【Abstract】 In this paper,key- processing parts of the signaling in GSM systematic signaling analyzer are dissertated. We focus on deeply analyzing and researching BSSMAP and DTAP, the signaling core of A- interface in GSM sys tem, and present the structure of messages of it. Further more, an access of BSS MAP and DTAP decoding is proposed, and it is testified practical and exact on te st in the GSM system.更多还原
