Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a traffic charging method and an MME.
Background
In a non-independent Networking (NSA) architecture network of a fifth generation mobile communication (5th generation, 5G) to be deployed, according to the specification of the international standardization organization 3GPP, a Radio Access Network (RAN) may report a 5G service usage amount (secondary RAT usage data report) of a user to a core network side Mobile Management Entity (MME) in a specific scenario, and the MME sequentially forwards the 5G service usage amount to a Serving Gateway (SGW), and the SGW forwards the 5G service usage amount to a PGW, and the SGW or the PGW reports the service usage amount to a charging system, thereby completing a charging operation. However, in actual use, the flow triggering scenario of 5G usage reporting is very complicated, and there is periodic usage reporting, and if the usage reporting is processed according to the usage reporting flow specified in the relevant standard of the third generation partnership project (3 GPP), the network signaling overhead is huge, and the network burden is too heavy. In fact, this problem has appeared in the fourth generation mobile communication technology (4G) network deployment and has not been solved completely. The common practice of the 4G-era operator is to uniformly charge the user traffic in view of the second generation mobile phone communication technology (2G) and 3G traffic without distinguishing whether the user traffic is 4G traffic. Thus, 4G exclusive users and the usage thereof cannot be charged, and a plurality of network operation methods and means are missed. However, similar problems exist in the current 5G NSA network to be deployed, and if not solved, the 5G traffic can only be treated as 4G traffic, and the like.
In the existing network deployment, in order to avoid huge network signaling overhead and heavy network burden, when user flow is charged, the user flow type is not distinguished, a uniform charging mode is adopted, and the charging of a special flow user cannot be realized.

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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
It should be noted that, in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.
In the to-be-deployed 5G NSA architecture network, according to the rules of the international standardization organization 3GPP, the RAN may report the usage amount of the 5G service of the user to the core network side MME under a specific scenario, and the MME forwards the usage amount of the 5G service to the SGW in sequence, and the SGW forwards the usage amount to the PGW, and reports the usage amount to the charging system through the SGW or the PGW, thereby completing the charging operation. However, in actual use, the flow triggering scenario of 5G usage reporting is very complicated, and there is periodic usage reporting, and if the usage reporting flow specified in the 3GPP related standard is used for processing, the network signaling overhead is huge, and the network burden is too heavy. In fact, the problem has already occurred at the time of 4G network deployment and there is no perfect solution. The common practice of the 4G operator is to uniformly charge based on 2G and 3G traffic without distinguishing whether the user traffic is 4G traffic. Thus, 4G exclusive users and the usage thereof cannot be charged, and a plurality of network operation methods and means are missed. However, similar problems exist in the current 5G NSA network to be deployed, and if not solved, the 5G traffic can only be treated as 4G traffic, and the like. In the existing network deployment, in order to avoid huge network signaling overhead and heavy network burden, when user flow is charged, the user flow type is not distinguished, a uniform charging mode is adopted, and the charging of a special flow user cannot be realized.
Based on the above technical background and the problems existing in the prior art, referring to fig. 1, an embodiment of the present invention provides a traffic charging method. Namely, a regular service information reporting mechanism is formed by setting a service information reporting threshold and setting a buffer area (buffer) to store the service information which does not reach the preset threshold. The method comprises the following steps:
101. a mobile management entity MME receives the service information of the user reported by the wireless RAN and stores the service information of the user to a cache region; wherein the service information carries the access network type.
Illustratively, the traffic information includes, but is not limited to, at least one of: uplink consumption, downlink consumption, user scene, service duration and user dimension. The access network type may be any of the following: 5G, 4G, 3G and 2G.
In addition, the operator classifies its own users into general users (i.e. users that do not need to record their traffic specifically according to the type of access network (e.g. 5G network)) and specific users (i.e. users that need to record their traffic specifically according to the type of access network). The corresponding marking can be carried out by the MSISDN or IMSI of the user number, and the information of the two kinds of users is recorded in the database. For a common user, the generated 5G service information can be charged together with the 4G, 3G, 2G and other service information; for a specific user, the generated service information of 5G needs to be charged separately.
TABLE 1
In one implementation, taking the access network type as a 5G network as an example, a buffer (i.e., a cache region) is set on the MME. Without changing the scenario and flow mechanism for reporting 5G Usage in a 5G NSA network specified by 3GPP, in any triggering scenario, when the RAN on the wireless side reports 5G Usage to the MME, the MME reads the Usage information of "Usage Data DL (uplink Usage)" and "Usage Data UL (downlink Usage)" in the Secondary RAT Usage Data Report cell as shown in table 1, "EBI (evolved packet system bearer ID, evolved packet system bearer identifier)" information, "start timestamp)", and "end timestamp" time message, associates the EBI and the user identifier (such as IMSI) correspondingly, and performs cumulative statistics on all specific users attached to the MME. When the accumulated value of the service information (uplink and downlink usage and related information) of the user 5G does not exceed the set threshold, the MME only accumulates and caches the 5G uplink and downlink usage and related information (see table 1) of the user, and does not directly transmit the 5G uplink and downlink usage and related information to the SGW and the PGW for charging reporting; when the accumulated value of the user exceeds a threshold or the user is separated from the MME, the MME transmits the accumulated 5G uplink and downlink usage and related information of the user to the SGW and the PGW for charging by reporting, and meanwhile, clears the buffer of the user and carries out subsequent cache accumulation calculation. And if the buffer on the MME is about to overflow when 90 percent of the buffer on the MME reaches, the MME transmits the accumulated 5G uplink and downlink usage and related information of all the attached specific users on the equipment to the SGW and the PGW for charging by reporting, and simultaneously clears all the buffers and carries out subsequent cache accumulation calculation. The content of the Secondary RAT Usage Data Report cell in the 3GPP standard is shown in Table 1.
