ABSTRACT:
A telecommunications system and method is disclosed which avoids unwanted feature interactions while positioning a mobile station that was in idle mode when the positioning request was received by the network. When the serving MSC/VLR receives a request to collect positioning measurements for a mobile station that is in idle mode, the serving MSC/VLR will set an indicator associated with the subscriber to "busy for connection management due to positioning". This flag will allow the MSC/VLR to make a distinction between a positioning connection and the normal mark of "busy for connection management". Thereafter, when a mobile terminating call arrives to the MSC/VLR for a subscriber that is marked as "busy for connection management due to positioning", the MSC/VLR can place the incoming call in a queue until the positioning measurements are taken and the subscriber being positioned is put back in idle mode.
