Description

Resource sharing processing method, device and P-CSCF

Technical field

The present invention relates to the field of communications, and in particular to a resource sharing processing method and apparatus, and a proxy call session control function (Proxy-CSCF, abbreviated as P-CSCF).

Background technique

The IP Multimedia Core Subsystem (IMS) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP) to build an open and flexible service. The environment supports multimedia applications and provides users with rich multimedia services. In the IMS service system, the control layer and the service layer are separated. The control layer does not provide specific services, and only provides necessary triggering, routing, and accounting functions to the service layer.

FIG. 1 is an IMS basic architecture defined by the 3GPP in the related art. The service triggering and control function in the control layer is completed by the Call Session Control Function (CSCF). The call session control functions are divided into three types: P-CSCF, Interrogating-CSCF (I-CSCF) and Serving-CSCF (S-CSCF).

The business layer is composed of a series of Application Servers (ASs), which can provide specific business services. The control layer (S-CSCF) controls the service trigger according to the subscription information of the user, and invokes the service on the AS to implement the service function.

An end-to-end device in a session is called a user equipment (User Equipment, UE for short) and is responsible for interacting with users. Some UEs have multiple ways to access the network, including packet switching through 3GPP (Packet Switch, PS for short). The domain access network accesses the network through other non-3GPP PS domains.

The IMS reflects the service level, and the network resources required for the final service are ultimately provided by the 3GPP PS network or the non-3GPP PS network. 2 is a schematic diagram of a Policy and Charging Control (PCC) architecture defined by the 3GPP. IMS uses PCC to implement the use of the underlying network resources.

Policy and Charging Rules Function (PCRF) is used to formulate Quality of Service (QoS) and charging policies for services using network resources. The PCRF formulating the control strategy needs to be combined with the application function (Application Function, referred to as AF. In the IMS system). The P-CSCF is an AF (A) received service information, user subscription information received from a User Profile Repository (SPR), and a policy configured by the operator. The PCRF sends the control policy for the service to the Policy and Charging Enforcement Function (PCEF) or the Bearer Binding and Event Report Function (BBERF). At the same time, the PCRF can subscribe to the bearer layer related events to the PCEF and/or the BBERF to sense in time when the bearer layer occurs, and change the control strategy. In addition, the PCEF and the Traffic Detection Function (TDF) can perform application detection and control functions according to the PCC rules (PCEF) or Application and Detection Control (ADC) rules (TDF) delivered by the PCRF. .

FIG. 3 is a flowchart of the interaction between the calling side P-CSCF and the PCRF in the process of establishing a IMS video telephony session in the related art to implement network resource reservation. As shown in FIG. 3, the process includes the following steps:

Step 301: The UE interacts with the network to establish an IP-CAN session.

Step 302: The P-CSCF receives the SDP offer carried in the SIP message, where the SDP parameter defined by the calling UE is carried. In addition, the message is also carried as a dialog identifier (represented as dialog identifier 1);

Step 303: The P-CSCF forwards the SDP offer to the terminating side.

Step 304: The P-CSCF receives the negotiated SDP response from the terminating side;

Step 305: The P-CSCF root SDP response acquires related media information, such as an IP address, a port number, a media category, a QoS requirement, and the like. The P-CSCF sends a Diameter AAR message to the PCRF to request resource reservation;

Step 306: The PCRF saves the received service information and performs session binding.

Step 307: The PCRF returns a Diameter AAA message to the P-CSCF.

Step 308: The P-CSCF forwards the SDP parameters to the UE.

Step 309: The PCRF makes a policy decision according to the received session information, and formulates a PCC rule. There may be more than one PCC rule developed by the PCRF. For video telephony, the QoS required for video and voice is usually different. Therefore, the PCRF can separately formulate a PCC rule for the video stream and the voice stream. For example, the QC of the PCC rule corresponding to the audio stream is 1, the GBR and the MBR are 23 kps, and the video stream The PCC rule has a QCI of 2, and the GBR and MBR are 700 kps. The PCC rule represents one or a set of PCC rules that the PCRF makes for this IMS session. Normally, the gating of the PCC rule is not yet open at this time;

Step 310: The PCRF sends a RAR message to the PCEF, where the message carries a PCC rule.

