Description

Session processing method, system and device

The present application claims priority to Chinese Patent Application No. 20071030509 3.9, the entire disclosure of which is hereby incorporated by reference. in.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a session processing method, system, and apparatus.

Background technique

The NGN network architecture developed by TISPAN (Telecommunications and Internet Converged Services and Protocols for Advanced Networking, Telecommunications and Internet Convergence Services and Advanced Networks) uses subsystem-oriented design ideas. The network architecture can adapt to new business requirements over time, and facilitate the introduction of new subsystems from other standards organizations, and each subsystem is a collection of functional entities and interfaces, and its internal architecture can be flexibly adjusted. Does not affect other subsystems. In the actual application process, the functional entities in the subsystem can be combined according to the business model, the provided business capability, and the like.

FIG. 1 is a schematic diagram of an architecture of an NGN network based on TISPA. The network architecture is divided into a service layer and a transport layer, where the service layer is composed of a core IP (Internet Protocol) multimedia subsystem, a PSTN (Public Switched Telephone Network), or an ISDN (Integrated Services Digital Network). The service digital network consists of an emulation subsystem and other subsystems. The above subsystems are collectively referred to as the AF (Application Function) subsystem. In addition, the service layer may also include some common functions such as billing function, user data management, and security management. , routing database, etc. The transport layer includes NAS (Network Attachment Sub-system) and RACS (Resource and Admission Control Sub-system). The NASS is mainly used to dynamically provide IP addresses and configuration parameters of other user equipments, to authenticate user equipment before or during IP address allocation, network access authorization, user equipment location management, and CPE (Customer Premises Equipment). , the configuration of the user premises equipment, etc.; RACS includes SPDF (Service-based Policy Decision Function) and x-RACF (Generic Resource and Admission Control Function), x-RACF can be A-RACF (Access Network RACF) or C-RACF (Core Network RACF), RACS is mainly used to provide admission control and gateway control functions. Admission control involves the operator's policy rules, resource availability, and inspection and authorization of user subscription information.

In the prior art, the session processing process between the AF and the RACS is as shown in FIG. 2:

Step 201: The AF sends a resource request for resource reservation and admission control to the session to the RACS. Step 202: The RACS determines whether sufficient resources are provided to the session, and if yes, performs steps

205; Otherwise, go to step 203.

Step 203: The RACS returns a failure response to the AF return resource and deletes the session information. Step 204: The AF rejects the user to establish a session and deletes the session information, and ends the current process.

Step 205: The RACS allocates resources to the tongue and ends the current process.

Table 1 below is an example of a prior art processing flow in which the system resources are assumed to be used by only one session:

Table 1

It can be seen from the above description that in the prior art, since resources are shared and competed between multiple tongues, when enough resources are occupied by the existing tongues, the new conversations cannot compete for sufficient resources, only When enough session resources are not occupied by other sessions or other resources are released, the new session can obtain sufficient resources. And after the session resource is released, and there is a time difference before the new session starts to use the resource, within the time difference, the released resource becomes an idle resource; and the time The greater the difference, the longer the idle time of the session resources, and the more difficult it is to use the session resources, which is not conducive to the actual operation process.

detailed description

The embodiment of the invention provides a session processing method, system and device. The session processing entity determines the maximum allowed processing time of the current tongue operation, and processes the current tongue operation in the maximum allowed processing time.

The technical solutions provided by the embodiments of the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments.

A flow chart of the first embodiment of the session processing method of the present invention is shown in FIG. 3:

Step 301: The session processing entity determines the maximum allowed processing time of the current session operation.

In the embodiment of the present invention, all the entities involved in the process of processing the session are collectively referred to as a session processing entity, and the session processing entity is a logical abstract entity, which is not limited to its specific form and deployment. For example: UE, AF, x-RACF, etc. can be abstracted into a session processing entity during a session establishment process.

Wherein, the tongue operation includes at least one of a session establishment, a tongue modification, a tongue release, or a tongue query.

The session processing entity determines that the maximum allowed processing time of the current session operation includes: the session processing entity determines the maximum allowed processing time of the current session operation according to the configuration data of the session; or the session processing entity determines, according to the input data of the terminal corresponding to the current session. The maximum allowed processing time of the current session operation; or the session processing entity determines the maximum allowed processing time of the current session operation according to the information sent by the external entity; or the session processing entity determines the maximum allowed processing time of the current session operation according to the session start time to the session termination time .

