Description

Monitoring event reporting method and device

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for reporting a monitoring event.

Background

The third generation partnership project (3 GPP) defines a Service Capability Exposure (SCE) architecture that can be applied to 4G and 5G networks, based on which the 3GPP network can securely provide core network service capabilities to a service server, such as monitoring individual terminals or groups of terminals according to requests of the service server.

For example, the SCE architecture applied to the 5G network may include an access and mobility management function (AMF) element and a network open function (NEF) element. The AMF network element can monitor the terminal, report the monitoring event generated by the terminal to the NEF network element through the monitoring event report, and send the monitoring event report of the terminal by the NEF network element according to the target address specified by the service server. In an existing event reporting scheme, when a NEF network element monitors a terminal group, all monitoring event reports corresponding to terminals in the terminal group received within a group reporting guard time are reported to a target address according to a preset group reporting guard time (group reporting guard time).

Since a terminal group may include a large number of terminals, and any terminal may have multiple monitoring event reports within the group reporting guard time, the open-function network element needs to report a large number of monitoring event reports to the target address, thereby consuming a large amount of network resources.

Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings.

The SCE architecture is a system architecture applied to a 3GPP network, and can support an event monitoring (event monitoring) request of a service server for a terminal or a terminal group, for example, loss of connection (loss of connectivity) monitoring, UE reachability (accessibility) monitoring, location reporting (location reporting) monitoring, roaming status (roaming status) monitoring, and the like.

FIG. 1 is a schematic diagram of an SCE architecture. As shown in fig. 1, the SCE architecture mainly includes an open-function network element and a plurality of monitoring network elements (monitoring network element 1, monitoring network elements 2, … …, and monitoring network element N). The monitoring network element is used for monitoring the terminal, generating a monitoring event report according to the monitored monitoring event of the terminal and reporting the monitoring event report to the open function network element. In a 4G network, the monitoring network element may be a Home Subscriber Server (HSS), or a Mobility Management Entity (MME), or a Serving GPRS Support Node (SGSN), and in a 5G network, the monitoring network element may be a unified data management element (UDM), or an access and mobility management function (AMF), and in future communications such as 6G communications, the monitoring network element may still be a UDM network element or an AMF network element, or may have other names, which are not limited in this application.

The open function network element is configured to aggregate monitoring event reports for different terminals, which are reported by multiple monitoring network elements, and report the aggregated monitoring event reports to a destination address (identified destination) provided by the service server. In a 4G network, the open function network element may be a service capability open function (SCEF) network, in a 5G network, the open function network element may be a network open function (NEF) network, and in future communication such as 6G communication, the open function network element may still be an NEF network element or have another name, which is not limited in this application.

The service server can request the open function network element to monitor the terminal or the terminal group according to the service requirement, and report the monitoring event report of the terminal or the terminal group to the target address. The target address may be an address of the service server, an address of another server, or an address of another network element in the 3GPP network. The target address may determine a terminal state according to the monitoring event report of the terminal or the terminal group, thereby providing a service to the terminal. In a 4G network, the service server may be a service capability server/application server (SCS/AS), and in a 5G network, an Application Function (AF). In the 6G communication, the service server may still be an AF or have another name, which is not limited in this application.

It is understood that the above functions may be either network elements in a hardware device, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (e.g., a cloud platform).

Based on the SCE architecture shown in fig. 1, monitoring of a single terminal or a group of terminals can be achieved. When the SCE architecture shown in fig. 1 is applied to monitoring a terminal Group, a Group reporting guard time (Group reporting guard time) is generally preset in an open functional network element, and a time length of the Group reporting guard time may be configured by a service server that requests to monitor the terminal Group. The open function network element may report, to the target address, the monitoring event report of the terminal in the terminal group received within the group reporting guard time according to the group reporting guard time interval.

In the embodiment of the application, the terminal is a device with a wireless communication function, and can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc.; but also various forms of User Equipment (UE), Mobile Station (MS), and terminal equipment (terminal device).

