Abstract
The invention relates to the wireless communication field and discloses a paging method and a wireless network. The invention can ensure that the normal paging of terminals can be carried out even when relay stations are arranged in the network. In the invention, when receiving paging information from a terminal with idle mode, a base station or a relay station can carry out paging in the scope itself and send the paging information down step by step. When receiving the paging information from the terminal with idle mode, the base station or the relay station can directly send the paging information to a subordinate relay station, or can carry out paging in the coverage area of the base station or the relay station; if the responding information from the terminal is not received in a preset time limit, the paging information is sent to the subordinate relay station. When the base station or the relay station receives the location updating or network reentrance request from the subordinate relay station or the terminal, or when paging frequency reaches the maximum, the sending of the paging information is stopped. When receiving the information of stopping paging from a superior relay station or the base station, the relay station stops sending paging information.
Description
Technical field
The present invention relates to wireless communication field, particularly the control technology of idle mode terminals.
Background technology
Along with people growing to the broadband wireless communications demand, demand to wireless bandwidth becomes increasing, therefore more and more higher carrier frequency is used in the new agreement and wireless communication system, yet, owing to the decay of the radio wave increase along with frequency increases, therefore, high carrier frequency must be faced with the problem of high decay, uses high carrier frequency to limit the coverage of base station.In addition, in wireless communication system,, make that some regional wireless communication signals intensity is lower, be positioned at these regional communications of Mobile Terminals quality and will become very poor owing to electromagnetic path attenuation or building such as block at reason.
In order to increase the coverage of base station, improve the communication quality of signal strength signal intensity lower region, need to adopt relay station that the wireless communication signals between base station and the portable terminal is strengthened usually.Do not need wire transmission between relay station and the base station, only communicate by Radio Link, it is low therefore to have a cost of arranging net, and disposes simple advantage.Because the particularity (such as long and narrow zone) of some geographical environments when transmit at the station of in use continuing, can adopt a plurality of relay station cascades to carry out the multi-hop transmission manner.
The multi-hop wireless communication system structure that contains relay station as shown in Figure 1, among the figure, the base station is connected by optical cable or cable with core net, base station range is limited, can't directly cover portable terminal 1-4 region, but can pass through relay station 1-4, cover these zones.All do not have cable to be connected between each relay station and core net and the base station, wherein relay station 1 and relay station 2 be by Radio Link and base station communication, relay station 3 with and relay station 4 do not have DCL with the base station, but transmit by relay station 2.For portable terminal 3, the transfer of data that sends from the base station need be through 3 jumpings, and first jumping is arrived portable terminal 3 for relay station 2 arrives relay station 3, the three jumpings for relay station 3 to relay station 2, the second jumpings for the base station.For simplicity, relay station 2 and relay station 3 are called first and second of portable terminal 3 and jump relay stations.Consider the service relation between each base station, will jump relay station for next provides serving base station or relay station to be called the service station, is the service station of relay station 1 and relay station 2 as the base station, and relay station 2 is the service station of relay station 3 and relay station 4.If regard base station and relay station as in the topological network node, after data transmission link is set up, the upstream node that the service relay stations and the upper layer node thereof of relay station can be called this relay station is called downstream node with the next-hop node of this relay station until for the node of Terminal Service.
More than simple introduction has been carried out in the introducing and the effect thereof of relay station, the support to the terminal idle pulley describes to wireless communication system below.Provide the support of terminal idle pulley is a critical function of mobile communication system.Under idle pulley, terminal does not need to be registered to specific base stations, does not need to switch, and does not need to carry out all conventional operating process.Idle pulley provides a kind of mechanism, makes that terminal can be periodically by network side paging, and is unlikely to suspension.Provide and to save the electrical source consumption of terminal greatly, also saved the resource of system simultaneously the support of terminal idle pulley.Idle pulley is usually directed to following process: terminal access idle mode, terminal are carried out position renewal, network side paging terminal, and terminal exits from idle mode.After terminal is through with normal operation, can enter idle pulley; After entering idle pulley, in moving process, need carry out the position and upgrade, can dynamically know the state and the position of terminal to guarantee network side; When the business of terminal arrived, network side need be initiated the paging to terminal, requires terminal to exit from idle mode; After terminal exits from idle mode, can carry out network and reentry, enter normal mode.
Below with micro-wave access to global intercommunication (Worldwide Interoperability for MicrowaveAccess, abbreviation " WiMAX ") network is an example, to terminal access idle mode, terminal is carried out the position and is upgraded, base station calling terminal, terminal four processes that exit from idle mode are specifically described.
