Text makees further parsing, is sent to other network nodes to obtain complete IP packet, and the IP that other network nodes are returned
Message returns again to after first making preliminary encapsulation to the access point work further encapsulation without complete protocol layer structure.
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
In the embodiment of the present invention, wireless network convergence-level can be used as a function module setting to be set in Radio Access Network
It is standby interior, it may be set to be an independent device.
In pretreatment stage, by taking equipment for radio access network is macro base station as an example, if wireless network convergence-level is located at macro base
In standing, then under 4G network environments, wireless network convergence-level obtains access point based on the interface between macro base station and access point to be made
Protocol layer architecture, interface here refers to X2 interface, as shown in Figure 1.For other network environments, such as 3G, the network of 2G
Environment, transfer of the wireless network convergence-level based on other network elements being at this moment located in macro base station are transmitted, and obtain what access point used
Protocol layer architecture.Wireless network convergence-level continues to judge that the protocol layer architecture that access point uses is compared to complete protocol layer structure
No to lack at least one protocol layer, complete protocol layer structure completes the interaction between terminal and other network nodes for transfer.
In addition, equipment for radio access network can also be base station controller, wireless access gateway etc..
Correspondingly, in pretreatment stage, if wireless network convergence-level is self-contained unit, wireless network convergence-level passes through finger
Stationary interface obtains the protocol layer architecture of each access point, and judges protocol layer architecture that access point uses compared to complete protocol layer
Whether structure lacks at least one protocol layer, and complete protocol layer structure is completed for transfer between terminal and other network nodes
Interaction.In this case, macro base station is also required to access wireless network convergence-level, but since macro base station has complete agreement
Layer structure, therefore downlink message is transmitted in a manner of transparent transmission in wireless network convergence-level thereon, this point is not in this implementation
Example discusses in range.
When access point is registered to network, wireless network convergence-level can know the protocol layer architecture of access point, and sentence
Whether the protocol layer architecture of breaking lacks at least one protocol layer compared to complete protocol layer structure；Therefore Message processing is being carried out
When, wireless network convergence-level has learned which kind of protocol layer access point lacks.
Wireless network convergence-level is the logical functional entity for having complete protocol layer structure, it can be with other network nodes
Directly interact.Wherein, protocol layer (also known as protocol sublayers) substantially refer to for execute and complete certain specific functions or
The logic entity or module of processing operation.
As shown in fig.4, in the embodiment of the present invention, the detailed process that message is sent is as follows：
Step 400：When wireless network convergence-level receives the uplink message that terminal is sent through access point, according to the mark of access point
The protocol layer negotiation information known information and pre-saved, determines the protocol layer architecture that access point uses.
Uplink message is sent to access point by terminal, and access point tentatively solves message according to the protocol layer architecture of itself
Analysis, and the message after Preliminary Analysis is sent to wireless network convergence-level.
In pretreatment stage, wireless network convergence-level has been obtained for the protocol layer architecture that access point uses, wireless network
Convergence-level would know that the identification information of access point being established with access point when communication connection.At this point, wireless network convergence-level is only
The protocol layer negotiation information pre-saved before need to can be found according to the identification information of access point, and then determines that access point uses
Protocol layer architecture.
Step 410：The protocol layer architecture that wireless network convergence-level is used according to access point determines that access point lacks at least one
When kind protocol layer, uplink message is parsed using at least one protocol layer, and the uplink message after parsing is sent to it
His network node.
Specifically, the protocol layer architecture used according to access point, the Preliminary Analysis sent through access point for terminal
Uplink message, the protocol layer that wireless network convergence-level is lacked using access point further parses message, and will most
The uplink message being parsed eventually is sent to other network nodes.
For example, it is assumed that the protocol layer architecture of access point is PHY layer and MAC layer, then (terminal has complete protocol layer to terminal
Structure) send uplink message carry out PHY layer parsing and MAC layer parsing, obtain two layers of data, be then forwarded to wireless network
Convergence-level.Uplink message of the wireless network convergence-level by terminal by two layers of parsing makees further parsing, including, using rlc layer
MAC layer and PHY layer protocol data are recombinated, merged, error correction, re-transmission, redundancy detection etc., will be on rlc layer using PDCP layers
Pass each RLC data packets be decrypted, IP decompress, be sequentially merged into data block, give IP layers, IP layers in this data
It can be sent to other network nodes after being handled as IP packet on block.
In addition, it is further, in the protocol layer architecture that wireless network convergence-level is used according to access point, determine that access point lacks
After few at least one protocol layer, before being parsed to uplink message using at least one protocol layer, if uplink message is taken
Band wireless control signaling information, then wireless network convergence-level uplink message is sent to control interface and carries out follow-up dissection process；
If uplink message carries service data information, the information for the protocol layer that wireless network convergence-level lacks according to access point will be upper
Row message is sent to corresponding data-interface and carries out follow-up dissection process.I.e. different types of information passes through different types of interface
Subsequent processing is carried out into wireless network convergence-level, and same type of information parses degree according to it and passes through different analytic abilities
Interface enter wireless network convergence-level and handled.
For example, it is assumed that the protocol layer architecture of access point is PHY layer and MAC layer, wireless network convergence-level needs to parse data
The uplink message of type determines that the access point lacks rlc layer, PDCP layers and IP layers association according to the protocol layer architecture that access point uses
Layer is discussed, uplink message is at this moment sent to corresponding data-interface, i.e., enters from the processing board of rlc layer, pass sequentially through from rlc layer
Plate, PDCP layers of processing board and IP layers of processing board are managed, the uplink message being parsed finally is sent to other network nodes.
As shown in fig.5, in the embodiment of the present invention, the detailed process that message is sent is as follows：
Wireless network convergence-level is consistent with the pretreatment stage of uplink message to downlink message pretreatment stage.
Step 500：When wireless network convergence-level receives the downlink message that other network nodes are issued for terminal, determine eventually
The belonged to access point in end, and connect according to the identification information of access point and the protocol layer negotiation information pre-saved, determination
The protocol layer architecture that sink uses.
Step 510：The protocol layer architecture that wireless network convergence-level is used according to access point determines that access point lacks at least one
When kind protocol layer, downlink message is packaged using at least one protocol layer, and the downlink message after encapsulation is sent to and is connect
Access point.
Specifically, the protocol layer architecture used according to access point, the downlink message of terminal is issued for other network nodes,
Wireless network convergence-level is packaged message using the protocol layer that access point lacks, and the downlink message after encapsulation is sent to
Access point.Access point carries out bottom to the protocol layer architecture that the downlink message that wireless network convergence-level tentatively encapsulates is used according to itself
The further encapsulation of layer protocol layer, and the downlink message that final encapsulation is completed is sent to terminal user.
For example, it is assumed that the protocol layer architecture of access point is PHY layer and MAC layer, when other network nodes are issued for terminal
When downlink message, wireless network convergence-level receives downlink message, and the IP packet head for removing downlink message using PDCP layers has obtained
Whole PDCP data blocks are segmented PDCP data blocks using rlc layer, are encapsulated as several RLC data packets, and will carry
The downlink message of several RLC data packets is sent to access point and carries out MAC layer encapsulation and PHY layer encapsulation, the knot for finally completing encapsulation
Fruit is sent to terminal.
In addition, it is further, in the protocol layer architecture that wireless network convergence-level is used according to access point, determine that access point lacks
After few at least one protocol layer, before being packaged to downlink message using at least one protocol layer, if downlink message is taken
Band wireless control signaling information, then wireless network convergence-level downlink message is sent to control interface and carries out follow-up encapsulation process；
If downlink message carry service data information, the information for the protocol layer that wireless network convergence-level lacks according to access point, will under
Row message is sent to corresponding data-interface and carries out follow-up encapsulation process.I.e. different types of information passes through different types of interface
Subsequent processing is carried out into wireless network convergence-level, and same type of information encapsulates degree also by different encapsulation energy according to it
The interface of power enters wireless network convergence-level and is handled.
For example, it is assumed that the protocol layer architecture of access point is PHY layer and MAC layer, wireless network convergence-level needs encapsulation of data
The downlink message of type determines that the access point lacks rlc layer, PDCP layers and IP layers association according to the protocol layer architecture that access point uses
Layer is discussed, downlink message is at this moment passed sequentially through into IP layers of processing board, PDCP layers of processing board and rlc layer processing board, finally from rlc layer
Encapsulation of the plate completion to downlink message is managed, and the downlink message for encapsulation being completed from the corresponding data-interface of rlc layer processing board is sent out
Give access point.
As shown in fig.6, the embodiment of the present invention also provide it is as follows for the specific implementation process of message transmission process：

Data access point 3 carries out Preliminary Analysis according to the protocol layer architecture of itself to message, can only be resolved to MAC layer here
And PHY layer, the message after Preliminary Analysis is then sent to wireless network tether layer.
Because uplink message carries service data information, the association that at this moment wireless network convergence-level lacks according to data access point 3
The information for discussing layer, is sent to corresponding data-interface 3 by uplink message and carries out follow-up dissection process.
Finally, the protocol layer architecture that wireless network convergence-level is used according to access point determines that data access point 3 lacks RLC
Layer, PDCP layers and IP layer protocol layers, therefore rlc layer, PDCP layers and IP layers of function needs are completed by wireless network convergence-level.Needle
To the uplink message for the Preliminary Analysis that terminal is sent through data access point 3, wireless network convergence-level is using RLC to MAC layer and PHY
Layer protocol data are retransmitted, and each RLC data packet compressings that rlc layer uploads are merged into a data block using PDCP layers,
IP layers are given, IP layers can be sent to other network nodes in this data block after addition IP packet head.
Equally, the downlink message of terminal is issued for other network nodes, wireless network convergence-level determines that terminal is belonged to
Access point be data access point 3, according to the identification information of data access point 3 and the protocol layer negotiation information pre-saved,
Determine the protocol layer architecture that data access point 3 uses.
Because downlink message carries service data information, the association that at this moment wireless network convergence-level lacks according to data access point 3
The information for discussing layer, is sent to corresponding data-interface 3 by downlink message and carries out follow-up dissection process.
Finally, the protocol layer architecture that wireless network convergence-level is used according to access point determines that data access point 3 lacks RLC
Layer, PDCP layers and IP layer protocol layers, therefore rlc layer, PDCP layers and IP layers of function needs are completed by wireless network convergence-level.Needle
Other network nodes are issued with the downlink message of terminal, wireless network convergence-level uses the PDCP layers of IP packet for removing downlink message
Head obtains complete PDCP data blocks, is segmented to PDCP data blocks using rlc layer, is encapsulated as several RLC data packets, with
And the downlink message for carrying several RLC data packets is sent to access point and carries out MAC layer encapsulation and PHY layer encapsulation, it finally will envelope
The result installed is sent to terminal.
