And the communication unit 211 in the wireless resource management apparatus 21 can also be used for regularly and the regularly mutual network environment information of the access network of ownership each other of the wireless resource management apparatus 21 of at least one second access network.
Said system framework wherein, as shown in Figure 2, in the present embodiment, the access network that comprises two employing different radio standards with distributed heterogeneous communication system is that example is introduced, be called Access Network 1 and Access Network 2, correspondingly, the wireless resource management apparatus 21 that belongs to Access Network 1 and Access Network 2 respectively is called CRRM1 and CRRM2, generally, the access network of user terminal 20 acquiescences can be set up on their own according to the use habit of self by the user, in the present embodiment, the access network of user terminal 20 acquiescences is set to Access Network 1, and promptly user terminal 20 acquiescences belong to the CRRM1 management and control; And CRRM1 and CRRM 2 have realized the combination admission controlled function by information interaction between heterogeneous communication system.
In actual applications, distributed heterogeneous communication system can also comprise the Access Network that adopts different access technologies more than two, and present embodiment is that example is introduced with network environment shown in Figure 2 only.
Except that the above-mentioned functions entity, as shown in Figure 2, can also comprise in the distributed heterogeneous communication system:
The base station belongs to each Access Network, and the work flow that is used for being in IP backbone future is sent to user terminal 20, perhaps will mail to IP backbone from the Business Stream that removes user terminal 20;
Gateway is used to realize being connected of each Access Network and IP backbone;
The multimode terminal Correspondent Node is used for carrying out telecommunication with user terminal 20.
Consult shown in Figure 4ly, in the present embodiment, user terminal 20 is when inserting distributed heterogeneous communication system, and CRRM1 of its acquiescence ownership admits the detailed process of control as follows to it:
Step 400:CRRM1 receives the business request information that user terminal 20 sends, and carries traffic type information (comprising QoS of customer QoS demand at least) in this business request information.
In the present embodiment, user terminal 20 is given tacit consent under idle condition and is resided in the Access Network 1, so, when user terminal 20 is initiated new conversation request (sending new business request information) to CRRM1, the CRRM 1 of management Access Network 1 just admits control to user terminal 20, for the conversation request that user terminal 20 is initiated selects one or at least two to adopt the access network of different access technologies to insert.
On the other hand, in the present embodiment, user terminal 20 also carries the downlink channel condition information of each access network in the business request information that sends, downlink channel condition information be used to represent current downlink wireless channel link-quality (as, path loss), downlink channel condition information is measured by user terminal 20, and reports to CRRM1, and the up channel state information is measured by network side.In addition, user terminal 20 can also carry in business request information and be used to indicate self whether identification information of supporting business shunting, if the function that is subjected to user terminal 20 limits not supporting business and shunts, so, even the business of its request can be shunted, CRRM1 does not also carry out the admittance control of service distributing to it.
Step 410:CRRM1 judges according to default admittance strategy whether the type of service of user terminal 20 requests can be shunted; If then carry out step 420: otherwise, carry out step 470.
In the present embodiment, CRRM1 obtains default admittance strategy from policy library, and in conjunction with the traffic type information of carrying in the business request information this business is shunted judgement, for example:
If the type of service of user terminal 20 requests is the normal speech business, then directly carry out routine and admit control, need not to carry out service distributing;
If the type of service of user terminal 20 request is the have relatively high expectations video traffic, ftp business etc. of transmission bandwidth, then needs indicating user terminal 20 that the Business Stream of request is divided into many professional son streams, and transmit by a plurality of access networks;
Step 420:CRRM1 obtains the shunting advisory information that is complementary with traffic type information in policy library, the network environment information that obtains the network environment information of Access Network 1 in this locality and receive the Access Network 2 of CRRM2 transmission.
