Description

Method, Apparatus and system are determined in a kind of WLAN load

Technical field

The present invention relates to the communication technology, relate in particular to a kind of WLAN load Fang of determining method, Zhuan Ge and system.

Background technology

Along with the appearance of new wireless access technology, the development trend of future network is a heterogeneous network that merges multiple wireless access technology.Current typical access technology has 3GPP(3rd Generation Partnership Project, third generation partner program) definition UMTS(Universal Mobile Telecommunications System, Universal Mobile Telecommunications System), LTE(Long Term Evolution, Long Term Evolution), LTE-A(Long Term Evolution-Advanced, Long Term Evolution strengthens) and non-3GPP definition typically such as WIFI(Wireless Fidelity, Wireless Fidelity) etc. technology.

In following typical networking LTE will with WLAN(Wireless Local Area Network WLAN (wireless local area network)) merge, as shown in Figure 1.LTE wide coverage, covers usually used as wide area, can provide good mobility support for user.And WLAN coverage is little, cover as focus, can better solve in a large amount of concentrated business demands of some hot zones.LTE and wlan network have good complementarity, and the effective combination of the two can effectively improve the service bearer ability of network.For the user in overlapping covered, how for user selects a suitable network, and in the time that LTE or WLAN occur that load is excessive, how to carry out load balancing be vital problem.

In the interoperability specification of existing LTE and WLAN, UE(User Equipment, subscriber equipment) selection to network and load balancing adopt is a kind of based on ANDSF(Access Network Discovery and Selection Function, access network discovery and selection function) scheme.ANDSF strategy is the relevant network selection of a series of operators definition and criterion and the hobby of route, and this criterion has had influence on mobility between the system of UE and determined.Particularly, as shown in Figure 2, wherein UE and ANDSF be by S14 interactive interfacing for the framework of communicating by letter between ANDSF and UE, this interface be one based on IP(Internet Protocol, Internet Protocol) interface.The Pull(that communicated by letter between UE and ANDSF draws) and Push(push away) two kinds of patterns, the former is that UE initiatively sends request to ANDSF, the latter is ANDSF active push information.ANDSF strategy is more static.

ANDSF provides Network finding and selects relevant information to terminal based on carrier policy, comprise following three classes: ISMP(Inter-system mobility policy, the mobility strategy of cross-system), ANDI(Access Network Discovery Information, access network discovery information) and ISRP(Inter-System Routing Policy, cross-system routing policy).

Wherein, ISMP is rule and the preference information of a series of operators definition, this policy definition whether allow that cross-system moves, the most applicable access EPC(Evolved packet core, the block core of evolution) the information such as access technology type, the different priorities of different access technologies.ISMP can be prewired in terminal, also can in the time of terminal request, send, or under certain triggers, be pushed to terminal by ANDSF.For example, ANDSF can issue the priority of WLAN higher than the strategy of LTE, like this, when terminal covers lower time at the two, can preferential choose WLAN system access.

ANDSF can for terminal provide in its vicinity can with, the access network list and the relevant parameter that meet asked access style, if access technology is (as WLAN, WiMAX(Worldwide Interoperability for Microwave Access, worldwide interoperability for microwave access) etc.), Radio Access Network mark, carrier frequency etc.

ISRP comprises the required information of some cross-system routes; for the terminal with many radio access interfaces; as support IFOM(IP Flow Mobility; IP flows mobility) or MAPCON(Multi Access PDN Connectivity; multiple access PDN connect) terminal; these information can for determine: a) in the time meeting specific route conditions, with which kind of can with access network send data; B) for specific IP traffic and/or specific APN(Access Point Name, APN), when disabled certain access network is.

Existing protocol regulation, ANDSF selects to offer ISMP, ANDI and the ISRP of terminal according to Carrier Requirements and roaming agreement, and ANDSF can provide above-mentioned three kinds of strategies simultaneously, and partial strategy wherein also can be only provided.ANDSF can with carrier network in some databases mutual, as HSS(Home Subscriber Server, home subscriber server), to obtain required information.

On the whole, ANDSF is mainly carrier policy and user signing contract information, follows current network load condition without any relation.And UE is getting after ANDSF strategy, directly carry out the process that subsequent network is selected and data flow is switched, this process lacks traditional network controls.The problem that the method exists is, because Access Network (RAN) side (comprising the Access Network side of 3GPP and non-3GPP) is not controlled this process, may cause quality of service in this handoff procedure to be guaranteed.For example, if user is switched to WLAN networking according to ANDSF strategy, and wlan network now transships, and cannot meet user's basic service demand, now will user be experienced and be affected greatly.

Lower mask body is introduced existing measurement mechanism in LTE system:

In LTE system, base station sends to UE the Pei Ge information of measuring by dedicated signaling mode, and UE measures according to the content of measuring Pei Ge information, then measurement result is reported to network.LTE has defined several measurements as Types Below at present: the isosystem measurement of the isosystem measurement of common frequency measurement, different-frequency measure, UTRA frequency, the isosystem measurement of GERAN frequency, CDMA frequency.

What network was measured Pei Ge use is that RRC connects reprovision process, as shown in Figure 3.

