Embodiment
Embodiment one
The present embodiment provides the user under a kind of base station direct connection framework changing method.The method of the present embodiment is specially adapted to can directly carry out in the base station direct connection framework of transfer of data between base station.Such as, as shown in Figure 2, Access Network comprises management control center and multiple base station, and each base station is connected with management control center.Management control center receives the service request of each base station, and issues connection signaling according to service request, makes to set up data put-through channel between base station and base station, to carry out the transmission of data or signaling between each base station.
In the following description of this enforcement, the data between each base station and the transmission of signaling are all that the data put-through channel by having set up between base station connects.The process that this data put-through channel is set up can be as follows.
For the network architecture shown in Fig. 2, its flow process setting up data put-through channel is specially:
Step 2011: management control center receive source base station report by transmit leg Client-initiated service request, service request comprises transmit leg user ID, service identification and recipient's user ID;
Step 2021: management control center, according to recipient's user ID, determines the target BS of recipient's user attaching;
Step 2031: management control center, according to source base station and target BS, determines the transmission path of business datum, transmission path comprise source base station, target BS and business datum from source base station to target BS process by way of base station;
Step 2041: management control center according to transmission path and service identification to source base station, to distribute with target BS by way of base station and be connected signaling;
Step 2051: source base station, by way of base station and target BS according to the transmission being connected signaling and service identification and carrying out business datum.
Carry out concrete example with the network architecture shown in Fig. 2 below to illustrate, for being how to set up data put-through channel between source base station and target BS.
Concerning source base station, after receiving connection establishment signaling, therefrom obtain the address by way of base station that this business datum will be sent to, and identify needs and data put-through channel should be set up by way of base station, therefore open the straight-through functional interface of oneself, such as I-X2 interface.Then, source base station leads directly to control message, with by way of base station to set up data put-through channel along transmission path to sending by way of base station by the straight-through functional interface of oneself.
For by way of base station, after receiving connection signaling, therefrom obtain target BS address, and identify need with target BS set up data put-through channel, therefore open the straight-through functional interface of oneself, such as I-X2 interface, after receiving the response that target BS returns, sets up by way of the data put-through channel between base station and target BS.Then, receive the business datum of source base station transmission by way of base station after, identify that this business datum identifies, thus learn according to connecting signaling the target BS address needing this business datum to send, the data put-through channel next by having set up sends this business datum to target BS.Especially, when comprising multiple subbase station by way of base station, after other each subbase station in transmission path except last subbase station receives and connects signaling, therefrom obtain the address needing the adjacent subbase station of next one business datum be sent to, therefore open the straight-through functional interface of self, such as I-X2 interface, after receiving the response that next adjacent subbase station returns, sets up the data put-through channel between self subbase station adjacent with the next one.Then after self receiving the business datum of an adjacent subbase station transmission, identify that this business datum identifies, thus learn according to connecting signaling which the adjacent subbase station needing this business datum to be sent to, the data put-through channel next by having set up sends business datum to the adjacent subbase station of the next one.For last the subbase station in transmission path, be also identical process, be just the address of target BS from connecting what obtain signaling, and set up data put-through channel with target BS.
For target BS, after receiving connection establishment signaling, therefrom obtain by way of base station address and transmission path, and identify needs and set up data put-through channel by way of base station, therefore open the straight-through functional interface of oneself, such as I-X2 interface.Then, the straight-through control message that target BS wait-receiving mode sends by way of base station, and after receiving the straight-through control message sent by way of base station, being receiveed the response to sending straight-through control by way of base station along transmission path by the straight-through functional interface of oneself, just establishing data put-through channel with target BS when receiving by way of base station after straight-through control that target BS returns is receiveed the response.
I-X2 interface in the present embodiment is an open interface, and its major function is the exchange realizing signaling between base station and business datum.From logical perspective, I-X2 interface is the point-to-point interface between base station.In the present embodiment, this I-X2 interface primary responsibility realizes source base station, Signalling exchange when leading directly to by way of base station and target BS, completes source base station, passes the carrying of data (i.e. business datum) transmit by way of the user face of base station and target BS.Fig. 3 A shows source base station, process by way of the Signalling exchange between base station and target BS from the chain of command protocol stack angle of I-X2 interface; The process that Fig. 3 B shows source base station from the user face protocol stack angle of I-X2 interface, exchanges by way of the business datum between base station and target BS.As shown in Figure 3A, the chain of command protocol stack of I-X2 interface mainly comprises: physical layer, data link layer, IP layer, SCTP layer and application layer.As shown in Figure 3 B, the user face protocol stack of I-X2 interface mainly comprises: physical layer, data link layer, IP layer, User Datagram Protoco (UDP) (UserDatagram Protocol; Referred to as: UDP) layer, general data transfer layer and business datum layer.
