The term used in following description and claim and vocabulary are not limited to philogy implication, and inventor uses these terms and vocabulary to be only used to realize knowing and consistent understanding the disclosure.Therefore, to it will be clear for those skilled in the art that the following description to various embodiment of the present disclosure only provides for illustrational object, be not intended to as claims and equivalent thereof the disclosure that limits limit.

Be appreciated that singulative " ", " one " comprise plural reference, unless context clearly separately has instruction.Thus, such as, mentioning one or more surface is like this comprised to mentioning of " assembly surface ".

Although various embodiment of the present disclosure is for observing the Radio Access Network (RAN) in the 3rd generation partner program (3GPP) standard long-term evolution (LTE) and evolution block core (EvolvedPacketCore as core network, EPC), but theme of the present disclosure can without departing from the scope of the disclosure with a small amount of operational applications to the communication system of other type with similar techniques background, and the technical staff by field of the present disclosure is understood by this.

The legacy system mutual from wherein subscriber equipment (UE) 100 and WAP (wireless access point) 110 is different, recent system allow UE100 and one or more WAP (wireless access point) 110 and 115 mutual.As mentioned above, Fig. 1 shows two WAP (wireless access point) 110 and 115 being connected to UE100.But the disclosure is not limited to the embodiment of Fig. 1, and obviously, UE100 may not be always mutual with two WAP (wireless access point) 110 and 115.

If in the whole text in specification unless otherwise stated, mention an access point 110, then this indicates general WAP (wireless access point); And if mention two WAP (wireless access point) 110 and 115 together, then this indicates the first WAP (wireless access point) to be the main WAP (wireless access point) 110 mutual with it of UE100, and the second WAP (wireless access point) secondary WAP (wireless access point) 115 mutual with it that be UE100.If the quantity of the WAP (wireless access point) that UE100 is connected to is 3 or more, then the quantity of mutual with UE100 strategic point WAP (wireless access point) can be one or more.

In above-mentioned network configuration, following point can occur.Problem will spend long-time for the location register of trial again to respective wireless access point 110 because certain reason fails the UE100 of registration location, and another problem is when the connection status of the WAP (wireless access point) 110 mainly mutual with UE worsens, follow the connection status of its mutual WAP (wireless access point) 115 not to be considered with UE strategic point, thus cause the wasting of resources.Problematic situation is explained in more detail.

Fig. 2 is the diagram that cause the situation of first problem of diagram according to embodiment of the present disclosure.

With reference to Fig. 2, UE100 can utilize the service from mobile communication system to be registered and/or receive service from mobile communication system, and the different RAN controlled entity groups that this mobile communication system utilizes different wireless access technologys (RAT) and/or has a different RAN controlled entity group identifier operate.UE can be in idle condition.

If as reference number 210 represent UE100 from another RAT or another RAN controlled entity group mobility, such as move to region 300 from region 200, then UE100 sends tracking area update (TAU) request message to RAN controlled entity 130.Or if occur being sent to network and/or any data from network reception at UE100 place as representedly in reference number 215, then UE sends service request information to RAN controlled entity 130.The message of RAN controlled entity 130 is sent to by WAP (wireless access point) 110 relaying from UE100.

If gone wrong when receiving TAU request message or service request information from UE100, then RAN controlled entity 130 can send the message of the request message of refusal UE100 to UE100, that is, TAU refuse information or Service Reject message.RAN controlled entity 130 can comprise the information of the reason describing and/or infer problem in refuse information.Refuse information is sent to UE100 by from RAN controlled entity 130 via WAP (wireless access point) 110.

If receive refuse information from RAN controlled entity 130 as representedly in reference number 240, then UE100 can be as represented in reference number 280 send to RAN controlled entity 130 and comprise the new of the reason of carrying in refuse information and enclose request message.The example of reason can comprise RAN controlled entity 130 and fail the situation of the identifier obtaining UE100, and UE100 is by the situation of separating in the dark, and the situation of basic un-activation beared information.These three reasons match with cause value 9,10 and 40 respectively in evolved packet system (EPS).

After sending refuse information to UE100, RAN controlled entity 130 can discharge the context about UE100 as ground order WAP (wireless access point) 110 represented by reference number 240.This order can use UE context release command message to transmit.

If receive release command from RAN controlled entity 130, then WAP (wireless access point) 110 can send request the message of Connection Release to UE100.The example being sent to the connection release message of UE100 from WAP (wireless access point) 110 comprises RRCConnectionRelease message.

If be sent to the release message arrival of UE100 from WAP (wireless access point) 110 and therefore send the new time of enclosing request message more early to the time that the wireless connections of network are completely released such as reference number 280 represented ground UE100 to RAN controlled entity 130 as representedly in reference number 260, then UE100 can perform this no problemly enclose process.

