Detailed description of the invention
The embodiment of the present application is intended to protective seletion method and terminal, can be applicable to LTE system or the scene of various communication technology/network/system competitive coexistence。
In the application, noun " network " and " system " are often used alternatingly, but it will be appreciated by those skilled in the art that its implication。
Above-mentioned LTE system can include base station and terminal。
In R13, introducing LAA (Licensed-AssistedAccess authorizes auxiliary to access) technology, base station can utilize mandate frequency spectrum to provide communication service for terminal together with unlicensed spectrum simultaneously。That is, LTE system is except authorizing frequency spectrum, it is also with unlicensed spectrum and carries out data transmission。Simultaneously it is also possible to there is other network/system to use unlicensed spectrum, for instance wlan network。For ease of address, mandate frequency spectrum is called f1 by the present invention, and unlicensed spectrum is called f2。
In unlicensed spectrum, each communication system/network accesses based on the mode of competition, and therefore, the communication quality in unlicensed spectrum and experience might not be protected。Additionally, wlan network is usually monthly payment service, it is not limiting as flow；And LTE wireless network generally according to flow charging (being likely to by flow charging) in unlicensed spectrum。When having multiple network in unlicensed spectrum, user may want to the network that priority access rate are relatively low。
To sum up, for user, there is the demand choosing whether to use wireless network (or being called LTE network) at unlicensed spectrum transmitting data。
But, referring to Fig. 1, existing LTE terminal, for wireless network (in Fig. 1 the switch of " data cube computation " corresponding wireless network), only opens and closes two kinds of selections。That is, existing LTE terminal does not provide a user with the options for unlicensed spectrum transmitting data。
Further, in LTE system, terminal is that the scheduling according to base station receives or sends data, if uses wireless network to be determined by base station at unlicensed spectrum transmitting data, but not is determined by terminal。Therefore existing LTE terminal, it is impossible to whether using wireless network to be controlled at unlicensed spectrum transmitting data。
For this, the embodiment of the present application provides the method (abbreviation system of selection) that terminal selects unlicensed spectrum and the terminal performing the method。
The basis of said method is base station and terminal all supports LAA。Terminal, when meeting unlicensed spectrum and closing condition, performs unlicensed spectrum shutdown strategy, thus realizing controlling whether to use wireless network at unlicensed spectrum transmitting data。
More specifically, for different scenes, above-mentioned unlicensed spectrum closes the content difference that condition comprises, and accordingly, the content of unlicensed spectrum shutdown strategy is also not quite similar。
Below above-mentioned system of selection is described in detail by branch scape。
Scene one, terminal does not access wlan network, and, terminal is connected with base station。
Two kinds of situations are once comprised in scene:
Situation one, terminal is only set up with base station on f1 and is connected；
Situation two, terminal is all set up with base station on f1 and f2 and is connected。
In situation one (terminal is only set up with base station on f1 and is connected), the interactive flow process of terminal and base station can referring to Fig. 2 a, and it can comprise the steps:
200 parts: support that the base station of LAA issues the inquiry message whether supporting LAA；
When only base station and terminal all support LAA, just can perform the system of selection that the embodiment of the present invention provides。Therefore, base station needs to know whether terminal supports LAA。
201 parts: in response to above-mentioned inquiry message, terminal returns response message, carries and characterize the information supporting LAA in this response message。
In one example, the response message in existing standard agreement can be adopted to carry and to characterize the information supporting LAA。In another example, it is possible to adopt newly-increased message to carry above-mentioned information。
Certainly, when terminal does not support LAA, terminal also can return to response message, and simply this response message carries and characterizes the information not supporting LAA。
More specifically, can adopt numerical value 0,1 characterizes whether support LAA。
202 parts: when terminal is not set up with base station in unlicensed spectrum and is connected, terminal searches for cell information in unlicensed spectrum。
More specifically, terminal can indicate search cell information according to the configuration of base station。
In existing LTE system, terminal to authorize access LTE network on frequency spectrum, must through cell searching, the acquisition process such as cell system information, Stochastic accessing。Wherein, the main purpose of cell searching includes: obtain frequency and sign synchronization with community；Obtain system-frame timing, the i.e. original position of downlink frame；Determine the PCI (Physical-layerCellIdentity) of community。
In one example, terminal to access LTE network in unlicensed spectrum, it is possible to authorizing, by base station, the required information that unlicensed spectrum accesses that issues on frequency spectrum, terminal only need to measure the signal intensity in unlicensed spectrum。
203 parts: under the control switch of terminal is closed, regardless of whether search cell information, terminal to report search failure information。
Select for ease of user, terminal can provide f2 to control switch (referring to Fig. 3 a) on interface, or f2 controls option (referring to Fig. 3 b), when control switch is in opening, characterize and allow to use LTE network at unlicensed spectrum transmitting data, when control switch is closed, characterizes and do not allow to use LTE network at unlicensed spectrum transmitting data。Whether such user can decide in its sole discretion and use wireless network at f2 transmitting data。Owing to terminal type has multiple, interface setting also can have multiple, and the present invention does not specifically limit。
In the present embodiment, unlicensed spectrum is closed condition and is included controlling switch and be closed (can by control switch be closed being called first condition)。
