Methods and wireless network for including vertical application layer service area in seal server

A vertical application layer (VAL) server in a wireless communication system, the method comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to;
• transmit, to a location management server, a user equipment (UE) information request message including a first VAL service area identity (ID) of a first VAL service area, and
• receive, from the location management server, UE information as a response to the UE information request message,
• wherein the UE information includes a list of at least one UE whose location is within an application defined proximity range of the first VAL service area corresponding to the first VAL service area ID, and
• wherein the application defined proximity range includes a range in which the UE information is required.
