  • Patent number: 9232404
    Abstract: Embodiments of the present invention disclose a method, an apparatus, and a system for data transmission. The method for data transmission includes: determining that data to be transmitted is control plane signaling related to a user equipment that camps on a relay node; and transmitting the data through a first user data bearer established between the relay node and a donor base station, where the first user data bearer provides integrity protection for the data. According to the embodiments of the present invention, when the control plane signaling related to the user equipment that camps on the relay node is transmitted between the relay node and the donor base station, integrity protection is provided for the control plane signaling, and therefore attacks such as the denial of a service attack are prevented.

  • Patent number: 8908863
    Abstract: A method, network element, and mobile station (MS) are disclosed. The method includes: obtaining information that a plug-in card of the MS does not support a first encryption algorithm; deleting the first encryption algorithm from an encryption algorithm list permitted by a core network element according to the information that the plug-in card of the MS does not support the first encryption algorithm; sending the encryption algorithm list excluding the first encryption algorithm to an access network element, so that the access network element selects an encryption algorithm according to the encryption algorithm list excluding the first encryption algorithm and the MS capability information sent from the MS and sends the selected encryption algorithm to the MS. By using the method, network element, and MS, errors due to the fact that the plug-in card of the MS does not support an encryption algorithm may be avoided during the encryption process.
