Embodiment
Basic thought of the present invention is: for MZONE and the LZONE of ABS distributes different PG ID, and be that YBS distributes PG ID, each base station sends to the terminal in self coverage by the PG ID that distributes to self.So, can guarantee the backward compatibility to traditional base station under idle pulley.
Wherein, described base station is ABS or YBS; Described can base station mode by broadcast or multicast or clean culture send PG ID to terminal.Because ABS comprises LZONE and MZONE, and the LZONE of ABS and the MZONE of ABS be assigned different PG ID separately, and the LZONE of ABS and the MZONE of ABS can send the PG ID that is assigned to separately separately to the terminal in self coverage.
In the present invention, all base stations in network or base station subregion can be divided into respectively to the paging group of supporting 802.16m agreement or the paging group of supporting 802.16e agreement, and distribute different PG ID for each paging group, here, described base station subregion refers to the LZONE of ABS or the MZONE of ABS, and described base station refers to YBS.Each supports the paging group of 802.16m to comprise the MZONE of at least one ABS, and each supports the paging group of 802.16e to comprise LZONE and/or the YBS of at least one ABS.In other words, the MZONE of ABS can only be divided in the paging group of supporting 802.16m, and the LZONE of ABS and/or YBS can only be divided in the paging group of supporting 802.16e.
In the system of ABS and YBS mixed networking, the MZONE of the LZONE of ABS, ABS and YBS are divided into respectively in different paging groups, wherein, the LZONE of ABS will put together and unify to carry out the division of paging group with YBS.Generally, together with the LZONE of the LZONE of certain ABS and the YBS being adjacent or the ABS that is adjacent, form a paging group, use identical PG ID; Together with the MZONE of the MZONE of certain ABS and the ABS being adjacent, form a paging group, use identical PG ID.Can find out, for same ABS, the LZONE of ABS and the MZONE of ABS have different PG ID.Certainly, the LZONE of different ABS and the MZONE of ABS and YBS are also assigned different PG ID.
Further, based on PG ID, the present invention also comprises and when call terminal or terminal work mode change, carries out position renewal or base station is notified and recommend terminal to use the operations such as 802.16m protocol mode.
Give an example, as shown in Figure 1a, in ABS and YBS mixed networking system, comprise ABS1～ABS6, YBS1～YBS2, wherein, each ABS includes the LZONE of ABS and the MZONE of ABS, such as: ABS1 comprises the LZONE of ABS1 and the MZONE of ABS1, ABS2 comprises the LZONE of ABS2 and the MZONE of ABS2 ... the rest may be inferred.While dividing paging group, the MZONE of all ABS is put together and unifies to carry out paging group division; The LZONE of YBS and all ABS is put together and unifies to carry out paging group division.
As shown in Figure 1 b, the mixed networking system shown in Fig. 1 a is divided into four paging group PG1～PG4, and wherein, PG1, for supporting the paging group of 802.16e agreement, comprises LZONE and YBS1, the YBS2 of ABS1 and ABS4; PG2 also, for supporting the paging group of 802.16e agreement, comprises the LZONE of ABS2, ABS3, ABS5 and ABS6; PG3 and PG4 are the paging group of supporting 802.16m agreement, and PG3 comprises the MZONE of ABS1, ABS2 and ABS4; PG4 comprises the MZONE of ABS3, ABS5 and ABS6.
In mixed networking system, when dividing paging group and distributing PG ID for each paging group, there are two kinds of implementations:
The first implementation, first distinguishes the PG ID that supports 802.16e agreement and support 802.16m agreement, then divides paging group, afterwards for supporting the paging group of different agreement to distribute corresponding PG ID.Concrete: first distinguish the PG ID that supports 802.16m agreement and 802.16e agreement, for example: the PG ID that is 1 by high four bit positions is for expressing support for the PG ID of 802.16e agreement, and the PG ID that is 0 by high four bit positions is for expressing support for the PG ID of 802.16m; Or, using the PG ID of odd number as the PG ID that supports 802.16e agreement, the PG ID of even number is as supporting PG ID of 802.16m etc., as long as can mark off two class PGID, one class is as the PG ID that supports 802.16e, and a class is as the PG ID that supports 802.16m.Afterwards, by the LZONE of ABS and the YBS unified division of carrying out paging group of putting together, its PG ID adopts the PG ID that supports 802.16e agreement; The MZONE of ABS is put together and unifies to carry out the division of paging group, and its PG ID adopts the PG ID that supports 802.16m agreement.
