Description
Technical field
The present invention relates to the communications field, more particularly to a kind of method and device for carrying out network control.
Background technology
EPS（Evolved Packet System, the grouping system of evolution）It is one and supports a variety of access technologies and a variety of
Ambulant system between access.Under multiple access scene, UE（User Equipment, user equipment）It is likely to be at multiple 3GPP
（3rd Generation Partnership Project, third generation partner program）And/or non-3GPP access network
Collectively cover down.These access networks may use different access technologies, may belong to different operators, it is also possible to provide
To the access of different core network.
For example, under the prior art, UMTS（Universal Mobile Telecommunications System, it is general
Mobile communication system）/LTE（Long Term Evolution, Long Term Evolution）And WLAN（Wireless Local Area
Network, WLAN）Network coexisted scene is as shown in Figure 1.Network node is controlled in the access of UMTS/LTE（Such as, UMTS
In Node B, LTE in eNB）Coverage in, there are the AP of multiple WLAN（Access Point, access point）, access
The coverage of point is smaller with respect to for base station.
Under above-mentioned scene, the network architecture such as Fig. 2 institutes for a kind of UMTS/LTE and the WLAN interoperability supported at present
Show, which is to be based on PDN（Packet DataNetwork, Packet Data Network）S2c interfaces between Gateway and UE come real
Now interoperate.Wherein, the AP of PDN Gateway and WLAN can be handed over the server in Internet into row information
Mutually.Relevant information transmission uses 802.3 agreements.
Correspondingly, back haul link is included between access control network node and PDN Gateway, the AP and PDN of WLAN
Between Gateway and WLAN AP and lead to Internet router between link, PDN Gateway can also be included
With the link between the service server in Internet.
Based on above-mentioned network scenarios and framework, it is to be based on ANDSF to have a kind of network selection mechanism at present（Access
Network Discovery and Selection Function, access network discovery and selection function）Strategy is realized.
Specifically, the framework to communicate between ANDSF and UE is as shown in figure 3, wherein UE and ANDSF is by S14 interactive interfacings, the interface
One is based on IP（Internet Protocol, Internet Protocol）Interface.Communication between UE and ANDSF have Pull and
Push both of which, the former is that UE actively sends request to ANDSF, and the latter is ANDSF active push information.ANDSF strategies are
Comparative static.
Under the prior art, network discovery is provided to UE based on ANDSF strategies and select relevant information, including following three
Class：
The first kind is：ISMP（Inter-system mobility policy, the mobility strategy of cross-system）.
ISMP is the rule and preference information that a series of operators define, and whether which allows cross-system to move
Dynamic, most suitable access EPC（Evolved packet core, the block core of evolution）Access technology type, different access skill
The information such as the different priorities of art.ISMP can be prewired in UE, can also send, can also be existed by ANDSF when UE is asked
UE is pushed under certain triggering.For example, the priority that ANDSF can issue WLAN is higher than the strategy of LTE, in this way, working as UE two
, can the access of prioritizing selection wlan system when under person's covering.
Second class is：ANDI（Access Network Discovery Information, access network discovery information）.
ANDSF can be provided for UE in its vicinity it is available, meet the access network list of requested access style with
And relevant parameter, such as access technology（Such as, WLAN, WiMAX etc.）, Radio Access Network mark, carrier frequency etc..
Three classes are：ISRP（Inter-System Routing Policy, cross-system routing policy）.
ISRP includes some cross-systems route required information, for the UE with more radio access interfaces, e.g., supports
IFOM（IP Flow Mobility, IP flow mobilities）Or MAPCON（Multi Access PDN Connectivity, connect more
Enter PDN connections）UE, these information can be used for determining：
A) when meeting specific route conditions, which kind of available access network data to be sent using;
B) for specific IP traffic and/or specific APN（Access Point Name, access point name）For, certain
When disabled access network.
Existing protocol provide, ANDSF according to Carrier Requirements and roaming agreement selection be supplied to UE ISMP, ANDI and
ISRP, ANDSF can provide above-mentioned three kinds of strategies at the same time, can also only provide partial strategy therein.ANDSF can be with operation
Some databases interaction in business's network, such as HSS（Home Subscriber Server, home subscriber server）, to obtain
Required information.
