Background technology
Along with the development of 4G network, people more and more experience conventional communication mode can not meet the current business demand exponentially increased of people.Wireless mobile communications of future generation will develop into the fusion of multiple wireless access technology, and as WLAN, WiMAX and 5G cellular network etc., this makes its topological structure progressively evolution will become the dimensional network structure of heterogeneous, eclipsed form, i.e. heterogeneous network.Same ground can simultaneously by multiple network coverage, and heterogeneous networks can provide different performances.On the other hand, along with the rise of small-cell network (as Micro, Pico, Femto), in communication process, user is easy all the more from a cell merge to another community, therefore need the continuity ensureing user communication business, good Consumer's Experience is provided.
How to provide seamless service to user and to reduce expense in the network of isomery small-cell is problem very important in wireless mobile communications always.Owing to there are differences between isomery small-cell, and because of factors such as the different demand of varied, the user of business and environment impacts in various degree, the user under this heterogeneous network is switched more complicated than the switching of consolidated network many.And along with the increase of number of mobile users, the switching problem of this type of complexity is more urgently to be resolved hurrily.
Existing handover scheme pays close attention to unique user, provides switch the mechanism of preparation to the switching problem of unique user, and utilizes minizone to cooperate in groups, jointly for user provides service, compares traditional handover scheme and decreases handover delay and signaling consumption.
But such scheme does not solve the problem that multiple user switches together.If multiple user same time all need move to next same cells from current area in small-cell, according to scheme in the past, PAR and NAR can process repeatedly to the handover request of each UE, can produce a large amount of exchange message, increase switching times, cause bandwidth waste.And based on multiple users of identical services characteristic type when switching, PAR/NAR can adopt identical processing mode (as distributed comparable bandwidths etc.) to business of the same race, can reduce the generation of control signal, improves user QOS.
In addition, also do not have a kind of changing method at present for following 5G isomery small-cell multi-user, therefore inventor is according to the development of the mobile broadband wireless communication technology and evolution, proposes the multi-user's changing method based on service feature in a kind of prospective 5G network.

2) if adjacent UEs has switching purpose after receiving message in same community, just the service feature type that self is current is identified, and compared with the service feature type used with initial UE, that same class then adds information to initial UE transmission switching and carries out switching preparation, difference is then abandoned performing switching together, if do not switch purpose, directly ignore the handover information of initial UE;
3) what initial UE received that adjacent UEs sends adds information, is classified as one group, then sends the handover informations such as group member quantity to PAR;
4) the access route (newaccessrouter, NAR) of PAR available cell network towards periphery sends switching command, after NAR determines own net state, returns the optional priority of Target cell weight to PAR;
5) initial UE switches after confirmation through PAR, and group member is performed switching to Target cell together.
Further, in the method, all UE are the multi-mode mobile user equipment that can be operated in heterogeneous networks, include and receive handover information and service feature type, send and add handover request, service feature identification entity.
Further, the network state described in this method comprises the guarantees of RST (RSRP/RSRQ), loading condition and business QOS performance (comprising bandwidth, time delay, shake, packet loss etc.); Described service feature type comprises: conversation class, Streaming Media class, interactive class and background classes.

Further, PAR or NAR described in this method comprises: timing is monitored own net state; By monitor obtain RST, network load condition, the business QOS performance index that can provide stored in specified list, as the input of Fuzzy AHP; Periodically upgrade the parameter in existing list, wherein the update cycle is chosen to be 1 hour.
Further, described service feature identification entity comprises with lower module: trigger module, judge module, Executive Module;
The function of described trigger module mainly, according to the initial UE handover preparation information received, triggers the service feature type identifying and self using, and is sent to judge module, as the foundation judged;
Described judge module realizes own service type and initial UE to broadcast compared with the service feature type that sends, obtains a result;
Described Executive Module according to judged result, will determine whether this UE needs to add the switching set-up procedure of initial UE.
Further, described trigger module identifies own service characteristic type on the basis of self DPI unit.
Further, described DPI unit, according to current transmission business record, obtains user URL, judges the service feature classification belonging to user URL.
Further, also comprise in the method: when one group of n UE successful switch is to certain Target cell, by the Target cell weight decline n*w% selected, previous place cell weight then rises n*w%; 1 UE can only be supported when a subzone network accumulated weight lower than certain lower threshold (namely now load is larger) or current area network but can not support that multiple UEs completes switching, what this community can not become UEs can candidate cell, until in this subzone network some UE business end of transmission or when being switched to other communities, again participate in the candidate of Target cell.
