Embodiment mono-
With reference to Fig. 3, show a kind of flow chart of steps of carrying out the method for speech business in enterprise network of the embodiment of the present invention one.The method step that carries out speech business in enterprise network of the present embodiment is as follows:
Step S302: integrated base station receives the voice service request that in enterprise network, calling terminal sends.
Wherein, Intranet comprises integrated base station and enhanced router, and integrated base station comprises base station functions module and core net functional module.Enhanced router connects respectively public network equipment and integrated base station.Enterprise network takies the frequency spectrum resource that public network is set frequency range.
The LTE enterprise network is before deployment, and enterprise network operator needs and public network operator reaches an agreement.Public network operator hires out certain frequency spectrum resource, and frequency spectrum resource is only effective in the building scope, for dispose the LTE system in building, uses.User in enterprise network uses when carrying device, and the user's is common apparatus from carrying device, only can support the public network frequency spectrum resource.After enterprise network has been leased certain frequency spectrum resource of public network, when enterprise network takies the frequency spectrum resource of public network setting frequency range, what the user in enterprise network used just can realize automatically switching between enterprise network and public network from carrying device.
Step S304: integrated base station is according to the terminal called of priority and the voice service request of calling terminal, for the EPS carrying that meets the QoS demand parameter is set up in the corresponding speech business of voice service request.
In enterprises, the terminal that each employee has has a terminal iidentification, IMSI(International Mobile Subscriber Identification Number international mobile subscriber identity for example) or telephone number, each sign has corresponding priority, after priority is determined, each priority level is to there being corresponding QoS demand parameter accordingly.Above-mentioned these information can or be kept in integrated base station with other forms with the form of tables of data.During voice service request that terminal in integrated base station receives enterprise network sends, integrated base station obtains the terminal iidentification of calling terminal from request, and the sign of terminal called; And then obtain the priority corresponding to terminal iidentification of calling terminal from integrated base station this locality, and QoS demand parameter corresponding to this priority, for the EPS carrying that meets the QoS demand parameter is set up in the speech business between calling terminal and terminal called.
The method of the QoS demand parameter that a kind of priority of setting each terminal and each priority are corresponding is as follows:
At first, carry out the priority of setting terminal according to self the qualification situation of the user by terminal, as: the priority of the terminal that boss uses is the highest, is secondly the vice president, successively each terminal PRI of enterprises sorted, priority corresponding to the terminal that common employee uses is minimum.The feasible pattern of another kind of setting terminal priority is: the priority of carrying out setting terminal according to the demand of the user by terminal, as: a certain user mainly is responsible for the work of enterprises voice broadcast service, according to the priority of this terminal of need of work, is set to the highest so.It should be noted that, foregoing just two kinds of feasible methods of the priority of setting terminal, the setting scheme of the concrete priority to terminal can be adjusted voluntarily according to the demand of each enterprise.Secondly, the terminal correspondence that priority is high arranges preferably QoS demand parameter, as larger bandwidth, lower time delay, less packet loss etc., with the speech service quality that guarantees that this terminal is asked.
The basic granularity that QoS controls is the EPS carrying, and integrated base station is set up corresponding EPS carrying according to the priority of terminal for each terminal; All data flow in identical EPS carrying will obtain identical QoS and ensure, carry the desired QoS of corresponding qos parameter demand and ensure.
When a plurality of terminals are initiated voice service request to integrated base station simultaneously, integrated base station, at first by the terminal iidentification of terminal, obtains priority and the corresponding QoS demand parameter of the terminal that each terminal iidentification is corresponding.Corresponding EPS carrying is set up in the speech business that integrated base station is its initiation according to the priority level of each terminal.The terminal use who has guaranteed high priority can enjoy high-quality service, as: the request that this terminal of priority treatment is initiated, and can guarantee the loss without packet when this terminal is carried out speech business, time delay is little, non-jitter etc. guarantees the fluency of speech business.
What by the present embodiment, provide carries out the method for speech business in enterprise network, wherein, be provided with integrated base station and enhanced router in enterprise network, enhanced router connects respectively public network equipment and integrated base station, enterprise network takies the frequency spectrum resource that public network is set frequency range, for the terminal in enterprise network provides radio communication service.The scheme of carrying out speech business that adopts the present embodiment to provide, when the calling terminal in enterprise network is initiated voice request to integrated base station, the EPS carrying that meets the qos parameter demand is set up in the integrated base station speech business that corresponding qos parameter demand is the calling terminal request according to priority, terminal called and the priority of calling terminal.The high priority terminal is high to the QoS demand, and correspondingly, integrated base station can provide for the speech business that the high priority terminal is asked the EPS carrying of high-quality.The speech business of asking for the low priority terminal, integrated base station can be set up relatively low-quality EPS carrying for it.The scheme provided by the present embodiment, solved in existing enterprise network when adopting cable network and WiFi network, when having a plurality of users to initiate real-time voice class service request simultaneously, voice quality can be greatly affected, cause the speech service quality of responsible consumer can not guaranteed problem, guarantee the user's of high priority speech service quality in the enterprise network, to the user, brought better service experience.
