Abstract: A network-initiated area event triggered positioning method for a terminal in a session-based position information system is discussed. Network-initiation of area-based positioning of a roaming terminal is discriminated according to a proxy mode and a non-proxy mode, and area-based positioning for the roaming terminal is performed in various manners according to whether an SLP for performing the positioning procedure with respect to the discriminated modes is a V-SLP or an H-SLP.

Abstract: According to an embodiment, a location based notification method in a system including a H-SLP (Home-SUPL Location Platform), and a V-SLP (Visited-SLP) having a V-SLC (Visited-SUPL Location Center) and a V-SPC (Visited-SUPL Positioning Center) for a location service, the method comprising: receiving, by the H-SLP, a request for positioning of a roaming terminal; transmitting, by the H-SLP, a session initialization message including a notification mode parameter to the roaming terminal if one or more of location-based notification and verification are required as a result of checking a privacy of the roaming terminal; transmitting and receiving, by the V-SPC, messages with the roaming terminal for performing a positioning process if a positioning start message is received from the roaming terminal.

Abstract: In a method for providing a location information service based upon a user's location, when a user is currently located within a preferred location or preferred area set by the user to apply privacy with respect to a transmission of location information thereto, a procedure for requesting the user's authorization is performed before transmitting the user's location information, namely, a location server checks a location information request for the user located within the preferred location or preferred area according to a privacy profile within the corresponding location or area and performs a user notification and verification process according to the privacy profile, to thereafter determine whether to forward the location information according to the result of the verification.

Abstract: A terminal and method and system for processing SUPL are discussed. According to one embodiment, the invention provides a method of processing a SUPL request for a terminal that has performed roaming, the method comprising: receiving a SUPL INIT message from a home SLP entity, the SUPL INIT message including an indicator that indicates whether a home SLP entity uses a proxy mode or a non-proxy mode; checking the indicator to determine whether the home SLP operates in the proxy mode or the non-proxy mode; and selectively performing authentication with the home SLP entity based on the checking result indicating whether the home SLP entity operates in the proxy mode or the non-proxy mode.

Abstract: When a SET receives a positioning service from a V-SLP by performing a roaming from a H-SLP to the V-SLP in a SUPL-based positioning system, only a new TLS connection is generated using an abbreviated handshake protocol without generating a new TLS session after the roaming. That is, when opening a TLS session for ensuring security in a SUPL-based positioning method, in particular, when opening a new TLS session between the V-SLP (V-SPC) and the SET after opening the TLS session between the H-SLP and the SET, the key information having used in the previous TLS session is provided to the V-SLP to set a new TLS connection, thereby reducing a load of an entire system.

Abstract: A system and method for performing a notification based upon location in a Secure User Plane Location (SUPL) network which is provided with a SUPL Location Platform (SLP) and a SUPL Enabled Terminal (SET) to thus perform a privacy authentication based upon a location of the SET, wherein when a client requests positioning of the SET, the SLP transmits a notification mode parameter to the SET through a session initial message, whereby it can be predefined whether the notification is performed based upon a location or a user when the SLP (i.e., server system) notifies the SET (or the SET user) of the positioning of the SET requested by the client (i.e., a client system), thus to enable the SET to determine a time point of a notification response.

Abstract: A signal processing apparatus in a multi-input/multi-output (MIMO) communication system includes a transmitting end in which a code rate is differently set and a respectively different modulation method is performed at each antenna in consideration of a channel situation of each transmission antenna, coded bits are separately interleaved, and then collectively interleaved to transmit data, and a receiving end in which received data is collectively deinterleaved and then decoded and deinterleaved separately according to each reception antenna, and a channel situation of each signal received from multiple transmission antennas is estimated and fed back to the transmitting end. A different coding rates and modulation method are used at each transmission antenna and the spatial interleaving is performed to obtain a diversity gain in a space domain, and thus, the communication quality can be enhanced.
