Example a 1:The quality (terminal works are on a certain carrier wave) of the signal of source base station well, for example is higher than preset letter Number quality threshold, i.e., the service performance that terminal is obtained in source base station is good, but in the switching in frequency priority, such as eventually The standard at end define be operated in some frequency range it is more energy efficient/efficiently, alien frequencies (same slice example difference carrier wave) may be triggered It measures and switches.

Example a 2:The quality (terminal works are on a certain carrier wave) of the signal of source base station is bad, for example is less than preset letter Number quality threshold, i.e., the service performance that terminal is obtained in source base station is bad, but in the switching in frequency priority, such as eventually The standard at end define be operated in some frequency range it is more energy efficient/efficiently, alien frequencies (same slice example difference carrier wave) may be triggered It measures and switches.

Example a 3:The quality (terminal works are on a certain carrier wave) of the signal of source base station is bad, for example is less than preset letter Number quality threshold, i.e., the service performance that terminal is obtained in source base station is bad, if but the quality of the signal of adjacent base station (terminal works exist On a certain carrier wave) it is higher than preset signal quality thresholding, it is determined that and terminal need to switch over.

Example a 4:When the signal quality (same slice example difference carrier wave) of adjacent base station is higher than certain thresholding, source base station touches Hair switching (to same slice example difference carrier wave) request, that is, determine that terminal need to switch over.

Example a 5, when the signal quality of source base station is less than certain thresholding, while signal quality (the same slice reality of adjacent base station The different carrier waves of example) it is higher than certain thresholding, source base station triggering switching (to same slice example difference carrier wave) request determines eventually End need to switch over.

Example a 6, when the signal quality (identical services type, identical services credit rating) of different system adjacent base station is higher than one Determine thresholding, source base station triggering switching (to different system with type of service same trade business credit rating) request determines that terminal needs to carry out Switching determines that terminal need to switch over.In the example, with enhanced mobile Internet (eMBB, Enhance Mobile Broadband, eMBB) network slice talk business for, LTE can regard another as different system for 5G networks Network of throwing the net is sliced.

Example a 7, the signal quality of source base station are less than certain thresholding, and the signal quality (identical services of different system adjacent base station Type, identical services credit rating) it is higher than certain thresholding, source base station triggering switching is (to different system with type of service same trade business matter Measure grade) request, that is, determine that terminal need to switch over.

It can be seen that through the above, base station can determine whether terminal needs by a variety of arbitration schemes in the embodiment of the present application Switch, there are mainly two types of situations in short, consider that signal quality is preferential and frequency is preferential respectively, preferential in signal quality In the case of, if the signal quality of adjacent base station is higher than source base station, it is determined that terminal needs switch over.In the preferential situation of frequency Under, if the signal quality of adjacent base station is less than source base station, still start different-frequency measure.

Which kind of no matter measured using judgement in the embodiment of the present application, if judge that terminal needs switching, one in M adjacent base station Surely there is N number of quasi- target BS;The quasi- target BS of each of N number of quasi- target BS meets condition:Terminal accesses quasi- target base It stands more excellent than the service performance that access Current Serving BTS obtains.It for example, can will be adjacent in the case where signal quality is preferential Signal quality is higher than target BS subject to the adjacent base station determination of source base station in base station.It, can be by demand in the case where frequency is preferential The special frequency channel that is operated in of network slice example on adjacent base station determine subject to target BS.

The embodiment of the present application finds the standard of the information matches of network slice example corresponding with terminal from quasi- target BS Target BS, if there is no the quasi- targets of the information matches of the information of network slice example network slice example corresponding with terminal Base station then needs to carry out reconfiguring for network slice example, and optionally scheme is one kind, from service performance more preferably adjacent base station A base station is found out as target BS;The embodiment of the present application also provides other embodiments, is further explained below.

