Abstract
A system and method is disclosed that determines the position of a mobile device using information obtained by employing a first location determination protocol (or modality) to control the efficient or advantageous invocation of a second location determination protocol (or modality). The system utilizes information readily available from the Control plane along with request parameters and device capabilities to determine whether to invoke a CoPL or SUPL session.
Claims30
A method for position determination in a wireless communications network having a dual plane capable Gateway Mobile Location Center (GMLC) and including a user device, comprising steps of:
- (a) receiving a request for location information;
- (b) invoking one of at least a control plane and a user plane based on at least one of the group consisting of requesting application, known user device capabilities and network capabilities.
A method for selectively invoking a position determination session in a wireless communications network including a user device, comprising steps of:
- (a) receiving a request for location information;
- (b) accessing control plane position (CoPL) data;
- (c) extracting network-based measurements from the control plane position data;
- (d) determining a user plane invocation parameter based on network access or device information associated with a user plane;
- and
- (e) invoking a user plane position determination session, based on the user plane invocation parameter and the network-based measurements.
A method for multi-plane position determination in a wireless communications network including a user device, comprising steps of:
- (a) receiving a request for location information;
- (b) accessing control plane position data;
- (c) extracting network-based measurements from the control plane position data;
- (d) accessing user plane position data;
- (e) extracting device-based measurements from the user plane position data;
- (f) returning a multi-plane position measurement based on at least the network-based measurements and the device-based measurements.
A method for selectively invoking a position determination session in a visiting communications network, comprising steps of:
- (a) receiving a request for location information;
- (b) sending a request message to a Home Location Register (HLR);
- (c) receiving information regarding the visiting network;
- and,
- (d) invoking a location determination session based on the information,
- wherein the location determination session is one of a control plane location (CoPL) and a user plane location (UPL) determination session.
