Embodiment
Basic ideas of the present invention are, in base station and relay station, obtain signal parameter that the user terminal statistics obtains and with corresponding business channel switching threshold relatively, as satisfy switching condition, then the base station indicates this user terminal to carry out Traffic Channel to switch.
Describe the present invention below in conjunction with drawings and Examples.
Fig. 2 is the Traffic Channel changing method flow chart of embodiment of the invention junction network, and as shown in Figure 2, this method comprises following steps:
101: base station, relay station and user terminal are each class business setting service priority;
Service priority is that business is divided into different grades according to demand, with the grade of service quality (Quality ofService, be called for short QoS) be corresponding.For each class business, base station, relay station and user terminal are provided with identical service priority for it.
102: the selected signal parameter that is used for the Traffic Channel switching judging of base station, relay station and user terminal, the base station is provided with corresponding switching threshold, keeps threshold value and switching condition in conjunction with service priority and traffic channel types;
Above-mentioned signal parameter be for can reflecting the parameter of the Traffic Channel quality between terminal to base station or relay station in real time, and (Timing Advance TA) waits or is the combination of above parameter as signal strength signal intensity, signal quality, Timing Advance.
The Traffic Channel switching threshold is a threshold value that is used to judge whether to switch to from other Traffic Channel this Traffic Channel.Except with selected signal parameter and service priority mutually outside the Pass, switching threshold can also be relevant with traffic channel types.Traffic channel types comprises two kinds of BTS service channeling and trunking station Traffic Channels.To each signal parameter, the size of its corresponding switching threshold is by service priority and traffic channel types decision.Present embodiment also is provided with one at each signal parameter and keeps threshold value except that switching threshold.This keeps threshold value also can be relevant with service priority and traffic channel types, is a threshold value that is used to judge whether to switch to from this Traffic Channel other Traffic Channel.For same parameter and traffic channel types, keep threshold value and be not equal to switching threshold usually, to avoid frequent switching.Certainly, both can equate that also keep threshold value and be switching threshold this moment.
And switching condition stipulated to satisfy between signal parameter value and corresponding switching threshold which kind of relation (as greater than, more than or equal to, less than, smaller or equal to or other logical relation) time can trigger Traffic Channel and switch, can adopt single parameter to judge, also can a plurality of parameter combinations get up to judge.
Have only and satisfy this two sub-conditions simultaneously, just satisfied switching condition at last.
103: user terminal access base station and/or relay station in base station and relay station signal cover, set up control channel and Traffic Channel and initiate professional;
Control channel and Traffic Channel that user terminal is set up comprise following several situation: A, and control channel and Traffic Channel are the channel between terminal and the base station; B, control channel and Traffic Channel are the channel between terminal and the relay station; C, control channel are the channel between terminal and the base station, and Traffic Channel is the channel between terminal and the relay station; D, control channel are the channel between terminal and the relay station, and Traffic Channel is the channel between terminal and the base station.
The Traffic Channel of in the literary composition the current selection of user terminal being used that is provided by institute's access base station or relay station is called resident Traffic Channel.Will be except that resident Traffic Channel, this user terminal can select to set up but still unfounded other Traffic Channel is called non-resident Traffic Channel.
With the user terminal among Fig. 11 is example, when inserting as this user terminal 1, select to have set up and the base station between Traffic Channel, the Traffic Channel between itself and the base station is called resident Traffic Channel; As this user terminal 1 can also set up and relay station 1 between Traffic Channel, the Traffic Channel between itself and this relay station 1 is called non-resident Traffic Channel.
At resident Traffic Channel and non-resident Traffic Channel, switching condition can be divided into two sub-conditions:
The first sub-condition: be directed to resident Traffic Channel, user terminal needs to switch to from this Traffic Channel the condition of other Traffic Channel, the base station that Traffic Channel is provided that obtains as user terminal statistics or the signal strength signal intensity of relay station or signal quality less than or smaller or equal to the reservation threshold value of this parameter, the lead of user terminal greater than or more than or equal to the reservation threshold value of this parameter;
The second sub-condition: be directed to non-resident Traffic Channel, user terminal can switch to the condition of this Traffic Channel from other resident Traffic Channel, the base station of the provided Traffic Channel that obtains as user terminal statistics or the signal strength signal intensity of relay station or signal quality greater than or more than or equal to the switching threshold of this parameter, Timing Advance less than or smaller or equal to the switching threshold of this parameter.
