Paging for Longer Paging Cycles

Abstract

A radio network node receives a page request from a core network node. The page request indicates to page a wireless communication device. The radio network node determines a next occurrence of a monitoring window during which the wireless communication device will monitor a paging channel associated with the radio network node. If the amount of time until the next occurrence of the monitoring window exceeds an amount of time that the radio network node can store the page request, the radio network node discards the page request and sends a response to the core network node indicating that the page request was discarded; the response includes a paging timer value that indicates when the core network node should repeat the page request.

         29 . A wireless communication device comprising one or more processors and memory, the memory containing instructions executable by the one or more processors, whereby the wireless communication device is operable to:
 monitor a paging channel associated with a radio network node according to a first monitoring window, the first monitoring window having a periodicity that corresponds to a long paging cycle;   receive a paging request message from the radio network node, wherein the paging request message includes an indication of a time period T 1  during which the wireless communication device is to use a second monitoring window, the second monitoring window having a periodicity that corresponds to a legacy paging cycle;   monitor the paging channel according to the second monitoring window until the time period T 1  elapses; and,   monitor the paging channel according to the first monitoring window after the time period T 1  elapses.   
     
     
         30 . The wireless communication device of  claim 29 , further operable to transmit an acknowledgement to the radio network node that the wireless communication device received the indication of the time period T 1 . 
     
     
         31 . The wireless communication device of  claim 29 , further operable to set a legacy window timer to the time period T 1 . 
     
     
         32 . The wireless communication device of  claim 29 , wherein
 the legacy paging cycle corresponds to a paging cycle supported by specification 3GPP TS 44.018 version 12.1.0; and   the long paging cycle corresponds to a paging cycle longer than what is supported by specification 3GPP TS 44.018 version 12.1.0.   
     
     
         33 . A method in a wireless communication device, comprising:
 monitoring a paging channel associated with a radio network node according to a first monitoring window, the first monitoring window having a periodicity that corresponds to a long paging cycle;   receiving a paging request message from the radio network node, wherein the paging request message includes an indication of a time period T 1  during which the wireless communication device is to use a second monitoring window, the second monitoring window having a periodicity that corresponds to a legacy paging cycle;   monitoring the paging channel according to the second monitoring window until the time period T 1  elapses; and,   monitoring the paging channel according to the first monitoring window after the time period T 1  elapses.   
     
     
         34 . The method of  claim 33 , further comprising transmitting an acknowledgement to the radio network node that the wireless communication device received the indication of the time period T 1 . 
     
     
         35 . The method of  claim 33 , further comprising setting a legacy window timer to the time period T 1 . 
     
     
         36 . The method of  claim 33 , wherein
 the legacy paging cycle corresponds to a paging cycle supported by specification 3GPP TS 44.018 version 12.1.0; and   the long paging cycle corresponds to a paging cycle longer than what is supported by specification 3GPP TS 44.018 version 12.1.0.
