Abstract
Methods and systems for handling errors associated with pre-paging in radiocommunication networks are described. If radio contact to a terminal is lost after a successful pre-page, the network can detect this event. Then, when the corresponding call delivery message is received, the network can re-page the terminal and re-allocate radio resources if the terminal is available. Additionally, a guard timer can be started when radio resources are first allocated. If the call delivery message is not received prior to expiration of the timer, the radio resources can be deallocated to avoid wasting such resources in the event that the call delivery message is lost in the network.
Description
Relevant/priority application
The application requires on May 10th, 1999 to submit to, is entitled as the priority of the U.S. Provisional Patent Application 60/133688 of " gateway location register and pre-paging in the global mobile communication system ", is incorporated herein its content as a reference.
Background of invention
The present invention relates to the paging technique in the wireless communication system, and specially refer to the technology of handling the mistake in the wireless system that adopts pre-paging more.
In other area in the U.S. and the world, wireless communication industry has obtained development at full speed in the commercial operation field.Growth in main metropolitan area is well beyond people's expectation, and breaking through its power system capacity apace.If this trend sustainable development, this industry increases effect of being brought even the market that can feed through to smallest size.For satisfying these ever-increasing capacity requirements, can keep higher quality of service again simultaneously, and avoid raising the cost, then need to propose the solution of novelty.
In this wireless communication system a kind of technology of usually adopting be considered to paging.Paging a kind of process that comes to this, promptly wireless communication system positions (for example call ending trial, message transmission etc.) to the terminal of signal post's request.For example in many wireless communication systems, an idle mobile stations (travelling carriage that does not promptly have the distribution service channel) is wanted monitoring seek channel, searches for the beep-page message that those have its institute's addresses distributed.This snoop procedure can be periodic, makes terminal reduce the power of battery between can be during monitoring, and saves battery power consumption.Yet when terminal received a paging that possesses its addresses distributed, terminal can be confirmed paging, and beginning connects between terminal and wireless communication system.Comprise the routing iinformation that paged terminal is provided to wireless communication system in this process, make message suitably to be sent on the current location of terminal.
At the gsm wireless communication system conventional paging technique example is described now.Except other guide, in the normative document that is called as GSM TS 09.02 (ESTI ETS 300 974), at least also the paging technique that is used for gsm system to have been described partly, its content is hereby incorporated by.Wherein concerning the GSM network, in the time will connecting with terminal, MAP (MAP) is given for the conventional process of handling the Signalling exchange between visit PLMN (VPLMN) and the Home PLMN (HPLMN).
This conventional process that connects with terminal 5 has been described among Figure 1A.Wherein, GMSC (gateway mobile switching center) (GMSC) 10 receives the initial address message (IAM) (message 1) of a calling that will be passed to specific mobile subscriber of being used to terminate.Then, GMSC 10 is to the roaming sequence number of ownership location register (HLR) 20 requesting terminals 5.Can make GMSC 10 can MSC (drawing) do not carried out addressing like this, current support of this MSC and the radio communication that is in the terminal 5 in the VPLMN.GMSC 10 transmits one by the HLR 20 to HPLMN and sends routing iinformation (SRI) message (message 2), finishes this operation, and wherein, this HPLMN " has " user (promptly this HPLMN be the Home System of this terminal) relevant with terminal 5.It should be noted that in Figure 1A just from the conceptive physical relation that has provided between the node; Its physical implementation can change.For example, GMSC can be contained in HPLMN or the PLMN that starts in.
When HLR 20 received SRI message from GMSC 10 (this GSMC needn't be in the HPLMN), HLR 20 can roam sequence numbers to the visited mobile switching center that service is provided for terminal 5 zones of living in/visit location register (VMSC/VLR) 30 requests.Can be taken as separate nodes although it should be noted that VMSC and VLR when implementing, in this example, they are illustrated as a combined joint.And in whole description process, need relate to this two nodes individually.The request of roaming sequence number can be finished in the following way, for example: send one to VMSC/VLR 30 roaming sequence number (PRN) message (message 3) is provided.VMSC/VLR 30 in the VPLMN provides the roaming sequence number, utilizes PRN and SRI message that this roaming sequence number is sent to GMSC 10 through HLR 20 then again.GMSC 10 can transmit IAM (message 4) to VMSC/VLR30 then.
In a single day VMSC/VLR 30 has received IAM (message 4), will a plurality of inside stories (the transmission information that promptly is used for incoming call, paging) occur at the VMSC/VLR intranodal, and as its result, and user terminal can paged (message 5).Confirm according to the paging that receives from terminal, can between serving BS (not providing) and terminal, set up Traffic Channel, thereby go to connect.Figure 1B is the flow chart that is used for representing the process that described above and Figure 1A indicates.The key character of conventional paging technique is exactly: as shown in these figures, receive IAM message up to VMSC/VLR, just can carry out paging to terminal 5.
