BSC
BSC follows IS-2000 & IS-2001(IOSV4.0) BSC is located between BTS and MSC, between PDSN and BTS. BSC has functions, which are call control and maintenance. BSM is connected to BSC(CAN). As a central manager, provide maintenance and
operation interface to operator. BSC Functions:
Call Control,Manage the BSC and BTS,Download,Resource management,Test and status management.
Advantages of LGE BSCEasy migration to 1xEV & 4G BSS ALL IP Network,Well adapted to IS-2000,ATM base inter/intra communication network,Support high data rate packet transmission.