Otherwise, if be sent to the release message arrival of UE100 from WAP (wireless access point) 110 and therefore send the new time of enclosing request message later to the time that the wireless connections of network are completely released such as reference number 280 represented ground UE100 to RAN controlled entity 130 as representedly in reference number 260, then problem can occur.Also namely, this situation represents that UE100 sends to RAN controlled entity 130 and encloses request message, and then wireless connections are released.Thus this is regarded as the problematic situation in the process of enclosing and waits for that the relatively long time (such as 10 seconds) is again to attempt location register by UE100.When waiting long, UE100 can not receive service and therefore user suffers inconvenience.

Describe and be made up of the embodiment of the present disclosure for solving problem described in reference diagram 2.But the problem that will solve is not limited to situation as shown in Figure 2, but comprises and obviously increase all scenario that the UE failing to carry out location register due to certain reason utilizes the time of respective wireless access point again needed for executing location registration.

In order to overcome the above problems, contact two different embodiments and describing the disclosure.But, it will be apparent to one skilled in the art that, can to hereinafter carrying out all available amendments by being described the various embodiments realizing technical conceive of the present disclosure.

With reference to Fig. 2, embodiment of the present disclosure has following character: its time of advent making to be sent to the release message of UE100 from WAP (wireless access point) sends the new time of enclosing request message prior to such as reference data 280 represented ground UE100 to RAN controlled entity 130 as representedly in reference number 260.

Another embodiment of the present disclosure has following character: it avoids the connection between UE100 and WAP (wireless access point) 110 to be released, and namely cancels the operation represented by the reference number 260 in Fig. 2.According to the present embodiment, release message is not sent to UE100 by from WAP (wireless access point) 110.

Whether the difference between above two different embodiments is for reusing wireless connections.Also namely, the feature of previous embodiment is to discharge at all costs at UE100 place connection between UE100 and WAP (wireless access point) 110 for new location register.The feature of a rear embodiment is to reuse the wireless connections of previously setting up and the connection do not discharged between UE100 and WAP (wireless access point) 110, so that the location register that please look for novelty.

These two different all can the avoiding the arrival of the release message owing to being sent to UE100 from WAP (wireless access point) 110 of embodiment and the time discharging wireless connections at UE100 to after RAN controlled entity 130 sends the time of new position register request, thus avoid UE to wait long again asking location register, cause the minimizing of time of delay.

Fig. 3 is the signal flow graph of diagram according to the signal stream between the UE of embodiment of the present disclosure and network, and in more detail, show RAN controlled entity sends operation from one of the timer that the designator of necessity of the new location register of indicating terminal and RAN controlled entity or WAP (wireless access point) send to UE to WAP (wireless access point).

The situation needing new location registration can be known with reference to Fig. 3, UE100 and WAP (wireless access point) 110.UE100 or WAP (wireless access point) 110 can send based on timer the message triggering new location registration or wireless connections dispose procedure.

RAN controlled entity 130 can determine the necessity of the new location register of UE100 in operation 310 under specific problematic situation.As mentioned above, problematic situation can be and at least one the corresponding situation in the cause value 9,10 and 40 used in EPS.RAN controlled entity 130 can have the location register of UE100 or the character of service request in the determination that operation 310 is made.

RAN controlled entity 130 can to WAP (wireless access point) 110 transmission timer and at least one in the designator of the necessity of the new location register of notice UE100.The information being sent to WAP (wireless access point) 110 from RAN controlled entity 130 can be carried down link NAS transport messages.Down link NAS transport messages is used to carry Non-Access Stratum (Non-AccessStratum, the NAS) message between UE100 and RAN controlled entity 130.The example of the NAS message of carrying in down link NAS transport messages comprises TAU refusal and service-denial.The information being sent to WAP (wireless access point) 110 from RAN controlled entity 130 can use for ordering the UE context release command message of UE100 release connection to send.

The designator of the necessity of the new location register of notice UE100 can be expressed by various ways.Such as, designator can utilize the reason of the new location register necessity situation of simple binary message or UE or cause value to express.

WAP (wireless access point) 110 can in operation 330 to UE transmission timer.Timer can be included in the NAS message of carrying in DLInformationTransfer message or DLInformationTransfer message.

Be sent to the timer of WAP (wireless access point) 110 from RAN controlled entity 130 in operation 320 and identical value or different values can be set to from the timer that WAP (wireless access point) 110 is sent to UE100.

