METHOD FOR EXPANDING SCALE OF PERSONAL COMMUNICATION SERVICE SYSTEM USING BRIDGING SHARED LINE STRUCTURING FUNCTION

Japanese Patent JP3474379

B2

PROBLEM TO BE SOLVED: To expand PCS through the use of a line structure connecting system to systems from small to large by using the bridging line structure function of a switch system enabling a PCS system to be added.
SOLUTION: Switch node constitutes each PCS system. The switch system 104 assigns each of radio sets to a telephone number and a bridging line structure group. For example, radio sets 111 to 113 are respectively assigned to groups 101 to 103. Each group is provided with one BRI interface to a switch node. For example, an BRI interface 107 of the group 101 assigned to the radio set 111 is mutually connected with the BRI interface 123 of a switch node 121 by way of a link 109, and an BRI interface 108 is mutually connected with the BRI interface 131 of a switch node 122 by way of a link 110.
