Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The terms first, second and the like in the description and in the claims of the present invention are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the invention may be practiced other than those illustrated or described herein, and that the objects identified as "first," "second," etc. are generally a class of objects and do not limit the number of objects, e.g., a first object may be one or more.
Aiming at the existing charging mode, the following problems also exist:
problem 1: when some more complex services (such as a power network) are opened, a more complex charging policy may be involved. For example, part of the traffic of the terminal may only require a conventional charging policy, but part of the traffic needs to be better served, such as deterministic transmission, computationally intensive guarantees, etc. At this time, a flexible charging mode is required to support real-time adjustment of the charging policy. However, the existing charging mode is difficult to satisfy the real-time adjustment of the charging policy.
Problem 2: the charging of the terminal flow depends on the public credibility of the operator and the flow filter (Traffic Filters) pre-configured by the operator, the user terminal is difficult to participate, and the capability of data-drive (data-drive) is not available, that is, the capability negotiated between the user and the operator is not provided in the current mechanism. For example, when a user temporarily has an important file to be transmitted, or an important conference to be participated, it is impossible to go to the operator on site to customize the relevant service and then access the service. The on-demand charging mode is predicted by operation Shang Hennan or configured in real time, and needs a more flexible activation mode and a charging mode.
In order to solve the problem that the existing charging mode is single and difficult to meet diversified requirements, the embodiment of the invention provides a charging method, which can initiate flow/duration/service charging by a terminal, namely, the terminal starts the charging of special flow, so that the terminal is supported to adjust a charging strategy in real time according to the service requirements, thereby realizing a flexible charging mode and meeting diversified requirements; furthermore, the terminal can be incorporated into the charging operation to realize the charging mode negotiated with the operator, so that the intelligence of the network service can be improved.
Optionally, the embodiment of the present invention may be applicable to some scenarios in which charging is relatively complex, including but not limited to a Mobile Edge Computing (MEC) scenario of a Mobile network. In the MEC scenario, separation of the user plane and the control plane can be supported, so that flexible deployment of the user plane is facilitated.
The following describes the charging method provided by the embodiment of the present invention in detail through a specific embodiment and an application scenario thereof with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a charging method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 1, the method includes the following steps:
step 11: and determining that the network access equipment supports the function of charging initiated by the terminal.
Optionally, the charging method in the embodiment of the present invention may be used in an Application-aware network (APN), and may adopt a network-based programmable charging mechanism. For network programmability, it means that besides the basic forwarding according to the destination address of the packet, the network device can flexibly support other operations, such as source routing, new protocol/field analysis, etc., so as to support the on-demand processing of data traffic and provide a simpler differentiated service mechanism. Through network programming, the terminal can put forward the demand of the self flow and start the charging of special flow. In one embodiment, the network programming involved in this embodiment is primarily SRv network programming in Segment Routing Header (SRH).
And under the function of initiating charging by the terminal, the terminal is allowed to carry out related charging function calling. In one embodiment, the function of initiating charging by the terminal may be SRv FUNCT.
Step 12: and sending the first message to the network access equipment.
In this embodiment, the first packet is used to start charging for a special flow. The network access device is, for example, a terminal egress gateway, which may also be referred to as a user egress gateway, an egress gateway, a charging gateway, or the like. In one embodiment, the network access device may be a charging gateway, that is, may be one of charging points of terminal traffic.
Optionally, in the service use process, the terminal may send the first packet. The first packet may be a data packet, that is, relevant information such as SRv FUNCT information is inserted into an original data packet to obtain the first packet, or a packet whose header is consistent with the data packet (for example, the packet includes the same source and destination addresses) may be separately constructed, and the constructed packet also includes SRv FUNCT information, but may not include a specific load. The first message may be sent at specific intervals, or may be sent on demand, and need not be sent all the time.
In the charging method of the embodiment of the invention, after the network access equipment determines to support the function of charging initiated by the terminal, the terminal can send the first message to the network access equipment, and the first message is used for starting charging of special flow. Therefore, the flow charging can be initiated by the terminal, so that the terminal is supported to adjust the charging strategy in real time according to the service requirement, a flexible charging mode is realized, and diversified requirements are met.
That is to say, the embodiment of the present invention extends the network programming capability in the data plane, for example, extends the SRv network programming charging, and can implement a more flexible charging manner compared with the charging manner in the existing control plane. Furthermore, the terminal is incorporated into the charging operation to realize the charging mode negotiated with the operator, so that the intelligence of the network service can be improved.