The above-mentioned mode setting up data put-through channel is only and illustrates, the present embodiment does not limit how setting up data put-through channel.Under the above-mentioned network architecture, the transfer of data that user carries out when carrying out the operation of base station switching all can have been come by data put-through channel.
It is to be noted, " handover source base station " below can be the base station that transmit leg user connects, and also can be the base station that recipient user connects, and corresponding " switching object base station " is consistent with handover source base station, can be above-mentioned source base station, also can be above-mentioned target BS.Specifically, when handover source base station and switching object base station are source base station, base station, business opposite end is exactly above-mentioned target BS, and when handover source base station and switching object base station are target BS, base station, business opposite end is exactly above-mentioned source base station.
As shown in Figure 4, be the schematic flow sheet according to the user's changing method under the base station direct connection framework of the present embodiment, comprise:
Step 401, when handover source base station recognize user need switching cell time, cell merge request is initiated in the switching object base station to correspondence.
Here handover source base station refers to the current base station connected of user.It is a variety of that handover source base station identification user needs the method for switching cell to have.Such as, handover source base station receives the measurement report of reporting of user, according to the signal power in measurement report and/or current geographic position information, judges whether user needs switching cell.When finding that the signal power of user is more weak, then this user very possible has moved position and has arrived in the signal cover of another one base station, namely stronger for its signal power of another one base station.Now, user collects the signal power of adjacent base station and forms measurement report, then user selects a signal power to be worth maximum base station as switching object base station from each measurement report, and the switching object Base Station Identification of this switching object base station is sent to handover source base station; Or user collects the signal power of adjacent base station and forms measurement report, and the measurement report of the intensity comprising the signal power of each base station that can be connected with this user is sent to handover source base station, selected to switch object base station according to measurement report by handover source base station, or by handover source base station, the measurement report of reporting of user is sent to management control center, selected to switch object base station according to measurement report by management control center.Certainly, the geographical location information of all right direct-detection user of handover source base station, or the geographical location information that reception user reports every predetermined period, judge whether user needs switching cell.It is a lot of that handover source base station judges whether user needs the method for switching cell to also have, and do not limit in the present embodiment to this.
Cell merge request can comprise phone number and the IMEI (International MobileEquipment Identity, International Mobile Equipment Identity code) of user, which user will set up wireless connections with to make switching object identification of base stations.
Step 402, handover source base station receives the cell merge response switching object base station and return, and is transmitted to user, with the wireless connections between indicating user release and handover source base station, and sets up and switches the wireless connections between object base station.
If handover source base station just illustrates that switching object base station has carried out corresponding preparation, is user and reserves resource to set up wireless connections with it after receiving and switching cell merge response that object base station returns.The response of this cell merge can comprise the identification number switching object base station.Cell merge response is sent to user by handover source base station, and user, after receiving cell merge response, discharges the wireless connections between handover source base station, and sets up and switch the connection between object base station.
Step 403, when handover source base station receive switch object base station return cell merge success response time, business opposite end Base Station Identification is sent to and switches object base station, maybe switching object Base Station Identification is sent to base station, business opposite end, to make switching object base station or business opposite end base station triggers perform the current data put-through channel Establishing process switched between object base station and base station, business opposite end, the two ends of current data put-through channel are respectively and switch object base station and base station, business opposite end.
Handover source base station receives the cell merge success response switching object base station and return, and namely illustrates that switching object base station sets up wireless connections with user.Now, switching object base station and base station, business opposite end can be indicated to set up current data put-through channel, to carry out the transmission of business datum.The two ends of current data put-through channel are respectively and switch object base station and base station, business opposite end, namely switch object base station and receive transmit leg user uploading data, and base station, business opposite end sends data to recipient user, or base station, business opposite end receives transmit leg user uploading data, and switching object base station sends data to recipient user.
What switch that object base station and base station, business opposite end set up described in the process of current data put-through channel and step 2011 ~ 2051 is consistent, does not repeat them here.
