S102, professional according to the first beep-page message update system message or initiation.

The executive agent of above step is the terminal of first sub-district.

In embodiments of the present invention, first base station can be evolution base station (evolved Node B; ENB), base-station (Base Station; BS), Node B, access point (access point) etc.First base station can also be a macro base station, medium-sized base station, or femto cell, for example Home eNodeB etc.First base station can provide communication to cover for specifically managing the zone.Term " sub-district (cell) " can be the overlay area of base station, and/or the overlay area of base station sub-system service, depends on the employed context of this term.First base station can be macrocell, Microcell (pico cell), femtocell sub-district (femto cell), and/or the sub-district of other type provides communication to cover.

In embodiments of the present invention, the terminal can be distributed in the whole wireless network, and each terminal can be static state or mobile.Terminal (terminal) can be subscriber equipment (user equipment; UE), for example: Wireless Telecom Equipment, handheld device (handheld), cordless telephone (cordless phone) etc.The terminal can with macro base station, pico base station, base stations such as femto base station communicate.

Base station under first sub-district is first base station, and first base station is used in first cell range, sending beep-page message, and first sub-district can be by interfered cell.

The terminal receives first Radio Resource of first beep-page message, can be the existing Radio Resource of system, and definite through coordinating between website by first base station; Perhaps; First Radio Resource can also be on the existing Radio Resource basis that is used for paging receiving message of system, to expand the extended wireless resource that obtains; The Radio Resource of this expansion can be definite through coordinating between website by first base station, also can be set according to paging resource interference situation or paging load situation by first base station.

Wherein, first base station can utilize X2 interface and other websites to coordinate to confirm first Radio Resource; First base station is also through third party device, for example: operation management maintain (Operation Administration and Maintenance; OAM) equipment etc. coordinates to confirm first Radio Resource with other websites.

For interference base station second base station of first base station, second Radio Resource that second beep-page message that send in the scope of second sub-district (interfered cell) first Radio Resource and second base station is positioned at can be different Radio Resource.

As a kind of possible implementation, first Radio Resource can be different time-domain resource with second Radio Resource, and specifically: second Radio Resource can be second paging frame (Paging Frame; PF), first Radio Resource can be first PF, and a PF is different with the 2nd PF; Perhaps, second Radio Resource can be second paging subframe (the Paging Occation; PO), first Radio Resource can be a PO, and a PO is different with the 2nd PO; Perhaps, second Radio Resource can comprise the second paging frame PF and the second paging subframe PO, and first Radio Resource comprises a PF and a PO, and the 2nd PF is different with a PF, and/or the 2nd PO is different with a PO.

At present, the PF that sends beep-page message is calculated according to SFN mod T=(T div N) * (UE_ID mod N) usually in first base station and second base station, and wherein, Mod () representes modulo operation, and div representes division arithmetic.System Frame Number (System Frame Number; When SFN) satisfying SFN mod T=(T div N) * (UE_ID mod N); Promptly; When SFN mod T=(T div N) * (UE_ID mod N) sets up; SFN is exactly the radio frame number of sending the PF place of beep-page message, and T representes discontinuous reception (the Discontinuous Reception at the terminal of first sub-district or second sub-district; DRX) cycle, and N:min (T, nB), nB can be pre-configured by first base station or second base station; For example: nB=4T, 2T, T; T/2, T/4, T/8; T/16, T/32, UE_ID are that the identify label number at the terminal of first sub-district or second sub-district (specifically can be sign international mobile subscriber identity (International Mobile Subscriber Identification Number; IMSI) with 1024 mould).Accordingly, the PF of paging receiving message is also calculated at the terminal of the terminal of first sub-district and second sub-district according to SFN mod T=(T div N) * (UE_ID mod N).Can find out that from SFN mod T=(T div N) * (UE_ID mod N) for example: when nB=T/4, PF is 4 integral multiple position at SFN, promptly the terminal of the terminal of first sub-district and second sub-district is a paging receiving message on the PF of 4 integral multiple at SFN all.Therefore, first base station can be through carrying out conversion to SFN mod T=(T div N) * (UE_ID mod N), and the terminal that makes first sub-district is to receive first beep-page message on the PF of 4 integral multiple at non-SFN.Promptly first base station can be through carrying out conversion to SFN mod T=(T div N) * (UE_ID mod N); Make terminal paging receiving message on different PF of the terminal and second sub-district of first sub-district; Perhaps; Conversion also can be carried out to SFN mod T=(T div N) * (UE_ID mod N) in second base station; But need to guarantee that the PF that finally confirms in first base station and second base station is different, the PF of terminal paging receiving message of terminal and second sub-district of first sub-district is staggered, thereby avoid the beep-page message conflict in the radio frames rank.