In this embodiment, the terminal group includes a plurality of terminals, the service server may request monitoring of all terminals in the terminal group through the terminal group identifier, and when reporting the monitoring event report of the terminal group to the target address, the open function network element may report the monitoring event reports of the plurality of terminals in the terminal group to the target address in a unified manner by using the terminal group as a unit. In one embodiment of a terminal group, the terminal may be a UE, and the terminal group may be a group of UEs (a group of UEs).

Based on the SCE architecture shown in fig. 1, each network element in the architecture can monitor the terminal group by the method shown in fig. 2. Fig. 2 is a schematic view of a terminal group monitoring process provided in an embodiment of the present application, as shown in fig. 2, which mainly includes the following steps:

s201: and the monitoring network element monitors the terminal according to the monitoring request of the service server.

The service server may send a monitoring request to the open function network element, where the monitoring request may include a monitoring type (monitoring type), a terminal group identifier (such as an external group identifier (external group ID)), and a target address, and the monitoring request may further include monitoring parameters such as a group reporting guard time, a maximum reporting number, a monitoring duration, and the like. The open-function network element can analyze the monitoring request, acquire and store a plurality of monitoring parameters in the monitoring request, and send part of the acquired monitoring parameters (such as monitoring parameters of monitoring type, external group identification, maximum reporting times, monitoring duration and the like) to the monitoring network element, so that the monitoring network element can monitor the terminal according to the monitoring request of the service server.

Specifically, in this embodiment, the terminal may be a terminal in a terminal group. The open function network element may first send a part of the monitoring parameters obtained according to the monitoring request to an HSS network element in the 4G network or an UDM network element in the 5G network, where the HSS network element or the UDM network element may determine each terminal included in the terminal group according to the terminal group identifier, and monitor each terminal in the terminal group according to the monitoring parameters provided by the open function network element, or allocate each terminal in the determined terminal group to another monitoring network element, that is, send the terminal identifier of one or more terminals in the terminal group and the monitoring parameters provided by the open function network element to the other monitoring network element, so that the other monitoring network element may monitor one or more terminals in the terminal group respectively according to the monitoring parameters provided by the open function network element.

S202: and when the terminal generates a monitoring event, the monitoring network element generates and sends a monitoring event report of the terminal to the open function network element.

The specific form of the monitoring event is determined according to the monitoring request of the service server, for example, the service server requests to monitor the terminal position in the terminal group, and the monitoring event refers to a change of the terminal position, and for example, the service server requests to monitor the terminal roaming state in the terminal group, and the monitoring event refers to a change of the terminal roaming state.

When the monitoring network element sends the terminal monitoring event report to the open-function network element, the monitoring network element may also send the identification information of the terminal (such as a mobile subscriber integrated services digital network number (MSISDN)) to the open-function network element at the same time, so that the open-function network element may determine the correspondence between the monitoring event report and the terminal according to the identification information of the terminal.

S203: and the open function network element converges the monitoring event reports of the terminals in the terminal group.

Specifically, a plurality of terminals in the terminal group may be monitored by different monitoring network elements, and therefore, for one terminal group, the open-function network element receives monitoring event reports corresponding to different terminals in the terminal group from the plurality of monitoring network elements. The open function network element converges the monitoring event reports from the plurality of monitoring network elements, thereby obtaining the monitoring event reports corresponding to each terminal in the terminal group.

S204: and the open function network element sends a monitoring event report of the terminal group to the target address.

When the group reporting guard time is preset in the open-function network element, the open-function network element may send the monitoring event report of the terminal group to the target address according to the group reporting guard time interval, that is, send the monitoring event report corresponding to one or more terminals in the terminal group to the target address. In an existing technical solution, a monitoring event report of a terminal group includes all monitoring event reports corresponding to one or more terminals in the terminal group received by an open function network element in group reporting guard time.

For example, referring to fig. 3, the group a includes a terminal 1, a terminal 2, a terminal 3, a terminal 4, and a terminal 5. Within the group reporting guard time, the open function network elements receive the monitoring event reports as shown in fig. 3, respectively. Based on the existing technical solution, the network element with open function will send all the monitoring event reports corresponding to the terminal 1, the terminal 2, the terminal 3 and the terminal 4 to the target address.

