Embodiments of the invention

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

For the fourth generation communication system (4G), the 3rd Generation Partnership Project (3GPP) standard working group defines the LTE system wireless subsystem and the EPS core network subsystem.

Figure 1 shows the entire LTE and EPS system architecture. As shown in FIG. 1 , the radio subsystem part of the LTE system mainly includes an Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The EPS core network subsystem part, also known as the Evolved Packet Core (EPC). Under the system architecture, EPC not only supports users to access from LTE, but also supports users from GSM EDGE radio access network (GERAN, GSM EDGE radio access network) and Universal Terrestrial Radio Access Network (UTRAN). Access.

In the EPC, a Home Subscriber Server (HSS), a Mobility Management Entity (MME), a Serving Gateway (S-GW), and a PDN Gateway (P-GW) are included. Serving GPRS Support Node (SGSN) (not shown in Figure 1) and Policy and Charging Rule Fuection (PCRF). among them,

HSS: is the permanent storage location of the user's subscription data, located in the home network signed by the user;

MME: is the location where the user subscription data is stored in the current network, responsible for terminal-to-network non-access stratum (NAS, Non-Access Stratum) signaling management, user idle mode tracking and paging management functions, and bearer management;

S-GW: is a gateway from the core network to the wireless system, and is responsible for the user plane bearer of the terminal to the core network, the data buffer in the terminal idle mode, the function of initiating a service request by the network side, the legal eavesdropping and the packet data routing and forwarding function;

P-GW: is the gateway of the EPS and the external network of the system, and is responsible for functions such as IP address allocation, charging function, packet filtering, and policy application of the terminal;

SGSN: is a service support point for GERAN and UTRAN users to access the EPC network. It functions similarly to the MME and is responsible for user location update, paging management, and bearer management.

PCRF: Provides policy control and charging rules for the Policy and Charging Enforcement Function (PCEF).

After the user equipment (UE, User Equipment) accesses the EPS network, the network creates a suitable Public Data Network (PDN) connection for the UE and assigns an IP address to the UE, so that the UE can Send and receive IP packets. In the LTE and EPS architecture, to implement voice services, a voice over LTE (VoLTE, Voice Over LTE) service system is required. Typically, the IP Multimedia Subsystem (IMS) provides voice communication, video communication, media messaging and other services based on IP communication, and is the first choice for implementing LTE voice services. Moreover, on the IMS, not only a voice session, a video session, a short message service but also a rich type of third-party data type service, such as multi-party video sharing, can be implemented.

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.

The service triggering and control functions in the control layer are implemented by the Call Session Control Function (CSCF). The CSCF is divided into three types: P-CSCF, Inquiring Call Session Control Function (I-CSCF, Interrogating-CSCF) and S-CSCF.

The service layer is composed of a series of application servers (AS, Application Server), which can provide specific service services; the AS can be an independent entity or exist in the S-CSCF.

The control layer (S-CSCF) controls the service trigger according to the subscription information of the user, and calls the industry on the AS. Business, to achieve business functions.

Under the LTE and EPS system architecture, IMS relies on a specific PDN connection that supports IMS. Typically, the operator will define a specific APN (ie APN = "IMS") dedicated to the IMS to provide a PDN connection to the IMS.

In the EPS technology, when the UE is initially attached, the EPC creates a default PDN connection for the UE according to the default access point name (APN, Access Point Name) in the user subscription. The UE may initiate uplink IP data transmission by using the PDN connection, and receive downlink IP data sent by the remote end. Thereafter, the UE can also create a new PDN connection by using the corresponding APN request according to the service requirement.

When the UE no longer needs to use a certain PDN connection, the UE may activate the PDN connection by itself, and according to the request of the UE, the EPC releases the resources occupied by the corresponding PDN connection.

Currently, the end user can manually close the data connection through the menu interface through the terminal operation interface. Such an operation usually causes the UE to no longer send an IP packet to the network, or the UE automatically initiates a deactivation of the PDN connection request, so that the network releases the resources of the PDN connection.

However, this method of shutting down data services is too simple and it is difficult to meet the needs of users after implementing VoLTE. Users may wish to turn off certain Internet services, such as Internet access, but retain certain services (exempted services), such as some of IMS's services. In this case, it is necessary to selectively partially shut down the user's data service.

