6.1 General

The Packet Paging procedure is always initiated upon request by RRC. RRC shall provide all the necessary information to construct a PACKET PAGING REQUEST message. The MAC layer shall include in the PACKET PAGING REQUEST message all information received from the RRC layer. A number of mobile stations can be paged in the same paging message.

On receipt of a PACKET PAGING REQUEST message, the MAC shall forward all received information for this mobile station to RRC.

6.2 Paging initiation in MAC-Idle state

In MAC-Idle state and upon request from RRC, the MAC layer initiates the Packet Paging procedure by transmitting a PACKET PAGING REQUEST message on an appropriate paging subchannel on the PCCCH, taking into account the DRX parameters valid for each targeted mobile station (see sub-clause 5.4.1.8).

The following IEs shall be included in the in the PACKET PAGING REQUEST message. RRC determines the values of the IEs (see 3GPP TS 44.118).

– MS Identity (IMSI, TMSI, P-TMSI or G-RNTI).

The following IEs may be included in the in the PACKET PAGING REQUEST message. RRC determines which IEs to include and their values (see 3GPP TS 44.118).

– CN domain identity.

– Paging cause.

– Paging Record Type Identifier.

6.3 Paging initiation in MAC-Shared state

In MAC-Shared state and upon request from RRC, the MAC layer initiates the paging procedure by transmitting a PACKET PAGING REQUEST message on the PACCH.

The following IEs shall be included in the in the PACKET PAGING REQUEST message. RRC determines the values of the IEs (see 3GPP TS 44.118).

– MS Identity (IMSI, TMSI, P-TMSI or G-RNTI).

The following IEs may be included in the in the PACKET PAGING REQUEST message. RRC determines which IEs to include and their values (see 3GPP TS 44.118).

– CN domain identity.

– Paging cause.

– Paging Record Type Identifier.

6.4 Reception of PACKET PAGING REQUEST by an MS

Upon reception of a PACKET PAGING REQUEST message on either PCCCH or PACCH, the MAC shall forward all received information for this mobile station to RRC.