When reporting the monitoring event report of the terminal group to the target address, the open function network element consumes a large amount of network resources. Based on this, an embodiment of the present application provides a monitoring event reporting method, which is applied to an open function network element in an SCE framework, so as to reduce network resources required by the open function network element to report a monitoring event report to a target address.

Fig. 4 is a schematic flow chart of a monitoring event reporting method according to an embodiment of the present application, and as shown in fig. 4, the method mainly includes the following steps:

s401: in a first time period, the open function network element receives a monitoring event report which is sent by the monitoring network element and corresponds to one or more terminals in the terminal group.

S402: when the first time period is exceeded, the open function network element determines a target monitoring event report corresponding to one or more terminals; the target monitoring event report is a monitoring event report of one or more terminals which is received by the open function network element at the latest time.

S403: and the open function network element sends a first message, wherein the first message comprises a target monitoring event report corresponding to one or more terminals.

In S401, the time length of the first time period may be obtained according to a preset time length and/or a preset monitoring duration. Specifically, in the first aspect, the Time length of the first Time period may be a preset Time length, such as a Group Reporting Guard Time (e.g., a Group Reporting Guard Time). The group reporting guard time is a time interval which is configured in advance by the service server for the terminal group requesting monitoring in the open function network element, and for partial monitoring with weak timeliness, the service server can enable the open function network element to report the monitoring event of the terminal group to the target address according to the group reporting guard time interval by setting the group reporting guard time, so as to reduce the number of times for reporting the monitoring event report by the open function network element.

In the second aspect, the time length of the first period may also be a preset monitoring duration. Specifically, the monitoring request sent by the service server to the open-function network element further includes a monitoring duration, the service server may agree, through the monitoring duration, a total duration of the monitoring service for the terminal group with the open-function network element and the monitoring network element, when the monitoring duration is exceeded, the monitoring network element may stop monitoring the terminals in the terminal group, and then the open-function network element may perform subsequent S402 according to monitoring event reports respectively corresponding to the terminals in the terminal group reported by the monitoring network element within the monitoring duration.

In the third aspect, the time length of the first time period may also be obtained according to a preset time length and/or a preset monitoring duration. Specifically, the monitoring duration may not be an integral multiple of a preset time length (e.g., group reporting guard time), and based on this, the first time period in this embodiment may also be a time length before the monitoring duration reaches, which is obtained according to the preset time length and the monitoring duration, and if the monitoring duration is T and the preset time length is T1, the event length of the first n (n is greater than or equal to 1) first time periods in the monitoring duration is a preset time length T1, and the time length of the n +1 first time period is T2, where T2 is T mod T1, or T2 is T1+ T mod T1, and mod is a remainder operation.

A specific example is shown, the group reporting guard time is 10min, the monitoring duration is 10 hours and zero 5min, then the open-function network element sends a first message to the target address every 10min within the first 10 hours after starting monitoring, and after the monitoring duration is long, the open-function network element determines a target monitoring event report corresponding to one or more terminals in the terminal group according to a monitoring event report received by the monitoring network element within the last 5min, and sends the last first message to the target address.

In the following, group reporting guard time is taken as an example, and it should be understood that the following embodiments are still applicable in the case that the time length of the first time period is obtained according to the monitoring duration and the preset time length.

In S402, the period length of the internal timer of the open-function network element may be configured as the group reporting guard time, and the open-function network element may determine whether the group reporting guard time is exceeded according to the timer. It should be understood that exceeding the group reporting guard time does not represent that the open-function network element stops receiving the monitoring event report sent by the monitoring network element, that is, after the current group reporting guard time is exceeded, the internal timer of the open-function network element is reset, so that the open-function network element enters the next group reporting guard time. In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, in a case that no specific description is given, the embodiments of the present application only describe a group reporting daemon time.

In this embodiment of the present application, the monitoring time report of the terminal that is received by the open function network element at the latest time may be a latest monitoring event report (the last report) corresponding to the terminal that is received by the open function network element within the group reporting guard time, and the monitoring event report may correspond to a monitoring event that occurs at the latest time from the terminal to the current time. After the group reporting guard time is exceeded, the open function network element may determine, for each terminal that receives a corresponding monitoring event report within the group reporting guard time, a monitoring event report (latest monitoring event report) corresponding to the terminal that is received the latest time, as a target monitoring event report of the terminal.

