Description

Data communications method in the mobile radio system
Technical field
The present invention relates to transmit and receive the method for data, especially, relate to the data communications method in mobile radio system.
Background technology
In BWA, mobile subscriber station (MSS) is allowed to enter idle pulley to save power.When moving between the base station in identical paging zone, the MSS that is among the idle pulley does not need to carry out handover procedure.Usually, carrying out handover needs MSS to transmit at uplink direction during idle pulley.Because MSS needn't send the result of base station (BS) to, can save power.
The MSS that is arranged in a paging group is made up of a plurality of base stations.The area of coverage that is covered by paging group is known as paging zone.Identical paging cycle and paging offset value shared in the base station of the paging group in paging zone.
MSS transmits request message, and request enters idle pulley to BS.BS sends one then and permits the response message that MSS enters idle pulley, and in this response message, BS comprises paging group identifier, paging cycle value and paging offset value.Can make and spend register requirement (DREG-REQ) message and generate this request.
Respond this request, BS provides a response message to enter idle pulley to permit MSS.This response message comprises the paging offset of paging group identifier, paging cycle and BS.This response can make and spend the generation of log-in command (DREG-CMD) message.
In addition, media interviews control (MAC) address that BS will enter the MSS of idle pulley offers other BS of paging group, make MSS can be during idle pulley paging receiving message.
During idle pulley, BS is with official hour interval (being also referred to as paging cycle) broadcast, and inquiry MSS wishes to remain in the idle pulley or stops idle pulley, and perhaps whether MSS must carry out range operation.Simultaneously, BS can transmit beep-page message with the notice MSS have the down link data that is used for MSS.
Idle pulley can or stop by MSS or by BS.If MSS must transmit data at uplink direction, MSS can at any time stop idle pulley.On the other hand, if there is downlink traffic from BS, BS removes to stop idle pulley via beep-page message notice MSS, so that MSS can receive data.In addition, if be in the MSS among the idle pulley because all reasons can not be with official hour gap or paging cycle from BS paging receiving message, such as, moving to another paging zone, MSS stops idle pulley.
Here, as long as MSS needn't receive any downlink traffic and/or transmit data at uplink direction, the MSS that is among the idle pulley need not to carry out handover, just can freely roam in the border of paging zone.
If via the downlink traffic of beep-page message notice existence from BS, MSS stops idle pulley and re-registers/reenter network, and receiving downlink data.In addition, as a part of carrying out range operation, MSS makes BS upgrade position and the effective MSS information table of MSS.On the other hand, if MSS receives the order of not carrying out any operation via beep-page message, this MSS remains in the idle pulley.
But, if MSS must transmit data at uplink direction, if perhaps MSS moves to different paging zones, BS notice other this MSS of BS in paging group in this paging group no longer is among the identical paging zone, thereby, deletion corresponding M SS the table of the MSS among being in idle pulley.
If MSS moves to another paging zone, perhaps need to send to the BS that during idle pulley, occurs, corresponding M SS stops idle pulley, and must be with the new BS registration of new paging group.When registering with new BS, MSS must experience the registration process that starts anew, with the identical registration process of initial registration process to previous network.Therefore, MSS enlarge more power with new network registry, and simultaneously, experience a lot of times of this registration process consumption.
In addition, after moving to new paging group, if MSS wishes to keep the idle mode information of previous paging group, with new network registry after, MSS must be via MAC control messages request idle pulley.After this, the BS of new paging group provides a response to idle mode request.Equally, above-mentioned step makes to be increased aspect the MAC signaling, thereby increases power consumption.
Fig. 1 illustrates MSS and stops idle pulley and turn back to normal mode with the receiving downlink business.Here, each request that enters idle pulley of generating by MSS of MSS enters idle pulley.In addition, even MSS enters idle pulley to each order from BS, MSS stops idle pulley, and turns back to normal mode with the receiving downlink business.
With reference to figure 1, MSS goes registration (S10) via DREG-REQ and DREG-CMD and BS (BS1-master BS).After MSS entered idle pulley, main BS had entered idle pulley (S11) via paging announcement notice other this MSS of BS in identical paging group.In the paging announcement, main BS comprises media interviews control (MAC) address of MSS.Each BS of paging receiving announcement registers the MAC Address of MSS in its paging table.This paging table is to be shared by all BS in this paging zone.
Though be among the idle pulley, data can be sent to MSS.In order to receive this data, MSS must exit from idle mode.Therefore, when having downlink traffic, main BS transmits a paging announcement to notify BS all in paging group, and data must be transmitted to MSS (S12).Therefore, each BS uses the MAC Address that provides from main BS during paging interval to transmit a beep-page message to MSS (S13).
MSS is from each BS paging receiving message of paging group.If from one of BS, that is, the action code that BS#3 receives is set to " 10 ", and its expression initial network enters, and MSS carries out with BS#3 range operation and initial network and enters step (S14 and S15).Here, range operation comprise from MSS distance measurement request (RNG-REQ) message and from ranging response (RNG-RSP) message of BS.After MSS acquisition initial network entered, BS#3 sent down link data to MSS (S16).
