Delay tolerant call service request method based on multi-hop aerial base station cooperation

Abstract

A delay tolerant call service request method for multi-hop air base station cooperation, comprising: step 1: a plurality of air base stations determine initial positions; step 2: initiator G 1 to the called party G 2 Initiate a call service request; step 3: the air base station processes the call request within the coverage of a single base station; step 4: the air base station processes the call request within the coverage area of ​​the cross-base station; step 5: the air base station group processes the delay-tolerant call request; step 6 : Air base station deployment location movement decision; Step 7: Air base station activates call service link; Step 8: Air base station adjusts to cover the most ground terminal position; Step 9: Concurrent call service handling during air base station movement. It effectively avoids the defects in the prior art that the air base station cannot achieve full coverage of all ground terminals, which leads to the inability to realize call services between some ground terminals through the air base station node, and reduces the call service success rate between ground terminals.

Description

technical field [0001] The invention relates to the technical field of service request, in particular to a delay-tolerant call service request method for cooperation of multi-hop air base stations. Background technique [0002] Compared with manned aircraft, unmanned aerial vehicles have the advantages of small size, low cost, convenient use, low requirements for combat environment, and strong battlefield survivability. Since unmanned aerial vehicles are of great significance to future air combat, all major military countries in the world are stepping up the development of unmanned aerial vehicles. With the continuous maturity and popularization of current unmanned aerial vehicle technology, the aerial Compared with ground relay nodes (ground base stations), base stations (generally using line-of-sight communication frequency bands, such as 300Mhz to 3000Ghz) have obvious advantages in communication coverage, and at the same time have fast mobility, simple deployment, and st...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a multi-hop air base station cooperative delay-tolerant call service request method, which effectively avoids the inability of the air base station to achieve full coverage of all ground terminals in the prior art, resulting in the inability of some ground terminals to pass through the air. The defect that the base station node realizes the call service and reduces the success rate of the call service between the ground terminals
