In the description of instantiation below, with specifying how to carry out sub-clustering, to realize cellular network architecture of the present invention based on the network architecture shown in Fig. 2 A.
Embodiment one
Present embodiment one provides the cellular network architecture implementation method, and the method for present embodiment is used for the network architecture shown in Fig. 2 A is carried out sub-clustering.
It is pointed out that in the operation below that each base station is just transmitted to other base stations when receiving bunch test post, because the straight-through functional interface of each base station all opens, so can receive bunch test post that transmit at non-interim bunch of headgroup station.
Shown in Fig. 3 A, the schematic flow sheet for according to the implementation method of the cellular network architecture of present embodiment comprises:
Step 301, bunch test post is sent to non-interim bunch of headgroup station in interim bunch of headgroup station, and receives bunch test response that returns.The non-interim bunch of headgroup station here is the base station except interim bunch of headgroup station.
Interim bunch of headgroup station is the interim bunch headgroup station of confirming, number can be one or more, and it temporarily has bunch function at headgroup station, is used for base station in definite bunch.In the concrete operations; When just determining each interim bunch of headgroup station and produce; Each interim bunch of headgroup station just will report management control center to self information; Management control center receives these information and sets up interim bunch of headgroup station tabulation according to these information, should interim bunch of headgroup station tabulation send to each interim bunch of headgroup station and other non-interim bunch of headgroup stations then.Therefore; Because other interim bunch of headgroup station known at each interim bunch of headgroup station in advance; Do not send when sending bunch test post to other interim bunch of headgroup station; Each base station can learn that which base station is interim bunch of headgroup station through the message that management control center sends; Which base station is non-interim bunch of headgroup station, can also judge that which base station is non-interim bunch of headgroup station through alternate manner certainly, and whether how present embodiment obtains other base station to interim bunch of headgroup station is that the mode at interim bunch of headgroup station is not done qualification.Interim bunch of all headgroup stations and non-interim bunch of headgroup station are all by same management control center management.In practical operation; Interim bunch of headgroup station can be confirmed through a variety of modes; For example from all base stations, select one or more base stations at random as interim bunch of headgroup station; Perhaps carry out after base station area divides according to the geographical position of each base station, select in each base station area one near the base station of regional center as interim bunch of headgroup station, for example dividing into same base station area near a plurality of base stations of same longitude or latitude.Present embodiment is not done qualification to definite mode at interim bunch of headgroup station.
Bunch test post in the present embodiment be used for confirming can with this interim bunch of headgroup station with bunch the base station.This bunch test post can comprise the ID (Identity, identification number) and/or the positional information at this interim bunch of headgroup station, it is pointed out that in the whole network architecture ID of each base station is unique.Bunch test response can comprise Base Station Identification and the positional information of returning this bunch test corresponding base station.
In this step, interim bunch of headgroup station sent bunch test post to non-interim bunch of headgroup station and can be sent to non-interim bunch of headgroup station through straight-through functional interface.
Step 302 when interim bunch of headgroup station identified corresponding base station and be positioned at bunch scope according to bunch test response, is regarded as interim member base station with the base station of correspondence.
Here judge whether the base station is positioned at bunch scope and specifically can judges according to the position of the base station of returning bunch test response.When the position of base station is in the position threshold scope that is provided with in advance, just can confirm that this base station is positioned at a bunch scope, and this base station is regarded as interim member base station that the position threshold scope here can set up on their own according to actual needs.In addition, interim bunch of headgroup station can also judge whether the base station is positioned at a bunch scope according to information such as the id number in bunch test response, regions, in the present embodiment to how judging that the mode whether base station is positioned at bunch scope do not do qualification.
Step 303, interim bunch of headgroup station are sent to interim member base station and bunch are joined request, and receive return bunch add response the time interim member base station confirmed as the fixed member base station.
When interim bunch of headgroup station recognizes interim member base station, will send to interim member base station and bunch join request.This bunch the join request ID that can comprise interim base station, bunch number, geographical location information or the like.Bunch adding response can comprise by the interim member base station load state of interim member's base station feedback, interface resource etc.Bunch number can be confirmed according to self ID number or geographical location information by interim bunch of headgroup station, to guarantee the uniqueness of bunch number, in the present embodiment the concrete mode of confirming bunch number do not done qualification.
Like this, when non-interim bunch of headgroup station receives bunch test post, return a bunch test response; When non-interim bunch of headgroup station receives one or more bunches when joining request, joining request to return to one bunch bunch adds response, joins request to other bunches and returns a bunch refusal response.
