Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The information processing method in this embodiment is applicable to a network device in a 5G system or a New wireless (NR) system architecture.
The embodiment of the invention provides an information processing method. FIG. 1 is a first flowchart illustrating an information processing method according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: the core network side equipment sends service requirement information and first indication information to the access network equipment through the first core network equipment; the first indication information is used for indicating that the resources of the access network equipment can not meet the service requirement information and feeding back the information;
step 102: and the core network side equipment receives second indication information from the access network equipment, wherein the second indication information is used for indicating that the resources of the access network equipment cannot meet the service requirement information.
In this embodiment, the core network side device may be an AF in a 5G system or an NR system; the Access Network device may be a Radio Access Network (RAN) device in a 5G system or an NR system, such as a base station.
In this embodiment, a core network side device sends service requirement information and first indication information to an access network device through a plurality of core network devices; the plurality of core network devices are core network devices which need to pass through the service requirement information and the first indication information transmission path of the access network device and the core network side device. Optionally, the plurality of core network devices may include the following core network devices: an Access Management Function (AMF), a Session Management Function (SMF), a Policy Control Function (PCF), a Network open Function (NEF), and the like. The first core network device in this embodiment may specifically be one of the core network devices. For example, the first core network device may be an SMF.
In this embodiment, in the process of establishing a Protocol Data Unit (PDU) session, the core network side device in this embodiment may send the service requirement information and the first indication information to the access network device through an existing message.
Illustratively, the core network side device may carry the service requirement information and the first indication information through a message in a PDU session establishment process.
In this embodiment, the service demand information at least includes a lifetime (survival time) parameter; alternatively, the message may include a time-to-live field for carrying the service requirement information. Illustratively, the time-to-live (survival time) parameter may represent a quality of service parameter that can be reached by monitoring packets to determine that the transmission of the packets can meet the quality of service requirement. For example, a time to live (survival time) parameter may be a threshold for a parameter that, if monitored, may indicate that the quality of service requirement is not met.
Optionally, the service requirement information at least includes a survival time, a maximum number of continuously transmitted packets lost, or a tolerable degree of packet loss; in other words, the time-to-live parameter or time-to-live field may include at least time-to-live, maximum number of consecutive transmission packets lost, or packet loss tolerance. Wherein the time-to-live indicates a time duration of the time-to-live.
For example, taking core Network side equipment as an AF for example, in a PDU session establishment process, after receiving a policy authentication notification (Npcf _ policy authorization _ notification) message of a PCF, the AF may send a policy authentication authorization notification Response (Npcf _ policy authorization _ notification _ Response) message to the PCF, where the policy authentication notification Response message may include a Time Sensitive Network (TSN) Quality of Service (QoS) container (container) parameter, the TSN QoS container parameter includes Service requirement information and first indication information, and the first indication information is used to indicate that the access Network equipment performs feedback when resources cannot meet the Service requirement information. Further, after receiving the policy authentication notification Response (Npcf _ policy authorization _ Notify _ Response) message, the PCF further sends a message to other core network devices, where the message carries a TSN QoS container parameter, and the TSN QoS container parameter includes service requirement information and/or first indication information, so that the access network device receives the service requirement information and/or the first indication information.
In some optional embodiments, the first indication information may be implemented by a lifetime time notification control (survival time notification control). For example, the survival time notification control may be represented by a specific indicator or a specific field in the message. For example, if the value of the specific indication bit or the specific field is 1, the specific indication bit or the specific field may be used to indicate the first indication information; correspondingly, if the specific indication bit or the specific field is empty or takes other values, it indicates that the message includes the first indication information.
