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.
HUAWEI TECHNOLOGIES CO., LTD. Page 40All rights reserved
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.
