Description

Communication method, device and storage medium Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method, apparatus, and storage medium. Background In related art, in an emergency call service based on a ground base station, after receiving an emergency call of a terminal device, an IMS (IP Multimedia Subsystem ) acquires location information of the terminal device in a TAC (TRACKING AREA Code ) and NCGI (NR Cell Global Identifier, NR cell global identifier) from a PCF (Policy Control Function ) or PCRF (Policy AND CHARGING Rules Function) of a core network through an SBC (Session Border Controller ) or a P-CSCF (Proxy Call Session Control Function, proxy call session control Function) to complete subsequent processing, and if the terminal device information cannot be acquired at a 5GC (5G Core Network) side, the TAC information and NCGI information carried in an SIP message sent by the terminal device are queried. The IMS forwards the emergency call request to a designated emergency call center for processing according to the TAC information and the position information of the terminal equipment in NCGI information. In the satellite communication scenario, the above solution is no longer applicable due to the high speed movement of the satellites. In addition, in the related art, the position of the terminal equipment can be identified by using the wave position number, but in the satellite communication scene, because the single wave position coverage area of the satellite base station can reach thousands of square kilometers at the minimum, the user position obtained by relying on the wave position identification can not meet the requirement of accurately routing the call request to the emergency call center of the provincial area. Disclosure of Invention The present application aims to solve at least one of the technical problems in the related art to some extent. In a first aspect, the application provides a communication method applied to first network side equipment, which comprises the steps of receiving session request information sent by terminal equipment, obtaining target position information of the terminal equipment, matching a target call center based on the target position information, and sending the session request information to the target call center so as to establish communication between the terminal equipment and the target call center. In one implementation, the acquiring the location information of the terminal device includes acquiring first location information carried in the session request information as the target location information. In an alternative implementation, the session request information is SIP INVITE messages, and the obtaining the first location information carried in the session request information as the target location information includes obtaining the first location information carried in a header field of the private access network information of the SIP INVITE messages as the target location information. In one implementation manner, the obtaining the location information of the terminal device includes obtaining second location information from a second network side device as the target location information, where the second location information is reported to the second network side device in advance by the terminal device. In an alternative implementation manner, the second location information is reported to the second network side device by the terminal device through a user location information cell. In a second aspect, the application provides a communication method applied to a second network side device, the method comprises the steps of obtaining second position information reported by a terminal device, and sending the second position information to a first network side device when the terminal device sends session request information to the first network side device and the session request information does not carry first position information, so that the first network side device matches a target call center based on the second position information, and forwards the session request information to the target call center to establish communication between the terminal device and the target call center. In one implementation manner, the obtaining the second location information reported by the terminal device includes obtaining the second location information uploaded by the user information network element when the terminal device registers with the second network side device.