Embodiment bis-
With reference to Fig. 4, show a kind of flow chart of steps of carrying out the method for speech business in enterprise network of the embodiment of the present invention two.
The concrete steps of method of carrying out speech business in the enterprise network of the present embodiment are as follows:
Step S402: integrated base station receives the voice service request that the calling terminal in enterprise network sends.
A plurality of terminals are arranged in enterprise network, and when a plurality of terminals are initiated voice request simultaneously, different EPS carryings, the voice quality of the speech business that the terminal of assurance high priority is initiated are set up in the speech business that integrated base station will be initiated each terminal so.
Step S404: integrated base station obtains priority and the QoS demand parameter corresponding to priority of calling terminal from this locality.
In enterprises, the terminal that each employee has has a terminal iidentification, for example IMSI or telephone number, and each sign has corresponding priority, after priority is determined, QoS demand parameter corresponding to each priority level accordingly.Above-mentioned these information can or be kept in integrated base station with other forms with the form of tables of data.During voice service request that terminal in integrated base station receives enterprise network sends, integrated base station obtains the terminal iidentification of calling terminal from request, calling terminal identification and the terminal iidentification of local storage are mated, and the terminal iidentification of local storage is to there being QoS demand parameter corresponding to priority and priority; Thereby obtain the priority of calling terminal identification, and QoS demand parameter corresponding to this priority.Also, integrated base station obtains priority and the QoS demand parameter corresponding to this priority of calling terminal from this locality.
Preferably, integrated base station can also obtain priority and the QoS demand parameter corresponding to priority of calling terminal from voice service request.Carrying priority and the QoS demand parameter corresponding to priority of calling terminal in the voice service request that calling terminal is initiated, after integrated base station obtains voice service request, directly from voice service request, obtain priority and the QoS demand parameter corresponding to priority of calling terminal.
The mode of another kind of feasibility is: integrated base station can also obtain the priority of calling terminal from voice service request, and obtains QoS demand parameter corresponding to priority from this locality.Concrete steps are: integrated base station receives the voice service request that calling terminal sends, the priority of carrying calling terminal in request; Integrated base station obtains the priority of terminal from request; And find this priority in the priority list of each terminal from the enterprise network of this locality storage, wherein, also comprise QoS demand parameter corresponding to each priority in the priority list of local storage, thereby obtain QoS demand parameter corresponding to this priority.
Step S406: when voice service request is normal voice calls, integrated base station obtains the sign of terminal called from speech business.
In the present embodiment, take voice service request as normal voice calls is example, but be not limited to this, voice service request can be also the voice broadcast service request.When voice service request is the voice broadcast service request, the other-end in the selection enterprise network is as terminal called.
It should be noted that, step S406 carries out after being not limited to step S404, can carry out with step S404 simultaneously, also can before step S404, carry out.
Step 408: integrated base station, according to the priority of calling terminal, is set up the EPS carrying that meets the QoS demand parameter between calling terminal and integrated base station and integrated base station and terminal called.
Each priority is to corresponding QoS demand parameter should be arranged, and integrated base station receives the voice service request that calling terminal is initiated, and obtains the terminal iidentification of calling terminal from voice service request, and the terminal iidentification of terminal called; Store the information of QoS demand parameter corresponding to priority that in enterprise network, each terminal iidentification is corresponding and priority in this locality.Integrated base station is determined priority corresponding to terminal be complementary with calling terminal priority, and obtains QoS demand parameter corresponding to this priority; Set up the EPS carrying that meets the QoS demand parameter between calling terminal and integrated base station and integrated base station and terminal called, wherein, the QoS demand parameter is corresponding with calling terminal priority.
The EPS carrying is the basic granularity that QoS controls, and all data flow on same bearer will obtain identical QoS and ensure.Integrated base station, according to the priority of each terminal, provides corresponding scheduling strategy, buffering queue management and link layer configuration according to priority, for the voice service request that each terminal sends is set up corresponding carrying; That is, the terminal that priority is high, will be put under the high priority queue, and the voice request scheduling that this terminal is corresponding is joined the team and sends, and guarantees the user's that priority is high speech service quality.The voice service request that low terminal is initiated for priority, may cause because bandwidth does not allow data-bag lost, and even integrated base station also may not can connect for this terminal provides speech business.
Scheduling strategy is a very important part in QoS.Adopt the priority queueing scheduling strategy in the present embodiment, be about to network traffics and be defined as four queues, the priority of these queues is respectively: high, in, common and low.Integrated base station carrys out processing queue in strict accordance with the priority of terminal.If in the high priority queue, packet is arranged, this queue will be processed until it is for empty so, once the high priority queue is empty, integrated base station, by diversion treatments middle rank priority queue, is processed a packet so, then integrated base station can check again whether the high priority queue is empty, if so, it can continue to process intermediate priority queueing, the like, then being regular grade, is then rudimentary.Priority queueing can be controlled network traffics, sets in the present embodiment accordingly the high terminal of priority and enjoys high priority.
