Description
Technical field
The present invention relates to a kind of wireless communication technology, relate in particular to wireless channel distribution method.
Background technology
GSM strengthens data rate (Enhanced Data rates for GSM Evalution, abbreviation Edge) technology is the data enhancement techniques of GSM/GPRS network, 3 times of data movement capacities to GPRS can be provided, be commonly called the 2.75G technology between 2.5G and 3G.
In the present invention, will support the terminal of Edge to become the Edge terminal, will support GPRS and do not support the terminal of Edge to be called the GPRS terminal.
Support at the same time in the mobile communication system of GPRS and Edge how network gives GPRS terminal and Edge terminal with radio channel allocation is a key factor that has influence on wireless resource utility efficiency and network service quality.Existing radio channel allocation mode has two kinds: fixed allocation mode and dynamic assignment mode.
The fixed allocation mode is meant in a sub-district, gives GPRS terminal and Edge terminal with the wireless channel in the sub-district by the method fixed configurations of data configuration.The use pattern of wireless channel does not allow dynamic change in the sub-district in the running of sub-district.Wireless channel data configuration (being the ratio of GPRS terminal wireless channel and Edge terminal traffic channel) before the cell initialization is to determine according to certain professional historical data and traffic model.There is the deficiency of following two aspects in this method of salary distribution:
(1) with regard to whole network, the Edge traffic carrying capacity changed between its operating period, and this certainly will require network based traffic volume measurement numeral regularly or aperiodically to adjust the traffic channel data configuration.And at the business introducing initial stage, the Edge traffic carrying capacity is difficult to accurately estimate, adopts fixed allocation mode network to be difficult to an amount of wireless channel of Edge traffic assignments, and certain waste of radio resources can hardly be avoided.
(2) owing to the variation of terminal mobility, time and cell environment, network is in running, and the ratio of the ratio of gprs service amount and Edge traffic carrying capacity is dynamic change, and this variation also may be very violent.May occur following two kinds of situations in the network operation process: the gprs service amount peaks and takes place congested, and Edge traffic carrying capacity situation seldom, this means is having under the situation of wireless channel idle, still have some GPRS terminals to can not get service, network call loss height, poor performance, channel utilization is low; Another kind of situation is that the Edge traffic carrying capacity is bigger, the network fixed allocation gives its resource not enough, and this moment, the gprs service amount was little, distribute to the channel idle of GPRS terminal, this means is having under the situation of wireless channel idle, network can not provide the Edge business of higher rate for more terminal, causes network performance poor so equally, and wireless resource utility efficiency is low.
Existing another kind of radio channel allocation mode---the attitude method of salary distribution, the wireless channel that is meant the sub-district is configured to gprs service and the Edge service dynamic is shared.Dynamically the allocation criteria of shared wireless channel is: under the situation of no idle Radio Resource, gprs service and Edge business can shared same wireless channels.This method of salary distribution when ratio of gprs service and Edge business changes in the sub-district, can provide certain cushioning effect with respect to a kind of method of salary distribution in front, thereby can improve utilization ratio of wireless resources on certain program.But still there is following deficiency in this method of salary distribution:
(1) when Edge terminal and the shared same wireless channel of GPRS terminal, and the Edge terminal is downloaded, when the GPRS terminal is uploaded simultaneously, can cause the throughput of Edge terminal to reduce about 70% because of influenced by the GPRS terminal.Main cause is as follows: terminal is determined multiplexing order by detecting uplink state flags (UplinkState Flag is called for short USF) in advance, determines which terminal this takes turns at uplink data sending.If carrying out Edge 8 phase place phase-shift keyings (8Phase Shift Keying, abbreviation 8PSK) transfer of data, when the GPRS terminal needs transmitting uplink data, must in current Edge transmission transfer of data of carrying out, detect USF in advance, but the GPRS terminal can't be decoded, therefore this moment, Edge can only adopt Gaussian Minimum Shift-frequency Keying (Gaussian Minimum Shift Keying, abbreviation GMSK) coded system sends data, can accurately detect USF to guarantee the GPRS terminal.In the Edge technology, the code efficiency of 8PSK is higher than the code efficiency of GMSK, so during the shared same wireless channel of Edge terminal and GPRS terminal, and the Edge terminal is downloaded, can influence the descending performance of Edge when the GPRS terminal is uploaded simultaneously.
