Description
Technical field
The present invention relates to the wireless metropolitan area network technology, particularly the paging method in the wireless MAN.
Background technology
(the Institute of Electrical and Electronics Engineers of Institute of Electrical and Electronics Engineers, be called for short " IEEE ") 802 worked out different standards at the different market demands and application model in wireless domain, as be applied to PAN (Personal Area Network) (Personal Area Network, be called for short " PAN ") the IEEE802.15 standard, be applied to IEEE 802.11 standards of WLAN (wireless local area network) etc.
Wherein, IEEE 802.16 is for working out wireless MAN (Wireless metropolitan areanetworks, abbreviation " WMAN ") working group of standard establishment, this working group mainly is responsible for the air-interface standard of fixed wireless access, relate to Multi-Channel Microwave Distribution System (Microwave MultipointDistribution System, abbreviation " MMDS "), LMDS technology such as (Local MultipointDistribution System/Service are called for short " LMDS ").Since micro-wave access to global intercommunication (Worldwide Interoperability for Microwave Access joins in the establishment of 802.16e task groups and a lot of main flow equipment manufacturers of support mobility, be called for short " WiMAX ") after, IEEE 802.16e has attracted increasing sight.
The idle pulley that defines in IEEE 802.16e standard is a kind of terminal work mode in the mobile wide-band wire-less accessing system.Travelling carriage (Mobile Subscribe Station is called for short " MSS ") can enter idle pulley by sending message request.Similarly, serving BS (Serving Base Station is called for short " Serving BS ") also can initiatively require MSS to enter idle pulley by sending message.No matter be that MSS initiatively initiates to ask to enter idle pulley, or Serving BS initiatively requires MSS to enter idle pulley by sending message, MSS will finish the process of registering, entering idle pulley in official hour.
The MSS that is under the idle pulley can move in a very big zone, and MSS needn't register to the base station (Base Station is called for short " BS ") in the sub-district of roaming when roaming in this zone.Simultaneously, when MSS roams into different districts, the normal running flow process such as needn't switch, save MSS power and interface-free resources.But MSS just needs to receive the downlink broadcast service message every certain cycle, knows by broadcast whether this MSS has downlink business to send, and whether just check has paging group that this MSS is carried out paging.
The group that paging group is made up of a plurality of BS.The purpose of paging group is to constitute a continuous zone, makes that MSS does not need to send uplink service in this zone, still can judge whether to send to its downlink business by descending paging channel.In general, the size in paging group zone there is certain requirement, on the one hand must be enough greatly to guarantee that most of MSS remain in the same paging group scope in a long time; Paging group is enough little again, to guarantee that be rational a paging group to the expense that MSS carries out paging.
At present, the paging reference model under the idle pulley that defines in the WiMAX system as shown in Figure 1.This system comprises access service network gateway (Access Service Network GateWay is called for short " ASNGW "), paging controller (Paging Controller is called for short " PC "), location register network entities such as (LR).Wherein, PC is the network entity of control MSS idle pulley activity, this entity is a logic entity in present WiMAX system, with another logic entity Authenticator (authenticator) (may realize in same physical NE as a part of logic function of Authenticator) in close relations.Its physical location may be arranged in the physical NE ASN GW of WiMAX system, also may be arranged in another independently physical NE.LR is used to preserve state information, paging information and the service flow relevant information of MSS.In general, the corresponding LR logic entity of PC logic entity meeting, and two logic entities are realized in same physical NE.
According to paging model shown in Figure 1, when MSS active request on certain BS enters idle pulley, when perhaps certain BS instruct MS S enters idle pulley, by MSS and this BS, and the interacting message between this BS and the rear end network element ASN GW, this MSS of notice PC (realizing in ASN GW1) has entered idle pulley, and preserves state information, paging information and the service stream information of this MSS in the LR of correspondence.MSS can carry information that need to ask reservation when it enters idle pulley in issuing the idle-mode request message of this BS, this BS also can be provided with similar information in the idle mode request response message, be used for notifying the relevant information of MSS, and the ID of PC is notified to this MSS in that LR kept.
After MSS is entering idle pulley, need to discharge corresponding R4, R6 interface, but need to keep the Interface R3 between home agent (HA) and the Foreign Agent (FA).
In addition, under idle pulley, MSS needs periodically to initiate the position updating request idle message to the BS at current place.BS receives the location update message that sends back-end network after this message according to the ID of PC in the message to corresponding PC.PC judges according to this message whether this MSS enters new paging group, if then upgrade the corresponding information among the LR.
In the discussion of WiMAX Canada meeting, by WIMAX forum document " 050708_NWG_Functional_Decomposition_Paging-R4.doc " (Chinese can be translated into " 050708 NWG paging function decomposes edition 4 "), paging reference model and paging flow process have been had further concrete definition, and this paper quotes in full the document at this.In brief, the document is not made concrete restriction and regulation to the division of paging group, so paging group can be crossed over ASN GW; In addition, according to the description of the document, must in LR, carry out pre-configured by the corresponding relation to paging group and ASN GW.
In actual applications, there is following problem in such scheme: during paging group under data distributing is given certain terminal, PC may need beep-page message is handed down to a plurality of ASNGW of paging group under the terminal, has increased the quantity of beep-page message.In addition, in LR, must dispose the corresponding relation of paging group and ASN GW, thereby cause unnecessary configuring maintenance work.