Save power and be not limited to idle pulley.Except idle pulley, as the another kind of method of saving power, MSS can enter park mode to save power.For MSS enters park mode, MSS sends a request that enters park mode to BS via sleep request (MOB-SLP-REQ) message.BS sends one via dormancy response (MOB-SLP-RSP) message then and permits the response message that MSS enters park mode.MOB-SLP-REQ and MOB-SLP-RSP message comprise multiple information, such as time started, the maximum/minimum sleep interval (is unit with the frame) of park mode with listen at interval.
At the end of sleep interval, BS transmits traffic indication (MOB-TRF-IND) message and whether has any downlink traffic with notice MSS.If be not used in the downlink traffic that MSS receives, this MSS can turn back to park mode.But if there is down link data, this MSS turns back to normal mode and removes receiving downlink data.
Fig. 2 illustrates MSS and stops park mode and turn back to normal mode with the receiving downlink business.Here, each request that enters park mode of generating by MSS of MSS enters park mode.In addition, even MSS enters idle pulley to each order from BS, MSS stops idle pulley, and turns back to normal mode with the receiving downlink business.
With reference to figure 2, MSS sends a request that enters park mode to BS (S2-0) via MOB-SLP-REQ message.In response, BS sends MOB-SLP-RSP message to MSS (S2-1).In MOB-SLP-RSP message, comprise time started (M) such as park mode, maximum/minimum sleep interval (N1, N2) and listen to the information of (LI) at interval.
MSS enters park mode according to the minimum sleep interval (N1) that is provided with in S20 and S21, and BS transmits MOB-TRF-IND message during listening to interval LI (S2-2).Whether BS exists any data (negating/affirm) that receive for MSS via MOB-TRF-IND message instruct MS S.In addition, MSS listens to during LI or wakes up whether there is any down link data to check from dormancy.If there is not down link data, it is by " negating " expression, and this MSS turns back to park mode.But after listening at interval, sleep interval or sleep window size are doubled according to predetermined sleep window method to set up.
If BS receives data to send MSS to during sleep interval, BS stores data in the memory space of regulation, and waits for up to the next one and listening at interval that on its time, MSS is apprised of data (S2-3) via MOB-TRF-IND message.After this, MSS wakes up from park mode, and turns back to normal mode, so that receive data (S2-4).
In normal mode, if Internet Protocol (IP) grouping (data) is received by MSS, router sends the IP grouping to MSS via the base station.In the edition 4 of IP (IPv4), router uses ARP, and in the version 6 of IP (IPv6), this router uses contiguous find (ND).In other words, when sending the IP grouping to MSS, router uses ARP and ND agreement to find the target link layer address (for example, MAC Address or ethernet address) corresponding to the IP address of MSS.ARP is to be link layer address with the IP address modification, the IPv4 agreement of using in the time of such as MAC Address or ethernet address.
In addition, the ND agreement is the IPv6 address that is used for the link layer address of definite contiguous link.The variation of address takes place when producing IP packet header and link layer address head.Thereby, in the IP of output grouping address modification takes place only.
Traditionally, do not stipulate clearly how BS transmits or broadcast request or contiguous imploring to MSS.More particularly, in the specific role or the operation that in transmission request/vicinity is implored to the process of MSS, clearly do not define during the normal mode as BS.
In addition, perhaps at park mode or in idle pulley, MSS is the interval/cycle received signal to stipulate only.Therefore,, router gives MSS, when MSS is in park mode or idle pulley, because MSS can't respond ARP request or contiguous imploring going wrong at the fixed time before if must transmitting the data of reception.Therefore, target MSS can't send response, causes transmitting failure.Based on this problem, MSS might not receive this data.
Just as discussed above, this problem is present in from router data is sent to the process of MSS.Especially, because in the power-saving park mode or idle pulley of MSS, because MSS can't receive before preset time, the data that receive on router can not be received by MSS.Therefore, these data always are not transmitted to MSS.

Embodiment
To at length be introduced the preferred embodiments of the present invention now, the accompanying drawing illustrated that its example is being followed.As possible, run through the identical reference number of this accompanying drawing and will be used to relate to identical or similar part.
When entering idle pulley, MSS gives network entity via the dialog information that request message transmits MSS.Network entity for example can be base station, paging controller, IAD or base station controller.This dialog information is the tabulation of the dialog information of the MSS that keeps of MSS recommendation network entity.Especially, the MSS dialog information of recommending relates to network and enters relevant service and operation information again and enter from the network in idle pulley future accelerating again.
In addition, this request message comprises by MSS request and removes to enter idle pulley.For example, this request message is register requirement (DREG-REQ) message.In addition, this request message comprises the preferred dialog information that MSS wants network entity to keep.More particularly, this dialog information comprises such as security information, Internet Protocol (IP) address information, MSS performance, managing connection identification and is the information of indispensable information to keeping the network service.
