Background technology
WiMAX (Worldwide Interoperability for Microwave Access, micro-wave access global inter communication), be called 802.16 wireless MANs again, it is a kind of broadband wireless connectivity scenario that last mile is provided for enterprise and domestic consumer, can realize high coverage in data communication field, for example can cover 25~30 miles scope, this technology is based on the serial wideband wireless standard of IEEE 802.16.Wherein, 802.16e belongs to mobile broadband wireless and inserts aerial standard.
Defined two kinds of types that insert MBS (Multicast Broadcast Service, Multimedia Broadcast Multicast Service) in IEEE 802.16e: single BS (Base Station, base station) access and many BS insert.Wherein, many BS accesses are that a plurality of BS send identical MBS data simultaneously on identical running time-frequency resource, therefore need between a plurality of BS synchronous.In the type that many BS insert, with identical CID (Connection Identifier, connection identifier) with identical SA (Security Association, Security Association) BS of the identical MBS data of transmission forms the set of a BS, this set is called MBS Zone (MBS zone), each MBSZone can identify with a MBS Zone ID (MBS Zone Identifier, MBS Zone sign).Wherein, CID is the sign of the unidirectional mapping between MAC (Media Access Control, medium access control) the layer peer-entities of BS and MS, CID can represent professional the connection, can represent that also management connects, if management connects, then be that uplink and downlink are shared; If professional the connection then is that uplink and downlink separate.Can comprise a plurality of Logic Channel Identifiers (Logical channelID) below the MBS CID, the content that each Logic Channel Identifier (Logical channel ID) is corresponding different.
The MS that has proposed Idle mode (idle pulley) under many BS access style in IEEE802.16e receives the method for MBS, and application system as shown in Figure 1.Concrete method is as follows: obtain MBS Zone ID when MS communicates by letter with BS.Enter Idle mode if obtain the MS of MBS Zone ID, this MS can continue to receive from the BS that broadcasts identical MBS Zone the data of identical MBS, and MS uses the CID of acquisition when registering and the data that SA can continue to receive this MBS.If move to another one MBS Zone at the MS of Idle mode, then MS need obtain new CID and SA in the registration of the BS place in the new MBS Zone, continues to receive the MBS data.
The MS that detects Idle Mode when upper layer entity has message to come then, can initiate the process of paging MS: PC (Paging Controller, paging controller) at whole PG (Paging Group, paging group) notice PA (Paging Agent in, paging agent) need to initiate beep-page message, and with on need the MS sign of paging; Then PA generates the beep-page message that has certain MS sign and sends on eating dishes without rice or wine, and just knows that when MS receives the MS sign of oneself mating in beep-page message PA is at this MS of paging; Next MS carries out networking process.Wherein, BS is PA in IEEE 802.16e, paging group is that one or more PA is placed on group the inside, and MS need register own position when having striden paging group when MS moves to, so just can be inside a paging group when PC needs paging MS this MS of paging.As shown in table 1, give to have the beep-page message MOB_PAG-ADV that BS issues among the IEEE 802.16e.This message is broadcast to MS by BS, and the cryptographic Hash that is resolved to the MS MAC Address in the message as MS is thought BS in paging oneself during with own Hash values match, and MS is according to Action Code (action code) execution corresponding action then.

Step s201, the base station is provided with beep-page message, carries paging multi-user installation indication information in the described message; And send described beep-page message to subscriber equipment.Wherein, when beep-page message is MBS MAP, described paging multi-user installation indication information Paging Indication Information comprises the multicast connection identifiers (Multicast CID) of paging, more excellent, can further include in the number of multicast connection identifiers (Multicast CID) of paging and paging reason (Paging Cause perhaps is action indication code ActionCode), access probability (Ranging Probability), the Logic Channel Identifier (Logical channel ID) one or multinomial.When beep-page message was MOB_PAG_ADV, described paging multi-user installation indication information comprised MBS area identification MBS Zone ID and multicast connection identifiers (Multicast CID).Wherein, subscriber equipment comprises mobile station MS, but can also comprise other equipment, as SS etc.
Step s202, subscriber equipment receives the beep-page message that carries paging multi-user installation indication information.
Step s203, subscriber equipment exits from idle mode according to described paging multi-user installation indication information.Described beep-page message is a MBS MAP message, subscriber equipment judges whether comprise described paging multi-user installation indication information in the described MBS MAP message, if comprise then further judge whether comprise the professional corresponding multicast connection identifiers (MulticastCID) of the MBS that adds itself in the paging multi-user installation indication information, if comprise then exit from idle mode.