In some optional embodiments of the present invention, the core network side device supports aggregating a plurality of service flows; each service flow corresponds to a survival time or the maximum continuous transmission packet loss number. Optionally, the method further comprises: the core network side equipment aggregates a plurality of service flows when determining that the service flows support aggregation based on the characteristic information of each service flow; wherein the characteristic information includes at least one of: survival time, maximum continuous transmission packet loss number, packet loss tolerance, periodicity, traffic class, egress port, and burst arrival time; correspondingly, the core network side device selects the minimum value of the survival time, the minimum value of the maximum continuous transmission packet loss number or the minimum value of the packet loss tolerance degree corresponding to the plurality of service flows as the service demand information corresponding to the aggregated service flow.
It can be understood that, in the scenario of aggregating multiple service flows in this embodiment, the AF may select, from multiple survival times or multiple maximum consecutive transmission packet loss numbers or multiple packet loss tolerance degrees corresponding to the multiple service flows, a minimum value of the survival time or a minimum value of the maximum consecutive transmission packet loss number or a minimum value of the multiple packet loss tolerance degrees as the service demand information corresponding to the aggregated service flow. If some service flows do not have the service requirement information such as the time to live or the maximum continuous transmission packet loss number or the packet loss tolerance, the AF will not aggregate the service flows without the service requirement information and the service flows with the service requirement information.
In this embodiment, when the resource of the access network device cannot meet the service requirement information, the access network device sends second indication information to the core network side device, where the second indication information is used to indicate that the resource of the access network device cannot meet the service requirement information. For example, the access network device may carry the second indication information through a message, and the message may reach the core network side device through core network devices such as an AMF and an SMF. For example, the second indication information may be represented by a specific indication bit or a specific field in the message. For example, if the value of the specific indicator bit or the specific field is 1, the second indication information may be represented, that is, the resource of the access network device may not meet the service requirement information. In yet another example, the second indication information may also be represented by a specific type of message.
Based on the foregoing embodiment, the embodiment of the present invention further provides an information processing method. FIG. 2 is a second flowchart illustrating an information processing method according to an embodiment of the present invention; as shown in fig. 2, the method includes:
step 201: the access network equipment receives service requirement information and first indication information from core network side equipment; the first indication information is used for indicating the access network equipment to feed back the first message under the condition that resources cannot meet the service requirement information;
step 202: the access network equipment sends second indication information to the core network side equipment under the condition that resources cannot meet the service requirement information; the second indication information is used for indicating that the resources of the access network equipment cannot meet the service requirement information.
In this embodiment, the core network side device may be an AF in a 5G system or an NR system; the access network device may be a RAN device, such as a base station or the like, in a 5G system or an NR system.
In some optional embodiments of the present invention, the access network device receives, via a plurality of core network devices, service requirement information and first indication information sent by a core network side device; the plurality of core network devices are core network devices which need to pass through the service requirement information and the first indication information transmission path of the access network device and the core network side device. Optionally, the plurality of core network devices may include the following core network devices: AMF, SMF, PCF, NEF, etc.
In this embodiment, in the PDU session establishment process, the access network device in this embodiment may receive the service requirement information and the first indication information sent by the core network side device through an existing message. Illustratively, the service requirement information and the first indication information may be carried by a message in a PDU session establishment process.
In this embodiment, the service requirement information at least includes a survival time, a maximum number of continuously transmitted packets lost, or a tolerable degree of packet loss; wherein the time-to-live indicates a time duration of the time-to-live.
Exemplarily, taking a core network side device as an AF for example, in the PDU session establishment process, the AF sends a policy authentication notification Response (Npcf _ policy authorization _ Notify _ Response) message to the PCF; the policy authentication notification response message may include a TSN QoS container parameter, where the TSN QoS container parameter includes service demand information and first indication information, and the first indication information is used to indicate that the access network device performs feedback on the first message when resources cannot meet the service demand information. Further, after receiving the policy authentication notification Response (Npcf _ policy authorization _ Notify _ Response) message, the PCF further sends a message to other core network devices, where the message carries a TSN QoS container parameter, and the TSN QoS container parameter includes service demand information and/or first indication information, until the message received by the AMF includes a TSN QoS container parameter, and the TSN QoS container parameter includes the service demand information and/or the first indication information; the AMF sends a message to the access network equipment, wherein the message comprises a TSN QoS container parameter, and the TSN QoS container parameter comprises service demand information and/or first indication information.