Step 311: The PCRF returns an RAA message to the P-CSCF.

Step 312: The PCEF installs and executes the PCC rule to complete the resource reservation of the session. For example, the GBR/MBR for voice bearer is 23kps, and the GBR/MBR for video bearer is 700kps.

4 is a flow chart of the PCRF making a decision, opening a gate, and allowing an authorized service to use the resource allocated thereto according to the process in FIG. 3 in the related art. As shown in FIG. 4, the process includes the following steps:

Step 401: The P-CSCF receives a 2xx success message.

Step 402: The P-CSCF sends a Diameter AAR message to the PCRF, requesting to open the gating of the service.

Step 403: The PCRF updates the flow state information of the affected PCC rule, and opens the gating, that is, the PCRF opens the two-way gating of the PCC rule, the UE can send data to the peer end, and the peer end can also send data to the UE.

Step 404: The PCRF returns an AAA message to the P-CSCF.

Step 405: The P-CSCF forwards the 2xx success message to the UE.

Step 406: The PCRF sends a Diameter RAR message to the PCEF, and carries the updated PCC rule.

Step 407: The PCEF returns an acknowledgement message to the PCRF.

Step 408: The PCEF updates the PCC rules and opens the gate.

In IMS, one UE can have multiple sessions. FIG. 5 is a flowchart of a related art IMS, initiating a call after maintaining a current session. As shown in FIG. 5, UE-A and UE-B have an active active session D1, and the network allocates the session to the session. Resources and open the gates. At this time, in step 501, UE-A holds the session with UE-B (Hold), and then in step 502, UE-A initiates a session D2 establishment procedure to UE-C. This process is the same as the process of Figure 3 + Figure 4. At this point, at this time, the network session D2 allocates resources and opens the gate. However, resources allocated to session D1 (between UE-A and UE-B) are not released. Thus, although UE-A can only have one active session, all sessions occupy the resources of the network, even if it is an inactive session.

6 is a flow chart of call waiting in the related art IMS. As shown in FIG. 6, another scenario is shown. UE-A and UE-B have an active session D1, and the network allocates resources to the session. And open the gate. At this time, in step 601, the UE-C initiates a session D2 establishment request to the UE-A. This process is the same as the process of Figure 3. At this time, the network session D2 is allocated resources at this time, but the gating is not turned on. Although UE-A can only have one active session, all sessions occupy the resources of the network, even if it is an inactive session.

For a user, when there are services such as hold, call waiting, and conference, there is only one active session at any time, but the bearer resources of other held sessions are not released. Causes resources on the PGW to be occupied. To this end, 3GPP defines new technologies that enable the underlying network resources to be shared. As shown in step 305 of FIG. 3, the P-CSCF notifies which sessions are shared resources in the message to the PCRF, and the PCRF notifies the PCEF that the sessions share the underlying bearer resources.

However, the problem is that the current P-CSCF is only the first access point for the UE to access the IMS network, and is a SIP proxy, which is the service information of no user. It cannot understand the business relationship between different sessions of the UE, and it cannot be judged whether only one of these sessions is activated. It is inaccurate to judge the trigger by the P-CSCF. For example, in some occasions of an emergency call, you need to hear the media of 2 calls at the same time.

Therefore, in the related art, since there are a plurality of services at the same time, there may be only one or a plurality of activations. If the judgment cannot be made correctly, the resources cannot be shared correctly, and thus there is a problem of waste of resources.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In this embodiment, a resource sharing processing method is provided. FIG. 7 is a flowchart of a resource sharing processing method according to an embodiment of the present invention. As shown in FIG. 7, the process includes the following steps:

Step S702, receiving the concurrency relationship information sent by the multimedia telephony application server MMTEL AS and/or the user equipment UE for identifying two or more session services held by the UE, it should be noted that the session is The service can be a voice service, a video service, or a combination of the two;

Step S704, processing resource sharing between two or more session services held by the UE according to the received concurrent relationship information.

According to the above steps, according to the concurrent relationship information delivered by the MMTEL AS and/or the user equipment UE that accurately grasps the concurrent relationship information between the two or more session services held by the UE, according to the accurate session service The concurrent relationship information processes the resource sharing between the session services. Compared with the related technology, since there are multiple services at the same time, there may be only one or a plurality of activations. If the resources cannot be correctly judged, the resources cannot be correctly shared, which not only effectively solves the problem of the above-mentioned resource waste in the related technologies, but also achieves the effect of accurately triggering the sharing of the session service resources and greatly improving the utilization of the network resources.