It should be noted that, the QoS demand parameter comprises at least one in amount of bandwidth, time delay size and packet loss size; And/or, there is identical scheduling strategy, buffering queue management and link layer configuration in same EPS carrying.That is to say, the QoS demand parameter comprises at least one in amount of bandwidth, time delay size and packet loss size, can be any independent parameter in bandwidth, time delay and packet loss, can be also any two parameters or comprises this three parameters simultaneously.There is identical scheduling strategy, buffering queue management and link layer configuration in same EPS carrying.For example, when the QoS demand parameter is arranged, the size of bandwidth can only be set, meet so in the EPS carrying of same band there is identical scheduling strategy, buffering queue management and link layer configuration; The size in broadband and the size of time delay also can be set, and the EPS carrying that meets so accordingly same wideband, same delay has identical scheduling strategy, buffering queue management and link layer configuration.
Preferably, while only having a terminal to initiate voice request to integrated base station in enterprise network, integrated base station obtains the priority of terminal, and gives tacit consent to QoS demand parameter corresponding to this priority for optimum.For example: in enterprise network, a certain employee initiates voice service request by its terminal, now, the terminal that does not have other staff to pass through oneself in enterprise network is initiated voice service request, after integrated base station will receive the voice service request of this terminal so, at first by all signs in the enterprise network of the sign by terminal and storage, mated, the priority that obtains this terminal is rudimentary; Although this priority is rudimentary, so because do not have the terminal that other priority is high to initiate voice request in enterprise network, integrated base station will be given tacit consent to the QoS demand parameter that provides optimum, for optimum EPS carrying is set up in the speech business that this terminal is initiated, can guarantee that the transmission bandwidth that this speech business obtains is enough large, propagation delay time is short, the data packet loss is low and non-jitter etc.
Below with a terminal in enterprise network, to integrated base station, initiate the voice broadcast service request, it is example that integrated base station is set up Voice Broadcast Service for this terminal, and the method for carrying out speech business in enterprise in the present embodiment is specifically described.Idiographic flow is as shown in Figure 5: terminal A is the demand that UE-A has Voice Broadcast Service, to integrated base station, is that FAT Cell initiates voice service request, as this voice service request is carried on to adhere in request, to FAT Cell, sends; FAT Cell sets up corresponding EPS carrying according to the priority level of UE-A; FAT Cell is using the other-end in enterprise network as terminal called, such as: terminal B is that UE-B, C are that UE-C, D are a plurality of terminals such as UE-D; FAT Cell sends linking request to a plurality of terminals such as terminal UE-B, UE-C, UE-D, sets up the speech business of UE-A and other relevant UE, is UE-A and sets up voice broadcast service.If, in this instantiation, in enterprise network, there are a plurality of UE to initiate a plurality of voice service request to FAT Cell simultaneously, FAT Cell is after receiving voice service request so, can be according to the priority level of each UE and the corresponding QoS demand parameter EPS carrying special-purpose for each UE sets up, wherein, FAT Cell divides the EPS carrying according to the corresponding priority of UE and QoS demand parameter corresponding to each priority; Realize that the LTE voice broadcast service provides the service of corresponding quality of service guarantee and various differentiation.For example, if the priority of UE-A higher than UE-B, FATCell can be at first set up the speech business link for UE-A so, and when receiving the packet of UE-A transmission, the packet that priority treatment UE-A sends, can not abandon it, guarantees the speech business smoothness of UE-A.And UE-B only meets under the precondition of demand of UE-A at FAT Cell, just can process the voice request of UE-B, for it establishes the link, carry out the transmission of packet.
What by the present embodiment, provide carries out the method for speech business in enterprise network, when the calling terminal in enterprise network is initiated voice service request to integrated base station, the QoS demand parameter that integrated base station is corresponding according to priority, this priority of calling terminal and the information of terminal called are as the sign of terminal called, for the speech business of calling terminal request provides corresponding EPS carrying, the QoS demand parameter of the corresponding high-quality of the terminal of high priority, correspondingly, integrated base station can be set up for the speech business that the terminal of high priority is asked the EPS carrying of high-quality.The speech business that low terminal is asked for priority, integrated base station can be proposed the EPS carrying of relative mistake.While only having terminal to initiate voice request in enterprise network, integrated base station can provide the EPS carrying of this terminal optimum, for the speech business of this terminal provides optimal service.The scheme provided by the present embodiment, solved in existing enterprise network when adopting cable network and WiFi network, when having a plurality of users to initiate real-time voice class service request simultaneously, voice quality can be greatly affected, cause the speech service quality of responsible consumer can not guaranteed problem, guarantee the user's of high priority speech service quality in the enterprise network, to the user, brought better service experience.
