11.1 Precautions to be taken in a multisite configuration
11.1.1 Contiguous multi-site configuration
For practical and operational reasons, it is essential to declare different cell numbers in the
various sites (by allocating a range of numbers to each site). This is because in a multi-site
configuration two neighbouring cells cannot have the same cell number and thus the same base
station number.
The following MMCs must be implemented.
• Declare the same PARI on all the sites.
• Same RANDOM registration number on all the sites.
• Same RS registration number on all the sites.
• Same MOBILE registration password on all the sites.
Example MMCs for a contiguous multi-site configuration
Creating a three-site configuration with three cells each.
•Site1
• Cell 00 associated with trunk group 0 Base stations 00 to 07
• Cell 01 1 08 to 0F
• Cell 02 2 10 to 17
•Site 2
• Cell 10 associated with trunk group 0 Base stations 18 to 1F
• Cell 11 1 20 to 27
• Cell 12 2 28 to 2F
•Site 3
• Cell 20 associated with trunk group 0 Base stations 30 to 37
• Cell 21 1 38 to 3F
• Cell 22 2 40 to 47
It is not necessary to give the trunk groups different numbers in the different sites: the trunk
group represents the resources in the cell of each site.