It is higher than the existing access network information for accessing network when UE receives available priority, if user allows,
UE should go to discovery and the reuse adoption process of the high priority.When UE automatically selects access network, it is impossible to by ISMP
In be marked as the access network insertion forbidden to EPC.
In addition to the network selection mechanism based on strategy, some are also proposed under the prior art based on wireless access network
Network selection mechanism, for example, considering the information such as the channel quality of wireless access network, load, geographical location, then carries out net
Network selects.A kind of possible mode is：UE obtains the geographical location information of WLANAP by the broadcast of UMTS/LTE networks, then
When UE is close to the geographical location, start the scanning to WLANAP, after AP is found, assess its channel quality and load whether
It is adapted to access, after the channel quality and load information that consider UMTS/LTE sides and WLAN sides afterwards, judgement selection UMTS/LT
Network or wlan network.The network selection policies of access net are that comparison is dynamic, can be with such as channel quality, load information etc.
It is changed.Which is to carry out access network selection based on the metrical information eated dishes without rice or wine, for example, being measured by UE on eating dishes without rice or wine
To obtain channel quality of WLAN and UMTS/LTE networks etc..
On the other hand, under the prior art, the circuit link of network side（Hereinafter referred to as circuit）Make usually using Ethernet
To carry medium, Ethernet can be divided into following several according to the cable of actual use：10M:10base-T（Copper wire UTP moulds
Formula）、100M:100base-TX（Copper wire UTP patterns）、100base-FX（Optical fiber cable）、1000M:1000base-T（Copper wire UTP
Pattern）And ten thousand mbit ethernet.
Ethernet has two kinds of flow control modes：Half-duplex and full duplex are in different ways.Half-duplex is using implicit
Flow control（That is back pressure technology）, full duplex is using display flow control（That is MAC sends PAUSE frames）.
Back pressure technology is that Switch controller sends a kind of pseudo- collision alarm technology.Back pressure technology is generally according to buffering
The capacity ratio in area realizes that, when reaching a ratio set in advance with buffer pool size, port will be according to this threshold
Value generation block signal, and when freebuf capacity exceedes another relatively low ratio, port will cancel block signal.
In the network segment where congestion port, the transmission of block signal can make port all in the network segment to detect conflict, etc.
Treat after block signal transmitting data frame again, so as to prevent more to collide, temporarily have ceased the transmission of data, make buffering area
Space be released.
Under full duplex MAC control frameworks, flow control mechanism is realized by PAUSE functions.PAUSE functions can be with
Unnecessary frame loss when causing buffer overflow that prevents instantaneous overload.PAUSE operations realize one kind and simply stop-equation
Flow control mechanism.If some port will stop the reception of frame, a PAUSE frame for carrying parameter can be sent, parameter refers to
Show that full-duplex link other side needs the time waited before transmission data are started.After link other side receives PAUSE frames, joining
Stop sending data in the time that number is specified.Exceed when specified time, or after the releasing of port flow state of a control, former congestion port
The PAUSE frames that operating parameter is 0 are re-emitted, link other side continues to send data frame from the position of pause.
By the content in PAUSE frames, the congestion situation of port can be known.Data can be sent according to stopping in the frame
Frame time length judges the order of severity of congestion.
With the growth of user demand and the development of the communication technology, there are more and more wireless communication techniques and associated nets
Network, such as the 2G/3G/4G mobile communication technologies and network extensively covered can be provided, and the wifi skills of hot spot covering can be provided
Art and wlan network.Therefore also largely there is the scene that different communication networks coexists, as 2G/3G/4G networks and WLAN are total to
The scene deposited.Under these network coexisted scenes, how UE carries out rational network selection, preferably to be serviced and saved
UE electricity, is the problem of needing research.In the prior art, it is main based on tactful or based on wireless access network network selection
The measurement situation of eating dishes without rice or wine of selection strategy and wireless network is considered, however, when access network is selected for UE, not
Consider the circuit of each network（That is backhaul）Situation.And access control node can not obtain whole network side at present
Signal intelligence, it is low in the access network may be selected during network selection load of eating dishes without rice or wine, but its circuit and not smooth so that
The business for influencing UE uses, and reduces the overall performance of system.

