Description
Technical Field
The invention relates to the field of wireless communication, in particular to a multi-channel allocation method.
Background
In radio resource management for wireless and cellular networks, a multi-channel allocation scheme allocates bandwidths and communication channels to base stations, access points and terminal devices with the goal of maximizing bit/sec/hz/station level spectral efficiency, but still guaranteeing a certain level of service through frequency reuse, avoiding co-channel interference and adjacent channel interference in adjacent cells or networks sharing the bandwidth.
The existing multi-channel allocation scheme is that a given idle channel can be accessed by a supposed cognitive terminal generated under the condition of not considering adjacent channel interference through a fixed channel allocation or dynamic channel allocation mode, but in an actual network, the communication quality of the terminal is reduced after the channel is allocated to the terminal due to various reasons.

if the second comparison result is the QoS max <In the case of the second threshold value,
according to the judgment of the UE and the QoS max And allocating a channel for the UE according to the result of whether the corresponding network equipment is accessed to the same access equipment.
Further, if the first determination result is the UE and the QoS max Corresponding network equipment is not accessed into the same access equipment, and the QoS is distributed to the UE max The corresponding network devices are the same channel.
Further, if the first determination result is the UE and the QoS max And the corresponding network equipment is accessed to the same access equipment, and the channel with the highest priority in the idle channels is allocated to the UE.
Further, if the second comparison result is the QoS max >And when the second threshold value is reached, not reallocating the channels for the UE.
The invention has the beneficial effects that: passing QoS max Comparison with a predetermined threshold when QoS is satisfied max When the QoS value of the link is smaller than the first threshold value, namely the QoS value of the link is smaller than the expected threshold value, the UE is allocated with the channel with the highest priority in the idle channels, the QoS value of the link can be improved, and when the QoS value is smaller than the first threshold value, the QoS value of the link is max Greater than a first threshold and QoS max Less than the second threshold, and UE and QoS max When the network equipment corresponding to the value is not in the same access equipment, the same channel as the network equipment is allocated to the UE, and the UE and the QoS are max When the network equipment with the corresponding value is in the same access equipment, the channel with the highest priority in the idle channels is distributed to the UE, whether the UE and the network equipment are in the same access equipment or not is judged, when the UE and the network equipment are in the same access equipment, the channel with the highest priority in the idle channels is distributed to the UE in order to prevent channel interference, and when the UE and the network equipment are not in the same access equipment, the channel with the highest priority in the idle channels is distributed to the UE max The corresponding network devices are the same channel. By using the multi-channel allocation method, the QoS value of the UE cannot be reduced after the channel is reallocated for the UE.
On the basis of the technical scheme, the invention can be further improved as follows.
Further, after the channel is reallocated to the UE, the quality parameters of the links between the UE and at least two network devices are continuously monitored, and the QoS value of each link is obtained;
judging whether the QoS value of each link is smaller than a first threshold value;
and if so, determining to reallocate the channel for the UE.
The invention has the beneficial effects that: and after the channel is reallocated, continuously monitoring the QoS value, and when the QoS values of all the links are smaller than the set threshold value, reallocating the channel for the UE to ensure that the QoS value is not reduced after the channel is reallocated by the UE.
