1. 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.

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.

12. 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. 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. - View Dependent Claims (22, 23, 24)

25. 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. - View Dependent Claims (26, 27, 28, 29, 30)
