Embodiment 1

[0045] An embodiment of the present invention provides a method for increasing the positioning speed of a terminal in a wireless network, such as Figure 5 shown, including the following steps:

[0046] Step S501, the terminal obtains the activation status of the GPS module of the global positioning system;

[0047] Step S502, the terminal sends the activation status of the GPS module to the wireless access network side, so that the wireless access network side can determine the positioning mode of the terminal according to the activation status of the GPS module.

[0048] Preferably, in this embodiment, when the terminal itself supports the AGPS positioning capability, it obtains the activation status of the GPS module, and adds the activation status of the GPS module to the reported positioning capability information, and reports it together with the positioning capability information to the wireless access network side.

[0049] In one embodiment of the present invention,...

Embodiment 2

[0055] An embodiment of the present invention provides a method for increasing the positioning speed of a terminal in a wireless network, such as Figure 6 shown, including:

[0056] Step S601, the wireless access network side receives the activation status of the GPS module sent by the terminal;

[0057] Specifically, in this step, the wireless access network side receives the positioning capability information reported by the terminal, and obtains the enabling status of the terminal's GPS module from the positioning capability information.

[0058] Step S602, according to the activation status of the GPS module of the terminal, decide the positioning mode of the terminal.

[0059] This step specifically includes: when the wireless access network side supports the AGPS positioning capability of the terminal, if the GPS module of the terminal is turned on, it is determined that the terminal uses the AGPS positioning method to perform positioning measurement; if the GPS module...

Embodiment 3

[0062] An embodiment of the present invention provides a method for increasing the positioning speed of a terminal in a wireless network, which discloses more technical details to describe the methods described in Embodiments 1 and 2 in more detail.

[0063] In this embodiment, in order to send the activation status of the GPS module of the terminal to the wireless access network side, it is necessary to modify the value of the existing AGPS positioning capability information element.

[0064] As shown in Table 1, it is the value definition of the AGPS capability IE (information element) in the UE positioning capability (UE positioning capability) in the current 3GPP 25.331.

[0065] Table I

[0066]

[0067] It can be seen from Table 1 that the current definition only reflects the terminal's support for the AGPS positioning method, but does not reflect whether the terminal has turned on the GPS module. The RAN side can only blindly try the AGPS positioning method for termi...

Abstract

The invention discloses a method and apparatus for increasing terminal positioning speed in a wireless network. The method includes the steps of a terminal obtaining starting situation of a global positioning system (GPS) module, and sending the starting situation of the GPS module to a wireless access network side so as to allow the wireless access network side to determine the positioning mode of the terminal according to the starting situation of the GPS module. Whether the terminal turns off the GPS module can be timely notified to RAN side, so that the RAN side determines the positioning mode of the terminal according to the received notification messages, thereby preventing unnecessary position mode falling flow due to the fact that the AGPS positioning mode is sent to the terminals when the GPS modules is turned off by the terminal sides. In this way, the positioning speed can be increased greatly.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a device for increasing the positioning speed of a terminal in a wireless network. Background technique [0002] At present, in the third generation mobile communication system, the positioning method commonly used by terminals with the highest positioning accuracy is AGPS (Assisted Global Positioning System, Assisted Global Positioning System) positioning. This positioning method uses the GPS module of the terminal, combined with auxiliary information provided by the RAN (Radio Access Network, wireless access network) side, to accurately measure the longitude, latitude, and altitude of the terminal's location and report it to the RAN side. [0003] Whether the RAN side can order the terminal to adopt the AGPS positioning method depends on whether the terminal reports the ability to support AGPS positioning. 3GPP25.331 8.1.3.6 stipulates that the terminal passes ...
