Problems solved by technology

[0009] The disadvantages of the prior art are: 1. The cellular base station needs to periodically send the geographical coordinate/spatial coordinate information and the pseudo-random code information of the terrestrial radio positioning signal transmitting device or the navigation satellite required by the positioning terminal, such as the existing AGPS positioning system. The required transmission of SIB15 takes up more downlink capacity of cellular base stations; 2. In the same geographical area, like a city, there have been cell

Embodiment 1

[0227] Embodiment 1: This embodiment is the specific implementation of the method for indicating the message sending window of the positioning system.

[0228] The implementation process of this embodiment includes:

[0229] The first wireless communication access point sends positioning system message sending window indication information to its service area on the first carrier that it sends and complies with the first wireless communication mode.

[0230] Here, the indication information includes one or a combination of the following information:

[0231] The start time and / or occupied time information of the positioning system message sending window;

[0232] Occupied frequency point and / or occupied frequency band information of the message sending window of the positioning system.

[0233] Here, the positioning system message is one or a combination of the following information:

[0234] It is used to guide the radio positioning terminal to acquire the radio positionin...

Embodiment 2

[0266] Embodiment 2: This embodiment is a specific realization of the sending mode of the positioning system message. It is used when the terrestrial radio positioning signal transmitter sends the positioning system message of the positioning system.

[0267] Such as figure 1 As shown, the implementation process of this embodiment includes the following steps:

[0268] Step 101 , the first wireless communication access point sends indication information indicating the position of the positioning system message sending window to its service area on the first carrier that it sends and complies with the first wireless communication mode.

[0269] Step 102a, the terrestrial radio positioning signal sending device configures a positioning system message broadcast channel on the first carrier, or the second carrier, or the third carrier, or the fourth carrier included in the positioning system message sending window, and broadcasts the positioning system message sending the positi...

Embodiment 3

[0296] Embodiment 3: This embodiment is the specific realization of the terrestrial radio positioning signal sending device, and its composition and structure are respectively as follows Figure 2a-2c shown.

[0297] Such as Figure 2a Described is the basic structure of the device, including a control and baseband processing unit 301, a first configuration unit 302, and a positioning system message sending unit 303; wherein, the control and baseband processing unit 301 is used to control the broadcast channel of the positioning system message. A positioning system message is sent on the system message sending window, and baseband processing is performed on the positioning system message to be sent before sending. The positioning system message sending unit 303 is configured to send the positioning system message on the positioning system message broadcast channel. The first configuration unit 302 will be summarized in detail later, and will not be repeated here.

Abstract

The invention discloses an indicating method of a positioning system information sending window, a terrestrial radio location signal sending device, a wireless communication access point, a radio location terminal and a wireless communication access point-assisted positioning system. The indicating method comprises the following step: indication information for indicating the position of a positioning system information sending window is sent into a service area from a first carrier sent by a first wireless communication access point complying with a first wireless communication mode. The sending mode of positioning system information is specifically as follows: in a positioning system information sending window carried by a second carrier sent by the first wireless communication access point complying with a first or second wireless communication mode, or in a positioning system information sending window carried by the first carrier sent by a second wireless communication access point complying with the first wireless communication mode, positioning system information is sent to the radio location terminal. According to the invention, base station downlink capacity and spectrum resource occupation can be avoided.

Description

technical field [0001] The present invention relates to the field of radio positioning, and in particular to a method for indicating a message sending window of a positioning system, a terrestrial radio positioning signal sending device, a wireless communication access point, a radio positioning terminal and a positioning system assisted by a wireless communication access point. Background technique [0002] In the 3rd Generation Partnership Project (3GPP, 3rdGeneration Partnership Project) technology, when it comes to the content of the Radio Resource Control (RRC, RadioResourceContro1) protocol, the technical content of GPS-assisted positioning has been formulated in Release8, specifically, the network A system information block (SIB, system information block) that needs to be sent for assisted satellite positioning. SIB15 includes SIB15-1 to SIB15-8; and SIB15bis; SIB15-1bis; SIB15-2bis; SIB15-3bis. The transmission of these information involves the issuance of huge auxil...