Optionally, there are N number of quasi- target BS in M adjacent base station;The quasi- target BS of each of N number of quasi- target BS is full Sufficient condition:It is more excellent than the service performance that access Current Serving BTS obtains that terminal accesses quasi- target BS;N is just no more than M Integer.Source base station is sliced the information of example according to the network of the signal quality of M adjacent base station, M adjacent base station and terminal-pair is answered Network slice example information, the target BS that terminal need to switch is determined from M adjacent base station, including:If net is not present Network is sliced the quasi- target BS of the information matches of the information network slice example corresponding with terminal of example, then:For N number of quasi- mesh The quasi- target BS in each of base station is marked, is determined from the information that the network that quasi- target BS includes is sliced example:With terminal The information and the highest network of similarity of the highest network slice example of similarity of the information of corresponding network slice example It is sliced the similarity of the information of the information network slice example corresponding with terminal of example;It is corresponding according to each quasi- target BS Similarity determines the target BS that terminal need to switch from N number of quasi- target BS;Wherein, the network slice of quasi- target BS The similarity of the information of the information of example network slice example corresponding with terminal is that the letter of example is sliced according to two networks What the parameter type and parameter value of the parameter for the network slice example that breath includes determined.In this way, when there is no network slice is real When the quasi- target BS of the information matches of the information network slice example corresponding with terminal of example, similarity can be selected highest Network slice example is reconfigured, in this way, the parameter item that the reconfiguration course of network slice example is changed is as far as possible It is few, and the mobility scale of the value of parameter is also small as far as possible, can further accelerate to reconfigure rate.

For example, when determining that terminal needs to switch over, according to the signal quality of M adjacent base station, the net of M adjacent base station Network is sliced the information of example and the information of the corresponding network slice example of terminal, determines that terminal need to be cut from M adjacent base station The target BS changed.For example service performance more preferably quasi- target BS can be first filtered out, if there is no network slice examples The quasi- target BS of the information matches of information corresponding with terminal network slice example, then find out on each quasi- target BS with end Hold the information of the highest network slice example of the information similarity of corresponding network slice example.Alternatively, determine terminal need into It can first determine whether that the information network corresponding with terminal that example is sliced there are network is sliced the information of example when row switching The adjacent base station matched, and if it exists, then by target BS subject to service performance in these adjacent base stations more preferably adjacent base station determination.

There are many schemes that similarity is calculated in the embodiment of the present application, for example determines that two networks slice to be calculated is real Parameter type in the parameter for the network slice example that example includes, for example, each layer includes in Fig. 2 b module type, Such as in Fig. 2 b network slice example 211 in PDCP layer include three modules, and network be sliced example 212 in PDCP layers include One module;Also need to the ginseng in the parameter for the network slice example for determining that two networks slice example to be calculated includes PHY layer TTI is 1ms in network slice example 211 in numerical value, such as Fig. 2 b, and the PHY layer TTI in network slice example 212 is 0.5ms.The parameter type that two networks are sliced to the parameter that the network that example includes is sliced example is compared, and looks to differ How many a parameter types, then the parameter value of each parameter type is compared, look to differ, by these there are the item of difference into The similarity of two network slice examples is determined in the calculating such as row weighting summation.Such as in Fig. 2 b, by comparing, network is cut Similarity between piece example 211 and network slice example 213 be more than network slice example 211 and network slice example 212 it Between similarity.

According to each corresponding similarity of quasi- target BS in the embodiment of the present invention, determined from N number of quasi- target BS The target BS that terminal need to switch, there are many schemes, such as Fig. 2 e to provide a kind of side of the selection target base station based on Fig. 2 d Method flow diagram realizes the step 226 for determining target BS using following methods flow as shown in Figure 2 e:

Step 251, source base station sends network to quasi- target BS and is sliced example reconfiguration request;

Step 252, quasi- target BS is after performing network slice example and reconfiguring, and in two kinds of situation, the first is matched The case where the case where being set to work(can be sliced example to source base station feedback network and reconfigure success response, second of configuration failure, can To the slice example reconfiguration failure response of source base station feedback network, or any information is not fed back, source base station is in preset duration Response message is not received, that is, judges reconfiguration failure;

Step 253, source base station can be sliced from network is received in several quasi- target BS that example reconfigures success response Determine target BS.

