Description

How to pass location information {METHOD FOR DELIVERING LOCATION INFORMATION}

The present invention relates to a location information service, and more particularly to a location service based on Secure User Plane Location (SUPL).

In recent years, a service for providing a location of a mobile communication terminal has been provided.

In order to achieve such a service, a method of measuring and calculating the location of a mobile communication terminal is utilized. As such a method for measuring and calculating the position of the mobile communication terminal, triangulation after measuring the cell-ID method of transmitting the ID of the cell to which the mobile communication terminal belongs, and the time when the radio wave arrives from the mobile communication terminal to each adjacent base station. There is a method for calculating the position of the terminal using, a method using a GPS (Global Positioning System) or Galileo satellite.

In order to calculate the location of the terminal as described above, the mobile communication network is provided with a relevant function for calculating the location, and provides a location service (Location Service) that delivers the location of the terminal to a certain entity periodically or on request do.

As described above, in order to calculate the location of the mobile communication terminal, a lot of signals and location information must be transmitted between the mobile communication terminal and the location server.

Therefore, recently, standardized location technologies (Positioning Technologies) for providing the location service, that is, location service based on the location of the mobile terminal, are rapidly spreading.

The above-described techniques may be generally provided through a user plane for transmitting user data and a control plane for transmitting control data. As an example of the above technology, location service may be provided through a user plane. There is SUPL (Secure User Plane Location, SUPL) which provides.

The SUPL-based network includes a SUPL agent, a SLP (SUPL Location Platform), a SET (SUPL Enabled Terminal), and the like.

The SUPL agent is a logical service access point for requesting location information of a target SET from the SLP and receiving measured location information of the target SET from the SLP. The SLP is an entity that accesses network resources and performs roaming and resource management in order to obtain location information of the target SET according to a request from the SUPL agent. The SET performs definition procedures with the SLP in SUPL via a user plane bearer.

On the other hand, as mentioned above, the method for measuring the location of the mobile communication terminal to provide the location of the mobile communication terminal has various problems when the mobile communication terminal is indoors or underground. That is, since radio waves of a base station, a GPS satellite, and a Galileo satellite do not reach indoors or underground, there is a problem in that location measurement is difficult. In addition, the cell-ID method has a problem that it is difficult to provide an accurate position because the radius of the cell reaches 3km.

In order to solve such a problem, in recent years, the use of, for example, RFID, two-dimensional bar code, etc. has been focused.

Referring to the scheme using RFID or two-dimensional bar code, the mobile communication terminal collects RFID or two-dimensional bar code information, and transfers the collected information to the server, the server searches and stores the DB with the received information The terminal transmits the corresponding position value corresponding to the received information and the received information to the terminal.

As described above, in order to use a contact or contactless sensor, for example, RFID or two-dimensional bar code for location service, a dedicated protocol for transferring RFID information or two-dimensional bar code is required between the mobile communication terminal and the server.

However, since RFID and two-dimensional barcodes are different in technology, they cannot be integrated into one protocol, and each requires a separate protocol. In addition, since RFID and two-dimensional barcodes have been improved in technology, there is a problem in that protocol development is not easy.

In addition, if similar technologies are developed in addition to RFID or two-dimensional barcodes in the future, protocols must also be newly developed.

However, if a plurality of protocols exist in this way, a service provider that provides location services must continuously improve the system, and there is a problem in that the operating cost is greatly increased.

Accordingly, an object of the present invention is to enable the transfer of RFID, two-dimensional barcodes, and newly developed technologies using a single protocol.

Specifically, the present invention aims to integrate all of the RFID, the two-dimensional barcode, and the newly developed technologies into the Secure User Plane Location (SUPL) protocol.

In order to achieve the above object, the present application provides a method of receiving location information from a mobile terminal having a contact or non-contact sensor and supporting a Secure User Plane Location (SUPL) protocol. The method of receiving location information includes establishing a data connection with a server; Sending a SUPL based start message to the server, wherein a first parameter indicating a type of the contacted or contactless sensor in the SUPL start message or another message, and a second indicating information of the contacted or contactless sensor Parameters are sent and included; And receiving, from the server, a SUPL based termination message including location information based on the information of the sensor.

On the other hand, in order to achieve the above object, the present application provides a method for delivering location information in a server supporting the Secure User Plane Location (SUPL) protocol.

The method may further include receiving a SUPL based start message from a terminal, wherein the first parameter indicates a type of the contact or contactless sensor in the SUPL start message or another message, and the contact or contactless sensor. A second parameter representing information is included; Determining a location of the terminal based on the information of the sensor; The method may include transmitting a SUPL-based end message including location information of the terminal to the terminal.

The present invention makes it possible to transmit information of a contact or contactless sensor, such as information by RFID or two-dimensional bar code, and information by newly developed technology using a single protocol.

Specifically, the present invention enables the delivery of all the information of the contact or contactless sensor, such as RFID or two-dimensional bar code, and information by a newly developed technology, in a Secure User Plane Location (SUPL) protocol.
