SYSTEMS AND METHOD FOR OFFLOADING COMMUNICATION SESSIONS TO LOCAL NETWORK RESOURCES
First Claim
1. A method performed by one or more network devices, comprising:
- establishing, by the one or more network devices, a communication session involving user devices by routing the communication session through a core network of a wireless telecommunications network;
determining, by the one or more network devices, that the user devices are both attached to a single radio access network (RAN) of the wireless telecommunications network;
identifying, by the one or more network devices, the RAN to which the user devices are attached; and
causing, by the one or more network devices, the communication session to be routed locally by the RAN such that information sent between user devices during a remainder of the communication session is not routed through the core network.

Abstract
Techniques described herein may be used to identify communication sessions (e.g., voice calls, video calls, etc.) that can be routed using local network resources, such as a base station to which the user devices are attached, and cause routing responsibilities for the session to be offloaded to the local network resources. Doing so may conserve network resources by alleviating the core network from having to support communication sessions that do not need to be routed through the core network. In turn, this may reduce the potential for network latency since: 1) core network resources will be more available to support sessions that actually need to be routed through the core network; and 2) sessions that do not need to be routed through the core network can be routed over shorter distances that involve fewer network devices (e.g., a based station).

8. One or more network devices, comprising:
-
a non-transitory memory device storing a plurality of processor-executable instructions; and a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the processor to; establish a communication session involving user devices by routing the communication session through a core network of a wireless telecommunications network; determine that the user devices are both attached to a single radio access network (RAN) of the wireless telecommunications network; identify the RAN to which the user devices are attached; and cause the communication session to be routed locally by the RAN such that information sent between the user devices during a remainder of the communication session is not routed through the core network. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. One or more network devices, comprising:
-
a non-transitory memory device storing a plurality of processor-executable instructions; and a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the processor to; create network address translation (NAT) information describing information sent between user devices during a call involving a core network of a wireless telecommunications network; determine, based on the NAT information, that the user devices are both attached to a single Enhanced Node B (eNB) of the wireless telecommunications network; identify the eNB to which the user devices are attached; and generate a notification that the users devices are both attached to the single eNB to enable the call to be routed locally by the eNB and not the core network. - View Dependent Claims (16, 17, 18, 19, 20)
