WCDB

� It provides UMG resource management, outgoing trunk selection, and

WVDB distribution agent management (MSRN number allocation, WVDB

maintenance command forwarding) functions.

� The WCDB contains global data which can be accessed by all

WCCUs/WCSUs and WVDBs.

� Because the WCDB is an accessed center, its load is relatively large. In

small-capacity configuration mode, its functions can be implemented by

one pair of WCDBs.

� In a large-capacity configuration mode, different functions must be

distributed to different WCDBs.


WVDB

� The VLR Database Board (WVDB) is a front board used to store the

subscription data of mobile subscribers.

� In a large-capacity application, multiple pairs of WVDBs are required to

store the subscription data.

� The subscription information of one subscriber is stored in the same pair

of WVDBs.

� The principles for distributing subscriber data on different WVDBs have

been described in the Section about WCDB (also named WVDB

distribution agent function).

� Such distribution is transparent for the WCCU/WCSU service layer.


WMGC

� WMGC provides gateway registration, internal link status maintenance,

gateway status and capability auditing, and gateway exception handling

functions.

WALU&UPWR

�The Alarm Unit (WALU) is a front board installed fixedly in slot 16 in

indicator under the instructions of the WSMU.

�UPWR

�It is used to provide power supply to the boards in the MSC

SERVER UNIT frames.

�The UPWR works in 2+2 backup mode.
