In the following description of the present embodiment, the transmission of the data between each base station, message and signaling is 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 A ~ 2D, its flow process setting up data put-through channel is specially:

Step 2011: management control center receives the service request from source terminal that source base station reports, service request comprises source terminal mark, service identification and target terminal mark;

Step 2021: management control center identifies according to target terminal, determines the target BS that target terminal belongs to;

Step 2031: management control center judges whether source base station and target BS belong to identical cluster head base station, when management control center judges that source base station and target BS belong to different cluster head base stations, determine that service transmission path is source base station, cluster head base station, source, transfer cluster head base station, target cluster head base station and target BS, wherein, management control center is connected with one or more cluster head base station, and each cluster head base station is connected with one or more subbase station;

Step 2041: management control center issues respectively according to the base station that transmission path relates in transmission path and connects signaling and service identification;

Step 2051: receive the base station connecting signaling, according to the direct channel connected between signaling foundation with the adjacent base station in transmission path, and according to service identification service data transmission in direct channel.

Be described for the structure shown in Fig. 2 D below, its transfer cluster head base station is 1 cluster head base station.

Concerning source base station, after receiving connection signaling, therefrom obtain the address of the cluster head base station, source that this business datum will be sent to, and identify need with this cluster head base station, source set up data put-through channel, therefore open the straight-through functional interface of oneself, such as I-X2 interface, and send the request of setting up data put-through channel to this cluster head base station, source, after receiving the response that this cluster head base station, source returns, set up the data put-through channel between source base station and this cluster head base station, source.Then, source base station is when receiving business datum, by identification services Data Identification, thus learn according to connecting signaling the cluster head base station, source needing this business datum to be sent to, the data put-through channel next by having set up sends this business datum to cluster head base station, source.

For cluster head base station, source, after receiving connection signaling, the address of transfer cluster head base station therefrom obtaining source base station address and this business datum will be sent to, and identify needs and set up data put-through channel with this source base station and transfer cluster head base station respectively, therefore open the straight-through functional interface of oneself, such as I-X2 interface.After source cluster head base station waits receives the straight-through control message of source base station transmission, send straight-through control by the straight-through functional interface of oneself along transmission path to source base station to receive the response, just data put-through channel is established with cluster head base station, source when source base station receives after straight-through control that cluster head base station, source returns is receiveed the response, cluster head base station, source sends the request of setting up data put-through channel to transfer cluster head base station simultaneously, after receiving the response that this transfer cluster head base station returns, set up the data put-through channel between origin cluster head base station and this transfer cluster head base station.Then, cluster head base station, source is when receiving business datum, by identification services Data Identification, thus learn according to connecting signaling the transfer cluster head base station needing this business datum to be sent to, the data put-through channel next by having set up sends this business datum to transfer cluster head base station.

For transfer cluster head base station, after receiving connection signaling, the address of target cluster head base station therefrom obtaining source cluster head base station address and this business datum will be sent to, and identify needs and set up data put-through channel with cluster head base station, source and this target cluster head base station respectively, therefore open the straight-through functional interface of oneself, such as I-X2 interface.After transfer cluster head base station waits receives the straight-through control message of cluster head base station, source transmission, send straight-through control by the straight-through functional interface of oneself along transmission path to cluster head base station, source to receive the response, just data put-through channel is established with transfer cluster head base station when cluster head base station, source receives after straight-through control that transfer cluster head base station returns is receiveed the response, transfer cluster head base station sends the request of setting up data put-through channel to target cluster head base station simultaneously, after receiving the response that this target cluster head base station returns, set up the data put-through channel between source base station and this target cluster head base station.Then, transfer cluster head base station is when receiving business datum, by identification services Data Identification, thus learn according to connecting signaling the target cluster head base station needing this business datum to be sent to, the data put-through channel next by having set up sends this business datum to target cluster head base station.

For target cluster head base station, connecting after signaling when receiving, therefrom obtaining transfer cluster head base station address and target BS address, and identify needs and set up data put-through channel with transfer cluster head base station and target BS respectively, therefore open the straight-through functional interface of oneself, such as I-X2 interface.After target cluster head base station waits receives the straight-through control message of transfer cluster head base station transmission, send straight-through control by the straight-through functional interface of oneself along transmission path to transfer cluster head base station to receive the response, just data put-through channel is established with target cluster head base station when transfer cluster head base station receives after straight-through control that target cluster head base station returns is receiveed the response, target cluster head base station sends the request of setting up data put-through channel to target BS simultaneously, after receiving the response that target BS returns, set up the data put-through channel between target cluster head base station and target BS.Then, after target cluster head base station receives the business datum of transfer cluster head base station transmission, 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.

