Claim 6:
7. The joint optimization method for delay and spectrum occupation in the cloud-edge collaborative network according to claim 4, wherein the spectrum resource occupation and uniqueness constraint is:

Σe∈E,f∈F,(u,s)∈CRw(u,s)(k,l)e,f≤|F(k,l)|,∀(k,l)∈L; 

Σf∈Fw(u,s)(k,l)e,f=Σk∈Kx(u,s)e,k×P(u,s),(k,l)e,k×F(u,s),∀(u,s)∈CR,e∈E,(k,l)∈L; 

Σe∈E,(u,s)∈CRw(u,s)(k,l)e,f≤1,∀(k,l)∈L,f∈F, 

wherein |F(k,l)| represents a maximum spectrum slot quantity on the link (k, l), it is assumed that each link is allowed to provide the same maximum spectrum slot quantity, P(u,s),(k,l)e,k represents an optical fiber link (k, l) through which the kth working path of transmitting the user request (u, s) from the node s to the MEC server node e passes, and F(u,s) represents a quantity of spectrum slots required for transmitting the user request (u, s).