In this embodiment, when the resources of the access network device cannot meet the service requirement information, for example, the resources of the access network device cannot meet the lifetime, the access network device sends second indication information to the core network side device through a message based on the first indication information; illustratively, the message may be an N2 message. The message may reach the core network side device via a second core network device such as an AMF, an SMF, etc.
By adopting the technical scheme of the embodiment of the invention, the access network equipment informs the core network side equipment in a feedback notification mode under the condition that the service requirement information cannot be met (namely the service quality requirement cannot be guaranteed), so that the core network side equipment can adjust the subsequent processing.
Based on the foregoing embodiment, an embodiment of the present invention further provides an information processing method, where the information processing method is applied to a first core network device, and in some examples, the first core network device may be an SMF, but of course, in this embodiment, the first core network device is not limited to being an SMF, and may also be another core network device. FIG. 3 is a third schematic flowchart of an information processing method according to an embodiment of the present invention; as shown in fig. 3, the method includes:
step 301: the first core network equipment receives service requirement information and first indication information from core network side equipment;
step 302: the first core network device sends the service requirement information and/or the first indication information to an access network device; the first indication information is used for indicating the access network equipment to feed back when the resources can not meet the service requirement information.
Optionally, the service requirement information at least includes a survival time, a maximum number of continuously transmitted packets lost, or a tolerable degree of packet loss; wherein the time-to-live indicates a time duration of the time-to-live.
In some optional embodiments of the present invention, the sending, to an access network device, the service requirement information and/or the first indication information includes: determining information content to be sent to the access network equipment based on the strategy information; the information content includes the service requirement information and/or the first indication information, and the service requirement information and/or the first indication information are sent to the access network equipment.
In this embodiment, the first core network device (e.g., SMF) obtains policy information in advance, where the policy information may include subscription information of a user or control policy of a service package. The first core network device determines the information content sent to the access network device according to the policy information. For example, the first core network device may send the first indication information only to the access network device; or sending the service requirement information and the first indication information to the access network equipment; or the access network equipment sends the service requirement information.
In some optional embodiments, in a case that the information content does not include the first indication information, the method further comprises: the first core network device sends third indication information to the core network side device; the third indication information is used for indicating that the access network equipment does not perform feedback for the service demand information.
It can be understood that, under the condition that the information content sent by the first core network device to the access network device does not include the first indication information, that is, the access network device does not need to continue to feed back the information on whether the service requirement information is satisfied, the first core network device sends the third indication information to the core network side device to inform the core network side device that the access network device does not feed back the information on the service requirement.
The information processing method according to the embodiment of the present invention is described below with reference to specific examples.
FIG. 4 is a first schematic interaction flow chart of an information processing method according to an embodiment of the present invention; as shown in fig. 4, the method includes:
step 400: step 1 to step 10b in the normal PDU conversation establishing process; i.e., from the UE initiating a PDU session setup request, to the SMF sending an N4 session setup/modify request to the UPF, and the UPF sending an N4 session setup/modify response to the SMF.
Step 401: the SMF sends a Session Management (SM) policy control Update Request (Npcf _ SMPolicyControl _ Update _ Request) message to the PCF.
Step 402: the PCF notifies (Npcf _ policy authorization _ Notify) the AF policy authentication message including parameters such as 5GS Bridge information and port management information container.
Step 403: AF sends strategy authentication notification Response (Npcf _ PolicyAuthority _ Notify _ Response) message to PCF, which carries information sent to PCF, including MAC address of DS-TT port and TSN QoS container; wherein the TSN QoS container will contain the Survival time and the Survival time notification control (i.e. the first indication information in the foregoing embodiment).