Above-mentioned search failure information is searched for less than cell information for being characterized in unlicensed spectrum。
It should be noted that be closed owing to controlling switch, therefore no matter whether terminal searches cell information, all can report search failure information。So that base station performs follow-up 204 parts。
That is, in the present embodiment, unlicensed spectrum shutdown strategy includes " reporting search failure information to described base station "。
Also do not set up with base station on f2 due to terminal and be connected, therefore can report search failure information by f1。
In one example, terminal can pass through existing RRC (RadioResourceControl) information reporting search failure information。In another example, it is possible to adopt newly-increased message to carry above-mentioned information。
204 parts: base station is according to the search failure information received, and decision-making is not set up with terminal in unlicensed spectrum and is connected。
In the present embodiment, user can pass through to control switch, chooses whether to use wireless network at unlicensed spectrum transmitting data。If controlling switch to be set to off, no matter whether terminal searches cell information in unlicensed spectrum, after search failure information, base station all can be reported to receive search failure information, decision-making can not use unlicensed spectrum。And if control switch be set to open, then terminal can carry on an agreement regulation operation。
The selection mode that the present embodiment provides, both have followed the mechanism determined by base station, can realize again using based on the selection of user or forbid that wireless network is at unlicensed spectrum transmitting data simultaneously。
In situation two (terminal has been set up with base station on f2 and has been connected), the interactive flow process of terminal and base station can referring to Fig. 2 b, and it can comprise the steps:
205 parts: measuring task that terminal issues according to base station, for unlicensed spectrum measures, and obtains actual measured results。
More specifically, terminal can issue according to base station, for the measuring task of unlicensed spectrum, measures whether the signal quality in unlicensed spectrum reaches the requirement of transmission data。
Above-mentioned measuring task can include measuring parameter and measuring item。
Wherein, measure parameter and can include measurement time, bandwidth etc.。For limiting time, the bandwidth that terminal is measured；Measure item and can include at least one in Reference Signal Received Power, Reference Signal Received Quality, reference signal strength and SINR；The measurement result that measurement result is then corresponding for measuring item。
Above-mentioned measuring task can be issued by f1, it is possible to is issued by f2。
It should be noted that in the present embodiment, terminal has been set up with base station on f2 and has been connected, then the inevitable already known terminal in base station supports LAA, then need not perform above-mentioned 200 and 201 parts again。
206 parts: under control switch is closed, terminal abandons actual measured results, and reports the measurement result lower than threshold value to base station。
In the present embodiment, unlicensed spectrum close condition include control switch be closed (first condition)。
For the measuring task that base station issues, terminal can trigger report measurement results according to feedback cycle, or triggers report measurement results according to event。
In the present embodiment, terminal feedback periodic report or the measurement result reported according to event triggering are not actual measured results, and are less than the measurement result of threshold value。This threshold value is the threshold value of regulation in agreement。When measurement result is lower than threshold value, base station will be considered that f2 does not possess the condition of transmission data。
That is, in the present embodiment, unlicensed spectrum shutdown strategy includes " abandon actual measured results, and report the measurement result lower than threshold value to base station "。
It should be noted that the time of base station sending measuring task, can occur before user setup control switch is closed, it is possible to occur after user setup control switch is closed。
207 parts: base station is according to the measurement result lower than threshold value, and decision-making does not use wireless network at unlicensed spectrum transmitting data。
In the present embodiment, user can pass through to control switch, chooses whether to use wireless network at unlicensed spectrum transmitting data。If controlling switch to be set to off, then terminal to report is lower than the measurement result of threshold value, after base station receives above-mentioned measurement result, decision-making can not use unlicensed spectrum。This kind of processing mode, both have followed the mechanism determined by base station, can realize again using based on the selection of user or forbid that wireless network is at unlicensed spectrum transmitting data simultaneously。
Scene two, terminal is connected with base station, and terminal accesses WLAN。
Two kinds of situations are comprised for two times equally in scene:
Situation one, terminal is only set up with base station on f1 and is connected；Situation two, terminal is all set up with base station on f1 and f2 and is connected。
Wlan network is usually monthly payment service, is not limiting as flow, so user can arrange wlan network priority higher than wireless network。Or, terminal just arranges the priority of wlan network higher than wireless network when dispatching from the factory。
Existing terminal has been provided for select function for the switch of WLAN (wifi)。After user selects unlatching WLAN, wifi signal can be scanned for by terminal, then allows user select in the form of a list。Or, the wifi network that terminal once can access before being directly accessed。
If terminal access wlan system, and can proper communication, can design be automatically switched off wireless network in unlicensed spectrum data transmission。
For situation one, can referring to Fig. 4 a in the interactive flow process realizing being automatically switched off wireless network data transmission in unlicensed spectrum, terminal and base station, it can comprise the steps:
400-402 part is identical with aforesaid 200-202 part, and therefore not to repeat here。
