Description

Packet switching data service processing method, terminal, MME and PGW

Technical field

The present invention relates to the field of communications, and in particular, to a method, a terminal, an MME, and a PGW for processing a packet switched PS data service.

Background technique

For the 4th Generation mobile communication technology (4G), the 3rd Generation Partnership Project (3GPP) standard working group defines Long Term Evolution (LTE). System wireless subsystem, Evolved Packet System (EPS) core network subsystem.

FIG. 1 is a schematic diagram of the architecture of an LTE/EPS system in the related art. The LTE part of the wireless subsystem 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) and Universal Terrestrial Radio Access Network (Universal Terrestrial Radio Access Network). Referred to as UTRAN).

The EPC packet core network includes a Home Subscriber Server (HSS), a Mobility Management Entity (MME), a Serving Gateway (S-GW), and a packet. A data network gateway (PDN Gateway, P-GW for short), a Serving GPRS Support Node (SGSN), and a Policy and Charging Enforcement Function (PCRF), where:

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

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

The S-GW is a gateway of 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;

The P-GW is an evolved packet domain system (EPS) and a gateway of 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.

The 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.

The PCRF is responsible for providing policy control and charging rules to the PCEF.

After the user equipment (User Equipment, UE for short) is connected to the EPS network, the network creates a suitable Public Data Network (PDN) connection for the UE and allocates an Internet protocol to the UE. The Internet Protocol (referred to as IP) address, so that the UE can use the IP address to send and receive IP data packets. In the LTE/EPS architecture, voice services are implemented, and the LTE Voice (VoLTE) 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 subsystem, 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.

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

Under the related EPS technology, when the UE is initially attached, the EPC core network creates a default PDN connection for the UE according to the default access point name (Access Point Name, APN for short) in the user subscription. The UE can initiate uplink IP data transmission using the PDN connection, The downlink IP data sent by the remote end (eg, the application server) may be received on the PDN connection. Then, if the UE needs to create another PDN connection according to the service requirement, it will use the corresponding APN request to create a new PDN connection according to the service requirement. Within a PDN connection, the UE or the network can create multiple different bearers (EPS bearers), each bearer having different bearer parameters, such as: QoS Class Identifier (QCI), allocation and hold priority. (Allocation and Retention Priority, referred to as ARP), and so on. Different bearers are usually applied to different data streams, such as voice, video, and data, which are usually assigned different QCIs and ARPs.

When the UE no longer needs to use a certain PDN connection, the UE may initiate a deactivation of the PDN connection request to the network, and the EPC core network releases the resources occupied by the PDN connection, including all EPS bearers in the PDN connection. The EPC core network can also initiate deactivation of the PDN connection when needed.

For the end user, when the user does not want to continue to use the data service, the user can manually close the data connection through the function menu of the terminal operation interface. This usually triggers the UE to automatically initiate a deactivation of the PDN connection request, and the network thus releases the resources of the PDN connection, including all bearers under the PDN connection.

However, the method used to close the data service is too rough and it is difficult to meet the user requirements after implementing LTE voice. After using the LTE voice service, the user hopes to turn off the normal data service, such as Internet access, while retaining the IMS voice service. However, the purpose of selectively turning off some data services cannot be achieved in the related art.

In view of the above problems existing in the related art, an effective solution has not yet been proposed.

The present invention will be described below in conjunction with specific embodiments:

Embodiment 1:

FIG. 7 is a first embodiment of the present invention. After attaching to the network, the UE sends a NAS request to the MME, and carries a PS data close indication.

Figure 7 has the following steps:

7A01~7A08, the UE requests to attach to the network, and the MME obtains the UE subscription data from the HSS. Create a default PDN connection for the UE. The following describes each step:

7A01, the UE sends an attach request (Attach Request) to the MME;

7A02, the MME sends a location update request (Update Location Request) to the HSS;

7A03, the HSS returns a location update response (Update Location Response) to the MME, and carries the UE subscription data.

