The citing of five possible implementations be will be given below previous embodiment to be further detailed.Below In example, 3GPP RAN can be eNB and be also possible to RNC, and the embodiment of the present invention not limits this, and WLAN devices are then It can be WLAN AP(Access Point, access point).

Example one:

The present embodiment is mainly the scheme for solving RRC Connection Release.Its main thought is, after the service ending of user, UE reports instruction information to RAN, and the business of RAN user is notified to be over；To trigger the RRC between RAN release UE and RAN Connection.Referring to Fig. 3, detailed process is as follows:

301:UE initiates to access in 3GPP, is linked into 3GPP RAN.

302:RAN determines UE being diverted to WLAN AP by information such as measurement reports.

303:UE is linked into WLAN AP and carries out data transmission；The RRC connection between 3GPP RAN and UE is still kept not at this time Release.

304: after the service ending of user, UE reports instruction information to RAN, and the business of RAN user is notified to be over.

For example, user downloads a file, file download is completed, then UE reports RRC information to RAN, and above-mentioned RRC information is taken Band instruction information, the business for being used to indicate user are over, and in more detail, indicate that all business of user are all over.

The RRC information that above-mentioned RRC information may be newly introduced, is also possible to existing RRC information, such as RAN Indicate that user monitors customer service in measuring configuration, UE reports information notice RAN by measurement report, and " customer service is Terminate ".

After 305:RAN receives the instruction information, sends RRC Connection Release (RRC connection release) message and give UE discharges RRC connection.

Example two:

The present embodiment is mainly the another program for solving RRC Connection Release.Its main thought is divided in UE business After WLAN, it is fixed then to restart first if there is data are transmitted for data transmission scenarios of the starting first timer monitoring UE on WLAN When device.If first timer time-out (that is: not having data transmission during the timing of first timer), it is determined that UE and WLAN Between no data send, data transmission it is inactive；Then UE reports instruction information to RAN, notifies RAN user's nothing within the regular hour Data transmission；To trigger the RRC connection between RAN release UE and RAN.Referring to Fig. 4, detailed process is as follows:

401:UE initiates to access in 3GPP, is linked into 3GPP RAN.

402:RAN determines UE being diverted to WLAN AP by information such as measurement reports.

403:UE is linked into WLAN AP and carries out data transmission；The RRC connection between 3GPP RAN and UE is still kept not at this time Release.

404:UE starts first timer, starts timing, and detect whether carried out data biography between UE and WLAN AP It is defeated, first timer is restarted if having carried out data transmission, has been carried out data transmission if not detecting, has been continued to test, Until first timer time-out.

The duration of above-mentioned first timer timing can be RAN and be handed down to UE, for example, carrying first in order shunting The duration information of timer, or in measuring configuration carry first timer duration information.Above-mentioned first timer timing Duration is also possible to a time value of the duration of the timer timing less than or equal to the side RAN of configuration.First timer timing Duration how to obtain, the embodiment of the present invention not limit.

405: after first timer time-out, UE reports RRC information to RAN, and above-mentioned RRC information carries instruction information, is used for No data is sent in indicating user at the appointed time.

This step is specifically: following period of time (definitely, in the time of the duration of first timer timing) UE with There is no data transmission between WLAN AP, then first timer time-out, this illustrates that user is in data and transmits sluggish state. UE reports RRC information to RAN, and above-mentioned RRC information carries instruction information, is used to indicate user's interior no data hair at the appointed time It send.

The RRC information that above-mentioned RRC information may be newly introduced, is also possible to existing RRC information, such as RAN Indicate that user monitors data transmission and/or carries first timer duration in measuring configuration, UE is reported by measurement report Information notifies RAN " interior no data is sent user at the appointed time ".

After 406:RAN receives above-mentioned instruction information, RRC Connection Release (RRC connection release) message is sent RRC connection is discharged to UE.

Example three:

The present embodiment is mainly the yet another aspect for solving RRC Connection Release.Its main thought is that UE and current AP are disconnected Afterwards, UE reports instruction information to RAN, and RAN UE is notified to disconnect in current AP or no longer carry out on current AP Data transmission；To trigger the RRC connection between RAN release UE and RAN.Referring to Fig. 5, detailed process is as follows:

501:UE initiates to access in 3GPP, is linked into 3GPP RAN.

502:RAN determines UE being diverted to WLAN AP by information such as measurement reports.

503:UE is linked into WLAN AP and carries out data transmission；The RRC connection between 3GPP RAN and UE is still kept not at this time Release.

Whether 504: detection UE disconnect with the AP currently connecting.If so, entering in next step, if otherwise continued to test.

A possibility that UE is disconnected from the AP that currently connects have it is very much, such as: UE comes back home from public domain, at this moment can be with Current AP is disconnected, is then carried out data transmission using the WLAN AP of family to save money spending.

505:UE reports RRC information to RAN, and above-mentioned RRC information carries instruction information, is used to indicate UE current It disconnects in AP and no longer carrying out data transmission on current AP in other words.

The RRC information that above-mentioned RRC information may be newly introduced, is also possible to existing RRC information, such as RAN Indicate that user reports information when disconnecting from AP in measuring configuration, UE reports information notice RAN by measurement report, and " UE exists It is disconnected in current AP ".

After 506:RAN receives the instruction information, sends RRC Connection Release (RRC connection release) message and give UE discharges RRC connection.

Example four:

The present embodiment mainly solve the problems, such as early release RRC connection there may be.Its main thought is, RAN with After the packet data inactivity timer time-out of family, RRC connection is not released immediately, but sends query messages and is presently in UE with obtaining UE State with decide whether discharge RRC connection.As shown in fig. 6, including the following steps:

601:UE initiates to access in 3GPP, is linked into 3GPP RAN.

602:RAN determines UE being diverted to WLAN AP by information such as measurement reports.

603:UE is linked into WLAN AP and carries out data transmission；The RRC connection between 3GPP RAN and UE is still kept not at this time Release.
