Abstract
A method in one example comprises the steps of receiving a call intended for a designated cellular subscriber unit at a serving MSC, determining that the designated cellular subscriber unit, during a recent prior use of the serving MSC, responded to an Intersystem Page (ISPAGE) message from a border MSC, and transmitting an initial paging message to the designated cellular subscriber unit via an ISPAGE message directed toward said border MSC.
Claims23
A method comprising the steps of:
- a) receiving a call intended for a designated cellular subscriber unit at a serving MSC having a plurality of border MSCs;
- (b) accessing records of responses to previous Intersystem Pages at the serving MSC that reflect prior uses of the sewing MSC;
- (c) determining from the records that the designated cellular subscriber unit, during a recent prior use of the serving MSC, responded to an Intersystem Page (ISPAGE) message from one of the plurality of border MSC identified from the records;
- (d) transmitting, on a first page attempt to the designated cellular subscriber unit via, the Serving MSC, an ISPAGE message directed toward said identified border MSC;
- wherein the step (c) of determining from the records that the designated cellular subscriber unit, during a recent prior use of the serving MSC, responded to an Intersystem Page (ISPAGE) message further comprises the step of accessing a database that identifies cellular subscriber units that responded to an ISPAGE message from a border MSC.
