Accordingly, the present invention also provides the waken system of a kind of RN, and described system comprises: network side and RN, and wherein, network side is used for judging when waking described RN up according to the strategy that wakes up that sets in advance, and sends to described RN and wakes indication up; RN, be used for according to set in advance wake up strategy judge when waking self up or receive that described network side sends wake indication up the time, carry out wake operation.
Wherein, described RN is one or more, the described network side of access and is in the RN of park mode.
Wherein, described RN also is used for entering mode of operation from park mode, opens the service of RN residential quarter; Perhaps, again access the DeNB residential quarter with the RN identity, open the service of RN residential quarter.
Wherein, described RN, can also judge need to wake self up and carry out mode of operation after, by high-level signaling or/X2 interface notifies described network side self to enter mode of operation.
Wherein, described RN can also be after receiving described network side sends wake indication up and carry out the wake operation of self, returns to described network side and wake success message up or wake failed message up.
For example, at network side, such as OAM or DeNB, pre-set following RN and wake strategy up: RN at the appointed time in the section or RN when being positioned at the appointed area, wakes RN up and enters mode of operation from park mode.Particularly, at the appointed time in the section or RN when being positioned at the appointed area, network side sends to described RN and wakes indication up, and perhaps described RN wakes self up, so that described RN is from park mode cut-in operation pattern.Here, described network side can the described RN of Real-time Obtaining present position information or current time information, judge that described RN is whether in the appointed area or judge that whether at the appointed time the current time in the section, if, then send to described RN and wake indication up, wake described RN up, otherwise, do not send described waking up and indicate to described RN.Described RN also can measure information or the Real-time Obtaining current time information of self present position in real time, judges self-position whether in the appointed area or judge that whether at the appointed time the current time in the section, if so, then wake self up, otherwise, do not wake self up.
Again for example, described network side or RN can according to wireless channel environment, judge whether to wake RN up.Particularly, the channel situation of described network side and/or RN monitoring Direct Link and/or Access Link, the channel disturbance degree of concrete monitoring Direct Link and/or Access Link, signal to noise ratio, letter interference ratio etc., according to the thresholding that wakes up of that pre-set, corresponding described channel situation, judge and wake described RN up.So, when wireless channel environment in the network changes, can make RN enter mode of operation from park mode by waking RN up, open the service of RN residential quarter, reach the lifting network performance, meet consumers' demand, improve the effects such as the network coverage.Here, the channel disturbance degree of described Direct Link and/or Access Link, signal to noise ratio, letter interference ratio etc. can be measured respectively acquisition or be obtained and report described network side by the RN measurement by network side and RN.
Again for example, for the mobile RN that is carried on car and boat, can judge waking up of RN according to the movement velocity of RN place car and boat.Wherein, the movement velocity of RN place car and boat can be measured by network side and obtain, or measures acquisition by RN, or measures and report network side by RN.For the RN in the movement, described network side can be preset a speed threshold, and described speed threshold can be a certain concrete velocity amplitude, and such as 5km/h, when the movement velocity of described RN place car and boat was higher or lower than described speed threshold, the network side indication woke RN up; Perhaps, can also be by network side with speed threshold configuration indication to RN, the movement velocity of RN monitoring self place car and boat, when the movement velocity of self place car and boat was higher or lower than described speed threshold, RN woke self up.In addition, can also wake velocity interval up by default one, i.e. speed interval, such as 5-10km/h, when waking up in the velocity interval, RN wakes self up or the indication of described network side wakes described RN up described for the movement velocity of RN place car and boat.
Again for example, for the mobile RN that is carried on car and boat, the distance between RN and the DeNB changes along with the motion of car and boat, and the distance between concrete RN and the DeNB can be measured by network side and obtain, or measures acquisition by RN, or is measured and the report network side by RN.Network side can arrange distance threshold, and described distance threshold can be a concrete distance value, and such as 5km, when the distance between RN and DeNB was higher or lower than described distance threshold, the network side indication woke RN up; Perhaps by network side described distance threshold configuration is indicated to RN, the distance between RN monitoring self and the DeNB, when the distance between RN and DeNB was higher or lower than described distance threshold, RN woke self up.In addition, can also wake distance range up by default one, namely between distance regions, such as 5-10km, described when waking up in the distance range, RN wakes self up or the indication of described network side wakes described RN up in the distance between RN and the DeNB.
Again for example, the user UE quantity in the RN coverage and/or when being in UE quantity that RRC connects (RRC Connected) state and satisfying default UE quantity thresholding is waken described RN up.So, network side can be according to the variation of offered load, and indication wakes RN up, makes RN enter mode of operation from park mode, opens the service of RN residential quarter, the purpose that reach and share offered load, improves network performance.Here, offered load refers to number of users in the network, user data demand etc., comprises UE quantity in the RN coverage and/or is in the UE quantity of RRC Connected state.
Again for example, can and be in the RN quantity of service state according to the current access of the DeNB of RN, judge whether to wake described RN up.When the RN quantity of the current access of the DeNB of RN was lower than default RN quantity thresholding, network side indication woke the one or more RN among the current a plurality of RN that are in park mode up, makes it enter mode of operation from park mode, opens the service of corresponding RN residential quarter.During practical application, when the RN quantity of home base station (DeNB) access was lower than default RN quantity thresholding, home base station (DeNB) is judged need to wake one or more RN of current access self up, and woke indication up to described one or more RN transmissions; Described one or more RN enters mode of operation from park mode.