When described beep-page message is MOB_PAG_ADV message, described paging multi-user installation indication information comprises MBS Zone ID and multicast connection identifiers (Multicast CID), described subscriber equipment judges whether comprise the professional corresponding multicast connection identifiers (Multicast CID) of the MBS that adds itself in the described MOB_PAG_ADV message, if comprise then exit from idle mode.In addition, when also carrying the paging reason in the paging multi-user installation indication information, described subscriber equipment is initiated operation flow according to described paging reason after exitting from idle mode according to described paging multi-user installation indication information.
The embodiment of the invention two, as shown in Figure 3, may further comprise the steps for MBS MAP is that example is described in detail with the beep-page message:
Step s301, in MBS MAP message, increase and carry Paging Indication Information (paging multi-user installation indication information), one or more MBS business is carried out paging, and paging multi-user installation indication information can be a TLV, a flag bit or a field.After in MBS MAP, increasing paging indication information, because the MS of a certain MBS business of a plurality of addings can go to receive the professional corresponding MBS MAP message of this MBS, therefore BS can come the MS that is in idle pulley of this MBS business of a plurality of uses of paging by the paging multi-user installation indication information in the MBS MAP message, notifies these MS to withdraw from IdleMode.
Step s302, the MS that has added a certain MBS business receives corresponding M BS MAP, if MBSMAP indicates the MBS business of adding the paging indication is arranged, and whether comprise the professional corresponding multicast connection identifiers (Multicast CID) of the MBS that adds itself in the paging multi-user installation indication information, then exit from idle mode; If the paging multi-user installation indication information in the beep-page message also comprises paging reason (perhaps being called action indication code Action Code), make a MBS Counting (MBS business statistics) such as this MBS business because of needs and carry out paging, carry a paging cause field so, the reason of its value representation paging is the MBS business statistics, so a plurality of MS of idle pulley that are in are after coming by the paging indication is awake, because it is the MBS business statistics that MS knows the reason of waking up, so MS will initiate the relevant flow process of MBSCounting (MBS business statistics) after waking up and coming, such as professional registering flow path.
The method that increases paging multi-user installation indication information in MBS MAP is a lot, and for example the MBSMAP message format is as shown in table 2, but is not limited thereto.

In the embodiments of the invention two, the MS of this MBS business of a plurality of uses can wake up in the moment that MBS_MAP arrives and receive MBS data (comprising MBS_MAP message), therefore by in MBS MAP, carrying the MS that paging indication information once just can this MBS business of a plurality of uses of paging, can save the expense that repeatedly sends MOB_PAG_ADV message compared with the way of existing standard.When BS does not have this MBS business, need not send any relevant paging signaling, saving is eated dishes without rice or wine.
In addition in the embodiments of the invention two, at there not being SFN (Single FrequencyNetwork, single frequency network) gain to improve in the prior art.Because SFN is the radio-transmitting station that is in synchronous regime by a plurality of different locations, at one time, with the same signal of same frequency emission, realizing the reliable covering to certain service area, the data of transmitting by the SFN mode can obtain a plurality of transmitting stations and launch the energy stack gain that brings simultaneously.And in the prior art since subscriber equipment can not be at one time, with the same signal of same frequency emission, therefore there is not the SFN gain, and the embodiment of the invention can use the SFN mode to send because of MBS MAP message, and the paging multi-user installation indication information that therefore is placed among the MBS MAP has the SFN gain.
The length that is noted that each specified in present embodiment field is a kind of mode that can realize, length differs and is decided to be the value in listed in the table, for other value also is fine, if the meaning of field the same with field among the embodiment all be the present embodiment scope.
The embodiment of the invention three is that MOB_PAG_ADV is that example is described in detail with the beep-page message, as shown in Figure 4, may further comprise the steps:
Step s401, BS by MOB_PAG_ADV message carry MBS Zone ID, multicast connection identifiers (Multicast CID) is carried out paging.Situation at the MS of the same MBS business of a plurality of uses of paging, employing is based on the paging granularity of Multicast CID, but not MS ID granularity, specific implementation is revised original MOB_PAG_ADV message exactly, in this message, increase MBS area identification field (MBS Zone ID) and multicast connection identifiers (Multicast CID), as shown in table 5.
Step s402, the MS/SS of a plurality of MOB_PAG_ADV of receiving message judge whether the professional corresponding MBS CID of the MBS that oneself adds is included in the middle of the MOB_PAG_ADV, if will exit from idle mode.
