A system and method of detecting radio network trends in a telecommunications network. A data mining tool ( ) is provided and adapted to search through the various operations and maintenance database systems belonging to one or more communications network(s) ( ). The data mining tool searches through the databases to find correlations and dependencies among the parameters of the data collected and stored in the database systems. The correlations and dependencies found are then reported for further analysis which can, in turn, be used in optimization, maintenance and trouble shooting of the network.

Automated radio network trend detection

A system, method, and apparatus for transmitting and receiving group calls are illustrated. The group call register includes a counter value which identifies particular calls. The counter value is transmitted in the notification message, thereby identifying both the group and the group call. After the subscriber finishes listening to the group call, the subscriber can cause the mobile station to store the group identification number and the counter value in the group call history memory to prevent being alerted of the same group call in the event that the call is repeated. Additionally, the mobile station establishes a point-to-point call to an acknowledgment center and transmits the group identification number as well as the counter value. The group identification number and the counter value are stored in the acknowledgement center, thereby establishing a record of mobile stations that have listened to particular calls.

System, method, and apparatus for distinguishing between different group calls

A system, method, and apparatus for updating Group Call Registers (GCR) is presented, wherein modifications to group call areas are transmitted to neighboring Mobile Switching Center/Visitor Location Register (MSC/VLR) service areas. Information regarding cells which are either added to, removed from a group, or part of a new or terminated group is transmitted to any neighboring MSC/VLR service areas adjacent to the cell. In one embodiment, the information is transmitted over the Signaling System 7 (SS7) Network. In a second embodiment, the information is sent over a network connecting the GCRs.

Support for transfer of neighboring cell information between MSC areas for VGCS/VBS calls

Signaling Connection Control Part (SCCP) parameters within a signal generated within a first SS7 telecommunications network are converted into values and formats acceptable by a second SS7 telecommunications network by a converter residing within a gateway Signal Transfer Point (STP). Such a converter enables signals containing application layer data to be transported across two different SS7 telecommunications networks that are otherwise incompatible.
