Specific embodiment
The technical solution of the present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
The present invention ensures that the basic thought of femtocell user service quality is：CSG user's initiating business request, works as family
When the available interface-free resources of base station can not meet the distribution bandwidth of CSG user, select from the user of currently used Home eNodeB
The user that QoS degradations are processed can be carried out, QoS degradation process is carried out.
If the available interface-free resources of Home eNodeB disclosure satisfy that the distribution bandwidth of CSG user, CSG user accesses described
Home eNodeB.
Wherein, during CSG user's initiating business request, in addition it is also necessary to formulate corresponding qos policy for the CSG user, including：With
Family QoS grades and the distribution bandwidth of user.
When the available interface-free resources of Home eNodeB can not meet the distribution bandwidth of CSG user, need to judge currently used family
With the presence or absence of the user that can carry out QoS degradation process in the user of front yard base station：If deposited in the user of currently used Home eNodeB
In non-CSG user and non-CSG user can carry out QoS degrade process process when, then judge the user of currently used Home eNodeB
Middle presence can carry out the user that QoS degradations are processed.
So-called QoS degradations are processed as：The distribution bandwidth of the user is reduced, accordingly, further can also be dropped
Low user QoS grades.
Then determine that non-CSG user can carry out QoS degradations process process, specially：Reduce the distribution bandwidth of non-CSG user
Bandwidth afterwards, disclosure satisfy that the business demand of non-CSG user.
In order to realize said method, the invention provides guarantee femtocell user service quality as shown in Figure 1 is
System, including：Home eNodeB, PRCF and Home eNodeB policy module, wherein：
Home eNodeB, for when CSG user's initiating business request, judging whether the available interface-free resources of itself can meet
The distribution bandwidth of CSG user, it is impossible to when meeting, notifies PRCF；
PRCF, for when CSG user's initiating business request, being that CSG user formulates corresponding qos policy, including：User
QoS grades and the distribution bandwidth of user；It is additionally operable to the distribution band of CSG user is met in the available interface-free resources of Home eNodeB
When wide, notifying that Home eNodeB policy module whether there is in judging the user of currently used Home eNodeB can be carried out at QoS degradations
The user of reason；The user for being additionally operable to process to QoS can be carried out to degrade carries out QoS degradation process.
Home eNodeB policy module, for receiving after the notice of PRCF, in the user for judging currently used Home eNodeB be
No presence can carry out the user that QoS degradations are processed：There is non-CSG user and non-in the user for determining currently used Home eNodeB
When CSG user can carry out QoS degradation process, existing in the user for judging currently used Home eNodeB can be carried out at QoS degradations
The user of reason；And select to carry out the user that QoS degradations are processed from the user of currently used Home eNodeB, report PRCF.
With reference to the system of Fig. 1, femtocell user service quality is ensured to the present invention by specific embodiment
Scheme be specifically described.
For Home eNodeB is operated in the scene of mixed model, if the interface-free resources anxiety of Home eNodeB cannot meet
During the service request of CSG user, it is responsible for redistributing the interface-free resources of Home eNodeB by core net, as shown in Fig. 2
Comprise the steps：
Step 201, after certain user's initiating business request of Home eNodeB, PCRF formulates corresponding QoS for the user
Strategy.The content of qos policy includes：Distribution bandwidth of user QoS grades and user etc..
Wherein, user QoS grades are referred to：The business that PCRF is currently initiated based on the user, is that the user formulates accordingly
QoS grades；Distribution bandwidth is referred to：PCRF is based on the bandwidth that business data flow is user's distribution.
Step 202～203, Home eNodeB can determine that current available interface-free resources according to loading condition, and judgement can
Whether the distribution bandwidth of active user disclosure satisfy that with interface-free resources, if not, execution step 203, Home eNodeB will be eated dishes without rice or wine money
The inadequate message in source and PCRF can be reported with interface-free resources, then execution step 204；If it is, execution step 209, should
User's access to family base station, carries out business transmission.
Step 204, judges whether the user of current initiating business request is CSG user, if it is, execution step 205；Such as
Really no, execution step 210, Home eNodeB refuse the service request of the user, notify which switches over, and inform switching reason.
PCRF receives the inadequate message of interface-free resources and can notify that Home eNodeB policy module is looked into after interface-free resources
The identity category of the user of current initiating business request is ask, confirms whether which is CSG user.
If the user of current initiating business request is non-CSG user, now execution step 210, PCRF notifies to send out
The user for playing service request switches over, and informs switching reason (i.e. Home eNodeB refuses the service request of the user).
