Abstract: An augmented reality communication method, apparatus, and system are provided. An auxiliary data channel is established between a terminal device and an AR media processing network element, and a target object is provided to the terminal device through the auxiliary data channel, to augment a media stream of AR communication between a first terminal device and a second terminal device, so as to integrate AR into voice and video calls. A third-party server may provide a material of the target object for the AR communication between the terminal devices, for example, a virtual object.

Abstract: The method provided in the embodiments of this application includes: obtaining, by a server, a first key (Ksm) shared with a gateway; receiving, by the server, an encrypted first random factor (Rand-M-Encry), a first data digest (Data-Hash), and encrypted first data (Data-Encry) that are sent by a terminal; decrypting, by the server, the Rand-M-Encry by using the Ksm, to obtain a second random factor (Rand-M′); performing, by the server, an operation on the Rand-M′ and Kpsa-xi by using a second preset algorithm, to generate a third key (K′sx); decrypting, by the server, the Data-Encry by using the K′sx, to obtain second data (Data′); performing, by the server, an operation on the K′sx and the Data′ based on a first preset algorithm to obtain a second data digest (Data-Hash′); and if the Data-Hash′ is the same as the Data-Hash, determining, by the server, that authentication of the terminal succeeds.

Abstract: Embodiments of the present invention relate to a method and an apparatus for processing random access in a wireless communication network, and a processing method of a user equipment and an apparatus. The method for processing random access in the communication network includes: the base station receives a first Zadoff-Chu sequence and a second Zadoff-Chu sequence that are sent by a user equipment, a du of the first Zadoff-Chu sequence is smaller than a du of the second Zadoff-Chu sequence; the base station estimates an error range for a round trip delay RTD of the user equipment according to the first Zadoff-Chu sequence, estimates, according to the second Zadoff-Chu sequence, the RTD within the error range for the RTD or a frequency offset of an uplink signal of the user equipment. The problem that the user equipment with a frequency offset accesses a network is solved.

Abstract: A video transmission method includes: A first media gateway receives an uplink media packet sent by a first terminal, where the uplink media packet carries information indicating that the first terminal supports an uplink-downlink resolution asymmetry capability and an uplink media stream of a first resolution of the first terminal. The first media gateway sends a first downlink media packet to the first terminal, where the first downlink media packet carries a downlink media stream of a second resolution of the first terminal, and the first resolution is different from the second resolution. The solution is applicable to the following example case: In a video call process, a terminal that supports different resolutions in a sending direction and a receiving direction can lower a resolution based on channel quality to deliver a video packet, and can raise the resolution when network resources are sufficient.
