Abstract

A radio access network (104) provides for an ordered registration of a mobile station (MS) (102). A downstream entity (118, 132) conveys a message (202) to a base station (BS) (106) requesting that the MS be instructed to register. The BS then transmits a message (208) to the MS that instructs the MS to register. In response to receiving the registration instruction, the MS transmits a registration message (210) to the BS. Upon receiving a registration message, the BS conveys a message (212) to the downstream entity requesting an update of a location of the MS. The downstream network entity updates the MS's location and conveys a message (218) to the BS confirming an updating of the location of the MS. In another embodiment of the present invention, the MS can initiate a user-zone based registration by conveying a user-zone based registration message to the BS.

In another embodiment of the present invention, registration message can comprise the difference time of advent of the signal signal that is used for three base station, that determined by MS, and further comprises the identifier of each base station.Then, RAN can be according to the difference of determining and determine the position of MS with reference to the database (not shown) that is stored in position among the RAN, that comprise each base station among the RAN time of advent.

When receiving registration message, BS 106 sends to position updating request in (212) descending device through A1 interface 126, this descending device is initiated registration process and is MS 132, and enable position renewal timer (214), and this timer preferably is included in the timer 113 in the BS.Position updating request is notified the MS of initiations (sourcing) request according to the position that provided by MS in registration message be the position of MS 102, and request MSC 132 upgrades the position that the position one-tenth of MS 102 provides in registration message.Position updating request notifies further whether registration is Ordered Registration, and promptly whether Zhu Ce MS registers according to the indication that receives from RAN 104.Position updating request can further comprise the user area log-on message, and it points out when MS is in activation rather than idle condition whether initiate registration by the MS that wants to register in the user area that MS selects.

Preferably, the position updating request of exchange is Direct Transfer Application Part (DTAP) message between BS 106 and MSC 132, especially, this message is the location update request message in TIA/EIA IS-2001-/A.S0001-A standard, unless revise message to provide Ordered Registration and based on the log-on message of user area according to embodiments of the invention.Referring now to Fig. 4 a and 4b,, the bitmap layout of part has illustrated the location update request message of revising 400.Location update request message 400 comprises: first group of data, and preferably the type of message indicator data field 402, and it informs that this is a location update request message; Second group of data, preferably mobile logo symbol data field 404 is unique relevant with registration MS (being MS 102), and discerns it; The 3rd group of data, preferably class label information data field 406 is discerned the attribute of MS, and notifies the wave band classification capacity of the MS of registration; With the 4th group of data, preferably registration type data field 408, the registration type that regulation MS carries out.Registration type data field 408 comprises: first data subset, and " order " data field 410 preferably, whether its notice registration is Ordered Registration, wherein the MS of registration registers according to the indication that receives from RAN 104; With second data subset, preferably " based on the user area " data field 412 is pointed out when MS is in activation rather than idle condition, by the registration of the MS initiation of wanting to register in the user area that MS selects.Change to this message is new " order " and " based on the user area " registration type.T _OrdregIt is the new timer that we stipulate.This should be understood that? this is unclear from literal.

When MSC 132 at the first predetermined period of time T that sends register requirement from MSC _OrdregBefore surpassing during the receiving position update request, MSC stops (206) timer 136, the position of MS102 in the location database 134 is provided according to the position that provides in position updating request, and send (218) position through A1 interface 126 and update confirmation message to base station 106, the MS of this message authentication registration is that the position of MS 102 is updated.Preferably, the position upgrade acknowledge message be confirm successfully to handle position updating request and the position of the position of the MS 102 of updated stored upgrade and accept message.It is known in the art that message is accepted in the position renewal, in the IS-2001-A/A.S0001-A standard introduction is arranged.T _OrdregDetermine with reference to timer 136 by MSC 132, and scope is 1 to 99 second.Preferably, if MS 102 works T in slotted mode _OrdregContinue 4.72+1.28*2 ^{Slot Cycle Index}Second, if MS 102 does not work in slotted mode, then be 10 seconds.

When MSC 132 in the preset time period T _OrdegDo not receive position updating request before surpassing, the register requirement process can finish or MSC can restart registration process 200 to BS 106 by retransmitting register requirement.In the situation of back, when MSC 132 trial pre-determined numbers did not receive position updating request with Ordered Registration MS 102 in first predetermined period of time, then flow process finished.Yet, in another embodiment of the present invention, when MSC 132 trial pre-determined numbers receive position updating request with Ordered Registration MS 102 in first predetermined period of time, MSC can send a request for registration to different BS, as BS 138, and/or the extra cell in current BS 106, and repeat the ordered registration process 200 of different relatively BS and/or extra cell.

