Below the above-mentioned data transmission method that further embodiment of the invention is provided is described in detail.

In specific implementation process, in comprising the general wireless network of IAD, setting up the local Business Stream of transmitting can be finished by IAD, in the flattening network and since the base station integrated the function of IAD and general base station, therefore, local foundation of transmitting Business Stream can be finished by the base station, below be that example describes with the IAD, in the flattening network, the function of following IAD is realized by the base station.

In specific implementation process, foundation is used for the local Business Stream of transmitting and is initiated by source UE, source UE is before sending data to purpose UE, at first send Business Stream and set up request message to network side, wherein, this Business Stream is set up the user profile of carrying active UE in the request message and the address information of purpose UE.In specific implementation process, the user profile of source UE comprises: the protocol type that the IP address of source UE, the port numbers of source UE, source UE adopt, the address information of purpose UE comprises: the IP address of purpose UE or the MAC Address of purpose UE.

IAD is after the above-mentioned Business Stream that receives this source UE transmission is set up request message, from this request message, parse the address information of purpose UE, if this purpose UE and source UE are the UE of same base management, then IAD initiates to set up the above-mentioned local Business Stream of transmitting.In addition, also can set up the local Business Stream of transmitting between the UE that different base station is managed, can set in advance in specific implementation process needs the UE of the local forwarding of foundation Business Stream right, and with these UE to being kept at IAD (in the flattening network, be kept at the base station), IAD is after the Business Stream that receives source UE transmission is set up request message, can judge between source UE and the purpose UE whether be that needs are set up the local Business Stream of transmitting according to the information that preserve this locality, if then IAD is initiated the local flow process of setting up of transmitting Business Stream.

In the process of setting up the local Business Stream of transmitting, the attribute information of this Business Stream is preserved in the base station, and is this traffic flow assignment empty link address.Particularly, the attribute information of this Business Stream that preserve the base station is the grader attribute of this Business Stream, and this grader attribute includes but not limited to one of following parameter: protocol type, the IP address of purpose UE or the MAC Address of purpose UE that the port numbers of the IP of source UE, source UE, source UE adopt.

In specific implementation process, the above-mentioned Business Stream that is used for local forwarding that IAD is set up can comprise three kinds of situations:

One, Business Stream be originate in the user to, end at the uplink service stream of base station and originate in the base station, end at the right downstream service flow of user, be i.e. UE → base station, source and base station → purpose UE;

Two, Business Stream is to originate in source UE, end at the one-way traffic flow end to end of opposite end UE, i.e. UE → base station, source → purpose UE via the base station;

Three, Business Stream is source UE via the stream of the two-way services end to end between base station and the opposite end UE, promptly source UE ← → base station ← → opposite end UE.

Corresponding to different Business Streams the different implementations of setting up is arranged, below respectively these three kinds of situations are described.

1. Business Stream is the uplink service stream of UE → base station, source and the downstream service flow of base station → purpose UE

In this case, Business Stream is set up process and can be divided into source UE and work two processes of being exhaled with purpose UE of exhaling.

Wherein, Fig. 2 exhales the flow chart of setting up the local Business Stream of transmitting in the process for source UE rises, as shown in Figure 2, mainly comprise the steps:

Step S201: source UE initiates Business Stream and sets up request message, wherein, carry the port numbers of IP, the source UE of active UE, protocol type, the IP address of purpose UE or the MAC Address of purpose UE etc. that source UE adopts in this message, this request message is transmitted to IAD via the base station;

Step S203: IAD is set up request message to the Business Stream among the step S201 and is responded, and the feedback Business Stream is set up response message, and this message is transmitted to source UE via the base station, sets up the uplink service stream between source UE and the base station.The base station is the corresponding ascending idle port link address of this uplink service flow distribution when transmitting this response message;

In specific implementation process, it can also be in step S201 that uplink service flows corresponding ascending idle port link address, when the base station receives request message, be the corresponding ascending idle port link address of this uplink service flow distribution just, this address be carried at be transmitted to IAD in the request message then;

Step S205: source user is responded Business Stream and is set up acknowledge message, wherein, carry the complete grader attribute of this uplink service stream in this acknowledge message, this grader attribute comprises: protocol type, the IP address of purpose UE or the MAC of purpose UE etc. that the port numbers of the IP of source UE, source UE, source UE adopt;

Step S207: the grader attribute of uplink service stream among the step S205 is preserved in the base station, and Business Stream is set up acknowledge message is transmitted to IAD.

After having set up above-mentioned uplink service stream, if there is existing downstream service flow between base station and the purpose UE, IAD can determine whether to select for use this downstream service flow to transmit the data that source UE sends, if select to use existing downstream service flow, IAD or base station can directly be associated above-mentioned uplink service stream with having downstream service flow now, and set up the mapping relations between the corresponding empty link address of the uplink service stream empty link address corresponding with this existing downstream service flow.