Receiving the dialog information of recommendation (perhaps, the dialog information table) afterwards, this network entity selects it to judge the dialog information that keeps.After this, the response message of the network entity of the selected dialog information of this network entity notice MSS.The dialog information of this selection can be the dialog information with the recommendation that transmits from MSS identical, different or its combination.Equally, the dialog information of this selection comprises the dialog information that a row network entity is selected, so that certain MSS serves and following MSS of operation information quickening enters from idle pulley again by keeping.In addition, the dialog information of this selection is used to guarantee actual and effective service flow process between MSS and network entity.
In addition, this response message comprises the response that enters idle pulley by the MSS request.For example, this request message is log-in command (DREG-CMD) message.In this response message, this network entity comprises the dialog information of selection.
During idle pulley, if there is the downlink traffic of MSS, this network entity transmits the MSS that a beep-page message is given receiving downlink data, and to be included in this beep-page message be the dialog information of selecting.Normally, can periodically or with official hour transmit this beep-page message at interval.After this, the network entity in identical paging group is shared the dialog information of selecting mutually via backbone network.Therefore, when MSS stopped idle pulley and reenters this network, MSS can walk around some program steps that need in reentering this network.As previous explanation, the dialog information of keep being selected by network entity enters quickening again becomes possibility.This program step comprises that for example, those steps except that can sharing with other network entity simultaneously are such as IP address and/or security information.
If MSS moves to another paging group and need the position to upgrade, the new network entity in another paging group receives the dialog information of selecting from the network entity of previous paging group.The network entity of previous paging group is the network entity that keeps the MSS dialog information of latest update.The dialog information of the selection that the new network entity of another paging group will receive from previous paging group then sends MSS to.Subsequently, in the process of upgrading the MSS position, MSS reenters new network, so that lastest imformation.In brief, can carry out the position of MSS under based on the environment of paging zone identifier and upgrade, wherein for example when a paging zone identifier moves to another paging zone identifier, upgrade as MSS.
In addition, can carry out the position renewal of MSS based on the time.In other words, the position renewal based on timer comprises scheduling, MSS and network implementation position renewal whereby.For example, be arranged between MSS and the network entity with per 10 seconds, do not considered whether whether MSS moves the position of upgrading per 10 seconds renewal MSS based on previous position if upgrade scheduling based on the position of timer.
When MSS received a plurality of paging group identifier via beep-page message when, MSS request corresponding network entity position was upgraded.In upgrading the process of position, MSS will permit the identifier of the network entity that idle pulley enters and wish that the paging group identifier that permission MSS remains on the paging group in the idle pulley sends network entity in the paging group formerly.After this, corresponding network entity transmits information via response message, gives position updating request such as paging group identifier, paging cycle value and paging offset value, and MSS remains in the idle pulley after moving to different paging groups to allow.
Following table 1 illustrates the example of message parameter of the dialog information table of a MSS.
[table 1]
Title Type Length Value
The network settings of accelerating Nn 1 For each bit position, value " 0 " expression does not wish that the relevant message of entrance management again of preserving, value " 1 " expression hope goes the message of entrance management again of preserving.The relevant overview bit #3 of overview bit #2:REG-REQ/RSP management that the overview bit #1:PKM-REQ/RSP management that bit #0:SBC-REO/RSP management is relevant is relevant: the overview bit #4 that network address information is relevant: overview bit #5～6 that the network service is relevant: reservation
The message parameter of table 1 is included in the message with the TLV form, and when can represent to stop idle pulley with the bit mapping format, can walk around network registration process.In an embodiment of the present invention, above-mentioned operation table is shown " the Netz etup_flag of quickening ".
Fig. 3 illustrates when MSS constraint down link occurring during idle pulley when the one embodiment of the present of invention with respect to signal processing.Fig. 3 illustrates and be used for the process that MSS stops idle pulley when having downlink traffic.
MSS enters request the request message of idle pulley via going register requirement (DREG-REQ) message to send first network entity (S10) to.Being included in the request message is the preferred dialog information of MSS, and MSS recommends to be used to accelerate following network entity that enters reservation again and gives network.As explained above, this network entity for example can be base station, paging controller, IAD or base station controller.The preferred dialog information of this MSS comprises such as security information, Internet Protocol (IP) address information, MSS performance, managing connection identification and is the information of indispensable information to keeping the network service.The dialog information message of this recommendation can be to be similar to the form of table 1.
For the cause of explaining, the network entity that receives preferred dialog information from MSS is confirmed as first network entity.In addition, second network entity can be confirmed as the MSS searching from the reentrant network entity of idle pulley.After receiving request message, first network entity is notified at least one or the every other network entity that has identical paging identifier in this paging group via one or more key channel radios one, so that corresponding M SS can be added to each network entity (S20) in paging group.After this, respond this request message, first network entity sends the dialog information of selecting to corresponding M SS (S30) via going to register response command (DREG-CMD).The dialog information of this selection comprises that the MSS to accelerating future enters useful certain MSS service and operation information again from idle mode network.The dialog information of this selection can be the dialog information of a column selection, and it can be identical, different with the preferred dialog information by MSS request or its combination.In addition, in the process of transmission DREQ-CMD, can comprise other information, such as paging cycle, paging offset and paging identifier.DREG-CMD permits order or the message that MSS enters idle pulley according to request.