Summary of the invention

Embodiment
For the system wireless level of resources utilization is provided, the reduction of the Edge terminal downloads speed of avoiding the shared same wireless channel of Edge terminal and GPRS terminal simultaneously and causing, in the present invention, wireless channel comprises three kinds: Edge terminal priority channel, GPRS terminal priority channel and shared channel.
Edge terminal priority channel is preferably the Edge terminal channel resource is provided; Avoid the shared same channel of Edge terminal and GPRS terminal, at any time, use the terminal of same Edge terminal priority channel to be the Edge terminal or to be the GPRS terminal; And when not having the Edge terminal to use, Edge terminal priority channel can be distributed to the GPRS terminal and use.
GPRS terminal priority channel is preferably the GPRS terminal channel resource is provided; Avoid the shared same channel of Edge terminal and GPRS terminal at any time, use the terminal of same GPRS terminal priority channel to be the GPRS terminal or to be the Edge terminal; And when not having the GPRS terminal to use, GPRS terminal priority channel can be distributed to the Edge terminal and use.
Shared channel provides channel resource for GPRS terminal and Edge terminal, and in shared channel, the GPRS terminal is enjoyed identical priority with the Edge terminal.
At network side, the number that can determine all types of channels according to the user situation and the network condition of reality, and according to the difference of actual conditions, can be any two types with channel configuration also, for example, be Edge terminal priority channel and shared channel with channel configuration; Perhaps be Edge terminal priority channel and GPRS terminal priority channel with channel configuration.
The radio channel allocation equipment of network side judges that according to the ability information of terminal terminal still is the GPRS terminal for the Edge terminal after receiving the Packet data service request that terminal sends.
The existing mode of obtaining terminal capability has multiple.For example, after starting up of terminal is attached on the GPRS/Edge network, the Serving GPRS Support Node of network side (Serving GPRS Supporting Node is called for short SGSN) will obtain the also ability information of storage terminal, and this ability information comprises whether terminal supports Edge; Radio channel allocation equipment can obtain the ability information of terminal from SGSN after the Packet data service request that receives the terminal transmission, thereby judges that terminal still is the GPRS terminal for the Edge terminal.The present invention to the method for obtaining terminal capability without limits, as long as channel assigning device can be before being the terminal distribution channel, the ability information of obtaining this terminal gets final product.
Embodiment one
In the present embodiment, wireless channel is configured to two kinds: Edge terminal priority channel and GPRS terminal priority channel.
As shown in Figure 1, for the present embodiment flow chart, comprise the steps:
Edge terminal priority channel is used to be preferably the Edge terminal provides channel resource, and at any time, and the terminal by this channel transmission data is the Edge terminal, perhaps is the GPRS terminal; GPRS terminal priority channel is used to be preferably the GPRS terminal provides channel resource, and at any time, and the terminal by this channel transmission data is the Edge terminal, perhaps is the GPRS terminal;
As shown in Figure 2, the flow chart for step 130 comprises the steps:
The access request of step 135, refusal terminal;
As shown in Figure 3, during for Edge terminal distribution wireless channel, carry out following steps:
Step 131A, judgement treat whether there is the channel that can distribute in the Edge terminal priority channel, if exist, and execution in step 132A, otherwise, execution in step 133A;
Step 132A, be Edge terminal distribution Edge terminal priority channel, execution in step 136A;
Step 133A, judge in the GPRS terminal priority channel whether have the channel that can distribute, if exist, execution in step 134A otherwise, execution in step 135A;
Step 134A, be Edge terminal distribution GPRS terminal priority channel, execution in step 136A;
The access request of step 135A, refusal Edge terminal;
Step 136A, end.
For the step and the said process of GPRS terminal distribution wireless channel similar, judge to treat whether there is the channel that can distribute in the GPRS terminal priority channel earlier, if exist, be the preferential channel of GPRS terminal distribution GPRS terminal, otherwise, judging in the Edge terminal priority channel whether have the channel that can distribute, if exist, then is GPRS terminal distribution Edge terminal priority channel; Otherwise, do not have the wireless channel that can distribute, the access request of refusal terminal.