Terminal access idle mode:
As shown in Figure 2, in step 201, terminal sends de-registration request (DREG-REQ) message to its serving BS, comprise paging cycle, idle pulley in the message and need be information of its reservation etc., can also comprise the information such as number of times threshold value of skipping media interviews control (Medium Access Control is called for short " MAC ") Hash address.
Then enter step 202, after serving BS is received this message, access service network gateway (Access Service Network GateWay to network side, be called for short " ASN-GW ")/local paging controller (Paging Controller, be called for short " PC ")/datapath function module (Data Path Function, be called for short " DPF ") send data channel release request, wherein comprise sign (MSID), the Base Station Identification information such as (BSID) of terminal.
Then enter step 203, the data channel that the ASN-GW/PC/DPF of network side sends the base station is cancelled request and is responded, and sends data channel release response.
Then enter step 204 and 205, two steps and do not have fixing precedence relationship.In step 204, serving BS sends cancellation order (DREG-CMD) to terminal after receiving that data channel discharges response, wherein comprises parameters such as paging parameters, anchor paging controller sign, idle pulley reservation information.In step 205, serving BS return data passage discharges to be confirmed.
Terminal enters idle pulley after receiving and nullifying order.
Terminal is carried out the position and is upgraded:
Behind the terminal access idle mode, need carry out the position and upgrade.Specifically, when the condition of updating of terminal position triggers, perhaps receive when network side is notified its message of carrying out the position renewal, need carry out position updating process.The trigger condition of updating of terminal position comprises following four kinds of situations: terminal enters new paging zone, the idle pulley timer expiry of terminal, terminal closedown, the Hash Skip Counter (Hash jumping figure) of terminal surpasses Hash Skip Threshold (Hash jumping figure thresholding).When the condition of updating of terminal position triggers, the updating of terminal position process as shown in Figure 3:
In step 301, terminal sends position updating request to its at present synchronous base station, and this request is carried by distance measurement request (RNG-REQ) message, wherein comprises anchor paging controller sign.
Then enter step 302, receive that the base station of updating of terminal position request sends position updating request to the anchor paging controller of terminal, wherein comprise the sign of terminal, the information that Base Station Identification etc. are necessary.
Then enter step 303, after the anchor paging controller is received request, send the position to relevant base station and upgrade response.
After the base station received that response is upgraded in the position, then entering step 304 and 305, two steps not have the precedence relationship of fixing.In step 304, the base station generates the position and upgrades response message, and this information is carried by ranging response (RNG-RSP) message, wherein comprises position update mode (success or failure), if the position is upgraded successfully, then comprise paging information and other necessary information.In step 305, the base station is upgraded to anchor paging controller home position and is confirmed.
The network side paging terminal:
When trigger condition satisfied, anchor PC sent paging declaration (Paging Announce) need for all base stations of the paging group at the current place of terminal, to notify these base stations to send paging broadcast message or to stop paging.The trigger condition that anchor PC sends the paging declaration is one of following: have the data that need send to terminal to arrive; Network side need force to allow terminal carry out the position renewal; Network side need force terminal to carry out the network reentry; Anchor PC knows that terminal exits from idle mode, and the relevant base station of notice stops paging.
If anchor PC knows the address of each base station in the relevant paging group, then anchor PC directly sends the paging declaration to these base stations; Otherwise, need the paging declaration to be sent to relevant base station, as shown in Figure 4 by relay PC (Relay PC).
After the paging declaration is received in each base station,, then generate beep-page message MOB_PAG-ADV message, its broadcasting is gone out at the paging listening period interval (ListeningInterval) of terminal if this paging declaration is not the order that stops paging.The physical frame of each base station transmission beep-page message in time can be different, as long as within the listening period interval of terminal.In the base station calling time interval (Paging Interval), the base station can send one to repeatedly to the beep-page message of same terminal.All beep-page messages that send in a paging time interval are all as a paging, corresponding paging number of retries (Paging RetryCount) subtracts one, except when the Action of beep-page message Code is set to No Action, promptly when this beep-page message does not have operation, do not change the paging number of retries.When the paging number of retries is kept to zero, the base station stops paging, and think that this terminal can't obtain (unavailable), but the base station does not need to obtain this terminal information reports to PC, if PC never receives the paging success message that the base station reports, think automatically that then this terminal can't obtain.
