Embodiment 4

[0061] Embodiment 4 provides another application situation, the SUPL session is initiated / calculated by the terminal, and the SET only supports the RRC positioning protocol, which is used in both GERAN and UTRAN, but the specific system time information obtained by the RAN is different, and the transmission The way to SET is also different. If under UTRAN, use the auxiliary data block transmission of the positioning protocol message, if under GERAN, extend SUPL to transmit, because the system time information formats of different RANs are different. Specific steps are as follows:

[0062] A2. The SLP sends an INIT message to start the SUPL session, and A-GALILEO SET assisted and A-GPS SET based indicate the specific positioning methods supported by the SLP.

[0063] B2. The terminal establishes a data connection with the SLP.

[0064] C2. The SET sends a POS message to start the positioning session. RRC is the positioning protocol supported by the SET. A-GPS SET based indicat...

Embodiment 5

[0071] Embodiment 5 is an SLP-initiated / terminal-assisted SUPL session, using the RRLP positioning protocol, but when the terminal receives the assistance data, it finds that the GERAN cell has been handed over to the UTRAN cell, and the terminal ends the SUPL session with END, indicating that the positioning protocol error Or the system time synchronization error, SLP restarts the SUPL session. The specific implementation steps are as follows:

[0072] A3. The SLP sends an INIT message to start the SUPL session.

[0073] B3. The terminal establishes a data connection with the SLP.

[0074] C3. The terminal sends a POS message to start a positioning session. RRLP is a positioning protocol supported by the terminal. A-GPS SET based indicates the specific positioning method that the SET wants to use. The terminal also makes a corresponding auxiliary data request (encapsulated in the Positioning Payload data block of the POS message, and the Positioning Payload follows the RRLP...

Embodiment 6

[0080] Embodiment 6 is the process of SLP initiating / SET calculation. This embodiment provides an example of how to implement the method in a network that does not support a system time synchronization mechanism (such as WLAN). In this session, when the SET is handed over from the WLAN cell to the UTRAN cell, the system time associated with the UTRAN cell can be requested to improve the positioning process.

[0081] A4. The SLP sends an INIT message to start the SUPL session.

[0082] B4. The SET establishes a data connection with the SLP through the WLAN.

[0083] C4. The SET sends a POS message to start the positioning session. RRC is the positioning protocol supported by the SET. A-GPS SET based indicates the specific positioning method that the SET wants to use. The SET also makes a corresponding assistance data request (but does not include a system time request), and the SET also reports the ID information of the current WLAN cell as rough location information to help ...

Abstract

The invention discloses a security user interface positioning method, a terminal and a server. The method comprises: establishing data connection with a user interface positioning platform SLP and sending a first start positioning conversation message to the SLP, wherein the first start positioning conversation message comprises a first cell mark; receiving the assistant data related to the firstcell sent by the SLP; sending a second cell mark to the SLP; receiving the system time message related to the second cell, monitoring the second cell signal, and finishing synchronization of a local clock and a satellite system time; and finishing satellite positioning measurement according to the assistant data. Correspondingly, the invention also provides the terminal and the server for implementing the method. The embodiment of the invention obtains system time message related to network after switching in time when switching occurs during wireless access to network in the positioning phase, so that the synchronization of system time and smooth complementation of the subsequent positioning measurement operation can be ensured, and positioning performance can be improved.

Description

technical field [0001] The invention relates to the field of mobile communication applications, in particular to a secure user plane positioning method terminal and server. Background technique [0002] In order to support the positioning of mobile terminals, mobile networks are developing corresponding positioning protocols, which are used for positioning-related operations between positioning platforms or positioning servers and terminals, such as obtaining terminal positioning capabilities and sending auxiliary data required for positioning signal measurement and request measurement results from the terminal, these operations are done through the control plane. Control plane positioning protocols such as RRLP (Radio Resource LCS Protocol) under the GSM network, RRC (Radio Resource Control, radio resource control) and CDMA under the UMTS (Universal Mobile Telecommunications System) network TIA-801 under the network. [0003] The control plane positioning solution require...
