The base station and the mobile terminal determine whether low frequency link synchronization is completed, and perform step 603 if low frequency link synchronization is completed. The mobile terminal determines, according to a data traffic requirement, whether to establish high frequency link synchronization, and performs step 607 if there is no need to establish high frequency link synchronization.
Step 604: Perform mutual authentication or exchange high-frequency frequency information using a low frequency channel.
If there is a need to establish high frequency link synchronization, step 604 is performed. The base station and the mobile terminal determine whether to perform mutual authentication or to confirm high-frequency frequency information of the two parties. If there is no need to establish high frequency link synchronization, step 607 is performed. If there is a need to establish high frequency link synchronization, the base station and the mobile terminal perform mutual authentication or confirm the high-frequency frequency information of the two parties, and then perform step 605.
Optionally, if the mobile terminal determines to establish high frequency link synchronization, the base station may pre-determine an access right of the mobile terminal. Likewise, the mobile terminal may also pre-determine an access right of the base station in order to avoid an unnecessary high frequency antenna connection.
Optionally, the mobile terminal and the base station may exchange the high-frequency frequency information of the two parties using the low frequency channel. In this way, complexity of high frequency beam alignment can be reduced, and high frequency beam alignment of a high frequency antenna can be further quickly implemented.
