Transmission link transmission quality.
Technical scheme provided in an embodiment of the present invention, it is adaptable to what UMTS/LTE and wlan network coexisted
Scene:
Grouping system (Evolved Packet System, the EPS) system of evolution is one and supports various accesses
Ambulant system between technology and various accesses.Under multiple access scene, terminal is likely to be at multiple 3GPP
(3rd Generation Partnership Project, third generation partner program) and/or non-3 GPP access
Under the collectively covering of network.These access networks may use different access technologies, may belong to different
Operator, it is also possible to which the access of different core network is provided to.UMTS/LTE and wlan network Coexisting Field
Scape is as shown in figure 1, in the base station (the Node B in UMTS, the eNB in LTE) of UMTS/LTE
In coverage, there is the access point (Access Point, AP) of multiple WLAN.The covering of access point
Scope is smaller with respect to for base station.
It is as follows with regard to Long Term Evolution WLAN aggregation transfer technology introduction:
Framework one:Carry and separate
Referring to Fig. 2, connections of the UE on base station (Master eNB) can have independent carrying.UE exists
The connection of AP is that a part of data distribution that the same EPS on base station is carried is transmitted on AP, should
EPS carries PDCP entities still in base station, and is have independent WLAN layers 2 real on WLAN AP
Body, including medium education (Media Access Control, the MAC) layer and physics of WLAN
(PHYsical, PHY) layer.
Framework two:Carry shunting
Referring to Fig. 3, connections of the UE on base station (Master eNB) can have independent carrying.UE exists
The connection of AP is that the total data that the same EPS on base station is carried is diverted on AP to transmit, the EPS
Carrying can have (can also not have) that PDCP entities are in base station, and have independent on WLAN AP
2 entity of WLAN layers, including the MAC layer and PHY layer of WLAN.
It is described below with regard to Long Term Evolution WLAN aggregation transfer adaptation layer:
In order to support the differentiation of the corresponding PDCP entities of the PDCP bags transmitted through WLAN in UE sides
Problem, introduces Long Term Evolution WLAN aggregation transfer adaptation layer.Mark including at least carrying in its header
Know (Bearer ID) information.Long Term Evolution WLAN after adding adaptation layer under both the above framework gathers

Termination, WT) be WLAN sides for the logic function destination node of 3GPP networks, can be AP
Can also realize on access controller (Access Controlor, AC).
The embodiment of the present invention finds that the link monitoring method of existing WLAN is more single, is mainly based upon
UE is for beacon frame (Beacon Frame) and its detection of signal strength signal intensity of WLAN, and is dependent on UE more
Self-actualization, lacks unified standard, therefore cannot ensure conforming performance, otherwise needs modification existing
WLAN chips.Importantly, existing method can only partial reaction WLAN eat dishes without rice or wine link condition, no
The situation of AP channel congestions can be monitored, can not monitor from base station Jing WLAN to UE it is complete (end to
End) link circuit condition, and the latter, for the data transmission quality ability of Long Term Evolution WLAN aggregation transfer
It is the most key.
Therefore, embodiment of the present invention technical scheme is mainly by the transmission detection bag in base station side periodically (T1)
(Probe Packet), Jing WLAN are transmitted to UE side.If UE sides are not received by some cycles
Detection bag, then it is assumed that Long Term Evolution WLAN aggregation transfer link-quality has not reached performance requirement,
Initiate corresponding link failure report (Link Failure Report) process.
Wherein, UE sides cannot receive detection bag, it may be possible to the degradation because WLAN eats dishes without rice or wine, or
It is WLAN AP channel congestions, than if any a large amount of WLAN lateral terminals (STA) or a large number of services, or
Person is evolved base station (eNB) to caused by this section of wire link congestion of WLAN AP.Either because
Above-mentioned which kind of reason, all can bring to the performance of Long Term Evolution WLAN aggregation transfer and be severely influenced, all
Should be avoided or be taken immediate steps, otherwise will be poly- in Long Term Evolution WLAN to UE
The regular traffic closed under transmission brings baneful influence.
