Problems solved by technology

[0006] When the data of all UEs are aggregated to the integrated gateway for processing, it is easy to cause a data flow bottleneck; and the integrated gateway lacks mechanisms such as load balancing and disaster recovery backup. If a single point of failure occurs in the integrated gateway, it will have an impact on the business very big

Embodiment 1

[0027] Embodiment 1 of the present invention provides a data transmission method, which is applied to a system including a gateway device, a UE, and different PDN networks, so as to image 3 It is a schematic diagram of the application scenario of the present invention, the gateway device may be a GGSN (or PGW in practical applications), and the PDN network includes but is not limited to an operator network (used to process operator traffic corresponding to the operator's own business) , HTTP (Hyper Text Transfer Protocol, hypertext transfer protocol) data network (for processing HTTP traffic), the Internet (for processing traffic corresponding to Internet services), etc.

[0028] Based on the above application scenarios, such as Figure 4 As shown, the data transmission method includes the following steps:

[0029] Step 401, the gateway device receives data from the UE. by image 3 For example, in the process of UE sending data, the data can be sent to GGSN through access ...

Embodiment 2

[0064] The following combination Figure 6 The shown application scenarios further illustrate the embodiments of the present invention. In the scenario where the UE accesses the cellular network core network GGSN or PGW gateway through WLAN (Wireless Local Area Networks, wireless local area network), in order to prevent all traffic from being sent to the core network GGSN or PGW, the WLAN access gateway can be configured with an IP address and / or port number filtering list, only perform GTP or PMIP encapsulation on the traffic that needs to go to the GGSN or PGW, and directly perform traffic offloading through the Internet for the traffic that does not need to go to the GGSN or PGW.

[0065] It should be noted that the above IP address and / or port number filtering list can be implemented in the following ways: 1) direct configuration; 2) configure the URL policy, then detect the DNS return message, and match the URL and IP address .

Embodiment 3

[0067] Based on the same inventive concept as the above method, the embodiment of the present invention also provides a data transmission device, such as Figure 7 As shown, the equipment includes:

[0068] A receiving module 11, configured to receive data from the user equipment;

[0069] The acquisition module 12 is configured to query a pre-maintained address filtering list through the destination address of the data to obtain the traffic type of the data, and the address filtering list is used to record the correspondence between addresses and traffic types;

[0070] The sending module 13 is configured to determine a target data packet network PDN network according to the traffic type of the data, and send the data to the target PDN network.

[0071] The device also includes: a maintenance module 14, configured to record the correspondence between addresses and traffic types in the address filtering list according to the configuration of the correspondence between address...

Abstract

The invention discloses a method and a device of data transmission. The method comprises that data from a user device are received through a gateway device; an address filtering list which is maintained in advance is inquired by the gateway device according to a destination address of the data, a flow type of the data is obtained, and the address filtering list is used for recording the corresponding relation between the address and the flow type; and a target public data network (PDN) is confirmed by the gateway device according to the flow type of the data, and corresponding process is conducted on the data or the data are sent to the target PDN. According to the method and the device of the data transmission, split-flow treatment is conducted on the data by the gateway device, data processed by a comprehensive gateway are sent to the comprehensive gateway, and therefore the data processing pressure of the comprehensive gateway can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique [0002] When a UE (User Equipment, user equipment) in a mobile network uses a data service, it needs to provide a corresponding APN (Access Point Name, access point name) to establish a connection, and different APNs can provide different routes for the UE, thereby Perform different data operations. It should be noted that an operator usually has multiple APNs, and the Internet service and the operator's own service usually use different APNs, have different routes, and perform different data operations. [0003] Such as figure 1 As shown, it is a schematic diagram of UE accessing different PDN (Packet Data Network, data packet network) networks using different APNs (such as WAP and NET). For self-owned service access, UE needs to use WAP (Wireless Application Protocol, wireless application protocol...
