Monitoring boundary crossings in a wireless network
First Claim
1. A method of providing location-based services for a mobile unit operating in a wireless network including a processing platform, data storage associated with the processing platform, and a plurality of cell sites;
- the method comprising;
receiving an identifier associated with the mobile unit;
receiving geographic zone boundary information;
storing the geographic zone boundary information in the data storage associated with the processing platform;
identifying a number of cell sites characterized by a cell site coverage area intersected by the geographic zone boundary, wherein each of the identified number of cell sites comprise a plurality of cell sectors having a cell sector coverage area and having a cell sector boundary;
identifying a subset of cell sectors characterized by a cell sector coverage area intersected by the geographic zone boundary;
defining a service zone region formed by the union of the subset of cell sectors;
defining a service zone boundary formed by portions of the boundaries of the identified subset of cell sectors;
monitoring a location of the mobile unit using the identifier and a network-assisted location finding system to identify a crossing of the service zone boundary by the mobile unit; and
transmitting service information to a system user in response to the crossing of the service zone boundary.

Abstract
A method of providing location-based services for a mobile unit operating in a wireless network including network structures. The method includes receiving an identifier associated with the mobile unit. The method also includes monitoring a location of the mobile unit using the identifier and a network-assisted location finding system to identify a crossing of a service zone boundary by the mobile unit. The service zone boundary is defined by reference to at least one of the network structures. The service zone boundary also corresponds to a geographic zone boundary. The method further includes transmitting service information to a system user in response to the crossing of the service zone boundary.

10. A method of identifying service zone boundary crossings by a mobile unit operating in a wireless network including a plurality of cell sites, each of the plurality of cell sites comprising a plurality of cell sectors, the wireless network comprising a network-based location finding system, the method comprising:
-
defining a geographic zone boundary; identifying a number of the plurality of cell sites characterized by a cell site coverage area intersected by the geographic zone boundary; identifying a number of the plurality of cell sectors characterized by a cell sector coverage area intersected by the geographic zone boundary; defining a service zone region formed by the union of the identified number of the plurality of cell sectors; receiving an identifier associated with the mobile unit; receiving a location of the mobile unit from the network-based location finding system; monitoring the location of the mobile unit to identify an entry and/or an exit of the mobile unit into the service zone region; and transmitting service information to a system user in response to the entry and/or exit of the mobile unit into the service zone region. - View Dependent Claims (11, 12, 13, 14)

15. A method for providing services based on a location of a mobile unit in a wireless communications network, the wireless communications network including a network-assisted location-based services application;
- the method comprising;
receiving a geographic zone boundary referenced to a geographic topology; converting the geographic zone boundary to a service zone boundary referenced to a wireless communications network topology, wherein converting the geographic zone boundary to a service zone boundary comprises; identifying cell sites having a coverage area intersecting the geographic zone boundary; identifying cell sectors from the identified cell sites, wherein the identified cell sectors have a coverage area intersecting the geographic zone boundary; forming a union of the identified cell sectors; and defining the service zone boundary formed by portions of boundaries of the union of the identified cell sectors; receiving a mobile unit identifier; monitoring the location of the mobile unit, using the network-assisted location-based services application and the mobile unit identifier, to identify a crossing of the service zone boundary by the mobile unit; and transmitting service information regarding the mobile unit in response to the crossing of the service zone boundary by the mobile unit. - View Dependent Claims (16, 17, 18, 19, 20)
