Abstract
In a Mobile Services Switching Center/Visitor Location Register (MSC/VLR), requests (made by a mobile station (MS)) for supplementary services may require processing only by the MSC/VLR, or they may require processing by a Home Location Register (HLR). A method of managing supplementary service procedures that are processed by an HLR includes supplying the MSC/VLR with a list containing only those supplementary service operations that shall be terminated in the MSC/VLR. In the MSC/VLR, a forward direction message is received from an MS, the forward direction message including an intended supplementary service operation. Then, the intended supplementary service operation is compared with the list of supplementary service operations. If the intended supplementary service operation is contained in the list of supplementary service operations, then the intended operation is terminated in the MSC/VLR. However, if the intended supplementary service operation is not contained in the list of supplementary service operations, then the forward direction message is forwarded, unaltered, to the HLR.
