    Abstract: A first access network device determines a timing offset of a first carrier and a second carrier. The timing offset is an offset between timing of downlink communication of the first carrier and timing of uplink communication of the second carrier. The first carrier is a carrier using a first radio access technology (RAT), and the second carrier is an uplink frequency division duplex (FDD) carrier using the first RAT and a second RAT. The first access network device sends first indication information to a terminal. The first indication information indicates the timing offset, and the timing offset is used to determine the timing of the second carrier. Based on this scheme, the terminal can use a shared frequency band resource of LTE, thereby improving resource utilization.

    Abstract: In the field of communications technologies, a method and an apparatus for accessing an OTT application are disclosed. By using the accessing method, a user can access multiple OTT applications by using one piece of first user information, and therefore, the user does not need to record first user information separately for each OTT application, so as to reduce complexity of accessing multiple OTT applications. Three types of methods and apparatuses for pushing a message by a server are further provided. By using the message pushing methods, a server can push a message to a terminal that registers but does not enable a related OTT application, and the server can also push a message to a terminal that does not register a corresponding OTT application, so that a terminal does not need to receive a message only if a related OTT application is enabled.
