For this reason, the present invention proposes a solution, can the coexistence mechanism of effective coordination LTE+WiFi, ensures the experience of user while saving flow.
First, LTE+WiFi integration technology is introduced.
LTE-U is through high pass and other wireless access networks (radioaccessnetwork is called for short RAN)) popularization of supplier, LTE-U is a kind of mode directly running LTE in 5GHz unauthorized frequency range.This mode is in order to obtain more wireless frequency spectrum to support Information Mobile Service, and in coverage, advantage can reduce.LTE-U can easily and the WiFi of unauthorized frequency range coexist and ensure that it runs, this is similar from the method for present different WiFi network shared band.
LTE+WiFi link aggregation (LWA) is the technology that high pass is widelyd popularize, and by LWA, separable LTE data payload, some flows can be transmitted by WiFi, remaining, are transmitted by LTE itself, thus greatly promote the performance of LTE service.Adopt LWA, WiFi to run in unauthorized frequency range, and LTE runs in mandate frequency range, the combination of these two kinds of wireless technologys can bring excellent Consumer's Experience.LWA only needs simple software upgrading just can enable, and smart mobile phone adopts LWA just can power for these two kinds of wireless networks and split data plane traffic, thus makes a part of LTE flow can carry out tunnel transmission by WiFi, and residual flow is by LTE self-operating.At the flow flowing through WiFi that WiFi access point is collected, LTE small cell base station can be transferred back to immediately, can effectively grappling session.These flows combine in LTE small cell base station, are then sent to mobile packet-based core networks (evolvedpacketcore is called for short EPC), and are sent to the Internet therefrom.
Usually, by exempt from licensed band be polymerized to license carrier wave mainly contain three kinds in the mode of hoist capacity, wherein first two is more common.One is supplementary downlink mode (SDL), namely exempts from licensed band and is only used to do downlink transmission; Two is carrier aggregation mode (CA), namely allows to exempt from licensed band for down link and up link, and as typical LTE TDD system, its most critical advantage is exactly flexible exempts from licensed band resource amount for uplink and downlink link.In SDL and CA pattern, exempt from licensed band all only for data Layer, all key-course flows are all by licensed band process, and operator controls permitting and exempting from licensed band resource simultaneously.The main LTE-U proponent of current 3GPP in SDL pattern, because it can realize simplified deployment and operation concerning operator, reduces the complexity of equipment to deployment scenario multi-focus simultaneously.Also have the third pattern to be called stand-alone mode (SA), namely exempting from licensed band independent operating LTE and non-usage license frequency range.
Operator uses a crucial motivation of LTE+WiFi convergence strategy to be help them under single wireless electricity access technology, obtain more usable spectrum.At present, part mobile operator is just using WiFi network relieving flowing volume to alleviate the burden of cellular mobile network, by being combined license and exempting from licensed band under a technology (LTE), operator expects to manage by simplified network, making LTE network infrastructure and network management and security capabilities obtain tighter integration, obtaining the control to exempting from licensed band simultaneously.In addition, permit and exempt from radiotechnics single in licensed band and be also conducive to better controlling Consumer's Experience.
Particularly, as shown in Figure 3, first embodiment of the invention proposes a kind of wireless network intelligent control device, comprising: monitoring modular 201 and control module 202, wherein:
Monitoring modular 201, for available LTE and WiFi signal in environment residing for monitoring terminal equipment;

Further, described monitoring modular 201, if be not also connected to LTE or WiFi channel for described terminal equipment, then judge whether described LTE or WiFi channel recovers upstate, specifically comprises by periodic heartbeat mechanism: described terminal equipment sends heartbeat message every one-period to the webserver; If in designated period, receive at described LTE or WiFi channel the heartbeat return information that described server returns, then judge that LTE or WiFi channel is in upstate, otherwise, judge that LTE or WiFi channel is in down state; And if described terminal equipment has been connected to LTE or WiFi channel and carries out access to netwoks, then carried out the inspection of network state by ConnectivityManager, there is available LTE or WiFi signal to judge that whether LTE or WiFi channel is corresponding.
Further, described control module 202, also for there is available LTE and WiFi signal in described environment simultaneously:
If active user uses non-payment WiFi and common LTE network, and WiFi signal strength and stability sexual satisfaction user current state is to the demand of network, then connected mode is now maintained by WiFi and connects;
If active user uses non-payment WiFi and common LTE network, but WiFi signal intensity or stability cannot meet the demand of user's current state to network, then connected mode is now LTE+WiFi binary channels, and data traffic is main channel with WiFi, take LTE as secondary channels;
If active user uses paying WiFi and common LTE network, then connected mode is now LTE+WiFi binary channels, and calculated flow rate consumption is by the flow cost of LTE and WiFi channel, select wherein lower-cost channel as main channel.
Further, described control module 202, if also to comprise network demand for user's current state, video is this requires high down load, then adopt supplementary downlink mode WiFi to be exempted from licensed band to be only used to do downlink transmission, and other additional uplink network demands are loaded to LTE channel.
Particularly, when whether there is available LTE and WiFi signal in environment residing for monitoring terminal equipment, specifically following scheme can be adopted:
1, for mobile phone, if mobile phone does not connect certain channel (LTE or WiFi), then judge whether this channel recovers upstate by periodic heartbeat mechanism.
