Abstract

A method, a system, and a non-transitory storage medium provide for encoding a general packet radio service (GPRS)-tunnel endpoint identifier (GTP-TEID) with data identifying radio frequency (RF) bandwidths supported in a local radio environment (LRE) from which a user equipment (UE) device accesses the wireless access station; sending, via a signaling channel, the GTP-TEID to a core network device; notifying one or more core network devices of an RF bandwidth category level corresponding to the RF bandwidths; and applying at least one of a policy rule or a charging rule to a packet data unit (PDU) session for the UE device, based on the RF bandwidth category level.

First claim

What is claimed is:

1. A method comprising:
sending, by a radio access network (RAN) to a core network device, a first general packet radio service (GPRS)-tunnel endpoint identifier (GTP-TEID) that identifies first radio frequency (RF) bandwidths supporting a first dedicated radio bearer (DRB) in the RAN, wherein multiple presence reporting areas (PRAs) define a coverage area within the RAN;
mapping an RF bandwidth category level to each PRA, wherein the RF bandwidth category levels include multiple values that differ;
notifying, by the core network device, other core network devices of a first RF bandwidth category level corresponding to the first RF bandwidths; and
applying, by the other core network devices, at least one of a first traffic shaping policy or a first charging rule to the first DRB based on the first RF bandwidth category level.

2. The method of claim 1 , further comprising:
sending, to the core network device, a second GTP-TEID that identifies second RF bandwidths supporting a second DRB in the RAN, wherein the second RF bandwidths differ from the first RF bandwidths;
notifying other core network devices of a second RF bandwidth category level corresponding to the second RF bandwidths; and
applying at least one of a second traffic shaping policy or a second charging rule to the second DRB based on the second RF bandwidth category level.

3. The method of claim 2 , further comprising:
encoding the first GTP-TEID with a first extension identifying a first local radio environment (LRE); and
encoding the second GTP-TEID with a second extension identifying a second LRE.

4. The method of claim 3 , further comprising:
analyzing the first LRE and the second LRE; and
generating, based on results of the analyzing, a first PRA and a second PRA.

5. The method of claim 1 , wherein the other core network devices comprise a policy control function (PCF) device and a charging function (CHF) device.

6. The method of claim 1 , further comprising:
selecting at least one of quality of service (QoS), a network slice identifier, charging, traffic management, data shaping, or other policies based on a first PRA and a second PRA.

7. The method of claim 1 , wherein the core network device comprises a session management function (SMF) device.

8. A system comprising:
at least one radio access network (RAN) device comprising a processor, wherein the at least one RAN device is configured to:
send, to a core network device, a first general packet radio service (GPRS)-tunnel endpoint identifier (GTP-TEID) that identifies first radio frequency (RF) bandwidths supporting a first dedicated radio bearer (DRB) in a RAN, wherein multiple presence reporting areas (PRAs) define a coverage area within the RAN;
map an RF bandwidth category level to each PRA, wherein the RF bandwidth category levels include multiple values that differ;
notify other core network devices of a first RF bandwidth category level corresponding to the first RF bandwidths; and
direct the other core network devices to apply at least one of a first traffic shaping policy or a first charging rule to the first DRB based on the first RF bandwidth category level.

9. The system of claim 8 , wherein the at least one RAN device is further configured to:
send, to the core network device, a second GTP-TEID that identifies second RF bandwidths supporting a second DRB in the RAN, wherein the second RF bandwidths differ from the first RF bandwidths;
notify other core network devices of a second RF bandwidth category level corresponding to the second RF bandwidths; and
apply at least one of a second traffic shaping policy or a second charging rule to the second DRB based on the second RF bandwidth category level.

10. The system of claim 8 , wherein the at least one RAN device is further configured to:
encode the first GTP-TEID with a first extension identifying a first local radio environment (LRE); and
encode the second GTP-TEID with a second extension identifying a second LRE.

11. The system of claim 10 , wherein the at least one RAN device is further configured to:
analyze the first LRE and the second LRE; and
generate, based on results of the analyzing, a first PRA and a second PRA.

12. The system of claim 8 , wherein the other core network devices comprise a policy control function (PCF) device and a charging function (CHF) device.

13. The system of claim 8 , wherein the at least one RAN device is further configured to:
select at least one of quality of service (QoS), a network slice identifier, charging, traffic management, data shaping, or other policies based on a first PRA and a second PRA.

14. The system of claim 8 , wherein the core network device comprises a session management function (SMF) device.

15. A non-transitory computer-readable storage medium storing instructions executable by a processor of a radio access network (RAN) device, which when executed cause the RAN device to:
send, to a core network device, a first general packet radio service (GPRS)-tunnel endpoint identifier (GTP-TEID) that identifies first radio frequency (RF) bandwidths supporting a first dedicated radio bearer (DRB) in a RAN, wherein multiple presence reporting areas (PRAs) define a coverage area within the RAN;
map an RF bandwidth category level to each PRA, wherein the RF bandwidth category levels include multiple values that differ;
notify other core network devices of a first RF bandwidth category level corresponding to the first RF bandwidths; and
direct the other core network devices to apply at least one of a first traffic shaping policy or a first charging rule to the first DRB based on the first RF bandwidth category level.

16. The non-transitory computer-readable storage medium of claim 15 , wherein the instructions further cause the RAN device to:
send, to the core network device, a second GTP-TEID that identifies second RF bandwidths supporting a second DRB in the RAN, wherein the second RF bandwidths differ from the first RF bandwidths;
notify other core network devices of a second RF bandwidth category level corresponding to the second RF bandwidths; and
apply at least one of a second traffic shaping policy or a second charging rule to the second DRB based on the second RF bandwidth category level.

select at least one of quality of service (QoS), a network slice identifier, charging, traffic management, data shaping, and/or other policies based on a first PRA and a second PRA.