At present; First base station and the second base station specific paging subframe PO place in paging frame PF sends beep-page message; Therefore, except the PF of the terminal paging receiving message of the above-mentioned terminal that makes first sub-district and second sub-district staggers, the PO of terminal paging receiving message of terminal and second sub-district of first sub-district is staggered; Specifically can change first base station and send the PO position of beep-page message originally; Perhaps, can also change the PO position that first base station and second base station are sent beep-page message originally simultaneously, but need guarantee that in this case the PO position that first base station and second base station change staggers; Thereby make terminal paging receiving message on the PO different of first sub-district, realize that the terminal of second sub-district and the terminal of first sub-district avoid the beep-page message conflict in paging subframe rank with the terminal of second sub-district.

First base station and second base station can consult to send separately the PF and/or the PO of beep-page message in advance.Message can be in advance sent to the terminal in first base station or second base station, informs terminal paging receiving message on the PF of appointment and/or PO, perhaps, is stored the PF and/or the PO of paging receiving message in advance by the terminal.

As another kind of possible implementation; First Radio Resource can be different frequency domain resource with second Radio Resource, and for example: first Radio Resource and second Radio Resource can be that different physical layer wireless resource block is (like Physical Resource Block (Physical Resource Block; PRB)); First base station can take one section PRB; Second beep-page message or the non-transmitted power can be sent with low-power in second base station on the PRB of correspondence, the data field information or the control domain information of beep-page message is sent in optional being used to of physical layer wireless resource block here.

In addition, first Radio Resource can also be different running time-frequency resources with second Radio Resource, promptly; First Radio Resource promptly is different time-domain resource with second Radio Resource; Be again different frequency domain resource, can repeat no more referring to the description of present embodiment front in detail.

The paging method that the embodiment of the invention provides; By the Radio Resource at interfered cell terminal paging receiving message place; Confirm, perhaps be the Radio Resource of expansion through coordination between website through base station under the interfered cell; Do not take the Radio Resource of the terminal receiving paging signal of interfered cell when making, guarantee the normal paging service at interfered cell terminal, avoid by the Radio Resource conflict of the terminal receiving paging signal of the terminal of interfered cell and interfered cell by the terminal receiving paging signal of interfered cell.

Fig. 2 is the flow chart of another embodiment of paging method provided by the invention, and is as shown in Figure 2, and this method comprises:

S201, first base station are through coordinating to confirm to be used to send first Radio Resource of first beep-page message between website, perhaps first Radio Resource that is used to send first beep-page message is confirmed as with the Radio Resource of expansion in first base station;

Said first beep-page message is sent in S202, first base station in first cell range on said first Radio Resource.

Wherein, first base station is the base station under first sub-district, and first sub-district can be by interfered cell.

First Radio Resource of first beep-page message is sent in first base station, can be the existing Radio Resource of system, and definite through coordinating between website by first base station; Perhaps; First Radio Resource can also be on the existing Radio Resource basis that is used for paging receiving message of system, to expand the extended wireless resource that obtains; The Radio Resource of this expansion can be definite through coordinating between website by first base station, also can be set according to paging resource interference situation or paging load situation by first base station.

First base station can utilize X2 interface and other websites to hold consultation to confirm first Radio Resource; First Radio Resource can also be coordinated to confirm through third party's website and other websites in first base station.

As a kind of possible implementation, first Radio Resource can be different time-domain resource with second Radio Resource, and specifically: second Radio Resource can be the second paging frame PF, and first Radio Resource can be first PF, and a PF is different with the 2nd PF; Perhaps, second Radio Resource can be the second paging subframe PO, and first Radio Resource can be a PO, and a PO is different with the 2nd PO; Perhaps, second Radio Resource can comprise the second paging frame PF and the second paging subframe PO, and first Radio Resource comprises a PF and a PO, and the 2nd PF is different with a PF, and/or the 2nd PO is different with a PO.

