Abstract
The method comprises: during a communication process, as the request side, the calling side or called sends a request message for changing the communication service level to the network side trough a terminal; according to the request message, the core network of the request side selects the communication parameters matching the request message, and generates the execution message for reconfiguring said communication parameters; according to the reconfigured parameter, the network side changes the service level of the current communication; ending.
Description
Technical field
The present invention relates to the method for change communication service levels in a kind of communication process, relate in particular to a kind of method that in communication process, communication service levels is changed based on user's request.Belong to communication technical field.
Background technology
Along with the develop rapidly of mobile communication network technology, people have proposed increasingly high requirement to the communication service technology, can choose at random the communication service of different tariff when hoping communication, promptly can select communication service levels.
At present, have two kinds of technology can satisfy people's this demand, a kind of being based on " class of subscriber " realized communication QOS; Another kind is based on the calling subscriber and adds to dial and connect into prefix and realize communication QOS.
Realization principle based on the technical scheme of " class of subscriber " is as shown in Figure 1, specifically carries out following steps:
Steps A. the mobile subscriber in the mobile communications networks such as GSM is classified, corresponding " class of subscriber " is set in the user data management system, the priority that each " class of subscriber " is corresponding certain through customer service system or business operation support system;
Step B. core net (or switching network) equipment obtains mobile subscriber's " class of subscriber " from the user data management system in the process of the user being carried out mobile management;
Step C. at mobile communications network when the mobile subscriber provides this user as caller or called communication service; Mobile subscriber's " class of subscriber " and the tenability of the used portable terminal of current this user analyzed in core net (or switching network) equipment complex, notifies the pairing communication service levels relevant information of this user (like channel type, code rate etc.) to wireless access network equipment then;
Step D. wireless access network equipment under the high load capacity situation, will distribute corresponding wireless network resource for it according to the principle of " priority is different, and the channel coding method of distribution is different " according to this user's communications grade of service relevant information.And for high level user, even under the situation of wireless access network resource anxiety, mobile communications network also will be preferably it high-rate coded wireless access business will be provided.
The defective that this technology exists is that the user is set to a certain " class of subscriber " afterwards, as caller or called the conversation time, and can only be according to communicating with this " class of subscriber " corresponding communication grade of service.The user is if want the Iterim Change communication service levels; Just must in the user data management system, revise " class of subscriber " through customer service system or business operation support system is provided with; Therefore; Be difficult in real time communication service levels to be set to each conversation, the user can not be in communication process this communication service levels of temporary changes.For example, the lower low end subscriber of communication service levels is when dialing important phone, and is higher to the service request of speech quality, and just hoping can the temporary changes communication service levels, to select higher communication service levels, even this phone is more expensive; In the time of the higher high-end user extended telephone conversation of communication service levels, maybe be not high to the service request of speech quality, the demand of Iterim Change communication service levels is just arranged, select lower communication service levels, make that telephone charges can be cheaper.The demand of this change communication service levels maybe initiation before communication is set up, also maybe be in communication process Iterim Change.And thisly realize that based on " class of subscriber " technology of communication QOS is difficult to call out one by one ground, dynamically satisfies this same user different demands for communication service levels under the different call scene.
It is as shown in Figure 2 to add the realization principle of dialing and connecting into the technical scheme of prefix based on the calling subscriber, when the user makes a call, can before the called number of being dialed, add and dial some access code that configures, and selects different communication service levels.Whether the called number that the caller network equipment is dialed through detection calling terminal user adds to dial and connect into prefix or add has been dialled for which access code prefix, correspondingly the communication service network between selection and the called network equipment.For example; When calling terminal 21 is directly dialed called number; Then the Calling Side network equipment 22 is dredged this call proceeding, promptly after the call request that receives calling terminal 21 to the communication network that carries based on TDM (or claiming circuit-switched network); For this time conversation, the communication service network between the Calling Side network equipment 22 and the callee side network equipment 26 is a circuit-switched network 23; When adding, calling terminal 21 dialled some access codes as prefix when dialing called number; Then the Calling Side network equipment 22 is after the call request that receives calling terminal 21; To dredge this call proceeding to adding the corresponding communication network that carries based on Packet Based Network (IP network or ATM net etc.) of the access code prefix of dialling with 21 of calling terminals; Promptly; For this time conversation, the communication service network between the Calling Side network equipment 22 and the callee side network equipment 26 just is based on the communication network that Packet Based Network is carried, and adds when dialling called number when having dialled first kind of prefix this call proceeding to dredging based on the communication network 124 of Packet Based Network carrying; Add when dialling called number when having dialled second kind of prefix this call proceeding is routed to terminal called 27 to dredging based on the communication network 225 of Packet Based Network carrying.Because different communication service networks possibly have different telecommunication service qualities, this is in fact making the calling subscriber can select the communication service levels of this conversation through different dial mode (before called number, whether add dial and connect into prefix, add group which access code prefix).Situation about providing by same communication network for the communication service between the Calling Side network equipment and the callee side network equipment; If this communication network has the ability that the different brackets communication service is provided, also can select the communication service levels of this conversation through this method calling subscriber.
