【Abstract】 Relationships between application layer protocols in softswitch are explored. Two concepts, i.e., protocol relationship and protocol grouping, are proposed. On the basis of a well known protocol relationship named protocol conversion, three novel protocol relationships including protocol collaboration relationship, protocol cooperation relationship and protocol independency relationship are presented, so that protocol relationships are classified into four types. According to the functionality and purpose of each protocol, main protocols related to softswitch are divided into five groups. A theorem of protocol relationships in softswitch is induced from all kinds of service scenarios of softswitch. This theorem summarizes protocol relationships within each protocol group or between each two protocol groups. A merit of protocol grouping together with classification of protocol relationship is also presented.更多还原
