Abstract
The method includes following steps: first, a user ID is defined for each user, and different class user has different user ID; 'user class' message is stored in home location register( HLR); when mobile switch center (MSC)/ visit location register(VLR) renews location, it receives the user data transmitted from the HLR; HLR transmits the signaling to MSC through MAP; MSC sends it to base station controller (BSC); at the condition of closing dynamic half rate function, BSC distributes channel based on channel service priority table transmitted from MSC; at the condition of opening dynamic half rate, BSC modifies the channel service priority table for all users into half rate priority; based on this, the half rate channels are distributed to low end user, and full speed channels are distributed to high end user.
Description
Technical field:
The present invention relates to a kind of wireless network resource and distribute, be meant especially when a kind of user's difference at different brackets is carried out channel allocation, use the method for full rate/half-rate channel.
Principle according to " priority difference, the channel coding method difference of distribution " is user's allocation of network resources.
Background technology:
At present, along with the aggravation of mobile communication market competition, the means that mobile operator all takes constantly to reduce rate keep the stable of existing customer to strive for simultaneously Adding User.The consuming capacity that the following mediation of post and telecommunication tariff improves day by day stimulates the quick increase of communication user and the continuous increase of unit user traffic.When the growth of network capacity can't be satisfied the growth of communication user and unit user traffic, will cause the obstruction of communication.Under this background, operator takes to have reduced service quality to a certain extent by using the half rate encoded mode to improve network capacity fast one after another.This application is used when a large amount of burst service takes place during festivals or holidays especially.
The half rate function is the function of pan-European digital cellular mobile communcations system (GSM) PHASE 2, and it is encoded by compressed voice, makes speech encoding rate drop to 6.5kb/s from the 13kb/s of full rate, thereby saves the air traffic channel resource.Full rate is carried out segmentation with the digital voice of 64Kbit/S, every section 20ms, and then carry out hybrid coding, 260 bits weaved in the speech of every 20ms, be that bit rate is 260bit/20ms=13Kbit/S, the bit rate of every like this road speech is reduced to 13Kbit/S from 64Kbit/S.Half rate is weaved into 130 bits with the speech of 20ms, and promptly bit rate is 130/20ms=6.5Kbit/S.
The application process of half-rate channel is divided into static half rate and dynamic two kinds of methods of half rate:
Static half rate is used: after base station controller (BSC) is received the CHANNEL REQUEST message of MSC, according to the CHANNEL TYPE in this message, base station controller (BSC) obtains the bearing capacity (BEARER CAPABILITY) of portable terminal, if portable terminal is supported dual rate (it is preferential preferential with support dual rate/half rate to comprise support dual rate/full rate), then base station controller (BSC) will activate half-rate channel and distribute to portable terminal, if portable terminal is only supported full rate, then base station controller (BSC) will activate full speed channel and distribute to portable terminal.
Dynamically half rate is used: after base station controller (BSC) is received the CHANNEL REQUEST message of mobile switching centre (MSC), according to the CHANNEL TYPE in this message, base station controller (BSC) obtains the bearing capacity (BEARER CAPABILITY) of portable terminal.When using dynamic half rate to use, (BSC) is provided with thresholding at base station controller.When Internet resources redundancy during less than this thresholding, if portable terminal is supported dual rate (it is preferential preferential with support dual rate/half rate to comprise support dual rate/full rate), then base station controller (BSC) will activate half-rate channel and distribute to portable terminal, if portable terminal is only supported full rate, then base station controller (BSC) will activate full speed channel and distribute to portable terminal.When Internet resources redundancy during greater than this thresholding, if portable terminal supports dual rate and full rate is preferential or portable terminal is only supported full rate, then base station controller (BSC) will activate full speed channel and distribute to portable terminal, if portable terminal support dual rate and half rate are preferential, then base station controller (BSC) will activate half-rate channel and distribute to portable terminal.
The concrete method of using is: when connection of mobile terminal into network, pass through air interface, comprise Bearer capability information in hair family sign (SETUP) message on the portable terminal, in this message, comprised the support situation (radio channelrequirement) of portable terminal, specifically seen the following form the Traffic Channel code rate:

C) after the CHANNELREQUEST distribution of messages radio traffic channel of base station controller (BSC) according to mobile switching centre (MSC), base station controller (BSC) activates message (CHANNEL ACTIVATION) notice BTS by channel and carries out the channel activation, BTS finishes and sends channel activation identification message (CHANNELACTIVATION ACKNOWLEDGE) after channel activates, after BSC receives that channel activates identification message, by assignment commands (ASSIGNMENT COMMAND) notice portable terminal.
At present, can only decide the Traffic Channel of when using the half rate encoded mode, can't distribute according to user's grade according to the bearing capacity of network capacity.
Summary of the invention:
The purpose of this invention is to provide a kind of that radio channel allocation is relatedly with user property, the full rate/half-rate channel operational version of complete personalization can be provided at each user or brand.Promptly the principle according to " priority difference, the channel coding method difference of distribution " is user's allocation of network resources.Realization assurance high-end user is preferentially selected full speed channel, to obtain high-quality network service as far as possible.Guarantee low side user priority selection half-rate channel, to reduce network load to greatest extent.According to the regulation in ETSI 0902 (MAP2+) standard, class of subscriber can be ordinary, calling subscriber with priority, classifications such as test call, payphone, simultaneously, new self-defining class of subscriber can also be enabled as required by operator.
