Description
Technical Field
The invention relates to the technical field of communication, in particular to a carrier self-adaptive balanced seamless switching method and a mobile communication terminal.
Background
The multi-carrier trunking system requires that after a cell is established, a base station needs to continuously send signaling such as broadcast and the like on a main carrier, and after a traffic channel is established, service information is received and sent on a carrier corresponding to the traffic channel. Generally, after a cell is established, a channel machine used by a primary carrier is fixed and unchanged after the cell is established, and the allocation of a traffic channel generally follows a certain fixed allocation algorithm. The base station designed in this way inevitably causes the working time of the channel machine where the main carrier is located to be far longer than the working time of the channel machine where the service carrier is located. Meanwhile, the working time of the channel machines of each service carrier is greatly different. Since all the channel machines are consistent in physical design and structure, the theoretical operating time is the same, which results in the overall operating time of the base station being much shorter than the theoretical operating time.
Taking an N-carrier base station as an example, assuming that the theoretical operating time of a single channel machine is M, the theoretical operating time of the N-carrier base station is N × M. However, after the cell is established, the main carrier is always in a working state, and when the theoretical working time length M of the main carrier is exceeded, the channel machine where the main carrier is located fails, so that the actual working time length of the N-carrier base station is only M. Much less than its theoretical operating time. Even if the mode of switching the main carrier is adopted after the main carrier fails, the base station is degraded from an N-carrier base station to an (N-1) -carrier base station, and information loss can be caused in the main carrier switching. Similar imbalance also exists on the channel machines corresponding to the auxiliary carrier except the main carrier, and if the scheme of fixedly pairing the auxiliary carrier and the channel machines is adopted, imbalance of the working time length among the channel machines can also occur. Some channel allocation algorithms are given a certain complexity if they are used to average the carriers used for the traffic as much as possible.
In summary, how to provide a carrier adaptive balanced seamless handover method and a mobile communication terminal that can ensure the working efficiency of a multi-carrier base station and the continuity of service information in carrier handover is a problem that needs to be solved urgently by those skilled in the art.