Several ways of determining the maximum allowable processing time of the current session operation listed above are described in detail below. When the session processing entity determines the maximum allowable processing time of the current session operation according to the configuration data of the session, the configuration data may be configuration data generated according to the classification of the current session operation, and the common classification may be processing the service by session and by session. The last hop session handles entity classification, classification by user level, classification by session priority, classification by session operation type, and the like. For example, according to the service classification, assuming that the service is a VOD service (Video On Demand), the maximum allowable processing time of the VOD service class session operation is 20 seconds. You can set the maximum allowable processing time for all session operations from the last hop session processing entity whose host name is "abc" to 30 seconds.

When the session processing entity determines the maximum allowable processing time of the current session operation according to the input data of the terminal corresponding to the current session, taking the current session operation as the session establishment as an example, the user may input the establishment in the user terminal when the session is established. The maximum allowed processing time of the session, the current session processing entity can obtain the maximum allowed processing time.

When the session processing entity determines the maximum allowed processing time of the current session operation according to the information sent by the external entity, when the external entity is the last hop processing entity of the current processing entity, the processing entity is processed according to the previous hop session. The sent information determines the maximum allowed processing time of the current session operation includes: the last hop session processing entity sends all sessions from the last hop session processing entity to the current session processing entity to allow the current session processing entity to adopt each of the session operations Maximum allowable processing time; or the last hop session processing entity sends to the current session processing entity all sessions from the last hop session processing entity to allow the current session processing entity to adopt the maximum allowed processing time for each of the session operations Or the last hop processing entity sends the current allowed processing time to the current session processing entity for the current allowed operation. When the external entity is the user data storage entity of the current processing entity, the maximum allowed processing time of the current session operation may be determined according to the information sent by the user data storage entity, and the user data storage entity may be a CLF (Connected Session Location and Repository Function). , connectivity session location and storage function entity), HLR (Home Location Register), HSS (Home Subscriber Server, Home Subscriber Server, SPR (Subscription Profile Repository), etc., with external entities The last hop session processing entity is consistent. When the user data storage entity sends the user data to the session processing entity, the maximum allowable processing time of all the session operations of the user, or the maximum allowed processing time of a certain type of session operation, or some The maximum allowed processing time for a session operation is sent Process the entity for the current tongue.

When the session processing entity determines the maximum allowed processing time of the current session operation according to the session start time to the session termination time, the session termination may be triggered by: when the session processing is completed, determining that the maximum allowed processing time ends; the current session operation When the session resource is preempted by other higher priority sessions, the current tongue resource is released, and the maximum allowed processing time is determined. When the last hop session processing entity receives the message indicating the end of the current session operation, such as ^ When the tongue release message, processing the revocation message, etc., it is determined that the maximum allowed processing time ends; when the message of the end session operation sent by the next hop session processing entity, such as the session exception message and the session processing failure message, is received, the maximum allowable processing time is determined. End; when the user offline message sent by the user storage entity is received, it is determined that the maximum allowed processing time ends.

Step 302: Process the current tongue operation within the maximum allowable processing time.

The processing of the current session operation in the maximum allowed processing time includes: using the maximum allowed processing time of the processing entity as an input, and calculating the maximum of the current next hop processing entity to the current lingo operation Allow processing time to be sent to the next hop processing entity; or process the current lingo operation according to the expected processing time of the current session operation; or schedule the current linger operation within the maximum allowed processing time.

The flow of the second embodiment of the session processing method of the present invention is shown in Figure 4, which shows the process by which the next hop session processing entity sends its maximum allowed processing time for the current session operation:

Step 401: The session processing entity determines the maximum allowed processing time of the current session operation.

Specifically, the maximum allowable processing time of the current session operation is consistent with the manner described in the first embodiment of the session processing method of the present invention, and is not further described herein.

Step 402: Calculate a maximum allowed processing time of the next hop session processing entity for the session operation. The current session processing entity may calculate the maximum allowed processing time of the next hop session processing entity for the current tongue operation according to the maximum allowed processing time, the actual processing time, and the message communication delay time of the current session operation.

