[0015] In the above positioning process, the positioning parameters cannot be changed after the LPP message is sent. However, there are some scenarios, for example: during the positioning process, due to changes in requirements, the QoS required for positioning is increased, and the currently selected positioning method cannot meet the QoS; In addition to reporting the geographic location information of the terminal, due to business needs, it is necessary to increase the reporting of terminal speed information; because the terminal cannot meet the positioning calculation requirements, the positioning result calculation terminal needs to be changed from UE to E-SMLC; the triggering method of positioning reporting may be a single report Change to periodic reporting, or the number of periodic reporting, the reporting interval needs to be changed, etc. In the above scenario, some positioning parameters need to be modified during the positioning service process. However, for the existing positioning service implementation process, once the positioning service is carried out After that, the subsequent positioning process cannot be flexibly controlled and cannot meet the above requirements

Embodiment 1
[0060] In this embodiment, the Qos is modified during the positioning process, the requesting party is the terminal, and the requested party is the E-SMLC, image 3 It is a schematicflow chart of the method for modifying positioning parameters in Embodiment 1 of the present invention, such as image 3 As shown, the method includes:
[0061] Step 301: The terminal initiates a location request, carries location Qos, etc., and sends it to the E-SMLC through an LPP location information request (Location information request) message.
[0062] Step 302: After receiving the location request, the E-SMLC requests the location capability of the terminal through a location capability request (Capability request) message.
[0063] Step 303: The terminal carries the supported positioning capability in the positioning capability indication (Capability indication) message, and feeds it back to the E-SMLC. The E-SMLC selects a positioning method according to the positioning capability suppo...
Embodiment 2
[0074] In this embodiment, the periodic reporting time interval is modified during the positioning process, the requesting party is the terminal, and the requested party is the E-SMLC, Figure 4 It is a schematicflow chart of the method for modifying positioning parameters in Embodiment 2 of the present invention, such as Figure 4 As shown, the method includes:
[0075] Step 401: The terminal initiates a location request, carrying location Qos, report type (periodic report total number / report time interval), etc., and sends it to the E-SMLC through an LPP location information request (Location information request) message. Assume that periodic reporting is used here, and the reporting interval is 2 minutes.
[0076] Step 402: After receiving the location request, the E-SMLC requests the location capability of the terminal through a location capability request (Capability request) message.
[0077] Step 403: The terminal carries the supported positioning capability in a pos...

Abstract
The invention discloses a method for modifying positioning parameters, comprising: in the process of positioning service, if a requester needs to modify positioning parameters, a positioning modification message is sent to the requested party, and the positioning modification message carries the positioning parameters that need to be modified; After receiving the positioning modification message, the requested party initiates a positioning negotiation process or saves the positioning parameters that need to be modified for subsequent positioning processes. The invention also discloses a modification system for positioning parameters correspondingly. The present invention can realize the modification of positioning parameters according to actual needs in the process of positioning service, the terminal and the network can update the relevant positioning parameters in time, and realize the positioning service according to the latest positioning parameters, thereby improving the flexibility of the positioning service.
Description
technical field [0001] The invention relates to positioning technology, in particular to a method and system for modifying positioning parameters. Background technique [0002] At present, mobile communication technology is faced with the problem of providing users with higher data rate, providing better coverage and larger capacity for the network. In order to solve the above problems, the 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP) launched the Long Term Evolution (LTE) project of the wirelessaccess network, the evolved access technology (E-UTRA), and the evolved access network (E-UTRAN), and the All-IP-oriented Packet Domain Core Network Evolution (SAE) project, hope to provide better support for the growing needs of operators and users through continuous evolution and enhancement from the radio interface to the core network. [0003] LTE is a technology centered on Orthogonal Frequency Division Multiplexing (OFDM) and Single Carrier-Fre...
