Abstract
A user equipment (UE) in an idle or inactive state receives system information indicating, per service class, service-suitable frequencies, a priority adjustment and a pre-access reselection budget. Upon a service trigger (a non-access-stratum service indication, a predicted service onset, or a paging message carrying an intended-service index), the UE starts a validity timer and raises the reselection priority of the service-suitable frequencies up to a cap. It holds access for at most the budget while reselecting. If the budget expires before the UE camps on a service-suitable cell, the UE accesses the camped cell with a service-layer miss indication naming the service class, the best measured suitable frequency and a cause, and starts a suppression timer. The network node redirects the UE and adapts the budget, adjustment or threshold from the miss ratio. The UE reverts to default priorities on validity or linger expiry.