In this embodiment of the present invention, optionally, the first packet may include first traffic statistical information generated by the terminal, where the first traffic statistical information is used by the network access device to compare the first traffic statistical information with the second traffic statistical information, and when a deviation between the first traffic statistical information and the second traffic statistical information satisfies a preset condition (for example, is smaller than a preset threshold), it is determined that the first traffic statistical information is reasonable, or when a deviation between the first traffic statistical information and the second traffic statistical information does not satisfy the preset condition, it is determined that the first traffic statistical information is unreasonable. The second traffic statistics are generated by the network access device.
Then, if the network access device determines that the first traffic statistic information is reasonable, charging can be performed according to the first traffic statistic information. Or, if the network access device determines that the first traffic statistic information is not reasonable, the network access device may send alarm information to the terminal, even disconnect the service; the alarm information is used to indicate that the first traffic statistics generated by the terminal are not reasonable. Therefore, normal operation of the service can be ensured.
Optionally, the first traffic statistic information may be stored in a Segment Routing Header (SRH) of the first packet. For example, when calling SRv Function of the network access device that supports the statistical Function, the terminal may occupy the length of four SIDs in a Segment Identifier (SID) list of the SRH header, where the first SID is used to store SRv Function that supports the statistical Function, the second SID and the third SID are used to store signature information of the terminal, and the fourth SID is used to store the first traffic statistics information.
Optionally, in order to ensure the security of the information, the first traffic statistic information included in the first message may be encryption information. In addition, the first message may further include a terminal signature to verify the validity of the terminal.
In one embodiment, there is an encryption key between the terminal and the network access device. The terminal signs the first message by using the encryption key and encrypts the first traffic statistical information so as to protect the privacy of the user. After the network access equipment acquires the first message, the terminal identification is determined according to the terminal session to further determine the encryption key of the terminal, then the terminal signature is decrypted according to the encryption key to verify the legality of the terminal, and the first flow statistical information is decrypted under the condition of verifying the legality, so that whether the first flow statistical information is reasonable or not is determined.
In the embodiment of the invention, the terminal can receive the function information of the network access equipment before determining that the network access equipment supports the function of charging initiated by the terminal, and then can determine that the network access equipment supports the function of charging initiated by the terminal according to the function information. Optionally, the function information may be sent by a network access device, such as a terminal egress gateway, or may be sent by some server, such as a Dynamic Host Configuration Protocol (DHCP) server, which is not limited herein. For example, taking SRv FUNCT as an example, the terminal egress gateway may send relevant SRv FUNCT information to the terminal to allow the terminal to make the relevant charging function call.
Optionally, the Function information may be SRv6Function of the network access device, where the Function information supports a statistical Function; the Function information may include a LOC (location) field, a FUNCT (Function) field, and an ARGS (parameter) field, where the LOC field is used to route and forward a packet to the network access device, the FUNCT field is used to point to SRv Function supporting a statistical Function, and the ARGS field is used to point to a specific statistical type.
Optionally, the receiving the function information of the network access device may be: the terminal receives the function information of the network access equipment through an extension option field of a dynamic host configuration protocol DHCP.
Referring to fig. 2, fig. 2 is a flowchart of a charging method according to an embodiment of the present invention, where the method is applied to a network access device, such as a terminal egress gateway, and the terminal egress gateway may also be referred to as a user egress gateway, an egress gateway, a charging gateway, and the like. As shown in fig. 2, the method comprises the steps of:
step 21: and receiving a first message sent by a terminal.
In this embodiment, the first message is used to start charging for a special flow. The network access device may be a charging gateway, i.e. may be one of the charging points for terminal traffic.
Optionally, in the service use process, the terminal may send the first packet. The first packet may be a data packet, that is, relevant information such as SRv FUNCT information is inserted into an original data packet to obtain the first packet, or a packet whose header is consistent with the data packet (for example, the packet includes the same source and destination addresses) may be separately constructed, and the constructed packet also includes SRv FUNCT information, but may not include a specific load. The first message may be sent at specific intervals, or may be sent on demand, and need not be sent all the time.
In the charging method of the embodiment of the invention, the terminal can initiate flow charging, thereby supporting the terminal to adjust the charging strategy in real time according to the service requirement, realizing a flexible charging mode and meeting diversified requirements.