In this step, the home network operator may set configuration information about the PS data off in the UE subscription data, such as:

- Whether the UE is allowed to enable the PS data off feature;

- Which APNs allow/disallow the PS data off feature to be enabled;

- Which services allow/disallow the PS data off feature to be enabled;

The operator may exempt certain data settings from PS data off according to the operation policy: IMS voice service, IMS video session service, IMS short message service, and the like;

7A04: The MME selects the SGW/PGW according to the APN information carried by the UE in the Attach request, or the default APN information in the UE subscription data received by the MME from the HSS, and sends a session creation request to the SGW/PGW (Create Session Request). );

7A05, the PGW sends an IP bearer setup request (IP-CAN Session Establishment Request) to the PCRF;

7A06, the PCRF returns an IP-CAN Session Establishment Response to the PGW, and carries the PCC policy;

7A07, the SGW/PGW returns a session creation response (Create Session Response) to the MME, and carries an EPS bearer list;

7A08, the MME returns an attach response to the UE, and carries an EPS bearer list;

7B01~7B07, after the UE determines that the PS data service needs to be closed, the UE sends a PS data close indication to the network in the NAS message, triggering the network to perform corresponding processing. include:

7B01, the UE sends a NAS message to the MME, and carries a PS data close indication;

In this step, the UE may use a TAU message or a Service Request message to carry a PS data close indication. Whether the UE is in the connected state (ECM-CONNECTED) or the idle state (ECM-IDLE), the UE may use the TAU message to transmit the PS data off indication. Correspondingly, if the UE is accessing from the UTRAN, the UE transmits a PS data close indication using the RAU message. If the UE is in an idle state, the UE may consider using a Service Request message to send a PS data close indication. Of course, the UE may also send a PS data close indication to the MME using other suitable NAS messages.

7B02, when the MME receives the NAS message of the UE, where the PS data close indication is carried, the MME forwards the PS data close indication to the SGW/PGW for processing, or additionally determines and processes the PDN connection;

In this step, if the MME does not participate in processing the PS data close indication according to the local policy, the MME forwards the PS data close indication to the SGW/PGW process. At this time, even if the MME obtains the configuration information of the PS data off from the UE subscription data acquired by the HSS, the MME will ignore the information.

Alternatively, before the MME forwards the PS data close indication to the SGW/PGW, the MME first performs a judgment process on the PDN connection, and the MME may determine the following manner:

The MME determines whether a PDN connection can be released: if the MME determines that all the bearers in a PDN connection can be released, the PDN connection can be released, and the MME can initiate a PDN connection release process for the PDN connection.

The MME determines whether a PDN connection is enabled for PS data off: if a PDN connection cannot be released, the MME determines whether to mark the PDN connection as PS data off. The MME may determine according to one or a combination of the following information: a local network policy, a PS data off configuration information (in the subscription data), an APN (used by the PDN connection), and the like. If the MME determines that PS data off is enabled for a certain PDN connection, the MME marks the PS data close indication in the PDN connection context.

The MME determines whether the PS bearer is enabled under a certain PDN connection. When it is determined that a PDN connection is enabled, the MME may further determine the PDN connection. Whether the EPS bearer enables PS data to be turned off. The MME may determine according to one or a combination of the following information: a local network policy, a PS data off configuration information (in the subscription data), an APN (used by the PDN connection), a QCI, an ARP, and the like. If the MME determines that a certain EPS bearer enables PS data to be closed, the MME marks the PS data close indication in the EPS bearer context.

7B03, the MME initiates a session modification request to the SGW/PGW, and carries a PS data close indication;

7B04, when the PGW receives the session modification request, where the PS data close indication is carried, the PGW determines whether the PDN connection/EPS bearer should be released, or whether the PS data is disabled;

In this step, the PGW can be judged by a combination of the following methods:

The PGW determines whether a bearer should be released: the PGW determines whether a bearer should be released according to one or a combination of the following information: local policy, APN, QCI, ARP, and the like.

The PGW determines whether the current PDN connection should be released. If all the bearers under the PDN connection should be released, the PDN connection should be released.

The PGW determines whether a bearer should enable PS data off: the PGW determines whether a bearer can enable the PS data off feature according to one or a combination of the following information: local policy, APN, QCI, ARP, etc.;

When the PGW determines that a bearer should enable PS data off, the PGW marks the bearer in one of the following ways:

The PGW instructs the EPS bearer to mark the PS data. According to the PS data close indication, the UE blocks uplink data transmission on the bearer, and the PGW blocks downlink data transmission on the bearer.

