Description

Service processing method, device and readable medium

Technical Field

The present invention relates to the technical field of core networks, and in particular, to a service processing method, apparatus and readable medium.

Background

At present, the Quality of Service (QOS) slowdown Service needs to be urgent, especially for the parent-child guard market. Many teenagers are indulged in online games, parents hope that the parents can send prompt messages to the parents 'mobile phones during playing games, and therefore the parents can reduce the current online speed of the children's mobile phone numbers to a value incapable of bearing the game requirements by selecting the speed limiting function, and therefore the children are prevented from being indulged in the games.

At present, when the QOS slow-down service developed by the existing network encounters an Application Function (AF)/Application Access Control (AAC), which cannot address a Policy and Charging Rules Function (PCRF) to which a mobile phone number of a user belongs, the Policy and Charging Rules Function (PCRF) in the prior art provides a solution that: AF (AAC) sending AAR (AA-Request AA Request) message to all PCRF in PCRF POOL belonging to subscriber number (MSISDN) segment; after each PCRF in the PCRF POOL receives the AAR message, the MSISDN is matched with the user currently in charge of management and control, if the MSISDN is matched with the user, the AAR message is accepted, and the policy and control of PCC (policy and charging control) of the user is executed through a Gx interface subsequently; if not, the AAR message is ignored. The disadvantages of this solution are mainly represented by: the Rx interface message volume is multiplied, especially after the PCRF changes to the distributed architecture (front-end function FE + user database function BE), AAR messages are sent to all FEs, resulting in an increase in DRA and PCRF load, but most of the messages are useless signaling.

Detailed Description

The service processing method, the device and the readable medium provided by the embodiment of the invention are used for reducing the signaling consumption on the premise of realizing the QOS deceleration service.

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.

As shown in fig. 1, a flow diagram of a service processing method provided in an embodiment of the present invention may include the following steps:

s11, when detecting that the target user uses the service needing to be decelerated, the third party platform sends a service deceleration request to AF (ACC).

The service deceleration request in the invention carries the internet protocol IP address of the target user and the user number of the target user.

Specifically, taking the target user as a child as an example, in order to prevent the child from being enthusiastic in some services, such as games, etc., the parent of the child will handle the deceleration services of these services for the user number of his child. When the target user is using the slowed down service, the operator of the target user monitors the event and then sends the event to the user number of the parent of the child to alert the child parent that the child is using the slowed down service.

On this basis, a child parent may send a service slowdown instruction of a service being used by a target user (child) to a third party platform or a user server CP by using a terminal device, where the instruction carries a user number of the target user, so that the third party platform or CP may receive the service slowdown instruction sent by the child parent, determine, based on the service slowdown instruction, an IP address of the service being run by the target user based on the user number of the target user, and then send a service slowdown request of the service being used by the target user to an af (acc), where the service slowdown request needs to carry the user number of the target user and the IP address of the service being run by the target user in order to accurately complete the slowdown of the service of the target user.

Optionally, the user number in the present invention may be, but is not limited to, a mobile phone number, etc., for convenience of description, and the following description takes the mobile phone number as an example.

S12, af (aac), after receiving a service slowdown request of a service being used by a target user, determining a PCRF to which the target user belongs according to an IP address and a user number of the target user and a correspondence between the user number, the IP address, and identification information of the PCRF in the correspondence list.

In this step, the af (acc) stores a list of correspondence between the user number, the IP address, and the identification information of the PCRF, as shown in reference table 1:

TABLE 1

Subscriber number	IP address	Identification information of PCRF
			Mobile phone number 1	IP1	PCRF hostname 1
Mobile phone number 2	IP2	PCRF hostname 2
			……	……	……

In table 1, the user number is a mobile phone number, and the identification information of the PCRF is a host name of the PCRF. After receiving the service slowdown request, the host name of the PCRF to which the target user belongs may be determined according to the correspondence in table 1, and the user number and the IP address of the target user carried in the service slowdown request.

S13, AF (AAC) sending a service control request to the PCRF to which the target user belongs.

Because the main body for implementing the QOS deceleration service is the PCRF, after the host name of the PCRF to which the target user belongs is determined, the service management and control request is sent to the PCRF.

Specifically, af (aac) sends a traffic policing request to the PCRF by sending an AAR message.

And S14, the PCRF to which the target user belongs manages and controls the service.

In this step, after receiving the service management and control request, the PCRF to which the target user belongs performs service management and control on the service being used by the target user. Specifically, the PCRF may use the existing QOS management and control specification to manage and control the service being used by the user.

By implementing the procedures shown in steps S11 to S14, af (acc) may accurately determine the PCRF to which the target user belongs based on the correspondence between the stored user number, IP address, and identification information of the PCRF after receiving the service slowdown request of the service being used by the target user, and then let the PCRF perform slowdown control on the service being used by the target user in time, thereby effectively preventing the target user from using the service for an excessively long time, and further preventing the target user from being addicted to the service.