The maximum allowable processing time of the session processing entity for the session operation, denoted as, should be not less than the sum of the following three periods: the processing time of the session operation before the session processing request message is sent to the next hop session processing entity. , is tl; the processing time of the session operation after receiving the session processing success message of the next hop session processing entity, recorded as t2; sending the session processing to the next hop session processing entity The processing time between the request message and the receipt of the next hop session processing entity for the session operation processing success message is recorded as t3, that is, t0 ≥ t1 + t2 + t3. The above t3 further includes: a communication delay of sending a session processing request message to the next hop session processing entity, denoted as t4; a communication delay of the next hop session processing entity sending the session operation processing success message, recorded as t5; The actual processing time of the session processing entity for the session operation is denoted by t, that is, t3=t4+t5+t. Therefore, according to the above two equations, t ≤ t0 - tl - t2 - t4 - t5.

Where t2 can be obtained by averaging the actual usage time of the most recently processed multiple tongue operations; the communication delay can be obtained by testing, for example, for a communication protocol defining a set of keep-alive messages, the current processing entity The next hop processing entity sends a message, and the next hop processing entity sends a response message to the current processing entity in a short time after receiving the message, for the current processing entity, from sending the message to receiving the response message. The time, denoted as t6, t6 can be regarded as the sum of t4 and t5 above, so the maximum allowable processing time of the next hop session processing entity for the session operation takes the maximum value of the above t, that is, t = t0 - tl - t2 - t6 When t4 and t5 are relatively small, t6 can be ignored, and t = t0 - tl - t2 is further simplified; of course, it can be further simplified that t = t0 when t1 and t2 are small. The above simplified calculation method can be selected according to the actual situation at various times.

Step 403: Send the calculated maximum allowed processing time to the next hop session processing entity. A specific application flow of the second embodiment of the session processing method of the present invention is shown in FIG. 5, which includes four entities: UE, AF, SPDF, and x-RACF:

Step 501: The UE sends a service request to the AF, where the maximum allowable processing time indicating that the session is established is 100 seconds.

Step 502: After receiving the service request of the UE, the AF sends an authorization request to the SPDF. The session establishment included in the authorization request sent to the SPDF is assumed to be 10 seconds due to the AF itself processing and communication for the service request. The maximum allowable processing time is 90 seconds.

Step 503: After receiving the authorization request of the AF, the SPDF sends a resource request to the x-RACF. Since the SPDF itself takes a certain time to process and communicate the authorization request, and assumes 15 seconds, the resource request is sent to the x-RACF. The maximum allowable processing time for session operations contained in is 75 seconds.

Step 504: After the x-RACF receives the resource request, the resource allocation is performed for the session operation, and the x-RACF should complete the tongue establishment within the maximum allowable processing time of 75 seconds.

Step 505: When the x-RACF completes the tongue establishment within 75 seconds, the resource request is returned to the SPDF. Successful response; When the x-RACF does not complete the session establishment within 75 seconds, a resource request failure response is returned to the SPDF.

According to the method embodiment of the present invention, the x-RACF can also flexibly schedule session operations within a maximum allowable processing time of 75 seconds. For example, in the first 30 seconds, x-RACF cannot allocate sufficient resources for the session, then x -RACF does not reject the establishment of the session, but may allocate resources for the remaining 45 seconds, that is, as long as the resource allocation is successful at any time within 75 seconds, the session can be established.

The flow of the third embodiment of the session processing method of the present invention is shown in Fig. 6, which shows the process of processing the current session operation based on the estimated processing time of the current session operation:

Step 601: The current processing entity determines the maximum allowed processing time of the current tongue operation. Specifically, the maximum allowable processing time of the current session operation is consistent with the manner described in the first embodiment of the session processing method of the present invention, and is not further described herein.

Step 602: Determine an estimated processing time for the session operation.

The estimated processing time of the tongue operation includes the waiting time and the necessary processing time for the session operation. The waiting time is further divided into the time to wait for available session resources and the response time to wait for the end of the next hop session processing entity to return.