When the resource sharing between two or more session services held by the UE is processed according to the received concurrent relationship information, different processing manners may be adopted, for example, according to the received concurrent relationship information. Different operations are performed differently, as exemplified below.

For example, the default configuration is to perform resource sharing on two or more session services held by the UE, and the concurrent relationship information sent by the MMTEL AS and/or the UE is used to identify that multiple session services are activated. In the case of the first concurrent relationship information, a resource reservation operation for non-resource sharing between two or more session services held by the UE is performed according to the first concurrent relationship information. That is, when the default configuration is to always perform resource sharing, when the MMTEL AS and/or the concurrent session information that is sent by the UE and the multiple session services are activated, it is determined that resource sharing is not performed between the multiple session services, that is, Resource allocation is performed according to the normal traditional resource reservation method.

For example, in the default configuration, the conditional triggering is used to trigger resource sharing for two or more session services held by the UE, and the concurrent relationship information sent by the MMTEL AS and/or the UE is only one identifier. In the case where the session service is the activated second concurrent relationship information, according to the received second concurrent The relationship information triggers resource sharing between two or more session services held by the UE. That is, when the default configuration is not to share resources, it is determined that between the two or more session services, when the MMTEL AS and/or the UE sends only one session service to be activated concurrent relationship information. Perform resource sharing.

It should be noted that the request information received to the concurrent relationship information may be active or passive. For example, when the concurrent relationship information is mainly requested, the MMTEL AS and/or the UE may be used to receive the information. Before identifying the concurrent relationship information between two or more session services held by the UE, the request information for requesting the concurrent relationship information is sent to the MMTEL AS and/or the UE. It is also possible to use the MMTEL AS and/or the UE to periodically and actively transmit the concurrent relationship information, that is, the network element that triggers the resource sharing operation passively receives the concurrent relationship information.

FIG. 8 is a flowchart of a method 2 of resource sharing processing according to an embodiment of the present invention. As shown in FIG. 8, the process includes the following steps:

Step S802, determining concurrent relationship information between two or more session services held by the user equipment UE;

Step S804, the determined concurrent relationship information is sent to the proxy call session control function entity P-CSCF, where the concurrent relationship information is used by the P-CSCF for resources between two or more session services held by the UE. Share for processing.

Through the foregoing steps, the concurrent relationship information between the two or more session services held by the UE is determined, and the concurrent relationship information is sent to the P-CSCF, so that the P-CSCF can be based on the accurate session service. The concurrent relationship information is used to process the resource sharing between the session services. Compared with the related technology, since there are multiple services at the same time, only one is activated, and other resources are not released, which not only effectively solves the related technologies. The above-mentioned problem of waste of resources has reached the goal of accurately triggering the sharing of session service resources and greatly improving the utilization of network resources.

Correspondingly, before transmitting the determined concurrent relationship information to the P-CSCF, the request information for requesting the concurrent relationship information sent by the P-CSCF may also be received.

The scheme will be described below.

The Multimedia Tel Apply Server (MMTEL AS) is the control point of the IMS service. It can understand the service information. During the call, the MMTEL AS provides the concurrent relationship between the sessions (whether only one can be activated, Or, whether the resources can be shared, the P-CSCF determines whether the PCC process of resource sharing can be triggered according to the relationship between the sessions. It should be noted that it can also be configured on the P-CSCF to forcibly share the resources of the user. This can effectively avoid the traffic of the network. For example, the configuration can share resources by default on the P-CSCF, and only resources cannot be shared. When the notification message is sent by the network, resources cannot be shared between the two services, so that the resource reservation process of non-resource sharing is performed.

Preferably, the MMTEL AS can be notified by the P-CSCF, which can handle the resource sharing capability; the UE can also carry related information in the call signaling.

In the following preferred embodiments and preferred embodiments, the MMTEL AS (TAS) sends an indication that the P-CSCF receives the session activation relationship between the sessions, the concurrent relationship, and the resource sharing relationship, all referring to the same concept.

