Claim of US Patent No. 10,172,183

1. A radio access network (RAN) node configured to interact with a core network (CN) node to time coordinate cells and maintain a reliability of paging a wireless device, the RAN node comprising:a processor; and,
a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the RAN node is operable to:
receive a paging request from the CN node, wherein the paging request includes information associated with the wireless device;
calculate, using at least the information associated with the wireless device, a time remaining until a next paging opportunity for the wireless device within the cells comprising a paging area of the wireless device; and,
transmit a paging response to the CN node, wherein the paging response includes the time remaining until a next paging opportunity for the wireless device,
wherein the information comprises the following:
an International Mobile Subscriber Identity (IMSI) of the wireless device;
an extended Discontinuous Receive (eDRX) cycle length of the wireless device; and
a coverage class of the wireless device.
