Problems solved by technology

If the data transmission method in the prior art is adopted, before the UE sends the above-mentioned packet data to the network side each time, it is necessary to establish a control plane connection between the UE and the eNB, a control plane connection between the eNB and the core network, and a user plane connection. Bearer, as well as the user plane bearer process between UE and eNB, there are a lot of signaling interactions when establishing these connections / bearer processes, so a large signaling overhead will be generated, resulting in low system efficiency

Embodiment Construction

[0075] In order to better understand a data transmission method, user equipment, and network-side equipment provided by the embodiments of the present invention, the network architecture of the LTE system, the AKA security authentication and key negotiation process, and the connection / bearer establishment before data transmission are first described below. The process is described.

[0076] See Figure 1A , Figure 1A It is a schematic diagram of a network architecture of an LTE system. The LTE system network architecture mainly includes UE, evolved base station (EUTRAN Node B, eNB), mobility management entity (Mobility Management Entity, MME), serving gateway (Serving Gateway, S-GW), packet data gateway (Packet Data Network Gateway) , P-GW) and Home Subscriber Server (Home Subscriber Server, HSS), wherein, eNB is a network element in Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, EUTRAN), MME, S-GW, The P-GW and the HS...

Abstract

The present invention provides a data transmission method, user equipment, and network side equipment, wherein the method includes: the user equipment UE uses an encryption key and an integrity protection key to encrypt and integrity protect data packets, wherein the The encryption key and the integrity protection key are generated by the UE according to the first random number generated by the UE or the second random number received from the network side device, and the data packet includes the identity of the UE and user data; when the UE has not established a radio resource control RRC connection with the base station, the UE sends the encrypted and integrity-protected data packet to the network side device. The implementation of the present invention can realize safe transmission of data when no RRC connection is established between the UE and the base station, and reduce signaling overhead.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a data transmission method, user equipment and network side equipment. Background technique [0002] For the 3rd Generation mobile communication system (3rd Generation, 3G) and its Long Term Evolution (Long Term Evolution, LTE) system, in order to ensure the security of data transmission, before the user equipment (User Equipment, UE) transmits data to the network side, it must To carry out the security authentication and key agreement process between the UE and the network side, the Evolved Packet System (Evolved Packet System, EPS) authentication and key agreement (Authentication and Key Agreement, AKA) protocol is currently used in the LTE system to complete Security authentication and key agreement process between UE and network side. And before the security authentication and key negotiation process between the UE and the network side, the radio resource c...