Wherein, heartbeat mechanism refers to reception in network and sends data is all use the SOCKET in operating system to realize.If but this socket disconnects, time that sends data and receives data, just necessarily have problem.In order to judge whether this socket can also use, just need to create heartbeat mechanism in systems in which.Heartbeat mechanism is achieved in TCP.If be provided with heartbeat, that TCP will send the heartbeat (such as 2 times) of the number of times of setting within the regular hour, and this information can not affect the agreement of definition.So-called " heartbeat " is exactly timed sending self-defining structure (heartbeat packet or heartbeat frame), allows the other side know oneself " online ", to guarantee the validity linked.
In the heartbeat mechanism of TCP, system default arranges the palmic rate of 2 hours; Current Google is in android system, and in 2g/3g network center, hop cycle acquiescence is 28 minutes; The heart beat cycle of micro-letter acquiescence is then 5 minutes; The heart beat cycle of QQ acquiescence is then 3 minutes.
If mobile phone does not connect certain channel (LTE or WiFi), then judge whether this channel recovers upstate, is implemented as follows by periodic heartbeat mechanism:
Set up one group of heartbeat packet for the channel do not connected respectively, heart beat cycle can be arranged according to actual conditions, (being such as set to 5 minutes);
Every one-period, mobile phone terminal sends fixing heartbeat message to server, and service end receives the fixing heartbeat return information of rear reply one.If client does not receive return information at certain channel in designated period, then can think that now this channel is down state; Otherwise this channel is in upstate.Such as, if mobile phone terminal does not receive the return information of LTE channel, then this channel is in down state; Otherwise, then upstate is in.
If 2 have connected certain channel (WiFi or LTE) carry out access to netwoks, then carried out the inspection of network state by ConnectivityManager, there is available LTE or WiFi signal to judge that whether LTE or WiFi channel is corresponding.ConnectivityManager can complete following four main tasks:
A) cell phone network state (comprising GPRS, WIFI, UMTS etc.) is monitored;
B), when mobile phone state changes, broadcast is sent;
C) failover is carried out when a network connection failure;
D) for application program provides the high accuracy and coarse state that can obtain available network.
When monitoring network connection state and changing, then intelligence changes optimum internetwork connection mode; Equally can where necessary to be supplied to user reminding, such as, when user sees video, WiFi signal disconnects, and whether prompting user continues to use LTE network viewing.
When there is available LTE and WiFi signal in environment residing for terminal equipment simultaneously, user's use scenes of institute's foundation judges according to following aspect: the network condition that equipment is current, the current residing interface of equipment, the current open function of equipment is to the demand of network.
Particularly, for example, following condition is included but not limited to according to the condition of user's scene intelligent switching signal passage:
1) if active user uses non-payment WiFi and common LTE network (namely by flow charging), and WiFi signal strength and stability sexual satisfaction user current state is to the demand of network, then connected mode is now maintained by WiFi and connects.Such as in free WiFi, user only opens the IM such as micro-letter, the QQ IM service lower to network demand degree, then network by WiFi passage.
2) if active user uses non-payment WiFi and common LTE network, but WiFi signal intensity or stability cannot meet the demand of user's current state to network, then connected mode is now LTE+WiFi binary channels, and data traffic take WiFi as main channel, is auxiliary with LTE.
Such as, in free WiFi, user is seeing the very high demand that has to network such as video, now then needs LTE+WiFi two-channel networked, and makes flow by free WiFi passage uplink and downlink as far as possible; For seeing this user's request requiring high down load of video, a kind of possible implementation adopts supplementary downlink mode (SDL) WiFi to be exempted from licensed band to be only used to do downlink transmission, thus ensure that video-see; And other additional uplink network demands are loaded to LTE path, reduce the consumption of flow.
Applicating example:
In free WiFi, user opens other functions less to network traffic demand such as function and micro-letter/QQ seeing that video etc. is very large to traffic demand, now merely rely on WiFi network to be difficult to meet user's smoothness simultaneously and see video and the demand keeping exchanging with the external world, then can pass through LTE+WiFi two-channel networked, and make the function of large discharge by free WiFi passage uplink and downlink as far as possible.Wherein, a kind of possible implementation is, requiring that the function of high down load adopts supplementary downlink mode (SDL), WiFi being exempted from licensed band and being used to do downlink transmission, thus ensure that video-see for seeing that video is this; And other functions less to network traffic demand are loaded to LTE path, reduce the consumption of flow.
3) if active user uses paying WiFi (such as, by the period and press flow) and common LTE network, then connected mode is now LTE+WiFi binary channels, and calculated flow rate consumption is by the flow cost of LTE and WiFi frequency range, alternative costs lower as main channel.
Such as, if the WiFi that user uses is by traffic consumes charging, then at the cost calculating WiFi and LTE unit discharge respectively, selection unit's flow cost lower as main signal channel;
And for example, if the WiFi that user uses is by connecting duration based accounting, then allow signal for WiFi channel main channel (because the traffic consumes of now WiFi consumed flow cost and generation has nothing to do) in the connect hours at WiFi.
In addition, if only there is available WiFi signal in described environment, then control terminal connects online by WiFi signal; If only there is available LTE signal in described environment, then control terminal connects online by LTE signal.
