Description

Connection session control method and device for data service

technical field

The invention relates to the technical field of communication, in particular to a connection session control method and device for data services.

Background technique

In recent years, with the development of telecommunication services, especially the popularization and application of 3G equipment, more and more data services have been applied, and the usage methods tend to be large-capacity and long-term connections, among which broadband Internet access services are typical. Statistics show that users spend an average of 8 hours online every day, and the proportion of online users often exceeds 20% during busy hours. Under such a trend, the processing performance requirements for OCS (Online Charging System, integrated charging system) data services are also getting higher and higher.

The data service system under the OCS solution generally includes the following network elements:

OCS: an integrated billing system based on multiple networks and multiple billing modes;

AAA (Authentication, Authorization, and Accounting, authentication, authorization, and accounting): a network element module that implements authentication, authorization, and accounting functions in data services;

ASN-GW (Access Service Network-GateWay, access service network gateway): the underlying core network access gateway;

BS (Base Station, base station); bottom base station;

Fixed (fixed terminal), PDA (Personal Digital Assistant, personal digital assistant): a type of end user.

The prior art provides an OCS data service charging solution, that is, an "AAA+OCS" solution. In this solution, the OCS provides the real-time billing function. AAA realizes the authentication, authorization and accounting functions of data services. AAA translates the charging message sent by ASN-GW into a DCC (Diameter Credit Control, Diameter Credit Control Protocol) message and sends it to OCS for charging. The OCS data service billing process in this solution is as follows:

ASN-GW sends a service request to AAA, and AAA sends a CCR (Credit Control Request, credit control request) request to OCS after receiving the service request;

OCS approves the received CCR request, reserves funds from the user account, and then sends a reply message CCA (Credit Control Answer) to the CCR request;

After AAA receives the CCA, AAA authorizes the end user to use the corresponding service and generates an immediate credit control request;

When the user's reserved funds are about to run out or expire, AAA sends a new reservation request to OCS again, OCS reserves funds from the user's account again, and replies the corresponding amount to AAA, and AAA reserves the amount for the user update accordingly;

When the user account is used up or the enabled service is about to end, AAA sends a message to terminate the credit control service to OCS, and the message contains AVP (Attribute Value Pairs, attribute-value pair) identifying the service termination time;

OCS needs to return the remaining reserved amount to the user's account and make a deduction.

In the process of realizing the present invention, the inventor found that the above-mentioned prior art has the following deficiencies:

In the implementation of existing data service billing schemes, for data services with large capacity and long connections, online calls often generate no traffic or very small traffic for a period of time, such as Trojan horses or viruses in the machine. small traffic. However, in order to maintain calls, AAA and OCS need to maintain all connection sessions for a long time, which consumes a lot of system performance, greatly limits the ability to support data services, and is not conducive to the application of large-capacity long-connection data services.

Contents of the invention

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

As shown in FIG. 1, in the embodiment of the present invention, the flow of the connection session control method for data services may include:

Step 101, when the connection session of the data service does not generate billing traffic or the billing traffic generated is less than a threshold within the set time period, save the relevant information of the connection session;

Step 102, release the resources occupied by the connection session, and make the connection session enter a dormant state.

As can be seen from the flow shown in Figure 1, in the embodiment of the present invention, when the connection session of the data service does not generate billing traffic within the set duration or when the billing traffic generated is less than the threshold, the relevant information of the connection session is saved, And release the resources occupied by the connection session, so that the connection session enters a dormant state, which can reduce the consumption of system memory by data services, improve the performance of data services, and support capabilities for data services, which is conducive to the development of large-capacity long-connection data services application.

The process shown in Figure 1 and its specific implementation can be completed by devices that can realize its functions, such as AAA or OCS. The following uses AAA as an example to illustrate:

During specific implementation, before step 101 is executed, it may also include: AAA monitors the connection session of the data service; it can be seen that by monitoring and accumulating the size of the charging flow of the data service, the purpose of real-time control of the state of the data service connection session can be achieved.

In one embodiment, the monitoring of the connection session of the data service may be specifically implemented as: scanning the status of the connection session of the data service in real time, and accumulating the billing traffic of the connection session of the data service within a set time period.

