Embodiment
Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the feature in embodiment and embodiment in the application can be mutually combined.
Mentioned in correlation technique, increased LoadInformation message is consumed largely relative to using before NLB functions
Forward direction time interval resource.By analyzing NLB functional characteristics, when the forward direction load between cell is more uneven, calculated by NLB
The gain that method may be obtained is bigger.The scene of larger gain can be obtained in NLB algorithms, some loads are certainly existed relatively heavy
Cell, in order to support NLB functions and broadcasting Neff information in forward control channel obviously can grab natively nervous forward direction
Time interval resource.
In order to solve the above technical problems, the embodiments of the invention provide a kind of sending method of network load information, at it
Manage flow as shown in Fig. 2 including：
Step S202, network side set the information on load of sector；
Step S204, network side choose whether information on load notifying user terminal according to network the present situation.
In embodiments of the present invention, network side sets the information on load of sector, and further, network side is according to the current shape of network
Condition, chooses whether information on load notifying user terminal.That is, when network the present situation meets some conditions, load can be believed
Breath is notified to user terminal, when current network state does not meet some conditions, can not be notified information on load to user terminal,
When the forward direction load between cell is uneven, for the relatively heavy cell of load, network side can select not believe load
Breath is notified to user terminal, so as to avoid limited forward direction time interval resource from largely being seized.
Wherein, when network side notifies information on load to user terminal, it can be incited somebody to action by the dedicated bearer message newly defined
Information on load is notified to user terminal, can also be notified information on load by extending existing system Overhead Message or broadcast message
To user terminal, other means can also be used, information on load can be notified to user terminal.
When network side is by extending existing system Overhead Message or broadcasting the message to user terminal transmission information on load, network
Side needs to set the information unit of bearing load information in existing system Overhead Message, and then network side is by being provided with carrying
Information on load is notified user terminal by the existing system Overhead Message or broadcast message of the information unit of information on load.
It is preferred that, existing system Overhead Message or broadcast message include forward control channel Overhead Message QuickConfig
Message.
During implementation, the present embodiments relate to network load information be probably Neff information, now said as example
Bright, its handling process of the sending method of Neff information is as follows, including：
Step 1: whether judging before contained fan to load more than pre-determined threshold；
Step 2: if so, broadcasting this cell Neff information in forward control channel Overhead Message QuickConfig, in fact
The transmission of existing Neff information.
In embodiments of the present invention, whether judge before contained fan to load more than pre-determined threshold, if so, in forward control channel
This cell Neff information is broadcasted in Overhead Message QuickConfig, the transmission of Neff information is realized.That is, to load before contained fan
Transfer to broadcast current area in another forward control channel Overhead Message QuickConfig during more than pre-determined threshold
Neff, relative to Neff information is sent using LoadInformation message in the prior art, is saved
LoadInformation message improves the forward direction time interval resource utilization rate of user, is conducive to the preceding occupancy to time interval resource
The forward-link capacity of commercial system is lifted, the network value of operator is lifted.
When existing system Overhead Message or broadcast message selection forward control channel Overhead Message QuickConfig message are held
When carrying information on load, whether network side is judged before contained fan to load more than pre-determined threshold；If so, network side is in QuickConfig
Information on load is broadcasted in message, information on load is notified user terminal by selection.
During implementation, information on load is broadcasted in forward control channel Overhead Message QuickConfig (for example, Neff believes
Breath), it is preferred that the FwdLoadInfo fields for the forward direction information on load for representing this cell can be increased in QuickConfig,
Neff information is broadcasted using increased FwdLoadInfo fields.
During implementation, the length of FwdLoadInfo fields can be 1bit, can be 10bit, can also 2bit, 3bit etc.
Deng, it is preferred that its length can be set to 5bit, can be on the premise of enough Neff information be carried, it is to avoid waste
Ample resources.
Consider the compatibility issue of the old and new's terminal, FwdLoadInfo fields can be arranged on QuickConfig end,
Certainly, when implementing, if in the case of the possible compatibility of the old and new's terminal, FwdLoadInfo fields can also be arranged on
QuickConfig other positions, for example, top, centre, etc..
During implementation, whether judge before contained fan to load more than pre-determined threshold, there can also be another result, i.e. contained fan
Forward direction load is not less than pre-determined threshold, and now, the dedicated bearer message LoadInformation for sending bearing load information disappears
Breath, identical with the sending method of the Neff information in correlation technique, certainly, in the specific implementation, the information on load of carrying is not only
Only include Neff information, it is also possible to which, including other information on loads, the species of information on load is depending on concrete condition.For this is sent out
The method that bright embodiment is provided becomes apparent from clearer with illustrating, and forms clear contrast with correlation technique, hereinafter will be with Neff
The flow of the sending method of network load information is described in detail exemplified by information, if being related to other network load informations such as
Cell access data etc., what its respective handling flow was all similar to.