In the paging, the relation between the Several Parameters as shown in Figure 5.As seen, be the terminal monitoring time interval for some time in each paging cycle among the figure, therefore the base station must can be called the base station calling time interval again at this time period issuing page message.
Terminal exits from idle mode:
If network side has business datum need send to terminal, then can send paging to terminal, after terminal is received paging to it, should in time finish idle pulley, the process that terminal finishes idle pulley as shown in Figure 6:
In step 601, terminal sends distance measurement request (RNG-REQ) message after its Current Serving BTS is synchronous, the request re-accessing network.
Then enter step 602, after the request of accessing terminal to network is received in the base station, to the request of the ASN-GW/PC/DPF of network side transmission to this terminal information, comprising the sign of this terminal, the information that Base Station Identification etc. are necessary.
Then enter step 603, after the ASN-GW/PC/DPF of network side receives this request, generate the end message response, send to relevant base station, wherein comprise terminal information.
Then enter step 604, after response is received in the base station, just send ranging response (RNG-RSP) message, inform the success of terminal reentry network to terminal.
Then enter step 605-607, base station and network side are consulted, for this terminal is set up data channel.
More than terminal entered exit from idle mode, under idle pulley, carry out that the position is upgraded and the process of network side paging terminal of idle mode is illustrated, yet, all increased relay station newly in existing many networks, prior art can not directly apply in the multihop relay system.

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.
Paging is initiated in the base station in this base station range when receiving the beep-page message of idle mode terminals, and transmit this beep-page message to subordinate relay; After subordinate relay is received this beep-page message, in this relay station coverage, initiate paging, and transmit this beep-page message to subordinate relay again, by issuing step by step and paging separately, make in base station and relay station coverage all pagedly, guarantee that this terminal all can successfully receive the beep-page message of network side in any range.
Below first embodiment of the invention is described, present embodiment relates to a kind of paging method, is the paging flow process of base station as shown in Figure 7.
In step 701, the base station is when receiving the beep-page message of terminal of idle mode, and this terminal of paging in this base station range, and this beep-page message is broadcast to its down all relay stations subtracts 1 with the maximum paging number of times of this terminal.Wherein, the base station issues the beep-page message that belongs to this terminal in the paging listening period interval of this terminal, and the base station can issue the one or many beep-page message in this listening period interval.
Because terminal is when receiving the beep-page message of network side, can return page response to the base station that issues this beep-page message or relay station (that is to say in the coverage of this terminal in this base station and then returns page response to the base station, in the relay station coverage, then can return response) to relay station, and, the subordinate relay of base station can be reported to the base station with this page response when receiving the page response of terminal.Wherein, this page response can be the position updating request of terminal, or network reentry request etc.In conjunction with above-mentioned 2 points, in step 702, the page response of base station waits receiving terminal, if before next paging terminal listening period arrives at interval, page response (comprise from terminal and receive or receive from subordinate relay) is received in the base station, then enters step 706, otherwise then enters step 703.
In step 703, the base station judges whether the maximum paging number of times of this terminal is 0, if then enter step 705; Otherwise then enter step 704, the base station subtracts 1 with the maximum paging number of times of terminal, and this next one paging listening period at interval in this terminal of paging, then enter step 702, the page response of wait receiving terminal is continued in the base station.
In step 705, the base station is 0 o'clock at the maximum paging number of times of this terminal, does not still receive the page response of terminal, then stops this terminal of paging, thinks that this terminal can't obtain process ends.Perhaps, consider that relay station reports the required time delay of this beep-page message, can stop this terminal of paging, and continue to wait for a period of time, this section time span can be with the relay station of base station spaced furthest to required transmission time of this base station, the i.e. maximum transmission time of each relay station.If in the period, terminal is not still received the page response of terminal at this section, determine finally that then this terminal can't obtain.
In step 706, the page response of this terminal is received in the base station, this page response is reported PC, stop issuing page message, issue to the subordinate relay of this base station and stop beep-page message, stop to comprise in the beep-page message at this and stop the paging sign, so that determining under the situation of terminal location, each relay station can in time stop paging, reduces unnecessary paging operation, reduces the burden of relay station.Wherein, if this base station directly receives this page response from terminal, then stop beep-page message,, then issue this and stop beep-page message to other subordinate relay except that this subordinate relay if this page response is received from subordinate relay in this base station to all relay stations transmissions of its subordinate.
In addition, in the present embodiment, the base station may receive also and stop beep-page message that the base station need be transmitted this to its subordinate relay and be stopped beep-page message from network side PC.
