1. A method for determining at a first node a first identifier for a mobile device in a multi-plane wireless communications network, comprising the steps of:
- (a) obtaining at the first node via a first plane of the network a second identifier for the mobile device;
(b) receiving at a second node via a second plane of the network a first signal transmitted from the first node;
(c) determining at the second node the first identifier as a function of the first signal; and
(d) receiving at the first node a second signal transmitted from the second node to thereby determine the first identifier at the first node,wherein the first lane is a control lane and the second plane is a user plane.

Abstract
A system and method is disclosed that correlates the MSISDN of a target mobile by performing an out of band request using a IMSI. The correlation between the MSISDN and the IMSI of IMEI is cashed at a database for retrieval. The correlation of the MSISDN allows the position of a mobile device to be determined using a CoPL and/or SUPL location determination sessions.

11. A method for requesting from a first node the location of a mobile device in a multi-plane wireless communications network, comprising the steps of:
-
(a) obtaining at the first node via a first plane of the network a second identifier for the mobile device; (b) receiving at a second node via a second plane of the network a first signal transmitted from the first node; (c) determining at the second node the first identifier as a function of the first signal; (d) receiving at the first node a second signal transmitted from the second node to thereby determine the first identifier at the first node; and (e) transmitting from the first node a request to locate the mobile device, wherein the first plane is a control plane and the second plane is a user plane. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for resolving subscriber identification information in a multi-plane wireless communications network including a gateway mobile location center (GMLC/SLM), a home location register (HLR), a mobile switching center (MSC), and a SUPL enabled terminal (SET), comprising steps of:
-
(a) initiating a location request through a control plane; (b) transmitting a first identifier from the GMLC/SLM to the HLR; (c) receiving a second identifier at the GMLC/SLM from the HLR, the second identifier corresponding to the first identifier; (d) storing the first and second identifiers and correspondence information there between at the GMLC/SLM; (e) transmitting the second identifier to one of a serving mobile location center and a SUPL positioning center (SMLC/SPC); (f) selecting user plane positioning for the location request; (g) transmitting the second identifier from the SMLC/SPC to the GMLC/SLM; (h) resolving the first identifier corresponding to second identifier; (i) returning to the SMLC/SPC the corresponding second identifier; and (j) invoking SUPL signaling to the SET based on the first identifier and corresponding second identifier. - View Dependent Claims (22, 23, 24, 25, 26, 27)
