For ease of description, the embodiment of the present invention is only introduced by taking LTE as an example, and correspondingly, the shunting decision element is For the enode b in LTE, core network element refers to the packet data gateway that shunting attribute information is carried for generating, but originally Art personnel should be appreciated that the protection domain of technical scheme is not limited to LTE system, and core net net Member is also likely to be that other can generate the core net part of carrying shunting attribute information.

The embodiment of the present invention provides a kind of method of network control shunting, including：

In order to ensure the service quality of business, the concept of carrying is introduced in cordless communication network technology.Carrying is one The concept of individual virtual route, multiple carryings can be established between terminal and network, each corresponding a set of QoS parameter of carrying, Such as time delay, shake, there is the business of same or like QoS parameter to be placed in same carrying and transmit.Different holds Load can be made a distinction by carrying mark.Generally, the corresponding one or more traffic flow template of each carrying（Traffic flow Temple, TFT）, traffic flow template can be divided into uplink service flow template and downlink business flow template, and traffic flow template includes The IP five-tuple information of the above-mentioned business with same or like QoS parameter, traffic flow template are established or changed in carrying During there is core net to issue business respectively is placed on into corresponding carrying according to traffic flow template filter traffic to terminal, terminal On be transmitted.The attribute of carrying is primarily referred to as whether the carrying can shunt, described be carried in embodiments of the present invention Priority and the carrying during shunting can be transmitted by which kind of routed path.

In the prior art, when terminal, which switches to WLAN, carries out service distributing, generally by terminal itself The distributing strategy of setting switches over, or the distributing strategy that terminal issues according to network side switches over；If pass through The distributing strategy that terminal itself is set switches over, and due to end side not knowing about to the Internet Use of network side, causes The distributing strategy of terminal has larger randomness, and shunting result can be caused uncontrollable；And if issuing shunting plan using network side Slightly to the method for terminal, the shunting effect that can cause to be brought according to the time variation or diversity of wireless environment again is lifted limited Problem.Therefore, the embodiment of the present invention provides a kind of method of network control shunting, and the carrying carried according to end side shunts attribute Information, other shunting relevant informations obtained with reference to the enode b in LTE, makes shunting decision-making, that is, carries handover decisions, Again by carrying handover decisions order, the terminal is carried out carrying switching, the carrying for needing to be transferred to WLAN is switched To WAP, corresponding traffic flow template is mapped to WLAN, passes through the WLAN transport module of terminal Carry out the transmission of corresponding business.Method described in the embodiment of the present invention, due to introducing carrying shunting attribute information, make network-side It is not that carrying handover decisions are carried out according to the network state of simple access network, such as the load of access network and link of eating dishes without rice or wine, and It is that the attribute of itself makes decisions with reference to carrying, makes the carrying switching of terminal more rationally efficient, Cellular Networks can be made effectively auxiliary Help or control terminal to access suitable WAP, improve Consumer's Experience.Terminal described in the embodiment of the present invention refers to prop up Hold access Cellular Networks and WLAN terminal device.

Switching command is carried described in the embodiment of the present invention includes carrying mark, and the carrying mark includes：Radio bearer mark Know and/or grouping system carrying identifies.In embodiments of the present invention, when enode b controls the terminal to carry out carrying switching When, the carrying mark of the carrying handover information of transmission needs to include following at least one：Radio bearer identification（Radio Bearer ID）, evolved packet system carrying mark（EPS Bearer ID）；Wherein, evolved packet system carrying mark is the packet system One kind of system carrying mark,, can in other cellular network systems using evolved packet system carrying mark in LTE system To take grouping system carrying mark corresponding with cellular-specific net system, make carrying switching command can in corresponding Cellular Networks Distinguish to be switched carrying；Radio bearer identification, evolved packet system carrying mark are used for that Division identification to be to be switched holds Carry, the carrying switching command is accurately acted in respective carrier.

Specifically, the method described in the embodiment of the present invention, the carrying shunting attribute information include following at least one：

Wherein, the core net path refers to the information transmission path by Cellular Networks；The local forward-path refers to The information transmission path being directly connected without Cellular Networks with internet.

Determine that information, carrying shunting class information, routing characteristic information can effectively really by above-mentioned carrying shunting Whether the attribute carried surely, such as the carrying can shunt, priority when being carried on shunting, and the carrying can To be transmitted by which kind of routed path.

Specifically, the method described in the embodiment of the present invention, the shunting decision element shunt attribute letter according to the carrying The specific steps of breath generation carrying switching command include：

Because the WAP having can access the core net of above-mentioned cellular network system, some WAPs can be straight Be connected to internet in succession, therefore WAP routing configuration information can be obtained, if WAP have access to it is above-mentioned The core net of cellular network system, then the routing configuration information of WAP be set to the information in core net path；If wirelessly connect Access point is directly connected to internet, then the routing configuration information of the WAP is set to the information of local forward-path.

