Assistant wireless UE positioning method and device

A User Equipment (UE) positioning assistant device, comprising:

• a request sending component configured to, when first UE to which the request sending component belongs does not have a positioning capability, initiate an assistant positioning request to at least one piece of second UE which has finished positioning near the first UE, and store sending time of the assistant positioning request;
• a response receiving component configured to receive assistant positioning information, sent by the second UE, in response to the assistant positioning request, and store receiving time of the assistant positioning information;
• and
• a positioning calculation component configured to determine a spatial position by virtue of the assistant positioning information, the receiving time of the assistant positioning information and the sending time of the assistant positioning request;
• wherein the device further comprises a capability determination component configured to compare an amount of known positioning information of the first UE with a first preset threshold, determine that the first UE does not have the positioning capability based on that the amount is smaller than the first preset threshold, determine that the first UE has the positioning capability based on that the amount is not smaller than the first preset threshold, wherein a source of the known positioning information comprises a satellite and/or a wireless base station and/or a Wireless Fidelity (WIFI) node.

A wireless User Equipment (UE) positioning assistant device, comprising:

• a request receiving component configured to receive an assistant positioning request from first UE without a positioning capability, the first UE configured to store a sending time of the assistant positioning request;
• a comparison component configured to compare signal strength of the assistant positioning request with a second preset threshold of second UE to which the comparison component belongs;
• and
• a response sending component configured to, when the signal strength is higher than the second preset threshold, send assistant positioning information in response to the assistant positioning request to the first UE for the first UE to implement the requested assistant positioning, the first UE configured to store a receiving time of the assistant positioning information;
• wherein the device further comprises a capability determination component configured to compare an amount of known positioning information of the first UE with a first preset threshold,
• wherein the first UE without the positioning capability is a UE of which the amount of known positioning information is smaller than the first preset threshold, wherein the first UE has the positioning capability based on that the amount is not smaller than the first preset threshold, wherein a source of the known positioning information comprises a satellite and/or a wireless base station and/or a Wireless Fidelity (WIFI) node.