When BS 106 at the second predetermined period of time T that sends position updating request from BS ₃₂₁₀When receiving renewal acknowledge message in position before surpassing, BS 106 stops (216) position renewing timer 113, and the registration confirmation message that will confirm to accept the registration message of MS 102 by RAN104 and upgrade the position of MS through Forward Common Signaling Channel (f-csch) 154 sends to (220) MS 102.Preferably, registration confirmation message is to register the message that takes orders, and this message is known in the art, in the 3.7.4.5 of EIA/TIA IS-2001-A-1 standard part introduction is arranged.It is that timer 113 determines whether second predetermined period of time surpasses that BS 106 upgrades timer by reference position.Yet, in another embodiment of the present invention, do not send registration confirmation message.

When BS 106 at the second predetermined period of time T ₃₂₁₀When not receiving renewal acknowledge message in position before surpassing, BS can resend the location update request to MSC 132, and the enable position of laying equal stress on is upgraded timer 113.When BS 106 trial pre-determined numbers do not have response not receive position renewal acknowledge message in second predetermined period of time to send position updating request to MSC136, then flow process end.

In another embodiment of the present invention, the downlink network device of initiation registration MS 102 can be PCF 118 rather than MSC 132.That is, the function that relative MSC 132 introduced above PCF 118 can carry out is communicated by letter with BS 106 except PCF 118 uses A9 interfaces 116 rather than A1 interface.Yet, persons of ordinary skill in the art will recognize that the downlink network device of BS (that is, the BS 106) communication of any and service MS 102 can initiate to register MS 102, and need not to deviate from the spirit and scope of the present invention.That is, return Fig. 2, but replace MSC 132 and A1 interface 126 with PCF 118 and A9 interface 116, PCF 118 initiates ordered registration process by sending (202) register requirement to BS 106.Preferably, register requirement is sent to the A9-login request message of BS 106 through A9 interface 116 by PCF118.Yet in another embodiment of the present invention, register requirement can comprise the revision of the current message that exchanges between PCF 118 and BS 106, and such as the A9-paging request message, it is modified and comprises that a data field is to point out to require the mobile radio station registration.The composition of A9-login request message is similar to the composition of A1-login request message, except 302 these message of identification of the type of message data field in the login request message are passed through the A9 interface (promptly as quilt, A9 interface 116) rather than the A9 interface message that transmits of A1 interface, and this message is not BSMAP message, therefore, the message of transmission does not have the SCCP head that appends on it.When PCF 118 sent the A9-login request message, PCF also started registration timer, preferably started the timer 119 that is included in the PCF.

Similar with MSC 132, PCF 118 responds then and transmits register requirement, wait through A9 interface 116 from BS 106 receiving position update requests, (it is the revision of the A1-location update request message 400 of modification preferably to receive the A9-location update request message, but not DTAP message, and do not have the SCCP head that appends on it).When PCF 118 is sending the first predetermined period of time T that register requirement begins from PCF _OrdregBefore surpassing during the receiving position update request, PCF stops (206) timer 119, update stored in the position of the MS 102 in the location database 134, and send (218) positions through A9 interface 116 and upgrade acknowledge messages (preferably the A9-position is upgraded and accepted message) to the base station 106.Preferably, in this embodiment of the present invention, wherein PCF 118 is as descending device, and location database 134 is arranged in the RAN 104 of MSC 132 outsides, and is operably connected to PCF 118.The BS (that is, BS 106) that initiates to upgrade acknowledge message in the position is by 116 identifications of A9 interface, and described message is received through A9 interface 116.

When PCF 118 in the preset time period T _OrdegDo not receive position updating request before surpassing, the register requirement process can finish or PCF can restart registration process 200 to BS 106 by retransmitting register requirement.When PCF 118 trial pre-determined numbers received the position updating request of response with Ordered Registration MS 102 in first predetermined period of time, flow process can finish.Yet, in another embodiment of the present invention, when PCF trial predetermined times receives position updating request with Ordered Registration MS 102 in first predetermined period of time, PCF can send a request for registration to different BS, require to send the extra cell of log-in command such as BS 138 and/or regulation, and repeat the ordered registration process 200 of different relatively BS.

