Embodiment Construction

[0041] The core idea of ​​the present invention is: when SGSN requests to update PDP context, it sends MS identification to GGSN, and GGSN uses the received MS identification to locate PDP context and update the information in the PDP context.

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0043] Figure 4 It is a flowchart of the SGSN updating PDP context of the present invention, such as Figure 4 Shown, the inventive method comprises the following steps:

[0044] Step 400: SGSN sends an update PDP context request message carrying MS identity to GGSN.

[0045] In this step, the update PDP context request message carries the user plane information to be updated, such as the IP address, TEID, QoS, etc. of the downlink tunnel, and the MS identifier such as IMSI.

[0046] Step 401: T...

Abstract

The invention discloses a method for updating the context of a packet data protocol, which is used, in a one-tunnel architecture, PDPs in one-tunnel mode. The method comprises the step that when requiring updating the context, an SGSN sends a mobile station (MS) identifier to a GGSN which consequently uses the received MS identifier to position the context of the PDP and to update the information in the context of the PDP. As a result, errors of location of the context of the PDP can be avoided, even if the context of the PDP is not available on the GGSN, thereby the SGSN can notice the uncommon condition of an upstream tunnel failure on a user plane between an access network and a core network, thereby avoiding the errors of data forwarding, accounting, etc. The method of the invention, compared with the prior method, requires no upgrading of RNC, thereby easily avoiding the technical problem due to the data upstream tunnel failure on a user plane between the access network and the core network, saving labor and money.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for updating a packet data protocol (PDP, Packet Data Protocol) context under a single tunnel / direct tunnel (OneTunnel / Direct Tunnel) framework. Background technique [0002] With the introduction of High Speed ​​Packet Access (HSPA, High Speed ​​Packet Access) and IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) into the 3rd Generation Partnership Project (3GPP) network, user plane data traffic will increase significantly. In order to improve the data transmission performance in the 3GPP network and reduce the operator's network investment, the 3GPP organization proposes a network architecture of One Tunnel / Direct Tunnel, which is hereinafter referred to as One Tunnel in this paper. [0003] In the One Tunnel network architecture, a user plane tunnel is directly established between the radio network controller (RNC, Radio Network Controller) in the access netwo...
