Embodiment 1

[0030] This embodiment provides a method for capturing packets, such as figure 1 shown, including:

[0031] S101. Receive a packet capture request, where the packet capture request carries a redirection path of the data packet. The packet capture request may be a request issued by a network management system or a processor, or a request issued by other functional entities. For example: when the MAC layer of the base station captures packets, a packet capture request can be issued through the local maintenance terminal of the base station.

[0032] S102. Back up the currently sent data packet to the storage device indicated by the redirection path. That is, according to the packet capture request, a link for packet capture is self-built, and the currently transmitted data stream is backed up to the storage device through this link. The storage device may be an external memory. For example: it can be a large-capacity floppy disk, hard disk, CD-ROM or flash disk.

Embodiment 2

[0037] In this embodiment, the packet capture method provided in Embodiment 1 is applied to a base station of an LTE system. The base station includes: a MAC layer and a baseband processing unit. There is a local maintenance terminal on the periphery of the base station, which can be used to issue a packet capture request and provide external storage such as a hard disk to store data packets. Normally, the MAC layer sends the data packet to the baseband processing unit after processing the data. But when there is a problem in the network, it is necessary to locate the network fault by capturing the data packets transmitted between the MAC layer and the baseband processing unit. Such as figure 2 As shown, when network problems arise, including:

[0038] S201, the local maintenance terminal sends a packet capture request to the MAC layer, and starts a packet capture process. The packet capture request instructs the MAC layer to back up the captured data packets to a local h...

Embodiment 3

[0047] Corresponding to the foregoing method embodiments, this embodiment provides a packet capture device and a communication system.

[0048] Such as image 3As shown, the communication system provided by this embodiment includes: a source device 1 (for example: the local maintenance terminal in Embodiment 2), a packet capture device 3 (for example: the MAC layer in Embodiment 2) and a storage device 5 (for example : the hard disk in the second embodiment). in:

[0049] The source device 1 is used to create a packet capture request, and the packet capture request carries a redirection path of the data packet; and sends the created packet capture request to the packet capture device 3;

[0050] The packet capture device 3 is configured to receive the packet capture request sent by the source device, and back up the currently sent data packet to the storage device indicated by the redirection path;

[0051] The storage device 5 is used for storing the data packets sent by t...

Abstract

The embodiment of the invention provides a packet capturing method and equipment, relates to the communication technical field and aims to solve the problem that packet capturing during demultiplexing can not be provided through transmission equipment. The method comprises the following steps: receiving a packet capturing request which carries the redirect path of a data packet; and backing up a currently sent data packet and storing the back up in storage equipment shown by the redirect path. The system comprises source-end equipment, packet capturing equipment and the storage equipment, wherein the source-end equipment is used to establish and transmit a packet capturing request carrying the redirect path of a data packet to the packet capturing equipment; the packet capturing equipment is used to receive the packet capturing request transmitted by the source-end equipment and stores a copy of the currently transmitted data packet in the storage equipment shown by the redirect path; and the storage equipment is used to store the data packet transmitted by the packet capturing equipment. The method and the equipment provided by the embodiment of the invention can be widely used in communication systems including LTE, UMTS, and so on.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method, device and system for capturing packets. Background technique [0002] In UMTS (Universal Mobile Telecommunications System, universal mobile communication system), RNC (Radio Network Controller, radio network controller) is separated from NodeB (base station), and RNC completes the processing of MAC layer (Media Access Control, medium access control layer), The NodeB is deployed with a baseband processing unit, and the base station controller and the base station are connected by a network cable or E1. The data processed by the MAC layer is sent to the baseband processing unit. If you want to capture the data packets sent by the MAC layer to the baseband processing unit, you can install hardware such as Nethawk on the network port to capture packets. [0003] The current hardware packet capture method is to open a shunt on the transmission equipment that...
