Auditing of wireless network node databases

A method for auditing database files of a Mobile Position Center (MPC) and a Positioning Determining Equipment (PDE) in a wireless emergency services network, wherein the MPC is coupled to the PDE by a communication link which is monitored via a heartbeat signal, wherein the heartbeat signal includes an initial signal from the MPC to the PDE and a corresponding return signal from the PDE to the MPC, wherein information indicative of MPC files is incrementally included with sequential heartbeat signals such that each heartbeat includes information representing a different file, the method comprising:

• concatenating data indicative of a position request corresponding to a MPC file in an initial signal of the heartbeat signal;
• and
• determining whether the return signal received from the PDE indicates an error with the position request;
• and
• generating a report of those MPC files corresponding to position requests having an error indication.

A computer program in a computer-readable medium for comparing database files of a Mobile Position Center (MPC) and a Positioning Determining Equipment (PDE) in a wireless emergency services network, wherein the wireless emergency services network includes a plurality of Mobile Switching Centers (MSC) and a plurality of Cells associated therewith and each database file corresponds to a unique MSC and Cell combination, and wherein the MPC is coupled to the PDE by a communication link which is monitored via a heartbeat signal, the computer program comprising:

• a first code segment for including information indicative of a position request corresponding to a MPC file with the heartbeat signal;
• a second code segment for determining whether the heartbeat signal received from the PDE indicates an error with the position request;
• a third code segment for repeating the first code segment and second code segment for each MPC file, wherein information indicative of MPC files is incrementally included with sequential heartbeat signals such that each heartbeat includes information representing a different file;
• and
• a fourth code segment for generating an error report, wherein the report identifies the MPC file associated with a position request error.

A method for synchronizing database files of a local node with database files of a central node in a network, wherein the local node is coupled to the central node via a communication link, the method comprising:

• initiating a monitoring signal to monitor the communication link between the local node and the central node for reestablishing the communication link therebetween responsive to a determination that the communication link is performing incorrectly, the monitoring signal being a periodic heartbeat signal which includes an initial signal from the central node to the local node and a corresponding return signal from the local node to the central node, wherein information indicative of the central node database files are incrementally included with sequential heartbeat signals such that each heartbeat includes information representing a different file;
• integrating information indicative of the files of the local node database with the monitoring signal;
• determining whether the files integrated with the monitoring signal corresponds with files of the central node database via indications in the monitoring signal;
• and
• generating a report including those central node database files determined not to correspond with a file of the local database.
