Abstract
A core network node (e.g., Serving GPRS Support Node), a radio access network node (e.g., Base Station Subsystem) and various methods are described herein for implementing longer paging cycles (e.g., Extended Discontinuous Receive (eDRX) cycles) for wireless devices in a wireless communication network.
Claims26
A core network (CN) node configured to interact with a radio access network (RAN) node and a wireless device, the CN 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 CN node is operable to:
- register the wireless device;
- receive an Internet Protocol (IP) packet destined for the wireless device;
- buffer the IP packet for a predetermined time;
- calculate a next occurrence of a nominal paging group for the wireless device;
- transmit a page request associated with the wireless device to the RAN node, wherein the page request is transmitted before the next occurrence of the nominal paging group for the wireless device;
- receive a page response from the RAN node;
- and
- upon receipt of the page response, transmit the IP packet to the RAN node for delivery to the wireless device.
A method in a core network (CN) node configured to interact with a radio access network (RAN) node and a wireless device, the method comprising:
- registering the wireless device;
- receiving an Internet Protocol (IP) packet destined for the wireless device;
- buffering the IP packet for a predetermined time;
- calculating a next occurrence of a nominal paging group for the wireless device;
- transmitting a page request associated with the wireless device to the RAN node, wherein the page request is transmitted before the next occurrence of the nominal paging group for the wireless device;
- receiving a page response from the RAN node;
- and
- upon receipt of the page response, transmitting the IP packet to the RAN node for delivery to the wireless device.
A radio access network (RAN) node configured to manage one or more cells and further configured to interact with a wireless device and a core network (CN) node, 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 radio access network node is operable to:
- transmit, to the CN node, a registration request associated with the wireless device;
- receive, from the CN node, a first page request associated with the wireless device, wherein the first page request is received before a next occurrence of a nominal paging group for the wireless device;
- and,
- calculate the next occurrence of the nominal paging group for the wireless device using information in the first page request.
A method in a radio access network (RAN) node configured to manage one or more cells and further configured to interact with a wireless device and a core network (CN) node, the method comprising:
- transmitting, to the CN node, a registration request associated with the wireless device;
- receiving, from the CN node, a first page request associated with the wireless device, wherein the first page request is received before a next occurrence of a nominal paging group for the wireless device;
- and,
- calculating the next occurrence of the nominal paging group for the wireless device using information in the first page request.