In a specific implementation process, each terminal in the terminal group may correspond to one or more monitoring event reports (as shown in fig. 3), or a plurality of terminals may correspond to one monitoring event report, and the process of determining the target monitoring event corresponding to the terminal in the two cases is similar, which is described in the following with the corresponding relationship shown in fig. 3 as an example.

It is assumed that the monitoring event report of the terminal group a received by the open-function network element within the group reporting guard time is as shown in fig. 3, and the open-function network element receives the monitoring event reports of the terminal 1, the terminal 2, the terminal 3, and the terminal 4 within the group reporting guard time. When the group reporting guard time is exceeded, the open function network element may determine the target monitoring event reports corresponding to the terminal 1, the terminal 2, the terminal 3, and the terminal 4, respectively. Specifically, the open function network element may respectively determine: the target monitoring event report corresponding to the terminal 1 is a monitoring event report 15, the target monitoring event report corresponding to the terminal 2 is a monitoring event report 23, the target monitoring event report corresponding to the terminal 3 is a monitoring event report 31, and the target monitoring event report corresponding to the terminal 4 is a monitoring event report 42.

It should be understood that, in the present application, the target monitoring event is a monitoring event report of a terminal that is received by the open-function network element last time, and when it is considered that a sequence in which the open-function network element receives the monitoring event report is inconsistent with a sequence in which the monitoring event report is reported by the monitoring network element due to network delay, packet loss, and the like, the target monitoring event may also be a monitoring event report of which the occurrence time of the corresponding monitoring event is the latest among a plurality of monitoring event reports corresponding to terminals that are received by the open-function network element within the first time period. Based on this, in order to facilitate the open-function network element to more accurately determine the target monitoring event report corresponding to the terminal, in a possible implementation manner, the open-function network element receives a sequence number and/or a timestamp of a monitoring event report corresponding to one or more terminals sent by the monitoring network element, and then the open-function network element may determine the latest monitoring event report corresponding to the received terminal according to the sequence number and/or the timestamp of the monitoring event report.

Specifically, in S202 shown in fig. 2, when reporting the monitoring event report corresponding to the terminal to the open-function network element, the monitoring network element also reports a sequence number and/or a timestamp of the monitoring event report to the open-function network element. Wherein the timestamp of the monitoring event report may be generated according to the occurrence time of the monitoring event of the terminal. The open function network element may determine, according to the sequence number and/or the timestamp of the monitoring event report, the time at which the monitoring event corresponding to the monitoring event report occurs, so that the monitoring event report corresponding to the latest time at which the monitoring event occurs may be determined from the multiple monitoring event reports corresponding to the terminal as the target monitoring event report. The sequence number of the monitoring event report may be generated according to the occurrence sequence of the monitoring events of the terminal, and the open-function network element may determine the occurrence sequence of the monitoring events corresponding to the monitoring event report according to the sequence number of the monitoring event report, for example, if the monitoring network element monitors that the monitoring event a occurs in the terminal 5, and the monitoring event a is the 100 th monitoring event occurring in the terminal 5, the monitoring network element generates a monitoring event report a corresponding to the monitoring event a and the sequence number of the monitoring event report a, and reports the monitoring event report a and the sequence number of the monitoring event report a to the open-function network element, and the open-function network element may determine that the monitoring event a corresponding to the monitoring event report a is the 100 th monitoring event occurring in the terminal 5 according to the sequence number of the monitoring event report a. Similar to the timestamp, the open function network element may also determine, according to the sequence number of the monitoring event report, a monitoring event report whose corresponding monitoring event occurrence time is latest from a plurality of monitoring event reports corresponding to the terminal, as the target monitoring event report.