Among them, for the same type of operation, the necessary processing time is relatively close, so the necessary processing time of the current session operation can be estimated by the processing time of other similar session operations that have been completed. For example, the actual processing time of the last 100 identical session operations is recorded, and the calculated average value is taken as the estimated necessary processing time for the current tongue operation.

The time for waiting for available session resources is because the current session operation cannot obtain sufficient resources, so it is necessary to wait for other session operations to release the session resources before obtaining sufficient resources. Therefore, the current processing entity needs to determine which session resources required for the current session operation are occupied by the tongue operation, and the remaining time of the estimated duration of the session operations determined at the time of establishment, and determine according to the remaining time. The remaining time corresponding to which operation can satisfy the current session operation to obtain sufficient session resources, which is the time to wait for available session resources. For example, suppose the current tongue needs to occupy the 25M downlink bandwidth on the transmission path A, and the path A has a total of 50M downlink bandwidth. Currently, the tongue 1 occupies 10M bandwidth, and the tongue 2 occupies 10M bandwidth. Occupies 20M bandwidth, and Session 1 has an estimated duration of 20 seconds left, Session 2 There are still 25 seconds left in the expected duration, and there are 30 seconds left in Session 3's expected duration. Therefore, since only 10M idle downlink bandwidth remains on the path A, the current resource requirement of the current operation cannot be satisfied. After the session 1 with the shortest expected duration is released, the path A will have 20M idle downlink bandwidth. However, the session resource requirement of the current session operation is still not satisfied; after the session 2 with the second shortest expected duration is released, the path A will have 30M idle downlink bandwidth, which can satisfy the current 25M session resource. Demand. Therefore, the time that the current session operation waits for available session resources is the estimated duration of the current remaining session 2, which is 25 seconds.

The response time of waiting for the next hop session processing entity to return to the processing end may be calculated by using the expected processing time sent by the next hop session processing entity to the current processing entity; the current processing entity has multiple next hops. When the session processing entity, the latest expected processing time can be used as the calculation time to wait for the response time of the processing returned by the next hop session processing entity. For example, the current session processing entity has three next hop session processing entities, namely entity 1, entity 2, and entity 3. The estimated processing time for the current session processing entity to receive the session operation of entity 1 at 00:00:00 is 30 seconds, that is, entity 1 expects to complete the session operation processing at 00:00:30; the current session processing entity is at 00:00:10 The estimated processing time of receiving entity 2 is 25 seconds, that is, entity 2 expects to complete the session operation processing at 00:00:35; the current processing time of the current session processing entity receiving entity 3 at 00:00:15 is 5 seconds, that is, Entity 3 expects to complete the session operation processing at 00:00:20. Therefore, the response time for all next-hop session processing entity return processing ends should be 00:00:35, waiting for all next-hop session processing entities relative to the latest return response time, ie 00:00:20 The response time for the return processing end is expected to be 15 seconds.

Step 603: Determine whether the difference between the estimated processing time and the maximum allowed processing time exceeds a threshold, and if yes, execute step 604; otherwise, execute step 605.

The threshold value is a preset time value according to the session processing, and the value may be an integer. For example, the threshold is set to 10 seconds, the maximum allowable processing time is 50 seconds, and when the estimated processing time is 50 seconds, the two times are The difference is 0 seconds, less than the threshold, allowing processing of the current tongue operation; when the expected processing time is 30 seconds, the difference between the above two times is minus 20 seconds, which is also less than the threshold, allowing the session The operation is processed. When the expected processing time is 70 seconds, the difference between the two times is 20 seconds. If the processing time is greater than the threshold, the current session operation is not processed.

Step 604: End the processing of the tongue operation and end the current flow. If the difference between the current estimated processing time and the maximum allowed processing time exceeds the preset threshold, the current session operation will not be processed.

Step 605: Processing the tongue operation within the maximum allowable processing time, ending the current flow. Further, in the foregoing embodiment 3, the current session processing entity may also feed back the estimated processing time to the user by means of text, voice or video, and the user decides whether to continue processing the current tongue operation according to the estimated processing time. Alternatively, the current processing entity sends the expected processing time to its previous hop session processing entity, and the last hop session processing entity determines whether to continue processing the session operation according to the estimated processing time. Through the foregoing embodiment 3, the session processing entity and the user can know the session prediction processing time, and select whether to cancel the processing of the current session operation according to the expected processing time, thereby avoiding wasting the user operation due to the inability to complete the processing for a long time. The processing resources of the time and session processing entity effectively improve the user's network experience.