In case receive DREG-CMD from first network entity, this MSS enters idle pulley.During idle pulley, MSS can be with the time slot of regulation or at interval from the first network entity paging receiving message (S40).Whether this beep-page message comprises multiple information, such as having any downlink traffic or when stop idle pulley.
During idle pulley, MSS might move in the paging group with identical paging group identifier, perhaps another network entity in the paging group with a plurality of paging group identifiers (being called hereinafter, " second network entity ").If MSS moves to second network entity (S50) in the identical paging group with identical paging identifier, MSS is to receive one or more beep-page messages (S60) with the identical paging cycle and the paging offset that receive from first network entity from second network entity.
When the down link business arrives at first network entity, and first network entity circulates a notice of downlink traffic to MSS (S70), and first network entity sends dialog information in this paging group together with the downlink traffic that exists other network entity (S80) via backbone network.
After first network entity receives the dialog information of selection, second network entity will comprise the dialog information of selection and exist the beep-page message of downlink traffic to send MSS (S90) to.This MSS sends the identifier (it is permitted MSS and enters idle pulley) of first network entity to second network entity (S100) via distance measurement request message then.
In case receive the sign of first network entity, second network entity is circulated a notice of this MSS of first network entity and is arranged in its area of coverage, and asks first entity to go to transmit the dialog information (S110) of the corresponding M SS that is kept by first network entity.
First network entity meets this request (S120) by transmitting the dialog information that keeps via key channel.In addition, second network entity is given MSS (S130) via the table that ranging response message transmits the current dialog information that is kept by second network entity.Therefore, when MSS carries out this network reentrant the time, can skip and enter some program step that this network needs again.In other words, because second network entity keeps MSS service and the operation information of determining, in the process that enters this network again, do not need identical information.Simultaneously, MSS is received in the process that reenters this network the program step that can be skipped by MSS via ranging response message.
Based on the information that provides from second network entity, network takes place enter or enter process (S140).The program step of this network registry only gives some instances, and for example can comprise negotiations process, security process, registration process, the IP address capture process of MSS performance.In addition, in order to set up the connection that is used for Data Receiving, MSS carries out necessary process with the network process of entering.Be used for after process that network enters (perhaps entering) and Data Receiving again finishes, second network entity will send MSS (S150) to from the down link data that first network receives.
When having downlink traffic during idle pulley when, step (S10-S150) is described in the operation in this network.If there is uplink traffic in the MSS that is among the idle pulley, can from operation, get rid of some step (S70, S80, S90 and S 150).
Fig. 4 illustrates when MSS request and enters idle pulley, and the signal processing of request network entity when keeping dialog information.As an alternative embodiment of the invention, the process that relates in the process of the position of the MSS among renewal is in idle pulley has been described after MSS moves to another paging group.
With reference to figure 4, MSS enters request the request message of idle pulley via going register requirement (DREG-REQ) message to send first network entity (S210) to.Being included in the request message is the preferred dialog information of MSS, and MSS recommends to be used to accelerate following network entity that enters reservation again and gives network.This network entity can be BS or paging controller.As explained above, this network entity for example, can be base station, paging controller, IAD or base station controller.The preferred dialog information of this MSS comprises such as security information, Internet Protocol (IP) address information, MSS performance, managing connection identification and is the information of indispensable information to keeping the network service.This preferred dialog information message can be to be similar to the form of table 1.
The sign of first network entity and second network entity is described with respect to Fig. 3 as explained above.After receiving request message, first network entity is notified to the every other network entity that has identical paging identifier in this paging group via key channel radio one, so that add corresponding M SS in paging group each network entity (S220).After this, respond this request message, first network entity sends the dialog information of selecting to corresponding M SS (S230) via going to register response command (DREG-CMD).The dialog information of this selection comprises that the MSS to accelerating future enters the useful MSS that determines service and operation information again from idle mode network.The dialog information of this selection can be the dialog information of a column selection, and it can be identical, different with the preferred dialog information by MSS request or its combination.In addition, in the process of transmission DREQ-CMD, can comprise other information, such as paging cycle, paging offset and paging identifier.DREG-CMD permits order or the message that MSS enters idle pulley as requested.
In case receive DREG-CMD from first network entity, this MSS enters idle pulley.During idle pulley, MSS can be with the time slot of regulation or at interval from the first network entity paging receiving message (S240).Whether this beep-page message comprises multiple information, such as having any downlink traffic or when stop idle pulley.
During idle pulley, MSS might move in the paging group with identical paging group identifier, perhaps another network entity in the paging group with a plurality of paging group identifiers (" second network entity " hereinafter).If MSS moves to second network entity (S250) in the identical paging group with identical paging identifier, MSS with the identical paging cycle that receives from first network entity and paging offset from the second network entity paging receiving message (S260).
If this cell footprint is designed so that network entity and only can belongs to a paging group that the network entity that moves to the paging group with an above paging group identifier refers to the network entity that for example moves between two paging groups.
In this, this MSS learns second network entity except that first paging group, also belongs to second paging group with different paging group identifiers.Second network entity is via the paging group identifier of beep-page message transmission corresponding to its paging group that belongs to.If cell footprint is designed so that network entity and can only belongs to a paging group, might for example transmit the paging group identifier of contiguous paging group.