In the specific implementation of S202, the monitoring event report of the terminal and the timestamp and/or the sequence number of the monitoring event report may be reported to the open function network element through a message. In particular implementations, the sequence number may also serve as a report ID for the message. For example, the monitoring network element monitors the terminal 1, determines an occurrence sequence of a monitoring event corresponding to the monitoring event report 12 in the monitoring event of the terminal 1 before the terminal 1 reports the monitoring event report 12, for example, the monitoring event corresponding to the monitoring event report 12 is a 20 th monitoring event occurring in the terminal 1, and generates a report ID of a message according to the occurrence sequence of the monitoring event corresponding to the monitoring event report 12, where the message includes the monitoring event report 12. The network element with an open function may determine, according to the report ID of the message, an occurrence order of the monitoring event corresponding to the monitoring event report 12 in the monitoring event of the terminal 1, and further determine a target monitoring event corresponding to the terminal 1.

In a possible implementation manner, since one monitoring network element may simultaneously monitor a plurality of terminals in one terminal group, when a monitoring event occurs to a plurality of terminals at the same time, the monitoring network element may generate monitoring event reports corresponding to the plurality of terminals and the same timestamps corresponding to the plurality of monitoring event reports, and report the monitoring event reports of the plurality of terminals and the same timestamps corresponding to the plurality of monitoring event reports to the open-function network element through one message, so as to reduce the number of messages sent by the monitoring network element to the open-function network element, thereby saving network resources. For example, in fig. 3, a terminal 1 and a terminal 2 in a terminal group a are monitored by the same monitoring network element, at a time t, a monitoring event occurs at the same time in the terminal 1 and the terminal 2, and the monitoring network element generates a monitoring event report 11 corresponding to the terminal 1 and a monitoring event report 22 corresponding to the terminal 2, so that a message sent to an open function network element by the monitoring network element includes the monitoring event report 11 corresponding to the terminal 1 and the monitoring event report 22 corresponding to the terminal 2, and a timestamp for indicating the time t.

It should be understood that, in this embodiment of the application, the target monitoring event report corresponding to the terminal determined by the open-function network element is not limited to one, and may also be the latest N monitoring event reports in the monitoring event reports corresponding to the terminals received by the open-function network element within the group reporting guard time, where N is greater than 1, for example, based on the monitoring event report shown in fig. 3, when N is 3, the target monitoring event report of the terminal 1 may be the monitoring event report 13, the monitoring event report 14, and the monitoring event report 15, and the target monitoring event report of the terminal 2 may be the monitoring event report 21, the monitoring event report 22, and the monitoring event report 23. Since the number of the monitoring event reports corresponding to the terminals 3 and 4 is less than 3, all the monitoring event reports corresponding to the terminals 3 and 4 can be used as target monitoring event reports of the terminals 3 and 4, respectively.

In S403, the first message sent by the open-function network element to the target address includes the target monitoring event report of the one or more terminals determined by the open-function network element in S402. Specifically, in the 4G network, the first message may be a monitoring indication (monitoring indication), and specifically may be an HTTP POST message, and in the 5G network, the first message may be an Nnef _ EventExposure _ Notify service operation (service operation), and specifically may be an HTTP POST message.

As described above, the monitoring request sent by the service server to the open-function network element may include the maximum reporting times, and the service server agrees the total number of monitoring event reports of each terminal in the terminal group with the open-function network element and the monitoring network element through the maximum reporting times. Specifically, when monitoring the terminals in the terminal group, the monitoring network element records the total number of monitoring event reports of the terminal reported to the open-function network element, and when the total number of the reported monitoring event reports of the terminal reaches the maximum reporting number, the monitoring of the terminal is stopped.

Based on this, in order to still determine the monitoring progress of each terminal in the terminal group, such as the remaining number of reports of each terminal, in a possible implementation manner, the first message may further include the number of monitoring event reports (number of reports) respectively corresponding to one or more terminals received by the open-function network element in the first time period. Taking the monitoring event report shown in fig. 3 as an example, the first message includes, in addition to the monitoring event report 15 of the terminal 1, the monitoring event report 23 of the terminal 2, the monitoring event report 31 of the terminal 3, and the monitoring event report 42 of the terminal 4, the number of monitoring event reports 5 of the terminal 1, the number of monitoring event reports 3 of the terminal 2, the number of monitoring event reports 1 of the terminal 3, and the number of monitoring event reports 2 of the terminal 4.