Step 205, whether there is the use that can carry out that QoS degradations are processed in judging the user of the currently used Home eNodeB
Family, if it has, execution step 206；If it did not, execution step 210, the service request of the current CSG user of Home eNodeB refusal,
Notify which switches over, and inform switching reason.
So-called QoS degradations process and are primarily referred to as reducing the bandwidth for distributing to user, accordingly, it is also desirable to reduce the use correspondence
QoS grades.
If Home eNodeB policy module determines that the user of current initiating business request is CSG user, further, family
The identity category of the user of the currently used Home eNodeB of front yard base station policy module query, if wherein exist non-CSG user and
Non- CSG user can carry out QoS degradations process process, then it is assumed that existing in the user of the currently used Home eNodeB to be carried out
The user that QoS degradations are processed.
It is pointed out that carrying out needing to meet a precondition when QoS degrades and processes, i.e.,：Carry out at QoS degradations
After reason, need to ensure the seriality of degraded non-CSG customer services；If non-CSG user can not after carrying out QoS degradation process
Ensure the seriality of its business, then determine that the non-CSG user is to be not available for the user that QoS degradations are processed.
The so-called seriality for ensureing degraded non-CSG customer services, is primarily referred to as the bandwidth energy after reducing distribution bandwidth
Enough meet the business demand of the non-CSG user.
Still can not if there is no non-CSG user in being currently in use the user of Home eNodeB or there is non-CSG user
Carry out QoS degradation process, then in thinking the user of the currently used Home eNodeB, there is no the use that can carry out that QoS degradations are processed
Family, now, execution step 310, Home eNodeB policy module can to PCRF return can not degrading user message, PCRF notice
User just in initiating business request switches over, and inform its switching reason (i.e. Home eNodeB refuse the user business please
Ask).
Step 206, Home eNodeB policy module select the user that can carry out that QoS degradations are processed, and carry out QoS drops by PRCF
Level is processed.
When Home eNodeB policy module selects to carry out the user of QoS degradation process, there is multiple choices principle：For example, if
There are multiple non-CSG users carries out business transmission using Home eNodeB simultaneously, then, Home eNodeB policy module will can take
The non-CSG reporting of user of one or more of large bandwidth is to PCRF；For example, if while there are multiple non-CSG users uses family
Base station carries out business transmission, then, Home eNodeB policy module can also be by using Home eNodeB time longer one or many
Individual non-CSG reporting of user is to PCRF.It is, of course, also possible to there is other to select.
When carrying out QoS degradation process, if Home eNodeB policy module has reported a non-CSG user, then PRCF can
To reduce the distribution bandwidth of the user；If Home eNodeB policy module has reported multiple non-CSG users, then PRCF can subtract
The distribution bandwidth of few this multiple non-CSG user.
Step 207, after the process of QoS degradations, Home eNodeB judges whether currently available interface-free resources disclosure satisfy that current CSG
The distribution bandwidth of user, if not, return to step 205；If it is, execution step 208, current CSG user's access family base
Stand, and set up service connection.
If after QoS degradation process is carried out to non-CSG user, the available interface-free resources of Home eNodeB can not still meet
The distribution bandwidth of CSG user, then return to step 205, continue to select other non-CSG users, and carry out at QoS degradations
Till reason, the service request until CSG user can be met, or no degrandable user.
As can be seen here, when the interface-free resources of Home eNodeB are inadequate, PCRF notifies that Home eNodeB policy module query is current
Using the identity category of the user of the Home eNodeB, and the identity category of the user of current initiating business request.
If the user of current initiating business request is CSG user, now there are two kinds of situations：First, currently used family
Base station there is non-CSG user in carrying out the user of business transmission and non-CSG user can carry out QoS degradations, then Home eNodeB plan
Module is omited by above-mentioned non-CSG reporting of user to PCRF, and then by PCRF to carrying out QoS degradation process, to meet the industry of CSG user
Business request.2nd, there is no the non-CSG of non-CSG user or presence in currently used Home eNodeB in carrying out the user of business transmission
User can not carry out QoS degradations, then Home eNodeB policy module to PCRF return can not degrading user message, now, PCRF
Notify CSG user's switching.
If the user of current initiating business request is non-CSG user, Home eNodeB policy module notifies PCRF, PCRF
Notify non-CSG user's switching.
Thus, can ensure that the service quality of CSG user, moreover it is possible to ensure to be currently in use the non-CSG of Home eNodeB as far as possible
The business continuance of user.
The above, only presently preferred embodiments of the present invention is not intended to limit protection scope of the present invention.
