10.2.16e MBMS Access Information

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

This message is transmitted periodically by UTRAN to inform UEs that have joined or selected a particular MBMS service about the need to establish an RRC connection or to perform a cell update. While the message contents may change within a modification period, all occurances of the information within a modification period concern the same MBMS service(s). If the cell on which this message is sent is operating in MBSFN mode as indicated in subclause 8.1.1.6.3 the UE behaves as if this message would not have been received.

>Access probability factor – Idle

MP

Integer (0 to 960 by step of 32, 1000)

Access probability factor for UEs in idle mode. The actual Access Probability (AP) is a function of the Access Probability Factor (APF):

AP (APF) = 2-(APF/100)

REL-6

>Access probability factor – connected

MD

Integer (0 to 960 by step of 32, 1000)

Access probability factor for UEs in connected mode. The actual Access Probability (AP) is a function of the Access Probability Factor (APF):

AP (APF) = 2-(APF/100)

Default value is the value included in IE "Access probability factor – Idle"
