Problems solved by technology

When the UE deletes its bearer resources related to the EPS but still performs service offloading, it is necessary to consider the deletion of the session shared by the two, such as the S9* session and the S9 session, but in the prior art, there is no related solution

Embodiment 1

[0059] image 3 It is a schematic flow diagram of Embodiment 1 of the control method for realizing a shared session in the present invention. In a non-roaming access scenario, when the UE executes the process of deleting the last PDN connection to access the 3GPP core network, the PCRF determines that the UE has service offload capability , the specific implementation method of not deleting the shared session, such as image 3 As shown, the method includes the following steps:

[0060] In step 301, the UE executes a 3GPP-based access authentication process, and a network element of the fixed network assigns a local IP address to the UE.

[0061] Step 302, in the UE attach procedure, the network element of the fixed network sends a message to the BPCF to trigger the BPCF to establish an S9* session.

[0062] Step 303, after the BPCF is triggered by the network element of the fixed network, it sends an S9* session establishment request message to the PCRF to establish the S9* ...

Embodiment 2

[0073] Figure 4 It is a schematic flow diagram of Embodiment 2 of the control method for realizing a shared session in the present invention. In a roaming access scenario, when the UE executes the process of deleting the last PDN connection to access the 3GPP core network, the PCRF determines that the UE has the service offload capability When the shared session is not deleted, the specific implementation method of the shared session is not deleted; for the roaming access scenario, the application function (AF, Application Function) is located in the roaming area, and the deletion of the S9* session between BPCF and vPCRF needs to be considered. If you need to refer to the home policy decision, will also establish an S9 session, and also need to consider the deletion of the S9 session between vPCRF and hPCRF; for example Figure 4 As shown, the method includes the following steps:

[0074] In step 401, the UE executes a 3GPP-based access authentication process, and a network...

Embodiment 3

[0087] Figure 5 It is a schematic flow diagram of Embodiment 3 of the control method for realizing a shared session in the present invention, and it is a schematic diagram of the process in which the UE deletes the last PDN connection process for accessing the 3GPP core network in the home access scenario, and the PCRF determines that the UE has the service offload capability When the shared session is not deleted, the specific implementation method of the shared session is not deleted; for the home access scenario, where the AF is located at the home, it is necessary to consider the deletion of the S9* session between BPCF and vPCRF, and the deletion of the S9 session between vPCRF and hPCRF; Figure 5 As shown, the method includes the following steps:

[0088] In step 501, the UE executes a 3GPP-based access authentication process, and a network element of the fixed network allocates a local IP address for the UE.

[0089] Step 502, in the UE attach process, the network el...

Abstract

The invention discloses a method for controlling a shared session. The method includes that UE (user equipment) supports direct distribution via a non-3GPP (3rd generation partnership project) network and simultaneously accesses a 3GPP core network; and a strategy control functional entity determines whether the shared session needs to be deleted or not according to whether the UE has service distribution ability or not when the last PDN (public data network) accessing the 3GPP core network is deleted. The invention further provides the strategy control functional entity. According to the technical scheme, the method and the strategy control functional entity have the advantage that a gap of a scheme for processing a shared session for UE via WLAN (wireless local area network) in a scene that direct service distribution is supported and a core network is accessed in the prior art is filled.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for controlling a shared session. Background technique [0002] The Evolved Packet System (EPS, Evolved Packet System) of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) consists of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), mobile management Unit (MME, Mobility Management Entity), Serving Gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW, Packet Data Network Gateway) and Home Subscriber Server (HSS, Home Subscriber Server). [0003] figure 1 It is a schematic structural diagram of a system for interworking between a 3GPP network and a non-3GPP network in the prior art, such as figure 1 As shown, EPS supports interworking with non-3GPP systems through S2a / S2b / S2c interfaces, where the P-GW is the anchor point between the 3G...
