摘要:
A system and a method for enabling a Home-SUPL Location Platform (H-SLP) to rapidly identify a currently available positioning method of a target SUPL-Enabled terminal (target SET) are provided. To this end, a message, including positioning capabilities (SET capabilities) which represent whether one or more positioning methods exist, to be transmitted from the target SET to the H-SLP is configured to additionally include information representing whether each positioning method is currently available. Accordingly, even if an electric wave environment of the target SET is changed or a positioning method is changed, the H-SLP can rapidly and efficiently perform a positioning because it always recognizes a currently available positioning method.

A method for providing triggered location information of a target terminal is provided. The method includes transmitting by a previous H-SLP a report message informing that a target terminal is in a roaming state during the triggered location service to an H-SLP of the target terminal or the target terminal. The H-SLP of the target terminal selects a new V-SLP based on a location identifier (LID) received from the target terminal, and the H-SLP provides the V-SLP with an ID of the target terminal, a positioning method of the target terminal (SET CAPABILITY), and the LID as the information on the network in which the target terminal currently exists. The newly selected V-SLP determines the positioning method and protocol used for the positioning with the target terminal by using the SET CAPABILITY, the newly selected V-SLP transmits its own IP address and the newly determined positioning method and protocol (POSMETHOD) to the H-SLP. The H-SLP transmits the IP address of the newly selected H-SLP and the new POSMETHOD to the target terminal, the target terminal transmits a positioning inducing message to the new V-SLP and calculates a location value by using the determined POSMETHOD, in such a manner that the triggered location service is maintained even though the target terminal is in a roaming state during the service by performing the step of selecting the H-SLP for calculating the location value of the target terminal without interruption.

A method and apparatus for calculating a location of a User Equipment (UE) that is roaming, the method including receiving, by a Home Location Platform (HLP), a location request message from the UE for starting a positioning session with the UE, wherein the location request message includes specific identifier information of an area in which the UE is located, and positioning capability information including a positioning scheme supported by the UE, determining that the HLP calculated a position estimate, transmitting a request for an approximate coordinate information to a Visiting Location Platform (VLP), receiving the approximate coordinate information from the VLP, exchanging location information with the UE, and calculating a position of the UE using the exchanged location information. According to such a method, it is possible to efficiently perform the positioning of the UE, regardless of the location of the UE, thereby improving the quality of the positioning service.

A method for providing a location value of a Target (SET) in a location information providing system is provided, wherein an Home Secure User Plane Location (SUPL) Location Platform (H-SLP) also checks a period for a positioning and it transmits a positioning start inducing message to the Target SET if an Secure User Plane Location (SUPL) TRIGGERED START message does not arrive from the Target SET within a specific time interval from a beginning of the corresponding period. Therefore, there is a complementary effect on that the positioning can be performed in the preset period.

A method of providing location information of a target Secure User Plane Location (SUPL) Enabled Terminal (target SET) while protecting privacy of a user of the target SET in a Home-SUPL Location Center (H-SLC) providing the location information of the target SET, and the H-SLC, are provided. The method includes receiving a location request message from a requester, transmitting an SUPL INITiation (SUPL INIT) message by using a first session IDentifier (ID) to the target SET, the first session ID including a real ID of the target SET, transmitting a Positioning DATA (PDATA) message by using a second session ID to the Home-SUPL Positioning Center (H-SPC), the second session ID including a pseudo-ID for secure connection between the H-SLC and the H-SPC, receiving a positioning result of the target SET from the H-SPC, and transmitting the positioning result to the requester.

A method and apparatus are disclosed for providing location information of a User Equipment (UE) in a communication system including the UE, a Secure User Plane Location (SUPL) Location Center (SLC), and a SUPL Positioning Center (SPC). The method includes receiving, by the SLC, a request for the location information of the UE from a requester; notifying, by the SLC, the UE that the location information has been requested; transmitting, by the SLC to the SPC, a pseudo IDentifier (ID) for securing a connection between the SPC and the SLC; receiving, by the SLC from the SPC, the location information of the UE with the pseudo ID, the location information of the UE being calculated by the SPC, based on a positioning measurement measured by the UE; and transmitting, by the SLC, the location information to the requester.

摘要:
A method and an apparatus are provided for configuring a Personal Network (PN). A connection request message is received from a Personal Network Entity (PNE) at the PN gateway. A registration request message for a PN, to which the PNE belongs, is transmitted from the PN gateway to a server located in a Wide Area Network (WAN). An authentication request message including ID information of the PN is received at the PN gateway from the server. The authentication request message is forwarded from the PN gateway to one or more PNEs mapped to the ID information of the PN, with reference to a PN routing table in which information about the one or more PNEs is mapped to the ID information of the PN. The one or more PNEs receive a service from the server through the PN gateway.

A mechanism to enable multiple message threads management in the context of the Converged IP Messaging (CPM) service and in the context of CPM inter-working with SMS is provided. A CPM user can simply start a message-based conversation with another CPM or Short Message Service (SMS) user without explicitly establishing a session beforehand. All messages that belong to a given conversation are displayed in the corresponding conversational view (i.e. window) in the CPM user device, even if the conversation is stopped and restarted at a later time, and even if there are multiple message threads available (currently active or stored) in the CPM device. Message structures and behavior of the CPM system elements to enable the functionalities above as well as a mechanism makes the message threads management possible even between a CPM user and an SMS user are also provided.
