Abstract

Apparatus and methods for guaranteeing a quality of experience (QoE) associated with data provision services in an enhanced data delivery network. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coax infrastructure) is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) via a common service provider. In one exemplary implementation, “over-the-top” voice data services may enable exchange of voice traffic with client devices in the aforementioned network. A distribution node may use a detection rule to identify received packets as voice traffic, and cause a dedicated bearer to attach to the default bearer, thereby enabling delivery of high-quality voice traffic by at least prioritizing the identified packets thereafter and sustaining the delivery even in a congested network environment, and improving the quality of service (QoS) and QoE for the user(s).

First claim

What is claimed is:

1. A computerized network apparatus comprising:
a processor apparatus;
a first data interface in data communication with the processor apparatus; and
a non-transitory computer-readable apparatus comprising a storage device, the storage device comprising a plurality of instructions configured to, when executed by the processor apparatus, cause the computerized network apparatus to:
detect a first plurality of data packets via the first data interface, the first plurality of data packets issued from a server apparatus and received over a first virtualized data channel;
evaluate the first plurality of data packets to determine whether one or more attributes of at least a portion of the first plurality of data packets match at least one criterion;
based at least on a determination that the one or more attributes match the at least one criterion, cause creation of a second virtualized data channel; and
cause the server apparatus to transmit a second plurality of data packets to at least a computerized client device via the second virtualized data channel.

2. The computerized network apparatus of claim 1 , wherein:
the second virtualized data channel comprises a dedicated bearer configure to be logically attached to the first virtualized data channel, the first virtualized data channel comprising a default bearer;
the second virtualized data channel comprises a second QoS Class Identifier (QCI) value that is different from a first QCI value associated with the first virtualized data channel; and
the first and second QCI values are each associated with a respective priority level and a respective packet error loss rate.

3. The computerized network apparatus of claim 1 , wherein the transmission via the second virtualized data channel is characterized by a higher priority than transmission of data packets over the first virtualized data channel.

4. The computerized network apparatus of claim 1 , wherein the computerized network apparatus comprises a 3GPP 3rd Generation Partnership Project) 5G (Fifth Generation) NR (New Radio)-compliant 5GC (5G Core) entity utilized within a hybrid fiber coaxial (HFC) content distribution network.

5. The computerized network apparatus of claim 1 , wherein the evaluation of the first plurality of data packets comprises a detection of metadata associated with the at least portion of the first plurality of data packets that is indicative of the at least portion of the first plurality of data packets having a transport protocol that matches one associated with audio data.

6. The computerized network apparatus of claim 5 , wherein the audio data is configured to be used for at least one over-the-top (OTT) voice application on the at least computerized client device, the at least one OTT voice application configured to utilize Voice over Long Term Evolution (VoLTE) service with the server apparatus.

7. The computerized network apparatus of claim 6 , wherein:
the server apparatus comprises a designated third-party data source configured to provide the at least one OTT voice application; and
the evaluation of the first plurality of data packets comprises a detection of metadata associated with the at least portion of the first plurality of data packets that is indicative of a source Internet Protocol (IP) address that matches the designated third-party data source.

8. A non-transitory computer-readable storage apparatus comprising a storage medium, the storage medium comprising a plurality of instructions configured to, when executed by a processor apparatus, cause a computerized apparatus to:
receive data packets via a first data channel from a network apparatus;
based at least on a determination that metadata associated with the received data packets meets a prescribed detection criterion, cause a second data channel to be created and logically associated to the first data channel; and
cause subsequent data packets from the network apparatus to be transmitted via the second data channel, the second data channel having a higher priority than the first data channel.

9. The non-transitory computer-readable storage apparatus of claim 8 , wherein the determination that the metadata associated with the received data packets meets the prescribed detection criterion comprises a detection that the received data packets utilize a specified transport protocol indicative of voice data.

10. The non-transitory computer-readable storage apparatus of claim 8 , wherein the determination that the metadata associated with the received data packets meets the prescribed detection criterion comprises a detection that a source Internet Protocol (IP) address associated with the received data packets matches one of a prescribed range of known IP addresses associated with at least a third-party server configured to transmit and receive real-time voice data.

11. The non-transitory computer-readable storage apparatus of claim 8 , wherein:
the receipt of the data packets via the first data channel comprises receipt of the data packets from the network apparatus over a 3GPP (3rd Generation Partnership Project) EPS (Evolved Packet System) or 5G (Fifth Generation) NR (New Radio) default bearer; and
the transmission of the subsequent data packets via the second data channel comprises transmission of the subsequent data packets over a 3GPP EPS or 5G NR dedicated bearer attached to the 3GPP EPS or 5G NR default bearer.

12. The non-transitory computer-readable storage apparatus of claim 8 , wherein the plurality of instructions are further configured to, when executed by the processor apparatus, wherein cause the computerized apparatus to:
detect voice traffic associated with a Voice over Internet Protocol (VoIP) application or 3GPP based 3rd Generation Partnership Project (3GPP)-based voice over radio bearer application originating from a server apparatus.

13. The non-transitory computer-readable storage apparatus of claim 8 , wherein the computerized apparatus comprises a 5G (Fifth Generation) NR (New Radio)-compliant core entity associated with a centralized node of a gNB (gNodeB) utilized in association with a hybrid fiber coaxial (HFC) content distribution network.

14. A computerized method for provision of a data service over a data network, the computerized method comprising:
receiving, over at least one first type of data channel, digital data associated with the data service, the digital data originating from a computerized network apparatus;
determining that at least one aspect associated with the digital data meets at least one prescribed criterion;
based at least on the determining, causing instantiation of at least one second type of data channel, the at least one second type of data channel comprising a priority level that is different from a priority level associated with the at least one first type of data channel; and
causing the computerized network apparatus to transmit subsequent digital data via the at least one second type of data channel;
wherein:
the data service comprises an over-the-top (OTT) data service;
the at least one first type of data channel comprises at least one default bearer configured to transmit audio data associated with the OTT data service; and
the at least one second type of data channel comprises at least one dedicated bearer associated to the at least one default bearer upon creation, the at least one dedicated bearer configured to transmit the audio data associated with the OTT data service, the at least one dedicated bearer having a quality-of-service (QoS) level greater than that of the at least one default bearer.
