(1) step S101

In order to make the base station have local transfer capability, in embodiments of the present invention, at first to be configured to man-to-man user right for all UE that this base station is administered, and be each user to the one or more Business Streams of static configuration, and in the attribute of Business Stream, carry the physical address of this user's centering opposite end UE; Then, be the corresponding special-purpose empty link address of each traffic flow assignment by the base station.Source UE is when sending data to opposite end UE, physical address according to opposite end UE eats dishes without rice or wine data map to connect to corresponding special use, the user profile of the empty link address acquisition opposite end UE of resolution data is passed through in the base station, and data are transmitted to opposite end UE in this locality on corresponding downstream eats dishes without rice or wine to connect.

The data transmission method that provides according to the embodiment of the invention can be applied to traditional access network, also can be applied to the flattening network, for traditional access network of forming by IAD, base station and terminal, the foundation of the Business Stream that the configuration that the user is right and each user are right can be finished or be initiated by IAD, particularly, IAD is that all UE that the base station is administered are configured to the user to also finishing according to following steps for each user's distribution service stream:

Step 1: the IAD corresponding with the base station judges whether the current wireless access network supports the local forwarding capability of data, when if this function is not activated, the data transmission method of the side of then eating dishes without rice or wine adopts current mechanism, if base station or IAD are enabled this function, then to be configured to the user right for IAD all UE that the base station is administered;

Particularly, when the UE that administers when the base station add up to N, then the quantity that the user is right was

Such as, suppose that the UE that a certain base station is administered comprises: UE A, UE B and UEC, then that the UE under this base station is made into three users is right for IAD: UE A and UE B, UE A and UE C, UE B and UE C.

Step 2: right for each user, IAD for this user to distributing one or more Business Streams, in the attribute of each Business Stream, carry the physical address of user's centering opposite end UE, and the information of each Business Stream sent to the base station.

Step 3: the base station is distributed corresponding empty link address according to the information of each Business Stream for it.

In specific implementation process, above-mentioned steps 1 specifically can realize by following signaling process:

1. IAD sends Business Stream by the base station respectively to two right UE of user and sets up request message, and be the corresponding special-purpose empty link address of each traffic flow assignment by the base station, wherein, this Business Stream is set up the information of carrying in the request message and is included but not limited to one of following parameter at least: address information, port numbers and the protocol type of two UE that the user is right;

2. two UE that the user is right set up request message in response to above-mentioned Business Stream, send Business Stream by the base station to IAD and set up response message;

3. IAD sends Business Stream by the base station to two right UE of user and sets up acknowledge message.

So far, the Business Stream that this user is right is set up and is finished, no matter this user between whether have data interaction, the base station all is that this user is to disposing one or more Business Streams, after Business Stream foundation was finished, source UE was when sending data to opposite end UE, according to the physical address of opposite end UE, obtain and this physical address corresponding service stream, use grader that data map is eated dishes without rice or wine to connect transmission to the special use corresponding with this Business Stream.

In specific implementation process, IAD can for each user to distributing one or more Business Streams.When IAD for the user to only distribute dedicated service stream to the time, all data that this user is right all are mapped to this Business Stream to last, and use corresponding empty link address to transmitting.When IAD for the user to distribute a plurality of dedicated services stream to the time, the data that this user is right can be according to quality of service (quality of service, abbreviate QoS as), parameters such as data transfer direction are mapped on the different Business Streams, and use corresponding empty link address to transmit respectively.

In specific implementation process, IAD configure user to the time, it is right also the UE that a plurality of base station under it is administered can be configured to the user, and be that each user is to distributing one or more Business Streams, when the source UE of these user's centerings sends data to opposite end UE, also can send data according to pre-configured Business Stream.

For the flattening network of forming by base station and terminal, since in the flattening network base station integrated the function of traditional base station and IAD, therefore, can finish the foundation of the right Business Stream of the right configuration of user and each user by the base station, particularly, the base station is configured to the user to also finishing according to following steps for each user's distribution service stream for its all UE that administer:

Step 1: the base station judges whether the current wireless access network supports the local forwarding capability of data, when if this function is not activated, the data transmission method of the side of then eating dishes without rice or wine adopts current mechanism, if enable this function, then that its all UE that administer are configured to the user is right in the base station; Particularly, when the UE that administers when the base station add up to N, the quantity that the user is right was

Such as, suppose that the UE that a certain base station is administered comprises: UE A, UE B and UE C, then that these UE are made into three users is right: UE A and UE B, UE A and UE C, UE B and UE C in the base station.

Step 2: right for each user, the base station for this user to distributing one or more Business Streams, in the attribute of each Business Stream, carry the physical address of user's centering opposite end UE.

1. the base station sends Business Stream respectively to two right UE of user and sets up request message, and wherein, this Business Stream is set up the information of carrying in the request message and included but not limited to one of following parameter at least: address information, port numbers and the protocol type of two UE that the user is right;

2. two UE that the user is right set up request message in response to above-mentioned Business Stream, send Business Stream to the base station and set up response message;

3. the base station sends Business Stream to two right UE of user and sets up acknowledge message.

So far, the right Business Stream of this user is set up and is finished, no matter this user between whether have data interaction, for this user exists one or more Business Streams of configuration, set up in the process at Business Stream, the base station is the corresponding special-purpose empty link address of each traffic flow assignment.Source UE according to the physical address of opposite end UE, obtains and this physical address corresponding service stream, and data map is eated dishes without rice or wine to connect transmission to the special use corresponding with this Business Stream when sending data to opposite end UE.

In specific implementation process, the base station can for each user to distributing one or more Business Streams.When the base station for the user to only distribute dedicated service stream to the time, all data that this user is right all are mapped to this Business Stream to last, and use corresponding empty link address to transmitting.When the base station for the user to distribute a plurality of dedicated services stream to the time, the data that this user is right can be mapped on the different Business Streams according to parameters such as QoS, data transfer directions, and use corresponding empty link address to transmit respectively.

In specific implementation process, may there be following three kinds of situations for each user in IAD or base station to the Business Stream of setting up:

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; Accordingly, Business Stream eat dishes without rice or wine to be connected to originate in the user to, the ascending idle port that ends at the base station connects and originate in the base station, end at the right downlink space interface of user connects.

Under this kind situation, if base station and user are to having existed suitable downstream service flow between (comprising source UE and purpose UE), then do not need to rebulid new downstream service flow, only need set up the mapping relations of uplink service stream and existing downstream service flow, and set up the mapping relations of the corresponding empty link address of this uplink service stream empty link address corresponding with this existing downstream service flow.This uplink service stream can only carry from source UE, send to the upstream data of opposite end UE, and this downstream service flow not only carries from source UE, sends to the downlink data of opposite end UE, can also carry the data that other users issue opposite end UE.

In specific implementation process, source UE is when sending data, by above-mentioned uplink service stream, data map to be sent is sent to the base station on the empty link address corresponding with this uplink service stream, after the base station receives above-mentioned data, obtain the empty link address of the downstream service flow corresponding, the data map that receives is sent to opposite end UE on the empty link address corresponding with this downstream service flow with the empty link address of this uplink service stream.

Two, Business Stream is the one-way traffic flow end to end that originates in source UE, ends at opposite end UE via the base station; Accordingly, the eating dishes without rice or wine to be connected to of this Business Stream originates in source UE, and unidirectional the eating dishes without rice or wine of ending at opposite end UE via the base station connects;

Under this kind situation, the user between need set up two one-way traffic flows, article one one-way traffic flow is: UE → base station, source → opposite end UE, the second Business Stream is: UE → base station, opposite end → source UE.Wherein, article one Business Stream only carries from source UE, sends to the data of opposite end UE, and the second Business Stream only carries from opposite end UE, sends to the data of source UE.

In specific implementation process, source UE is when opposite end UE sends data, by article one Business Stream, data map to be sent is sent to the base station on the empty link address corresponding with this Business Stream, the data that base station reception sources UE sends, by this Business Stream, the data map that receives is transmitted to opposite end UE to the empty link address corresponding with this Business Stream.Equally, for opposite end UE, when it sends data to source UE, opposite end UE is by the second Business Stream, data map to be sent is sent to the base station on the empty link address corresponding with this Business Stream, the base station is transmitted to source UE with the data map that receives to the empty link address corresponding with this Business Stream by this Business Stream.

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; Accordingly, this Business Stream eat dishes without rice or wine be connected to source UE and be connected with two-way eating dishes without rice or wine between the UE of opposite end via the base station.

Under this kind situation, the user between only need set up a Business Stream.This Business Stream only carries source user and to data mutual between the end subscriber, source UE is when opposite end UE sends data, by this two-way services stream, data map is sent to the base station with data on the empty link address corresponding with this two-way services stream, the data commentaries on classics that the base station sends source UE by this two-way services stream is mapped on the empty link address corresponding with this two-way services stream and issues opposite end UE, equally, when opposite end UE has data will send to source UE, opposite end UE sends the data to the base station by this two-way services stream, and the base station sends source UE by this two-way services stream with data.

(2) step S103

After the base station receives the data of source UE transmission by the Business Stream of setting up in advance, by resolving the empty link address corresponding with this Business Stream, can obtain the user profile of purpose UE, particularly, this user profile can be physical address, particularly, physical address includes but not limited to: the IP address of UE, the port numbers of UE.

In specific implementation process, when data are transmitted in this locality in the base station, can be with Medium Access Control (MAC) Protocol Data Unit (Protocol data unit, abbreviate PDU as) be reassembled as service data unit (Service Data Unit, abbreviate SDU as), and repack SDU for MAC PDU and be transmitted to purpose UE according to the link between base station and the purpose UE and scheduling situation.

In specific implementation process, if the user profile of its all UE that administer is preserved in the base station, then the base station can be by resolving physical address and the pairing source UE of this Business Stream of the purpose UE in the Business Stream, by inquiring about the user profile of local its all UE that administer that preserve, can judge whether source UE and purpose UE all are its UE that administers, thereby judge whether this Business Stream is the local Business Stream of transmitting, particularly, if the UE that source UE and purpose UE administer for this base station, then the base station determines that this Business Stream is the local Business Stream of transmitting, the base station obtains the downstream service flow corresponding with this Business Stream, and the data forwarding that source UE is sent by this downstream service flow is to purpose UE.

If the user profile of its UE that administers is not preserved in the base station, then can be by in Business Stream, carrying the local sign of transmitting Business Stream, the base station is by resolving this sign, can determine that current business flow is the local Business Stream of transmitting, the base station obtains the downstream service flow corresponding with this Business Stream, and the data forwarding that source UE is sent by this downstream service flow is to purpose UE.