At present, the PF that sends beep-page message is calculated according to SFN mod T=(T div N) * (UE_ID mod N) usually in first base station and second base station, and wherein, Mod () representes modulo operation, and div representes division arithmetic.SFN is a System Frame Number, if SFN mod T=(T div N) * (UE_ID mod N) sets up, then SFN is the sequence number at the PF place of transmission beep-page message, and T representes the DRX cycle at the terminal of second sub-district or first sub-district; N:min (T, nB), nB can be pre-configured by first base station or second base station; For example: nB=4T, 2T, T; T/2, T/4, T/8; T/16, T/32, UE_ID be the terminal of first sub-district or interfered cell identify label number (for example: sign international mobile subscriber identity (International Mobile Subscriber Identification Number; IMSI) with 1024 mould).Accordingly, the PF of paging receiving message is also calculated at the terminal of the terminal of second sub-district and first sub-district according to SFN mod T=(T div N) * (UE_ID mod N).Therefore, first base station can make terminal paging receiving message on different PF of the terminal and second sub-district of first sub-district through SFN mod T=(T div N) * (UE_ID mod N) is carried out conversion; Perhaps; Conversion also can be carried out to SFN mod T=(T div N) * (UE_ID mod N) in second base station; But need to guarantee that the PF that finally confirms in first base station and second base station is different; The PF of terminal paging receiving message of terminal and second sub-district of first sub-district is staggered, thereby avoid the beep-page message conflict in the radio frames rank.The PF of terminal paging receiving message of terminal and second sub-district of first sub-district is staggered, thereby avoid the beep-page message conflict in the radio frames rank.

At present; First base station and the second base station specific paging subframe PO place in PF sends beep-page message; Therefore, except the PF of the terminal paging receiving message of the above-mentioned terminal that makes first sub-district and second sub-district staggers, the PO of terminal paging receiving message of terminal and second sub-district of first sub-district is staggered; Specifically can change first base station and send the PO position of beep-page message originally; Perhaps, can also change the PO position that first base station and second base station are sent beep-page message originally simultaneously, but need guarantee that in this case the PO position that first base station and second base station change staggers; Thereby make terminal paging receiving message on different PO of the terminal and second sub-district of first sub-district, realize that the terminal of first sub-district and the terminal of second sub-district avoid the beep-page message conflict in the subframe rank.

First base station and second base station can consult to send separately the PF and/or the PO of beep-page message in advance.Message can be sent to the terminal in advance in first base station or second base station, informs terminal paging receiving message on appointment PF and/or PO, perhaps, is stored the PF and/or the PO of paging receiving message in advance by the terminal.

The paging method that the embodiment of the invention provides; The Radio Resource at the beep-page message place that send in by the interfered cell scope base station; Confirm, perhaps be the Radio Resource of expansion through coordination between website through this base station; Do not take the Radio Resource of the terminal receiving paging signal of interfered cell when making, guarantee the normal paging service at interfered cell terminal, avoid by the Radio Resource conflict of the terminal receiving paging signal of the terminal of interfered cell and interfered cell by the terminal receiving paging signal of interfered cell.

Another embodiment of the paging method that the present invention also provides, in the present embodiment, first beep-page message that send in first cell range first base station sends second beep-page message with second base station in second cell range, be positioned on the different PO.Wherein, second base station is the interference base station of first base station, and first sub-district is by interfered cell, and second sub-district is an interfered cell.The paging method that present embodiment provides from the paging service of paging subframe PO rank assurance interfered cell, avoids interference the beep-page message of sub-district and conflict occurred by the beep-page message of interfered cell.

At present, first base station and second base station confirm to send the PO of first beep-page message and second beep-page message usually according to second mapping table.Second mapping table is used to identify the corresponding relation of Ns, i_s and PO, and corresponding, the PO of paging receiving message is also confirmed at the terminal of the terminal of first sub-district and second sub-district according to second mapping table.FDD (Frequency Division Duplexing; FDD) set of the PO in second mapping table in the system is 0,4,5 and 9 combination, and is as shown in the table:

Time division duplex (Time Division Duplexing; TDD) PO in second mapping table set is 0,1,5 and 6 combination in the system, and is as shown in the table:

Be used to indicate the i_s index of PO position to be: i_s=floor (UE_ID/N) mod Ns

Wherein, Ns=max (1, nB/T), nB=4T, 2T, T, T/2, T/4, T/8, T/16, T/32,

N:min (T, nB), T is discontinuous reception (the Discontinuous Reception at terminal; DRX) cycle, UE_ID be the terminal identify label number (for example: sign international mobile subscriber identity (International Mobile Subscriber Identification Number; IMSI) with 1024 mould).Wherein, the base station can send to the terminal with nB and T through broadcast.

