Embodiment

In the connection mode, MS can carry short message by the whole or part of the TLV using message, sends RNG-REQ to BS (base station).For reception, MS carries short message by using TLV, receives RNG-RSP from BS.Other message and control message can be used according to being used for.

Fig. 1 shows an example of cellular wireless system 10.MS12,14 can be mobile or fixing, and can adopt the form of any one in cell phone, net book, personal computer, media player, apparatus or other wireless connectivity devices multiple.MS can also be called subscriber station, distant station, terminal or other term.

Provide multiple base station (BS) 16-24 within the system, to provide connection for MS.According to application, BS can adopt multiple different form, and can cover larger or less region and transmitting power.Although these BS are illustrated as being similar in FIG, they can also carry out connecting and configuring differently from one another.In some applications, Network Access Point or MS peer-to-peer can serve as or be used as BS.In described example, a MS registers to BS19, and the 2nd MS registers to another BS23.This registration allows each MS and BS to communicate, to support all services that this MS and system are supported.

Each BS16-24 is connected to gateway (GW).There are three gateways 25,26,27.Each gateway supports several BS.These gateways can be interconnected, and also can mutually not connect, and these gateways are all connected to connectivity serving network (CSN) 30 directly or indirectly.One or more CSN can be there is in any one system.CSN is coupled to phone or data network backbone network 31, and this backbone network provides the access to other telephone system, data server and service etc.In some instances, BS by backbone network 31 instead of can be directly connected to CSN by gateway.

In described example, system management and management can be distributed between BS, GW and CSN in a number of different manners.For communication, by BS and GW connected separately, a MS12 can communicate with the 2nd MS.If two MS are all in the registration of same BS place, then this BS can support communication when without the need to being carried out route by GW.Similarly, if the 2nd MS is connected to another system, CSN or ISP (ISP), then these two MS can be communicated by backbone network 31.

Fig. 1 shows an exemplary network, but the present invention can be applied to the configuration of diversified heterogeneous networks, and can to communication carry out differently route to be applicable to different situations and application.

Fig. 2 shows and uses L2 transfer mechanism to send the example of the short message of text message or other type.It is the concept using MAC control plane to transmit more higher layer message that L2 transmits.In WiMAX system, this can be L2 (layer 2) the transmission message of such as L2-XFER and so on.L2 transmission uses specific type and subtype to transmit message payload, and (such as, type 6, subtype are a).MS can in advance with BS agreed bandwidth, to use L2 transfer mechanism to send message payload on uplink.

Subsequently, BS provides SMS to confirm 33.As initial message transmits, L2 can be used to transmit message.L2 transmits the particular type and subtype (such as, type 6, subtype b) that use for this confirmation.

Transmit message to two in Fig. 2 kind to change.First transmission message 32 is not carry the control message being intended to go to base station, but comprises the text message or other short message that are intended to go to another user.Conventional L2-XFER has type and subtype attribute.In order to carry short message, define specific " subtype " of specific " type " of such as type 6 and such as subtype.When there is the short message that will transmit, TLV (type lengths values) field be associated or other field can be inserted in L2-XFER control message with this short message.Data in this field can substitute with for the short message of user and mark (such as, type and sub-type field), are user message instead of control message to indicate this short message.

In fig. 2, BS can also use L2-XFER message to come to send SMS to MS.First, L2-XFER message 34 is sent to MS.As the L2-XFER from MS, no matter have or do not have and control relevant TLV parameter with other, this message can comprise the TLV field be associated with the short message for MS user.Any specific predefined type and subtype can be used to identify the TLV of SMS.Such as, as the transmission from MS, can type of service 6, subtype a.Or in the connection mode, BS can send to MS user the L2-XFER comprising the confirmation with text.

MS uses acknowledge message 35 to reply the SMS from BS.This message can also have the form of AAI_L2-XFER, has specific type and subtype (such as, type 6, subtype b).This confirmation can also comprise another SMS.For the MS under connection mode, system other MAC control message of choice for use (such as, find range (ranging) or registration message) can transmit short message.These message can have " type " specially for SMS or the definition of another kind of user message transportation protocol.