After receiving the beep-page message with different paging group identifiers, this MSS upgrades (S270) via distance measurement request message from the second network entity request position.Except position updating request, this distance measurement request message can comprise other information, such as, the identifier of first network entity (it is permitted MSS and enters idle pulley), the paging group identifier of this second paging group and the paging cycle of wanting.If this cell footprint is designed so that network entity and can only belongs to a paging group, when MSS moves to another paging group, this MSS can't be via previous paging information paging receiving message, just in this, for example, this MSS upgrades to new network entity request position.
After MSS receives position updating request, the second network entity request, first network entity transmits the dialog information (S280) of the current selection that is kept by first network entity.First network entity dialog information of the selection of the current reservation of each request transmission is then given second network entity (S290).
Even after the position of MSS had been updated, second network entity transmitted the tabulation (S300) of dialog information of the reservation of this MSS via ranging response message.Here, at this ranging response message, other information is such as the second paging group identifier and corresponding paging cycle and paging offset value.Therefore, corresponding M SS can be according to the second paging group identifier paging receiving message.In addition, second network entity transmits the current dialog information that is kept by second network entity via ranging response message and gives MSS.Therefore, when MSS carries out this network reentrant the time, can skip and enter some program step that this network needs again.In other words, because second network entity keeps MSS service and the operation information of determining, in the process that enters this network again, do not need identical information.Simultaneously, MSS is received in the process that enters this network again the program step that can be skipped by MSS via ranging response message.
After first network entity receives the dialog information of reservation via ranging response message, this MSS can carry out the network that needs and enter process, so that no longer upgrade actual or out-of-date information (S310).Second network entity uses backbone network to go to notify this MSS of another network entity of first paging group to reorientate to different paging groups, and goes to register the information relevant with MSS with deletion (S320).Simultaneously, second network entity notifies the network entity of second paging group to add the information relevant with MSS via backbone network.With regard to MSS, MSS with the interval of regulation from the second paging group paging receiving message and keep idle pulley (S330).
As mentioned above, if the position of MSS by from first network entity updates to second network entity, the down link data that is sent to MSS is received by second network entity, second network entity, rather than first network has upgraded the position of MSS.
Fig. 5 illustrates the signaling process of another embodiment of the present invention.Here, downlink traffic is present in the environment, wherein since as network entity via the result who goes log-in command (DREG-CMD) information order MSS to enter idle pulley, MSS enters idle pulley.
In this embodiment, give network entity different with the previous embodiment that enters idle pulley with the MSS request of transmitting, this network entity order MSS enters idle pulley.Transmit the order that enters idle pulley via DREG-CMD message here.DREG-CMD comprises the duration (REQ-duration) of the action code that is arranged on the 0x05 and needs, and its regulation MSS enters the time (S410) of idle pulley.
More particularly, first network entity transmits the preferred dialog information of MSS via DREG-CMD message request MSS.DREG-REQ comprises that regulation is by itself or MSS time of transmitting request message thereon.After first network entity receives DREG-CMD, MSS sends first network (S420) to via the preferred dialog information of going register requirement (DREG-REQ) message with the MSS of network entity request.The preferred dialog information of this MSS comprises such as security information, Internet Protocol (IP) address information, MSS performance, managing connection identification and is the information of indispensable information to keeping the network service.The preferred dialog information of this MSS is that MSS recommends to be used to accelerate the row dialog information that following network entity that enters reservation is again given network.
As explained above, with respect to Fig. 3 sign of first network entity and second network entity as mentioned above.After receiving request message, first network entity is notified to the every other network entity that has identical paging identifier in this paging group via key channel radio, so that corresponding M SS can be added to each network entity (S430) in paging group.After this, respond this request message, first network entity sends the dialog information of selecting to corresponding M SS (S440) via going to register response command (DREG-CMD).The dialog information of this selection comprises that the MSS to accelerating future enters useful some MSS service and operation information again from idle mode network.The dialog information of this selection can be the dialog information of a column selection, and it can be identical, different with the preferred dialog information by MSS request or its combination.In addition, in the process of transmission DREQ-CMD, can comprise other information, such as paging cycle, paging offset and paging identifier.DREG-CMD permits order or the message that MSS enters idle pulley according to request.
In case receive DREG-CMD from second network entity, this MSS enters idle pulley.During idle pulley, MSS can be with the time slot of regulation or at interval from the first network entity paging receiving message (S450).Whether this beep-page message comprises multiple information, such as having any downlink traffic or when stop idle pulley.
During idle pulley, MSS might move in the paging group with identical paging group identifier, perhaps another network entity in the paging group with a plurality of paging group identifiers (" second network entity " hereinafter).If MSS moves to second network entity (S460) in the identical paging group with identical paging identifier, MSS with the identical paging cycle that receives from first network entity and paging offset from the second network entity paging receiving message (S470).