The invention will now be described with reference to the drawings and embodiments.

FIG. 20 is a flowchart of a call waiting service when a UE-A is in a session with a UE-B according to an embodiment of the present invention. As shown in FIG. 20, the process includes the following steps: wherein the UEs UE-A and UE-B have An activation session D-1.

Step 2001: The UE-C decides to initiate a call to the UE-C, and the UE-C sends an INVITE message, and the message arrives at the TAS;

Step 2002: The TAS determines that the session D-2, D-1 is not activated at the same time;

Step 2003: The TAS forwards the INVITE message to the UE-A via the I/S-CSCF, where the activation relationship (concurrency relationship/resource sharing relationship) between the sessions D-2 and D-1 and the CW indication are carried;

Step 2004: UE-A sends an SPD response to the P-CSCF;

Step 2005: The P-CSCF determines that D-2 and D-1 are not activated at the same time according to the stimulating relationship between the received sessions, and may apply resource sharing.

Step 2006: The P-CSCF triggers the underlying resource sharing through the PCC process;

Step 2007: The P-CSCF forwards the SPD response to the UE-C via the I/S-CSCF.

FIG. 21 is a flowchart of a UE-A initiating session establishment to a UE-C after a hold and a UE-B session according to an embodiment of the present invention. As shown in FIG. 21, the process includes the following steps: where the user UE- A and UE-B have an active session D-1. At this time, UE-A actively sends an activation relationship between sessions.

Step 2101: User UE-A keeps session D-1;

Step 2102: UE-A decides to initiate a call to UE-C.

Step 2103: UE-A sends an INVITE message, and the message arrives at the P-CSCF. UE-A inserts an activation relationship (concurrent relationship/resource sharing relationship) between sessions D-1 and D-2 in the message;

Step 2104: The P-CSCF forwards the INVITE message to the UE-C to the I/S-CSCF.

Step 2105: After receiving the call, the UE-C sends back an SDP response. The message arrives at the P-CSCF via the TAS, I/S-CSCF;

Step 2106: The P-CSCF determines, according to the aggressive relationship between the received sessions, that D-2 and D-1 are not activated at the same time, and resource sharing may be applied.

Step 2107: The P-CSCF triggers the underlying resource sharing through the PCC process.

Step 2108: The P-CSCF forwards the SPD response to the UE-A.

FIG. 22 is a flowchart of a P-CSCF being pre-configured to always perform resource sharing according to an embodiment of the present invention. At this time, UE-A initiates session establishment to UE-C after holding and UE-B sessions, as shown in the figure. As shown in FIG. 22, the flow includes the following steps: Users UE-A and UE-B have an active session D-1.

Step 2201: User UE-A maintains session D-1;

Step 2202: UE-A decides to initiate a call to UE-C.

Step 2203: UE-A sends an INVITE message, and the message arrives at the P-CSCF.

Step 2204: The P-CSCF forwards the INVITE message to the UE/C to the I/S-CSCF. Optionally, the P-CSCF inserts an indication that the configuration itself always supports session resource sharing into the INVITE message;

Step 2205: After receiving the call, the UE-C sends back an SDP response. The message arrives at the TAS;

Step 2206: If the TAS determines that the session D-2 and the D-1 are not activated at the same time, no special processing is performed. In this scenario, TAS determines that session D-2, D-1 may be activated at the same time;

Step 2207: The TAS forwards the SPD response to the P-CSCF via the I/S-CSCF, where the relationship between the conversations D-2 and D-1 may be simultaneously activated (concurrency relationship/resource sharing relationship);

Step 2208: The P-CSCF determines that D-2 and D-1 may be activated at the same time according to the stimulating relationship between the received sessions, and the resource sharing cannot be applied.

Step 2209: The P-CSCF triggers the underlying regular resource reservation (non-shared) through the PCC process;

Step 2210: The P-CSCF forwards the SPD response to the UE-A.

In the scenario where the P-CSCF is pre-configured to always perform resource sharing, the service flow shown in FIG. 19, 20 is similar to that in FIG. 22, and the P-CSCF is pre-configured to always perform resource sharing, if the MMTEL AS finds that the sessions are simultaneously When activated, the P-CSCF is notified, and the P-CSCF does not perform resource sharing processing.