In the present embodiment, the default various shunting advisory information of corresponding each traffic type information are kept in the policy library, CRRM1 can obtain corresponding shunting advisory information according to the traffic type information of carrying in the business request information, and the content of shunting advisory information can be provided with in the following way:
Session service: for the stronger session service of real-time, can not shunt, perhaps shunt according to control signaling traffic stream and the professional son stream of business datum two parts;
Streaming media service: can shunt according to video traffic stream and audio service stream two parts, perhaps shunt according to basic layer service stream and the professional sub-stream of enhancement layer;
Interaction service: can and coordinate the professional son stream of (in line) object two parts and shunt typical application such as HTTP business according to the professional son stream of master (main objects) object;
Background class traffic: typical application such as Ftp business, because the homogeney (being that professional integral body has same QoS demand) of Ftp business, therefore, the Ftp Business Stream can be cut apart arbitrarily.
Step 430:CRRM 1 is according to the shunting advisory information that obtains, in conjunction with the network environment information generation corresponding service distributing strategy of Access Network 1 and Access Network 2.
For example, the business of user terminal 20 current request is a video traffic, the shunting advisory information indication that CRRM 1 obtains is divided into video sub-streams and audio sub-stream with the Business Stream of this video traffic, and this video sub-streams has different QoS demand (comprising delay requirement, rate requirement etc.) respectively with audio sub-stream; Then, CRRM1 searches corresponding suitable sex factor value according to video sub-streams and audio sub-stream QoS demand separately, promptly the network environment information in conjunction with Access Network 1 and Access Network 2 is that video sub-streams and audio sub-stream select optimal access network to transmit respectively, thereby realizes the shunting access control.
Step 440, CRRM 1 mail to user terminal 20 with the service distributing strategy that generates, and with indicating user terminal 20 Business Stream of its request are shunted.
In the present embodiment, user terminal 20 needed to set up network with CRRM 2 earlier and is connected before Business Stream is shunted, and CRRM 1 can be connected so that it sets up network with CRRM 2 with the relevant information informing user terminal 20 of CRRM 2 in service distributing strategy; With after CRRM2 sets up network and is connected, user terminal 20 is shunted the Business Stream of self request, and each professional sub-flow point that will obtain is not uploaded by CRRM 1 and CRRM 2.
Step 450:CRRM 1 mails to CRRM 2 with the service distributing strategy that generates.
Step 460:CRRM 2 carries out the service distributing strategy that CRRM 1 issue, and connects with user terminal 20, and receives professional son stream after the shunting that user terminal 20 uploads.
1 pair of user terminal of step 470:CRRM 20 carries out conventional admittance control, need not to indicate it that Business Stream is shunted.
Based on the foregoing description, consult shown in Figure 5, in step 430, when CRRM 1 need to determine indicating user terminal 20 that its Business Stream is shunted, CRRM 1 is according to the shunting advisory information of obtaining, and the detailed process that generates the corresponding service distributing strategy in conjunction with the network environment information of Access Network 1 and Access Network 2 is as follows:
Step 500:CRRM 1 obtains the network environment information of Access Network 1, and in the present embodiment, the network environment information of Access Network 1 comprises the suitable sex factor (hereinafter referred to as suitable sex factor 1) of Access Network 1 at least.
In the present embodiment, adapt to the factor and be used to represent the appropriateness of an access network for one type business, it specifically is defined as: j the appropriateness that access network is served for the s kind in the configuration of p kind, can represent by the mode of formula 1:
Wherein,
S
S, jBe used to represent the support of j access network for the service of s kind;
Q
P, s, jBe used to represent the suitability of j kind access network to the s kind service of p kind configuration, it can be set in advance according to practical experience by administrative staff;
δ is used to represent the offered load of whole access network;
Wherein, load condition can be measured by the CRRM in the access network, load generally adopts the normalization load to get final product as tolerance, for example: in the LTE network, with the ratio of the total number of the number of the subcarrier that used in the network and network sub-carriers as the current network load:
Above-mentioned S
S, j, Q
P, s, j, in these three parameters, S
S, jAnd Q
P, s, jValue be to set in advance in each CRRM by administrative staff at the network planning initial stage, and the computing formula of δ can be set in advance by the custodian, and regularly its value is upgraded according to default formula by the CRRM in the access network.
Illustrate:
Suppose to have three access networks, its sign is respectively: j
1, j
2, j
3
Each access network all has two kinds of selectable configuration modes, and its sign is respectively: p
1, p
2
And these three kinds of networks can be supported two types business, and its sign is respectively: S
1, S
2
So, if fit sex factor be:
, represent that then network is at configuration p
1Be S to type of service under the condition
1The support of business.