The institutional framework of measuring Pei Ge information is as follows:

Measuring object (measurement object): for frequently same and different-frequency measure, measurement unit is frequency; For the isosystem measurement of UTRA frequency, measuring object is a series of communities on certain UTEA carrier frequency; For the isosystem measurement of GERAN frequency, measuring object is a series of GERAN carrier frequency; And for the isosystem measurement of CDMA frequency, measuring object is a series of communities on certain carrier frequency;

Report Pei Ge (report configuration): according to trigger type be divided into Event triggered report with the cycle trigger report, the each Pei of reporting Ge has independent ID.The threshold value and the duration (Time to Trigger) that meets trigger condition that report the some events of Pei Ge meeting dispensing of Event triggered type, the object (for example, reporting CGI) that reports Pei Ge meeting dispensing periodic triggers of periodic triggers type.Also comprise in addition triggering measuring amount, reporting measurement amount, reports the information such as interval, number of times.

LTE is intrasystem at present comprises with frequency/different-frequency measure event:

Event A1 (Serving becomes better than threshold, Serving cell channel quality is greater than thresholding), Event A2 (Serving becomes worse than threshold, Serving cell channel quality is less than thresholding), Event A3 (Neighbour becomes offset better than serving, adjacent cell channel quality is better than Serving cell channel quality), Event A4 (Neighbour becomes better than threshold, adjacent cell channel quality is greater than thresholding), Event A5 (Serving becomes worse than threshold1 and neighbour becomes better than threshold2, Serving cell channel quality is less than thresholding 1, adjacent cell channel quality is greater than thresholding 2 simultaneously), Event B1 (Inter RAT neighbour becomes better than threshold, different system signal quality is better than certain thresholding), (Serving becomes worse than threshold1and inter RAT neighbour becomes better than threshold2 Serving cell channel quality is less than thresholding 1 to Event B2, different system adjacent cell channel quality is greater than thresholding 2 simultaneously)

Wherein, the parameter relating to when measurement comprises:

Measure mark (measurement ID): independent ID, can connect a measuring object simultaneously and report Pei Ge.Open if reached the thresholding of measuring, UE can judge whether to carry out this kind of measurement according to measuring having or not of mark;

Other parameters: also may comprise that measuring amount joins Ge, measure other parameters such as opening thresholding and speed state parameter.

Fig. 4 for example understands measuring object, reports the relation of joining Ge and measuring mark three.

Measurement has reported three kinds of triggering modes: Event triggered reports, periodic report, Event triggered periodic report.These three kinds of modes are joined the combination of various parameters in Ge and are distinguished according to reporting.For example, be Event triggered when reporting the triggering type in Pei Ge, and dispensing certain event threshold value and meet the relevant parameter such as duration of trigger condition, while not having the Ge of joining measure interval or report the parameters such as number of times, UE will report according to an Event triggered mode.

As shown in Figure 5, measurement result will be by measurement report(measurement report) information reporting.

Measuring reporting message for every only can report to measure the corresponding content of mark, under a frequency, meet the relevant PeiGe community that reports, measuring reporting message content has: measure mark, the each measuring amount in this community (RSRP(Reference Signal Received Power, Reference Signal Received Power) and RSRQ(Reference Signal Received Quality Reference Signal Received Quality)) and the physical-layer cell ID of the adjacent cell that satisfies condition, wherein, whether report each adjacent cell measurement amount and CGI to depend on whether Pei Ge UE reports these information to network, ).

The flow process that measurement reports is as follows:

Measure under mark at each, be divided into measurement assessment and report two processes with tissue:

A) measure assessment: UE by measuring, search out in certain measuring object to meet and report PeiGe community, assess, when community within a certain period of time (TimeToTrigger) all meet entry criteria, will be comprised in report list; Once You Xin community enters report list, will trigger the process that reports.

B) tissue reports: fill in the process of measuring reporting message, need to fill in and measure mark, this cell measurement information, measurement information in neighbor cell.The procurement process of measurement information in neighbor cell is that quality-ordered is carried out according to reporting measurement amount given in Pei Ge in the community comprising in the report list generating during by measurement assessment, inserts measurement reporting message by order from high in the end.

The number of the adjacent cell comprising in report list is by following conditional decision:

A) entry criteria of report list: for example, when the measuring amount of certain community has reached access criterion (, the signal quality of this community is greater than certain threshold value);

B) condition of leaving of report list: leave criterion (for example, the signal quality of this community is less than certain threshold value) when the measuring amount of certain community has reached;

C) community is comprised in the condition of report list: when certain community within a certain period of time (TimeToTrigger) all meet the entry criteria of report list, will be comprised in report list.

D) community deleted condition from report list: when certain community within a certain period of time (TimeToTrigger) all meet the condition of leaving of report list, will be deleted from report list.

In the time that UE reports, all adjacent cells of still staying in report list all can be reported to network, do not consider this community whether before report process in be reported.

But the strategy based on ANDSF is not considered the load information of RAN at present, make user cannot ensure communication quality in the time carrying out network selection and switch, LTE network element can not get load and other information of WLAN.
