Binding update forwarding between packet gateways
First Claim
1. A method comprising:
- receiving, by a first home packet gateway (PGW) device, a binding update message on behalf of a wireless communication device (WCD), wherein the first home PGW device is associated with a first pool of Internet Protocol (IP) addresses from which the first home PGW device assigns IP addresses to WCDs served by the first home PGW device, and wherein the WCD is assigned a particular IP address;
in response to receiving the binding update message, determining that the first pool of IP addresses does not include the particular IP address;
in response to determining that the first pool of IP addresses does not include the particular IP address, determining that the particular IP address is included in a second pool of IP addresses that is associated with a second home PGW device, wherein the second home PGW device assigns IP addresses from the second pool of IP addresses to WCDs served by the second home PGW device; and
in response to determining that the particular IP address is included in the second pool of IP addresses that is associated with the second home PGW device, forwarding, by the first home PGW device, the binding update message to the second home PGW device.

Abstract
A first home packet gateway (PGW) device may receive a binding update message on behalf of a wireless communication device (WCD). The first home PGW device may be associated with a first pool of Internet Protocol (IP) addresses, and the WCD may be assigned a particular IP address. It may be determined that the first pool of IP addresses does not include the particular IP address, and that the particular IP address is included in a second pool of IP addresses that is associated with a second home PGW device. Possibly in response to determining that the particular IP address is included in the second pool of IP addresses that is associated with the second home PGW device, the first home PGW device may forward the binding update message to the second home PGW device.

10. An article of manufacture including a non-transitory computer-readable medium, having stored thereon program instructions that, upon execution by a first home packet gateway (PGW) device, cause the first home PGW device to perform operations comprising:
-
receiving a binding update message on behalf of a wireless communication device (WCD), wherein the first home PGW device is associated with a first pool of Internet Protocol (IP) addresses from which the first home PGW device assigns IP addresses to WCDs served by the first home PGW device, and wherein the WCD is assigned a particular IP address; in response to receiving the binding update message, determining that the first pool of IP addresses does not include the particular IP address; in response to determining that the first pool of IP addresses does not include the particular IP address, determining that the particular IP address is included in a second pool of IP addresses that is associated with a second home PGW device, wherein the second home PGW device assigns IP addresses from the second pool of IP addresses to WCDs served by the second home PGW device; and in response to determining that the particular IP address is included in the second pool of IP addresses that is associated with the second home PGW device, forwarding the binding update message to the second home PGW device. - View Dependent Claims (11, 12, 13, 14, 15)

16. A first home packet gateway (PGW) device comprising:
-
at least one processor; memory; and program instructions, stored in the memory, that upon execution by the at least one processor cause the first home PGW device to perform operations comprising; receiving a binding update message on behalf of a wireless communication device (WCD), wherein the first home PGW device is associated with a first pool of Internet Protocol (IP) addresses from which the first home PGW device assigns IP addresses to WCDs served by the first home PGW device, and wherein the WCD is assigned a particular IP address; in response to receiving the binding update message, determining that the first pool of IP addresses does not include the particular IP address; in response to determining that the first pool of IP addresses does not include the particular IP address, determining that the particular IP address is included in a second pool of IP addresses that is associated with a second home PGW device, wherein the second home PGW device assigns IP addresses from the second pool of IP addresses to WCDs served by the second home PGW device; and in response to determining that the particular IP address is included in the second pool of IP addresses that is associated with the second home PGW device, forwarding the binding update message to the second home PGW device. - View Dependent Claims (17, 18, 19, 20)
