Entanglement　swapping　is　a　crucial　step　in　quantum　communication,　generating　long-distance　entanglements　between　quantum　users　for　quantum　network　applications,　such　as　distributed　quantum　computing.　This　study　focuses　on　the　efficiency　of　entanglement　swapping　strategies　in　quantum　networks,　particularly　in　multi-user　concurrent　quantum　communication.　Since　multi-user　concurrent　quantum　communication　consists　of　multiple　point-to-point　quantum　communications,　we　first　analyze　the　challenges　faced　by　existing　entanglement　swapping　strategies　in　this　scenario　and　then　propose　Parallel　Segment　Entanglement　Swapping　(PSES)　to　address　them.　PSES　utilizes　a　tree-like　model　to　divide　the　path　into　segments　and　execute　entanglement　swapping　in　parallel　across　them,　thereby　enhancing　the　generation　rate　of　long-distance　entanglement.　Furthermore,　we　analyze　the　impact　of　resource　contention　on　entanglement　swapping　in　multi-user　concurrent　quantum　communication　and　propose　Multi-user　PSES　(M-PSES)　to　alleviate　this　negative　impact.　M-PSES　leverages　the　entanglement　swapping　trigger　signal　and　resource　locking　mechanisms　to　mitigate　resource　contention.　The　simulation　results　show　that　PSES　performs　superiorly　to　existing　entanglement　swapping　strategies　in　point-to-point　quantum　communication,　and　M-PSES　can　achieve　better　performance　than　PSES　in　multi-user　concurrent　quantum　communication.