In an embodiment, when the connection session generates no charging traffic or the generated charging traffic is less than a threshold within the set time period, the converged charging system OCS may also be notified to put the connection session into a dormant state. Specifically, it may be implemented as: sending a CCR message to the OCS, where the CCR message is used to notify the OCS to trigger the connection session to enter a dormant state.

In one embodiment, before the AAA saves the relevant information of the connection session of the data service, it may also include: receiving a credit control response CCA message from the OCS, the CCA message is used to instruct the OCS to trigger the connection session to enter the dormant state according to the CCR message Result; if the result is that the OCS successfully triggers the connection session to enter the dormant state according to the CCR message, the AAA may perform an operation of saving the relevant information of the connection session. In the embodiment of the present invention, triggering the connection session of the data service to enter the dormant state includes: saving the relevant information of the connection session, releasing the resources occupied by the connection session, and making the connection session enter the dormant state.

During specific implementation, for a data service connection session in a dormant state, the relevant information of the connection session will be stored in the physical storage medium instead of being stored in the memory module; after saving, the resources occupied by the connection session will be released, For example, memory space, session number, etc. That is, after receiving the CCA message sent by the OCS, it is judged whether the connection session of the OCS according to the CCR message data service is dormant successfully. The session enters the dormant state, saves the relevant information of the connection session, and releases the resources occupied by the connection session. If it fails, it can wait for the next attempt to sleep.

In one embodiment, when the received traffic consumption information or the accumulative billed traffic of the connection session of the data service is greater than the threshold, an activation request for activating the connection session may be sent to the OCS. Similarly, the AAA may activate the connection session at the local side if it subsequently receives a response message indicating that the connection session is successfully activated returned by the OCS. Specifically, when the session is activated, the stored relevant information of the connection session can be read from the physical storage and loaded into the memory module, thereby activating the connection session that was originally in a dormant state.

By dormant and activating the data service connection session, it can solve the problem of serious system performance consumption caused by maintaining the session for a long time when the long-term connection and large-capacity data service are used, thereby reducing the occupation of the system memory by the large-capacity long-connection data service Consumption, improve data service performance, and improve support for long-connection data services.

During specific implementation, there are many ways to realize that the CCR message is used to notify the connection session that triggers the data service to enter the dormant state. The connection session goes to sleep, for example:

Extend the dormancy notification field Dormancy-Message in the CCR message. The meaning of the value of this field can be:

0 indicates that the connection session of the data service is active; 1 indicates that the connection session of the data service enters the dormant state.

By extending the CCR message, the dormant connection session can be dynamically notified, and the related resources of the connection session, including memory, session number and other resources, can be released to reduce the memory loss caused by maintaining the long-term connection session, thereby improving the performance of supporting long-term connection data services.

In addition to extending the CCR message, it is also possible to determine whether the connection session that triggers the data service needs to be notified to enter the dormant state by monitoring whether the charging request message is reported within a fixed period of time. When there is no billing request message reported within a fixed period of time, it will automatically enter the dormant state, and the session will not be activated until the next billing request message is received, or released after the message times out.

During specific implementation, there may be multiple ways to implement the CCA message to indicate that the OCS triggers the connection session to enter the dormant state according to the CCR message. For example, it may include: the CCA message is extended with a dormancy type field and a dormancy result field. The field is used to indicate whether the OCS triggers the connection session to enter the dormant state, and the dormancy result field is used to indicate whether the OCS successfully triggers the connection session to enter the dormant state, for example:

Extend the dormant type field in the CCA message:

Dormancy-Type, the meaning of the value of this field is: 0 indicates that the connection session of the data service is in the active state, and 1 indicates that the connection session of the data service is in the dormant state;

Extend the dormant result field in the CCA message:

Dormancy-Result, the meaning of the value of this field is: 0 indicates that the connection session of the data service fails to dormant, and 1 indicates that the connection session of the data service does not dormant successfully.