Hereinafter, describe and be made up of according to the operation of RAN controlled entity 130 and WAP (wireless access point) 110 when WAP (wireless access point) 110 receives the designator of the necessity of the new location register of notice UE100 from RAN controlled entity 130 and receives timer or failing to receive designator and timer of embodiment of the present disclosure when shown in figure 3.

When WAP (wireless access point) 110 both not from RAN controlled entity 130 receive designator also do not receive timer from it, UE100 be necessary as far as possible request network in new location register before discharge wireless connections immediately.

Thus the new location register needing UE100 detected, RAN controlled entity 130 sends UE context release command message to WAP (wireless access point) 110 as much as possible immediately.Such as, just after the NAS message sending notice location register refusal to UE100, UE context release command message can be sent to WAP (wireless access point) 110.In addition, when receiving UE release command message from RAN controlled entity 130, WAP (wireless access point) 110 can discharge the wireless connections of UE100.Such as, when receiving UE context release command message from RAN controlled entity 130, WAP (wireless access point) 110 can send UE context release RRCConnectionRelease message to UE100.In addition, when receiving connection release message from WAP (wireless access point) 110, UE100 can discharge wireless connections.

When WAP (wireless access point) 110 receives designator from RAN controlled entity 130 and do not receive timer, WAP (wireless access point) 110 knows the situation of UE100 at the location register that please look for novelty.Thus WAP (wireless access point) 110 can discharge the radio communication of UE100 immediately after utilizing designator to identify to need the situation of new location register, and sends regardless of the UE context release command message of controlled entity 130.

Such as, if receive designator by UE context release command message, then WAP (wireless access point) 110 sends RRCConnectionRelease message to UE100 immediately, and if pass through the message sink of another type to designator, then WAP (wireless access point) 110 can send RRCConnectionRelease message to UE100 immediately, and this is even before receiving UE context release command message.

If receive timer from RAN controlled entity 130, then WAP (wireless access point) 110 can indicated by the timer starting from appropriate time or discharge the radio communication of UE100 in the time represented.The function of arranging is responsible for by timer.Such as, UE100 indicated by the timer received from WAP (wireless access point) 110 or represent time in do not ask location register to RAN controlled entity 130.The example being suitable for the time starting timer comprises the time that WAP (wireless access point) 110 receives timer.

Next, describe and form with the process of the location register that please look for novelty by reusing wireless connections according to the UE100 of another embodiment of the present disclosure as depicted in figure 3 when.

If the new location register necessity designator do not received in operation 320 for UE100 and timer, then WAP (wireless access point) 110 is necessary to maintain wireless connections in predetermined lasting time so that the wireless connections making UE100 reuse to have existed are to perform new location register.Predetermined lasting time can be determined by the unique timer of WAP (wireless access point) 110.

Thus if identify the new location register needing UE100 in operation 310, then RAN controlled entity 130 can not send UE context release command message to WAP (wireless access point) 110 in operation 320.Although receive UE context release command message from RAN controlled entity 130, WAP (wireless access point) 110 can be waited for the scheduled time and not discharge the wireless connections of UE100.

If UE is the location register that please look for novelty to WAP (wireless access point) 110 when waiting for the scheduled time, then WAP (wireless access point) 110 may ignore the UE context release command message that receives from RAN controlled entity 130 to make not discharge the wireless connections of UE100.

When not receiving timer when only receiving designator from RAN controlled entity 130, WAP (wireless access point) 110 determines that UE100 is at the location register that please look for novelty.Thus, if the UE context release command message sent with RAN controlled entity 130 determines to need the new location register of UE independently based on designator, then WAP (wireless access point) 110 is waited for and is received new position register request from UE100 and do not discharge its wireless connections.The stand-by period of WAP (wireless access point) 110 can be maintained before the unique timer time-out of WAP (wireless access point) 110.

When receiving timer from RAN controlled entity 130, WAP (wireless access point) 110 is maintaining the wireless connections of UE100 indicated by the timer lighted from special time or in the duration represented.Timer can be counted as the function of arranging.Such as, UE100 indicated by the timer received or represent time in send new position register request.The example being suitable for the time starting timer comprises the time that WAP (wireless access point) 110 receives timer.

Hereinafter, description is made up of the operation of the UE100 according to various embodiment of the present disclosure in the case of figure 3 specifically.

According to embodiment of the present disclosure, if in the operation 330 (relevant with location register) not from network reception to timer of Fig. 3, then UE100 can wait for until wireless connections and/or NAS (Non-Access Stratum) signaling are discharged by WAP (wireless access point) 110, and if wireless connections are released, then the location register that please look for novelty of UE100.