The defective that this technology exists is that behind the call setup, the communication service levels of this time calling out has also just been confirmed; If the user wants to change the communication service levels of this conversation; Just must finish conversation this time, initiate communication request again, could change communication service levels; Therefore, can't satisfy the demand of user's temporary changes communication service levels in communication process.
Summary of the invention

Embodiment
Fig. 3 dials the flow chart of the embodiment of toll telephone for the present invention is applied to use landline telephone; Suppose that communication service levels is provided with mandarin sound quality and senior speech quality two-stage; The special number of dialling operator's setting changes to current talking as 333 senior; If do not dial, then being defaulted as is regular grade, and network side is carried out the mandarin sound quality.Dialling 333 change communication service levels specifically realizes through following steps:
Step 101: caller dials 333 is sent the request message of the current communication service levels of change in the communication process to network side; The user can dial in this number one by one, also can this number be arranged to a certain button, and the user only need can report the request of change communication service levels through phone by this button to network side;
Step 102: this Calling Side core net or switching network received 333 o'clock, learn this user request current talking is changed into senior, two steps below selecting the messaging parameter value that is complementary with the high grade of service and generate that execution command is concrete to carry out:
Step 1021: the value of the messaging parameter that Calling Side core net or switching network are selected according to the corresponding relation between the value of predefined communication service levels of network side and messaging parameter to be complementary with the advanced communications services grade; Suppose that the corresponding chnnel coding type of regular grade is the arrowband coding; The corresponding chnnel coding type of advanced communications services grade is a wideband encoding; The chnnel coding type setting of so current communication be arrowband coding; To current communication service levels be changed into senior speech quality, then select the wideband encoding that is complementary with it;
Step 1022: Calling Side core net or switching network generate the execution command that the chnnel coding type is set to wideband encoding;
Step 103: caller core net or switching network are changed into wideband encoding with the caller network equipment of current communication and the type of coding of the channel between the called network equipment by the arrowband coding according to execution command; Thereby the communication service levels of this conversation is changed into the senior speech quality of user's request, and the user has just enjoyed high-quality communication service like this.
Step 104: finish.
In addition; When landline telephone is not necessarily supported the wideband encoding of channel, during the type of coding of caller core net selective channel before generating said fill order, also further from network, obtain the ability parameter of this phone; As whether support wideband encoding of channel etc.; Judge whether this phone supports wideband encoding, if then generate fill order; Otherwise, carry out said step 104.
Wherein, can also change communication service levels through the priority that different call admits and the messaging parameters such as code rate of voice are set.
Need to prove; Calledly also can be used as the requesting party sends the request of communication service levels from this conversation of change to network side; Send when request when called; After all callers in the above-mentioned steps and the network equipment thereof and the called and network equipment carry out role exchange, also can realize changing the communication service levels of current talking.
Fig. 4 is applied to use the flow chart of the embodiment that mobile phone converses for the present invention; With a UMTS (Universal Mobile Telecommunications System-UMTS) net is the application scenarios of example; Suppose that dialling 666 can change to senior speech quality with current talking, the communication service levels that network side provides is senior, otherwise; Current talking is the mandarin sound quality, and the communication service levels that network side provides is a regular grade.The communication service levels of caller in this conversation is changed to senior, idiographic flow is following:
Step 201: caller dials 666 is initiated the communication service levels request message of change current talking in the conversation to network side; Dial in 666 one by one; Perhaps portable terminal is provided with the menu or the button of the configurable communication grade of service, and the user only need select to click advanced communications services scalar item or the button in the menu;
Step 202: the MSC server of this caller received 666 o'clock, discerned, detect the calling terminal request current talking is changed into senior, two steps below selecting the messaging parameter value that is complementary with the high grade of service and generate that execution command is concrete to carry out:
Step 2021: Calling Side MSC server selects the value of messaging parameter according to the corresponding relation of the value of predefined senior speech quality of network side and messaging parameter; Suppose that the corresponding channel coding rate of regular grade is 10kbps; The corresponding channel coding rate of advanced communications services grade is 20kbps; The channel coding rate setting of so current communication be 10kbps, current communication service levels is changed into senior speech quality, then select the code rate 20kbps be complementary with it;
Step 2022: the code rate of the current channel of Calling Side MSC server generation is set to the execution command of 20kbps;
Step 203: Calling Side MSC server passes to Calling Side radio network controller (RNC) through Rate control message execution command;
After step 204:RNC receives execution command; The channel coding rate of current talking is changed into 20kbps by 10kbps; Again for caller distributes the radio channel resource in this conversation, the calling terminal user as the requesting party has just obtained desired speech quality like this;
Step 205: finish.