Optionally, above method step is applicable to Xn interfaces, according to NGx interfaces, then source base station and quasi- target BS Between communication can pass through MME transparent transmissions.Fig. 2 f provide a kind of method flow schematic diagram of the selection target base station based on Fig. 2 d, As shown in figure 2f, the step 226 for determining target BS is realized using following methods flow:

Step 261, source base station sends network to MME and is sliced example reconfiguration request;

Step 262, MME is sliced example reconfiguration request to quasi- target BS transparent transmission network;

Step 263, quasi- target BS is after performing network slice example and reconfiguring, and in two kinds of situation, the first is matched The case where the case where being set to work(can be sliced example to MME feedback networks and reconfigure success response, second of configuration failure, can be to MME feedback networks are sliced the response of example reconfiguration failure, or do not feed back any information;

Step 264, if the response message that MME is received, the network received slice example is reconfigured into success response Or network slice example reconfiguration failure response passes through source base station;

Step 253, source base station can be sliced from network is received in several quasi- target BS that example reconfigures success response It determines target BS, in another case, source base station does not receive response message in preset duration, that is, judges to reconfigure mistake It loses.

Efficiency is reconfigured in order to improve, optionally, according to the corresponding similarity of each quasi- target BS, from N number of quasi- target The target BS that terminal need to switch is determined in base station, including:It will be in N number of quasi- target BS:The highest quasi- target base of similarity Station is determined as target BS;According to the corresponding similarity of each quasi- target BS, determine that terminal is needed from N number of quasi- target BS After the target BS of switching, further include:Into N number of quasi- target BS, the highest quasi- target BS of similarity sends network slice Example reconfiguration request;Wherein, network slice example reconfiguration request includes the information of the corresponding network slice example of terminal; If it is determined that network be sliced example reconfiguration failure, then into N number of quasi- target BS except be transmitted across network slice example reconfigure In quasi- target BS except the quasi- target BS of request:The highest quasi- target BS of similarity sends network slice example and re-matches Request is set, until receiving network slice example reconfigures success response;The network received slice example is reconfigured into success It responds corresponding quasi- target BS and is redefined as target BS;Wherein, network slice example reconfiguration request is for making reception The network slice example that the quasi- target BS that example reconfiguration request is sliced to the network includes to itself carries out reconfiguration operation, So that the information of the corresponding network slice example of network slice example compatible terminal after reconfiguring.Similarity can be selected by reconfiguring Highest network is sliced example operation, can improve the rate reconfigured, such as the size of TTI is adjusted from 1ms to 0.9ms, This action is for the eating dishes without rice or wine of base station, and in the case where hardware environment is supported, this is repairing on a software parameters configure Change, very fast, the time can be ignored.

There are three quasi- target BS, are ranked up according to similarity, quasi- target BS 1 and end It is highest to hold the similarity of the information of corresponding network slice example, and quasi- target BS 2 takes second place, and quasi- target BS 3 is minimum.Source Base station sends network to quasi- target BS 1 and is sliced example reconfiguration request, so that quasi- target BS 1 will be corresponding with terminal thereon The highest network slice example of information similarity of network slice example is reconfigured.If it is determined that network slice example re-matches It sets unsuccessfully, for example receives network slice example reconfiguration failure response or do not receive network slice in preset duration in fact Example reconfigures success response, then into N number of quasi- target BS except the quasi- target for being transmitted across network slice example reconfiguration request In quasi- target BS except base station:The highest quasi- target BS of similarity sends network and is sliced example reconfiguration request, i.e., to Quasi- target BS 2 sends network and is sliced example reconfiguration request, if quasi- target BS 2 reconfigures success, by quasi- target base It stands and 2 is determined as target BS.If the also reconfiguration failure of quasi- target BS 2, continue to send network slice to quasi- target BS 3 Quasi- target BS 3 is determined as target BS by example reconfiguration request if quasi- target BS 3 reconfigures success.If accurate The also reconfiguration failure of target BS 3, it is determined that do not go out target BS, terminate flow.