UE100 also can use the replacement method of said method to carry out the location register that please look for novelty.Also be, if passed etc. the predetermined lasting time of wireless connections to be released and/or NAS (Non-Access Stratum) signaling, then UE100 discharges wireless connections and/or NAS (Non-Access Stratum) signaling to WAP (wireless access point) 110, and sets up the new request for location register.Predetermined lasting time obviously indicates the specified duration.Such as, predetermined lasting time can be the value (namely 10 seconds) of the timer of the T3440 timer of UE100.

If receive timer in operation 330, then UE100 can at least indicated by timer or represent go by after the location register that please look for novelty.If wireless connections are released before the timer expiry, then UE stops timer and the location register that please look for novelty.

Terminal 100 can based on from network reception to message, such as location register refuse information, knows the necessity of new location register, and therefore in view of time decreased as much as possible immediately discharge wireless connections be efficient.Thus when the message receiving instruction wireless connections release from WAP (wireless access point) 110, UE100 lingeringly can not depart from connection status.The information of the situation needing new location registration can be the information received on NAS layer to allow UE know.In order to make UE100 lingeringly not depart from connection status, this information is sent to rrc layer by NAS layer.

Current UE 100 is designed to the duration when receiving wireless connections release message from WAP (wireless access point) 110 in certain situations, wireless connections dispose procedure being postponed 60ms.Thus, in embodiment of the present disclosure, if UE100 " not lingeringly " departs from connection status, then this means that UE " from the 60ms received message " or " without the need to waiting for 60ms " just depart from connection status.

According to another embodiment of the present disclosure, if do not receive timer in the operation 330 of Fig. 3, then UE100 can send new position register request to RAN controlled entity 130 immediately after operation 330.If receive timer in operation 330, then UE100 can indicated by timer or represent duration in send new position register request to RAN controlled entity 130.。

Whether UE reuses wireless connections can be depending on situation to determine for new location register in another embodiment.

According to embodiment of the present disclosure, RAN controlled entity 130 can be that the operation 310 of Fig. 3 needs to start timer during the new location register of UE100.This timer can be identical or different with the timer being sent to WAP (wireless access point) 110 from RAN controlled entity 130.The timer of RAN controlled entity 130 can be in operation 320 in designator and timer at least one be sent to WAP (wireless access point) 110 by location register message after or start in this moment.

If UE sends new position register request to RAN controlled entity 130 before the timer expiry, then RAN controlled entity 130 does not discharge wireless connections by sending UE context release command message to WAP (wireless access point) 110 to perform the location register of UE100.Also namely, utilize to wireless connections reuse executing location registration.If UE100 attempts location register in this way before the timer expiry, then RAN controlled entity 130 stops or expiration timer when receiving position register request message.

Otherwise if UE100 does not send new position register request before the timer expiry, then RAN controlled entity 130 triggers wireless connections release.Wireless connections release triggers by sending UE context release command message to WAP (wireless access point) 110.

Fig. 4 is the signal flow graph of diagram according to the signal stream between the RAN controlled entity of embodiment of the present disclosure and WAP (wireless access point).

As mentioned above, according to another embodiment of the present disclosure, even if when RAN controlled entity 130 is by sending the release of this context of UE context release command message order to WAP (wireless access point) 110, WAP (wireless access point) 110 also can not discharge UE context or wireless connections.Thus to RAN controlled entity 130, WAP (wireless access point) 110 can notify that UE context or wireless connections are not released.If UE100 is by reusing the location register that the wireless connections of having set up to look for novelty, then following can be necessary: WAP (wireless access point) 110 maintains wireless connections in predetermined lasting time, even if also like this when receiving context release or wireless connections release message from RAN controlled entity 130 as mentioned above.

The message of the context release of order UE100 can be sent to WAP (wireless access point) 110 in operation 410 with reference to Fig. 4, RAN controlled entity 130.UE context release command message can be comprised in the example of the message of operation 410 transmission.After receiving this message from RAN controlled entity 130, WAP (wireless access point) 110 can not perform context release or wireless connections release and no matter from RAN controlled entity order how.

In operation 420, by sending a notification message to RAN controlled entity 130, WAP (wireless access point) 110 notifies that UE context or wireless connections are not yet released.UE context Release complete can be comprised and Indication message of makeing mistakes in the example of the message of operation 420 transmission.The message being sent to RAN controlled entity 130 from WAP (wireless access point) 110 can comprise notice UE context or the not yet d/d information element (IE) of wireless connections.The example of the IE that can carry within the message comprises cause value and designator.

The message being sent to RAN controlled entity 130 from WAP (wireless access point) 110 can be the message of newtype.When carrying during the IE notifying not run the release that UE is correlated with is by the message at newtype, in an embodiment, new information can be called as UE context release failure message.