Instruction, determines to stop the temporal information sending, and the Congestion Level SPCC of corresponding circuit is judged according to the temporal information；Specially：Such as
The waiting time of fruit PAUSE frames instruction（The waiting time determines according to propagation delay time, when propagation delay time is more than or equal to the wait
It is long）More than the first thresholding, it may be considered that corresponding circuit heavy congestion, if the waiting time of PAUSE frames instruction is less than second
Thresholding, it may be considered that corresponding circuit moderate congestion, if the waiting time of PAUSE instructions is overtime or receives opposite end transmission
Instruction cancel stop frame, while local terminal buffering area take level values be less than some threshold value, it may be considered that corresponding circuit
Not congestion.In another example if also having mass data to overstock in the buffering area of local terminal, it is congestion to be also considered as associated loop.Return
The network node at road both ends can be using the propagation delay time for characterizing each section of circuit Congestion Level SPCC or/and buffering area seizure condition as returning

As shown in Figure 1, in the embodiment of the present invention, WLANAP can be connected to Internet network by PDN Gateway,
Internet network can also be connected directly to, according to the difference of connection mode between WLAN AP and Internet network, base station
The mode of the loop state information in each circuit is also different in acquisition system, specifically, can use but be not limited to following two sides
Formula：
First way is：When WLANAP is connected to Internet network by PDN Gateway, base station can be advance
Increase first kind interface between base station and PDN Gateway（Such as, chain of command interface or S1 interfaces etc.）And set corresponding
Interface message, then, then by first kind interface obtains base station and Internet network from PDN Gateway（That is business service

In practical application, when using above two mode, base station can also voluntarily measure base station and PDN Gateway it
Between circuit loop state information, details are not described herein.
Preferably, base station can directly acquire the circuit shape sent by PDN Gateway by newly-increased first kind interface
State information, can also be obtained by newly-increased first kind interface and be sent by PDN Gateway and by MME（Mobile
Management Entity, mobile management entity）Or Serving Gateway（Gateway）Above-mentioned each time of transparent transmission forwarding
The loop state information on road.Wherein, the circuit shape that PDN Gateway aperiodically can measure itself according to base station requests
State information is sent to base station, and the loop state information that periodically can also be measured itself is sent to base station.
In practical application, when using above two mode, base station can also voluntarily measure base station and PDN Gateway it
Between circuit loop state information, details are not described herein.
On the other hand, in the embodiment of the present invention, the loop state information in every circuit that base station obtains includes at least accordingly
The loop-type information and circuit link quality information in circuit, its particular content can configure as follows：
Loop-type information：The bandwidth for the Ethernet that circuit uses can be included（Such as, 10,000,000,100,000,000, gigabit, 10,000,000,000 etc.
Deng）, circuit use duplex mode（Such as, half-duplex, full duplex etc.）.
Circuit link quality information：It can include to characterize the parameter of circuit Congestion Level SPCC, e.g., during the transmission in circuit
Prolong, alternatively, the buffering area seizure condition in circuit（It can be represented with percentage or level values）.
Step 510：Base station is when judging that UE need to access network or need to carry out network switching, the loop state letter based on acquisition
Breath instruction UE access switches to corresponding objective network.
In base station acquisition system after the loop state information in each circuit, it can combine and eat dishes without rice or wine metrical information or/and to be directed to
ANDSF strategies judgement/decision-making UE access which objective network that UE is formulated, alternatively, judgement/decision-making needs the UE which being switched to
Suitable objective network.
The loop state information in each circuit in the system of acquisition can also be passed through broadcast signaling or dedicated signaling by base station
UE is issued, allows UE to decide in its sole discretion and which objective network is accessed, which objective network switched to alternatively, deciding in its sole discretion, and by target
Network advertisement UE.For example, UE can be supervised according to the loop state information of acquisition with reference to ANDSF strategies, and further combined with UE
The 3G/4G networks listened and measured are eated dishes without rice or wine the load condition and signal quality of signal quality, disturbed condition and wlan network, choosing
Suitable objective network is selected to be accessed or switched.