The second implementation, first divides paging group, then distributes different PG ID for each paging group.Concrete: the unified division of carrying out paging group of first LZONE of ABS and YBS being put together, then distribute the PG ID of support 802.16e agreement for it; And, the MZONE of ABS is put together and unifies to carry out the division of paging group, then be that it distributes and the PG ID that supports that 802.16e agreement is different.Or, after dividing paging group, first distributing the PG ID of the paging group of supporting 802.16m agreement, the PG ID of the paging group of 802.16e agreement is supported in reallocation, as long as guarantee that PG ID is different, can each paging group of unique identification.
Division based on above-mentioned paging group, when terminal work mode changes, terminal can be carried out position renewal; And after position is updated successfully, enter the unavailable interval of idle pulley paging under new mode of operation.Specific implementation flow process as shown in Figure 2, comprises the following steps:
Step 201: when terminal determines that the mode of operation of self changes, first synchronize with current affiliated base station, obtain afterwards system parameters;
Here, described mode of operation refers to that terminal works is under 802.16e protocol mode, or is operated under 802.16m protocol mode; Described current affiliated base station may be ABS, may be also YBS.
The reason that described mode of operation changes can be: the AMS being operated under 802.16e protocol mode moves to ABS from YBS, and AMS has reselected the MZONE of ABS; Be operated in AMS under 802.16e protocol mode in ABS, change for a certain reason mode of operation under 802.16m protocol mode; The AMS being operated under 802.16m protocol mode moves to YBS from ABS.In this step, when terminal work mode changes, terminal does not exit from idle mode.
As for terminal how with current under base station synchronization, how to obtain system parameters and be prior art, be not described in detail in this.
Step 202: terminal is obtained after system parameters, determines and carries out position renewal according to the difference of PG ID, and obtain the paging parameters under new mode of operation.
Here, the system parameters of obtaining comprises base station or affiliated PG ID corresponding to paging group of base station subregion that terminal reselects; Described paging parameters comprises the parameters such as paging sign after renewal, paging cycle, side-play amount.
Describedly according to the difference of PG ID, determine and to carry out position renewal specifically: terminal gets after the PG ID in system parameters, compare with the PG ID before self storage, find that PG ID is inconsistent, determine to carry out position renewal.
Wherein, how obtaining paging parameters is prior art, repeats no more herein.
Step 203: after terminal position is updated successfully, enters the unavailable interval of paging of the idle pulley under new mode of operation, and use new paging parameters to carry out work.
According to the change difference of reason of mode of operation, the realization flow that in three kinds of situations, terminal work mode changes is described respectively below.
Situation one: the AMS in idle pulley moves to ABS from YBS.
AMS in idle pulley is operated under 802.16e protocol mode, and this AMS moves to ABS from YBS, and after overscanning, the base station subregion of this AMS first-selection may be the LZONE of ABS, may be also the MZONE of ABS.Here, terminal, when reselecting base station, can be carried out according to concrete selection mode or the strategy arranging of manufacturer terminal, such as: determine and select good base station or the base station subregion of current demand signal, by scanning, know that the signal of the MZONE of ABS is better than the signal of the LZONE of ABS, selects the MZONE of ABS.Suppose that primary base station subregion is the MZONE of ABS, the mode of operation of terminal changes.
Terminal after mode of operation changes, first with current under base station synchronization, then receiving system message.Because the PG ID of LZONE and MZONE is different, terminal position upgrades, and obtains paging parameters.If position is updated successfully, terminal enters the unavailable interval of paging of the idle pulley under 802.16m protocol mode.
Situation two: the AMS in idle pulley for a certain reason, need to change to 802.16m protocol mode from 802.16e protocol mode.