Next, take OCS as an example to illustrate the specific implementation of the process shown in Figure 1:

As shown in Figure 2, in this example, the process of OCS triggering the connection session of the data service to enter the dormant state may include:

Step 201: When the connection session of the data service generates no billing traffic within the set time period or the billing traffic generated is less than the threshold, receive a CCR message from the AAA, which is used to notify the triggering of the connection session of the data service to enter dormant state;

Step 202: According to the CCR message, save the relevant information of the connection session, and release the resources occupied by the connection session, so that the connection session enters a dormant state.

After receiving the CCR message, the OCS triggers the connection session of the data service to enter a dormant state, saves the relevant information of the connection session of the data service, and releases the resources occupied by the connection session of the data service.

In an embodiment, after triggering the connection session on the local side to enter the dormant state according to the CCR message, the method may further include: sending a CCA message to the AAA, where the CCA message is used to indicate the result of triggering the connection session on the local side to enter the dormant state.

If an activation request for activating the connection session is subsequently received from the AAA, the dormant connection session at the local side may also be activated according to the activation request. The implementation may include: reading the saved information about the connection session, activating the session in the dormant state, so as to start the subsequent message processing flow.

Similar to the process shown in Figure 1, during specific implementation, there may be multiple ways to realize that the CCR message is used to notify the connection session that triggers the data service to enter the dormant state, for example: it may include: the CCR message is extended with a dormancy notification field, and the dormancy notification The field is used to notify the connection session that triggers the data service to enter the dormant state.

There may also be multiple ways to implement the CCA message to indicate the result of triggering the connection session on the local side to enter the sleep state. For example, it may include: the CCA message is extended with a sleep type field and a sleep result field, and the sleep type field is used to indicate whether The connection session is triggered to enter the dormant state, and the dormancy result field is used to indicate whether the connection session is successfully triggered to enter the dormant state.

The specific implementation of the method in the embodiment of the present invention will be described below by taking the connection session control method for realizing the above-mentioned data service by using OCS and AAA as an example.

Fig. 3 shows the processing flow of the connection session control method of the data service in this example, and the processing flow may include:

Step 301, AAA receives a charging request;

Step 302, AAA sends a CCR message to the OCS;

Step 303: After receiving the CCR message, the OCS performs price approval processing, including authentication, reverse calculation, etc., and performs fund reservation processing from the user account;

Step 304, the OCS returns a CCA message to the AAA;

Step 305: After receiving the CCA message, the AAA authorizes the terminal user to use the corresponding service, and generates an immediate credit control request, including invoking the service component and determining the connection parameters;

Step 306, AAA monitors the connection session of the data service;

Step 307, AAA determines that the connection session of the data service does not generate traffic consumption within the set time period, or the accumulated billing traffic is less than the threshold;

Step 308, AAA sends a CCR message to the OCS, and the CCR message carries information to inform the OCS side that the connection session of the data service can enter a dormant state;

Step 309, after the OCS receives the CCR message notifying the dormant session from the AAA, triggers the connection session of the data service to enter the dormant state;

Step 310, the OCS feeds back a CCA message to the AAA, notifying the dormancy result and dormancy type;

Step 311, AAA judges the dormancy result in the received CCA message, if successful, triggers the data service connection session on the AAA side to also enter the dormant state, otherwise it does not enter, and continues to try dormancy next time;

Step 312, when the funds reserved by the user are about to run out or expire, AAA receives a request to continue applying for data services;

Step 313, AAA reads the relevant information of the previously saved data service connection session according to the application charging information in the received request to continue to apply for the data service, and activates the connection session;

Step 314, AAA sends a CCR message to OCS, requesting deduction;

Step 315, the OCS receives the AAA deduction request message, reads the previously saved information about the data service connection session, and activates the connection session;

Step 316, OCS performs price approval processing, including authentication, reverse calculation, etc., and performs fund reservation processing from the user account;

Step 317, OCS replies the corresponding amount to AAA through ACS;

Step 318, AAA continues to monitor the connection session of the data service;

Step 319, the user account is used up or the enabled service is about to be terminated;

Step 320, AAA sends a message of terminating credit control service to OCS through CCR;

Step 321, the OCS performs price approval processing and account processing, and ends the session;

Step 322, OCS returns CCA to AAA;

Step 323, AAA releases the connection.

Another example is given below to illustrate the dormancy and activation processes of the connection session of the data service respectively.

