401: terminal is to the access point _ 1 initiating business request message of micro base station network;
Wherein, described business request information comprises terminal iidentification, type of service and QoS of survice demand;
Wherein, the reflection of described QoS of survice demand is the requirement of the other network congestion to accessing network of different service priority of described terminal.
402: service management control centre receives described business request information;
Wherein, it is wireless access network gateway by side, described micro base station network access point _ 1 that described service management control centre receives described business request information, and the described business request information described terminal initiated sends to described service management control centre.
403: service management control centre carries out authentication according to described business request information to described terminal;
Wherein, describedly according to described business request information, authentication is carried out to described terminal, specifically comprises:
Judge that whether the identity of described terminal is legal; And judge whether described terminal has the ability of being served by other collaborative access nodes, if judge that described terminal identity is legal but not there is the ability of being served by other collaborative access nodes, then perform 409; If judge that described terminal identity is legal and there is the ability of being served by other collaborative access nodes, then perform 404.
Optionally, describedly judge that whether the identity of described terminal is legal, specifically comprise: when service management control centre receives the business request information of described terminal, according to the described terminal iidentification in described business request information, mobile switching centre (the Mobile SwitchingCenter of service management control centre and core net, be called for short MSC)/VLR Visitor Location Register (Visitor Location Register, be called for short VLR) carry out Signalling exchange, the MSC/VLR of core net store allow the identification information of all terminals accessed, if the described terminal of current access be identified in the MSC/VLR of core net, then show that the identity of described terminal is legal, otherwise the identity of described terminal is illegal,
Optionally, describedly judge whether described terminal has the ability of being served by other collaborative access nodes, specifically comprise: service management control centre also have recorded whether described terminal can be carried out service distributing information by other collaborative access nodes, such as, described information is type of service, optional is session, Streaming Media etc., if the type of service of described terminal meets the described type of service can being carried out service distributing by other collaborative access nodes of record, then show that authentication passes through, otherwise failure.
404: service management control centre obtains the signing QoS information of described terminal from core net, according to the described business request information obtained from described terminal, and the signing QoS information of described terminal, the priority level of described terminal traffic is adjudicated;
Wherein, attaching position register (the Home Location Register of described core net, be called for short HLR) in can record the signing QoS information of terminal, such as record the identification information of terminal and the corresponding relation of signing QoS information, according to the identification information of the terminal of carrying in this corresponding relation and business request information, service management control centre can obtain corresponding signing QoS information.
Wherein, the signing QoS information of described terminal reflects the grade of service of described terminal, such as gold class 1, silver medal grade 2, bronze medal grade 3.
Optionally, after the signing QoS information of acquisition, can also be other according to the service priority of signing QoS information and type of service determination terminal.Such as, according to the type of service of described terminal, the priority of the type of service of described terminal is divided into conversation class a from high to low, Streaming Media class b, interactive class c and background class d, signing QoS information comprises the grade of service of terminal, then other judgement of service priority of described terminal is the information of priority two aspect of the grade of service of comprehensive described terminal and the type of service of described terminal, described service priority can not obtain according to the priority combination sequence of the type of service of the grade of service of described terminal and described terminal, then described service priority is not from high to low: 1a, 1b, 1c, 1d, 2a, 2b, 2c, 2d, 3a, 3b, 3c, 3d.
405: service management control centre is according to the other and described QoS of survice demand of the described service priority of described terminal, and the network congestion of micro base station network access point _ 1 of current access, can micro base station network access point _ 1 of adjudicating current access meet the business demand of described terminal;
Wherein, described network congestion refers to the load information of network, specifically can be the service traffics that described network carries, and described network congestion judges according to congestion threshold value, and wherein said congestion threshold value can customize.If described offered load has exceeded described congestion threshold value, then show that the described micro base station network access point 1 of current access is congested, otherwise show that described micro base station network access point _ 1 of current access is not congested, usual described network congestion represents with percent value.
Wherein, the business demand that can micro base station network access point _ 1 of the current access of described judgement meet described terminal is carried out comprehensively, quantizing the requirement of the network congestion of micro base station network access point _ 1 of current access at the priority of the grade of service of the described terminal given by 404 and the type of service of described terminal.