Based on this, 3GPP provides a method for partially closing user data, as shown in FIG. 2, the method includes:

201: The user partially turns off the data service;

202: The UE sends an Initial Attach or Tracking Area Update (TAU) message to the MME, and carries a partial shutdown data service indication.

203: After receiving the message, the MME sends a bearer modification request or a session establishment request to the P-GW through the S-GW.

The request carries part of the closed data service.

204: After receiving the request, the P-GW interacts with the PCRF to obtain a new part of the data service after the data service is closed. Policy Control and Charging (PCC, Policy Control and Charging) rules;

In other words, get a new filter rule.

205: After the downlink packet data arrives at the P-GW, the P-GW discards the data packet of the non-exempt service according to the PCC rule.

However, in the IMS service, part of the service is Exempt Services (A feature which when configured in the UE and the Core Network by the HPLMN and activated by the user prevents transport via PDN connections in 3GPP When accessing all IP packets except IP packets required by 3GPP PS Data Off Exempt Services), from the perspective of the P-GW, the signaling for all IMS services of the same UE is in the same bearer, and its quintuple (Source IP address, source port, destination IP address, destination port, protocol) is the same, so the P-GW is unable to distinguish the signaling of different services, so the above method is still not perfect in implementation.

Based on this, one solution is that the UE can notify the IMS network part to close the data service through the IMS layer registration or re-registration. As shown in FIG. 3, the solution includes the following steps:

301: The user chooses to close part of the data service;

302: The UE sends a registration or re-registration request to the P-CSCF, where the part of the closed data service indication is carried;

303: After receiving the request, the P-CSCF forwards the registration or re-registration request to the I/S-CSCF, where the partial data service indication is carried;

Here, after the P-CSCF first sends the I-CSCF request, the I-CSCF sends it back to the S-CSCF.

304: After receiving the request, the S-CSCF sends a 200 OK message to respond;

305: The subsequent IMS terminal call service (MT, Mobile Ternimating) arrives at the S-CSCF;

306: The S-CSCF judges whether to release according to whether it is an exempted service.

It should be noted that when the user activates the data service, the UE also initiates a similar process, where the registration message carries the activation data service indication.

For the caller (MO, Mobile Originating) service, that is, the service initiated by the UE. The request is blocked by the UE itself, and the network side mainly blocks the MT service.

Of course, in actual application, the network side can also block the MO service.

However, IMS registration or re-registration is a relatively resource-consuming process. In this process, a large amount of signaling is consumed, and in the registration, the authentication part also consumes a lot of processing power, especially when the UE frequently shuts down the data service, causing the network. heavy burden.

Then, how to enable the terminal to notify the IMS network with a small overhead when partially closing the data service.

Based on this, in various embodiments of the present invention, the S-CSCF obtains a service indication, the service indication is used to indicate that the UE part of the data service is closed, the service indication is acquired from the HSS or the SCC AS, and the UE service message is received. Determining whether the type of the received service message is an exempted service; according to the judgment result, performing a transmission control process on the received service message; or, after the SCC AS obtains the service indication from the HSS, receiving the UE service message; determining the received service message Whether the type is an exempted service; according to the judgment result, the received service message is sent to the control process; or the P-SCCF obtains the service indication; the service indication is used to instruct to close the part of the data service of the UE; The P-CSCF acquires the Rx session from the PCRF or obtains the Rx session from the PCRF; receives the UE service message; determines whether the type of the received service message is an exempt service; and according to the judgment result, the received service message The transmission control process is performed.

The data processing method in this embodiment is applied to the S-CSCF, as shown in FIG. 4, and includes the following steps:

Step 401: Obtain a service indication.

Here, the service indication is used to indicate that the UE part of the data service is closed, to trigger the S-CSCF to perform a transmission control process on the UE service message.

The service indication is obtained from an HSS or SCC AS (in the MT process, the SCC AS is the last device triggered by an initial filter rule (iFC)).

In actual application, when the service indication is obtained from the HSS, the implementation of this step may include:

Obtaining subscription data of the UE from the HSS; the subscription data includes the service indication;

Or,

Receiving the service indication sent by the HSS.