If IAD is not selected existing downstream service flow, or there is not existing downstream service flow between base station and the purpose UE, then IAD need be set up the downstream service flow between base station and the purpose UE, be that purpose UE is exhaled, Fig. 3 is set up the local Business Stream of transmitting for purpose UE exhales in the process flow chart, as shown in Figure 3, this process mainly comprises the steps:

Step S301: IAD is initiated Business Stream and is set up request message, be transmitted to purpose UE via the base station, the parameter that carries in this request message include but not limited to following one of at least or its combination in any: protocol type, the IP address of purpose UE or the information such as MAC Address of purpose UE that the port numbers of the IP of source UE, source UE, source UE adopt.In addition, the base station is this traffic flow assignment corresponding downstream empty link address when transmitting described request message;

In specific implementation process, the base station also can be carried out among the step S303 below for this traffic flow assignment corresponding downstream empty link address, when receiving response message, for this traffic flow assignment corresponding downstream empty link address, and this empty link address is carried at is transmitted to IAD in the response message.

Step S303: purpose UE sets up request message to above-mentioned Business Stream and responds, and replys Business Stream and sets up response message, and be transmitted to IAD via the base station;

Step S305: IAD is set up response message to the Business Stream among the step S303 and is confirmed, the feedback Business Stream is set up acknowledge message, carry the complete grader attribute of this Business Stream in this acknowledge message, this grader attribute comprises: protocol type, the IP address of purpose UE or the MAC Address of purpose UE etc. that the port numbers of the IP of source UE, source UE, source UE adopt;

Step S307: the base station is preserved among the step S305 Business Stream and is set up the grader attribute of the Business Stream that carries in the acknowledge message, and transmits this acknowledge message and send to purpose UE.

By setting up the Business Stream of source UE and purpose UE, the grader attribute of source UE can be preserved in IAD or base station, simultaneously, if this downstream service flow is special-purpose Business Stream, also can preserve the grader attribute of purpose UE; By accurate coupling, can determine the mapping relations between being connected of eating dishes without rice or wine of source UE and purpose UE to the grader of source UE and purpose UE.

If preserve the information of the UE of its management in the base station, then the address of the source UE between uplink service stream and the downstream service flow and the address of purpose UE can be passed through to compare in the base station, can judge whether this user is to being two UE of its management, if, then with two Business Stream associations, and set up ascending idle port and connect the mapping relations that are connected with downlink space interface; If do not preserve the information of the UE of its management in the base station, and the information of preserving the UE of BTS management in the IAD, then by UE address, source and purpose UE address between IAD comparison uplink service stream and the downstream service flow, if determine that this user is to two UE for the same base management, then, connect the mapping relations that are connected with downlink space interface thereby set up ascending idle port at the place, base station with the related information informing base station of Business Stream.

When source UE sends upstream data to purpose UE, source UE sends to the base station with data on ascending idle port connects, the base station is resolved to after the ascending idle port connection of data, can obtain corresponding downstream and eat dishes without rice or wine to connect, and data directly be carried out this locality transmit on this downlink space interface connects.

In specific implementation process, before purpose UE was exhaled, if this purpose UE not in network, then needs earlier purpose UE to be initiated paging, the paging flow process was similar to paging flow process of the prior art, does not repeat them here.

In specific implementation process, if purpose UE need send data to source UE, then need to set up uplink service stream between purpose UE and the base station and the downstream service flow between base station and the source UE, and set up that corresponding ascending idle port connects and the mapping relations of downlink space interface between connecting.

2. Business Stream is UE → base station, source → purpose UE

Fig. 4 be under this situation in, the flow chart set up of one-way traffic flow end to end, as shown in Figure 4, one-way traffic flow is set up and mainly be may further comprise the steps end to end:

Step S401: source UE initiates Business Stream and sets up request message, wherein, carry the port numbers of IP, the source UE of active UE, protocol type, the IP address of purpose UE or the MAC Address of purpose UE etc. that source UE adopts in this request message, this request message is transmitted to IAD via the base station;

Step S403: IAD receives the Business Stream of step S401 and sets up after the request message, obtains the address of purpose UE from this request message; If purpose UE and source UE are the UE of same base management, IAD is then initiated Business Stream to source UE, purpose UE, base station simultaneously and is set up request message, and request is set up and started from source UE, arrives the one-way traffic flow of purpose UE via the base station;