Can find out that from above table in the TDD system, beep-page message is sent to the terminal usually in the base station on the 0th, 1,5 or No. 6 PO, and is corresponding, the terminal is paging receiving message on the 0th, 1,5 or No. 6 PO; In the FDD system, beep-page message is sent to the terminal usually in the base station on the 0th, 4,5 or No. 9 PO, and is corresponding, and the terminal is paging receiving message on the 0th, 4,5 or No. 9 PO.In the paging method that present embodiment provides; On different PO, send beep-page message with second base station through first base station; The terminal of the terminal of first sub-district and second sub-district is paging receiving information on different PO correspondingly, thereby avoid the terminal of first sub-district and the terminal of second sub-district paging conflict to occur.

No matter be TDD or FDD system, two above-mentioned forms can be represented with the form that comprises Parameter1～Parameter7 as follows:

First base station can change PO parameter in the form (Parameter1～Parameter7), thus make the terminal of first sub-district change the PO position of existing paging receiving message.Because different Ns and i_s value can be got with second base station in first base station; For the FDD system; As long as the PO set during the PO among the Parameter1～Parameter7 that guarantees to use first base station gathers in 0,4,5 and 9 subframes of using with second base station is different; Or even do not occur simultaneously, can guarantee that the beep-page message that send first base station and second base station staggers in the PO rank.For the TDD system; As long as the PO in 0,1,5 and 6 subframes of the PO set among the Parameter1～Parameter7 that guarantees to use first base station and the current use in second base station gathers different; Or even do not occur simultaneously, can guarantee that the beep-page message that send first base station and second base station staggers in the PO rank.

That is, if the 2nd PO is a PO in first set of being made up of the 0th, 4,5 and No. 9 PO in the FDD system, then a PO is all the other PO in the outer PO of first set or first set; If the 2nd PO is a PO in second set of being made up of the 0th, 1,5 or No. 6 PO in the TDD system, then a PO is all the other PO in the outer PO of second set or second set.

For example: at present; For the TDD system, when Ns=1, the PO that sends beep-page message is No. 0 paging subframe; Paging conflict appears for fear of the terminal of first sub-district and the terminal of second sub-district; New value can be selected with the PO position Parameter1 of Ns=1 in first base station, and for example: the PO that sends beep-page message becomes the paging subframe No. 3, and is corresponding; The terminal of first sub-district is paging receiving message on No. 3 PO, thereby avoid the terminal of first sub-district and the terminal of second sub-district paging conflict to occur.Need to prove; The value of Ns is 1,2 and 4 in employed second mapping table at present; The value of i_s is 0 to 3; And can increase the value of Ns and/or i_s in the form that comprises Parameter1～Parameter7 that relates in the embodiment of the invention newly; Only need to guarantee that the PO parameter sets in second mapping table of the corresponding newly-increased PO parameter of newly-increased Ns and/or i_s and current use is different, or even do not occur simultaneously, can guarantee that the beep-page message of first base station and second base station transmission staggers in the PO rank.In addition; Change simultaneously in first base station and second base station under the situation of PO of existing transmission beep-page message; Promptly all does not use under the situation of second mapping table first base station and second base station, and same new mapping table can be used in first base station and second base station, for example: first mapping table that all uses Ns, i_s and PO; PO set in this first mapping table is different with the PO set in second mapping table, even does not occur simultaneously.Can also be that first base station is used different mapping tables respectively with second base station; For example: first mapping table is used in first base station; And the 3rd mapping table is used in second base station; Wherein, there is at least one different PO in the 3rd mapping table and first mapping table and/or second mapping table.

For the FDD system; Because second beep-page message can be sent in second base station in second cell range on the 0th, 4,5 or No. 9 PO; Therefore; First beep-page message can be sent in first base station in first cell range on all the other PO outside the 0th, 4, the 5 and No. 9 PO set, corresponding, receives first beep-page message that send first base station on all the other PO outside the 0th, 4,5 and No. 9 PO set of the terminal of first sub-district; For the TDD system; Because second beep-page message can be sent in second base station in second cell range on the 0th, 1,5 or No. 6 PO; Therefore; First beep-page message can be sent to first sub-district in first base station on all the other PO outside 0,1,5 and 6 set, corresponding, receives first beep-page message that send first base station on all the other PO outside the 0th, 1,5 and No. 6 PO set of the terminal of first sub-district.