Recently there has been the internuncial scheme of another processing terminal to be considered, this scheme can be known as paging or pre-paging before the route.In the wireless communication system that adopts pre-paging, when VMSC/VLR receives roaming sequence number (for example MSRN) when request from HLR, VMSC/VLR just can start to the paging of user terminal, rather than waits for resembling in the above-mentioned conventional paging technique, is transmitted up to IAM.And, just can send the roaming sequence number to HLR up to receiving a current available page response of the indicating terminal from user terminal, this also is different from above-mentioned technology (wherein VMSC/VLR returns the roaming sequence number immediately according to the request of HLR).
Compare with the conventional paging technique among Figure 1B with Figure 1A, this pre-paging process possesses a significant advantage at least.If user terminal is not made response to paging; make and to finish calling (this situation occurs through regular meeting); needn't reserve exchange and transfer resource this moment between GMSC 10 and VMSC/VLR 30, and need this is kept in above-mentioned conventional GSM process.Therefore the pre-paging technology can be saved exchange and the transfer resource in target and the transition network.
Described among Fig. 2 A and be used to handle the relevant conventional process of internuncial demonstration pre-paging technology.As shown in FIG., GMSC 10 receives the initial address message (IAM) (message 1) of a calling that will be passed to portable terminal 5 of being used to terminate.GMSC 10 asks to roam sequence number (message 2) by sending SRI to HLR then.HLR comes to VLR request roaming sequence number by sending PRN (message 3).
Arrive this, GSM process illustrated among the process that illustrates among Fig. 2 A and Figure 1A and the 1B is identical.Yet the VMSC/VLR 30 in VPLMN provides before the roaming sequence number, VMSC/VLR30 need carry out pre-paging (promptly to terminal 5, even VMSC/VLR does not also have IAM message, also can carry out paging to terminal), to guarantee the user availability (message 4) in its coverage.Only after successfully the user being carried out pre-paging, VMSC/VLR 30 just can provide the roaming sequence number, and (promptly by PRN and SRI response) is delivered to GMSC 10 to this sequence number through HLR 20.And only after successfully the user being carried out pre-paging, could be desired call distribution Radio Resource, for example, in response to the paging request, can be for portable terminal distribute a signaling channel, and selectively, distribute a Traffic Channel that can connect calling thereon.After the response that receives SRI message, GMSC 10 can pass to VMSC/VLR 30 to IAM (message 5).The information flow chart that Fig. 2 B explanation is relevant with the process of Fig. 2 A.
Pre-paging function under the process reflection normal condition that illustrates among Fig. 2 A and the 2B, promptly the all-network node that is comprised in the process can normally be worked.Yet the situation that also can occur network failure in the pre-paging process, this inefficacy meeting brings negative influence for the performance of wireless communication system.For example consider following situation: after paged and VMSC/VLR 30 also provides the roaming sequence number when terminal 5, lost and user terminal 5 between radio contact.When IAM message is arrived soon after VMSC/VLR 30, owing to Radio Resource is released, so VMSC can not connect IAM message and described terminal.
As the another one example that network failure in the middle of the pre-paging process, can occur, consider this situation: wherein paged the and VMSC/VLR 30 of terminal 5 also provides after the roaming sequence number, because network is congested, the IAM message that makes GMSC 10 send is being lost from the routing procedure of GMSC 10 to VMSC/VLR 30.In this case,, also still can be desired call distribution Radio Resource, keep that therefore this situation can cause lower power system capacity owing to non-essential resource occurs even in network, lost IAM message (and therefore can not set up calling).
Correspondingly, hope provides such pre-paging technology in wireless communication system, it can keep the benefit of conventional pre-paging technology (for example when terminal is unavailable, avoid using Internet resources to go to transmit IAM message), and can also handle simultaneously the fault and the erroneous condition of these types in the network.
Summary of the invention
According to example embodiment of the present invention, the applicant has developed the wrong program that solves, to avoid taking place the problem that the user in the VPMLMN may be occurred by pre-paging afterwards.
For example according to first example embodiment of the present invention, can solve after pre-paging user terminal and wireless between get in touch the problem of losing.According to this example embodiment, system monitoring to and notice losing of radio contact.According to the call-delivery message that receives, if feasible, can carry out paging once more to terminal, and distributing radio resource for it once more.Like this, second group of Radio Resource is relevant with the call origination message that receives, and sets up and call out.
According to another example embodiment of the present invention, can solve the problem that after paging, when waiting for the IAM message of having lost, continues to keep Radio Resource.According to this example embodiment,, after distributing radio resource, need to start the protection timer in order to respond successful pre-paging.If described protection timer expiry before receiving call origination message then discharges institute's assigned radio resource.

Detailed Description Of The Invention
For complete understanding of the present invention is provided, in description subsequently, provided specific detail, for example particular electrical circuit, circuit unit, technology or the like, but this all is for purposes of illustration, rather than for the purpose of restriction.Yet to one skilled in the art, the present invention can be implemented in the middle of other embodiment that breaks away from these specific detail clearly.In other cases, obscure for the description of this invention not causes, the detailed description of those known methods, equipment and circuit all has been omitted.
