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) the UMTS(Universal Mobile Telecommunications System of definition, 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, as focus, cover, 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 when LTE or WLAN occur that load is excessive, how to carry out load balancing be vital problem.
In the interoperability standard of existing LTE and WLAN, UE(User Equipment, what subscriber equipment) selection of network and load balancing are adopted 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.UE draws with the Pull(that communicated by letter between ANDSF) 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) access technology type, the information such as different priorities of different access technologies.ISMP can be prewired in terminal, also can when 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 provide access network list and relevant parameter available, that meet asked access style in its vicinity for terminal, if access technology is (as WLAN, WiMAX(Worldwide Interoperability for Microwave Access, worldwide interoperability for microwave access) etc.), Radio Access Network sign, 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 connection) terminal; these information can be for determining: a) when 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, also can only provide partial strategy wherein.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 after getting 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 (the Access Network side that comprises 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 triggering type, be divided into Event triggered and report with the cycle and trigger and report, each reports Pei Ge to have 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 threshold1and 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 during measurement comprises:
Measure sign (measurement ID): independent ID, can connect a measuring object simultaneously and report Pei Ge.If reached, open the thresholding of measuring, UE can judge whether to carry out this kind of measurement according to measuring having or not of sign;
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 sign 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, triggering type in reporting Pei Ge is Event triggered, and dispensing certain event threshold value and meet the relevant parameters 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 sign, under a frequency, meet the relevant PeiGe community that reports, measuring reporting message content has: measure sign, each measuring amount of 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:
At each, measure under sign, be divided into measurement assessment and report two processes with tissue:
A) measure assessment: UE by measuring, search out in certain measuring object and 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 sign, 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, by order from high in the end, inserts measurement reporting message.
The number of the adjacent cell comprising in report list is by following conditional decision:
A) entry criteria of report list: the measuring amount when certain community has reached access criterion (for example, 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.
When 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, LTE network element cannot get the loading condition of WLAN.