When calling terminal is not necessarily supported the channel coding rate of 20kbps; When the caller core net was selected the code rate of said channel before generating said fill order; Also further from network, obtain the ability parameter of this portable terminal,, judge whether this portable terminal supports the channel coding rate of 20kbps as whether supporting channel coding rate of 20kbps etc.; If then generate fill order; Otherwise, carry out said step 205.
When this converses at same call control server such as MSC server; And further called communication service levels in this conversation is also risen to when senior in the lump, said step 203 is specially: the wireless access network equipment RNC that MSC server will execute instruction and pass to calling and called respectively; At this moment, step 204 is: caller RNC and called RNC with in the current talking separately the channel coding rate between user-network interface change into 20kbps by 10kbps, the calling and called both sides' of current talking communication clothes are equipped with grade and all change into senior like this.
When a plurality of call control servers such as MSC server were crossed in this conversation, the MSCserver of caller was according to the Different Strategies of business realizing, and whether decision is to the communication service levels of called MSC server notice caller request; In general; If terminal called and calling terminal belong to a UMTS net together, though or belong to heterogeneous networks and have the interworking between network ability of communication QOS, in this case; As shown in Figure 5, between step 204 and step 205, continue to carry out following steps:
Step 206: the WMG that the MSC server of Calling Side passes through to be controlled (Media Gateway is called for short MGW) sends Rate Control message directly to the execution command of the notifying changed current channel coding rate of the MSC of callee side server through Nb interface;
Step 207: the MSC server of callee side passes to callee side RNC with this parameter after detecting execution command in Rate Control message;
Step 208: callee side RNC carries out and should instruct; Channel coding rate between the callee side user-network interface in the current talking is changed into 20kbps by 10kbps; Redistribute called radio channel resource in this conversation, make the terminal called user also obtain the communication service levels of equal speech quality.
Network-Network interface between the calling and called terminal not necessarily has the interworking between network ability of communication QOS; And/or when requesting party's user-network interface does not necessarily have the ability of the communication service levels of providing; Also further comprise step between said step 204 and the step 206: caller MSC server need judge and called network equipment between the communication network interworking between network ability of communication QOS whether; And whether called user-network interface has the ability of the communication service levels of providing; If then execution in step 206, otherwise execution in step 205.
When said terminal called is not necessarily supported the channel coding rate of 20kbps; Also further comprise between said step 206 and the step 207: the MSC server of callee side obtains the ability parameter of terminal called; Judge whether terminal called has the ability of the channel coding rate of supporting 20kbps; If carry out said step 207; Otherwise, carry out said step 205, called communication service levels remains unchanged.
The priority of code rate that wherein, can also be through priority that different call admits and/or voice are set or the code rate of type and/or channel or type and/or call acceptance and/or the forwarding priority of packets of voice bag and the value that abandons the sequential scheduling messaging parameter thereof change communication service levels.
Need to prove; Calledly also can be used as the requesting party sends the request of communication service levels from this conversation of change to network side; Send when request when called; After all callers in the above-mentioned steps and the network equipment thereof and the called and network equipment carry out role exchange, also can realize changing the communication service levels of current talking.
The present invention can dial in different special numbers according to the terminal through network side in conversation; The change communication service levels; Can be applied to based on Bearer Independent Call Control Protocol Tandem network of IP-based switching, based on the SIP/SIP-T softswitch tandem network, realize the communication service levels of change toll telephone; Also can be applied to fixedly IP-based switching net, realize the communication service levels of change VoIP based on Session Initiation Protocol or the access of H248 agreement; Can also be applied to SGPP IMS net, the communication service levels of change SIP.Perhaps according to by CDMA terminal, WCDMA terminal, WiFi terminal, WiMax terminal different current service grade marks being set, the user can change the communication service levels of selecting CDMA conversation, WCDMA conversation, WiFi telephone relation or WiMax telephone relation.
It should be noted last that: above embodiment is only in order to explaining technical scheme of the present invention, but not the present invention is made restrictive sense.Although the present invention is specified with reference to above-mentioned preferred embodiment; Those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement technical scheme of the present invention, and this modification or be equal to spirit and the scope that replacement does not break away from technical scheme of the present invention.
