Paging in Coverage Extension Mode
First Claim
52. 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; and
initiating paging of the user terminal according to the second paging mode, in response to said determining.

Abstract
Techniques and apparatus 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. An example method includes first determining (810) that the second paging mode is needed for a user terminal, and then initiating (820) paging of the user terminal according to the second paging mode, in response to said determining. In some embodiments, the node is a mobility management node, and initiating paging of the user terminal comprises 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 comprises transmitting one or more paging messages using a message format corresponding to the second paging mode.

77. A method in a user terminal 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 user terminal should monitor for paging messages according to the second paging mode by evaluating an operational history for the user terminal with respect to operation in a coverage extension mode; and responsive to said determining, monitoring for paging messages according to the second paging mode. - View Dependent Claims (78, 79, 80)