For each channel, operating position has three kinds: idle, Edge terminal is used, the GPRS terminal is used.The bearing capacity of each channel is limited, under back two kinds of situations, also can specifically be divided into number of terminals and reach the maximum number of terminals that channel can carry, and for reaching two kinds of situations of maximum number of terminals.
When whether having the channel that can distribute in judging channel terminal priority channel to be allocated, be preferably the channel of terminal distribution free time, if there is not an idle channel, whether the channel of then judging existing terminal again has and can distribute.
As shown in Figure 4, when terminal is the Edge terminal, judge whether to exist Edge terminal priority channel, and be that the step of Edge terminal distribution Edge terminal priority channel can comprise when existing:
In said method, when being this terminal priority channel of terminal distribution, be preferably this terminal priority channel of the terminal distribution free time of channel to be allocated; If do not have idlely,, therefore, another type terminals is moved another type terminals priority channel because this type of channel should priority allocation be given the terminal identical with this terminal type; If the type of the terminal of this type of channel of use is all identical with this terminal type, so then be the channel of terminal distribution number of terminals less than the maximum number of terminals that can carry, the terminal identical that be as if all these terminal priority channels carryings with this terminal type, and the terminal number average has reached maximum number of terminals, so then do not have this terminal priority channel that can distribute, need continue to judge whether the other types channel that can distribute.The method has guaranteed preferentially to give the terminal with priority with channel allocation, is equally applicable to be GPRS terminal distribution GPRS terminal priority channel.
The load that also can increase network of moving owing to transfer of data, therefore when being the preferential channel of this terminal of terminal distribution, can not have under the situation of idle channel yet, judged whether that earlier number of terminals is less than maximum number of terminals, and use the terminal of channel to be channel with priority endpoint, think that GPRS terminal distribution GPRS terminal priority channel is an example, step as shown in Figure 5:
Step 1316B, the transfer of data of whole Edge terminals of GPRS terminal priority channel carrying is moved Edge terminal priority channel, and will move the idle channel allocation in back and give GPRS terminal, execution in step 1318B;
Above-mentioned distribution method has also been avoided moving of transfer of data as far as possible under the situation of avoiding Edge terminal and GPRS terminal shared channel, when the channel that can distribute, allow terminal and other terminal of the same type carry out multiplexing earlier.
When the channel terminal priority channel to be allocated that does not have to distribute, need to continue execution in step 133, judge whether the preferential channel of another type terminals that can distribute.The channel preferential with being this terminal of terminal distribution is similar, can be preferably this terminal priority channel of the terminal distribution free time of channel to be allocated; If do not have idlely, judge whether that then carrying terminal and number of terminals of the same type is another type terminals priority channel that reaches maximum number of terminals, if having, it then is this channel of terminal distribution, otherwise, do not have to distribute to another type terminals of terminal, the access request of refusal terminal.Because another type terminals priority channel answers priority allocation to give another type identical terminal, therefore, another type terminals is not moved.As shown in Figure 6, when being Edge terminal distribution GPRS channel, can carry out following steps:
Step 1332, be the GPRS terminal priority channel of Edge terminal distribution free time, execution in step 1336;
In addition, because GPRS terminal priority channel is preferably the GPRS terminal channel resource is provided, therefore when for Edge terminal distribution channel, can judge whether Edge terminal use GPRS terminal priority channel earlier, and number of terminals is less than maximum number of terminals, if have, then be this channel of Edge terminal distribution, as if the idle GPRS terminal priority channel that does not judge whether again to distribute.Like this, the Edge terminal that takies GPRS terminal priority channel can be concentrated on a channel as far as possible,, and also can reduce data-moving indirectly with the use of assurance GPRS terminal.
Present embodiment can be avoided Edge terminal and the shared same wireless channel of GPRS terminal simultaneously by the utilization ratio that two channels with priority can effectively improve unlimited resources is set.
Embodiment two
In the present embodiment, wireless channel is configured to two kinds: Edge terminal priority channel and shared channel.