In some examples, aggregation of multiple traffic flows is supported at the AF; under the condition that each service flow corresponds to one survival time, the maximum continuous transmission packet loss number or the packet loss tolerance, selecting the minimum value of the survival time, the minimum value of the maximum continuous transmission packet loss number or the minimum value of the packet loss tolerance from a plurality of survival times, a plurality of maximum continuous transmission packet loss numbers or a plurality of packet loss tolerances corresponding to the service flows to be aggregated by the AF, and taking the minimum value as the service requirement information corresponding to the aggregated service flows; the total time contained in the TSN QoS container in the policy authentication notification Response (Npcf _ policyauthorization _ Notify _ Response) message and the subsequent SM policy control Update Response (Npcf _ SMPolicyControl _ Update _ Response) message, the Communication _ N1N2message transmission (Namf _ Communication _ N1N2MessageTransfer) message, and the PDU session resource establishment request message is the minimum value of the above-mentioned lifetime or the maximum number of consecutive transmission lost packets.
Step 404 to step 406: the PCF sends the tsnqqos container containing the survival time and the survival time notification control (i.e. the first indication information in the foregoing embodiment) sent by the AF to a 5G access network (NG-RAN) device through the SMF and the AMF; wherein, PCF sends SM strategy control Update Response (Npcf _ SMPolicyControl _ Update _ Response) message to SMF; the SMF sends a Communication _ N1N2message transfer (Namf _ Communication _ N1N2MessageTransfer) message to the AMF; the AMF sends a PDU Session Resource Setup Request (PDU Session Resource Setup Request) to the NG-RAN equipment; through the above message, the TSN QoS container containing the survival time and the survival time notification control (i.e., the first indication information in the foregoing embodiment) is transmitted to the NG-RAN device.
In some examples, the SMF may determine information content to send to the NG-RAN device based on the policy information; the information content comprises a Survival time and/or a Survival time notification control; if the information content does not include the survival time notification control, the SMF further needs to send an indication message (i.e., the third indication message in the foregoing embodiment) to the AF, so as to indicate that the access network device does not perform feedback for the service requirement information.
Further, step 407: the NG-RAN equipment sends a PDU Session Resource Setup Response (PDU Session Resource Setup Response) message to the AMF; step 408: the AMF sends a PDU Session Establishment Accept (PDU Session Establishment Accept) to the UE.
FIG. 5 is a schematic diagram illustrating an interaction flow of an information processing method according to an embodiment of the present invention; as shown in fig. 5, the method includes:
step 500: the RAN device determines a demand that cannot guarantee a lifetime (survival time) according to its own resources, and executes a subsequent process.
Step 501: the RAN device sends an N2message (N2 message) to the AMF, where the N2message includes a survival time notification control parameter (i.e., the second indication information in the foregoing embodiment).
Step 502: the AMF sends a PDU session update SM context (Namf _ PDU _ update smcontext) message to the SMF, where the message includes a survival time notification control parameter (i.e., the second indication information in the foregoing embodiment).
One implementation is: step 503 a-step 503 b: the SMF transmits a survival time notification control parameter (i.e., the second indication information in the foregoing embodiment) to the NEF by calling an event open notification (Nsmf _ EventExposure _ Notify) message; the NEF transmits the survival time notification control parameter (i.e., the second indication information in the foregoing embodiment) to the AF by calling a traffic impact notification (Nnef _ trafficlnfluency _ Notify) message.
Another implementation is that in step 503 c: the SMF directly transmits the survival time notification control parameter (i.e., the second indication information in the foregoing embodiment) to the AF by calling an event open notification (Nsmf _ EventExposure _ Notify) message.
Step 504: the AF adjusts the existing mechanism according to its own circumstances, and how to perform setting depending on the AF. For example, for AF in the field of car networking, it is a grade that the automatic price is lowered. And the AF in the audio and video field can reduce the adjustment modes such as the code rate of the uncompressed video stream and the like.