When the down link business arrives at first network entity, and when first network entity is circulated a notice of downlink traffic to MSS (S480), first network entity sends dialog information in this paging group together with the downlink traffic that exists other network entity (S490) via backbone network.Here, the dialog information that sends this selection of other network entity in paging group to via key channel can be the dialog information of a column selection.
After first network entity receives the dialog information of selection, second network entity will comprise the dialog information of selection and exist the beep-page message of downlink traffic to send MSS (S500) to.This MSS sends the identifier (it is permitted MSS and enters idle pulley) of first network entity to second network entity (S510) via distance measurement request message then.
In case receive the sign of first network entity, second network entity is circulated a notice of this MSS of first network entity and is arranged in its area of coverage, and asks first entity to go to transmit the dialog information (S520) of the corresponding MSS that is kept by first network entity.
First network entity meets this request (S530) by transmitting the dialog information that keeps via key channel.In addition, second network entity is given MSS (S540) via the tabulation that ranging response message transmits the current dialog information that is kept by second network entity.Therefore, when MSS carries out this network reentrant the time, can skip and enter some program step that this network needs again.In other words, because second network entity keeps MSS service and the operation information of determining, in the process that enters this network again, do not need identical information.Simultaneously, MSS is received in the process that enters this network again the program step that can be skipped by MSS via ranging response message.
Based on the information that provides from second network entity, network takes place enter or enter process (S550).The program step of this network registry only gives some instances, and for example can comprise negotiations process, security process, registration process, the IP address capture process of MSS performance.In addition, in order to set up the connection that is used for Data Receiving, MSS carries out necessary process with the network process of entering.Be used for after process that network enters (perhaps entering) and Data Receiving again finishes, second network entity will send MSS (S560) to from the down link data that first network receives.
Step (S410-S560) is described the operation in this network when having downlink traffic during idle pulley when.If there is uplink traffic in the MSS that is among the idle pulley, can from operation, get rid of some step (S480, S490, S500 and S560).
Fig. 6 illustrates the signal processing of an alternative embodiment of the invention.Here, downlink traffic is present in the environment, wherein since as network entity via the result who goes log-in command (DREG-CMD) information order MSS to enter idle pulley, MSS enters idle pulley.In addition, this embodiment is described in MSS and moves to after another paging group, the process that relates in the process of the MSS position among renewal is in idle pulley.
In this embodiment, give network entity different with the previous embodiment that enters idle pulley with the MSS request of transmitting, this network entity order MSS enters idle pulley.Here, the order that enters idle pulley is transmitted via DREG-CMD message.DREG-CMD comprise the time that the action code that is arranged on the 0x05 and regulation MSS enter idle pulley needs duration (REQ-duration) (S610).
More particularly, first network entity goes to transmit the preferred dialog information of MSS via DREG-CMD message request MSS.DREG-REQ comprises that regulation is by itself or MSS time of transmitting request message thereon.After first network entity receives DREG-CMD, MSS sends first network (S620) to via the preferred dialog information of going register requirement (DREG-REQ) message with the MSS of network entity request.The preferred dialog information of this MSS comprises such as security information, Internet Protocol (IP) address information, MSS performance, managing connection identification and is the information of indispensable information to keeping the network service.The preferred dialog information of this MSS is that MSS recommends to be used to accelerate the row dialog information that following network entity that enters reservation is again given network.
As explained above, as mentioned above with respect to the sign of Fig. 3 first network entity and second network entity.After receiving request message, first network entity is notified to the every other network entity that has identical paging identifier in this paging group via one of key channel radio, so that corresponding M SS can be added to each network entity (S630) in paging group.After this, respond this request message, first network entity sends the dialog information of selecting to corresponding M SS (S640) via going to register response command (DREG-CMD).The dialog information of this selection comprises that the MSS to accelerating future enters the useful MSS that determines service and operation information again from idle mode network.The dialog information of this selection can be the dialog information of a column selection, and it can be identical, different with the preferred dialog information by MSS request or its combination.In addition, in the process of transmission DREQ-CMD, can comprise other information, such as paging cycle, paging offset and paging identifier.DREG-CMD permits order or the message that MSS enters idle pulley according to request.
In case receive DREG-CMD from first network entity, this MSS enters idle pulley.During idle pulley, MSS can be with the time slot of regulation or at interval from the first network entity paging receiving message (S650).Whether this beep-page message comprises multiple information, such as having any downlink traffic or when stop idle pulley.
During idle pulley, MSS might move in the paging group with identical paging group identifier, perhaps another network entity in the paging group with a plurality of paging group identifiers (" second network entity " hereinafter).If MSS moves to second network entity (S660) in the identical paging group with identical paging identifier, MSS is to receive one or more beep-page messages (S670) with the identical paging cycle and the paging offset that receive from first network entity from second network entity.
If this cell footprint is designed so that network entity and can only belongs to a paging group that the network entity that moves to the paging group with an above paging group identifier refers to the network entity that for example moves between two paging groups.
In this, this MSS learns second network entity except that first paging group, also belongs to second paging group with different paging group identifiers.Second network entity is via the paging group identifier of beep-page message transmission corresponding to its paging group that belongs to.If cell footprint is designed so that network entity and can only belongs to a paging group, might for example transmit the paging group identifier of contiguous paging group.
