Description
Technical field
The present invention relates to paging technique, relate in particular to a kind of paging method, base station, terminal and system.
Background technology
Fig. 1 is global system for mobile communications (GSM, Global System of Mobile communication) schematic diagram of system level frame structure, as shown in Figure 1, the wireless frame structure of GSM comprises five levels, be time slot, time division multiple access (TDMA, Time Division Multiple Access) frame, multi-frame, superframe and Hyperframe.Time slot is the elementary cell of physical channel; Tdma frame is made up of 8 time slots, is the elementary cell that occupies carrier frequency bandwidth, and each carrier frequency has 8 time slots; Multi-frame has two types: the multi-frame that (1) is made up of 26 tdma frames, this multi-frame is for Traffic Channel (TCH, Traffic Channel), slow associated control channel (SACCH, Slow Associated Control Channel) and Fast Associated Control Channel (FACCH, Fast Associated Control Channel); (2) multi-frame being formed by 51 tdma frames, this multi-frame is for Broadcast Control Channel (BCCH, Broadcast Control Channel), Common Control Channel (CCCH, Common Control Channel) and Separate Dedicated Control Channel (SDCCH, Stand-Alone Dedicated Control Channel); Superframe is the tdma frame of coherent 51 × 26, is made up of the multi-frame of 51 26 frames or the multi-frame of 26 51 frames; Hyperframe is made up of 2048 superframes.
Each superframe is made up of multi-frame again.Multi-frame is divided into two types.The multi-frame of 26 frames: it comprises 26 tdma frames, continues duration 120ms.This multi-frame is used for carrying TCH (SACCH and FACCH).The multi-frame of 51 frames: it comprises 51 tdma frames, continues duration 3060/13ms.This multi-frame is used for carrying BCCH and CCCH.
The existing Access granted Channel AGCH of CCCH (AGCH, Access Grant Channel) has again paging channel (PCH, Paging Channel).BS_AG_BLKS_RES is Access granted Channel AGCH reserved block number, therefore in network, must be set in CCCH channel massage piece number and have how many to be that reservation is special to Access granted Channel AGCH.In order to allow travelling carriage know this configuration information, in the configuration messages of each community, to comprise BS_AG_BLKS_RES parameter.
Paging channel belongs to the one of Common Control Channel (CCCH), for ICQ travelling carriage (MS, Mobile Station), belongs to down channel, and for point-to-multipoint circulation way, it is made up of 2～9 51 multi-frames.
When network is received after the channel request that the MS under idle pulley sends, need assigned with dedicated channel (SDCCH) according to this request, AGCH, according to the description of this assignment (divide the description of channel and the parameter of access), broadcasts to all travelling carriages.AGCH belongs to the one of Common Control Channel (CCCH), belongs to down channel, for point-to-multipoint circulation way.
B parameter S_AG_BLKS_RES has specified the piece number of distributing to AGCH, and remaining so to the piece number of PCH channel is (9-BS_AG_BLKS_RES).The corresponding paging subchannel of each piece, waits for that in same paging subchannel the customer group of beep-page message is called as a paging group.
BS_PA_MFRMS is the multi-frame number of paging channel, refers to a circulation using how many multi-frames as paging channel, and in fact this parameter has been determined a paging channel is divided into how many paging subchannels.BS_PA_MFRMS is larger, the paging number of subchannels of community is also more, the corresponding number of users that belongs to each paging subchannel is fewer, therefore the bearing capacity of paging channel is strengthened (not increase of the capacity of paging channel in theory, the buffer that just cushions beep-page message in each BTS is increased, make beep-page message send density in time with space on more even).But the acquisition of above-mentioned advantage is what to sacrifice the average delay of beep-page message on wireless channel be cost, BS_PA_MFRMS gets over ambassador's beep-page message and increases in the time delay of space segment, and the average service performance of system reduces.Visible, BS_PA_MFRMS is an important parameter of the network optimization.In the time that BS_PA_MFRMS gets maximum 9, can obtain maximum paging cycle and be about 2102ms, in the time that BS_PA_MFRMS gets minimum value 1, can obtain minimum paging cycle and be about 467ms.No matter BS_PA_MFRMS value is much, the capacity of paging channel does not increase in theory, because available paging number of subchannels is constant in the unit interval, and in community, all users need to use identical paging cycle.