Step S405: the Business Stream that transmit among the step S403 base station is set up request message, and is eated dishes without rice or wine to connect for this traffic flow assignment by the base station; Corresponding to Business Stream, this is eated dishes without rice or wine to be connected to and originates in source UE, arrives the unidirectional empty link address of purpose UE via the base station;

Equally, the corresponding unidirectional empty link address of this one-way traffic flow can also be in step S401 or step S403, when the base station receives traffic request message, be the corresponding unidirectional empty link address of this one way traffic flow distribution, this empty link address be carried at be transmitted to IAD or purpose UE in the request message then;

Step S407: source UE, purpose UE, the Business Stream of base station in response in step S405 are set up request message, and the feedback Business Stream is set up response message, and the base station is transmitted to IAD with this response message;

Step S409: the Business Stream that IAD receives among the step S407 is set up after the response message, and the feedback Business Stream is set up acknowledge message, and is transmitted to source UE, purpose UE via the base station.

When source UE sends upstream data to purpose UE, data map is sent to the base station on empty link address, the base station is resolved to after the connection of eating dishes without rice or wine of data, and directly this locality is transmitted to purpose UE.

In specific implementation process, when IAD judges that purpose UE is not in network, need earlier purpose UE to be initiated paging, concrete paging flow process is similar to prior art, does not repeat them here.

In specific implementation process, if purpose UE need send data to source UE, then should rebulid one and originate in purpose UE according to above-mentioned flow process, via the base station, end at the one-way traffic flow of source UE.

Business Stream be source UE ← → base station ← → opposite end UE

In this case, two-way services stream is set up process and situation two is basic identical end to end, and unique difference is: IAD is that the Business Stream that source UE and purpose UE set up is the two-way teleservice stream via the base station; Correspondingly, the base station connects for two-way the eating dishes without rice or wine of eating dishes without rice or wine to be connected between source UE and the purpose UE via the base station of this traffic flow assignment.

In this case, when source UE sends upstream data to the purpose user, data are sent to the base station above-mentioned eating dishes without rice or wine in the connection, the base station is resolved to after the connection of eating dishes without rice or wine of data, and directly this locality is transmitted to purpose UE; In like manner, when purpose UE sends upstream data to source UE, equally data are being eated dishes without rice or wine to send to the base station in the connection accordingly, the base station is resolved to after the connection of eating dishes without rice or wine of data, and directly this locality is transmitted to source UE.

Equally, in this case, when IAD judged that purpose UE is not in network, B also needed earlier purpose UE to be initiated paging.

Further, in above-mentioned dynamic service flow allocation method, the user between all business data transmission can be carried on the same Business Stream; On the other hand, also can distribute different Business Streams according to the QoS grade of business datum, for example, data service can be transmitted on different Business Streams with speech business.

In specific implementation process, above-mentioned source UE and object UE can be the UE of same BTS management, also can be the UE of different base station management, can preestablish needs the local user who transmits of foundation right, with these users to being kept at IAD or base station, when request message is set up at the Business Stream that receives source UE transmission in IAD or base station, can be according to the address information of source UE and purpose UE, judge whether to be used for the local Business Stream of transmitting for source UE and purpose UE set up, in judged result is under the situation that is, carries out this locality according to above-mentioned flow process and transmits.

And, said method can also be applied to not comprise in the flattening wireless network of relay station, in this network configuration, because the base station has the function of IAD, therefore, the function of being finished by IAD is in the foregoing description finished by the base station in this network configuration.

According to the above-mentioned data transmission method that the embodiment of the invention provides, can in the wireless network that does not comprise relay station, realize the local forwarding capability of base station.

According to the embodiment of the invention, another kind of data transmission method also is provided, this method is used for comprising the wireless network of relay station, realizes the local forwarding capability of relay station.

Fig. 5 is the flow chart according to the data transmission method of the embodiment of the invention, as shown in Figure 5, mainly may further comprise the steps (step S501-step S505) according to the data transmission method of the embodiment of the invention:

Step S501: set up the local Business Stream of transmitting, by the base station assigns empty link address corresponding of relay station or this relay station correspondence with Business Stream;

Step S503: the data that source UE will give the purpose subscriber equipment by above-mentioned Business Stream send to relay station;

Step S505: relay station receives data, resolve this data, obtain the empty link address of the Business Stream between relay station and the purpose UE, the above-mentioned data map that receives is transmitted to purpose UE on this empty link address, wherein, the Business Stream of Business Stream between relay station and the purpose UE and source UE transmission data use has mapping relations.

In specific implementation process, in comprising the general wireless network of IAD, setting up the local Business Stream of transmitting can be finished by IAD, in the flattening network, because the function of IAD that the base station is integrated with general base station, therefore, local foundation of transmitting Business Stream can be finished by the base station.
