RADIO COMMUNICATION SYSTEM FOR ASSIGNING A SHORT-LIVED C-RNTI

摘要

A radio communication system and a method for assigning a short-lived Cell Radio Network Temporary Identifier (C-RNTI) to a first user equipment performing random access to a radio network node are provided. The radio communication system registers the first user equipment as connected to the radio network node. A message for synchronizing the radio network node and the first user equipment with respect to the first time period is transferred. After the first time period has elapsed, the radio communication system maintains the first user equipment connected to the radio network node, and allows the short-lived C-RNTI to be assigned to a second user equipment. Furthermore, a first user equipment and method for enabling assignment of a short-lived C-RNTI to the first user equipment performing random access and a radio network node and method for assigning a short-lived C-RNTI to a first user equipment performing random access are provided.

1. A method in a radio communication system for assigning a short-lived Cell Radio Network Temporary Identifier (C-RNTI) to a first user equipment performing random access to a radio network node, wherein the method comprises:
registering the first user equipment as connected to the radio network node, wherein the short-lived C-RNTI is assigned to the first user equipment for identification thereof during a first time period; and transferring, from the radio network node to the first user equipment, a message for synchronizing the radio network node and the first user equipment with respect to the first time period; and after the first time period has elapsed:
maintaining the first user equipment connected to the radio network node; andallowing the short-lived C-RNTI to be assigned to a second user equipment, thereby enabling use of the short-lived C-RNTI for identification of the second user equipment when connected to the radio network node.
