Description

Position prediction method, device and storage medium Technical Field The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for predicting a location, and a storage medium. Background Currently, in the current positioning technology of the third generation partnership project (3rd Generation Partnership Project,3GPP), a terminal device (UE) itself or a third party application (AF/LCS CLIENT) is required to initiate a positioning request for the UE, the former is called MO-LR (Mobile Originated-Location Report), and the latter is called MT-LR (Mobile Terminated-Location Report). Whether MO-LR or MT-LR, the current position information of the UE can be obtained only by calculating the current position of the UE, and the future position of the UE can not be predicted. Disclosure of Invention The invention provides a position prediction method, a position prediction device and a storage medium, which are used for determining predicted position information of a terminal. In a first aspect, a method for predicting a location is provided, the method comprising: The network data analysis function network element NWDAF obtains the current position information of the terminal determined by the location management function network element LMF, NWDAF determines the predicted position information of the terminal according to the current position information of the terminal and the pre-stored historical position information of the terminal. The technical scheme of the invention has the advantages that as NWDAF stores the historical position information of the terminal in advance and NWDAF can acquire the current position information of the terminal determined by the location management function network element LMF, NWDAF can predict the position of the terminal to obtain the predicted position information of the terminal. In one possible implementation, NWDAF receives a first request message from the AMF or LMF, the first request message requesting NWDAF to determine predicted location information of the terminal, the first request message including current location information of the terminal. Based on this possible implementation, NWDAF is a first request message from the AMF or LMF for the subsequent NWDAF to determine terminal predicted location information based on the current location information of the terminal and the historical location information of the terminal. In another possible implementation, NWDAF receives a first request message from the AMF, the first request message being for requesting NWDAF to determine predicted location information of the terminal, the first request message including address information of the LMF for locating the terminal, NWDAF obtaining current location information of the terminal from the LMF according to the address information of the LMF. Based on the possible implementation manner, NWDAF may directly receive the first request message sent by the AMF, and based on the address information of the LMF in the first request message, find the current location information of the terminal required for the LMF to obtain the predicted location information of the terminal. In another possible implementation, the first request message further includes a location prediction identity and/or location prediction configuration information, the location prediction configuration information including at least one of a prediction time, a prediction accuracy, and a format of the predicted location information. Based on the possible implementation manner, NWDAF may determine, when the first request message is received, whether to need to determine the predicted location information of the terminal according to the location prediction identifier, or may determine, according to the location prediction configuration information in the first request message, a criterion that the predicted location information of the terminal specifically needs to meet. In another possible implementation, NWDAF determines the predicted location information of the terminal based on the location prediction configuration information, the current location information of the terminal, and the pre-stored historical location information of the terminal. Based on the possible implementation manner, NWDAF determines that the predicted position information of the terminal is more accurate and reaches the preset standard according to the current position information of the terminal, the pre-stored historical position information of the terminal and the position prediction configuration information. In another possible implementation, NWDAF sends the predicted location information of the terminal to the access and mobility management network element AMF. Based on this possible implementation, NWDAF sends the predicted location information of the terminal to the AMF, which may then send the predicted location information of the terminal to the terminal. In a second
