RTP Pool Configuration

One of the steps in establishing a RTP session between the UE and the core network through HNB and HNB-GW
service running on the system is that upon successful authentication, the UE is assigned an RTP IP address. The IP
address could be dynamically assigned from a pool that is configured on the system. It may also be an address that is
statically configured in the user profile or even one that is requested by the subscriber.
IP addresses can be dynamically assigned from a single pool/a group of IP pools/a group of IP pool groups. The
addresses/IP pools/ IP pool groups are placed into a queue in each pool or pool group. An address is assigned from the
head of the queue and, when released, returned to the end. This method is known as least recently used (LRU).
When a group of pools have the same priority, an algorithm is used to determine a probability for each pool based on the
number of available addresses, then a pool is chosen based on the probability. This method, over time, allocates
addresses evenly from the group of pools.

used more frequently.
To configure the RTP IP pool:
Step 1
Create the RTP IP pool for IPv4 addresses in source context for RTP pool allocation over Iuh interface by applying the
example configuration in the IPv4 RTP Pool Creation Over IuCS section.
Step 2
Create the RTP IP pool for IPv4 addresses in destination context for RTP pool allocation over IuCS interface by
applying the example configuration in the IPv4 RTP Pool Creation Over Iuh section.
Step 3
Verify your RTP IP pool configurationby applying the example configuration in the RTP IP Pool Configuration
Verification section.
Step 4
Save your configuration as described in the Saving Your Configuration chapter.

IPv4 RTP Pool Creation Over IuCS
