Definitions

  • Various example embodiments relate to the field of communication systems and, in particular, to radio access networks.
  • Next generation networks such as Fifth Generation (5G) denote the next major phase of mobile telecommunications standards beyond Fourth Generation (4G) standards.
  • next generation networks may be enhanced in terms of radio access and network architecture.
  • a Radio Access Network (RAN) is part of a mobile communication system that uses radio access technology to provide wireless connectivity to mobile devices or devices with fixed location (e.g., User Equipment (UE)), and connects the mobile devices with a core network to receive services.
  • UE User Equipment
  • 5G systems are envisioned to implement time-sensitive applications, such as gaming, Augmented reality (AR) and Virtual Reality (VR), live video streaming, network- assisted control of autonomously guided vehicles (AGV), network-assisted control of mobile robots in a factory, etc.
  • AR Augmented reality
  • VR Virtual Reality
  • AVG autonomously guided vehicles
  • One problem for carriers is to provide efficient operation and optimal use of resources within the RAN in providing services, such as application services. Many times, service degradation experienced by subscribers is due to congestion and signal related issues in the RAN. Thus, the performance of resources in a RAN is integral to delivering a quality experience to a subscriber.
  • an application client on a UE may access an application service over a RAN and other intervening networks.
  • a RAN controller is able to retrieve Key Performance Metrics (KPM) of one or more RAN nodes that serve a session between the application client and the application service, and provide the KPM to the application service (or to its associated provider).
  • KPM may include, for example, UE throughput, packet latency, jitter, or loss, radio resource utilization, etc.
  • a token exchange mechanism is introduced herein where a newly-defined identification token is generated by the UE/application client, and the identification token is known within the RAN and shared with the application service.
  • the identification token is mapped to the KPM collected from the RAN node(s) that serves the session.
  • the application service may therefore correlate the KPM with an application service flow, and the application service may be adapted based on the KPM.
  • One technical benefit is the performance of the application service may be optimized based on RAN conditions to provide an improved experience to a subscriber.
  • a RAN controller of a RAN is configured to provide radio service to User Equipment (UE).
  • the RAN controller comprises at least one processor and at least one memory storing instructions that, when executed by the at least one processor, cause the RAN controller at least to receive a request from an application service for performance metrics of an application service flow between the application service and an application client hosted by the UE, receive an identification token from the application service that identifies one or more data radio bearers of the RAN serving the application service flow, receive a report message from one or more RAN nodes of the RAN containing the performance metrics for the data radio bearers, and provide the performance metrics to the application service indexed by the identification token.
  • the identification token is composed of one or more temporary identifiers used by the RAN nodes to manage a Radio Resource Control (RRC) connection of the UE.
  • RRC Radio Resource Control
  • the identification token is composed of one or more persistent UE identifiers assigned by the RAN to the UE.
  • the instructions that, when executed by the at least one processor, cause the RAN controller at least to send a request to a 5G core network for a mapping between the persistent UE identifiers and at least a UE NG Application Protocol (NGAP) identifier, serving cell identifier, and one or more data radio bearer identifiers, receive the UE NGAP identifier, the serving cell identifier, and the data radio bearer identifiers mapped to the persistent UE identifiers from the 5G core network, send a request to a RAN node, based on the serving cell identifier, for a mapping between the UE NGAP identifier and a Cell Radio Network Temporary Identifier (C-RNTI) granted to the UE, and receive the C- RNTI from the RAN node mapped to the UE NGAP identifier.
  • C-RNTI Cell Radio Network Temporary Identifier
  • FIG. 17 is a flow chart illustrating a method of performing a token refresh procedure in a UE in an illustrative embodiment.
  • FIG. 10 is a block diagram of application server 1000 in an illustrative embodiment.
  • Application server 1000 is equipment of an ASP 408 configured to provide an application service 410.
  • Application server 1000 may be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, as a virtualized function instantiated on an appropriate platform (e.g., a cloud infrastructure), etc.
