Title:
MOBILE COMMUNICATION SYSTEM AND MOBILE COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP3042521
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To adopt an identification code specific to a mobile terminal for an identification code for a traffic channel of an incoming signal and an outgoing signal sent/received between the mobile terminal and a mobile communication network.
SOLUTION: A mobile terminal 1 has a code generator for predetermined modulation/demodulation and makes a call connection request via an access channel based on notice information from a network side device 2. The call connection request includes a machine number of the mobile terminal 1, and the network side device identifies a code corresponding to the code generator that is provided in advance to the mobile terminal and used for a traffic channel for communication based on the model number. The network side device 2 modulates/demodulates a signal of an incoming/outgoing traffic channel based on the identified code. An identification code generated by a terminal specific code generator A27 is used for the outgoing traffic channel and an identification code generated by a terminal specific code generator B17 is used for the incoming traffic channel.
