>MBMS required UE action |
MP |
Enumerated (None, Acquire counting info, Acquire counting info – PTM RBs unmodified, Acquire PTM RB info, RequestPTP RB, Release PTM RB) |
Indicates required UE action upon receiving the message. When sent on the DCCH, only the following values apply: None, Acquire PTM RB info, request PTP RB). If the cell is operating in MBSFN mode as indicated in subclause 8.1.1.6.3 all values except “Acquire PTM RB info” and "Release PTM RB" are handled as if “None” was received. |

MBMS number of neighbour cells |
MP |
Integer (0..32) |
Indicates the number of MBMS NEIGHBOURING CELL P-T-M RB INFORMATION messages that are contained within the MCCH transmission. Not applicable when sent on the DCCH. If the cell is operating in MBSFN mode as indicated in subclause 8.1.1.6.3 the UE behaves as if the value 0 was received. |

Condition |
Explanation |
|
MCCH |
This IE is mandatory present if the message is sent via MCCH and not needed otherwise. |
|
DCCH |
This IE is mandatory present if the message is sent via DCCH and not needed otherwise. |
|
MCCHOP |
This IE is optionally present if the message is sent via MCCH and not needed otherwise. |
|
DCCHCH |
This IE is present conditionnaly on history if the message is sent via DCCH and not present otherwise. |
|
MBSFN |
This IE is mandatory default when the cell on which this IE is sent is operating in MBSFN mode according to subclause 8.1.1.6.3. Otherwise the IE is not needed. |
|
PTM_RB_RELEASE_LCR_TDD |
This IE is optionally present if the IE “MBMS required UE action” has the value “Release PTM RB”. Otherwise it is not needed. For 1.28 Mcps TDD only. |