If can increase paging cycle, can make terminal elongated in the time interval of twice monitoring seek channel, and if terminal enters resting state during twice monitoring seek channel, can reach the object of saves energy.Regrettably, there is no at present related art scheme can be for reference.

Embodiment
Basic thought of the present invention is: base station produces the pseudo-random number sequence identical with terminal, and in the time determining that paging group under described terminal arrives, peek from pseudo-random number sequence in the mode identical with terminal, and judge that got number is while setting number, in paging channel corresponding to described paging group, send the beep-page message for described terminal, accordingly, terminal paging receiving message in paging channel.
For making the object, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
The problem that the technical program need to solve is in the situation that not changing existing gsm system hardware and protocol infrastructure, to make terminal increase paging cycle.Terminal just can be closed hardware module and be entered resting state between the time interval of twice monitoring seek channel like this, to reach the object of saves energy.
Below the paging technique of gsm system is briefly described.
Paging grouping is base station controller (BSC, Base Station Controller) determine the paging group under it according to the international mobile subscriber identity in beep-page message (IMSI, International Mobile Subscriber Identification Number).Thereby issuing page message.Gsm system is support 9 × 9 totally 81 paging groups at most, that is to say that MS is divided at most 81 groups from paging group angle.All waiting at the MS of a special paging block is called in same paging group.Available paging block number × BS_PA_MFRMS in=mono-51TDMA frame multi-frame of paging group (PAGING GROUP) number.Wherein, the multi-frame number that BS PA MFRMS is paging channel, refers to a circulation using how many multi-frames as paging channel, and in fact this parameter has been determined a paging channel is divided into how many paging subchannels.
The number of paging group may be calculated: (9-BS_AG_BLKS_RES) × BS_PA_MFRMS.In a paging subchannel, can carry out paging by IMSI or TMSI or both modes of combination.Be specially 1) in 4 tdma frames, use 2 ISMI to carry out paging; 2) in 4 tdma frames, use 4 TMSI to carry out paging; 3) in 4 tdma frames, use 1 IMSI and 2 TMSI to carry out paging.
IMSI is by Mobile Country Code MCC (MCC, Mobile Country Code), mobile network No. (MNC, Mobile Network Code) and mobile identification number (MSIN, Mobile Subscriber Identification Number) composition.Length is 8 bytes.
Temporary mobile subscriber identity (TMSI, Temporary Mobile Subscriber Identity) by VLR Visitor Location Register (VLR, Visitor Location Register) be the identification information that visiting mobile subscriber distributes after authentication success, only in this VLR compass of competency, replace IMSI Interim use in interface aloft, and mutually corresponding with IMSI.Length is 4 bytes.Because IMSI length is 8 bytes, and TMSI length is 4 bytes, therefore the paging channel of air interface, in the time using the paging of IMSI mode, can only comprise two IMSI numbers in paging request message, and while using the paging of TMSI mode, in paging request message, can comprise four TMSI.Therefore, use IMSI mode paging meeting to cause the load of paging channel to double.
Each mobile subscriber (being corresponding each IMSI) belongs to a paging group (about the calculating of paging group is referring to GSM standard 05.02), and computational methods are X=(IMSI mod 1000) mod (paging group number).The corresponding paging subchannel of each paging group in each community, travelling carriage calculates the paging group under it according to the IMSI of self.Also just calculated the position of the paging subchannel that belongs to this paging group.Travelling carriage is only monitored the information of the paging subchannel belonging to and is ignored the information of other paging subchannels.Close hardware module to save electric energy at other paging subchannel duration of works.
The air interface paging message of GSM network is made up of core net CS paging message and core network packet-domain beep-page message.