As another kind of possible implementation; For the FDD system; If second beep-page message is sent in second base station in second cell range on the 0th, 4,5 or No. 9 PO; Then first beep-page message can be on all the other PO in the 0th, 4,5 and No. 9 set be sent in first cell range in first base station, corresponding, reception first beep-page message on all the other PO in the 0th, 4,5 and No. 9 PO set of the terminal of first sub-district; For the TDD system; If second beep-page message is sent in second base station in second cell range on the 0th, 1,5 or No. 6 PO; Then first base station can be on all the other PO in the 0th, 1,5 and No. 6 PO set in first cell range on transmission first beep-page message; Corresponding, receive first beep-page message on all the other PO in the 0th, 1,5 and No. 6 PO set of the terminal of first sub-district.

Present embodiment also provides a kind of possible implementation; First base station adopts first mapping table to confirm to send the PO position of first beep-page message; Second base station also can change the PO position of sending second beep-page message; For example: adopt first mapping table identical to confirm the PO value with first base station; Or, adopt three mapping table different to confirm the PO value, promptly for the FDD system with first mapping table; Second beep-page message also can be sent in second base station in second cell range on the PO outside the set that the 0th, 4,5 and No. 9 PO forms; Correspondence TDD system, second beep-page message also can be sent in second base station in second cell range on the PO outside the set that the 0th, 1,5 and No. 6 PO forms, and promptly first base station and second base station can change the PO position of sending beep-page message simultaneously; Need first base station to guarantee that with the second base station selected different PO parameter beep-page message staggers in the PO rank in this case, first base station and second base station can be in the values that guarantees further to confirm under the prerequisite that PO staggers Ns and i_s.

Wherein, The terminal of first sub-district can be stored the PO set in first mapping table in advance, or Ns and corresponding PO set, or Ns, i_s and corresponding PO set; And then the terminal of first sub-district can confirm to receive the PO of first beep-page message through first mapping table of storage in advance.Can also be; First base station with each parameter in first mapping table (for example: the PO set in first mapping table; Or Ns and corresponding PO set; Or i_s and corresponding PO set, or Ns, i_s and corresponding PO set) send to the terminal of first sub-district, the parameter in these first mapping tables can be carried at radio resource control (Radio Resource Control; RRC) signaling or medium access control system, control element (Medium Access Control Control Element; MACCE) in message or the broadcast etc.The PO of second beep-page message is also confirmed to send in second base station according to first mapping table; First mapping table also can be stored in advance in the terminal of second sub-district; Or send the relevant parameter in first mapping table to the terminal of second sub-district by second base station, repeat no more.

As another kind of possible implementation; First base station can be in advance sends to the terminal of first sub-district with the PO information that is used to receive first beep-page message; Or had under the situation of first mapping table in first sub-district; Ns and i_s value or Ns and corresponding PO set or the PO of i_s and correspondence that will be used for confirm receiving at first mapping table PO of first beep-page message gather the terminal that sends to first sub-district; So that the terminal of first sub-district receives first beep-page message at the PO place of correspondence, wherein, PO information can be carried in RRC signaling or MACCE or the broadcast.

Another embodiment of the paging method that the present invention also provides, in the present embodiment, first beep-page message that send in first cell range first base station sends second beep-page message with second base station in second cell range, be positioned on the different PF.Wherein, second base station is the interference base station of first base station, and first sub-district is by interfered cell, and second sub-district is an interfered cell.The paging method that present embodiment provides from the paging service of radio frames PF rank assurance interfered cell, avoids interference the beep-page message of sub-district and conflict occurred by the beep-page message of interfered cell.

The PF that sends beep-page message is calculated according to SFN mod T=(T div N) * (UE_ID mod N) usually in present first base station and second base station, and wherein, Mod () representes modulo operation, and div representes division arithmetic.SFN is a System Frame Number, if SFN mod T=(T div N) * (UE_ID mod N) sets up, then SFN is for sending the PF of beep-page message, and T is the DRX cycle at the terminal of first sub-district or second sub-district; N:min (T, nB), nB can be pre-configured by first base station or second base station, for example: nB=4T; 2T, T, T/2, T/4; T/8, T/16, T/32, UE_ID are the identify labels number (for example: IMSI and 1024 mould) at the terminal of first sub-district or second sub-district.Accordingly, the PF of paging receiving message is also calculated at the terminal of the terminal of first sub-district and second sub-district according to SFN mod T=(T div N) * (UE_ID mod N).

