Abstract

The invention discloses a LTE terminal data routing method and system under a PGW pool network. The online information of the first LTE terminal is obtained through the first PGW, the first IP address is assigned to the first LTE terminal, and the first IP address is stored in the first LTE terminal. a hash table, and send the first gratuitous ARP message including the first IP address to the network side equipment, and the network side equipment receives the first gratuitous ARP message, and updates the network side ARP entry; The free ARP message is sent to the network-side device, so that the network-side device can learn the ARP entry of the terminal, and realizes the update and maintenance of the network-side ARP entry, so that the LTE terminal and the network-side device are connected by the original three-layer network It becomes a layer-2 network of the same IP network segment, so that each other can know each other's IP address and MAC address, and the network-side device can find out the corresponding relationship between the IP address and the MAC address, thereby encapsulating and forwarding the message, so as to Ensure smooth uplink and downlink routing of LTE terminal data.

Description

technical field

[0001] The present invention relates to the field of LTE wireless technology, in particular to a data routing method and system for LTE terminals under a PGW pool network. Background technique

[0002] With the maturity of the application of LTE wireless technology, all walks of life have begun to invest in the construction of LTE wireless networks. In the construction and application of the LTE network, it is found that many industry customers have a characteristic in the application of the LTE network that the IP address of the LTE terminal must be fixed and unique. When the data of the LTE terminal reaches the application server behind the LTE core network, the terminal IP address cannot be changed. Change, the application server needs to distinguish terminal services according to the LTE terminal IP address.

[0003] The LTE data plane structure is as follows: The LTE terminal IP address is assigned by the LTE core network element PGW, which can be under...