After MSC obtains the current residing Location Area Identity LACOD of MS from VLR, all BSC to this lane place are sent to beep-page message PAGING.BSC receives after beep-page message, sends paging command message-PAGINGCOMMAND to all communities that belong to this lane place under this BSC.When receive after paging command base station, by sending paging request message PAGINGREQUEST on the paging subchannel of this IMSI place paging group at wireless channel, in this message, carry paged user's IMSI or TMSI.MS is receiving after paging request message, distributes standalone dedicated control channel SDCCH by Random Access Channel RACH request.BSC confirm base station activation after required SDCCH channel, at access permission channel AGC H by immediate assignment message IMASS by this SDCCH channel assignment to travelling carriage.Travelling carriage uses this SDCCH channel to send page-response message PAGRES.PAGRES message is transmitted to MSC by BSC, completes once successfully radio call.According to network settings, if MSC does not receive PAGRES message in second sending T after PAGING message, MSC can send one time PAGING message again, if T does not still receive PAGRES message in second, this time radio call failure, meanwhile, the recorded announcement that MSC will send called subscriber " temporarily can not connect " to calling subscriber.
Fig. 2 is the flow chart of the paging method of the embodiment of the present invention, and as shown in Figure 2, paging method of the present invention comprises the following steps:
Base station is used the IMSI number of certain travelling carriage to produce the pseudo random number integer sequence of span for [0, x] as random number seed.(except IMSI, also can produce pseudo-random number sequence, such as TMSI or MSISDN etc. by the parameter that other base station side and end side are known altogether).
In the present invention, by the length of pseudo random number integer sequence is set, setting terminal is monitored the cycle of paging subchannel, thereby it is long as much as possible to make terminal without communication service in the situation that, monitor cycle of paging subchannel, thereby reaches the object of power and energy saving.
It is the pseudo random number integer sequence of [0, x] that terminal is used the IMSI number of self to produce span as random number seed.(except IMSI, also can produce pseudo-random number sequence, such as TMSI or MSISDN etc. by the parameter that other base station side and end side are known altogether).Requiring base station and terminal must use identical pseudo random number to produce algorithm, is also that the pseudo-random number sequence that terminal and base station produce is identical.
The paging group that user belongs to is calculated according to formula X=(IMSI mod 1000) mod (paging group number) in base station.Wherein, the international mobile subscriber identity that IMSI is described terminal, mod represents modulo operation.
Terminal calculates according to formula X=(IMSI mod 1000) mod (paging group number) paging group that user belongs to.Wherein, the international mobile subscriber identity that IMSI is described terminal, mod represents modulo operation.
In the present invention, owing to generally comprising 0 in pseudo random number integer sequence, therefore, using 0 as setting number.
When base station access by terminal and complete on VLR after registration, when the paging group under terminal arrives, base station and terminal are peeked in an identical manner from aforesaid pseudo random number integer sequence.Base station and terminal are by order from front to back or from aforementioned pseudo random number integer sequence, peek successively to front sequence from rear.
When to X paging subchannel, base station judges whether the number now taking out from pseudo random number integer sequence is 0, if 0 and now have a beep-page message to user, base station just sends beep-page message on this paging subchannel so, otherwise this beep-page message is stored in message queue and wouldn't be sent.
When base station access by terminal and complete on VLR after registration, when the paging group under terminal arrives, base station and terminal are peeked in an identical manner from aforesaid pseudo random number integer sequence.Base station and terminal are by order from front to back or from aforementioned pseudo random number integer sequence, peek successively to front sequence from rear.
When to X paging subchannel, whether the integer that terminal judges now obtains from pseudo random number integer sequence is 0, and 0 terminal is attempted paging receiving message on this paging subchannel if.Otherwise terminal is according to the position calculation time point of paging receiving message next time that occurs 0 in pseudo random number integer sequence next time, enter park mode after setting timer, in the time that timer finishes, recover and attempt paging receiving message.
In the present invention, base station can further expand by random number span the paging cycle of all terminals.Terminal can be calculated the time point of paging receiving message next time according to 0 position occurring in pseudo-random number sequence, thereby at the particular point in time monitoring seek channel of reviving, in the time not needing monitoring seek channel, proceed to resting state, so just can make terminal power saving.
