The network node next transmits, as part of the random-access procedure, a Msg2 transmission to the wireless device associated with the identity corresponding to the contention-free preamble. The Msg2 transmission includes a signaling message and downlink data.

Abstract: In a wireless communication network that implements the RRC Resume procedure, an eNB sends to a radio network device, previously connected, given a Resume ID, a paging message or Random Access Response message including an RRC Resume directive. The RRC Resume directive comprises at least an indication whether or not the radio network device should perform an RRC Resume procedure. If RRC Resume directive indicates the radio network device should not perform an RRC Resume procedure, the radio network device performs an RRC Connection procedure. If the RRC Resume directive indicates the radio network device should perform an RRC Resume procedure, it may include additional information to optimize or otherwise assist the RRC Resume procedure. In this manner, RRC Resume signaling is avoided when the eNB knows that it will not be successful, such as if a prior RRC connection context is not available or readily retrievable, or is invalid.