Optionally, the IP address of the target user in the present invention includes a public network IP address or a private network IP address; the IP addresses in the correspondence list include private network IP addresses and public network IP addresses, as shown in reference table 2:

TABLE 2

Subscriber number	Private network IP address	Public network IP address	Identification information of PCRF
				Mobile phone number 1			PCRF hostname 1
Mobile phone number 2			PCRF hostname 2
				……	……	……	……

Based on the fact that the private network IP address and the public network IP address are stored in the corresponding relation list, the PCRF to which the target user belongs can be found more accurately.

If the IP address of the target user is a public network IP address, before implementing step S13, the method further includes:

and determining the private network IP address of the target user according to the IP address and the user number of the target user and the corresponding relation among the user number in the corresponding relation list, the IP address and the identification information of the policy and charging rule functional unit PCRF.

In this step, since the PCRF to which the target user belongs needs to find the private network IP address of the service used by the target user when performing service management and control on the service being used by the target user, the service management and control on the service being used by the target user can be implemented, therefore, the af (acc) may also determine the private network IP address of the service to be managed and controlled used by the target user based on the correspondence list in table 2.

On this basis, step S13 may be performed according to the following procedure:

In this step, in order to facilitate the PCRF to which the target user belongs to accurately find the target user to be subjected to management and control, when sending the service management and control request to the PCRF to which the user belongs, the PCRF carries the private network IP address of the target user and the user number of the target user in the service management and control request and sends the service management and control request to the PCRF to which the target user belongs.

Optionally, if the IP address of the target user is a public network IP address, step S12 may be implemented according to the flow shown in fig. 2, including the following steps:

s21, determining the firewall identification corresponding to the public network IP address according to the public network IP address of the target user.

Optionally, the correspondence list provided in the present invention further stores a firewall identifier of a firewall to which the public network IP address belongs, and the correspondence list refers to table 3:

TABLE 3

Subscriber number	Private network IP address	Firewall identification	Public network IP address	Identification information of PCRF
					Mobile phone number 1		IP-Domain-ID1		PCRF hostname 1
Mobile phone number 2		IP-Domain-ID2		PCRF hostname 2
					……	……		……	……

For example, the firewall identifier is IP-Domain-ID, and the af (acc) may determine the firewall identifier to which the public network IP address of the target user belongs from the correspondence list shown in table 3 according to the public network IP address of the target user, thereby reducing the search range of the PRFC.

S22, under the firewall corresponding to the firewall identification, determining the identification information of the PCRF corresponding to the user number of the target user based on the corresponding relationship between the user number and the identification information of the PCRF.

In this step, after the firewall identifier to which the public network IP address belongs is determined based on step S21, the determined firewall is taken as the SGi/Gi for example, and then, the identification information of the PCRF corresponding to the user number of the target user is determined under the SGi/Gi firewall.

S23, determining the PCRF corresponding to the identification information of the determined PCRF as the PCRF to which the target user belongs.

In this step, the PCRF corresponding to the identification information of the PCRF determined in step S22 is determined as the PCRF to which the target user belongs.

Optionally, the correspondence list in the present invention may further include identification information of a Packet Data Network GateWay (PGW), which is described with reference to table 4 by taking the identification information of the PGW as a PGW host name as an example:

TABLE 4

Based on table 4, after receiving the service slow-down indication, the third party platform or CP may further determine the PGW host name of the service being used by the target user, and then send the PGW host name, the private network IP address of the target user, and the user number of the target user to the af (acc) after carrying the service slow-down request. In this way, the af (acc) may determine, based on the firewall identifier corresponding to the PGW host name and the public network IP address, the identification information of the PCRF corresponding to the user number of the target user under the firewall corresponding to the firewall identifier, so as to more accurately determine the PCRF to which the target user belongs.

Optionally, a corresponding relationship between the user number, the IP address, and the PCRF may be established according to the procedure shown in fig. 3, which is described by taking the user equipment of the target user as the UE as an example, and when the UE runs a service that handles speed reduction, the method includes the following steps:

s31, the UE sends an attach request to the MME, and the attach request carries the user number of the target user.

Specifically, the target user sends an attach request to the MME during an attach procedure of an Evolved Packet Core (EPC) based on its UE.

S32, the MME sends a session creation request to the PGW, where the session creation request carries the user number.

In this step, after receiving the attach request, the MME sends a session establishment request to the PGW, and the session establishment request carries a subscriber number of the target user and the like in order to smoothly slow down the service handling the slow down.

And S33, the PGW forwards the session creation request to the PCRF to which the target user belongs.

After receiving the session creation request, the PCRF may determine the identification information of the PGW that sent the session creation request. Specifically, the identification information of the PGW in the present invention may be, but is not limited to, a hostname of the PGW, and the like.

In specific implementation, the PGW may send a session creation request through a CCR-I signaling message.

S34, after receiving the session creation request, the PCRF to which the target user belongs determines whether the target user transacts the speed-down service based on the user number of the target user when determining that the target user is attached.

