Different from the legacy system that wherein user equipment (UE) 100 is interacted with wireless access point 110, recent system allows UE 100 is interacted with one or more wireless access point 110 and 115.As described above, Fig. 1, which is shown, is connected to two of UE 100 Wireless access point 110 and 115.However, the disclosure is not limited to the embodiment of Fig. 1, and obviously, UE 100 may not be always with two A interaction of wireless access point 110 and 115.

In the whole text unless otherwise stated, this instruction is general wireless if referring to an access point 110 in specification Access point；And if referring to two wireless access point 110 and 115 together, this first wireless access point of instruction is UE 100 The wireless access point 110 mainly interacted, and the second wireless access point is the secondary wireless access interacted of UE 100 Point 115.If the quantity for the wireless access point that UE 100 is connected to is 3 or more, interacted with 100 strategic points UE The quantity of wireless access point can be one or more.

In above-mentioned network structure, following point be may occur in which.One problem is since certain reason fails registration location UE 100 will be spent for a long time for the location register that again attempts to of respective wireless access point 110, and another problem is that when with When the connection status of UE mainly interactive wireless access point 110 deteriorates, the wireless access point 115 that is interacted with UE strategic point with it Connection status be not considered, so as to cause the wasting of resources.Problematic situation is explained in more detail.

Fig. 2 is the diagram for illustrating the situation according to an embodiment of the present disclosure for causing first problem.

Referring to Fig. 2, UE 100 can utilize the service from mobile communication system to be registered and/or from mobile communication system Service is received, the mobile communication system is using different wireless access technologys (RAT) and/or has different RAN controlled entity groups The different RAN controlled entities group of group identifier operates.UE can be at idle state.

If as reference number 210 indicate UE 100 from another RAT or another RAN controlled entity group mobility, Such as being moved to region 300 from region 200, then UE 100 sends tracking area update (TAU) request to RAN controlled entity 130 Message.Alternatively, if as reference number 215 occurs being sent to network at UE 100 and/or receives from network representedly Any data, then UE to RAN controlled entity 130 send service request information.RAN controlled entity 130 is sent to from UE 100 Message relayed by wireless access point 110.

If gone wrong when receiving TAU request message or service request information from UE 100, RAN controlled entity 130 can send the message of the request message of refusal UE 100 to UE 100, that is, TAU refuse information or Service Reject message. The information for the reason of RAN controlled entity 130 can include description in refuse information and/or imply problem.Refuse information is by from RAN Controlled entity 130 is sent to UE 100 via wireless access point 110.

If UE 100 can be such as reference number 240 receives refuse information from RAN controlled entity 130 representedly It includes that request is enclosed in new the reason of carrying in refuse information that reference number 280, which representedly is sent to RAN controlled entity 130, Message.The example of reason may include that RAN controlled entity 130 fails the case where obtaining the identifier of UE 100, and UE 100 is by the dark Separated situation, and the case where basic un-activation carrying information.These three reasons in evolved packet system (EPS) respectively with Cause value 9,10 and 40 matches.

After sending refuse information to UE 100, RAN controlled entity 130 can be ordered as represented by reference number 250 Wireless access point 110 discharges the context about UE 100.UE context release command message can be used to transmit for this order.

If receiving release command from RAN controlled entity 130, wireless access point 110 can send to UE 100 and request The message of Connection Release.The example for being sent to the connection release message of UE 100 from wireless access point 110 includes RRCConnectionRelease message.

If as reference number 260 reaches simultaneously from the release message that wireless access point 110 is sent to UE 100 representedly And the time such as reference number 280 represented ground UE 100 that the wireless connection for therefore arriving network is completely released is controlled to RAN Entity 130 sends the new time for enclosing request message earlier, then UE 100 can there is no problem ground execute this enclose process.

Otherwise, if as reference number 260 be sent to representedly from wireless access point 110 release message of UE 100 to It reaches and therefore arrives time such as reference number 280 represented ground UE 100 that the wireless connection of network is completely released to RAN Controlled entity 130 sends that the new time for enclosing request message is slower, then problem may occur in which.That is, this situation indicates UE 100 Request message is enclosed to the transmission of RAN controlled entity 130, is then wirelessly connected and is released.To which UE 100, which regards this as, to be enclosed Problematic situation in journey and wait the relatively long time (such as 10 seconds) to again attempt to location register.When waiting long Between when, UE 100 cannot receive service and therefore user by inconvenience.

