Positioning infomration indicating method, signal sending device, access point, terminal and system

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...

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 cellular mobile communication systems of different operators, for example, there is a GSM network in the same city. , UMTS, LTE, TD-SCDMA, CDMA2000, in order to support network-assisted satellite positioning, the systems of these different operators need to send auxiliary information for assisted positioning, which leads to the same auxiliary information in the same geographical area. Repeated transmission in different cellular mobile communication systems occupies too many spectrum resources, resulting in a waste of spectrum resources
