Abstract
Systems and methods are provided for traffic aware slice management in a wireless network. A method includes receiving a request from a wireless device at an access node and tagging the request at the access node with a priority. The method additionally includes transmitting the tagged request to a policy mapper of a core network and receiving a policy from a core network policy mapper based on the tagged request. The method further includes scheduling the request based on the received policy.
Claims20
A method comprising:
- receiving a request from a wireless device at an access node, the request associated with a traffic type;
- tagging the request from the wireless device at the access node with a priority based on the traffic type and transmitting, by the access node, the tagged request to a policy mapper of a core network;
- receiving a policy from a core network policy mapper based on the tagged request, the policy from the core network policy mapper allocating at least one network slice based on the priority of the tagged request;
- and
- scheduling the request at the access node based on the received policy allocating the at least one network slice.
2 more elements
A system comprising:
- an access node receiving requests from wireless devices, the access node comprising a tagging processor, the tagging processor tagging the received requests from wireless devices with a priority selected based on a traffic type;
- and
- a core network receiving the tagged requests from the access node, the core network comprising a policy mapper associating the tags with a predetermined policy corresponding to at least one network slice and transmitting the predetermined policy corresponding to the at least one network slice to the access node in response to receipt of the tagged request,
- wherein the access node schedules the request based on the predetermined policy corresponding to the at least one network slice received from the policy mapper of the core network.
1 more element
A centralized policy mapper comprising:
- a memory storing a policy map in a core network;
- and
- a processor in the core network performing steps including;
- receiving a tagged request from an access node, the request originating from a wireless device and tagged with a priority by the access node based on a traffic type;
- matching the tagged request with a policy from the stored policy map based on the priority;
- and
- transmitting the stored policy for the tagged request to the access node, the stored policy allocating at least one network slice to the tagged request.