Description is by for solving the problems, such as that embodiment of the disclosure described in reference diagram 2 forms.However, to solve the problems, such as It is not limited to situation as shown in Figure 2, but including obviously increasing since certain reason not can be carried out the UE benefit of location register The all scenario of the time needed for respective wireless access point again execution position registration.

In order to solve problem above, two different embodiments are contacted to describe the disclosure.However, for art technology For personnel, it is clear that the various embodiments for the technical concept that the disclosure is hereinafter realized being described can be carried out it is all can Modification.

Referring to Fig. 2, embodiment of the disclosure have the property that its make as represented by reference number 260 from wireless The arrival time that access point is sent to the release message of UE 100, prior to as represented by reference data 280 UE 100 was controlled to RAN Entity 130 processed sends the new time for enclosing request message.

Another embodiment of the present disclosure has the property that it avoids the connection between UE 100 and wireless access point 110 It is released, i.e. cancellation operation as represented by the reference number 260 in Fig. 2.According to the present embodiment, release message is not by from wireless Access point 110 is sent to UE 100.

Difference between the different embodiment of two above is whether to reuse wireless connection.That is, previous embodiment The characteristics of be to discharge the connection between UE 100 and wireless access point 110 at all costs for new position at UE 100 Set registration.The characteristics of latter embodiment, is to reuse the wireless connection previously established without discharging UE 100 and wireless access Connection between point 110, so as to the location register that please be look for novelty.

The two different embodiments all can be avoided due to being sent to releasing for UE 100 from wireless access point 110 The time for putting the arrival of message and discharging wireless connection sends new position register request to RAN controlled entity 130 in UE 100 Time after, to avoid UE from waiting long to request location register again, lead to the reduction of delay time.

Fig. 3 is the signal flow diagram of the signal stream between diagram UE according to an embodiment of the present disclosure and network, and more in detail Carefully, show RAN controlled entity to wireless access point send instruction terminal new location register necessity indicator And the operation of RAN controlled entity or wireless access point to one of the UE timer sent.

Referring to Fig. 3, UE 100 and wireless access point 110 may know that the situation for needing new location registration.UE 100 Either wireless access point 110 can be sent based on timer triggers new location registration or is wirelessly connected disappearing for release process Breath.

RAN controlled entity 130 can determine the new position of UE 100 in the case of specific problematic in operation 310 The necessity of registration.As described above, problematic situation can be with the cause value 9,10 and 40 used in EPS at least One corresponding situation.RAN controlled entity 130 the determination that operation 310 is made can have UE 100 location register or The property of service request.

RAN controlled entity 130 can be to the new location register of 110 transmission timer of wireless access point and notice UE 100 At least one of indicator of necessity.The information for being sent to wireless access point 110 from RAN controlled entity 130 can be in downlink It is carried in link NAS conveying message.Downlink NAS conveying message be used to convey UE 100 and RAN controlled entity 130 it Between Non-Access Stratum (Non-Access Stratum, NAS) message.The NAS message carried in downlink NAS conveying message Example include TAU refusal and service-denial.The information for being sent to wireless access point 110 from RAN controlled entity 130, which can be used, to be used The UE context release command message of connection is discharged in order UE 100 to send.

Notify the indicator of the necessity of the new location register of UE 100 that can express in many ways.For example, indicator It can be using the reasons why simple binary message or the new location register necessity situation of UE or cause value is expressed.

Wireless access point 110 can operate 330 to UE transmission timer.Timer can be included in In the NAS message carried in DLInformationTransfer message or DLInformationTransfer message.

From RAN controlled entity 130 it is sent to the timer of wireless access point 110 in operation 320 and from wireless access point 110 timers for being sent to UE 100 can be arranged to identical value or different values.

Hereinafter, description by the case of shown in fig. 3 it is according to an embodiment of the present disclosure wireless access point 110 from RAN controlled entity 130 receives the indicator of the necessity of the new location register of notice UE 100 and receives timer In the case where or fail to receive RAN controlled entity 130 and wireless access point 110 in the case where both indicator and timer Operation composition.

Indicator both is not received from RAN controlled entity 130 in wireless access point 110 or is not received from it to timer In the case of, it is necessary to release immediately wireless connection before the new location register in request network as far as possible by UE 100.

