Embodiment 1

[0038] This embodiment will be described from the perspective of a device using network topology information, and the device using network topology information may specifically be an SGSN.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides a direct tunnel control method, including:

[0040] 101. Obtain network topology information; the network topology information can reflect the composition and connection status of the entire network;

[0041] Among them, the network topology information can be obtained in any of the following ways:

[0042] (1) Receive the connection status information between the RNC and the GGSN sent by the Operations Support System (OSS, Operations Support System);

[0043] Certainly, can also receive before this the request of the Internet Protocol (IP, Internet Protocol) address of the GGSN that needs to detect that OSS system sends, then return the IP address list of the GGSN that needs to detect according to the req...

Embodiment 2

[0062] According to the implementation of a described method, an example will be given below to illustrate in detail.

[0063] In this embodiment, the OSS system is used as the network topology information collection unit and the network topology information distribution unit of the network topology information processing device, the RNC is used as the network topology information execution unit of the network topology information processing device, and the SGSN is used as the network topology information using device .

[0064] see figure 2 , the specific process can be as follows:

[0065] 201. The OSS system sends a request about the IP address of the GGSN to be detected to the SGSN.

[0066] It should be noted that step 201 is an optional step because the OSS system has stored the IP address of the GGSN in some scenarios.

[0067] 202. After receiving the request from the OSS system about the IP addresses of the GGSNs to be detected, the SGSN reports the IP address lis...

Embodiment 3

[0080] Same as the second implementation, in this embodiment, the OSS system is also used as the network topology information collection unit of the network topology information processing device, and the SGSN is used as the network topology information using device. The difference from the second embodiment is that in this embodiment , the GGSN is used as the network topology information execution unit of the network topology information processing device, and the DNS system is used as the network topology information distribution unit of the network topology information processing device.

[0081] The premise is that a domain name record with a direct tunnel identifier is configured in the DNS system. In addition to the direct tunnel identifier, the domain name also includes:

[0082] (1) Access Point Name (APN, Access Point Name), used to identify GGSN

[0083] (2) RNC identification (ID, Identity) or routing area code (Routing Area Code), used to identify RNC

[0084] The...

Abstract

The embodiment of the invention discloses a control method, a device and a communication system of a direct tunnel. The embodiment of the invention adopts obtained network topology information and then determines whether the direct tunnel is put into service according to the network topology information, for instance, when the connection condition between RN and GGSN is determined to be normal, the direct tunnel is put into service. As the scheme uses relative factors of establishing the direct tunnel, such as the dynamic network topology information as the condition for putting the direct tunnel into service, compared with the prior art, the method can more flexibly and effectively control whether the direct tunnel is put into service.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a direct tunnel control method, device and communication system. Background technique [0002] With the continuous development of the third-generation mobile communication technology (3G, 3rd-Generation) and the application of high-speed downlink packet access technology (HSPA, High Speed ​​Downlink Packet Access) and other technologies, the demand for user plane processing performance Increasingly, in order to meet these demands, it is necessary to increase radio network controller (RNC, Radio Network Controller), serving general packet radio service support node (SGSN, Serving GPRS Support Node, wherein GPRS is the abbreviation of General Packet Radio Service) and gateway GPRS support Node (GGSN, Gateway GPRSSupport Node) processing performance; and operators also need to reduce equipment investment and operating costs, and facilitate subsequent expansion. Therefore, the...