Further, if reconfiguring successful probability to improve, and the reliability of terminal switching, Ke Yijin are improved According to the corresponding similarity of each quasi- target BS, terminal optionally is determined from N number of quasi- target BS for the multiple preparation of row The target BS that need to switch, including:Into N number of quasi- target BS:The sequence sequence of similarity from high to low is at preceding P of P The quasi- target BS of each of quasi- target BS sends network and is sliced example reconfiguration request;Wherein, network slice example re-matches Set the information that request includes the corresponding network slice example of terminal;P is the positive integer no more than N;Network is sliced example and re-matches It is real for making the network that the quasi- target BS for receiving network slice example reconfiguration request includes to itself be sliced to set request Example carries out reconfiguration operation, so that the information of the corresponding network slice example of network slice example compatible terminal after reconfiguring; If receiving at least one network slice example that P quasi- target BS return reconfigures success response, from least one net Network slice example, which reconfigures in the corresponding quasi- target BS of success response, determines target BS.

In order to ensure that time delay is most short, another optionally scheme is, if receiving a base station in P quasi- target BS The network slice example of return reconfigures success response, then the network received earliest slice example is reconfigured success response Corresponding quasi- target BS is determined as target BS, and remaining P-1 quasi- target BS send weight into P quasi- target BS Configure mandatum cassatorium;Wherein, it reconfigures mandatum cassatorium and example is sliced to network for making remaining P-1 quasi- target BS cancel Reconfiguration operation.Specifically, source base station sends network to multiple quasi- target BS and is sliced example reconfiguration request, once it connects It receives network slice example and reconfigures success response, i.e., it is the received that network slice example, which reconfigures success response, One network slice example reconfigures success response, illustrates that network slice example reconfigures the corresponding quasi- target base of success response The time delay stood is shorter, then network slice example is reconfigured the corresponding quasi- target BS of success response is determined as target BS. In this way, can be reconfigured to avoid remaining P-1 quasi- target BS, network resource consumption is saved.

In a kind of possible realization method, it includes reconfiguring rear network to be sliced that network slice example, which reconfigures success response, The information of example;Wherein, the network slice example compatible terminal reconfigured indicated by the information of rear network slice example is corresponding The business that network slice example indicated by the information of network slice example is carried;Network slice example reconfigures success response It is to be obtained after target BS reconfigures the existing network in base station slice example.Optionally, in the embodiment of the present application After network that quasi- target BS includes to itself slice example reconfigures, the network slice example after reconfiguring is not only also The business run before network slice example reconfigures can be run, the corresponding network of also compatible terminal is sliced the letter of example Breath, you can the business that the corresponding network slice example of operation terminal is supported.Optionally, the net after being reconfigured on quasi- target BS The mark of network slice example can change, for example to be changed to corresponding with the terminal network slice mark of example identical, can also It does not change.

If there are N number of quasi- target BS in M adjacent base station;The quasi- target BS of each of N number of quasi- target BS meets item Part:It is more excellent than the service performance that access Current Serving BTS obtains that terminal accesses quasi- target BS;N is the positive integer no more than M; Source base station is sliced the information and the corresponding net of terminal of example according to the signal quality of M adjacent base station, the network of M adjacent base station Network is sliced the information of example, and the target BS that terminal need to switch is determined from M adjacent base station, including:If being cut in the presence of by network K quasi- target BS of the information matches of the information of piece example network slice example corresponding with terminal, then:Network is sliced real K quasi- target BS of the information matches of the information network slice example corresponding with terminal of example are determined as target BS;Wherein, K is the positive integer no more than N.

After determining target BS that terminal need to switch in M adjacent base station, source base station can also be sent out to target BS Send switching request;Wherein, switching request includes the information of the corresponding network slice example of terminal;Source base station receives target BS The handoff response of return;Wherein, handoff response includes the information of the network slice example to be accessed of terminal;Wherein, waiting Network slice example indicated by the information of the network slice example entered:The information institute of the corresponding network slice example of compatible terminal The business that the network slice example of instruction is carried.The process of target BS is switched to realize terminal, and terminal is made to connect In the network slice example for entering to be capable of in target BS the information of the corresponding network slice example of compatible terminal, ensure terminal traffic Do not interrupt.
