Long term evolution LTE network data closing method and device

Abstract

The embodiment of the invention provides a long term evolution LTE network data closing method and device and relates to the field of network data. The method comprises the steps of receiving a closing instruction for instructing closing of LTE network data service; deactivating public data networks PDNs between UE (User Equipment) and an LTE network, wherein the PDNs are used for transmitting network data packets between the UE and the LTE network; and forbidding the PDN to transmit data when only one activated PDN is reserved. According to the method and the device, the PDNs between the UE and the LTE network are deactivated, only one PDN is reserved, the PDN is forbidden to transmit the data, so the data communication between the UE and the LTE network is thoroughly disconnected.

Description

technical field [0001] The invention relates to the field of network data, in particular to a method and device for closing LTE network data. Background technique [0002] Realize long-term evolution (English: Long Term Evolution, LTE) network maintains the attachment function through the public data network (English: Public Data Network, PDN). Usually, a PDN needs to be reserved between the mobile phone and the LTE network to make the mobile phone online. [0003] Once the mobile phone is turned on, it establishes a default bearer with the LTE network. When the mobile phone has an Internet Protocol (English: Internet Protocol, IP) address, no matter whether the user uses the network data service, the mobile phone can already communicate with the LTE network. network to communicate. Usually, the LTE network will continuously send data packets to the mobile phone, such as detection packets, broadcast or multicast packets, and heartbeat packets. Since the data volume of these...

AI Technical Summary

Problems solved by technology

Usually, the LTE network will continuously send data packets to the mobile phone, such as detection packets, broadcast or multicast packets, and heartbeat packets. Since the data volume of these data packets is small, the proportion of the total traffic packets is not high, so users are very It is difficult to perceive traffic sneaking, but when users deliberately do not use network data services, or in some special scenarios, such as mobile phones in roaming state, the data volume of these data packets may be highlighted, and billing disputes may arise. When the mobile phone IP is obtained, or encounters malicious attacks and some network problems, high traffic charges may occur

[0004] At present, many mobile phones specially provide LTE data switch. Users can disable LTE by manually turning off the LTE data switch, but this switch only disables LTE, and the network connection between the mobile terminal and the LTE network still exists, so the mobile phone may still generate Phenomenon of traffic escaping
