Fig. 2 is the schematic flow diagram of the data transmission method 200 of wireless network according to embodiments of the present invention.As shown in Fig. 2 method 200 includes：
210:PDN connections are sent to base station according to the VLAN messages of reception and set up request message, wherein the information that request message carries the VLAN tag of the VLAN messages is set up in PDN connections；
220:The PDN connection establishment response message that the base station is sent is received, wherein the PDN connection establishment responses message carries the base station according to the IP address that the information of the VLAN tag is PDN connections determination；
230:The message payload that the VLAN messages are sent to the base station is connected by the PDN, the VLAN messages that the message payload Shi Lost are abandoned after the VLAN tag, so that the base station obtains the information of the VLAN tag according to the IP address of the PDN connections, and the base station is determined the VLAN tag according to the information of the VLAN tag, then the VLAN tag is attached in the message payload of the VLAN messages.
The method for describing the embodiment of the present invention in detail below in conjunction with specific example.
The AP being connected with UE may support at least one VLAN, and these VLAN are identified by VLAN（VLAN Identifier, cylinder claims VID) distinguish.Data are transmitted by VLAN messages between each VLAN.VLAN messages include the VLAN tag of 4 bytes, specifically, and VLAN labels include the tag protocol identifier of 2 bytes（Tag Protocol Identifier, cylinder claims TPID), the priority of 3 bits（), Priority the canonical format indicator of 1 bit（Canonical Format Indicator, cylinder claims CFI) and 12 bits VID.In general, TPID value is 0x8100.
In LTE system, PDN connections are set up in order to ensure that UE is always online, between UE and base station Acquiescence IP carrying.If UE is received from vlan network, such as non-VLAN messages of the AP from vlan network, then UE sends the non-VLAN messages in the acquiescence IP carryings of PDN connections to base station.
When UE receives the VLAN messages of vlan network transmission in step 210, UE sends PDN connections to base station and sets up request message, wherein the information that request message carries the VLAN tag is set up in PDN connections.In a kind of possible implementation, PDN connection request messages can carry all 4 fields, i.e. TPID, Priority of VLAN tag, CFI and VID.In alternatively possible implementation, in view of TPID-as acquiescence value be 0x8100, then PDN connection requests can carry 3 fields of VLAN tag, i.e. Priority, CFI and VID, without carrying TPID.
According to embodiments of the present invention, the information of the VLAN tag can be carried in the APN fields that request is set up in PDN connections.
In a step 220, UE receives the PDN connection establishment response message for being directed to PDN connections foundation request that base station is sent, and the PDN connection establishment responses message carries the base station according to the IP address that the information of the VLAN tag is PDN connections determination.That is, establishing the IP carryings of PDN connections between UE and base station, the IP address of IP carryings is determined according to VLAN tag.In the case where VLAN tag is carried in the APN fields that request is set up in PDN connections, the IP carryings for the PDN connections set up between UE and base station, the IP address that the IP is carried is determined according to the content of APN fields, namely IP address is determined according to VLAN tag.
Then, in step 230, the message payload of VLAN messages is passed through the PDN linkup transmits to base station by UE.Base station can obtain the information of VLAN tag according to the IP address of the PDN connections, and the VLAN tag is determined according to the information of the VLAN tag, then the VLAN labels are attached in the message payload of the VLAN messages, reappear the VLAN messages.Thus, message payload and VLAN tag are sent to base station by VLAN messages by different approaches, and reappear the VLAN messages by base station, are then forwarded to transmission network.For example, the information of the VLAN tag for the VLAN that UE is supported is as follows：
TPID: 0x8100;
Priority: 3;
CFI: 1;
VID: 100。
The PDN connections that then UE is sent to base station are set up in request, and APN can be in VLAN tag TPID, Priority, CFI and VID value is sequentially connected in series, i.e. 81007064, each of which position represents 4 bits in VLAN tag, or the direct character string 1,000 0,001 0,000 0,000 0,111 0,000 0,110 0100 using TPID, Priority, CFI and VID of binary representation is used as APN.When base station is PDN connections distribution IP address according to APN, using every 8 of the character string as a field, according to the decimal form of this 8 two-stage system numbers, 129.0.112.100 can be distributed as the IP address of the PDN connections.
Generally, TPID acquiescence value is 0x8100, therefore according to embodiments of the present invention, when setting up PDN connections, the APN that PDN connections are set up in request can not carry TPID information, it is sequentially connected in series using the value of Priority, CFI and VID in VLAN tag as the APN, such as using 7064 as APN, or using 0,111 0,000 0,110 0100 is used as APN.When IP address is distributed in base station according to APN for institute PDN connections, can using TPID acquiescence value 0x8100 as IP address the first two field.
Using similar mode, the multiple VLAN that can be supported for UE set up different PDN connections respectively, and the IP address of these PDN connections is different.
Under 802.1Q nesting 802.1Q (QinQ), i.e. double layer VLAN application scenarios, the content of VLAN report label.For example, the TPID of inner VLAN label is 0x8100, and the TPID of outside VLAN label is 0x9100.The CFI and VID of inner VLAN label may also be distinct from that the CFI and VID of outside VLAN label.Under this application scenarios, in order to which the information completely of VLAN tag is transferred into base station, when setting up PDN connections, the PDN connections that UE is sent to base station are set up in request, can be by TPID, Priority of inner VLAN label, CFI and VID and outside VLAN label TPID, Priority, CFI and VID are included in APN fields.When base station is that PDN connections distribute IP address, only consider the Priority of inner VLAN label, CFL VID and outside VLAN label Priority, CFI and VID, and the TPID of the TPID of inner VLAN label and outside VLAN label is preserved in a base station.Pass through in base station set up PDN connections receive UE transmission message payload when, according to the IP address of the PDN connections, obtain the Priority of inner VLAN label, CFL VID and outside VLAN label Priority, CFL VID, with reference to the TPID and the TPID of outside VLAN label for preserving inner VLAN label in a base station, recover inner VLAN label and outside VLAN label, and be attached in the message payload, double layer VLAN message is then transmitted to transmission network.
According to alternatively possible embodiment, in double layer VLAN application scenarios, inner VLAN The TPID of label and the TPID of outside VLAN label can be preset in UE and base station.In this case, when setting up PDN connections, the information of the VLAN tag carried in request message is set up in the PDN connections that UE is sent to base station, the TPID of inner VLAN label and the TPID information of outside VLAN label can not be carried, and only carry the Priority of inner VLAN label, CFI, VID and outside VLAN label Priority, CFI and VID.When base station is that PDN connections distribute IP address, the Priority of inner VLAN label, CFL VID and outside VLAN label Priority, CFI and VID are also only considered.Pass through in base station set up PDN connections receive UE transmission message payload when, according to the IP address of the PDN connections, obtain the TPID of the default inner VLAN label and TPID of outside VLAN label, recover inner VLAN label and outside VLAN label, and be attached in the message payload, double layer VLAN message is then transmitted to transmission network.For example, the information of the double layer VLAN label for the VLAN that UE is supported is as follows：
Inner VLAN label：
TPID: 0x8100;
Priority: 3;
CFI: 1;
VID: 100。
Outside VLAN label：
TPID: 0x9100;
Priority: 2;
CFI: 1;
VID: 101。
The PDN connections that UE is sent to base station are set up in request, APN fields can include TPID, Priority in ectonexine VLAN labels, CFI and VID value is sequentially connected in series, i.e. 8100706491005065, each of which position represents 4 bits in VLAN tag, or TPID, Priority of the direct ectonexine VLAN tag with binary representation, CFI and VID character string 1,000 0,001 0,000 0,000 0,111 0,000 0,110 0,100 1,001 0,001 0,000 0,000 0,101 0,000 0,110 0101 are used as APN.When IP address is distributed in base station according to APN for the PDN connections set up, the Priority, CFL VID of ectonexine VLAN tag are only considered, it is possible to distribute 112.100.80.101 as the IP address of the PDN connections.The TPID of ectonexine VLAN tag:0x8100 and 0x9100 are then preserved in a base station. Using similar mode, the multiple double layer VLANs that can be supported for UE set up different PDN connections respectively, and the IP address of these PDN connections is different.
If UE receives the double layer VLAN message of AP transmissions, its ectonexine VLAN tag is as above described in example, then UE terminates the VLAN tag of the double layer VLAN message, pass through the PDN connections that IP address is 112.100.80.101, message payload is sent to base station, base station is received after message payload, according to the IP address of the PDN connections, and combine the TPID for preserving in a base station or presetting ectonexine VLAN tag in a base station, recover the double layer VLAN label, then it is attached on message payload, then is sent to transmission network.
According to embodiments of the present invention, by setting up the message transmitted in PDN connection procedures, VLAN labels are passed into base station by eating dishes without rice or wine, can realize that VLAN messages are eated dishes without rice or wine transparent transmission by LTE, and extra expense will not be introduced, interface-free resources are saved.Moreover, the solution of the present invention meets 3GPP PDCP agreements, the multiplexing with the base station based on covering is realized, networking cost is reduced.