102. And the MME determines that the service information of the user in the cache region under the same access network type exceeds a preset threshold, and then sends the service information of the cache region to a charging system through gateway equipment so that the charging system can calculate the flow charge according to the service information of the user in the cache region under the same access network type.
In an implementation manner, the MME determines that the service information of the user in the cache region in the same access network type exceeds a preset threshold, and may send part or all of the service information of the cache region to the charging system through the gateway device according to actual needs. In addition, the MME may clear the service information that has been sent to the charging system in the cache.
Optionally, the service information includes an uplink usage amount, and the MME determines that the service information of the user in the same access network type in the cache region exceeds a preset threshold, specifically including: and the MME counts the uplink usage of the user in the cache region under the same access network type to generate statistical data of the uplink usage, and if the statistical data of the uplink usage is greater than the threshold of the uplink usage, the service information of the user in the cache region under the same access network type is determined to exceed the preset threshold.
For example, the threshold of the uplink usage amount of the user may be set to 10MB, and when the uplink usage amount of the user in the same access network type in the MME statistical buffer exceeds 10MB, it is determined that the service information of the user in the same access network type in the buffer exceeds the preset threshold.
Optionally, the service information includes downlink usage, and the MME determines that the service information of the user in the same access network type in the cache region exceeds a preset threshold, specifically including: and the MME counts the downlink usage of the user in the cache region under the same access network type to generate statistical data of the downlink usage, and if the statistical data of the downlink usage is greater than a threshold of the downlink usage, the service information of the user in the cache region under the same access network type is determined to exceed a preset threshold.
For example, the threshold of the downlink usage amount of the user may be set to 100MB, and when the downlink usage amount of the user in the same access network type in the MME statistical cache region exceeds 100MB, it is determined that the service information of the user in the same access network type in the cache region exceeds the preset threshold.
Optionally, the service information includes a scene where the user is located, and the MME determines that the service information of the user in the same access network type in the cache region exceeds a preset threshold, specifically including: and if the MME determines that the scene where the user in the cache region is under the same access network type does not belong to the scene threshold where the user is under, the MME determines that the service information of the user in the cache region under the same access network type exceeds the preset threshold.
For example, the location information (the scene where the user is located) reported by using scenes such as user attachment, Tracking Area Update (TAU), tracking area identifier (RAU), and the like, such as TAC, cell, and the like. When the user leaves a set geographic area (the scene threshold where the user is located), the geographic threshold is considered to be exceeded (the scene threshold where the user is located).
Optionally, the service information includes service duration, and the MME determines that the service information of the user in the same access network type in the cache region exceeds a preset threshold, specifically including: and the MME counts the service time of the user in the cache region under the same access network type to generate statistical data of the service time, and if the statistical data of the service time is greater than the threshold of the service time, the service information of the user in the cache region under the same access network type is determined to exceed the preset threshold.
For example, the calculation is performed by using "start timestamp" and "end timestamp" in table 1, and the single service duration is end timestamp-start timestamp ". And performing accumulated calculation on the service duration in the cache region by the service duration for multiple times. When the accumulated service duration of a certain user on the MME exceeds C, for example, 10 minutes, it is considered that the service duration exceeds the threshold.
In addition, the preset threshold may be set according to the uplink and downlink usage of the user dimension, the scene where the user is located, and the service duration, or may be set according to the uplink and downlink usage of the bearer (EBI) or session (session) dimension, the scene where the user is located, and the service duration.
In the method, MME firstly stores the service information of the user reported by the receiving wireless RAN to a buffer area; wherein the service information carries the type of the access network; and when the service information of the user in the cache region under the same access network type is determined to exceed the preset threshold, the service information of the cache region is sent to a charging system through gateway equipment, so that the charging system calculates the flow charge according to the service information of the user in the cache region under the same access network type. The invention can obtain the flow charge of the user in the same access network type by counting the flow generated by the service in the same access network type.
In the embodiment of the present invention, functional modules may be divided according to the method embodiment, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, the division of the modules in the embodiment of the present invention is schematic, and is only a logic function division, and there may be another division manner in actual implementation.

In an exemplary scheme, the processing unit 202 is specifically configured to count uplink usage of the user in the buffer area under the same access network type to generate statistical data of the uplink usage, and determine that service information of the user in the buffer area under the same access network type exceeds a preset threshold if the statistical data of the uplink usage is greater than a threshold of the uplink usage, where the service information includes the uplink usage.
In an exemplary scheme, the processing unit 202 is specifically configured to count downlink usage of users in a buffer area under the same access network type to generate statistical data of the downlink usage, and if the statistical data of the downlink usage is greater than a threshold of the downlink usage, it is determined that service information of users in the buffer area under the same access network type exceeds a preset threshold; wherein the service information includes downlink usage.
In an exemplary scheme, the processing unit 202 is specifically configured to determine that a scene where a user in the same access network type in the cache region is located does not belong to a scene threshold where the user is located, and then determine that service information of the user in the same access network type in the cache region exceeds a preset threshold; wherein the service information comprises the scene where the user is located.
In an exemplary scheme, the processing unit 202 is specifically configured to count service durations of users in a cache area in the same access network type to generate statistical data of the service durations, and determine that service information of the users in the cache area in the same access network type exceeds a preset threshold if the statistical data of the service durations is greater than a threshold of the service durations, where the service information includes the service durations.