A kind of dual rate using method relevant with user property, may further comprise the steps: at first, be a user ID of each user definition (STYPE), different brackets user's user ID difference, " class of subscriber " information leaves in the Home Location Register (HLR), mobile switching centre (MSC)/when VLR Visitor Location Register (VLR) upgrades in the position, receive the user data that HLR transmits has wherein comprised this user ID of user.
1, the user is when call setup, by the bearing capacity report MSC of CALL SETUP message with terminal.
2, mobile switching centre (MSC) network element carries out software modification, channel rateand type parameter (i.e. the channel kind of Fen Peiing) in the CHANNEL REQUIRED message that the mobile switching centre (MSC) that realizes user visiting ground determines whether base station controller (BSC) is transmitted according to user's user ID and the terminal bearing capacity of receiving is made amendment, when user ID was high-end user, mobile switching centre (MSC) did not change channel rate and type parameter (i.e. the channel kind of Fen Peiing).When user ID during for low end subscriber, if portable terminal for only supporting full speed channel, mobile switching centre (MSC) does not change channel rate and type; If portable terminal is for supporting double speed rate channel and full speed channel preferential, then mobile switching centre (MSC) will change channel rate and type parameter (i.e. the channel kind of Fen Peiing), be revised as first and be chosen as the priority allocation half-rate channel, second is chosen as the distribution full speed channel.
3, mobile switching centre (MSC) will pass to base station controller (BSC) according to the amended channel rate of user ID and type by assignment request signaling on the A interface, and base station controller carries out the distribution of corresponding radio channel resource.
STYPE is the sign of user property, and high-end user and low end subscriber are with different signs.Pass to mobile switching centre (MSC) by MAP signaling (being positioned at the expansion area of MAP signaling) by Home Location Register (HLR), because Home Location Register (HLR) and mobile switching centre (MSC) all belong to the equipment of same producer, therefore particular user identifies the value of (STYPE) and can oneself define in the position of MAP signaling, be not particularly limited, if the equipment of different manufacturers, then need both sides to arrange in advance, present pan-European digital cellular mobile communcations system (GSM) standard does not have related constraint.After the MAP signaling is received by mobile switching centre (MSC),, when being retained in call setup, issues high-end user the channel services precedence table order (full speed channel is preferential) of network by mobile phone according to the definition of user ID (STYPE); Low end subscriber is then revised it is issued network when the call setup by mobile phone channel services precedence table order (it is preferential to be revised as half-rate channel).And then the channel services precedence table sent to base station controller (BSC).
For the high-end user of mobile phone terminal support full rate and half rate, base station controller (BSC) priority allocation full speed channel, when not having full speed channel, base station controller (BSC) will distribute half-rate channel; Only support the high-end user of full rate for mobile phone terminal, base station controller (BSC) distributes full speed channel, when no full speed channel, then can't call out; For the low end subscriber of mobile phone terminal support full rate and half rate, base station controller (BSC) distributes half-rate channel; Only support full rate to hang down end subscriber for mobile phone terminal, base station controller (BSC) distributes full speed channel, when no full speed channel, then can't call out.
Because current most mobile phones, surpass 19% mobile phone for supporting dual rate and full rate preferential (about 80%) in addition for only supporting full rate, support the preferential mobile phone of dual rate and half rate less than 1%.Therefore by above-mentioned change, realized that when network was busy, high-end user was preferentially selected full speed channel, the low side user priority is selected half-rate channel.
Embodiment:
Phase I:By loading patch in mobile switching centre (MSC), finish its channel services precedence table of low side user's modification, change first selective channel into half rate, second selective channel changes full rate into; High-end user still keeps first channel to be chosen as full rate, and second channel is chosen as half rate; Need manually to close dynamic half rate at base station controller (BSC), be implemented in the network peak hours/period and give high-end user priority allocation full rate, distribute half rate for the low side user priority at network busy hour.
Second stage:By loading patch, finish in mobile switching centre (MSC) to its channel services precedence table of low side user's modification, at the dynamic half rate employment mechanism of base station controller (BSC) modification in mobile switching centre (MSC) and base station controller (BSC).Realize opening half rate differentiation application function by the sub-district, during the sub-district half rate thresholding in not reaching base station controller (BSC) network element, set, all CU full speed channels, during the sub-district half rate thresholding in reaching base station controller (BSC) network element, set, low end subscriber distributes half-rate channel all the time, high-end user priority allocation full speed channel.
Original mechanism: the user issues network with its channel services table when call setup, is not opening under the dynamic half rate situation, and base station controller (BSC) is according to the priority allocated channel of channel in the channel services precedence table of sending out on the mobile phone.Opening under the dynamic half rate situation, it is preferential that base station controller is revised as half rate with all users' channel services precedence table, and distribute half-rate channel by this to the user.
New mechanism: the user issues network with its channel services table when call setup, define user class (high and low) with user ID (STYPE) in the Home Location Register (HLR), Home Location Register (HLR) is passed to mobile switching centre (MSC) by MAP layer signaling, mobile switching centre passes to base station controller (BSC) with it, under dynamic not unlatching situation of half rate function, base station controller passes the amended channel services precedence table allocated channel of coming according to mobile switching centre; Opening under the dynamic half rate situation, it is preferential that base station controller BSC is revised as half rate with all users' channel services precedence table, and distribute half-rate channel for the low side user priority by this, gives high-end user priority allocation full speed channel.