After receiving the beep-page message with different paging group identifiers, this MSS upgrades (S680) via distance measurement request message from the second network entity request position.Except position updating request, this distance measurement request message can comprise other information, such as, the identifier of first network entity (it is permitted MSS and enters idle pulley), the paging group identifier of this second paging group and the paging cycle of wanting.If this cell footprint is designed so that network entity and can only belongs to a paging group, when MSS moves to another paging group, this MSS can't be via previous paging information paging receiving message, just in this, for example, this MSS upgrades to new network entity request position.
After MSS receives position updating request, the second network entity request, first network entity goes to transmit the dialog information (S690) of the current selection that is kept by first network entity.First network entity asks the dialog information of the selection of the current reservation of transmission to give second network entity (S700) at each then.
Even after the position of MSS had been updated, second network entity transmitted the table (S710) of dialog information of the reservation of this MSS via ranging response message.Here, in this ranging response message, other information is such as the second paging group identifier and corresponding paging cycle and paging offset value.Therefore, corresponding M SS can be according to the second paging group identifier paging receiving message.In addition, second network entity transmits the current dialog information that is kept by second network entity via ranging response message and gives MSS.Therefore, when MSS carries out this network reentrant the time, can skip and enter some program step that this network needs again.In other words, because second network entity keeps MSS service and the operation information of determining, in the process that enters this network again, do not need identical information.Simultaneously, MSS is received in the process that enters this network again the program step that can be skipped by MSS via ranging response message.
After second network entity receives the dialog information of reservation via ranging response message, this MSS can carry out the one or more networks that need and enter process, so that no longer upgrade actual or out-of-date information (S720).Second network entity uses backbone network to remove to notify another network entity of first paging group, and this MSS has been repositioned onto different paging groups, and goes to register the information relevant with MSS with deletion (S730).Simultaneously, second network entity notifies the network entity of second paging group to go to add the information relevant with MSS via backbone network.With regard to MSS, MSS with the interval of regulation from the second paging group paging receiving message and keep idle pulley (S740).
As mentioned above, if the position of MSS by from first network entity updates to second network entity, the down link data that is sent to MSS is received by second network entity, second network entity, rather than first network has upgraded the position of MSS.
Above argumentation relates to that MSS and network entity comprise and upgrade dialog information to accelerate MSS entering again from idle pulley for the operation/procedure of idle pulley in entering the process of network.Below discuss the operation of MSS before entering idle pulley, so as during idle pulley receiving downlink business effectively.
During normal mode, router uses target or object IP address to find MSS link layer address (for example, MAC Address or ethernet address), so that send data to MSS.In order to realize this, router sends addressing request to network entity.Here, in the edition 4 (IPv4) of IP, router transmits the ARP request, and in the version 6 (IPv6) of IP, router transmits contiguous imploring.
In one embodiment of the invention, after router receiver address request message, this network entity is broadcast to a plurality of MSS at network entity, and perhaps the transfer address request message is given each MSS seriatim.After this, this network entity receives response message from MSS, such as, arp response message or neighbor advertisement response message, and send this response message to router.In address request, can for example comprise MAC Address or ethernet address.From a plurality of MSS of receiver address request message, the MAC of MSS or ethernet address can mate MAC or the ethernet address that is included in the address request.Then, the MSS with MAC Address of coupling transmits response message to network entity via auxiliary management connection or common data pulse.
In addition, in an embodiment of the present invention, network entity can transmit the proxy ARP response message (perhaps, acting on behalf of neighbor advertisement) of MSS to router with dormancy/idle pulley.In other words, this network entity can directly respond for example proxy requests of MSS by router.For the network entity of this router of response, MSS comprises its IP address in MOB-SLP-REQ message or DREG-REQ message, and sends network entity to.In addition, be the time when entering dormancy/idle pulley by the network entity order, before entering dormancy/idle pulley, MSS offers network entity with its IP address.Embodiments of the invention are not limited to IPv4, but go for using the contiguous protocol of I Pv6 that finds.
In an embodiment of the present invention, this network entity uses proxy ARP or the contiguous agreement of finding of agency, makes data send network entity to when being in park mode or idle pulley as MSS.As previous argumentation, this network entity can be base station, paging controller, IAD or base station controller.In the figure, base station (BS) is used as the example of a network entity to describe embodiment.Among the embodiment formerly, this network entity transmits ARP or the contiguous message of being correlated with of finding is given MSS.In this process, if MSS is in dormancy or idle pulley, data can not arrive target MSS.But in this embodiment, this network entity can directly respond from the ARP request of this router or contiguous imploring.For this reason, this network entity must have IP address and the link layer address (MAC Address or ethernet address) of MSS.
In order to have this address, when MSS and network entity registration to enter park mode or idle pulley or by retrieval MSSIP address setting the time, network entity can obtain MSSIP address and link layer address.More particularly, when MSS transmitted the IP address via request message, network entity can obtain the IP address by directly receiving the IP address from MSS.In addition, network entity can go to use the current MSS that is retained in the IP address in the network entity to obtain the IP address by the request network entity.In other words, MSS does not transmit the IP address, and keeps it to be retained in IP address in the network entity.This network entity can also be by directly obtaining information to MSS request IP and link layer address.
