Description

A trigger positioning method, a SUPL positioning server, and a SUPL terminal. The application is submitted to the Chinese Patent Office on December 18, 2008, and the application number is 200810240381. 5. The invention name is "a trigger positioning method, a SUPL positioning server, and a SUPL terminal. The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference.

Technical field

The present invention relates to positioning of a mobile communication terminal, and more particularly to a trigger positioning method applied to a secure user plane location SUPL, a SUPL positioning server, and a SUPL terminal.

Background of the invention

In order to support the positioning of the mobile communication terminal, the mobile communication network develops a corresponding positioning protocol for performing positioning related operations between the positioning platform or the positioning server and the mobile communication terminal, such as acquiring the positioning capability of the terminal and transmitting the positioning signal measurement station. Auxiliary data is required and measurement results are requested from the terminal.

In the process of implementing the present invention, the inventors have found that the following problems exist in the prior art:

At present, the positioning operation is generally completed by the control plane, and the control plane positioning protocol includes the RRLP (Radio Resource LCS Protocol) under the GSM network and the UMTS (Universal Mobile Telecom Mu-nications System) network. RRC (Radio Resource Control) and TIA-801 under CDMA network. However, this control plane positioning scheme requires the participation of all entities in the mobile network, which is not conducive to deployment and evolution, because adding a new feature requires the entire network transformation, which is too expensive.

Another positioning scheme is user plane location, using a user plane location service system SUPL (secure user plane location), wherein the SUPL terminal (SET) is interactively completed by the user plane and the SUPL location platform (SPL). Positioning, however, substantial positioning also relies on the control plane positioning protocol because the message of the control plane positioning protocol is to be delivered as a payload of the SUPL message. In addition, the SUPL positioning server SLP includes two parts: a SUPL Location Center and a SUPL Positioning Center. The SUPL positioning center SLC is responsible for coordinating the operation of the SUPL in the network for carrying on the user plane. On the SET interaction, the SUPL Location Center SPC is responsible for all the messages and processes required for location calculation and auxiliary data transmission.

The location services currently provided by SUPL include immediate location and trigger location. The immediate location is to locate the target SET and respond to the location information to the application after the location server SLP receives the location request of other applications. The trigger location is in the location server SLP. After receiving the location request of other applications, the target SET is located under certain conditions. Two types of triggers are currently defined, namely periodic and regional events. Under the periodic type, the SET is positioned once every time interval, and the location information is sent to the location requester. In the area event type, the SET receives the area event triggering parameter delivered by the SLP, including: a target area description, such as a circle, an ellipse, a polygon; a target area related cell ID list, which is generated by the SLP according to the target area description and the cell location information; The event, such as entering, leaving the target area, or in the target area, the event can investigate the distribution of the current tracking SET set; and the minimum time interval and maximum number of event reports, if the event needs to be repeatedly reported, the SET enters the cell list. The cell should be located in the cell to determine whether the specified event has occurred. If it occurs, the event is reported to the network. The current location information can be reported.

However, the current trigger positioning does not support trigger parameter update, such as the positioning interval and the number of positioning times during periodic positioning. In actual applications, it may be necessary to change the positioning interval and the number of positioning times. For example, the current tracking target speed increases, and more frequent Positioning, while the tracking target speed is reduced, it is hoped that the positioning frequency is lowered; and when the regional event is located, the location requester may wish to change the target area. Under the current technology, the current SUPL session is terminated, and a new session is started, which directly leads to service performance. reduce.

Summary of the invention

The main purpose of the embodiment of the present invention is to provide a solution for updating the trigger parameters of the SUPL terminal, so as to solve the problem that the triggering parameter cannot be updated by the current trigger positioning.

The above object of the embodiment of the present invention is achieved by the following technical solutions:

A trigger positioning method is applied to a positioning server, and the method includes: receiving a trigger parameter update request sent by a location requester and a new trigger parameter; and sending a message including the new trigger parameter to the terminal.

A user plane location service system SUPL location server, the SUPL location server includes a SUPL location center and a SUPL location center, and the SUPL location center includes: a trigger parameter update request receiving unit, configured to receive a trigger parameter update sent by the location requestor a request and a new trigger parameter; a trigger parameter sending unit, configured to send a message including the new trigger parameter to the terminal.