It can be drawn by the above, by taking the transmission of Neff information as an example, the embodiments of the invention provide Neff information
Sending method includes two parts, and Part I is to work as (i.e. before contained fan lighter to load not less than pre-determined threshold to load before contained fan
Cell) when, sending Neff information using LoadInformation message (includes the forward direction of this cell and the adjacent area of this cell
Information on load), Part II is the profit when exceeding pre-determined threshold (to the cell that load is heavier i.e. before contained fan) to load before contained fan
Neff information (only including this cell information) is sent with QuickConfig.
During implementation, pre-determined threshold can be defined to be preceding to load thresholding FwdSectorHighLoadThresh, utilized
Whether FwdSectorHighLoadThresh sends Neff information come the contained fan for controlling load heavy.The parameter designing is GAUP
(Generic Attribute Update Protocol, conventional updating protocol) consults parameter, and the whole network is unified, is synchronized to by AN
The control channel unit of cell.Compare current area Neff and FwdSectorHighLoadThresh, if Neff is more than thresholding
Value, then send in QuickConfig by the Neff of this cell, Neff information do not retransmited.During implementation, pre-determined threshold is access
Session Session between terminal AT and access network AN consults parameter, it is preferred that pre-determined threshold is designed as strengthening forward traffic channel
The negotiation parameter of MAC layer, and if only if consults when parameter LoadInformationSupported is TRUE effectively, wherein
LoadInformationSupported represents whether AT supports Neff information to decode.
In the transmission process of information on load, if pre-determined threshold is not to load maximum before contained fan, and this cell
When forward direction load is more than pre-determined threshold, the transmission of LoadInformation message is closed, LoadInformation has been saved and has disappeared
Breath improves the forward direction time interval resource utilization rate of user to the preceding occupancy to time interval resource, is conducive to before lifting commercial system
To capacity, the network value of operator is lifted；If pre-determined threshold is before contained fan to load maximum, sent in control channel
LoadInformation message.
To load maximum it is 31dB or 15.5dB before contained fan according to existing agreement.
Using the above method provided in an embodiment of the present invention, the respective handling at AT ends is as follows：
If the QuickConfig (FwdLoadInfo=0) that AT is received, it is believed that current area light load, AT need to continue
LoadInfomation Overhead Messages are received to know the Neff of this cell and Neff of this cell adjacent area.
If QuickConfig (the FwdLoadInfo that AT is received>FwdSectorHighLoadThresh), it is believed that current
Cell heavy load, now AN be not sent further on LoadInfomation Overhead Messages, AT obtains other adjacent areas if desired
Neff, need to be locked to the light contained fan of other loads.
After the Neff values for obtaining all contained fans of activation collection, AT sides perform NLB algorithms, selection SINR (Signal to
Interference plus Noise Ratio, signal noise value) and the maximum contained fan of Neff ratios be used as service contained fan.
Especially, if setting FwdSectorHighLoadThresh parameters to be 31 (15.5dB), then it represents that no matter forward direction
How is load, is required to construction LoadInfomation and is sent in control channel.
After being improved by approach described above, forward direction time interval resource situation analysis：
The transmission cycle for considering LoadInfomation is 512slot, and the QuickConfig transmission cycle is 256slot
Situation：Per 512slot, 8+5+5+32 (adjacent area number) * 5 (bit) * 1 (secondary) -5 (bit) * 2 (secondary)=178-10=can be saved
168bit；
The transmission cycle for considering LoadInfomation is 512slot, and the QuickConfig transmission cycle is 512slot
Situation：Per 512slot, 8+5+5+32 (adjacent area number) * 5 (bit) * 1 (secondary) -5 (bit) * 1 (secondary)=178-5=can be saved
173bit。
More than analysis as can be seen that use above-mentioned improved method, reduced on the basis of the function of existing NLB algorithms and be
System expense is consumed to preceding to time slot, improves the forward direction time interval resource utilization rate of user.
The embodiment of the present invention solves asking for the forward direction time interval resource utilization rate that how to improve in cell mobile communication systems
In topic, particularly the time division way wireless telecommunication system being particularly suitable for use in based on data service, CDMA2000 series standards
EVDO strengthening systems.The embodiment of the present invention improves the forward direction time slot profit of user for the overhead of reduction EVDO strengthening systems