104: base station recording user terminal is used professional service priority (the following teleservice priority that also abbreviates as);
105: user terminal obtains to be provided Traffic Channel and can provide the base station of Traffic Channel and the signal parameter of relay station, and passes through the information reporting base station or the relay station of control channel;
When the base station provides control channel for user terminal, or base station and relay station be when providing control channel for user terminal simultaneously, and user terminal sends to the base station with signal parameter value; When relay station provided control channel for user terminal, user terminal sent to relay station with signal parameter value.For resident Traffic Channel, also can adopt other parameter, as the direct parameter of reflection Traffic Channel quality such as the signal to noise ratio of descending signal, the error rate, these parameters report after can being detected by terminal.
Above-mentioned signal parameter value can be that user terminal is added up signal parameter, the statistical value of the signal parameter of acquisition.Carry out signal parameter and add up the method that can adopt accumulative total average, that is: divide a plurality of timing statistics sheets, statistics is begun to carry out addition to the signal parameter statistical value of current each the timing statistics sheet that comprises get the corresponding accumulative total of average acquisition mean value.Adopt the average mode of accumulative total to carry out the signal parameter statistics, the dynamic change situation of reflected signal parameter value more accurately, the irregular change of erasure signal parametric statistics value.When adopting the accumulative total averaging method to carry out the signal parameter statistics, corresponding reservation threshold value and switching threshold are the accumulative total average threshold.
In the present embodiment, user terminal periodically reports signal parameter value with Fixed Time Interval to base station or relay station, and user terminal can not preserved the Traffic Channel switching threshold and switch sub-condition in this case.In the mode that Fixed Time Interval reports, user terminal also can be preserved the Traffic Channel switching threshold and switch sub-condition, only need report resident Traffic Channel and non-resident Traffic Channel whether to satisfy the subconditional information of above-mentioned switching last giving the correct time.
Among another embodiment, user terminal also can adopt burst to report mode, is promptly changing because of associated signal parameter when satisfying the sub-condition of switching, reports the signal parameter value of this user terminal to base station or relay station with burst mode.In this case, user terminal also needs to be provided with and to preserve the reservation threshold value and/or the switching threshold of each signal parameter.
Certainly, user terminal also can report above-mentioned signal parameter after the indication that receives base station, relay station.For example, when the Service Source of base station or relay station was nervous, the user terminal in signal cover sent signal parameter after sending and reporting Indication message, user terminal to receive this Indication message.
User terminal can report each signal parameter value by sending the Traffic Channel notification message at control channel.If do not keep the switching threshold of relay station signal parameter in the base station and keep threshold value, can in notification message, comprise above-mentioned two threshold values, so that the implication of the signal parameter value that comprises in this notification message is known in the base station.
For example, when adopting signal strength signal intensity as signal parameter, it keeps threshold value accordingly and switching threshold is remembered work: STs and STc, STs＜STc respectively; When the change in signal strength of user terminal is during less than STs or greater than STc, report this signal strength values (or this signal strength values and respective threshold) of described user terminal with burst mode, perhaps report described user terminal to satisfy Traffic Channel and switch sub-condition with burst mode.Present embodiment does not report during less than STc in signal strength signal intensity, is for fear of in some cases, when signal strength signal intensity fluctuates up and down near STc, causes user terminal frequently to report related news to the base station.
The report mode and the burst of above fixed intervals report mode to adopt simultaneously.
106: the relay station that receives the message that reports is transmitted this message to affiliated base station;
107: the Traffic Channel switch decision is carried out according to the base station in the message of receiving and the signal parameter value of relay station in the base station, as satisfying the Traffic Channel switching condition that is provided with, carries out next step; Otherwise, jump to step 105;
For example, when adopting signal strength signal intensity as signal parameter, it keeps threshold value accordingly and switching threshold is remembered work: STs and STc, STs＜STc respectively; When the signal strength signal intensity of base station that Traffic Channel is provided or relay station during, do not carry out Traffic Channel and switch less than STc and greater than STs.The signal strength signal intensity of having only base station that Traffic Channel can be provided or relay station is more than or equal to corresponding switching threshold, and the signal strength signal intensity that the base station of Traffic Channel or relay station be provided is less than corresponding when keeping threshold value, when promptly satisfying the first sub-condition and the second sub-condition simultaneously, just adjudicate and satisfy the Traffic Channel switching condition.Adopt signal quality similar as the situation of signal parameter.
