Problems solved by technology

So for MME, if too many HNBs are directly connected to MME, the number of SCTP couplings on MME will be very large, seriously consuming MME resources, and MME will be overwhelmed; at the same time, HNB may be powered off and restarted at any time , which will cause the SCTP coupling between HNB and MME to be continuously established or closed, which will also cause a great impact on MME and increase the processing load of MME

Embodiment 1

[0027] like figure 1 As shown, Embodiment 1 of the data packet forwarding method provided by the embodiment of the present invention includes:

[0028] Step 101, receiving a data packet from the message sending end, the data packet is transmitted through the pre-established first transmission protocol signaling channel with the message sending end, including the message receiving end identifier and the application layer message;

[0029] Wherein, the data packet can be an SCTP data packet, an IP data packet, a TCP data packet, etc. When it is an SCTP data packet, the first transmission protocol signaling channel is the first SCTP coupling, and according to different message types of the SCTP data packet, it needs Sent via the stream corresponding to the message type on the first SCTP connection. The application layer message is different according to the interface between the message sending end and the message receiving end. For example, it can be the S1 application layer (S...

Abstract

The embodiment of the invention discloses a data packet forwarding method, a device thereof, a data packet generating device and a communication system. The data packet forwarding method comprises the following steps: a first data packet sent from a message sending terminal through a first transmission protocol signaling channel is received, and the first data packet contains a message receiving terminal mark and application layer messages; a second transmission protocol signaling channel corresponding to the message receiving terminal mark is selected; and a second data packet is sent to the message receiving terminal through the second transmission protocol signaling channel, and the second data packet contains the application layer messages. The invention also provides the data packet generating device, the data packet forwarding device and the communication system. By adopting the technical proposal provided by the embodiment of the invention, the processing load of network nodes which communicate with HNB can be reduced, and the network nodes can not be impacted by the restart and the power cut of the HNB.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data packet forwarding method and device, a data packet generating device and a communication system. Background technique [0002] With the vigorous development of Internet (Internet) services and the wide application of broadband access networks and wireless networks, high-speed and convenient access to the network is the goal pursued by people. In order to make better use of existing network resources and protect the cost of network equipment operators, the Third Generation Partnership Project (3GPP) has started research work on home base stations (HNB: Home Node B). HNB refers to a miniaturized small base station for home or office use. It may be completely private, or it may be open to the public with different priorities and permissions. Its ownership belongs to private individuals, not to the government or operation. business. Using HNB to implement wireless acc...
