Abstract: This paper proposes a new model of information transmission service adapted to heterogeneous communication network of emergency command system. The main functions of the model and some key technologies such as node labeling, routing table generating & maintaining and so on. This model takes into account the characteristics of heterogeneous communication networks and the development trend, uses IP network as the system’s main communication means, and uses other communication means to meet the special communication needs. Application proves that the model improve the capacity of emergency command system, and reduces the complexity of heterogeneous communication.

Key words: transmission service, heterogeneous communication network, path choosing, User Datagram Protocol(UDP)