For target BS, connecting after signaling when receiving, therefrom obtaining target cluster head base station address, and identify and need to set up data put-through channel with target cluster head 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 target cluster head base station sends, and after the straight-through control message receiving the transmission of target cluster head base station, send straight-through control by oneself straight-through functional interface along transmission path to target cluster head base station to receive the response, just establish data put-through channel with target BS when target cluster head base station receives after straight-through control that target BS returns is receiveed the response.

The I-X2 interface of various embodiments of the present invention is open interfaces, 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 Signalling exchange during each base station direct connection, and the user face completing each base station passes the carrying transmission of data (i.e. business datum).Fig. 3 A shows the process of the Signalling exchange between source base station and target BS from the chain of command protocol stack angle of I-X2 interface; Fig. 3 B shows the process of the business datum exchange between source base station and target BS from the user face protocol stack angle of I-X2 interface.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) (User Datagram 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.It should be noted that, in the above-mentioned network architecture, store the mark of all base stations belonging to this cluster head base station in each cluster head base station, namely each cluster head base station is for managing all base stations in same cluster head.Each cluster head base station also has the ability being similar to management control center, namely set up that it manages bunch in each base station between data put-through channel, the burden of management control center can be alleviated like this, method for building up is similar to described above, is namely issued by cluster head base station and connects signaling and service identification.Data put-through channel between each cluster head base station still needs management control center to set up.

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.Following " handover source base station mark " and " switching object Base Station Identification " is special mark, except the mark comprising handover source base station and switch object base station itself, specific character or letter can also be added to make each base station or this base station of management control center identification for handover source base station or switching object 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, and then user selects a signal power to be worth maximum base station as switching object base station from each measurement report, and by the mark of this switching object base station, namely switch object Base Station Identification, send 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 has needed 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 Mobile Equipment Identity of user, International Mobile Equipment Identity code), which user will set up wireless connections with to make switching object identification of base stations.

This step specifically comprises:

Step 401a, when handover source base station recognize user need switching cell time, the handover source cluster head base station to handover source base station ownership sends and switches object Base Station Identification, judges whether switching object base station belongs to handover source cluster head base station to make handover source cluster head base station.

Owing to store the mark at all subbase stations that it manages in each cluster head base station, therefore, cluster head base station can judge according to received switching object Base Station Identification whether switch object base station belongs to this cluster head base station.Specific character can also be added to switching object Base Station Identification, when receiving switch object Base Station Identification to make cluster head base station, learn it is to carry out judgement operation.Have a lot in concrete mode prior art, do not repeated them here.

Step 401b, when judged result belongs to handover source cluster head base station for switching object base station, handover source base station sends cell merge request directly to switching object base station.

Particularly, handover source base station and the data put-through channel of how setting up switched between object base station can the process described by step 2011 ~ 2051 be set up for sending cell merge request, directly can be issued by handover source cluster head base station and connect signaling with the data put-through channel setting up handover source base station and switch between object base station, also can issue connection signaling by management control center." directly sending " in this step means that handover source base station does not need through any cluster head base station to the cell merge request switching the transmission of object base station.

Step 401c, when judged result does not belong to handover source cluster head base station for switching object base station, handover source base station sends cell merge request by handover source cluster head base station to switching object base station.

This step is specifically as follows, when handover source cluster head base station judges that switching object base station does not belong to this cluster head base station, inquiry request can be sent to management control center, inquiry request comprises service identification, switches object Base Station Identification and handover source cluster head Base Station Identification, judge according to each Base Station Identification prestored the switching object cluster head Base Station Identification that this switching object base station belongs to by management control center, and this switching object base station cluster head mark is returned to handover source cluster head base station, or after sending inquiry request to management control center, this inquiry request is forwarded to the cluster head base station that this handover source cluster head base station is adjacent by management control center, when adjacent cluster head base station is determined when as switching object cluster head base station, when namely determining that this switching object base station belongs to this cluster head base station, inquiry response is returned to management control center, or return inquiry response when establishing handover source cluster head base station and switch the data put-through channel between object cluster head base station directly to handover source cluster head base station, inquiry response comprises switching object cluster head Base Station Identification and service identification, know to make handover source cluster head base station which cluster head base station switches object base station belongs to.

Step 402, handover source base station receive switch that object base station returns cell merge response, and be transmitted to user, with the wireless connections between indicating user release with handover source base station, and set up and the wireless connections switched 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 is after receiving cell merge response, and the wireless connections between release and handover source base station, then, user sets up and switches the connection between object base station.

