Embodiment 1

[0045] The MME sends a message to inform the gateway proxy SGW to suspend the relevant bearer. After receiving the message, the SGW will suspend the corresponding bearer. When the bearer resources are recovered, the MME notifies the SGW to resume use of the corresponding bearer resources and to send paging. see image 3 As shown, the concrete steps of embodiment one are as follows:

[0046] 1. A user equipment (UE, User Equipment) sends a measurement report to an evolved base station (eNodeB, Evolved Node Base).

[0047] 2. The eNodeB decides to initiate a handover procedure according to the measurement report. Then a handover request is sent to the source-side MME, and the message includes the content container (source to target container) from the source side to the target side, the identifier of the target access network, and the like.

[0048] 3. The MME initiates a standard PS-PS handover process and sends a forwarding handover request to the S-IWF. The message carries...

Embodiment 2

[0065] see Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the MME initiates the process of suspending the bearer after receiving the handover completion message sent by the S-IWF. Specific steps are as follows:

[0066] 1-13. Same as described in steps 1-13 in Example 1.

[0067] 14. The S-IWF notifies the MME that the user has switched to the target side.

[0068] 15. The MME sends a Handover Complete Response to the S-IWF.

[0069] 16. After learning that the user has switched to the target network, the MME sends a bearer suspension request to the gateway proxy SGW, and the message carries the bearer ID or user ID to be suspended. After receiving the request, the SGW suspends the corresponding bearer. After receiving the data packet, the SGW caches or discards the data packet, and for the user, the SGW will not send a paging process to page the user until the bearer is restored. until.

[0070] 17. The SGW sends a bearer suspension r...

Embodiment 3

[0072] see Figure 5 As shown, the difference between this embodiment and Embodiment 2 is that the gateway proxy in the system is PGW, and the bearer suspension request needs to be notified to the PGW, and the PGW will suspend the relevant bearer, and the PGW will cache or throw away. Specific steps are as follows:

[0073] 1-15. Same as described in steps 1-15 in Example 2.

[0074] 16. The MME sends a bearer suspension request to the SGW, and the message carries the ID of the bearer or user ID to be suspended.

[0075] 17. After receiving the bearer suspension request, the SGW sends the bearer suspension request to the corresponding PGW, and the message carries the bearer ID or user ID to be suspended. After receiving the request, the PGW suspends the bearer corresponding to the bearer ID or all the bearers corresponding to the user ID, and notifies the SGW that the bearer suspension operation is completed, and the message carries a cause value, indicating that the bearer...

Abstract

The invention discloses a method for hanging and recovering load bearing, and a proxy gateway. The method for hanging the load bearing comprises the following steps: the proxy gateway receives a load bearing hanging request sent by a mobile management entity (MME) when user equipment (UE) is switched from an EUTRAN to a GERAN; and the proxy gateway hangs the load bearing to be hung according to the request. The invention further discloses an implementation method for recovering the load bearing, and the method comprises the following steps: the proxy gateway receives a load bearing recovering request sent by the MME during the process that the UE is switched from the GERAN to the EUTRAN, the renewal process of a tracking area, or a service request process; and the proxy gateway recovers the load bearing to be recovered according to the request.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for bearer suspension and recovery. Background technique [0002] Such as figure 1 As shown, the core network of the wireless evolved network mainly includes three logical functional entities: a mobility management entity (MME, Mobility Management Entity), a serving gateway (SGW, Serving Gateway), and a packet data gateway (PGW, Packet Data Network Gateway). It is responsible for functions such as mobility management and user authentication, which corresponds to the control plane part of the Serving GPRS Support Node (SGSN, Serving GPRS Support Node) inside the current Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System); SGW Responsible for the local gateway proxy and the gateway proxy within the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) system and legally intercept related inform...
