relation between RNC ID and LAC

[chamanbagga]

What is the relation between RNC ID and LAC? Do we set RNCID == LAC? What do we do if RNC manages multiple LAC?

How many Lac per RNC is based on the supported traffic. For example, in huawei one RNC can supported up to 15k ERL, 1 lac can support up to 200k subscriber. You can have as many LAC or border division as long as it will not past the supported lac and rnc limitation.

Interesting. How do you know these numbers about users, RNC and location area ? LA dimensioning should be based on your paging load entirely. About the first question there is not any relation between RNC ID and LA code, you may set them as you like.Also it is quite common to have few LACs in one RNC this is happend in cases you have high paging load or split LACs based on your strategy and etc...

the number of users should be based on vendor and the spu loading.

I've never heard about limitation factor based on number of users in the RNC especially for Huawei, for traffic volume yes. Give more info/document?

RNC ID does not necessarily have a connection to LAC ID - it depends how the network is planned. For example you can find in teh same RNC (12) LACs 33, 21 and 78 - no connection between them. If the planners didn't use their heads when doing this too bad.

No relative connection of RNCIDs and LAC. This is based on how to plan the network. LAC depends on paging. RNCID is same as SiteIDs. It only serves as identification.