Wherein, the different type of service of terminal has different priority levels, the difference of priority level then causes the demand to channel (i.e. congestion situation) to be also different, the business that priority level is high, then require stricter, the business that priority level is relatively low to the congestion situation of network, then the congestion situation of network is required to be not just also very strict, as terminal sends mail service, then allow certain time delay, therefore just requiring to the congestion situation of network is not very strict; The business of terminal uploading pictures, terminal requires just high to time delay, wish that delay can not be oversize, therefore the different type of service of terminal and priority level thereof can be passed through, the access base station matched for the service selection network congestion of terminal carries out business transmission, can improve the utilization rate of system transmission resources.
Such as, judge whether current access base station meets business demand, is specially: for Gold Subscriber, if offered load is more than 80% according to the grade of service of described terminal and network congestion, then definition can not meet business demand; For Silver Subscriber, if offered load is more than 90%, then definition can not meet business demand; For Bronze Subscriber, if offered load is more than 95%, then definition can not meet business demand.
Again such as, according to described terminal service priority not and network congestion judge whether the current access base station of terminal traffic meets business demand, for be all gold class 1 terminal different types of service required by offered load ability also different, for conversation class a, Streaming Media class b, interactive class c and background class d, be specially: for gold class 1 conversation class a(1a), if offered load is more than 70%, then definition can not meet business demand; For gold class 1 Streaming Media class b(1b), if offered load is more than 73%, then definition can not meet business demand; For gold class 1 interactive class c(1c), if offered load is more than 76%, then definition can not meet business demand; For gold class 1 background class d(1d), if offered load is more than 80%, then definition can not meet business demand.For the type of service of the different priorities of the grade of service corresponding to silver medal grade, bronze medal grade of described terminal, there is the similar requirement to network congestion.Therefore, when the grade of service of described terminal is different, described terminal has different requirements to network congestion; When the grade of service of described terminal is identical, but for the different type of service of described terminal, according to the priority of described terminal traffic type, not identical to the requirement of the congestion situation of network yet.
Wherein, if according to the other and described QoS of survice demand of the described service priority of described terminal, and the network congestion of micro base station network access point _ 1 of current access can meet the business demand of described terminal, then perform 409, transmitted by the business of access point _ 1 to described terminal of micro base station network; If can not meet, then perform 406;
406: the radio network controller of service management control centre and macrocellular network and the wireless access network gateway of micro base station network carry out alternately, obtain access point _ 2 in base station _ 1 in macrocellular network and micro base station network and carry out the network congestion of business transmission;
407: the judgement of service management control centre carries out by access point _ 2 in base station _ 1 in described macrocellular network or micro base station network the business demand whether business transmission meets described terminal;
Wherein, it is also judge according to the determination methods given by 405 that the judgement of described service management control centre carries out by access point _ 2 in base station _ 1 in described macrocellular network or micro base station network the business demand whether business transmission meet described terminal, specifically according to the grade of service of described terminal and the present type of service of described terminal, and the network congestion that in base station _ 1 in the described macrocellular network obtained and micro base station network, business transmission is carried out in access point _ 2 carries out judging, specific implementation, according to the method given by 405, repeats no more herein.
Wherein, if can not meet the business demand of described terminal, then the SGSN of service management control centre notice core net, then SGSN and described terminal carry out the grade of service that QoS consults to reduce described terminal, such as, are reduced to 2a by 1a.Then the information by SGSN, namely described negotiation result being reduced a grade of service of described terminal returns to service management control centre, performs 409 afterwards; If the business demand of described terminal can be met, then perform 408.
408: service management control centre optimal one of access point _ 2 selective channel condition from base station _ 1 described macrocellular network and micro base station network carries out business transmission;
Wherein, described selective channel condition is optimal is from base station _ 1 described macrocellular network and described micro base station network, select network congestion to be worth minimum that in access point _ 2.Specifically, be that offered load is the lightest, minimum that of the service traffics also namely carried.