Cause the main cause of this situation to be, as mentioned above, in the relevant prior art any restriction or regulation are not done in the division of paging group, cause paging group may cross over ASN GW.Specifically, as shown in Figure 2, paging group 1 and paging group 3 have all been striden two ASN GW.Therefore, when data distributing was given terminal in paging group 1 or the paging group 3, PC need be handed down to beep-page message a plurality of ASN GW under paging group 1 or the paging group 3, thereby has increased the quantity of beep-page message.In addition, in LR, must dispose the corresponding relation of paging group and ASN GW, this is because if there is not the corresponding relation of paging group and ASN GW among the LR, and when beep-page message need be handed down to certain terminal, PC will not know beep-page message to be handed down to which ASN GW.But well-known, the corresponding relation of configuration paging group and ASN GW also will certainly cause unnecessary configuring maintenance work in LR.
Summary of the invention
In view of this, main purpose of the present invention is to provide the paging method in a kind of wireless MAN, makes maintain configuration work reduce, and paging range and quantity reduce.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
At first need explanation, defined the zone that comprises a plurality of BS, i.e. a paging group in the present invention.In this paging group, the location update message of MSS can send among the PC/LR of this MSS grappling by same ASN GW, but difference is, the present invention sets paging group can not cross over ASN GW, in other words, when an ASN GW had comprised a Paging Group ID, other ASN GW can not comprise identical Paging Group ID.But one of ordinary skill in the art can be understood, and under this setting, same BS still can be in a plurality of paging groups.
Fig. 3 illustrates the position new technological process more in the paging method in the wireless MAN according to an embodiment of the invention.As shown in the figure, at first, in step 301, MSS initiates the position renewal by send " RNG_REQ " message to Serving BS, carries MSS ID (ID of travelling carriage) and PC ID (ID of paging controller) in this message.
Then,, after Serving BS receives the location update message of MSS, initiate position updating request " LU Request " message to PC/LR, carry MSS ID in this message, BSID and PC ID by ServingGW in step 302.
After this, in step 303, Serving GW transmits position updating request " LU Request " message to PC/LR, and increases Serving GW ID cell in the message of transmitting.A part of logic function that PC/LR can be used as logic entity Authenticator (authenticator) realizes in same physical entity.
In step 304, after PC/LR receives position updating request,, note the residing Serving GW of MSS id information according to the ServingGW ID information source of carrying in this message.Because the BS that accepts to upgrade MSS initiation position may belong to a plurality of paging groups, therefore, here be that MSS distributes a suitable paging group ID.PC/LR upgrades response message " LU Response " to Serving GW feedback position then, carries MSS ID, PGID, PCID and BSID in this response message.
Serving GW id information of noting and paging group ID have formed the corresponding relation between Serving GW and the paging group.This correspondence can only be passed through manual configuration in the prior art, and just can realize automatically after having used technical scheme of the present invention.This is because the present invention has increased restrictive condition newly to the paging group scope, paging group only may corresponding ASN GW, and institute becomes possibility so that PC/LR writes down the corresponding relation of Serving GW and paging group automatically when the location update message of receiving from Serving GW.Automatically the corresponding relation that generates paging group and Serving GW can guarantee the correctness of corresponding relation, and efficient improves greatly with respect to manual configuration.In the prior art, because possible corresponding a plurality of ASN GW of paging group, so even PC/LR receives the location update message from a Serving GW, can not guarantee not comprise in the corresponding paging group other ASN GW, so necessary manual configuration causes workload possibility big, that make mistakes also bigger.
After this, in step 305, Serving GW transmits the position to Serving BS and upgrades response message " LU Response ".
In step 306, Serving BS replys " RNG_RSP " message to MSS, shows that the position upgrades successfully, wherein, carries PGID, PCID information in " RNG_RSP " message.
In step 307, Serving BS replys the position to PC/LR and upgrades acknowledge message " LU Confirm ", shows that correlated process completes successfully.
After this, Serving GW transmits the position and upgrades acknowledge message " LU Confirm " to PC/LR, and PC/LR finally finishes the positional information of upgrading MSS after receiving this message.
Fig. 4 illustrates the paging flow process in the paging method in the wireless MAN according to an embodiment of the invention.As shown in the figure, at first, in step 401, when network need directly send to FA (AGW) with downlink data (Downlink Data) by HA when the MSS that is in idle pulley (IDLE attitude) sends data.
After this, in step 402, FA finds that the MSS that will receive data is in the IDLE attitude, just sends the PC/Authenticator of " MSS Info Req " message to the MSS grappling, requires to obtain the MSS relevant information and this MSS is carried out paging.Should comprise MSID and pagingind in " MSS Info Req " message.
Then, in step 403, PC/Authenticator returns " MSS Info Rsp " message and gives FA, carries MSID in the message, and relevant session information.
In step 404, the ServingASN GW id information of record when PC/Authenticator upgrades in the position according to MSS sends beep-page message " Paging Announce " to Serving GW, carries MSS ID and PG ID (paging group sign) in this message.
After this, in step 405, Serving GW searches allocation list according to PG ID, and beep-page message " Paging Announce " is forwarded among the pairing BS of paging group (Paging Group), requires in these BS the specified MSS of MSS ID to be carried out paging.
At last, in step 406, BS is at the broadcast paging messages of eating dishes without rice or wine " Paging Announce ".Because the present invention is limited in the scope of paging group in the ASN GW, the efficient of paging has improved so that paging range and quantity reduce in institute.
Though by with reference to some preferred embodiment of the present invention, the present invention is illustrated and describes, those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
