ABSTRACT:
In connection with instances of inter-exchange hand-off, certain hand-off related parameters assigned to border cells within a first system area are evaluated and considered by the second system area in making the inter-exchange hand-off. To communicate these hand-off related parameters from the first system area to the second system area, a request for the parameters is transmitted from a mobile switching center serving the second system area to a mobile switching center serving the first system area. Responsive thereto, the mobile switching center for the first system area retrieves and delivers the requested parameters for subsequent second system area mobile switching center processing in connection with making the inter-exchange hand-off determination. Alternatively, the mobile switching center serving the first system area acts on its own to retrieve and send certain hand-off related parameters to the mobile switching center serving the second system area for subsequent use in connection with making the inter-exchange hand-off determination.