Fig. 7 illustrates the link layer address acquisition procedure of router when MSS automatically enters park mode.With reference to figure 7, MSS transmits MOB-SLP-REQ message and enters park mode (S3-0) with request for network entity.In this request message, MSS comprises that its IP address is to allow network entity to go to respond the ARP request from the admissible future of router.Respond this request, network entity sends MOB-SLP-RSP message to MSS (S3-1).
In case receive response message from network entity, this MSS enters park mode for the duration of stipulating in MOB-SLP-RSP message.After this sleep interval, MSS wakes up receiving MOB-TRF-IND message from network entity for listening at interval (LI), and determines whether to receive any down link data (S3-2).If there is not receiving downlink data, this MSS reenters park mode for the sleep interval (2*N1) that increases.Here, after listening at interval, this sleep interval increases the amount (that is, previous sleep interval double) of a regulation.
Fig. 8 illustrates the link layer address acquisition procedure of router when MSS enters park mode owing to the result from the network entity order.With reference to figure 8, this process is similar to Fig. 7.But, in Fig. 8, replace providing MSS IP the address via request message, owing to be to determine to enter park mode by network entity in this embodiment, this MSS IP address is transmitted via informational message.It is for receiving DREG-CMD message with after entering idle pulley at MSS, the process that repeats to transmit DREG-REQ message and DREG-RSP message also is possible.In this case, will transmit MSS IP address via DREG-REQ message.
Fig. 9 illustrates the link layer address acquisition procedure of router when MSS automatically enters idle pulley.In Fig. 9, this MSS sends DREG-REQ message to first network entity, so that enter idle pulley, and in response, first network entity transmits DREG-CMD message and enters park mode (S4-0) to permit MSS.In DREG-REQ message, this MSS comprises its IP address to first network entity, makes when MSS is in idle pulley, and BS need not to relate to the ARP request that MSS just can respond router.
MSS had gone registration from first network entity (perhaps main BS) after, first network entity had entered idle pulley with this MSS and has been broadcast to every other BS (S4-1) in identical paging zone.The BS that receives this broadcasting adds this MSS information then and gives its paging table.
When router received the IP grouping, this router sent the ARP request to main BS, with the MAC Address (S4-2) of the target ip address of determining MSS.In response, because main BS has the essential IP address information of MSS, the arp response message that main BS will be used for MSS sends router (S4-3) to.
In case receive arp response message, router sends the IP grouping to main BS.After this, main BS transmits the paging announcement (S4-4) that there is the down link data that is used for MSS in notice all BS in paging zone.After receiving this paging announcement, the BS that has MSS in its cell footprint gives MSS (S4-5) with the paging cycle transmission beep-page message of regulation.
Figure 10 illustrates another embodiment of the present invention.This example illustrates the link layer address acquisition procedure of router when MSS enters park mode owing to the result from the network entity order.With reference to Figure 10, be similar to Fig. 9 about the process of between MSS and network entity, communicating by letter.But, in Figure 10, replace providing MSSIP the address via request message, owing to be to determine to enter park mode by network entity in this embodiment, this MSS IP address can be transmitted via informational message.It is for receiving at MSS after DREG-CMD message goes to enter idle pulley, and the process that repeats to transmit DREG-REQ message and DREG-RSP message also is possible.In this case, will transmit MSS IP address via DREG-REQ message.
In another embodiment of the present invention, this MSS request network entity keeps Convergence Sublayer information.Convergence Sublayer is layer 2 protocol typically, and it undertakes the responsibility of gathering and formaing high layer information, makes this high layer information to be handled by lower floor.
Figure 11 illustrates another embodiment of the link layer address acquisition procedure of router when MSS automatically enters idle pulley.With reference to Figure 11, the operation of this embodiment and process are similar to the process of Fig. 9.Therefore, the process identical with respect to the embodiment of Fig. 9 will be removed.
In this embodiment, this MSS sends DREG-REQ message to first network entity, so that enter idle pulley, and in response, first network entity transmits DREG-CMD message and enters park mode (S5-0) to permit MSS.In DREG-REQ message, MSS comprises that request is to keep Convergence Sublayer (CS) information.By making first network entity keep CS information, first network entity combines with downlink traffic at idle pulley, can need not to contact the request of MSS ground response from router.In fact, downlink traffic can more effectively be transmitted, and can use the resource of network better.As explained above, remaining process of this embodiment is identical with the process of Fig. 9.
In addition, Figure 12 illustrates an alternative embodiment of the invention.Here, this embodiment represents the link layer address acquisition procedure of router when MSS enters park mode owing to the result from the network entity order.With reference to Figure 12, be similar to the process of Figure 11 about the process of between MSS and network entity, communicating by letter.But, in Figure 12, replacing providing MSS IP the address via request message, this MSS sends request message to first network entity to keep CS information.This request can be via informational message or alternatively, transmits via DREG-REQ message.Remaining is identical with Figure 11 for this process.