In this example, OCS and AAA are still used to implement the connection session control method of the above-mentioned data service. In addition, in this example, the dormancy notification field Dormancy-Message is also extended in the CCR message. The meaning of the value of this field is: 0 means the data service The connection session is active; 1 indicates that the connection session of the data service is in the dormant state;

Extend the dormancy type field in the CCA message: Dormancy-Type, the meaning of the value of this field is: 0 indicates that the connection session of the data service is in the active state, and 1 indicates that the connection session of the data service is in the dormant state;

Extend the dormancy result field in the CCA message: Dormancy-Result, the meaning of the value of this field is: 0 indicates that the connection session of the data service fails to dormant, and 1 indicates that the connection session of the data service does not dormant successfully.

As shown in Figure 4, the connection session dormancy processing flow of the data service in this example may include:

Step 401, during data service charging, AAA monitors the connection status of the current charging session;

Step 402, regardless of whether the current session is monitored by duration/flow/duration&flow, AAA is accumulated within the preset duration, and the billing traffic generated by the current session;

Step 403, judging that the accumulated charging traffic within the current preset time is equal to 0, or less than a certain threshold (the threshold can be configured on the AAA), if the condition is met, then execute step 404, otherwise execute step 405;

Step 404, send a CCR (update) message, and set the value of Dormancy-Message in the CCR message as 1. The session enters the dormant state, and executes step 406;

Step 405, setting the value of Dormancy-Message in the CCR message as 0 session activation state, or not passing the AVP;

Step 406, the OCS system receives the CCR message and processes it;

Step 407, judge whether the value of Dormancy-Message is equal to 1 and the session enters the dormant state, if it is equal to 1, execute step 409, otherwise execute step 408;

Step 408, the normal CCR billing process processing, returns the CCA message normally, and the processing ends;

Step 409, OCS dormancy session, if the dormancy is successful, then perform step 410, if the dormancy fails, perform step 411;

Step 410, Dormancy-Type=1 session dormancy state in the CCA message, Dormancy-Result=1 session dormancy success, execute step 412;

Step 411, Dormancy-Type=0 session activation state in the CCA message, Dormancy-Result=0 session dormancy failed;

Step 412, AAA receives the CCA message and processes it;

Step 413, judging Dormancy-Type=1 session dormancy state, Dormancy-Result=1 session dormancy is successful, if satisfied then execute step 414, otherwise execute step 48;

Step 414, AAA sleeps the session, waits for the session to be activated, and the sleep process ends.

As shown in Figure 5, the connection session activation process of the data service in this example may include:

Step 501, during data service charging, AAA monitors the connection status of the current charging session;

Step 502, regardless of whether the current session adopts the monitoring method by duration/flow/duration&flow, AAA is accumulated within the preset duration, and the billing traffic generated by the current session;

Step 503, judging whether the accumulated billing traffic within the current preset time is greater than the threshold (the threshold can be configured on AAA), if the condition is met, then execute step 504, otherwise execute step 508;

Step 504, encoding CCR (update) message;

Step 505, set the value of Dormancy-Message in the CCR message as 0 session activation state, and send the message;

Step 506, the OCS system receives the CCR message and processes it;

Step 507, judge whether the value of Dormancy-Message is equal to 0 session activation state, if equal to 0, execute step 509, otherwise execute step 508;

Step 508, the non-session activated CCR charging process is processed, and the CCA message is returned normally, and the processing ends;

Step 509, OCS activates the session, if the activation is successful, execute step 510, and if the activation fails, execute step 511;

Step 510, Dormancy-Type=0 session activation state in the CCA message, Dormancy-Result=0 session dormancy failed, execute step 512;

Step 511, Dormancy-Type=1 session dormancy state in the CCA message, Dormancy-Result=0 session dormancy failure;

Step 512, AAA receives the CCA message and processes it;

Step 513, judging Dormancy-Type=0 session activation status and Dormancy-Result=0 session dormancy failure, if satisfied then execute step 514, if not satisfied execute step 515;

Step 514, AAA activates the session, and the activation process ends;

Step 515, retry the session activation process until the maximum number of times or the session is released after failure, and the process ends.
