Patent ID: 7848345

Claim:
A communication network using code division multiplexing technology, comprising: a plurality of communication terminal interfaces, each of which has a first decoding circuit for decoding a received data using a first defusing code that is different for every communication terminal interface, a second decoding circuit for decoding a transmission control signal using a second spreading code that is common to each communication terminal interface, a packet control circuit for deciding whether a decoded signal is a data signal or the transmission control signal, and an encoding circuit for encoding a data signal using said first defusing code and encoding the transmission control signal using said second spreading code, and a communication circuit which connects said communication terminal interfaces to each other, wherein said packet control circuit decides the destination address of the transmission control signal when it has been received by a particular one of said communication terminal interfaces, and generates a response signal indicating permission/refusal of the connection in the case where the destination address is the address of said particular one of the communication terminal interfaces, and wherein said encoding circuit encodes said response signal and transmits it.
