ARP

ARP is expanded two ways:

1. Address Resolution Protocol

   ARP is a TCP/IP protocol used to convert an IP address into a physical address, such as an Ethernet address.

2. allocation and retention priority

   An EPS bearer QoS parameter that prioritizes bearer establishment or modification requests when resources are limited. An ARP can determine that existing bearers with a relatively low priority should be dropped to free up needed resources. An ARP can also determine whether a bearer should be dropped by another bearer with a higher priority. See 3GPP TS 23.203