It needs to be noted, here the current data put-through channel set up between switching object base station and base station, business opposite end original data put-through channel that is very possible and that set up between handover source base station and base station, business opposite end has the part of repetition, such as switching object base station is a transfer base station in original data put-through channel, now, can select to re-establish the current data put-through channel switched between object base station and base station, business opposite end, also the transmission carrying out data according to original data put-through channel can be selected, but in any case, the scope that " foundation " that all belongs to the present embodiment comprises, because the current data put-through channel set up in the present embodiment is to switch object base station and base station, business opposite end for two ends.
According to the user's changing method under the base station direct connection framework of the present embodiment, make user when switching cell, sum operation is asked by what directly carry out toggle path between base station, the transmission path of business datum is changed in time, the normal transmission of business datum can not only be ensured, and need not forward through core net again due to request and the transmission of business datum, reduce the time that user carries out required for the switching of base station to a certain extent.
Embodiment two
The present embodiment does further supplementary notes to the user's changing method under the base station direct connection framework of embodiment one.
The present embodiment performs to the switching object base station in step 403 or business opposite end base station triggers the data put-through channel Establishing process switched between object base station and base station, business opposite end and is further explained explanation, other step is all consistent with embodiment one, does not repeat them here.
Switching object base station or business opposite end base station triggers perform the data put-through channel Establishing process switched between object base station and base station, business opposite end and specifically comprise:
Steps A: switch object base station or base station, business opposite end and send judgement information to management control center, judgement information comprises switching object Base Station Identification, business opposite end Base Station Identification and service identification.
Service identification in this step be certain user send some business datums mark, different business datums correspond to different service identifications.When the transmission of multiple business datum is carried out in base station simultaneously, the business datum that needs to which base station forwarding user are uploaded can be determined by this service identification in base station.After management control center receives judgement information, can handover source base station mark be obtained according to this service identification and switch object Base Station Identification.What can imagine is, due to when setting up original data put-through channel between handover source base station and base station, business opposite end, send connection signaling by management control center to set up, management control center has known the service identification corresponding with this data put-through channel, so management control center can by the corresponding handover source base station of service identification identification and base station, business opposite end.In judgement information, send business opposite end Base Station Identification, be to make management control center according to the protocol identification of making an appointment to being switch between object base station and base station, business opposite end to set up current data put-through channel simultaneously.Step B: when management control center to judge according to judgement information number of base stations that the first transmission path between handover source base station and base station, business opposite end comprises be greater than switch number of base stations that the second transmission path between object base station and base station, business opposite end comprises time, what switching object base station or base station, business opposite end receiving management control centre returned sets up instruction, and according to setting up instruction triggers current data put-through channel Establishing process, setting up instruction and comprising the second transmission path.
Switch object base station or base station, business opposite end receive represent need to set up current data put-through channel set up instruction time, just carry out the operation triggering current data put-through channel Establishing process.Setting up in instruction and comprise the second transmission path, can be that switching object base station or base station, business opposite end clearly need to set up current data put-through channel between which base station like this.This be due to, switch object base station or base station, business opposite end likely to receive simultaneously and multiplely set up signaling, when set up in signaling comprise transmission path time, switch object base station and can know the service identification that the current data put-through channel that next will set up is corresponding, and when receiving corresponding business datum, passing through set up current data put-through channel and transmitting.
It should be noted that, the original data put-through channel set up between handover source base station and base station, business opposite end may need through 0, one or more base stations, the path set up through these base stations according to sequencing is the first transmission path, the first transmission path with handover source base station and base station, business opposite end for two ends.Equally, switching the current data put-through channel set up between object base station and base station, business opposite end may need through 0, one or more base stations, and the path set up through these base stations according to sequencing is the second transmission path.When the number of base stations comprised in the first transmission path is greater than the number of base stations comprised in the second transmission path, just need to re-establish current data put-through channel.If there is part to have overlapping with original data put-through channel in current data put-through channel, original data put-through channel can be adopted.Such as, base station P and base station Q belongs to two base stations adjacent in the first transmission path and the second transmission path, the data put-through channel corresponding with service identification has been established between base station P with base station Q, so when setting up current data put-through channel, original data put-through channel between base station P and base station Q can be adopted.Before this, management control center can be selected whether to be connected signaling to base station P with base station Q transmission, when management control center is connected signaling to base station P and base station Q transmission, when base station P and base station Q recognizes and establishes the data put-through channel corresponding with this service identification, can select not respond this connection signaling; When manage control always new to base station P and base station Q do not send be connected signaling time, when base station P or base station Q receives the business datum corresponding with service identification, base station P is just sent to base station Q by original data put-through channel or is sent to base station P by original data put-through channel by base station Q.
