Description
eNodeB healt h checks are divided int o cat egories and are split int o various check point s t hat are
aut onom ous t o each ot her yet a part of a com plet e eNB healt h check. By execut ing t hese healt h check

healt h checks in t his docum ent are read- only and do not im pact perform ance of t he node, wit h t he
except ion of eNB rest art which requires perm ission from node owners, m anagers et c. The page covers
healt h checks regarding eNB H/ W, S/ W, feat ures, power relat ed param et ers, t ransport net work ( MMS, SGW)
