A method for avoiding unnecessary signalling in a cellular system (100) is disclosed whereby a "VMSC data generation" or similar field of information can be utilized in an HLR queue. When the HLR (104) is storing Location Erasure data in the queue, the HLR (104) can also store the most current "VMSC data generation" field together with the Location Erasure data in the queue. Prior to sending a Location Erasure message to a VMSC (106) from the HLR's queue, the HLR determines whether the current "VMSC data generation" field is different than the one stored in the queue. If so, the HLR (104) can discard the Location Erasure data in the queue, and thus defer from sending the Location Erasure message to that VMSC (106). Alternatively, when the HLR (104) notes a new "VMSC data generation" field, the HLR scans (104) the complete queue and discards all Location Erasure messages associated with an older "VMSC data generation" field than the current one noted by the HLR (104).