At the idling mode, BS with MS does not carry out being connected the exchange allowing L2 to transmit message.In figure 3, BS has the short message that will send to MS, but under MS is in idle pulley.Therefore, this MS can not receive RNG-RSP as illustrated in fig. 2.BS sends paging 36 to MS.In described example, this figure is the AAI_PAG-ADV with command code 0b01.Use this paging to carry out order MS and carry out location updating.First these stations perform range finding 37 with from BS bandwidth on demand.Subsequently, MS responds, and carrys out starting position renewal by sending conventional RNG-REQ38.In one example, this conventional RNG-REQ can be the AAI_RNG-REQ that CDMA distributes on A-MAPIE (for the RAID1 that finds range and mask designator).

But BS does not use conventional RNG-RSP to reply.On the contrary, MS oppositely receives the RNG-RSP40 comprising the TLV field relevant with this SMS from BS.As previously mentioned, this message can comprise control message, also can not comprise control message.In described example, be there is CDMA distribute the A-MAPIE message 41 of (for the RAID1 that finds range and mask designator) after this RNG-RSP.BS continues to send this message 42, until it receives positive acknowledgement 43 from MS.BS and MS all can count timer, until receive positive acknowledgement.MS has the timer distributing A-MAPIE for CDMA, and BS has the timer for positive acknowledgement.As an alternative, MS can change other control message sending ranging message or also comprise SMS text except positive acknowledgement into.

In the particular example of as shown in Figure 3, when BS has the down link SMS for idle pulley MS, this SMS, after the AAI_PAG-ADV sending indicating positions renewal, is included in AAI_RNG-RSP message by BS.After transmission has the AAI_RNG-RSP of SMS, BS permits CDMA with active mode and distributes A-MAPIE, to receive the AAI_MSG-ACK as the confirmation for down link SMS.CDMA distributes the MCRC of A-MAPIE and uses RAID for finding range and mask designator to carry out mask process, and wherein, it is identical that this RAID and the CDMA of the AAI_RNG-REQ message sent at MS distribute the RAID carrying out mask process in A-MAPIE.

After BS transmission has the AAI_RNG-RSP of SMS, BS starts timer SMS_confirm_resource_alloc_timer (SMS confirms Resourse Distribute timer), and the CDMA permitting going to MS distributes A-MAPIE.When MS receives the AAI_RNG-RSP with SMS, MS starts timer SMS_confirm_resource_waiting_timer (SMS confirms resource waiting timer), and waits for that CDMA distributes A-MAPIE to send AAI_MSG-ACK.

If MS has the data that will send for short message, and this MS is in idle pulley, then this MS can use RNG-REQ46 to carry out location updating initiatively, and SMS is comprised into its part.Fig. 4 shows this situation.In this example, 45, complete the range finding based on coding, make these stations be ready for communication.Distance measurement request signal can adopt and distribute form A-MAPIE (for the RAID1 that finds range and mask designator) with the AAI_RNG-REQ of SMS at CDMA.Base station can use conventional RNG-RSP47 to reply, or base station can comprise short message at its RNG-RSP, if this base station has the queuing short message that will send.

In a particular example, BS uses AAI_RNG-RSP message to send SMS to MS in the downlink.SMS from the MS under idle condition can be included in AAI_RNG-REQ message.Such as, this can use range finding object indication bit #1=1 (" Idle Mode Location renewal ") to indicate.If the uplink resource for RNG-REQ message is not enough to send the AAI_RNG-REQ comprising SMS, then RNG-REQ segmentation method can be used to carry out segmentation to AAI_RNG-REQ.

When MS is in its idle condition, BS receives SMS by AAI_RNG-REQ message from this MS.After receiving SMS, BS can use AAI_RNG-RSP message to reply.This can be used as the confirmation of SMS.