By providing the register requirement that is sent by the downlink network device such as MSC 132 or PCF 118 to the uplink network device such as BS 106, promptly with MS (that is, MS 102) communication, communication system 100 can be initiated Ordered Registration MS.Device indication of " register requirement " request uplink network or order MS register.The uplink network device be BS 106 when receiving register requirement, the log-in command that instruct MS is registered is to MS 102.Response receives log-in command, and MS 102 registers to BS 106 by sending registration message, and this BS sends position updating request again then to originating MS C 132 or PCF 118.When receiving position updating request, originating MS C 132 or PCF 118 are updated in the position of the MS 102 in the location database 134, and delivering position updates confirmation message to BS 106.Then, BS 106 can send registration confirmation message to the MS 102 that confirms registration.

When first predetermined period of time surpassed after MSC 132 or PCF 118 send a request for registration to BS 106 and before MSC or PCF receive the response position update request, MSC or PCF can come the repeated registration process to BS 106 by retransmitting register requirement.In addition, when BS 106 sent position updating request second predetermined period of time surpasses after MSC 132 or the PCF 118 and before acknowledge message is upgraded in the position that BS receives response, BS can resend the location update request to MSC or PCF.By the ordered registration process that provides network to initiate, communication system 100 can provide to force and move war and register to network, and what (and if any) be no matter mobile radio station is compiled to the registration type carried out.The situation of desirable this example comprises: only allow based in the zone of the registration in zone more between efficient system Short Message Service (SMS) send, write down when deleted when regularly exceeding VLR, when requiring to upgrade the position of MS immediately, perhaps register automatically with after reducing common channel traffic at system closing.

In an alternative embodiment of the invention, not that RAN 104 initiates the MS102 that registration activates, registration in this zone, is wished to register and initiate in the user area of MS selecting activation in the user area that is in selection activation rather than idle condition.The user area is the subregion of the geographic area of RAN 104 services, and comprises by the one or more coverages of serving that are included in a plurality of base stations 106,138 among the RAN.The notion of user area is known, and at length introduces at the 2.6.9.1.1 of IS-2000 standard and the part of 2.6.9.1.2.When MS 102 wish be in activate rather than the user area of the selection of idle condition in when registering, MS 106 initiates to register to the base station by sending registration message, as top with reference to the step 210 of call flow Figure 200.Point out registration from the registration message of MS based on the user area.

When BS receives registration message, BS arrives MSC 132 through A1 interface 126 delivering position update requests (preferably location update request message 400), perhaps be sent to PCF 118 through A9 interface 116, introduction as the step 212 of top call flow block diagram 200, and enable position renewal timer promptly is included in the timer 113 among the BS, as the introduction in the top step 214.BS can point out that this registration is based on the registration of user area through the son field 412 of " based on the user area " of location update request message 400, described data field comprises information, and this information points out that the MS that registers by wanting to register initiates in the user area that MS selects when being in activation rather than idle condition.Location update request message 400 is further upgraded the position of MS 102 through 402 requests of type of message data field.

When MSC 132 or PCF 118 receiving position update requests, MSC or PCF update stored in the position of the MS 102 in the location database 134, and update confirmation message to BS 106 through separately A1 interface 126 or A9 interface 116 transmission positions, as the step 218 of the call flow Figure 200 that introduces above.When BS 106 at the predetermined period of time T that sends position updating request from BS ₃₂₁₀When receiving renewal acknowledge message in position before surpassing, BS106 stops timer position renewing timer 113, and send registration confirmation message to MS 102 through Forward Common Signaling Channel 154, the same as the step 216 of the call flow Figure 200 that introduces above with 220.BS 106 upgrades timer 113 by reference position and determines period of time T ₃₂₁₀Whether surpass.In another embodiment of the present invention, do not send accreditation verification.

When at the second predetermined period of time T ₃₂₁₀When BS 106 did not receive position renewal acknowledge message before surpassing, BS retransmitted and send position updating request to arrive MSC 132 or PCF 118, and restarts position renewing timer 113.Attempt pre-determined numbers to send position updating request at BS 106 to MSC 136 or PCF 118 and not in the preset time period T ₃₂₁₀In receive response position when upgrading acknowledge message, flow process finishes.If based on succeeding in registration of user area, then MSC 132 or PCF 118 and/or BS 106 offer the specific feature of MS according to the active user zone of MS.By the registration that allows MS 102 to initiate based on the user area, communication system 100 allows MS to select the user area of activating.

Although with reference to particular specific embodiment the present invention is illustrated and illustrates, those skilled in the art will understand, and under the conditions without departing from the spirit and scope of the present invention, can carry out various changes, and parts are wherein carried out the equivalence replacement.In addition, under the condition that does not deviate from essential scope of the present invention, can carry out the situation that various modifications adapt to specific situation or the present invention's instruction.Therefore, hope the invention is not restricted to the specific embodiment in this introduction, but the present invention will comprise all embodiment that drop in the scope of pointing out in the claim.
