This TS specifies the stage 1 description of the enhanced Multi Level Precedence and Pre emption Service (eMLPP). This service has two parts: precedence and pre emption. Precedence involves assigning a priority level to a call in combination with fast call set up. Pre emption involves the seizing of resources, which are in use by a call of a lower precedence, by a higher level precedence call in the absence of idle resources. Pre emption can also involve the disconnection of an on going call of lower precedence to accept an incoming call of higher precedence.

The eMLPP service is provided as a network operator's option to a domain of a network. The domain can be the whole network or a subset of the network. The eMLPP service applies to all network resources in the domain that is in common use. The eMLPP service is applicable to all mobile stations in the domain with all or some mobile stations having a respective subscription assigning precedence according to the eMLPP service.

eMLPP is a supplementary service and shall be provided to a subscriber for all basic services subscribed to and for which eMLPP applies.