In this embodiment of the present invention, optionally, the first packet includes first traffic statistical information generated by the terminal; after receiving the first message sent by the terminal, the method further includes:
comparing the first traffic statistic with a second traffic statistic; wherein the second traffic statistics are generated by a network access device;
determining that the first flow statistic information is reasonable under the condition that the deviation between the first flow statistic information and the second flow statistic information meets a preset condition;
and charging according to the first flow statistical information.
Optionally, after comparing the first traffic statistic with the second traffic statistic, the method further includes:
determining that the first flow statistical information is unreasonable under the condition that the deviation between the first flow statistical information and the second flow statistical information does not meet a preset condition;
sending alarm information to the terminal; wherein the alarm information is used for indicating that the first traffic statistic information is unreasonable. Therefore, normal operation of the business service can be ensured.
Optionally, the first message further includes a terminal signature, and before comparing the first traffic statistical information with the second traffic statistical information, the network access device may further determine a type of the first traffic statistical information, for example, a duration or a traffic, and determine validity of the terminal according to the terminal signature. In one embodiment, the network access device may determine the type of the first traffic statistic information according to parameter information in the first message.
The following describes the specific example of the present invention in detail with reference to fig. 3, taking a charging process based on SRv6 network programming as an example.
In the specific example of the present invention, a network access device such as an egress gateway may send relevant SRv FUNCT information to a terminal such as a client, allowing a user to perform relevant charging function call. This related SRv FUNCT, end.acc, as described later, is a variant of the END function of SRv. The SID of a node in SRv, also called a FUNCT, typically includes a LOC (location): the FUNCT field, for a total of 128bits, specific LOC and FUNCT field lengths are preconfigured, e.g., 64bits for LOC field length and 64bits for FUNCT field length.
Optionally, the FUNCT part may further include an ARGS (parameters) field, in this case, the SID format of SRv is LOC: FUNCT: ARGS, wherein the lengths of the FUNCT field and the ARGS field also need to be configured in advance, and the node using this function needs to know the related length information. In a SRv network, these SIDs are typically distributed via protocols such as IGP/BGP for network node programming. However, the client concerned in the present application is not a network node but a terminal node, and does not run the IGP/BGP network protocol, so if the client wants to invoke the capability of the network node, the client may send the FUNCT of the gateway to the client through some other means, and then perform simpler network programming by the client, and the reason that the client can only support the simpler network programming is that the client can know less network information.
Optionally, the terminal may receive SRv SID, that is, the above-mentioned SRv FUNCT, through the DHCPv6 message. The DHCP server may issue the relevant charging SRv Function to the terminal through the DHCPv6, and in one possibility, the DHCP server is the charging point, i.e., the egress gateway of the terminal traffic, or the DHCP server knows the charging point/egress gateway information of the terminal and knows the SID used for charging, so as to send the relevant information to the terminal.
In the specific example of the present invention, for some temporary flows with special requirements, the terminal may propose related service requirements to the network through the mechanism of the APN. For example, it is possible to let the network better provide services on demand by carrying traffic demands in the packet packets, e.g. entering different tunnel or SR policies on the network side. As shown in fig. 3, the corresponding charging process may include:
step 31: the terminal and the exit gateway (authentication point access device) complete authentication and authorization.
Step 32: and the terminal and the exit gateway finish the DHCP address allocation.
Step 33: the egress gateway and the authentication server initiate a charging process, for example, the egress gateway sends a charging-Start Request (Accounting-Request Start) to the authentication server and receives a charging-Response (Accounting-Response) fed back by the authentication service.
Step 34: the terminal accesses the Internet network.
Step 35: the terminal needs to access a special service, such as an MEC service.
Step 36: the terminal starts a special Service through an APN message, and the APN message can carry a terminal identification ID, service Level Agreement (SLA) information and the like.
Step 37: the terminal starts information statistics of special services, such as starting statistics of special traffic, through a specific FUNCT of SRv of the egress gateway, and adds the information into a message as required to send the message to the egress gateway, such as sending an APN message, which at least includes flow ID, charging statistical information, and the like.
Optionally, the sent message needs to include a related signature, encrypted charging information, and the like.
Alternatively, the FUNCT need not be inserted into the data packet of each flow, and may be sent at a specific time interval, or sent on demand. Specifically, the SRH header containing the FUNCT of SRv may be inserted into a data packet, or a packet whose header is identical to the data packet and does not contain a specific payload may be separately constructed.