The embodiments of the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings. The illustrative embodiments of the present invention and the description thereof are intended to be illustrative of the invention, but are not intended to limit the invention.

Embodiment 1:

The embodiment of the present invention provides a trigger positioning method, which is applied to a positioning server. The present embodiment is described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a trigger positioning method according to the embodiment. Referring to FIG. 1, the trigger positioning method in this embodiment includes the following steps:

101: Receive a trigger parameter update request sent by a location requester and a new trigger parameter;

In this embodiment, the trigger parameter update request sent by the location requester includes new target area information and trigger parameter update indication of the SUPL terminal.

102: Send a message including the new trigger parameter to the SUPL terminal, so that the SUPL terminal performs trigger positioning according to the new trigger parameter.

According to this embodiment, the new trigger parameter can be sent to the SUPL terminal SET by the SUPL positioning center SLC through the TRIGGERED RESPONSE message.

Since the current trigger parameter is sent by the SUPL positioning center SLC to the SUPL terminal SET through the TRIGGERED RESPONSE, and the TRIGGERED RESPONSE message appears only after the SUPL terminal SET sends the TRIGGERED START message, if the SUPL terminal SET can be triggered to re-initiate the TRIGGERED START message, The new trigger parameter can then be returned by the TRIGGERED RESPONSE message returned to the SUPL terminal SET. At the moment triggering the positioning, if the SET switches the V-SLP, the V-SLP1 indicates that the SET has left its own coverage, and the SET will receive the END (status code=no coverage) message, so it is known that it needs to switch to a new V_SLP, so SET resends TRIGGERED START (including the corresponding Cause Code=no coverage indication) to H-SLP, H-SLP selects another V-SLP2 to trigger the positioning session, H-SLP responds to TRIGGERED RESPONSE to SET, including V-SLP2 support The positioning method also re-issued the trigger parameters. For regional event triggering, the H-SLP may update the area ID set of the trigger parameter as needed, but does not update the target area _{0. The} specific implementation manner will be described in detail in the following embodiments.

Therefore, if the positioning session that triggers the positioning is started (this may require the SET and the SLP to establish a data connection), the SET has already performed the V-SLP switching, and the H-SLP can already update the ARE of the area ID set information. That is, a status code value is extended to indicate that the H-SLP needs to update the trigger parameters of the SET.

According to this embodiment, the new triggering parameter may also be extended and carried by the SUPL positioning center SLC through other messages sent to the SUPL terminal SET. For example, when the positioning session is completed, a new trigger is sent by the positioning session completion message REPORT message. Parameters, or delivered via an INIT message. The specific implementation will be described in detail in the following embodiments.

In the method provided by the embodiment, when the SUPL terminal SET initiates a positioning session, the network end indicates, by the END message, that the SUPL terminal SET resends the TRIGGERED START message from the SUPL positioning center. The H-SLC receives new trigger parameters.

According to the embodiment, the END message can be extended by extending the SUPL END message, for example, a new Status Indicator value of the information indicator type is defined in the SUPL END message, and is used to indicate that the SLP wants to update the horn parameter, such as: Code=TriggerParametersUpdate o

According to this embodiment, the above SUPL TRIGGERED START message needs to be extended, for example, a new Cause Code i. TriggerParametersUpdate is defined in the SUPL START Triggered message, which is used to indicate that the SET expects to receive a new trigger parameter, such as Cause Code= TriggerParametersUpdate ₀

The embodiment will be described in detail below with reference to the accompanying drawings.

204: The H-SLP receives the positioning session request of the SUPL terminal SET to end the positioning session message END response, and the end positioning session message END includes a trigger parameter update indication.

205: The SUPL terminal receives the END message that includes the trigger parameter update indication, and sends a TRIGGERED START message containing the corresponding trigger parameter update reason to the H-SLP to confirm that the update request is accepted.

It should be noted that this step is not required.

206: The H-SLP receives the TRIGGERED START message, and responds to the SUPL terminal SET by using a TRIGGERED RESPONSE message, where the TRIGGERED RESPONSE message includes a new trigger parameter.