A specific application flow of the third embodiment of the above-described session processing method of the present invention is shown in the figure, which includes five entities: UE, AF, SPDF, x-RACF1 and X-RACF2:

Step 701: The UE sends a service request to the AF.

Step 702: The AF sends an authorization request to the SPDF.

Step 703: The SPDF sends a resource request to the x-RACF1.

Step 704: The SPDF sends a resource request to the X-RACF2.

Step 705: The x-RACF1 sends a temporary resource request response to the SPDF, where the response includes x-RACF1 and the delay of establishing the session is 60 seconds.

Step 706: X-RACF2 sends a temporary resource request response to the SPDF, where the request response includes

X-RACF2 is expected to have a session latency of 80 seconds.

Step 707: The SPDF is based on the expected session establishment delay returned by x-RACF1 and X-RACF2 and the processing time and communication delay of the SPDF itself for the session operation, etc., and the estimated session establishment delay of the SPDF is 95 seconds, and is directed to the AF. Returns an authorization temporary response.

Step 708: After the AF receives the authorization temporary response, according to the establishment delay of the expected session operation in the response, the time and communication delay of the AF itself processing the session operation, etc., the establishment delay of the AF predicted session is 105 seconds. And return a business temporary response to the UE.

Step 709: After receiving the service temporary response, the UE obtains an estimated session establishment delay of the AF of 105 seconds, and assumes that the maximum allowable processing time of the current user is 60 seconds, and the expected delay and the maximum allowed position. If the difference of the processing time is 55 seconds greater than the preset threshold of 30 seconds, the user cancels the current session operation and sends a service revocation message to the AF.

Step 710: After receiving the service revocation message, the AF sends an authorization revocation message to the SPDF.

Step 711: After receiving the authorization revocation message, the SPDF sends a resource revocation message to the x-RACF1. Step 712: The SPDF sends a resource revocation message to the X-RACF2.

The flow of the fourth embodiment of the session processing method of the present invention is as shown in Fig. 8. This embodiment shows the process of scheduling the current tongue operation within the maximum allowable processing time:

Step 801: The session processing entity determines the maximum allowed processing time of the current session operation.

Step 802: Determine the remaining processing time of the maximum allowable processing time of the current session operation. If the session operation corresponds to the smaller remaining processing time, go to step 803. If the session operation corresponds to the larger remaining processing time, go to step 804.

The current processing entity may process multiple operations at the same time, so the processing entity can flexibly schedule each session operation according to the remaining processing time of the maximum allowed processing time of each current session operation. In addition to judging the remaining processing time of the maximum allowed processing time, the session processing entity may also schedule the operation of the tongue in combination with other factors, which may include the urgency of the operation, the importance of the session operation, the service classification of the session operation, and the like. .

Step 803: The session operation corresponding to the minimum remaining processing time is scheduled to be processed, and step 805 is performed.

The current session processing entity preferentially processes the session operation corresponding to the smaller remaining processing time according to the remaining processing time of the maximum allowed processing time of each session operation. The remaining processing time here is the maximum allowed processing time minus the processed time of the session operation, and the processed time further includes the time to wait for the session operation to be scheduled.

For example, the session processing entity processes session 1 at 10:00:00, and the maximum allowed processing time of session 1 is 20 seconds; the session processing entity processes session 2 at 10:00:03, and the maximum allowable session 2 The processing time is 10 seconds.殳 The current time is 10:00:05, then the remaining processing time of session 1 maximum allowed processing time is 15 seconds, the remaining processing time of session 2 maximum allowed processing time is 8 seconds, and session 1 and session 2 are currently waiting for scheduling. The state of processing, then the session The entity preferentially schedules session 2 for processing. It is assumed that the session processing entity processes each session for 5 seconds. If the session is not processed according to the remaining processing time, but the session 1 is processed first according to the session establishment sequence, the maximum allowable processing of the session 2 when the session 1 is processed is completed. The remaining processing time of the time has been processed first, and the remaining processing time of the maximum allowed processing time of the session 1 is 10 seconds, which is enough to complete the processing of the session 1. Therefore, the scheduling method improves the pair. The success rate of session processing.

