Description
Technical field
The present invention relates to the power-saving technology in the communication system, particularly a kind of method of selecting to activate the sub-district.
Background technology
In order to realize energy saving (Energy Saving is called for short ES), can adopt specific mechanism to turn-off the radio frequency of some sub-district (RF), pollute to reduce wireless signal.Such as, on daytime, the personnel in office area increase, and traffic carrying capacity increases, and uptown number reduces; Evening is then opposite.Just can turn-off the RF of a part of uptown sub-district by day, open evening again; And turn-off the RF of the sub-district in a part office area evening, open daytime again.
The ES scene that the application relates to has two kinds, in these two kinds of scenes, provides basic cell covered to be called coverage cell, and the sub-district that is used to the capacity that promotes in the hot spot region is called capacity and promotes the sub-district.Concrete, Inter-RAT ES scene is as shown in Figure 1.The network that the sub-district A of 2G, 3G and B form seamless covering, hot spot region therein arrange that E-UTRAN sub-district C, D, E, F, G are to increase power system capacity and specific LTE service is provided.Wherein, A and B are coverage cell, and C, D, E, F, G are that capacity promotes the sub-district.
Inter-eNB ES scene is as shown in Figure 2, and coverage cell and capacity promote the sub-district and be the E-UTRAN sub-district, and sub-district A and B provide basic covering, and sub-district C, D, E, F, G are arranged in hot zones and are used for the lifting capacity.
In present ES technology, have only capacity to promote the sub-district and can be turned off/activate.The ES mechanism of having adopted at present based on signaling is: the shutoff that capacity promotes the sub-district promotes sub-district self based on the load judgement by capacity; User with this sub-district after satisfying condition switches to coverage cell; Send configuration update message to adjacent base station, get into resting state; Capacity activates the activation of sub-district to be judged based on load by coverage cell, and the request of activation is sent to capacity lifting sub-district in the back that satisfies condition, and capacity promotes the sub-district answer and activates response, and notifies other adjacent base station with configuration update message.
In addition, shutoff/activation also can be controlled by OM.
Fig. 3 is the user distribution sketch map of a kind of supposition in the ES technology.Wherein, sub-district 1 is a coverage cell, and sub-district 2 is that capacity promotes the sub-district with sub-district 3.In scene shown in Figure 3, suppose sub-district 2 and sub-district 3 all in resting state, sub-district 1 finds that the duty ratio of this sub-district is higher, needs to activate other sub-districts.If do not activate the selection of sub-district, then sub-district 1 can be activated sub-district 2 and sub-district 3 simultaneously, and the 1 switching user in the past from the sub-district can be admitted with sub-district 3 in sub-district 2 afterwards.But in fact, possibly only activate wherein some sub-districts and just can share the load of sub-district 1 effectively according to user's distribution situation.For example in Fig. 3, sub-district 2 can be shared the load of sub-district 1 effectively, need not activate sub-district 3.
There are two kinds of possible results the activation sub-district of not doing selection:
1. sub-district 3 has small number of users, but is not enough to reach the condition that it gets into resting state.Though the traffic carrying capacity of sub-district 3 is little, its downlink power amplifier function is still to be opened, and also is equivalent to free-runing operation in fact, has consumed a large amount of power equally.Therefore energy-saving efficiency is lower.
2. another kind of situation is that sub-district 3 numbers of users seldom reach condition thereby deexcitation that it gets into resting state after operation a period of time.But before deexcitation, can its user be switched go back to sub-district 1, can cause table tennis to switch like this, bring harmful effect to user experience.
Several kinds of methods of selecting to activate the sub-district that propose now are:
Method A: use predefined strategy
When coverage cell detects high load capacity, use the strategy define in advance, strategy comprises that each capacity promotes " the underload period " of sub-district, for example turn-offs the sub-district at 12 in evening, 7 of mornings activates the sub-district.This information can obtain from OM.
Method B: measure based on the end lifting amount (IoT) of making an uproar
When coverage cell detected high load capacity, request was in the capacity lifting sub-district of resting state and opens monitor function, and report IoT measures.
Method C: measure based on UE
When coverage cell detected high load capacity, the capacity that request is in resting state promoted sub-district entering " acquisition mode ", transmits control signal, and continued a period of time (be called and survey the period).Resting state can be got back in these sub-districts after surveying past period.UE in the coverage cell can promote the sub-district to capacity and carry out the reference signal measurement, and the feedback measurement result.Can determine to activate which capacity based on the measurement result coverage cell and promote the sub-district.
Method D: locating information
When coverage cell detects high load capacity, utilize the position of UE and position, radius, the transmitting power of capacity lifting sub-district to decide which capacity of activation to promote the sub-district.
All there is certain shortcoming in the above-mentioned several kinds of methods that activate cell selecting.Method A need artificially collect data, and to be used for information judged be the statistics of storing in advance, can not dynamically adjust according to real time information, so accuracy is not high, may influence user's QoS; Method B need be in the sub-district of resting state and open monitor function, and is influential to energy-saving effect; Method C need increase new X2 signaling and be used for request capacity lifting sub-district entering acquisition mode; Method D has requirement to the UE ability, and complexity is higher.