Be the paging flow process of relay station as shown in Figure 8.
Relay station is when receiving the beep-page message of base station or superordinate relay stations, enter step 801, this terminal of paging in this relay station coverage subtracts 1 with the maximum paging number of times of this terminal, if this relay station is not the final stage relay station, then also this beep-page message is transmitted to its all relay stations down.Wherein, this relay station issues the beep-page message that belongs to this terminal in the paging listening period interval of this terminal, and the base station can issue the one or many beep-page message in this listening period interval.
Then enter step 802, this relay station is waited for the page response of receiving terminal, if before next paging terminal listening period arrives at interval, this relay station is received the page response (comprise from terminal and receive or receive from subordinate relay) of this terminal, then enter step 803, this relay station stops issuing page message, report this page response to superordinate relay stations or base station, and issue to its subordinate relay and to stop beep-page message, stop to comprise in the beep-page message at this and stop paging sign, thereby determining under the situation of terminal location, each relay station and base station can in time stop paging, reduce unnecessary paging operation, reduce the burden of relay station, wherein, if this relay station directly receives this page response from terminal, then stop beep-page message,, then issue this and stop beep-page message to other subordinate relay except that this subordinate relay if this relay station is received this page response from subordinate relay to all relay stations transmissions of its subordinate; If received the beep-page message that stops from base station or superordinate relay stations, then enter step 804, this relay station stops issuing page message, and transmits this to its subordinate relay and stop beep-page message; If both do not received the page response of terminal, do not receive to stop beep-page message yet, then enter step 805.
In step 805, relay station judges whether the maximum paging number of times of this terminal is 0, if then enter step 806, stops this terminal of paging, process ends; Otherwise then enter step 807, relay station subtracts 1 with the maximum paging number of times of terminal, and this next one paging listening period at interval in this terminal of paging, then enter step 802, relay station continues the beep-page message that stops of the page response of wait receiving terminal or base station.
Second execution mode relates to a kind of paging method equally, and is roughly the same with first execution mode, and its difference is, in the first embodiment, when base station or relay station are received beep-page message, immediately it is handed down to subordinate relay; And in the present embodiment, the paging listening period of considering terminal is shorter at interval, and between two paging listening periods intervals arranged the long vacant time, in these vacant times, because terminal is monitoring seek channel not, therefore base station and this terminal of relay station paging during this period of time at this point, are further optimized first execution mode.The basic ideas of optimizing are as follows: if base station or relay station are received beep-page message and can be carried out paging during this period in paging terminal listening period interval, but after this beep-page message sent to subordinate relay, subordinate relay has little time to carry out paging in this paging listening period interval, that is to say, even this base station or relay station are transmitted to subordinate relay with beep-page message, subordinate relay still needs to wait until when next paging listening period arrives at interval and could send beep-page message, therefore, the best way of this base station or relay station is beep-page message not to be transmitted to subordinate relay earlier, whether at first attempt can be before next paging listening period arrives at interval, receive the page response of terminal, if can receive, then do not need to transmit this beep-page message to subordinate again, if can not receive, then again this beep-page message is transmitted to subordinate base station.Thereby avoid issuing unnecessary beep-page message, make subordinate relay carry out unnecessary paging, reduce the burden of subordinate relay.
In addition, in the present embodiment, if this relay station is the final stage relay station, promptly there is not any subordinate relay in this relay station, then need not the forwarding of carrying out corresponding beep-page message and stopping beep-page message.
Fig. 9 shows the paging flow process of base station in the present embodiment.
In step 901, the base station receives the beep-page message from PC.
Then enter step 902, current this beep-page message that whether needs to transmit is immediately judged in the base station, immediately this beep-page message is transmitted to subordinate relay if promptly judgement is current, whether subordinate relay is able to do in time in a current nearest paging listening period this terminal of paging in (as the current paging listening period that is at interval) at interval, and whether subordinate relay needs to wait until could this terminal of paging when next paging listening period arrives at interval.If be able to do in time then current needs are transmitted this beep-page message immediately, enter step 907, otherwise current the needs transmit this beep-page message immediately, enter step 903.
In step 903, this base station at a current nearest paging listening period at interval, this terminal of paging in the coverage of this base station, and the maximum paging number of times of this terminal subtracted 1.Then enter step 905.
In step 905, base station waits is preset duration, and this default duration is smaller or equal to play the time difference of next paging listening period between arriving at interval from this terminal of base station calling.
