1. A method for connecting a mobile device to a node in a wireless network, comprising the steps of:
- (a) receiving a query for a mobile device from a location based application;
(b) transmitting a first message to the mobile device from an initiating secure user plane location (“
SUPL”
) location platform (“
SLP”
) of a plurality of SLPs in response to the query, the first message being populated with at least one predetermined parameter that identifies the initiating SLP, wherein the first message with the at least one parameter that identifies the initiating SLP is received at the mobile device;
(c) establishing a transport layer security (“
TLS”
) connection to a given node; and
(d) forwarding a second message from the mobile device to the initiating SLP via the given node by associating the parameter with the initiating SLP,wherein the step of forwarding further comprises;
(i) terminating the established TLS connection from the mobile device;
(ii) examining, in response to the terminating, the content of the second message as a function of the message header; and
(iii) selecting, in response to the examining, between (1) establishing a connection between the mobile device and any one of the plurality of SLPs in the network as a function of the availability of each of the plurality of SLPs in the network and (2) establishing a connection between the mobile device and the initiating SLP, wherein the selecting is based on an absence or presence of the at least one parameter in the message header.

Abstract
A system and method for connecting a mobile device to a node in a wireless network. A query may be received for a mobile device from a location based application. In response to the query a first message may be transmitted to the mobile device from a first node, the first message being populated with at least one predetermined parameter. At a second node, it may then be determined whether to forward a second message from the mobile device to the first node via the second node as a function of the availability of the first node or the at least one predetermined parameter.

10. A method for connecting a mobile device to a node in a wireless network, comprising the steps of:
-
(a) receiving a query for a mobile device from a location based application; (b) transmitting a first message to the mobile device from a specific secure user plane location (“
SUPL”
) location platform (“
SLP”
) of a plurality of SLPs in response to the query, the first message being populated with at least one predetermined parameter that identifies the specific SLP, wherein the first message with the at least one parameter that identifies the specific SLP is received at the mobile device;(c) establishing a transport layer security (“
TLS”
) connection to a given node; and(d) determining at the given node whether to forward a second message from the mobile device to the specific SLP via the given node as a function of the availability of the specific SLP or the at least one predetermined parameter, wherein the step of determining further comprises; (i) terminating the established TLS connection from the mobile device; (ii) examining, in response to the terminating, the content of the second message as a function of the message header; and (iii) selecting, in response to the examining, between (1) establishing a connection between the mobile device and any one of the plurality of SLPs in the network as a function of the availability of each of the plurality of SLPs in the network and (2) establishing a connection between the mobile device and the specific SLP, wherein the selecting is based on an absence or presence of the at least one parameter in the message header. - View Dependent Claims (11, 12, 13, 14, 15, 16)
