LSAcannotbeusedwithstandardphase1orphase2mobilestations(orwithnon-compatiblephase2+mobile
stations)withallserviceaspects.AdedicatedmobilestationwithLSAcapabilityisrequired.
Acompatiblemobilestationshallprovidethefollowingspecificfunctions:
cellreselectionincaseofaLSAsubscription;
notificationofthecurrentLSA.
AmobilestationwithLSAcapabilityshallalsoprovidethecompletefunctionalityinordertoallowtheuseofphase2
services.
Standardphase1andphase2mobilestationsinanetworkshallnotbeimpactedbythepresenceofLSAservicesinthat
networkduetoLSAsignalling,alsoifthemobilestationisoperatedwithaSIMthatcontainsSoLSAfields.
However,ifLSAisprovidedinanetwork,itcanbeappliedtonon-compatiblemobilestationsinthefollowingway:
