Description
Technical field
The present invention relates to the communications field, particularly relate to method for building up and the device of a kind of Data Radio Bearer.
Background technology
Along with wireless communication technology and the continuous evolution of standard, mobile Packet Service has obtained huge development,
The data throughput capabilities of unit/terminal is constantly promoting.With Long Term Evolution (Long Term Evolution, LTE)
As a example by system, can support that in 20M bandwidth the data of descending maximum rate 100Mbps are transmitted, after
In LTE (LTE Advanced) system of continuous enhancing, the transfer rate of data will promote further,
Even can reach 1Gbps.
The growth of terminal data portfolio expansion type, makes existing Internet resources the most unable to do what one wishes, especially
It is in the case of a new generation's communication technology (such as 3G, LTE) also cannot extensively arrange net, thereupon
Be user rate and traffic demand cannot meet, the variation of Consumer's Experience.How to prevent and to change this
Situation is the problem that operator must take into, and on the one hand needs to accelerate popularization and the network design of new technique；
On the other hand, it is desirable to be able to by existing network and technology are strengthened, to reach fast lifting network
The purpose of performance.It is well known that at third generation partner program (The 3rd Generation
Partnership Project, 3GPP) outside the radio network technique that provides, the most commonly used
WLAN (Wireless Local Area Network, WLAN), is based especially on electric and electric
Sub-SE (Institute of Electrical and Electronics Engineers, IEEE) 802.11
The WLAN of standard has been widely used in focus access and has covered in family, enterprise even the Internet
Lid.The technical specification wherein proposed by WiFi alliance (Wi-Fi Alliance) is most widely used, therefore real
In border, WiFi network often follows wlan network based on IEEE 802.11 standard to be equivalent to, and is not drawing
Rise in the case of obscuring, be hereinafter also adopted by WiFi module to describe the nothing supporting WLAN in network node
Line transmitting-receiving and processing module.
Under this premise, some operators and company have been proposed that WLAN and existing 3GPP network
Merge, it is achieved joint transmission, to reach load shunting and to improve the purpose of network performance.3GPP SA2
Pass through access network discovery and selected functional unit (Access Network Discovery Support
Functions, ANDSF) scheme, it is provided that a kind of is that terminal selects target to access according to carrier policy
The pattern of network.
3GPP R10 defines ANDSF standard, and ANDSF realizes Intelligent network-selecting as accessing anchor point,
Worked in coordination with the mutual of terminal by network, it is achieved effective shunting of network insertion, meet following multi-network cooperative
Operation direction.ANDSF formulates based on information such as network load, terminal capability, user's signing situations
Strategy, helps terminal use to select the network formats most preferably accessed, it is achieved the collaborative fortune of plurality of access modes
Battalion.ANDSF both can individually dispose, it is possible to closes with other network element and sets.At present, industry Main Viewpoints
Think that ANDSF can be deployed in scheme on PCC equipment.
ANDSF is a WLAN interworking scheme based on core net, not in view of right
The impact of access network, additionally due to ANDSF is the scheme of a relative quiescent, it is impossible to very well to network
The situation that load and channel quality dynamically change adapts to, and therefore also carries out in 3GPP access network group
WLAN interworking discusses.In the wireless interoperability of R12WLAN/3GPP, perform WLAN
The rule of shunting and the mechanism of triggering are introduced into.
But, it is real-time that core net mechanism and the auxiliary information mechanism from wireless network can not be supplied to network side
Ground uses load and channel condition thus merges use Radio Resource.It addition, from the data of same bearer
Can not service on 3GPP and WLAN link simultaneously.Therefore WLAN Yu 3GPP system integrating
Demand is proposed again RAN65 plenary session.
Compare the WLAN shunt scheme depending on strategy and triggering the most after deliberation, RAN level
WLAN Yu the 3GPP system integrating of polymerization, is called for short WLAN and 3GPP network close coupling, similar
In carrier aggregation and dual link, provide control and the utilization of resource in preferably dual link for overall system.
Compacting into and being polymerized the nothing allowing more combined dispatching WLAN in real time with 3GPP network in radio layer
Line resource, therefore improves user QoS and entire system capacity.By the wireless money between more preferably management user
Source, can increase the collective throughput of all users and provide whole system capacity.Based on Real-time Channel condition
With under system service condition, each link scheduling determines to accomplish each level wrapped.User face anchor
It is scheduled on reliable LTE network, performance can be improved by returning back to LTE network.
WLAN Yu 3GPP network tightly coupled WLAN shunt scheme has four kinds at present: simplify framework
PDCP layer shunts, and the PDCP layer shunting of dual link framework, rlc layer shunts, and MAC layer shunts.
Fig. 1 is WLAN Yu 3GPP network tightly coupled WLAN shunt framework signal in prior art
Figure.In framework shown in Fig. 1, only tightly coupled to WLAN Yu 3GPP network WLAN shunt framework
It is defined, has newly introduced Data Radio Bearer (Data Radio Bearers, DRB), this DRB
Concrete feature is exactly that PDCP layer is in 3gpp network side, the MAC layer of transmission PDCP protocol Data Unit
And physical layer is positioned at wlan network, referred to as 2C DRB based on WLAN, wherein 2C represents
The C option of scheme two.Due to the not new 2C introduced to the close-coupled network system under this framework
DRB sets up the method for configuration and discusses, and the foundation of 2C DRB is that to realize close coupling requisite
One technology.