As shown in Figure 7, for the present embodiment flow chart, comprise the steps:
Edge terminal priority channel is used to be preferably the Edge terminal provides channel resource, and at any time, and the terminal by the type channel transmission data is the Edge terminal or is the GPRS terminal; Shared channel is used to Edge terminal and GPRS terminal that channel resource is provided;
As shown in Figure 8, the flow chart for step 230 comprises:
Step 2322, judge whether to exist the shared channel that can distribute, if exist, execution in step 2323, otherwise, execution in step 234;
The access request of step 234, refusal terminal;
Wherein, when terminal is the Edge terminal, judges whether there is Edge terminal priority channel and be that the method for Edge terminal distribution is identical with embodiment one when existing.Shared channel has four kinds of operating positions: free time, the use of Edge terminal, the use of GPRS terminal and Edge terminal and GPRS terminal are shared.Because in shared channel, the Edge terminal has identical priority with the GPRS terminal, be that Edge terminal and GPRS terminal distribution shared channel method are similar therefore.When distributing shared channel, the shared channel of priority allocation free time if do not have idlely, then judges whether the shared channel of number of terminals less than maximum number of terminals.Think that below Edge terminal distribution shared channel is the method that example illustrates distribution shared channel of the present invention, as shown in Figure 9, this method may further comprise the steps:
Step 260, judge whether idle shared channel, if having, execution in step 261, otherwise, execution in step 262;
Step 261, be the shared channel of Edge terminal distribution free time, execution in step 265;
Step 262, judge whether there be the channel of number of terminals in the shared channel less than maximum number of terminals, if exist, execution in step 263, otherwise, execution in step 264;
Step 263, be shared channel of Edge terminal distribution, with other Edge terminal and/or GPRS terminal on this channel, carry out multiplexing, execution in step 265;
Step 264, there is not the shared channel that can distribute, the access request of refusal Edge terminal;
Step 265, end.
For the GPRS terminal, be with the difference of Edge terminal, when not having the shared channel that can distribute, also need continue to judge whether the Edge terminal priority channel that can distribute, for the method for GPRS terminal distribution Edge terminal priority channel identical with embodiment one.
In shared channel, Edge terminal and GPRS terminal may occur and use the situation of same channel, in this case, the situation that Edge terminal transmission speed reduces still can appear, in order to reduce the generation of this situation as far as possible, be that terminal distribution is during the shared channel of bearer data transmission, terminal distribution that can be as far as possible that type is identical is to same shared channel, below a GPRS terminal be the method that example describes the shared channel that uses for the existing terminal of terminal distribution of the present invention, as shown in figure 10, comprise the steps:
Step 2621, judge whether to exist the transfer of data of only having carried the GPRS terminal and number of terminals shared channel less than maximum number of terminals, if exist, execution in step 2622, otherwise, execution in step 2623;
Step 2622, only carried the shared channel of GPRS terminal data transmission for one of GPRS terminal distribution, it is multiplexing that this GPRS terminal and other GPRS terminals are carried out at this channel, execution in step 2628;
Step 2623, judge whether to exist and carried GPRS terminal and Edge terminal and number of terminals shared channel, if having execution in step 2624, otherwise execution in step 2625 less than maximum number of terminals;
Step 2624, carried the transfer of data shared channel of GPRS terminal and Edge terminal for one of GPRS terminal distribution, this GPRS terminal and other GPRS terminals and Edge terminal are carried out multiplexing at this channel, execution in step 2628;
Step 2625, judge whether to exist and only carried Edge terminal and number of terminals shared channel less than maximum number of terminals, if exist, execution in step 2626, otherwise, execution in step 2627;
Step 2626, only carried the shared channel of Edge terminal for one of GPRS terminal distribution, this GPRS terminal and other Edge terminals are carried out multiplexing at this channel, execution in step 2628;
Step 2627, do not have to be the shared channel of GPRS terminal distribution, continue to judge whether to be the Edge terminal priority channel of its distribution;
Step 2628, end.
When terminal is Edge, judge whether to distribute the shared channel that has only carried the Edge terminal earlier, if can, then distribute, otherwise judge whether to distribute the shared channel that has carried Edge user and GPRS terminal again, if can, then distribute, otherwise judge whether to be dispensed to the shared channel that has carried the GPRS terminal, if can, then distribute, otherwise, there is not the shared channel that can distribute, the access request of refusal Edge terminal.
Can be set to GPRS terminal priority channel and shared channel by channel, method for channel allocation is similar.
Embodiment three