Step 804: Pause or abandon the processing of the session operation with the largest remaining processing time.

The current session processing entity pauses or discards the session operation corresponding to the larger remaining processing time according to the remaining processing time of the maximum allowed processing time of each session operation. In particular, when the session processing entity needs to suspend or abandon the processing of a part of the session operation due to CPU overload, insufficient storage space, or preemption of resources by the emergency session operation, the session operation corresponding to the larger remaining processing time is temporarily suspended or discarded. The remaining processing time here is the maximum allowed processing time minus the processed time of the session operation, and the processed time further includes the time at which the session operation waits for scheduling.

It should be noted that since the telecom-level session processing entities generally have a retransmission function, the session operation of the last hop session processing entity is suspended for the session operation that is suspended as needed, even if the session operation is discarded by the current session processing entity. The session operation may be resent to the session processing entity, causing the session processing entity to complete processing of the session operation within the maximum allowed processing time of the session operation.

Step 805: Determine whether the preset scheduling waiting time is exceeded. If yes, return to step 802. Otherwise, execute step 805.

The session processing entity can generally start a timer, and the timer period is a scheduling waiting time, and the session operation is re-scheduled after the timer expires. The situation that needs to be rescheduled includes the CPU overload of the processing entity, the current tongue operation cannot obtain enough resources, or the current session operation cannot check the policy rule of the entity through the session.

When the CPU of the session processing entity is overloaded, the session processing entity reschedules the session operation after the timer expires after the preset scheduling wait time is exceeded. For example, when the session processing entity receives a processing request for a session operation, the CPU of the session processing entity is already in a severe overload state. If the maximum allowable processing time of the session operation is 20 seconds, the session processing entity may follow the schedule. Waiting time, it is assumed that the session operation is scheduled and processed after a delay of 10 seconds to alleviate the processing pressure of the current CPU and provide effective overload protection for the session processing entity. Similarly, although the session processing entity only delays the processing time of one session operation, it has little effect on reducing the processing pressure of the session processing entity CPU. However, if the processing entity waits for the scheduling waiting time, the current multiple tongue operations are delayed. After processing for a period of time, the CPU processing pressure of the session processing entity can be significantly reduced from the overall effect. Of course, if the CPU is still overloaded after the rescheduling session operation, the session processing entity may choose to directly process the session operation regardless of whether the CPU is overloaded, or may preferentially wait for a timer period of waiting for a timer repeatedly, and then schedule the current session operation according to the judgment result. Until the session operation is processed successfully or the processing time exceeds the maximum allowed processing time.

When the session operation fails to obtain sufficient session resources, the session processing entity reschedules the session operation after the timer expires after the preset scheduling wait time expires. The session resources here include storage space, network resources, link bandwidth, IP address, port, etc., although these session resources are shared by multiple processing entities, but when the operation of the session resources is released, the other resources are released. Session operations that share the session resource can use these session resources to complete the processing of the session operation. Certainly, when allocating network resources for the session operation, the session processing entity may allocate sufficient network resources for the session operation in one scheduling process, or allocate a part of network resources for the session operation each time the scheduling is performed. The accumulation of secondary schedules ultimately allocates sufficient session resources for the session operation.

When the current session operation cannot be checked by the policy rule of the session processing entity, the session processing entity reschedules the session operation after the timer expires after the preset scheduling wait time expires. The policy rules here include: user-signed bandwidth limit, online session limit, and online session limit for the service. It should be noted that although the current session operation may not be able to pass the policy rule check of the session processing entity, after the scheduling wait time elapses, other session operations end processing, and the session operation may be checked by the policy rule. For example, the session processing entity has an online session operand limit of 1000. Assuming that there are already 1000 online session operations, the new session operation cannot pass the check of the policy rule, because if the session operation is established again, online The number of sessions has reached 1001, which exceeds the limit of the policy rule. However, after a period of time (this time is less than the maximum allowable processing time of the session to be established), if one session operation ends, the current online session operand becomes 999. After the waiting time expires, the session operation can be established by rescheduling. Corresponding to an embodiment of the session processing method of the present invention, the present invention also provides an embodiment of a session processing system.
