PURPOSE:To avoid crosstalk in an area where service areas are overlapped by setting individually a channel allocation sequence in the multi-channel system relay station radio equipment. CONSTITUTION:The allocation sequence of a speech channel of a 1st relay station 7 is set to a 1st channel and the allocation sequence of a speech channel of a 2nd relay station 8 is set to a 3rd channel. The system is provided with mobile stations 9-12, a service area 13 of the 1st relay station 7 and a service area 14 of the 2nd relay station 8. In the case of talking from the mobile station 9 to the mobile station 10 via the 1st relay station 7, the talking state is made through a 1st channel of the 1st relay station 7. In the case of talking with the mobile station 11 resident in an area where the service areas are overlapped from the mobile station 12 via the 2nd relay station 8 during the talking, the 3rd channel of the 2nd relay station is used for the talking. Thus, since the 1st and 3rd channels use different frequencies, although the mobile stations 10, 11 are resident in an area where the service areas are overlapped, crosstalk is avoided. |
