Under the scenes of emergency, knapsack operation such as maritime affairs and the like, fishing boat transportation and the like in remote areas, the coverage area of the macro station cannot be extended to the extent, a reliable and stable wireless communication system is not provided for communication, the whole industry and the task are greatly influenced, and the micro base station is used as a powerful supplement for the scenes. However, since the backhaul network in this scenario usually adopts a satellite method, there are high requirements for the voice quality of UE access under the coverage of the micro base station and the cost brought by the satellite backhaul.
The invention aims to provide a voice optimization method and a voice optimization device of a micro base station aiming at a micro base station wireless coverage scene adopting satellite return, which are used for carrying out voice service optimization under the scene, have better applicability in the scenes of call service quality and cost, well solve the problem of voice quality under the scene of return bandwidth limitation and ensure the call quality of users.
Fig. 1 is a flowchart of a voice optimization method of a micro base station according to an embodiment of the present invention. Referring to fig. 1, a method for optimizing a speech of a micro base station according to an embodiment of the present invention specifically includes the following steps:
s11, obtaining the total bandwidth demand of each UE accessing the current micro base station, and comparing the total bandwidth demand with the back transmission network bandwidth threshold value of the micro base station.
In this embodiment, when the micro base station determines that the user equipment initiates the voice call request, the micro base station obtains a total bandwidth requirement of all UEs accessing the current micro base station, and determines whether the service quality of the voice service at this time is affected by the total bandwidth of the backhaul network by comparing the total bandwidth requirement with the backhaul network bandwidth threshold of the micro base station.
S12, if the total bandwidth requirement is greater than or equal to the backhaul network bandwidth threshold, sending a status indication message to the network side device, where the status indication message is used to request the network side device to reduce the voice service level of the UE accessing the current micro base station and currently performing the voice service.
When the total bandwidth requirement is greater than or equal to the backhaul network bandwidth threshold, the quality of service of the voice service is affected by the total bandwidth of the backhaul network. At this time, each UE accessing the current micro base station is traversed to obtain the UE currently performing the voice service. And then, sending a state indication message to network side equipment in a signaling mode, a data plane control flow mode and other modes so that the network side equipment reduces the voice service level of the UE which is accessed to the current micro base station and is currently carrying out voice service.
According to the voice optimization method of the micro base station provided by the embodiment of the invention, according to the total bandwidth requirement of each UE in the coverage range of the micro base station, if the total bandwidth requirement exceeds the size of the bandwidth threshold of the return network, speed reduction processing is carried out in a mode of reducing the voice service grade of each UE, so that the problems of packet loss, overlarge time delay and the like caused by exceeding the bandwidth threshold of the return network are avoided, the service quality of all UEs is further influenced, the voice call quality of a user is ensured to the greatest extent under the scene of limited return bandwidth, and the user experience is improved.
In the embodiment of the present invention, the total bandwidth requirement is obtained by the following method, which specifically includes: acquiring voice service grades of all UE accessed to the current micro base station, and respectively calculating the bandwidth occupation amount corresponding to each UE according to the voice service grades of all UE; and performing weighted calculation on the bandwidth occupation amount corresponding to each UE to obtain the total bandwidth requirement of each UE accessed to the current micro base station. For each access user, after receiving a voice call request message initiated by the UE, the voice service class of the UE can be extracted from the signaling interaction process with the UE.
In a specific embodiment, if the micro base station determines that the UE _1 initiates a voice call request, the micro base station extracts the voice service class of the UE _1 during the signaling interaction, performs network bandwidth calculation corresponding to the UE according to the voice service class, and simultaneously completes storage and recording, and records the occupied bandwidth Bw _1 required by the current service.
Then, every periodic time T, the micro base station performs weighted calculation on all the required bandwidths Bw _ i currently accessed to the base station UE to obtain a total Bw _ n. Specifically, the micro base station may perform the required bandwidth weighting calculation according to the currently recorded Bw _1 to Bw _ i.
The micro base station compares the value of Bw _ n with the value of the total bandwidth Bw of the currently available backhaul network, if Bw _ n is less than Bw, the total bandwidth of the backhaul network meets the requirement, which indicates that the service quality of the voice service at the moment is not affected by the total bandwidth of the backhaul network, and no processing is performed.
If Bw _ n > is Bw, considering that the voice quality is affected at this time, performing traversal of all UEs performing voice services, and informing the network side device through signaling, data plane control flow, and the like, so that the network side device reduces the voice service level of the UE currently performing voice services accessing the current micro base station, thereby reducing the bandwidth occupied by each UE. Specifically, the voice service grades corresponding to the UEs performing the voice service in the base station can be all reduced by one level.
Further, after the network side device reduces the voice service level of the UE currently performing the voice service accessing the current micro base station, obtaining a second total bandwidth requirement of each UE accessing the current micro base station, and comparing the second total bandwidth requirement with the backhaul network bandwidth threshold; and if the second total bandwidth requirement is greater than or equal to the backhaul network bandwidth threshold, sending a status indication message to network side equipment.
In practical application, after the network side device reduces the voice service level of the UE currently performing voice service accessing the current micro base station, the micro base station recalculates the second total bandwidth requirement of each UE accessing the current micro base station, compares the current Bw _ n 'with the Bw size again, and repeats the above steps until Bw _ n < Bw if Bw _ n' > is equal to Bw.
The scheme of the invention well solves the problem of voice quality under the scene of limited return bandwidth by periodically detecting whether the total bandwidth value required by the UE accessed by the micro base station is greater than the total bandwidth of the return network and carrying out corresponding optimization, so that the call quality of a user is ensured.
