Title: Method for processing call using virtual number in all range of exchange number and apparatus thereof
Inventor: LYU CHONG WOON
IPC: H04M3/54
Filed: 2006-11-02
Abstract: A method and an apparatus for processing a call by using a VN(Virtual Number) in all the range of exchange numbers are provided to obtain an effect that although virtual numbers are assigned, whether the numbers are virtual or not cannot be recognized and rather they are felt like actual numbers. When an origination call is received, an originating MSC(Mobile Switching Center)(200) transmits a destination information request signal(Location Request) to an HLR(Home Location Register)(S100). The HLR transmits destination information response signal to the originating MSC(S110). The originating MSC transmits an IAM(Initial Address Message) including a destination number, namely, a VN, to an SSP(Service Switching Point)(S120). The SSP sends a command requesting an actual number(Analyzed Information) to an SCP(Service Control Point)(500) in order to know an RN(Real Number) corresponding to the received VN(S130). The SCP extracts an RN and transmits a response command including the extracted RN to the SSP(S140). The SSP transmits a destination information request signal(Location Request) inquiring about location information of a destination subscriber to the HLR(S150). The HLR transmits destination information response signal including a TLDN(Temporary Local Directory Number) including routing information to the SSP(S160). The SSP performs termination to a destination terminal of a destination subscriber corresponding to the RN via the TLDN(S170).