Then enter step 906, the base station judges whether to receive the page response of terminal, if receive then enter step 914, the base station stops paging, and the page response of receiving is reported PC; Otherwise then enter step 907.
In step 907, the base station is provided with paging number of times in beep-page message, with this paging number of times add 1.
Then enter step 908, the beep-page message after the base station will be provided with is handed down to subordinate relay.
In step 909, the base station judges whether the maximum paging number of times of this terminal is 0, if then enter step 912, otherwise enters step 910.
In step 910, the base station subtracts 1 with the maximum paging number of times of terminal, and this next one paging listening period at interval in this terminal of paging.
Then enter step 911, the page response of base station waits receiving terminal, if before next paging terminal listening period arrives at interval, page response (comprise from terminal and receive or receive from subordinate relay) is received in the base station, then enter step 915, otherwise then enter step 909.
In step 912, continue to wait for a period of time in the base station, this section time span can be with the relay station of base station spaced furthest to required transmission time of this base station, the i.e. maximum transmission time of each relay station.
Then enter step 913, the base station judges in the period, whether to receive the page response of terminal at this section, if receive then enter step 915, otherwise determines that this terminal can't obtain process ends.
In step 915, the base station stops this terminal of paging, and the page response of receiving is reported PC, and generates and to stop beep-page message and send to subordinate relay, and this stops to comprise in the beep-page message and stops the paging sign.Wherein, if this base station directly receives this page response from terminal, then stop beep-page message,, then issue this and stop beep-page message to other relay station except that this subordinate relay if this page response is received from subordinate relay in this base station to all relay stations transmissions of its subordinate.
In addition, stop beep-page message, then stop this terminal of paging, and transmit this to its subordinate relay and stop beep-page message if the base station in said process, receives from higher level PC.
Figure 10 shows the paging flow process of relay station in the present embodiment.
In step 1001, relay station receives the beep-page message from superordinate relay stations or base station.
Then enter step 1002, relay station obtains this terminal paging number of times from beep-page message, according to default maximum paging number of times and the actual maximum paging number of times that should determine this relay station with the paging number of times.The maximum paging number of times of default terminal can be deducted paging number of times, with the actual maximum paging number of times of its difference as this relay station.If not paged before this terminal, then this paging number of times be defaulted as 0, the default maximum paging number of times of relay station this moment i.e. the actual maximum paging number of times that can this terminal of paging of this relay station; Otherwise actual maximum times poor for the maximum paging number of times of default terminal and paging number of times that can call terminal of this relay station.By transmitting paging number of times, make the paging number of times of terminal reality can be controlled in the preset range, avoid actual paging number of times to surpass default maximum paging number of times, make the base station wait as long for the response of terminal.
Step 1003-step 1015 is similar with step 902-step 914, its difference only is, application entity in the step 902-step 914 is the base station, the base station is when receiving page response, page response is reported PC, and the application entity in the step 1003-step 1015 is a relay station, and relay station is when receiving page response, with the page response reporting base station.
In step 1016, relay station is received the page response of terminal, this relay station stops issuing page message, report this page response to superordinate relay stations or base station, and issue to its subordinate relay and to stop beep-page message, stop to comprise in the beep-page message at this and stop the paging sign, thereby determining under the situation of terminal location, each relay station and base station can in time stop paging, reduce unnecessary paging operation, reduce the burden of relay station.Wherein, if this relay station directly receives this page response from terminal, then stop beep-page message,, then issue this and stop beep-page message to other relay station except that this subordinate relay if this page response is received from subordinate relay in this base station to all relay stations transmissions of its subordinate.
In addition, in this flow process, receive at relay station before the page response of terminal, if from the base station or superordinate relay stations receive and stop beep-page message, then stop this terminal of paging, and transmit this to its subordinate relay and stop beep-page message.
In first and second execution modes, transmit beep-page message, stop beep-page message in order to support base station and relay station, and paging number of times is set in beep-page message, need make amendment to former beep-page message, amended beep-page message form is as shown in table 1.6 reservation bits in the former message are revised as 3 reservation bits, utilize 1 bit wherein to identify simultaneously as stopping paging, indicate whether to stop paging, the number of times of paging with 2 bit indicating terminals, make base station and subordinate relay send the gating message times sum and can not surpass default maximum paging number of times, thereby controlled the time of base station waits paging terminal response better.Dash area is the change to the MOB_PAG-ADV message corresponding field that defines in the IEEE802.16e agreement in the table 1.
Beep-page message form (MOB_PAG-ADV):