In existing system, in physical layer, SMS and MMS is encrypted.When these message are specially configured as carrying SMS or MMS, above-mentioned functions can be realized.In 802.16m, RNG-REQ and RNG-RSP message is not encrypted.Generally, the control message carried in the TLV of RNG message is insensitive.This can use application layer (such as, SMS infill layer mechanism or carry out application encipher in another way) to compensate.More higher-layer encryption can be used to be encrypted the actual SMS part entrained by the TLV of RNG message, and without the need to being encrypted RNG message in physical layer.

In 802.16 examples discussed above, RNG message is a part for one group of MAC (media interviews control) control message.

These message are carried in the payload of MACPDU (protocol Data Unit).All MAC control message start with message type field, and can comprise other field.The form of control message is provided in table 1 below.

Field	Size	Remarks
			Control message type	8	REQ＝4，RSP＝5
Retain	8	Value is zero
			The information of TLV coding	Variable	Control message

Table 1

In Table 1, the Part I of MACPDU is type indicator.Be assigned with 8 bits.For RNG-REQ, type is numbering 4.For RNG-RSP, type is numbering 5.Use other type number to provide more eurypalynous MACPDU.Ensuing 8 bits of this message are zero.After this header, MACPDU comprises TLV data.As described below, TLV can have different sizes or length, and can use the special mode allowed by TLV combination in a single message.TLV is intended for for control message transparent user, and guarantees the smooth operation of system.

In 802.16m, the range finding using RNG-REQ and RNG-RSP is so a kind of process: obtain correct time migration, frequency shift (FS) and power adjustment, the transmission of MS is alignd with BS, and makes within the scope of suitable threshold level, receive these transmission.In addition, when mobile radio station moves, range finding is also used to establish the position of mobile radio station everywhere.

Ranging message is for maintaining the quality of the wireless communication link at physical layer place.Use different message for up link and down link, and basic structure is identical.Range finding allows power and the distribution of system call interception time and Frequency Synchronization and subcarrier and subchannel.For the carrier wave that each between each base station and the mobile radio station of registration is supported, perform range finding termly.

Ranging message is a part for the basic messae of system.Register different from broadcast channel and user, ranging message is directed to the particular B S that specific registered MS and this MS registers to it.Different from Traffic Channel, these basic messae processing control information and system configuration.

Distance measurement request (RNG-REQ) message is sent when initialization by MS and sends termly, to determine the change of network delay and request transmitting power, downlink burst profile (profile) or other system operating parameters.Initialization refers to that MS seeks to obtain for the access of network at first, and carries out time of registering to base station.Can permit sending RNG-REQ message in the time interval in initial range finding and data.The TLV field portions of this message environmentally changes, and can there is more than one TLV field in single RNG-REQ message.

TLV field can to comprising that burst profile, MAC Address, range finding are abnormal, capacity of equipment and identifier, base station identifier, handover request, network reentry request, emergency calling process, paging control message, regularly, the information of delay and retry parameter, power control and management message etc. encodes.All these parameters are all aimed at system, and the identification of MS or operation in attention location system.All these message do not relate to the information will transmitted to user or application layer.Generally, system manages to prevent user from checking these message, otherwise, the attentiveness of the information that interference user sends to other user for him or receives from other user by these message.

Ranging response (RNG-RSP) message has the similar type of the TLV parameter that it can send.These TLV parameters can comprise timing adjustment information, frequency, channel, subchannel and delay distribution, various timer, time slot and frame number, the device number of base station and modulator-demodulator and address and paging parameters etc.As request message, the TLV for response message also relates to controling parameters and equipment operating.

Using TLV for the message between user, allowing almost sending short user message any time when the mode of operation without the need to changing MS.Ranging message shows following advantage: can send these message when needs inactive connects, and almost can send these message any time.In order to provide this function, short user message is identified uniquely, and BS and MS is all adapted to be this message of identification and correspondingly processes this message.

TLV is an example of message encoding format.In addition, embodiments of the invention can be adapted to be other coded format for comprising ASN1.In multiple described embodiment of the present invention, short user message is placed in Optional Field.Subsequently, can comprise or do not comprise short user message and do not affect other function.In other words, when using Optional Field, when resolving this message, the presence or absence of short user message will not affect the parsing of this message.