In above-mentioned three kinds of access networks, suppose that the access network of user terminal 20 acquiescences is network j
2, then three access networks calculate suitable sex factor separately respectively, and network j
1With j
3The result of calculation of self is passed to network j
2, network j
2The suitable sex factor of each access network that obtains can adopt the forms mode record, and is as shown in table 1, at the combination of every kind of j, p, s, all records a corresponding suitable sex factor value, therefore, and every kind of all corresponding one group of suitable sex factor value of access network:
Table 1
Above-mentioned table 1 need upgrade according to the cycle of setting, like this, and network j

3Network state.
On the other hand, can also comprise network load information, channel quality information or the like for your guidance in the network environment information, not repeat them here.
Step 510:CRRM2 obtains the network environment information of Access Network 2, and in the present embodiment, the network environment information of Access Network 2 comprises the suitable sex factor (hereinafter referred to as suitable sex factor 2) of Access Network 2 at least.
In like manner, the network environment information that CRRM 2 obtains also can comprise network load information, channel quality information or the like for your guidance, also repeats no more at this.
Step 520:CRRM 2 is sent to CRRM1 with the network environment information of Access Network 2.
Step 530; CRRM 1 obtains corresponding shunting advisory information at the traffic type information of user terminal 20 request (as, user's qos requirement).
In actual applications, CRRM 1 can obtain the shunting advisory information in policy library, perhaps, if administrative staff will shunt advisory information and set in advance in each CRRM, CRRM 1 also can obtain required shunting advisory information in this locality, and present embodiment is that example is introduced to obtain the shunting advisory information in policy library only.
On the other hand, in the above-described embodiments, step 500, step 510 and step 520 all can periodically be carried out, and do not have strict execution sequence, for example, step 500 and step 510 also can be carried out synchronously, perhaps first execution in step 510, step 520, execution in step 500 again, can reach desirable technique effect equally, do not repeat them here.
Step 540:CRRM 1 assesses according to the network state of suitable sex factor 1, suitable 2 pairs of Access Networks 1 of sex factor and Access Network 2, and generates the corresponding service distributing strategy in conjunction with the shunting advisory information that obtains.
In above-mentioned two embodiment, CRRM 1 also can obtain the network environment information of Access Network 1 and the network environment information that obtains Access Networks 2 from CRRM 2 in advance from this locality before the business request information that receives user terminal 20 transmissions, like this, after receiving service requesting information, CRRM 1 just can directly obtain the shunting advisory information in this locality or policy library, generate the corresponding service distributing strategy in conjunction with Access Network 1 and Access Network 2 network environment information separately, can reach desirable technique effect equally, not repeat them here.
On the other hand, because the network environment of each Access Network is constantly changing, therefore, the network environment information of the Access Network that the CRRM in each Access Network need self belong to according to the cycle acquisition of setting, and it is mail to other access network, like this, each CRRM just can in time obtain the network environment information of each access network, thereby control the access network state of whole distributed heterogeneous communication system, so that this user terminal 20 is shunted access control in conjunction with the QoS demand of user terminal 20 propositions.
Based on above-mentioned two embodiment, behind the service distributing strategy that user terminal 20 obtains finally to issue, Business Stream is divided into a plurality of professional son streams, and adds different labels, for example, in the present embodiment, Business Stream T is divided into two professional son streams, is respectively:
... with
..., the QoS demand of two professional son streams is respectively Q
T1With Q
T2, then, user terminal 20 connects with Access Network 1 and Access Network 2 respectively, and will cut apart two good sub-flow points of business and not transmit by Access Network 1 and Access Network 2.Under the network configuration of distributed heterogeneous communication system, if the service distributing strategy that issues indication will have a plurality of professional son streams by same access network transmission, then the CRRM in this access network transmits after above-mentioned a plurality of professional son streams are merged again, for example, a Business Stream is divided into three professional son streams by user terminal 20, is respectively: T
1, T
2With T
3, wherein, the service distributing strategy indication that CRRM1 issues: T
1 By Access Network 1 transmission, T