When adopting Timing Advance as signal parameter, it keeps threshold value accordingly and switching threshold is remembered work: TAs and TAc, TAs respectively〉TAc; When the Timing Advance of the base station that Traffic Channel is provided or relay station notice terminal during, do not carry out Traffic Channel and switch less than TAs and greater than TAc.Have only base station or relay station that Traffic Channel can be provided to notify the Timing Advance of terminal smaller or equal to corresponding switching threshold, and the Timing Advance that the base station of Traffic Channel or relay station notice terminal is provided is greater than corresponding when keeping threshold value, when promptly satisfying the first sub-condition and the second sub-condition simultaneously, just adjudicate and satisfy the Traffic Channel switching condition.
As can be seen, if signal parameter value keeps between threshold value and the switching threshold (can be described as resident interval) corresponding, then do not carry out Traffic Channel and switch.The purpose of doing like this is when the quality of resident Traffic Channel is in the acceptable scope, even non-resident Traffic Channel satisfies the Traffic Channel switching condition, also needn't carries out Traffic Channel and switch, to avoid the frequent switching of Traffic Channel.
108: the base station is switched message by control channel to the user terminal transmitting channel;
Comprise channel switching type field in the above-mentioned channel switching message, this field is 0 o'clock, and indicating user terminal switches to Traffic Channel by the base station and provides; This field is 1 o'clock, and indicating user terminal switches to Traffic Channel by relay station and provides.
If control channel is based upon between base station and the terminal, the base station can directly be switched message by this control channel with channel and be sent to terminal.Be based upon between relay station and the terminal as control channel, the base station can be switched channel message earlier and be sent to the relay station that terminal inserts, and re-sends to terminal by relay station then.
109: user terminal receives above-mentioned channel and switches and set up after the message and the base station of Traffic Channel or the Traffic Channel between relay station can be provided, and the Traffic Channel of use is switched to the Traffic Channel of this foundation from former Traffic Channel, and former Traffic Channel can discharge.
In another embodiment, because user terminal can be learnt the statistical value of needed all parameters, therefore user terminal also can dispose corresponding switching threshold and switching condition, finishes judgement that Traffic Channel switches in this locality and switches to base station requests by same way as.After receive the base station, can switch indication to the user terminal Return Channel, handle getting final product after user terminal is received in a manner described as agreeing to switch.
In the above-described embodiments, realized the switching of Traffic Channel between base station and relay station.In another embodiment, can use above-mentioned Traffic Channel to keep the grand diversity that threshold value realizes Traffic Channel, promptly user terminal uses base station and two Traffic Channels of relay station simultaneously.The grand diversity of realization Traffic Channel need be carried out the variation of the following aspects to the foregoing description:
In the above-mentioned steps 107, if the result of Traffic Channel switch decision is: the non-resident Traffic Channel of this user terminal satisfies the second sub-condition that Traffic Channel is switched, and the first sub-condition or its signal parameter value that resident Traffic Channel satisfies the Traffic Channel switching are in resident interval; Then judge and can carry out grand diversity operation, promptly base station and relay station can provide Traffic Channel for this user terminal simultaneously;
In the above-mentioned steps 108, when carrying out grand diversity operation, the channel switching type field value that signaling channel switches in the message is 2, and indicating user terminal uses base station and relay station that its Traffic Channel that provides is provided simultaneously;
In the above-mentioned steps 109, user terminal carries out corresponding business channel handover operation according to channel switching type field, as be grand diversity operation, then keep former resident Traffic Channel, and former non-resident Traffic Channel switched to resident Traffic Channel, promptly use base station and relay station that its Traffic Channel that provides is provided simultaneously.
It should be noted that user terminal stride the base station switch (being the sub-district gravity treatment) preceding, the base station needs to switch message to this user terminal transmitting channel, can make the channel switching type field in this message this moment is 3, promptly is designated as the switching of striding the base station; After user terminal is received, carry out the switching of control channel and/or Traffic Channel, and only use in base station or the relay station one to provide control channel and Traffic Channel after guarantee switching for it.
