Paging in coverage extension mode
First Claim
1. A method, in a node of a wireless communication network, for supporting paging of user terminals by a base station that supports first and second paging modes, the second paging mode providing extended coverage relative to the first paging mode and using more resources than the first paging mode, the method comprising:
- determining that the second paging mode is needed for a user terminal, wherein determining that the second paging mode is needed for the user terminal comprises receiving a message ordering the base station to page the user terminal according to the second paging mode; and
initiating paging of the user terminal according to the second paging mode, in response to said determining, wherein initiating paging of the user terminal according to the second paging mode comprises transmitting one or more paging messages for the user terminal, using a message format corresponding to the second paging mode, and wherein the message orders the base station to first page the user terminal according to the first paging mode and to then page the user terminal according to the second paging mode in the event that paging the user terminal according to the first paging mode is unsuccessful.

Abstract
A method for supporting paging of user terminals by a base station that supports first and second paging modes, the second paging mode providing extended coverage relative to the first paging mode and using more resources than the first paging mode is provided. The method includes determining that the second paging mode is needed for a user terminal, and then initiating paging of the user terminal according to the second paging mode, in response to the determining. In some embodiments, the node is a mobility management node, and initiating paging of the user terminal includes sending, to the base station, a message ordering the base station to page the user terminal according to the second paging mode. In other embodiments, the node is the base station, and initiating paging includes transmitting one or more paging messages using a message format corresponding to the second paging mode.