To detect the new location register for needing UE 100, RAN controlled entity 130 is as much as possible immediately to wireless Access point 110 sends UE context release command message.For example, just sending the NAS that notice location register is refused to UE 100 After message, UE context release command message can be sent to wireless access point 110.In addition, working as from RAN controlled entity 130 When receiving UE release command message, the wireless connection of the releasable UE 100 of wireless access point 110.For example, being controlled when from RAN When entity 130 receives UE context release command message, wireless access point 110 can send the release of UE context to UE 100 RRCConnectionRelease message.In addition, when receiving connection release message from wireless access point 110, UE 100 It is releasable to be wirelessly connected.

In the case where wireless access point 110 receives indicator and does not receive timer from RAN controlled entity 130, Wireless access point 110 knows UE 100 in the situation for the location register that please be looked for novelty.To which wireless access point 110 can utilize The situation that indicator recognizes the need for new location register releases immediately the wireless communication of UE 100 later, but regardless of controlled entity 130 UE context release command message is sent.

For example, wireless access point 110 is immediately to UE if receiving indicator by UE context release command message 100 send RRCConnectionRelease message, and if by another type of message sink to indicator, wirelessly Access point 110 can send RRCConnectionRelease message to UE 100 immediately, this is even released receiving UE context Before putting command messages.

If receiving timer from RAN controlled entity 130, wireless access point 110 can be by starting from appropriate time Timer is indicated or in time for indicating release UE 100 wireless communication.Timer is responsible for the function of agreement.For example, UE 100 do not request indicated by the timer received from wireless access point 110 or in time for indicating to RAN controlled entity 130 Location register.The example for being suitable for starting the time of timer includes time that wireless access point 110 receives timer.

Next, description is by 100 weight of UE under situation as depicted in figure 3 according to another embodiment of the present disclosure It is new to be formed using wireless connection with the process for the location register that look for novelty.

If not receiving the new location register necessity indicator and timer two for UE 100 in operation 320 Person, then it is necessary to maintain to be wirelessly connected in predetermined lasting time to reuse UE 100 for wireless access point 110 Existing wireless connection is to execute new location register.Predetermined lasting time can be true by the unique timer of wireless access point 110 It is fixed.

To which if recognizing the need for the new location register of UE 100 in operation 310, RAN controlled entity 130 exists In operation 320 UE context release command message can not be sent to wireless access point 110.Although being received from RAN controlled entity 130 To UE context release command message, but wireless access point 110 may wait for wireless connection of the predetermined time without discharging UE 100.

If the location register that UE please look for novelty when waiting the predetermined time to wireless access point 110, wireless access point 110 The UE context release command message received from RAN controlled entity 130 may be ignored so that not discharging the wireless of UE 100 Connection.

In the case where only receiving indicator from RAN controlled entity 130 and not receiving timer, wireless access point 110 determine UE 100 in the location register that please be looked for novelty.To if discharged with UE context transmitted by RAN controlled entity 130 Command messages are independently based upon indicator and determine the new location register for needing UE, then wireless access point 110 is waited from UE 100 New position register request is received without discharging its wireless connection.The waiting time of wireless access point 110 can be in wireless access point It is maintained before 110 unique timer time-out.

In the case where receiving timer from RAN controlled entity 130, wireless access point 110 is lighted from specific time Timer is indicated or the wireless connection of UE 100 is maintained in duration for indicating.Timer is seen as the function of agreement Energy.For example, UE 100 sends new position register request indicated by the timer received or in time for indicating.It is suitable for The example of the time of beginning timer includes the time that wireless access point 110 receives timer.

Hereinafter, description is specifically by UE's 100 according to various embodiments of the present disclosure in the case of figure 3 Operation composition.

In accordance with an embodiment of the present disclosure, if the operation 330 in Fig. 3 does not receive timer (with location register from network It is related), then UE 100 may wait for until being wirelessly connected and/or NAS (Non-Access Stratum) signaling is released to by wireless access point 110 Only, and if be wirelessly connected it is released, the location register that UE 100 please look for novelty.

UE 100 can also be used the replacement method of the above method to carry out the location register that please be looked for novelty.That is, if waiting to be released It is wirelessly connected and/or the predetermined lasting time of NAS (Non-Access Stratum) signaling passes, then UE 100 discharges wireless access point 110 Wireless connection and/or NAS (Non-Access Stratum) signaling, and establish the new request for location register.Predetermined lasting time is bright The aobvious instruction specified duration.For example, predetermined lasting time can be the value of the timer of the T3440 timer of UE 100 (i.e. 10 seconds).

If receiving timer in operation 330, UE 100 can be at least indicated by the timer or time for indicating The location register that please be look for novelty after passing.It is released if be wirelessly connected before the timer expiry, UE stops timer simultaneously The location register that please be look for novelty.