In addition, after obtaining the maximum reporting times from the monitoring request of the service server, the open-function network element may also configure the maximum reporting times locally for each terminal in the terminal group as the initial remaining reporting times corresponding to the terminal. In a possible implementation manner, after receiving a monitoring event report of any terminal in a terminal group from a monitoring network element, an open function network element subtracts 1 from the remaining number of reports corresponding to the terminal until the remaining number of reports of the terminal returns to 0. In another possible implementation manner, the open function network element may also deduct the total number of monitoring event reports of the terminals within the group reporting guard time from the remaining number of reports of each terminal locally corresponding to the open function network element in the first message while sending the first message to the target address.

It should be understood that, when the time length of the first time period is obtained according to a preset time length (such as a group reporting guard time) and a preset monitoring duration, the first message may also carry the number of monitoring event reports corresponding to the terminals received by the open-function network element in the first time period, in other words, in this embodiment of the present application, the first message may also carry the number of monitoring event reports corresponding to the terminals in the terminal group respectively received by the open-function network element since the monitoring event report was last sent to the target address.

By adopting the above scheme, the total number of the monitoring event reports corresponding to one or more terminals in the terminal group received by the open-function network element in the first time period can be determined according to the first message, so that the total number of the monitoring event reports of the terminal of the open-function network element reported by the monitoring network element can be determined for any terminal in the terminal group, and further the remaining reporting times of the terminal by the monitoring network element can be determined according to the maximum reporting times.

For the service, it only needs to obtain the current state of the terminal to provide the service for the terminal, and by adopting the above scheme provided by the embodiment of the present application, the open function network element provides the latest monitoring event report of the terminal in the terminal group for the target address through the first message, and does not report all the monitoring event reports of the terminal to the target address, so that the current state of the terminal can be determined according to the latest monitoring event report of the terminal, the number of the monitoring event reports reported to the target address is reduced, and the network resources required by the open function network element to report the monitoring event report to the target address are reduced.

Furthermore, for another part of the traffic service, it may need to acquire all monitoring event reports of the terminals in the terminal group within the first time period. Based on this, the monitoring request sent by the service server to the open-function network element may further include an indication parameter, and after the open-function network element parses the monitoring request, the indication parameter is cached and it is determined whether to send a target monitoring event report corresponding to each terminal to the target address according to the indication parameter.

In a possible implementation manner, when the service only needs to obtain the target monitoring event report of the terminal in the terminal group within the first time period, the monitoring request sent by the service server to the open-function network element includes the indication parameter, and when the service needs to obtain all the monitoring event reports of the terminal in the terminal group within the first time period, the monitoring request sent by the service server to the open-function network element may not include the indication parameter.

And after exceeding the first time period, the open function network element detects whether the monitoring parameters cached according to the query request of the service server include indication parameters. When the indication parameter is detected, the open function network element determines a target monitoring event report corresponding to one or more terminals in the terminal group, and sends a first message to a target address according to the determined target monitoring event report corresponding to the one or more terminals. When the indication parameter is not detected, the open function network element reports all monitoring event reports of the terminals in the terminal group to the target address within the first time period.

In another possible implementation manner, when the service only needs to acquire a target monitoring event report of the terminal in the terminal group within the first time period, the monitoring request sent by the service server to the open-function network element includes the first indication parameter, and when the service needs to acquire all monitoring event reports of the terminal in the terminal group within the first time period, the monitoring request sent by the service server to the open-function network element includes the second indication parameter.

And after exceeding the first time period, the open function network element inquires the indication parameters cached according to the inquiry request of the service server. And when the indication parameter is the first indication parameter, the open function network element determines a target monitoring event report corresponding to one or more terminals in the terminal group, and sends a first message to a target address according to the determined target monitoring event report corresponding to the one or more terminals. And when the indication parameter is the second indication parameter, the open function network element reports all monitoring event reports of the terminals in the terminal group in the first time period to the target address.

By adopting the method, the service server can indicate the open function network element to send all monitoring event reports of the terminals in the terminal group or the target monitoring event report of the terminal to the target address by presetting the indication parameters in the open function network element according to the service requirements of the service, thereby meeting the requirements of different service services.