AMS in idle pulley is operated under 802.16e protocol mode, and under ABS base station, for a certain reason, mode of operation will change to 802.16m protocol mode from 802.16e protocol mode, terminal is after mode of operation changes, with current affiliated base station synchronization, then receiving system message.Receive after system message, because the PG ID of LZONE and MZONE is different, terminal position upgrades, and obtains paging parameters.If position is updated successfully, terminal enters the unavailable interval of paging of the idle pulley under 802.16m protocol mode.
Situation three: the AMS in idle pulley moves to YBS from ABS.
AMS in idle pulley is operated under 802.16m protocol mode, from ABS, moves to YBS, and now terminal can only scan YBS, and mode of operation must change, and terminal changes to 802.16e protocol mode from 802.16m protocol mode.After terminal changes, scans in mode of operation, with current affiliated base station synchronization, afterwards receiving system message.Receive after system message, because the PG ID of MZONE and LZONE is different, terminal position upgrades, and obtains paging parameters, if position is updated successfully, terminal enters the unavailable interval of paging of the idle pulley under 802.16e protocol mode.
In actual applications, because ABS comprises LZONE and MZONE two parts, the terminal self that can exist ABS notice to be operated under 802.16e protocol mode is supported 802.16m protocol mode, or further recommend the situation of terminal works under 802.16m protocol mode, specific implementation flow process as shown in Figure 3, comprising:
Step 301: base station knows that current terminal is AMS, and is operated under 802.16e protocol mode;
Step 302: base station notifies current terminal self to support 802.16m protocol mode as required;
Conventionally, the LZONE of ABS can support 802.16m agreement by indicating terminal self in broadcast; If terminal position upgrades, the LZONE of ABS also can, in the ranging response message RNG_RSP replying to the terminal of carrying out position renewal, indicate and self support 802.16m agreement; In this RNG_RSP message, also can further carry the protocol-dependent information parameter of 802.16m.
Step 303: further, base station recommends terminal works as required under 802.16m protocol mode;
Step 304: terminal is received and recommended the rear mode of operation that determines self of indication; Here, terminal can reselect according to the selection strategy of self, such as: select the good mode of operation of signal of communication, because the signal of communication providing under 802.16e protocol mode is provided the signal of communication providing under 802.16m protocol mode, again select and be operated under 802.16m protocol mode.
Concrete, can realize in the following ways base station to the notice of mode of operation and recommendation:
Embodiment 1:
When the AMS in idle pulley is operated under 802.16e protocol mode, from YBS, move to ABS, after overscanning, its first-selected base station subregion is the LZONE of ABS, if the LZONE of ABS and YBS belong to different PG ID, under 802.16e protocol mode, AMS occurrence positions upgrades, when occurrence positions upgrades, ABS receives the distance measurement request message RNG_REQ of AMS, can know the protocol version mac version that this terminal is supported, and then can know this terminal support 802.16m agreement, now, ABS can notify and can further recommend AMS to be operated in 802.16m protocol mode, this indication will be placed in RNG_RSP message, terminal is received after this indication, by according to the situation of self, determine the mode of operation of oneself, determine whether to reselect mode of operation.
Embodiment 2:
When the AMS in idle pulley is operated under 802.16e protocol mode, and under ABS base station, now base station, according to the information of having obtained before, knows that current terminal is AMS terminal, and knows current terminal support 802.16m agreement mode of operation.So, if base station thinks that current terminal can be operated under 802.16m protocol mode, beep-page message can be sent out to terminal in base station, allows this terminal position upgrade, while upgrading in position, ABS can notify and further recommend AMS to be operated in 802.16m protocol mode, this indication will be placed in RNG_RSP message, and terminal receives after this indication, by according to the situation of self, determine the mode of operation of oneself, determine whether to reselect mode of operation.
Division based on paging group of the present invention, the paging flow process in the present invention as shown in Figure 4, comprising:
Step 401: determine PG ID according to the information of paged terminal, then judge that paging group that determined PG ID is corresponding is comprised of LZONE and/or the YBS of ABS, or formed by the MZONE of ABS;
Here, according to the composition of paging group, just can further know that terminal is to be positioned under the base station or base station subregion of supporting 802.16e agreement, is still positioned under the base station or base station subregion of supporting 802.16m agreement.Described PG ID portability in the information relevant with paging, as: in beep-page message, comprise PG ID.
