The invention discloses a system and a method for improving a called call completing rate based on high and low orbit satellite cooperative paging. The system comprises a voice communication module, a low orbit satellite communication module, a core network GMSC, a core network MSC, a core network SBC, a core network SLR and a core network HLR. The working method comprises the following steps: 1) a telecommunication gateway office sends a message through a core network SBC, and a core network GMSC receives the sent message and sends the message to a core network MSC; 2) analyzing the number at a high-speed buffer SLR at the MSC, and judging whether the service information of the number is signed or not and whether the equipment is accessed to the network or not; (3) if the satellite terminal equipment is registered, the VCM-HOS is automatically called, Paging Command information is sent to the user, the user responds by sending Paging RES information, and the gateway station completes authentication through t
