It says, if being all occupied full with the carrier resource of frequency range with dominant frequency point, auxiliary frequency point and the carrier resource of dominant frequency alien frequencies section are also idle,
During new user's access, due to that can not suggest signaling, lead to small area jam, carrier resource utilization rate is low, the auxiliary frequency of cell alien frequencies section
Carrier wave is more, and cell carrier utilization rate is lower, in addition, the cell for being mixed networking, either dominant frequency A or dominant frequency F, by
In carrier wave attribute difference, R4 user preferentially occupies R4 carrier waves, and H user preferentially occupies H carrier waves, in this case, is likely to cause
There are abundant resources with the auxiliary frequency point of dominant frequency point alien frequencies section, the situation that user can not access influences user's perception；Its user accesses money
Source unreasonable distribution be easy to cause user and concentrates in some frequency range, another resource of frequency range is idle, and user's distribution is unbalanced existing
As causing carrier wave utilization rate not high, while be also easy to cause same frequency range inter-user interference.

The auxiliary frequency point of section access.
In the method for frequency point allocation proposed by the present invention, for being mixed networking cell, when user accesses, it is not intended that
Auxiliary frequency point whether with dominant frequency point using similar frequency bands, as long as cell carrier has resource, can normally establish signaling, but at this
Before, it needs to judge that the cell whether there is idling-resource namely judge the main carrier and secondary carrier of the cell respectively
With the presence or absence of idling-resource；If idling-resource is not present in only described main carrier, continuing to obtain the user currently can be into line frequency
The auxiliary frequency point of section access；If idling-resource is not present in the main carrier and the secondary carrier, it is determined that the cell occurs
Congestion, and the congestion information is informed into the user.
S102, selected from the auxiliary frequency point of acquisition an auxiliary frequency point as access auxiliary frequency point, and indicate the user according to
