1. combine the CID resource needed for the number of users supported calculates more complicated, even cannot ensure certain consistent with actual demand；
2., when planning uses, it is necessary to avoid the CID that agreement retains, introduce the complexity of networking and realization；
3., when PVC is limited, the number of users of support will be unable to expand；
4. the equipment that receives is according to two tuples (PVCID, CID) localization process example, and algorithm is complicated, and performance reduces；