When the shunting decision element shunts attribute information generation carrying switching command according to above-mentioned carrying, it is divided into following three Kind situation：

Situation one, determination information is shunted for carrying, if carrying shunting determines that information is to allow the information of carrying shunting, Decision element is then shunted to shunt carrying；

Situation two, class information is shunted for carrying, shunting decision element is held according to what carrying shunting class information included The order of shunting switching is carried, carrying is shunted；Or shunting decision element sends the carrying shunting class information to nothing Line access point, WAP are judged according to the network condition of itself, if the network load weight of WAP, network Information on load is less than default threshold value, then WAP shunts class information according to the carrying, and only high to priority holds Carry and confirm to receive simultaneously feeding back confirmation message, avoid aggravating the burden of WAP, influence Consumer's Experience；If WAP Network load it is excessively heavy, network load information be less than default Second Threshold, then WAP is not to any carrying confirmation Receive, avoid influenceing Consumer's Experience；

Situation three, for carry routing characteristic information, shunting decision element need obtain WAP routing configuration Information, then in conjunction with carrying routing characteristic information generation carrying switching command；

Or shunting decision element sends carrying routing characteristic information to WAP, WAP and combines itself Routing configuration information, confirm the carrying that can receive, and send an acknowledgement message to the shunting decision element, the shunting is determined Plan network element generates carrying switching command further according to the confirmation message；

Or terminal sends carrying routing characteristic information to WAP, the WAP and combines the road of itself By configuration information, the carrying that can be received being confirmed, and sending an acknowledgement message to the terminal, the terminal is further according to the confirmation Message carries out carrying switching, and to the shunting decision element feedback carrying handoff completion message, informs that shunting decision element is held Carry switch instances；Wherein, if the carrying routing characteristic information comes from core net and surveyed, it is necessary to which shunting decision element sends institute Carrying routing characteristic information is stated to terminal；If carrying routing characteristic information to be generated by terminal oneself, decision-making need not be shunted Network element sends the carrying routing characteristic information to terminal.

Wherein, the routing configuration information of itself is combined according to carrying routing characteristic information in WAP to confirm to connect During the carrying of receipts, if the routing configuration of WAP is core net path, for core net path or local forwarding The carrying in path, WAP can confirm to switch over the carrying, and send confirmation message；If WAP Routing configuration be local forward-path, then carrying that can only be to local forward-path confirms to switch over, and sends confirmation and disappear Breath；The routing configuration of WAP is represented by routing configuration information, and the routed path of carrying is route by carrying What characteristic information represented；

The routing configuration information that decision element obtains WAP is shunted, then in conjunction with carrying routing characteristic information generation The criterion for carrying the criterion of switching command and the confirmation reception carrying of WAP is identical.

Specifically, the method described in the embodiment of the present invention, the shunting decision element is according to the carrying routing characteristic letter The step of routing configuration information generation carrying switching command of breath combining wireless access point, specifically includes：

Alternatively, the method described in the embodiment of the present invention, the shunting decision element shunt attribute letter according to the carrying The specific steps of breath generation carrying switching command also include：

Wherein, the WAP is shunted class information according to the carrying and combine the network state information of itself, Confirm the carrying that can be received, and the specific steps of feeding back confirmation message include：The network state information includes network load Information, it is preferential when the WAP is split according to carrying when the network load information is less than default threshold value Level confirms the high carrying of reception priority, wherein, the network state information can also can reflect including others wirelessly to be connect The information of the network condition of access point, then further according to this category information, confirm to connect with reference to the carrying shunting class information of carrying The carrying of receipts；The network condition of the WAP is represented that the load condition in network condition is by net by network state information Network information on load represents；

The WAP is combined the routing configuration information of itself according to the carrying routing characteristic information, confirm energy The carrying enough received, and the specific steps of feeding back confirmation message include：When the routing configuration information of the WAP is core During the information in heart networking footpath, or, when the routing configuration information of the WAP and the carrying routing characteristic information all When being the information of local forward-path, the WAP confirms to receive the carrying；

Wherein, the shunting decision element, which sends carrying shunting attribute information to the WAP, can following two Kind mode：

Shunting decision element sends the carrying shunting attribute information to WAP by core net；

Shunting decision element directly transmits the carrying shunting attribute information to WAP；

Correspondingly, the WAP also has two ways to the shunting decision element feeding back confirmation message：