In addition, also it is pointed out that if when the first transmission path is not more than the second transmission path, just can continue employing first transmission path.Be specially, base station, business opposite end receives the business datum that transmit leg user sends, and be sent to handover source base station by the data put-through channel corresponding with the first transmission path, recipient user is sent to by switching the switch data put-through channel set up between object base station again by handover source base station, or switch the business datum of object base station reception transmit leg user transmission and send to handover source base station by switching the switch data put-through channel set up between object base station and handover source base station, after handover source base station receives business datum, just be sent to base station, business opposite end by the data put-through channel corresponding with the first transmission path, recipient user is sent to again by base station, business opposite end.That is, the data put-through channel that the first transmission path is corresponding and switch data put-through channel are together as current data put-through channel.
Alternatively, the method for the present embodiment also comprises after stepb:
Step C, the data put-through channel between each base station that management control center triggers non-duplicate part in the first transmission path and the second transmission path discharges flow process.
When management control center is by contrast first transmission path and the second transmission path, if recognize in the first transmission path and the second transmission path and have non-duplicate part, data put-through channel release signaling can be sent in corresponding base station in non-duplicate part, this data put-through channel release signaling can comprise the adjacent base station mark in the first transmission path, knows to make corresponding base station the data put-through channel discharged between which base station.Release data put-through channel can be avoided taking Internet resources, further mitigates the burden of whole network.
Concrete example, when the first transmission path is followed successively by from source base station to target BS: base station R1, base station R2, base station R3, base station R4, second transmission path is followed successively by S1 from source base station to target BS, R3, during R4, management control center is by contrast first transmission path and the second transmission path, the part that can recognize repetition is R3 and R4, now, data put-through channel release signaling is sent to base station R1 and base station R2, when base station R1 and base station R2 receives data put-through channel release signaling, just send data put-through channel releasing request to next adjacent base station, when receiving the data put-through channel release response of replying next adjacent base station, just discharge the data put-through channel corresponding with service identification.Such as, base station R1 sends data put-through channel releasing request to base station R2, and base station R2 is to base station R1 return data put-through channel release response, and base station R1 discharges the data put-through channel between the R2 of base station.
Embodiment three
The present embodiment does further restriction to the user's changing method under the base station direct connection framework of above-described embodiment one and embodiment two.
In the present embodiment, to step 401 when handover source base station recognize user need switching cell time, the concrete operations that cell merge request is initiated in switching object base station to correspondence explain, and consistent all with above-described embodiment of other step, does not repeat them here.
Particularly, as follows:
Step 501, handover source base station send service request to management control center, service request comprises the measurement report that handover source base station mark, cell merge request mark, switching object Base Station Identification and/or user upload, to make management control center determine to switch object base station according to service request, and determine the 3rd transmission path according to the base station switching target knowledge.
Handover source base station recognizes user when needing switching cell, can by the interface between management control center to the request of management control center reporting service.This handover source base station can be the base station connected to the base station that transmit leg user connects or recipient user.
The connection establishment signaling that step 502, handover source base station receiving management control centre send, set up data put-through channel to make handover source base station and to switch object base station according to connection establishment signaling, connection establishment signaling comprises handover source base station address, switches object base station address and the 3rd transmission path.
After determining handover source base station and switching object base station, management control center is that handover source base station and switching object base station select a paths as the 3rd transmission path used when setting up data put-through channel from mulitpath according to default selection strategy.Wherein, default selection strategy can be carry out according to shortest path principle the strategy selected, also can be to carry out according to the lightest principle of path load the strategy etc. selected, does not limit in the present embodiment.
After determining handover source base station, switching object base station and the 3rd transmission path, management control center is respectively to handover source base station and switch object base station transmission connection establishment signaling, and handover source base station address, the 3rd transmission path that switches object base station address and selection are carried in connection establishment signaling, set up switch data put-through channel to make handover source base station and to switch object base station according to the information in connection establishment signaling.
Step 503, handover source base station send cell merge request by switch data put-through channel to switching object base station.
Set up data put-through channel between handover source base station and switching object base station after, handover source base station and the cell merge solicited message switched between object base station just can be transmitted by data put-through channel, and without the need to by handover source base station or switch object base station to send core net to center control nodes by backbone transport networks, then forwarded by center control nodes is unified.The present embodiment is particularly useful for high bandwidth business, such as the multimedia service such as video traffic, P2P business.