The PGW sets a special bearer filter template (TFT) for the EPS bearer. The uplink data of the UE cannot be matched to the EPS bearer through the setting of the special TFT, so as to prevent the UE from starting on the bearer. Uplink data transmission. Through the setting of the TFT, the downlink data of the PGW cannot be matched to the EPS bearer, so as to prevent the PGW from initiating downlink data transmission on the bearer.

If the PGW considers that it is necessary for the PCRF to determine whether a certain bearer enables PS data to be closed, the PGW sends an IP session modification request to the PCRF, carrying a PS data close indication;

7B05, the PGW sends an IP session modification request to the PCRF, and carries a PS data close indication;

7B06, the PCRF determines whether to allow the PS data to be disabled for the IP bearer;

After the PCRF receives the IP session modification request sent by the PGW, the PCRF determines whether the PS data off feature is enabled for the specified IP bearer as follows:

The PCRF determines whether the designated IP bearer is enabled to disable PS data according to the local policy or the subscription data obtained from the SPR; or

The PCRF performs an interaction with an Application Function (AF), and determines whether the designated IP bearer is enabled to disable PS data according to the interaction result.

When the PCRF determines that an IP bearer can be enabled to disable PS data, the PCRF marks the bearer as follows:

The PCRF indicates that the IP bearer flag PS data is closed; or,

The PCRF sets a special bearer filter template (Traffic Filter Template, TFT for short) to prevent the UE from initiating uplink data transmission on the bearer, and prevents the PGW from initiating downlink data transmission on the bearer. .

7B07, the PCRF returns an IP session modification response to the PGW;

In this step, the PCRF carries the PS data shutdown indication or carries a special TFT template in the IP bearer information.

7B08, the PGW pairs the PDN connection and the EPS bearer, and marks the PS data off indication;

According to the processing of the PGW in the aforementioned step 7B04, and the return information of the PCRF in the step 7B07, the PGW marks the PDN connection and the EPS bearer:

The PGW sets a PS data close indication in the PDN connection context;

The PGW instructs the EPS bearer to mark the PS data. Or, setting a special TFT template for the EPS bearer to achieve the purpose of prohibiting uplink and downlink data transmission;

For some special bearers, depending on the operator's policy or the indication of the subscription data, the PS data may not be enabled to be disabled. The PGW does not mark the PS shutdown indication for the bearer and does not set a special TFT template.

7B09, the PGW sends a session modification response message to the MME, and carries an EPS bearer list.

7B10, the MME marks the PDN connection and the EPS bearer according to the session modification response message returned by the PGW;

The MME marks the PDN connection according to the information returned by the PGW, that is, marks the PS data close indication in the PDN connection context.

The MME stores the EPS bearer context on the MME according to the EPS bearer list returned by the PGW. According to the processing in the foregoing steps, the EPS bearer in the EPS list may not be marked, may be marked with a PS data off indication, and may be set with a special TFT template.

7B11, the MME returns a NAS response message to the UE, and carries an EPS bearer list.

After receiving the EPS bearer list, the UE updates the EPS bearer context maintained by the UE itself. If an EPS bearer is marked as PS data off, the UE should prevent the uplink data transmission from being initiated on the EPS bearer. If an EPS bearer is configured with a special TFT template, the UE cannot match the uplink data to the bearer according to the TFT template, so that the UE can prevent the uplink data transmission from being initiated on the bearer.

It should be noted that, in the embodiment shown in FIG. 7, the MME and the PGW may perform the relevant judgment of whether to enable the PS data to be closed. According to the operator local policy, the judgments may be superimposed and combined with each other, and the final judgment result is judged by multiple parties. The result is superimposed, such as:

The MME does not perform the judgment, and only the PGW performs the judgment;

The MME and the PGW perform the judgment, and the MME determines the result of the PGW as the final judgment;

The MME does not perform the determination, the PGW performs the determination, and the PGW may request the PCRF to assist the determination.
