Can a eNB belongs to multiple tracking area if the eNB is shared between two operator under e-UTRAN sharing model ?

Question

Suppose a eNB is shared between two operators so can he have multiple tracking area code ?

Answer 1

System Information Block-1 (SIB1) broadcasts only one tracking area code in cell. It means one cell can't be part of two different tracking area. SIB1 can also carry max to 6 PLMNs. All these PLMNs can belong to same MME or different MMEs in case of network sharing.

As per my understanding of cell level and SIB1 details, if a cell is being shared between multiple operator then both the network will have to consider tracking area a common tracking area. A single cell can't belong to different different operator's tracking area.

I may not be correct, lets others to respond.

Thanks, just to add point Tracking area is at eNB level, it means tracking area is assigned to an eNB so all the cells belongs to same tracking area.

@sachidananda,    cells in a eNodeB can have different TA.    i.e TA can be at cell level also in an eNodeB.

Okay Thanks for the information.