Certainly, UE can also active request network side provide loop state information, details are not described herein.
In the embodiment of the present invention, when performing step 510, if base station according to the loop state information of acquisition, with reference to eating dishes without rice or wine
Metrical information or/and default ANDSF strategies, determine the objective network of UE access or switching, and the objective network is notified
UE, then base station can be determined based on the loop state information of acquisition each circuit Ethernet bandwidth, use duplex mode and
Propagation delay time or/and buffering area seizure condition, further according to confirmation as a result, with reference to metrical information or/and the default ANDSF plans of eating dishes without rice or wine
Slightly, determine the objective network of UE access or switching, and the objective network is notified into UE.
Specifically can in the following ways in one kind or any combination.
Mode one：According to the circuit confirmed in the currently used networks of result judgement UE congestion occurs for base station, then selectes circuit
Another network that congestion does not occur is the objective network of UE switchings.
For example, Gateway to Internet sections of congestions of PDN, but WLANAP to Internet sections of not congestions, then base station
UE can be triggered to be switched in the network of WLAN.In order to avoid some UE select LTE network, base station can broadcast respectively in the broadcast
The congestion condition of a access net.
Mode two：When base station reaches given threshold according to the bandwidth for confirming any one section of circuit of result judgement, this is determined
Congestion will not occur for one section of circuit of meaning, can be as UE access or the objective network of switching.
In the embodiment of the present invention, base station is except needing to refer to the quality such as the characterization Congestion Level SPCC carried in loop state information
Outside the information of aspect, it is also necessary to the bandwidth of reference loop.The bandwidth in circuit is just solid when operator carries out network deployment
Decide, the network node at circuit both ends can be known.When the bandwidth in circuit reaches a certain level, such as, gigabit or ten thousand
Million, then base station can consider the problem of this section of circuit is not in terms of transmission, i.e., congestion will not occur, so that also without right
Loop mass is monitored.
Certainly, base station can consider the bandwidth in circuit, and circuit link-quality, and e.g., base station can be with prioritizing selection
The bandwidth in circuit is high, and the low network of Congestion Level SPCC provides service for UE.
Mode three：Except the factor considered in preceding embodiment, base station can also select the mesh of access or switching for UE
When marking network, with reference to default ANDSF strategies.Under the prior art, ANDSF strategies are transparent, base station for base station
It is not aware that what the corresponding ANDSF strategies of a UE are.Base station can obtain its corresponding ANDSF plan from core network requests
Slightly, it can also allow UE that its corresponding ANDSF strategy is reported to base station.
Thus, base station can use following strategy：When each circuit at least two networks to be selected each corresponds to
Ethernet bandwidth, use duplex mode, propagation delay time or/and buffering area seizure condition and quality of eating dishes without rice or wine in, each parameter
It is satisfied by use demand or each parameter is unsatisfactory for only partial parameters in use demand or each network to be selected and meets to use
During demand, base station determines the objective network of UE access or switching according to the priority of default ANDSF policy developments.Change speech
It, is when that can not judge that the loop performance in any network to be selected is more excellent according to the loop state information in each circuit, base station ginseng
Default ANDSF strategies are examined, select suitable objective network.
Further, in the embodiment of the present invention, if the network node that UE can be accessed is a relay network node, that
It is also required to consider loop state information between the relay network node and its host base station, aerial quality information etc., can
Can be the current measurement amount defined in 36.314 specifications to provide the measurement of correlation for being used for referring to.
Base station and UE can be caused to obtain the situation of network loop, aid in it to carry out more preferable network selection and switching
Judgement, so as to provide more preferable service for UE, and can balance the load of different access networks.
Certainly, only it is introduced in the various embodiments described above exemplified by accessing control node and being base station, if access control node
It is RNC, then can be equally applicable in, details are not described herein.
