Claim 4:
5. The joint optimization method for delay and spectrum occupation in the cloud-edge collaborative network according to claim 4, wherein the node and path selection uniqueness constraint is:

Σe∈E,k∈Kx(u,s)e,k=1,∀(u,s)∈CR,Σe∈E,k∈Kx(u,s)e,k=y(u,s),∀(u,s)∈CR, 

wherein x(u,s)e,k a binary variable, if the user request (u, s) is processed at the MEC server node e and the user request is transmitted through the kth path, a value of the binary variable is 1, or otherwise the value is 0, y(u,s) is a binary variable, and if the user request (u, s) is migrated to the second layer, that is, the MEC server node e in the cloud area for processing, a value of the binary variable is 1, or otherwise the value is 0.