Specifically, an extension field is preconfigured in the PCRF, where the extension field is used to indicate whether a target user has handled a speed reduction service, that is, the extension field is: and if the extended field is set to be 'yes', determining that the target user registers AF (ACC), otherwise, determining that the target user does not register AF (ACC).

In specific implementation, when a child parent thinks that the child needs to handle the speed reduction service, the child (target user) will handle the speed reduction service for some services to the business hall, so that the PCRF will write the set value "yes" in the extension field of the target user.

On the basis, the PCRF determines that the user transacts the speed reduction service according to the following method:

and the PCRF determines the value of the pre-configured extension field as a set value.

In this step, after receiving the session creation request, the PCRF searches for a value of an extension field corresponding to the user number based on the user number carried in the request, and if the value is determined to be "yes", determines that the target user is registered at the af (acc), which indicates that the target user belongs to a QOS acceleration user, then executes step S35.

S35, PCRF belonging to target user sends attach notice to AF (ACC).

In this step, after determining that the target user registers with the af (acc) based on step S34, the PCRF to which the target user belongs reports an RAR message to the af (acc), so as to send an attach notification of the target user attaching to the EPC network to the af (acc).

S36, af (acc) add the corresponding relationship between the user number of the target user, the IP address of the target user, and the identification information of the PCRF to which the target user belongs to the corresponding relationship list.

In this step, after receiving the attach notification of the PCRF to which the target user belongs, the af (acc) adds the user number of the target user, the PGW host name, the IP address of the target user, and the identification information of the PCRF to which the target user belongs to the correspondence list shown in table 4. Specifically, the IP address of the target user in the present invention may be, but is not limited to, a public network IP address and a private network IP address of the target user.

It should be noted that the mapping relationship between the PGW host name, the firewall identifier and the public network IP address is known in the current network planning and is configured in advance.

Optionally, the service processing method provided by the present invention may further include a flow shown in fig. 4, including the following steps:

s41, the UE sends a detach request to the MME, wherein the detach request carries the user number of the target user.

In this step, in order to prevent the PCRF from always performing the speed-limiting processing on the traffic of the target user that has handled the speed reduction, the target user may normally use the traffic within a period of time, and when the target user is detached (the traffic is closed), the relevant information of the target user may be deleted from the correspondence list shown in table 4.

On the basis, when the target user is detached, the UE of the target user sends a detachment request to the MME.

S42, the MME sends a delete session creation request to the PGW, where the delete session creation request carries the user number.

In this step, after receiving the detach request, the MME sends a delete session creation request to the PGW, and the delete session creation request also needs to carry a user number of the target user.

And S43, the PGW forwards the request for creating the deletion session to the PCRF to which the target user belongs.

In this step, after receiving the delete session creation request, the PCRF may determine the identification information of the PGW that sent the delete session creation request. Specifically, the identification information of the PGW in the present invention may be, but is not limited to, a hostname of the PGW, and the like.

S44, after receiving the request for creating deletion session, the PCRF attributed to the target user sends a logout notification to the af (acc).

In this step, the PCRF to which the target user belongs sends a logout notification to the af (acc) after receiving the delete session creation request, and sends the user number of the target user to the af (acc).

S45, af (acc) deletes the correspondence between the user number, IP address, and identification information of the PCRF that belongs to the target user from the correspondence list according to the logout notification.

In this step, af (acc) deletes the correspondence between the user number and IP address of the target user and the identification information of the PCRF to which the target user belongs from the correspondence list shown in table 4 after receiving the logout notification, so that the target user can use the service at normal speed when he uses the service that has handled speed reduction next time, and at the same time, the target user can initiate an attach request when he uses the service next time, so that the PCRF sends the information of the user number, public network IP address, identification information of the PCRF, and the like of the target user to af (acc) so that af (acc) adds the received correspondence to the correspondence list until the service speed reduction request for the service is received, and the service processing method provided by the present invention is used to manage and control the service. Therefore, the target user can normally use the service within a period of time, the condition that the service is controlled for a long time is avoided, the condition that the target user uses the service and prevents the target user from drowning in the service is met, and the effect of service control is achieved.

The service processing method provided by the invention is adopted to receive the service deceleration request of the service used by the target user, wherein the service deceleration request carries the Internet protocol IP address of the target user and the user number of the target user; determining the PCRF to which the target user belongs according to the IP address and the user number of the target user and the corresponding relation among the user number in the corresponding relation list, the IP address and the identification information of the PCRF; and sending a service control request to the PCRF to which the target user belongs, and controlling the service by the PCRF. The PCRF to which the target user belongs can be accurately determined through the corresponding relation list, so that the PCRF effectively performs management and control processing on services needing management and control, and the problem that the PCRF cannot be addressed by AF (ACC) in QOS (quality of service) management and control services in the prior art is solved; in addition, the invention realizes the management and control of the service in the signaling interaction process in the prior art, thereby avoiding the hidden trouble of sudden increase of the useless message quantity of the Rx interface; in addition, the method can be realized only by changing PCRF and AF (ACC) software, avoids the work of modifying a large amount of PGWs in the current network, and is beneficial to the quick implementation of the service processing method provided by the invention.