Be described to implement in this exemplary wireless communications systems of discussing, wherein go to implement communicating by letter between base station and the portable terminal by a plurality of time slots according to the GSM standard that adopts time division multiple access (TDMA) agreement.Yet it will be appreciated by those skilled in the art that, notion set forth herein also can be applied in the system according to other agreement operation, comprising (but being not limited to) frequency division multiple access (FDMA) and code division multiple access (CDMA), the perhaps combination in any of other above-mentioned agreement.
For this paper, Fig. 3 is provided as the universal instance that wherein can implement conventional cellular radio Communication system 100 of the present invention.Comprise a plurality of wireless base stations (BS) 30a-30n that communicates with a plurality of portable terminals in the wireless communication system 100, wherein only provided a travelling carriage (MS) 5.Downlink communication typically is used as in 5 communication from base station 30a to travelling carriage, and the communication from the portable terminal to the base station is taken as uplink communication.
According to the present invention, when utilizing the pre-paging technology between wireless communication system (representing by base station 30a among Fig. 3) and travelling carriage 5, to connect, can solve above-mentioned various potential erroneous condition.At first, example embodiment of the present invention can solve and successfully lose relevant problem (shown in Figure 4 and 5) with the user terminal radio contact after the pre-paging.At first, utilize for example above-mentioned IAM, SIR and PRN signal to remove originating call in step 500.In this article, call out to start and just be meant call-delivery or set up a calling that in cell phone for example, terminates.Carry out pre-paging in step 502 pair terminal then.As mentioned above,, for example distribute a signaling channel, can wait for that by this channel call transmission sets up information (for example channel assignment message) in case travelling carriage 5 by pre-paging, distributes first group of Radio Resource for it in step 504.If MSC/VLR 30 receives IAM message, and travelling carriage utilizes first group of Radio Resource and system to carry out wireless connections ( step 506 and 508 simultaneously, respectively according to "No" and "Yes" two paths), then can utilize those resources to set up and call out (step 510).
Perhaps, if for example travelling carriage shifts out the scope (this base station has been assigned with by the signaling channel that distributes and has sent the call setup information to travelling carriage 5) of base station 30a during pre-paging, then travelling carriage 5 can not use first group of resource to go monitoring system.
In case radio contact is lost, MSC/VLR 50 can notice this incident (for example by a sign relevant with mobile station identification number is set in step 512), and divides all Radio Resources that are used in call setup before step 514 discharges.In Fig. 4, add heavy line by the black that extends vertically downward from the pre-paging square that connects travelling carriage 5 and MSC/VLR and be connected the release of representing this resource.When last time, paged user-dependent IAM message arrived MSC/VLR (step 516), MSC/VLR just can notice and IAM message in the wireless connections of being set up between the terminal that identified lose the state of the flag bit of setting in the memory (for example by).Carry out the paging second time at step 518 pair travelling carriage 5 then, to guarantee the availability of this terminal in the MSC/VLR coverage.If the user is still available, then distribute second group of resource (can be identical or different) with support call, and MSC/VLR makes input IAM message be associated with the Radio Resource of late allocation, thereby finish call establishment with first group of Radio Resource.
Another problem relevant with conventional pre-paging technology (promptly how to handle after the pre-paging, IAM message loses in the network) can be resolved by the example embodiment of the present invention of explanation in Fig. 6 and 7.This problem is described in front to some extent, but in the flow chart of Fig. 5, by the circulation that the "No" path of noting outside the decision block 508 and 516 is generated, also can easily see this point.According to above-mentioned, system's originating call (step 700), and pre-paging terminal (step 702).In case carried out successful pre-paging, then in step 704, MSC/VLR distributing radio resource (for example signaling channel, and possible Traffic Channel).Start the protection timer in step 706 then.This protection timer possesses inverse (or positive number) time, this time should receive the indication of pre-paging success with GMSC and the IAM message that finally obtains to arrive the total time length that MSC/VLR experienced relevant.For example, although it will be appreciated by those skilled in the art that, specific guard time length can change, and this time span can be the order of magnitude of 20ms.
In case started the protection timer, MSC/VLR 30 can inquiry to the reception (shown in step 708) of IAM message, this message is relevant with the terminal with assigned radio resource on pre-paging basis successfully.If receive this message, MSC/VLR can set up calling (shown in step 710).Protected timer expiry (from the "Yes" path of decision block 712s) else if before receiving IAM message, then MSC/VLR discharges the resource that is assigned with in step 714.When network failure as implied above occurring, start the protection timer in the VMSC, to guarantee that discharging Radio Resource in time can provide multiple benefit.Even for example failure conditions occurs in during the pre-paging, adopt the UMTS network of pre-paging function also can provide powerful capacity.
From all angles, above-mentioned example embodiment all is for the present invention is described, rather than restriction the present invention.Like this, the present invention can produce various variations in implementing in detail, derives these embodiments in those skilled in the art's description that from then on place comprises.For example, the embodiment among Fig. 5 and Fig. 7 just can be combined in together at an easy rate.These all variations and revise all considered to be in subsequently in the claim within the defined scope and spirit essence of the present invention.
