Abstract
A telecommunications system and method is disclosed for creating “virtual Citizen's Band (CB) radio channel groups” within a cellular network. In a first embodiment, the virtual channel groups are built within the Mobile Switching Center (MSC). Each mobile subscriber participant is associated with the other mobile subscriber participants in the MSC, using a transaction identifier and conference bridges. Each group can be monitored, and each individual participants communication link can be controlled independently to facilitate individual disconnection. In a second embodiment, the virtual channel groups are built directly over the air. Participating mobile subscribers within range of each other can communicate directly with one another, using the same forward and reverse traffic channels.
