication infrastructure (202). The dispatch communication request includes at least a dispatch identification of a called communication unit (e.g., 216). In response to the dispatch communication request, the calling communication unit receives from the communication infrastructure a telephone number associated with a voice mail server (222) that provides voice mail service to the called communication unit and an identification of a mailbox at the voice mail server. The calling communication unit then transmits to the voice mail server the identification of the mailbox and a voice communication. Finally, the voice mail server stores the voice communication in the mailbox.

A terminating switching center (101-103) receives an initial address message from an originating switching center (101-103). Responsive to the initial address message, the terminating switching center establishes communications with a wireless unit (118-120). When a called party category corresponding to the wireless unit is compatible with a calling party category included in the initial address message, the terminating switching center instructs at least one terminating transcoder (121-123) to operate in a transparent mode. An answer message including the called party category is sent back to the originating switching center. When the calling and called party categories are compatible, the originating switching center instructs at least one originating transcoder (121-123) to operate in a transparent mode. Additionally, communication path identifiers are included in the messages exchanged. In this manner, double transcoding can be eliminated and resources more efficiently used when executing a mobile-to-mobile call.

A dispatch radio communication system (100) that includes a dispatch processor (101) and a voice mail system (103) employs a method and apparatus for providing voice mail service in the dispatch system. The dispatch processor receives a request to communicate from a first communication unit (109), wherein the request includes a dispatch identification (ID) of a second communication unit (110) that is a target of a communication from the first communication unit. The dispatch processor then determines whether the second communication unit can participate in the communication. When the second communication unit cannot participate, the dispatch processor establishes a communication path (122, 126) between the first communication unit and a third communication unit (111) that is coupled to the voice mail system to allow a user of the first communication unit to provide a voice mail message to the voice mail system for a user of the second communication unit.

An apparatus and associated method employ the concept of a central busy list for coordinating the receipt of incoming calls to a subscriber subscribing to the calling services of separate first and second communication networks. The central busy list apparatus cooperates with the networks to register a current call by a subscriber serviced by the first network, to receive a request for interruption of the call serviced by the first network to allow the subscriber to receive an incoming call to be serviced by the second network, to send a request to disconnect to the first network when a priority of the current call is lower than the priority of the incoming call, and to deny interruption of the current call by the incoming call when the priority of the current call is higher.

Method for prioritizing services provided by different network entities

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.

Testing within communication systems using an arq protocol

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.
