Problems solved by technology

The UE sends the uplink signal through the newly-built dedicated channel, and the base station measures the angle of arrival of the uplink signal, which wastes network resources, and when the network resources are not enough to create a new dedicated channel, the angle of arrival of the uplink signal cannot be obtained, and thus cannot Get the location of the UE
At the same time, in the prior art, when the UE is in a non-dedicated channel state, it takes a long time to obtain the angle of arrival, and the acquisition process is also relatively complicated.

Embodiment 1

[0057] FIG. 5 is a flowchart of a method for acquiring location information of a user equipment in Embodiment 1 of the present invention. As shown in Figure 5, taking the UE in an idle state as an example, the method for obtaining the location information of the user equipment in the present invention includes the following steps:

[0058] Step 501, when the location server needs to obtain the location of the UE, it sends a request to the RNC.

[0059] In step 502, the decision system of the RNC determines that there is no RRC connection between the UE and the base station, and initiates the paging of the UE by the base station, and the base station pages the UE through a paging channel.

[0060] Step 503, the paged UE is in an idle state, and sends an RRC connection establishment request message to the base station through RACH after receiving the paging.

[0061] Step 504, after the base station receives the RRC connection establishment request from the UE through the RACH,...

Embodiment 2

[0066] FIG. 6 is a flowchart of a method for acquiring location information of a user equipment in Embodiment 2 of the present invention. As shown in Figure 6, taking the UE in the CELL_PCH state or URA_PCH state as an example, the method for obtaining the location information of the user equipment in the present invention includes the following steps:

[0067] Steps 601 to 602, when the location server needs to obtain the location of the UE, it sends a request to the RNC, and the judgment system of the RNC judges that there is no RRC connection between the UE and the base station, and then initiates the paging of the UE by the base station, and the base station passes The paging channel pages the UE.

[0068] The above two steps are the same as the operation process of step 501 to step 502 in the first embodiment.

[0069] In step 603, the UE is in the CEL_LPCH state or the URA_PCH state, and after receiving the paging, sends cell update (Cell Update) information to the base...

Embodiment 3

[0076] FIG. 7 is a flowchart of a method for acquiring location information of a user equipment in Embodiment 3 of the present invention. As shown in Figure 7, taking the UE in the CELL_FACH state as an example, the method for obtaining the location information of the user equipment in the present invention includes the following steps:

[0077] Step 701, when the location server needs to obtain the location of the UE, it sends a request to the RNC.

[0078] In step 702, the RNC sends a UE capability request message to the UE, requesting to obtain UE capability information.

[0079] In this step, the RNC requests to obtain the capability information of the UE, and may also request to obtain other information from the UE.

[0080] In step 703, the UE is in the CELL_FACH state, and after receiving the request, sends its capability information to the base station through RACH.

[0081] Step 704: After receiving the capability information from the UE via RACH, the base station m...

Abstract

The present invention discloses a method to obtain user equipment position information, which includes procedures below: A. A network control equipment stimulates a user equipment not in a special channel to send an uplink signaling to a base station; B. The user equipment sends an uplink signaling to the base station. The base station measures an angle of arrival corresponding to the uplink signaling. The technic proposal of the present invention enables the base station to measure the angle of arrival corresponding to the uplink signaling sent by the UE by stimulating the UE not in the special channel to send the uplink signaling, thus obtaining position of the UE not in the special channel through a network. In addition, the technic proposal obtains the position information of UE not in the special channel without creating a special channel to save network resource. The method of obtaining UE position information needs a short execution period and simple flows.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for acquiring location information of user equipment. Background technique [0002] With the rapid development of wireless mobile communication technology, smart antennas are more and more widely used in mobile communication systems because they can fully and efficiently use mobile user signals and delete or suppress interference signals based on digital signal processing technology. [0003] In an existing mobile communication system using a smart antenna, the base station can measure the angle of arrival of the uplink signal sent by the user equipment (UE) with a dedicated channel between the radio access network (RAN), that is, the angle of arrival, and Report to the network control device. When a dedicated channel exists between the UE and the RAN, the UE is in a dedicated channel state, such as a cellular-dedicated channel (CELL_DCH) state. The network control de...
