The invention concerns a method () and communications unit () for selective receipt of group calls. The method can include the steps of&#x2014;at a communications unit&#x2014;receiving () a request to participate in a group call having at least one identification and having a plurality of participating members, comparing () the identification associated with the group call with a set of predefined blocking configurations and selectively blocking () the request to participate in the group call based on the comparison of the identification associated with the group call with the set of predefined blocking configurations.

Method and communications unit for selective receipt of group calls

A system and method of retrieving dispatch call information from a dedicated database by using interconnect call information. Interconnect call information from an interconnect communication system is obtained. The information identifies a target dispatch subscriber unit in a dispatch communication system. A request is received from a source dispatch subscriber unit. The request includes the interconnect call information. The interconnect call information identifying the target dispatch subscriber unit is extracted from the request. The interconnect call information of the target dispatch subscriber is related to unique dispatch call connection information of the target dispatch subscriber in a dedicated database. The unique dispatch call connection information concerning the target dispatch subscriber unit from the dedicated database in the dispatch communication system is retrieved using the extracted interconnect call information from the request.

System and method for establishing communication services between different users

A mobile communication device () in a communication system () initiates a call over the fixed equipment network of the communication system to another mobile communication device (). If the two mobile communication devices are within sufficient proximity to each other, they may switch to a direct mode of communication. (). The direct mode and network mode of communication are in different frequency bands using different air interface protocols.