When interim member base station receives a plurality of bunches when joining request simultaneously, can judge according to bunch information that joins request to add in which bunch, perhaps add one of them bunch at random, in the present embodiment adding mode is not done qualification.
Alternatively, bunch refusal information can also be sent to non-interim member base station in interim bunch of headgroup station, accepts bunch joining request of other to inform these non-interim member base stations.
Step 304, interim bunch of headgroup station selected fixed tuft headgroup station according to the base station information of this base station with the base station information that each fixed member base station reports.
Before selecting fixed tuft headgroup station, interim bunch of headgroup station can be resolved from bunch adding response of returning and obtained the base station information of fixed member base station.Then, fixed tuft headgroup station can be selected according to load information, interface resource information or positional information that this base station and each fixed member base station report in interim bunch of headgroup station.For example that load is minimum base station is as fixed tuft headgroup station; Perhaps that interface resource is maximum base stations is as fixed tuft headgroup station; Perhaps will be near the base station at bunch center, base station as fixed tuft headgroup station; If the minimum base station of load does not have only one, just from the minimum base station of these a plurality of loads, select one at random as fixed tuft headgroup station; Equally, if the maximum base station of interface resource does not have only one, just from the maximum base station of these a plurality of interface resources, select one as fixed tuft headgroup station; Equally, if near not having only one in the base station at bunch center, base station, just from a plurality of near selecting one the base station at bunch center, base station at random as fixed tuft headgroup station.Can also take all factors into consideration to confirm fixed tuft headgroup station load information, interface resource information and positional information.In the present embodiment to how according to bunch in all members' base station information select fixed tuft headgroup station not do qualification, can be any in according to actual needs.
Step 305, notice fixed tuft headgroup station, interim bunch of headgroup station is so that the transfer of data between the base station of fixed tuft headgroup station in handling bunch.
After selecting fixed tuft headgroup station, just carry out bunch operation of intra-cluster headgroup station change.It is fixed tuft headgroup station for notice fixed tuft headgroup station, interim bunch of headgroup station, and this notice can be to send a notification message to fixed tuft headgroup station.ID, positional information, loading condition and port information of all members or the like in can comprising in the notification message bunch.What should be thought of is that this notification message is also sent to management control center in interim bunch of headgroup station, so that management control center obtains the information at each fixed tuft headgroup station, and the data of in follow-up transmission, each fixed tuft headgroup station being sent are handled.Fixed tuft headgroup station can know that just oneself is bunch headgroup station in this bunch after receiving this notice; Transmission with the business datum between all base stations in subsequent treatment bunch; And the control of receiving management control centre is carried out the transmission of business datum with other bunch headgroup station.Transfer of data between the base station in for example, handle bunch at fixed tuft headgroup station can comprise: straight-through functional interface is set up with each fixed member base station in fixed tuft headgroup station, and the routing table of interior each the fixed member base station of bunch scope of maintenance.
According to the cellular network architecture implementation method of present embodiment, through confirming to carry out sub-clustering through interim bunch of headgroup station again in interim bunch of headgroup station earlier; In each bunch, select fixed tuft headgroup station at last; So just formed the cellular network architecture of sub-clustering, handled the exchanges data of the base station in its bunch, handled the exchanges data between fixed tuft headgroup station by management control center again through each fixed tuft headgroup station; Promptly avoided a plurality of base stations to send business datum to core net simultaneously; Business datum can be transmitted in Access Network, has alleviated the burden of center control nodes and backbone transport networks, has also alleviated the burden of management control center simultaneously.The mode at the selection bunch headgroup station through present embodiment guarantees the stability of bunch headgroup station interface as far as possible with the framework cellular network.
What can expect is; Before each base station does not form base station bunch as yet; In order to make each base station can receive bunch test post and bunch to join request; So that with each base station be divided into different bunches with the fixed tuft headgroup station of selecting in each base station bunch, management control center just can send the instruction of opening all straight-through functional interfaces between the base station to each base station.After a base station bunch division is accomplished; Management control center is according to the result of sub-clustering; Close with in the cluster except the logic function of the straight-through functional interface of other base station at fixed tuft headgroup station and each base station in other bunch; The logic function here refers to, no longer with other bunch in each base station directly communicate.And each fixed tuft headgroup station is except can directly communicating with each the member base station in this bunch, and can also stand erectly to connect with other each fixed tuft headgroup communicates.