  • application server 1000 includes the following subsystems: a network interface component 1002, an application controller 1004, a KPM collector 1006, and an adaptation manager 1008 that operate on one or more platforms.
  • Network interface component 1002 may comprise circuitry, logic, hardware, means, etc., configured to exchange control plane messages or signaling with other network elements or NFs.
  • Network interface component 1002 may operate using a variety of protocols or reference points.
  • Application controller 1004 may comprise circuitry, logic, hardware, means, etc., configured to provide functions, operations, or activities of the application service 410.
  • application controller 1004 may interact with an application client to establish an application service connection, receive data from an application client, send data to an application client, etc.
  • KPM collector 1006 may comprise circuitry, logic, hardware, means, etc., configured to collect KPM 702 for application service flows established for the application service 410.
  • Adaptation manager 1008 may comprise circuitry, logic, hardware, means, etc., configured to adapt the application service 410 based on RAN behavior, measurements (e.g., KPM), conditions, etc., and/or other inputs.
  • Application server 1000 may include various other components not specifically illustrated in FIG. 10.
  • FIG. 11 is a flow chart illustrating a method 1100 of providing application service adaptation in an application server in an illustrative embodiment. The steps of method 1100 in FIG. 11 will be described with reference to application server 1000 as in FIG. 10, but those skilled in the art will appreciate that method 1100 may be performed in other systems or network entities.
  • one assumption is that application controller 1004 (through network interface component 1002) interacts with application client 406 on UE 106 to establish an application service connection 510, and transmits data to or receives data from application client 406 in an application service flow 512.
  • the application service flow 512 may comprise streaming data, interactive data, etc.
  • KPM collector 1006 of application server 1000 receives the identification token 701 from UE 106 that identifies the DRB(s) 504 serving the application service flow 512 (step 1102), such as through network interface component 1002.
  • KPM collector 1006 sends a request to RAN controller 404 for KPM mapped to the application service flow 512 between application service 410 and application client 406 (step 1104), such as through network interface component 1002.
  • KPM collector 1006 also provides the identification token 701 to RAN controller 404 (step 1106), in the request or in another message.
  • KPM collector 1006 receives the KPM 702 from RAN controller 404 indexed by the identification token 701 (step 1108), such as through network interface component 1002.
  • KPM collector 1006 may receive a notify message from RAN controller 404, in response to a register request, containing the KPM 702 for the application service flow 512 and the identification token 701. The KPM are therefore mapped to the application service flow 512 based on the identification token 701.
  • Adaptation manager 1008 then adapts the application service 410 based on the KPM 702 (step 1110).
  • adaptation manager 1008 is able to adapt the application service 410 based on network conditions in RAN 102.
  • adaptation manager 1008 may adjust the amount of traffic application service 410 sends/receives through the network (i.e., adjust traffic of the application service flow 512 over DRB(s) 504)).
  • adaptation manager 1008 may send a request to RAN controller 404 for certain treatment for the application service flow 512.
  • One technical benefit is the application service 410 may be optimized or adjusted based on RAN conditions, such as to provide QoE optimization.
  • User interface component 1208 is a hardware component for interacting with an end user.
  • user interface component 1208 may include a display 1250, screen, touch screen, or the like (e.g., a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) display, etc.).

Abstract

L'invention concerne des systèmes, des procédés et un logiciel d'adaptation d'un service d'application. Selon un mode de réalisation, un contrôleur de réseau d'accès radio (RAN) (404) d'un RAN (102) est configuré pour fournir un service radio à un équipement utilisateur (UE) (106). Le contrôleur de RAN reçoit une demande d'un service d'application (410) de mesures de performance (702) d'un flux de service d'application (512) entre le service d'application et un client d'application hébergé par l'UE. Le contrôleur de RAN reçoit un jeton d'identification (701) en provenance du service d'application qui identifie une ou plusieurs porteuses radio de données (504) du RAN desservant le flux de service d'application, reçoit un message de rapport en provenance d'un ou de plusieurs nœuds de RAN (402) du RAN contenant les mesures de performance des porteuses radio de données, et fournit les mesures de performance au service d'application indexé par le jeton d'identification. Le service d'application peut ensuite être adapté sur la base des mesures de performance.