First base station can be through carrying out conversion to SFN mod T=(T div N) * (UE_ID mod N), and the terminal that makes first sub-district is paging receiving message on the PF of 4 integral multiple at non-SFN.Promptly first base station can be through carrying out conversion to SFN mod T=(T div N) * (UE_ID mod N); Make terminal paging receiving message on different PF of the terminal and second sub-district of first sub-district; The PF of terminal paging receiving message of terminal and second sub-district of first sub-district is staggered, thereby avoid the beep-page message conflict in the radio frames rank.

As a kind of possible implementation, first base station can confirm to send the PF of beep-page message according to following new computational methods, and corresponding, the terminal of first sub-district can be confirmed the PF of paging receiving message according to following new computational methods, and these computational methods are:

(SFN+M)mod?T＝(T/N)×(UE_ID?mod?N)；

Wherein, parameter M=1... [T/nB-1], nB can be pre-configured by first base station, and nB＜T can value nB=T/N, and N is the natural number greater than 1, perhaps is the natural number of 2 multiple, for example: nB=T/2, T/4, T/8, T/16, T/32 etc.

Can find out that from SFN mod T=(T div N) * (UE_ID mod N) for example: when nB=T/4, PF is 4 integral multiple position at SFN; For example: T=1280ms; PF can be the integral multiple position existence of 4,8,12 grades 4 at SFN; The terminal of the terminal of first sub-district and second sub-district is a paging receiving message on the PF of 4 integral multiple at SFN all, thereby can produce paging conflict.If first base station is according to the definite PF that sends beep-page message of (SFN+M) mod T=(T/N) * (UE_ID mod N), for example: work as M=1, nB=T/4; T=1280ms (identical nB and T are adopted with second base station in first base station); Then PF can be 3,7, and the integral multiple position of 11 grades 4 subtracts 1 place and exists.So just, can realize terminal paging receiving message on different PF of the terminal and second sub-district of first sub-district, realize avoiding the beep-page message conflict from the radio frames rank.

Need to prove; (SFN+M) mod T=(T/N) * (UE_ID mod N) only provides the computational methods of a kind of feasible definite PF; But be not the unique method of confirming PF; It is understandable that first base station can also be transformed into various other forms with SFN mod T=(T div N) * (UE_ID mod N), avoid the beep-page message conflict from the radio frames rank with the terminal of realizing first sub-district and the terminal of second sub-district.

Wherein, the M value that the terminal of first sub-district can be stored in advance (or store in advance other SFN mod T=(T div N) * (UE_ID mod N) variation), and then the PF of paging receiving message can be confirmed in the terminal of first sub-district.Can also be; First base station can send to M value (or store in advance other SFN mod T=(T div N) * (UE_ID mod N) variation) terminal of first sub-district, and M value (or store in advance other SFN mod T=(T div N) * (UE_ID mod N) variation) can be carried in RRC signaling or MACCE message or the broadcast etc.

In addition; Second base station also can adopt (SFN+M) mod T=(T/N) * (UE_ID mod N) to confirm to send the PF of second beep-page message; First base station and second base station adopt (SFN+M) mod T=(T/N) * (UE_ID mod N) to confirm to send the PF of beep-page message simultaneously; And in this case, need first base station and second base station to adopt different M values to stagger in the PF rank to guarantee the beep-page message that sends.

Two embodiment in front have described first base station respectively and on the PO different with second beep-page message, have sent first beep-page message to the terminal of first sub-district, and the execution mode of first beep-page message can also be on the PF different with second beep-page message be sent in first base station to the terminal of first sub-district.On this basis, first base station can also change PF and PO simultaneously, and promptly first base station is at different PF with second beep-page message, and different PO goes up and sends first beep-page message to the terminal of first sub-district.Promptly avoid the terminal of first sub-district and the terminal of second sub-district paging conflict to occur from radio frames rank and paging subframe rank simultaneously.

Further, the PF and/or the PO of beep-page message can mode be through consultation confirmed to send separately in first base station and second base station before sending first beep-page message and second beep-page message.Fig. 3 is the flow chart of first base station provided by the invention and the second base station negotiate PF and/or PO embodiment, comprising:
