Embodiment
In the research and practice process to prior art, the present inventor finds, HNB can only be known Iuh interface and Uu interface resource situation, can only distribute/revise Iuh and the Uu carrying of RAB, can't finish the distribution of Iu carrying/modification.The Iu carrying that can cause like this its Iuh carrying that distributes/revise to distribute with HNB GW/revise is not mated.In addition, HNB is when distribution/modification Iuh resource, can only know that from the RAB request CN resource can satisfy the QoS of RAB request, can't know the current disposal ability situation of HNB GW (comprising Iuh interface and Iu interface), therefore can't distribute/revise the Iuh resource that meets HNB GW disposal ability.
For this reason, the invention provides following examples.
Various embodiments of the present invention relate to the first equipment and the second equipment, and wherein, the first equipment can be HNB, and correspondingly, the second equipment then is HNB GW, and similarly, the first equipment can also be HNB GW, and the second equipment then can be HNB.
Below in conjunction with accompanying drawing each embodiment is described in detail.
Fig. 1 is the realization flow figure of first embodiment of the invention, the corresponding following steps of this embodiment:
By above-mentioned processing, can be so that HNB and HNB GW can use the qos parameter that satisfies the RAB load bearing requirements to carry out the distribution of RAB carrying/modifications, so that the each several part of RAB in carrying is mutually harmonious.
The qos parameter of determining in the abovementioned steps 101, minute qos parameter at the beginning of specifically can determining one by the second equipment according to the interface resource situation of this equipment first, the interface resource situation that should just be divided again qos parameter and this first equipment by the first equipment basis, definite qos parameter that finally meets the requirement of RAB carrying.
And as previously mentioned, the first equipment can be HNB, and correspondingly, the second equipment can be HNBGW then, and vice versa.Because the processing of both of these case is basic identical, be HNB with the first equipment mainly below therefore, the second equipment is that the situation of HNB GW is that example is described in detail.
Second embodiment of the invention mainly is the qos parameter in the RAB assignment messages that is sent according to interface resource situation and the CN of this equipment first by HNB GW, determines just minute qos parameter, is determined the qos parameter of the final requirement that meets the RAB carrying by HNB again.As shown in Figure 2, the corresponding following steps of second embodiment of the invention:
Qos parameter in the RAB assignment messages that step 201, HNB GW send according to interface resource situation and the CN of this equipment is determined just minute qos parameter, and is sent to HNB.
For the function that realizes that RAB in the HNB scene sets up, CN can according to user's CAMEL-Subscription-Information, professional itself, the QoS that requires etc. is for the RAB that will set up selects a qos parameter, and carrying this qos parameter in the RAB assignment messages that sends to HNB GW.This qos parameter generally includes maximum bit rate (MBR), can also comprise that optional parameters guarantees bit rate (GBR), service priority etc.
In addition, this RAB assignment messages specifically can be RAB foundation/modify request messages, and then this qos parameter specifically can be set up at RAB/carry in the RAB parameter of modify request messages.
HNB GW can determine whether to revise qos parameter according to the current resource situation of this HNB GW after receiving the RAB assignment messages that CN sends, and a determined just minute qos parameter is sent to HNB by the RAB assignment messages.
In this step, HNBGW can be according to the situation of own resource, judges that this HNBGW is current whether to satisfy the required QoS of RAB and ensure.Such as, if the current Iu interface resource of this HNB GW does not reach MBR, but can satisfy GBR, then can reduce the MBR in the qos parameter.Certainly, if current resource can satisfy MBR, namely be higher than MBR, then do not need to revise qos parameter.Certainly, this HNB GW can also consider Iu interface resource and Iuh interface resource simultaneously,, if these two interface resources all do not reach MBR, but all can satisfy GBR that is, then can reduce the MBR in the qos parameter; If all can satisfy MBR, then do not need to revise qos parameter.If without the GBR requirement, HNB GW can be according to resource situation etc. so, and its maximum that can provide is provided in the RAB assignment messages, and with this maximum as the first MBR of minute QoS.
If current resource GBR does not reach, the further processing that then needs the selection such as priority level, queue capability according to this RAB to carry out, such as, if current business is demand service, can not line up, then HNB GW can directly refuse this business; If the priority of current business is lower, and non-demand service, HNB GW can rank to this business so; If the priority of current business is very high, and need to carry out immediately, HNB GW can set up RAB for this business by the resource of seizing other carrying so, in this case, HNB GW need to determine whether to revise qos parameter equally, and determined qos parameter sent to HNB by the RAB assignment messages, and follow-up processing is as described in the following step.
The interface resource situation of mentioning in the various embodiments of the present invention mainly refers to the data retransmission ability that this interface can provide, can be according to the disposal ability of the equipment that this interface is provided self, and the current available factors such as the network bandwidth determine.Wherein, the disposal ability of equipment self can be dispatching, buffer memory ability etc.
If the interface resource of the Uu of HNB and Iuh all can satisfy the MBR that just divides in the qos parameter, then this HNB can directly distribute Uu carrying and Iuh carrying according to this MBR; If the interface resource of the Uu of HNB and Iuh can not satisfy the MBR that just divides in the qos parameter, but can satisfy GBR, then this HNB can select a numerical value between MBR and the GBR, and distributes/revise Uu carrying and Iuh carrying according to this numerical value.If just divide in the qos parameter without the GBR demand, so just according to value less than MBR of resource situation selection.
And if the interface resource of the Uu of HNB and Iuh all can not satisfy the GBR that just divides in the qos parameter, then this HNB can not distribute/revise Uu carrying and Iuh carrying.In this case, similar with abovementioned steps 201, the further processing that HNB also can carry out according to selections such as the priority level of this RAB, queue capability.
Specifically, HNB can carry out the distribution that Uu carries and Iuh carries/modification according to determined qos parameter, and this qos parameter fed back to HNB GW, HNB GW then carries out the distribution of Iu carrying/modification according to this qos parameter, and can further include the configuration of Iuh downlink bearing.Wherein, HNB can feed back to HNB GW with this qos parameter by the response message of RAB assignment messages.
In addition, HNB GW is distributing/is revising after the Iu carrying, can also return a RAB to CN and assign response message.
Pass through above-mentioned steps, so that HNB is at definite qos parameter and before distributing/revise Uu carrying and Iuh carrying, can learn the first minute qos parameter corresponding with the Iu interface resource operating position of HNB GW, thereby can carry out the distribution that Uu carries and Iuh carries/modification in conjunction with the Iu interface resource operating position of HNB GW, so that the Uu carrying that HNB distributes/revises and Iuh carrying, identical qos parameter is used in the Iu carrying that distributes with HNB GW/revise, and is mutually harmonious for the RAB carrying of each interface assignment/modification.
The first equipment among above-mentioned the second embodiment is HNB, and the second equipment is HNB GW.If the first equipment is HNB GW, the second equipment is HNB, so, in the above-mentioned steps 201, by the resource situation of HNB according to Iuh interface and the Uu interface of this equipment, and the qos parameter in the RAB assignment messages of CN transmission, determine just minute qos parameter, and send to HNB GW, wherein, the RAB assignment messages that CN sends receives and is transmitted to HNB by HNB GW.In addition, HNB sends just minute qos parameter to HNB GW, specifically can send by distribute/revise the request message message, the address binding message such as resource.Here two message mentioning are example, can also be other message such as the Iu resource request message.And HNB sends in the request message of HNB GW can also carry HNB DL address, CNUL address etc., so that HNB GW knows the destination address of the downlink data of RAB carrying, and up destination address, the data in this carrying correctly are routed to the destination.
Correspondingly, in the above-mentioned steps 202, then by the Iu interface resource situation of HNB GW according to first minute qos parameter receiving and this HNBGW, determine to meet the qos parameter of RAB load bearing requirements, certainly, in this step, HNB GW can also further carry out determining of qos parameter according to the resource situation of Iuh interface.In the above-mentioned steps 203, the qos parameter that HNB GW then needs to determine sends to HNB.
Among above-mentioned the second embodiment, HNB or HNBGW can also carry out the distribution of interface bearing/modifications according to this qos parameter, behind the qos parameter of finally being determined, again according to adjusting by final definite qos parameter after having determined just minute qos parameter.
Third embodiment of the invention mainly is by the interface resource situation of HNB according to this equipment, and the interface resource situation of HNBGW determines to meet the qos parameter of the requirement of RAB carrying.As shown in Figure 3, the corresponding following steps of third embodiment of the invention:
Step 301, HNB obtain the relevant information of the interface resource situation of HNB GW.
The relevant information of the interface resource situation of this HNB GW that HNB receives specifically can be the interface resource situation of this HNBGW, can also be the Maximum Bit Rate that the interface resource situation of this HNB GW can satisfy.
And the relevant information of this interface resource situation specifically can be HNB GW transmitting the RAB assignment messages that CN sends to HNB when, transmits by this RAB assignment messages.In this case, HNBGW is after receiving the RAB assignment messages that CN sends, and just the relevant information of the interface resource situation of self is sent to HNB's.
If what HNB received is the interface resource situation of HNB GW, then HNB can also directly obtain the interface resource situation of this HNB GW by the Resource Exchange request message of HNB GW transmission; Can also send the Resource Exchange request message to HNB GW, and obtain the interface resource situation of this HNB GW by the response message that HNB GW returns; Can also be to obtain by the message that HNB GW regularly sends to HNB.For this situation, HNB just can obtain the relevant information of the interface resource situation of this HNB GW before HNB GW receives the RAB assignment messages that CN sends.
In addition, as previously mentioned, the interface resource situation of this HNB GW should comprise the resource situation of Iu interface at least, can further include the resource situation of Iuh interface.Correspondingly, the Maximum Bit Rate that the interface resource situation of this HNB GW can satisfy can draw according to the resource situation of Iu interface, also can draw according to the resource situation of Iu interface and Iuh interface.
Step 302, HNB be according to the interface resource situation of this HNB, and the relevant information of the interface resource situation of the HNB GW that obtains, and the qos parameter in the RAB assignment messages that sends of CN determine to meet the qos parameter of RAB load bearing requirements.
If what obtain by step 301 is the interface resource situation of this HNB GW, so, in step 302, whether the resource situation of interface of interface, the HNB GW of this HNB of can judging HNB all can satisfy the qos parameter that carries in the RAB assignment messages that CN sends, namely can satisfy the MBR in this qos parameter, if can satisfy, can determine that then the qos parameter that carries in the RAB assignment messages is the qos parameter that meets the RAB load bearing requirements.Do not satisfy this MBR if having one in the interface of the interface of HNB, HNB GW at least, and total interface all satisfies the GBR in the qos parameter, so, can reduce this MBR, and with amended qos parameter as the qos parameter that meets the RAB load bearing requirements.
If what obtain by step 301 is the Maximum Bit Rate that the interface resource situation of this HNB GW can satisfy, so, in step 302, HNB can judge the interface of this HNB and the Maximum Bit Rate that HNB GW can satisfy, whether all can satisfy the qos parameter that carries in the RAB assignment messages of CN transmission, namely can satisfy the MBR in this qos parameter, if can satisfy, can determine that then the qos parameter that carries in the RAB assignment messages is the qos parameter that meets the RAB load bearing requirements.Do not satisfy this MBR if having one in the Maximum Bit Rate of the interface of HNB and HNB GW at least, and all satisfy the GBR in the qos parameter, so, then can reduce this MBR, and with amended qos parameter as the qos parameter that meets the RAB load bearing requirements.
Wherein, as previously mentioned, the interface of this HNB generally includes Iuh interface and Uu interface.
Step 303, HNB and HNB GW be according to the determined qos parameter of step 302, carries out the distribution of RAB carrying/modification.
The processing of this step 303 and abovementioned steps 203 are similar, therefore repeat no more here.
Set up the RAB carrying by above-described embodiment or other modes after, also can need to discharge the RAB carrying because of a variety of causes.Specifically can be by initiations such as HNB GW, HNB and CN.
For situation about being initiated by CN, CN can initiate RAB and discharge when determining to discharge the RAB resource based on certain reason.Its reason can be service ending, can also be to receive releasing request that HNB or HNB GW send etc.The concrete dispose procedure of the 4th embodiment as shown in Figure 4, corresponding following steps:
This message is transmitted to HNB by HNB GW usually.
As previously mentioned, CN can be after receiving the releasing request that HNB or HNB GW send, and initiates to discharge.
CN can also be based on the initiation of HNB GW or HNB and is sent RAB releasing request message.
For situation about being initiated by HNB GW, when HNB GW resource situation changes, can trigger RAB and discharge indication.In addition, if HNB GW can obtain the resource situation of HNB, then HNBGW also can according to the situation of change of the resource situation of HNB, determine whether to initiate the release of RAB resource.Such as, when HNB GW determined that the interface resource situation changes, HNB GW can directly initiate RAB releasing request message to CN.HNB GW can also send association request message to HNB, send RAB releasing request message by HNB to CN again, and this RAB releasing request message can be transparent to CN by HNB GW.The interface resource situation of HNB GW changes, and specifically can be that Iu interface resource situation changes, and also can be that Iuh interface resource situation changes.
Similarly, for situation about being initiated by HNB, when the resource situation of HNB changes, can trigger RAB and discharge indication.Similar equally, if HNB can obtain the resource situation of HNB GW, then HNB also can according to the situation of change of the resource situation of HNB GW, determine whether to initiate the release of RAB resource.Such as, when HNB determines that the Iuh interface of this HNB or Uu interface change, perhaps, if HNB can be known the interface case of HNB GW, can also when HNB determines that the Iu interface of HNB GW or Iuh interface change, send RAB releasing request message to CN.
As previously mentioned, HNB GW needs this message is transmitted to HNB.And HNB GW can be first to this message of HNB transparent transmission, after the RAB carrying during perhaps this arranges in release, again to this message of HNB transparent transmission.
HNB can directly discharge Iuh and the Uu carrying of this equipment after receiving RAB releasing request message.
HNB can also send first a release request message to HNB GW after receiving RAB releasing request message, HNB GW then can return one to HNB and discharge response message, perhaps sends releasing request message to HNB.HNB then after receiving release response message or releasing request message, discharges Iuh and the Uu carrying of this equipment again.
HNB also can send RAB to CN by HNB GW and discharge response message after discharging Iuh and Uu carrying.If HNB GW passes through HNB in the RAB releasing request message that just CN is sent before, so, HNB GW also should after receiving that HNB sends to the RAB release response message of CN, discharge the interface bearing in this equipment.
By above-mentioned steps, can be so that HNB and HNB GW can discharge RAB when carrying at needs, successfully discharge the RAB carrying in the equipment separately.