Step 403, when handover source base station receive switch object base station return cell merge success response time, send first to switching object cluster head base station and judge information, judge whether base station, business opposite end belongs to make switching object cluster head base station according to the business opposite end Base Station Identification that first judges in information and switch object cluster head base station, and the current data put-through channel Establishing process switched between object base station and base station, business opposite end is triggered according to judged result, 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, first can be sent to switching object cluster head base station and judge information, this the first judgement information comprises business opposite end Base Station Identification and switches object Base Station Identification, certainly service identification can also be comprised, this service identification may reside in the first judgement information, also can be sent to switching object base station by handover source base station in subsequent process, specifically can set according to actual needs.After switching object cluster head base station receives the first judgement information, judge that information judges whether base station, business opposite end belongs in this cluster head base station according to first.And the Establishing process of subsequent triggers current data put-through channel is carried out according to judged result.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.

Switch object base station and base station, business opposite end to set up source base station and target BS in the process of current data put-through channel and embodiment one to set up the flow process of data put-through channel consistent, do 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 is very possible and switch the part that the original data put-through channel set up between object base station and base station, business opposite end has 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 is described further the user's changing method under the base station direct connection framework of embodiment one.

According to the business opposite end Base Station Identification that first judges in information, the present embodiment only judges whether base station, business opposite end belongs to the switching object cluster head base station in step 403 and switches object cluster head base station, and be described further according to the current data put-through channel Establishing process that judged result triggers between switching object base station and base station, business opposite end, consistent all with embodiment one of other step, does not repeat them here.

Particularly, switch object cluster head base station and judge whether base station, business opposite end belongs to switching object cluster head base station according to the business opposite end Base Station Identification that first judges in information, and comprise according to the current data put-through channel Establishing process that judged result triggers between switching object base station and base station, business opposite end:

Step 4031a, switches object cluster head base station reception first and judges information, and judge whether base station, business opposite end belongs to this cluster head base station according to the first business opposite end Base Station Identification judged in information.

Except comprising business opposite end Base Station Identification and switching except object Base Station Identification in first judgement information, service identification and handover source base station mark can also be comprised.

Step 4031b, when judged result is for being, switches object cluster head base station and directly setting up the current data put-through channel switched between object base station and base station, business opposite end.

Owing to carrying business opposite end Base Station Identification in the first judgement information and switching object Base Station Identification, therefore switch the current data put-through channel directly can set up base station, business opposite end and switch between object base station in object cluster head base station.The concrete Establishing process of this current data put-through channel can be consistent with embodiment one, and difference no longer issues connection signaling by management control center, but issue connection signaling by switching object cluster head base station, can alleviate the burden of management control center like this.

Particularly, at 4031b when judged result is for after being, namely after switching object cluster head base station judges that base station, business opposite end belongs to this cluster head base station, and before switching the current data put-through channel directly set up between switching object base station and base station, business opposite end object cluster head base station, also comprise:

Switch object cluster head base station and identify whether handover source base station belongs to switching object cluster head base station according to the handover source base station mark that first judges in information;

When switching object cluster head identification of base stations and belonging to this cluster head base station to handover source base station, switch the first transmission path between object cluster head base station acquisition handover source base station and base station, business opposite end.

Now, in step 4031b switching object cluster head base station directly set up the current data put-through channel step switched between object base station and base station, business opposite end and specifically comprise:

Step x1: switching object cluster head base station judges whether the number of base stations that the first transmission path comprises is greater than the number of base stations switching the second transmission path between object base station and base station, business opposite end and comprise;

Step y1: when judged result is for being, switches object cluster head base station and performs the current data put-through channel directly set up and switch between object base station and base station, business opposite end according to the second transmission path.

Work as handover source base station, when switching object base station and base station, business opposite end all belong to and switch object cluster head base station, namely when handover source cluster head base station and switching object cluster head base station are same cluster head base station, switch the first transmission path between object cluster head base station acquisition handover source base station and base station, business opposite end, obtain manner can be first judge whether the data put-through channel between handover source base station and base station, business opposite end is set up by this switching object cluster head base station, if judged result is yes, then from stored record, obtain the first transmission path, if judged result is no, the message of inquiry first transmission path can be sent to management control center, the first transmission path that receiving management control centre sends, can also be that handover source base station just can obtain the first transmission path according to the handover source base station mark in the first judgement information and business opposite end Base Station Identification, this be due to, be not random when setting up transmission path, but take certain strategy, the such as the lightest principle of load, the minimum principle in transfer base station, therefore, switch object cluster head base station and from the routing table of self, directly can obtain the first transmission path according to handover source base station mark and business opposite end Base Station Identification.In addition, switch object base station according to the routing table of self, obtain the second transmission path switched between object base station and base station, business opposite end, and then contrast the first transmission path and the second transmission path.

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 subbase stations, and the path set up through these subbase stations according to sequencing is the first transmission path.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 subbase 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 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, switch object cluster head base station can select whether to be connected signaling to base station P with base station Q transmission, when switching object cluster head base station and being 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 switch object cluster head base station 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 step y1:

Data put-through channel between each base station switching non-duplicate part in object cluster head base station triggers first transmission path and the second transmission path discharges flow process.
