Data packet forwarding method and device, data packet generating device and communication system

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...

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
