Business migration method and device

Technical field

The present invention relates to the communications field, in particular to a kind of business migration method and device.

Background technology

Along with wireless communication technology and the continuous evolution of standard, mobile Packet Service has obtained huge development, single The data throughput capabilities of terminal is constantly promoting.With Long Term Evolution (Long Term Evolution, referred to as LTE) As a example by system, can support that in 20M bandwidth the data of descending maximum rate 100Mbps are transmitted, follow-up In LTE (LTE Advanced) system strengthened, the transfer rate of data will promote further, it might even be possible to Reach 1Gbps.

The growth of terminal data portfolio expansion type, makes existing Internet resources the most unable to do what one wishes, especially exists In the case of a new generation's communication technology (such as 3G, LTE) also cannot extensively arrange net, the thing followed is to use Family speed and traffic demand cannot meet, the variation of Consumer's Experience.How preventing and changing this situation is operation The problem that business must take into, on the one hand needs to accelerate popularization and the network design of new technique；On the other hand, it is desirable to Can be by existing network and technology be strengthened, to reach the purpose of fast lifting network performance.Many institute's weeks Knowing, in third generation partner program, (The 3rd Generation Partnership Project is referred to as Outside radio network technique 3GPP) provided, the most commonly used WLAN (Wireless Local Area Network, referred to as WLAN), it is based especially on Institute of Electrical and Electronics Engineers (Institute Of Electrical and Electronics Engineers, referred to as IEEE) 802.11 standards WLAN Through being widely used in focus access covering in family, enterprise even the Internet.Wherein by WiFi alliance The technical specification that (Wi-Fi Alliance) proposes is most widely used, therefore in reality WiFi network often follow based on The wlan network of IEEE 802.11 standard is equivalent to, and in the case of not causing and obscuring, following is also adopted by WiFi module describes wireless receiving and dispatching and the processing module supporting WLAN in network node.

Under this premise, some operators and company have been proposed that enters WLAN with existing 3GPP network Row merges, it is achieved joint transmission, to reach load shunting and to improve the purpose of network performance.3GPP SA2 leads to Cross access network discovery and selected functional unit (Access Network Discovery and Selection Functions, referred to as ANDSF) scheme, it is provided that a kind of is that terminal selects target according to carrier policy The pattern of access network.

3GPP R10 defines ANDSF standard, and ANDSF realizes Intelligent network-selecting as accessing anchor point, logical Cross network to work in coordination with the mutual of terminal, it is achieved effective shunting of network insertion, meet the operation of following multi-network cooperative Direction.ANDSF generates strategy based on information such as network load, terminal capability, user's signing situations, helps Terminal use selects the network formats most preferably accessed, it is achieved the collaborative operation of plurality of access modes.ANDSF was both Can individually dispose, it is possible to close with other network element and set.At present, industry Main Viewpoints thinks that ANDSF can portion Administration is in policy control and charging (Policy Control and Charging, referred to as PCC) equipment.