Step 38: and the exit gateway carries out charging according to the terminal identification and the identification Flow ID of the user Flow. If the received message contains the flow statistic information (SRv 6 Accounting function of the gateway is contained in the message), the message is forwarded normally, and the relevant information is recorded for processing.
Optionally, the terminal identifier may be an IP address of the terminal, or other identifiers.
Optionally, the Flow ID may be carried in an APN encapsulation, or may be carried in another location of the IPv6 message. The Flow ID may be encapsulated in a format specified in the APN, or may reuse, for example, the Flow label field of IPv 6.
Optionally, the Flow ID may also be selected as other content, such as a five-tuple of the terminal traffic, such as a source address, a destination address, a source port, a destination port, and a protocol type.
Optionally, SRv6 Accounting FUNCT may record the message information of the terminal, for example: 1) The gateway determines a terminal identifier according to the terminal session, so as to further determine a secret key of the terminal; 2) The gateway decrypts the signature of the terminal and verifies the validity of the terminal; 3) The gateway decrypts the flow statistic information of the terminal, compares the flow statistic information with the flow statistic information of the gateway, and determines that the flow statistic information is reasonable and charges if the deviation is within a certain reasonable range; and if the deviation exceeds a certain reasonable range, starting a flow capturing function, and alarming the terminal, even cutting off the service.
Step 39: and the gateway feeds back the information.
Optionally, if it is determined that the traffic statistics of the terminal is reasonable or unreasonable, the gateway may notify the terminal through some way. For example, an IPv6 packet sent to the terminal may be constructed, which does not contain actual user data information, but contains some TLV information in the header (e.g. in options of DOH or in payload) to inform about whether the traffic statistics is reasonable or unreasonable. Or some TLV information may be inserted into the message of the terminal, and then the message arrives at the server, and the server inserts the relevant information into a feedback message of the stream, and the inserted position may also be in options of DOH.
In the embodiment of the present invention, the SRv6 Accounting FUNCT may have the following characteristics:
1) Between the terminal and the gateway there may be a key for signing. The terminal uses this key to sign the message content and encrypt the billing information (protecting the user's privacy). The gateway uses this key to identify the relevant terminal and decrypt the relevant information.
2) Through some mechanisms, such as Domain Name System (DNS), DHCP, or Stateless Address Auto Configuration (SLAAC), the gateway may send SRv FUNCT to the terminal, allowing the user to make a call to the related charging function.
3) The SRv Accounting FUNCT in the message sent by the terminal can be stripped off at the gateway, for example, inserted as a separate SRH header.
For example, the format of SRv Accounting FUNCT may include at least encrypted traffic statistics, signatures (e.g., the first 128bits of a 256-bit signature), signature cont. (other part storing signatures), and SRv Accounting FUNCT (ARGs), as shown in fig. 4. For example, SRv6 Accounting function is A1::00AC 0001, A1 is the address of the gateway, 00AC is the function, and 0001 is the parameter, representing statistics according to the flow. The signature occupies two SRv SID spaces, and the encrypted traffic information occupies one SRv SID space.
Note that this FUNCT follows LOC of SRv: FUNCT: format of ARGS, can be referred to as end. The feature of this function is for charging and three 128bits SIDs followed by it is the information provided for this function, e.g. from the terminal client to the "charging point". The order of the SID in fig. 4 is reverse, mainly because in the SRH header of IPv6, the SID list is reverse, and needs to be processed by a SL (Segment Left) pointer before and after.
For example, the source and destination addresses of the terminal accessing the server are < E:, D:, and the charging SRH header is inserted, which can be changed into < E:, A1::00AC 0001> < D:, statistical information, signature information (cont), A1::00AC 0001, SL =4>.
For another example, assuming that a message without inserting end.acc into the client is < E:, D: >, and the inserted message is < E:, A1:: 00ac.
In one embodiment, when issuing the relevant charging SRv Function information Function to the terminal through the DHCPv6, a new Option field Option, for example 200, of the DHCPv6 may be applied, which is specifically used for SIDs carrying gateways. Acc type in this embodiment may be set to 100, and it is assumed that the option _ gateway _ SID may optionally carry SRv SID, which is only one of them.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a charging apparatus according to an embodiment of the present invention, where the charging apparatus is applied to a terminal, and as shown in fig. 5, the charging apparatus 50 may include:
a first determining module 51, configured to determine that the network access device supports a function of initiating charging by a terminal;