The subscription data of the UE is obtained from the HSS before the UE is not registered by the IMS. Receiving, by the UE, the service indication sent by the HSS when the IMS has already registered.

When the service indication is obtained from the SCC AS, the implementation of this step may include:

Receiving, by the iFC, the call corresponding to the service message to the SCC AS, and receiving the service indication sent by the SCC AS; the service indication sent by the SCC AS is the SCC The service indication obtained by the AS from the HSS.

Here, for iFC, multiple iFCs form an ordered list, which is downloaded from the HSS to the S-CSCF when it is registered. When the S-CSCF receives the service message, it will match the iFCs in order. If the match is successful, the service message will be forwarded to the AS specified in the corresponding iFC. After the AS finishes processing, it can be returned to the S-CSCF. May not return S-CSCF.

The receiving the service indication sent by the SCC AS includes:

Receiving a SIP message sent by the SCC AS; the SIP message carries the service indication.

Step 402: Receive the UE service message.

Here, in actual application, receiving the UE service message may be receiving a service message (MO service message) from the UE, or may be a service message (MT service message) sent to the UE. In other words, the solution provided by the embodiment of the present invention can be applied to an MO service message, and can also be applied to an MT service message.

Of course, in practical applications, the solution provided by the embodiment of the present invention is used for MT service messages.

Step 403: Determine whether the type of the received service message is an exempt service;

In actual application, it may be determined according to the exempt service list whether the type of the received service message is an exempt service.

Therefore, in an embodiment, the S-CSCF may obtain the exempt service list from the HSS in a standard IMS registration process, and then determine, according to the obtained exempt service list, whether the type of the received service message is an exemption. business.

In addition, in the actual application, the exempt service list can also be configured locally beforehand. Then, in this case, the exemption service is the same for all UEs.

Step 404: Perform transmission control processing on the received service message according to the judgment result.

In other words, the received service message is released or discarded.

Optionally, when the type of the received service message is an exempt service, the received service message is released; when the type of the received service message is not an exempt service, the received service message is discarded.

In an embodiment, the service indication may be further used to indicate that the UE data service is activated to trigger the S-CSCF to perform a transmission control process on the UE service message.

Correspondingly, the method may further comprise:

After the service indication is used to indicate that the UE data service is activated, and the UE service message is received, the S-CSCF releases the received service message.

Here, it should be noted that: the service indication is used to indicate that the scenario of activating the data service of the UE is applicable to the part of the data service after the UE has closed the data service, and the service indication is used when a part of the data service that has been closed needs to be activated. Instructing the UE to activate the data service.

The release means that the received service message is sent, so that the receiver can receive the service message.

Correspondingly, the method may further comprise:

And when the service indication is used to indicate that the UE data service is activated, and when the UE service message is received, the S-CSCF releases the received service message.

In an actual application, before the HSS sends a service indication to the S-CSCF, the method may further include:

When it is learned that the UE closes part of the data service or activates the data service, the MME sends the service indication to the HSS.

In an embodiment, before the SCC AS sends a corresponding indication to the S-CSCF, the method may further include:

The SCC AS sends a query request to the HSS;

The HSS returns the service indication to the SCC AS according to the query request.

The method may further include: before the returning the service indication to the SCC AS, the method may further include:

The HSS acquires the service indication from an MME.

Optionally, when the UE is notified to close part of the data service or activate the data service, the MME sends the service indication to the HSS;

or,

The HSS sends a query request to the MME; the MME returns the service indication to the HSS according to the query request.

It should be noted that the specific processing procedure of the S-CSCF has been detailed above, and details are not described herein again.

Similar to the S-CSCF, in practical applications, the SCC AS can also control the traffic of business data.

Based on this, the embodiment of the present invention further provides a data processing method, which is applied to an SCC AS (in the MT process, the SCC AS is the last device triggered by the iFC), wherein multiple iFCs form an ordered list, which It is downloaded from the HSS to the S-CSCF when it is registered. When the S-CSCF receives the service message, it will match the iFCs in order. If the match is successful, the service message will be forwarded to the AS specified in the corresponding iFC. After the AS finishes processing, it can be returned to the S-CSCF. May not return S-CSCF.
