Fig. 1 is the flow chart of RAN congestion processing method embodiment one of the present invention.As shown in Figure 1, the method that the present embodiment provides can by subscriber equipment (User Equipment, be called for short: UE) perform, be integrated in UE with the form of software or hardware, the method that the present embodiment provides specifically can comprise:

Step 101, object UE receive the first notification message that RAN entity sends, and described first notification message carries the congested indication information in RAN user face, and the medium stream information of described object UE.

Described first notification message can pass through (Radio Resource Contorl, be called for short: the RRC) signaling of layer, object UE is sent to as downlink information transmits signaling, wherein, the congested indication information in RAN user face is used for notification target UE, now there is congestion situation in RAN entity, and the medium stream information of object UE is specifically as follows the bearing identification on UE, and the Media Stream in the carrying that described bearing identification is corresponding is Media Stream that is comparatively large to the load effect of RAN entity, that need object UE to regulate.If RAN entity can parse media flow type or the application type of transmission in UE carrying, namely RAN side entity specifically can judge that the Media Stream of a certain type in object UE or a certain application type consume the resource, comparatively large to the load effect of RAN of more RAN entity, then medium stream information also can be specifically media flow type or application message.Wherein, application message can be the information such as microblogging or QQ, and the present embodiment does not limit this.

It should be noted that, in the first notification message, can also carry and be used to indicate object UE deexcitation access network discovery and selection function unit (Access Network Discovery and Selection Function, be called for short: ANDSF) the deexcitation indication information of strategy, when this deexcitation indication information is used to indicate that object UE is follow-up carries out triage operator to the Media Stream on it, if when the ANDSF strategy on it contradicts with triage operator, object UE deexcitation ANDSF strategy, thus make object UE according to the instruction in the first notification message, can process Media Stream, congested to alleviate RAN user face.

Step 102, described object UE are after receiving described first notification message, and the Media Stream corresponding to described medium stream information according to described medium stream information processes.

In actual application, if medium stream information is the bearing identification in object UE, then object UE processes the Media Stream in carrying corresponding to the bearing identification in described object UE; If medium stream information is media flow type, or application message, then object UE processes media flow type corresponding on it or Media Stream corresponding to application message.

It should be noted that, carrying out process to Media Stream can be: by media stream shunting, to the attachable WLAN of object UE, (Wireless Local Area Networks, is called for short: WLAN); Or object UE and network side consult the coded system of Media Stream again, and send or the data of receiving media stream according to new coded system, the present embodiment does not limit the processing mode of Media Stream.

Further, if object UE is selected the mode of media stream shunting to the attachable wlan network of object UE, this step also comprises: when ANDSF policy conflict on described media stream shunting and described object UE, after ANDSF strategy described in described object UE deexcitation, by described media stream shunting in the attachable wlan network of described object UE.

The method realizing such scheme can be: if carry deexcitation indication information in the first notification message received, accordingly, when the ANDSF strategy of described object UE contradicts with triage operator, and deexcitation ANDSF strategy; Alternatively, also can be after receiving the first notification message, no matter whether carry described deexcitation instruction in described first notification message, when ANDSF strategy contradicts with triage operator, the automatic deexcitation ANDSF strategy of UE, thus object UE can be processed Media Stream, congested to alleviate RAN user face.

The technical scheme of the present embodiment, the first notification message is received by object UE, and in the first notification message, carry the information of the Media Stream of object UE, the Media Stream making object UE corresponding to medium stream information according to described medium stream information processes, thus object UE is processed for the Media Stream taking resource more, effectively reduce the use of resource, the user face alleviating RAN is congested.

On the basis of above-described embodiment, if the user face of RAN entity is congested be effectively eased after, object UE receive that RAN entity sends for notification target UE, after the second notification message of RAN user face congestion relief, the Media Stream after process is reverted to state before treatment.

Further, if the ANDSF strategy of UE deexcitation on it, then object UE is after receiving described second notification message, reactivates described ANDSF strategy.

It should be noted that in addition: if UE leaves congested cell, or current business terminates, before initiation new business, the ANDSF strategy on it is activated automatically.

Fig. 2 is the flow chart of RAN congestion processing method embodiment two of the present invention, and as shown in Figure 2, the method that the present embodiment provides can be performed by UE, in a user device integrated with the form of software or hardware, and the method that the present embodiment provides specifically can comprise:

Step 201, object UE receive the data that RAN entity sends, and described data carry the congested instruction in RAN user face.

Alternatively, described data can also carry the deexcitation indication information being used to indicate described object UE deexcitation ANDSF strategy, when this deexcitation indication information is used to indicate that object UE is follow-up carries out triage operator to the Media Stream on it, if during described ANDSF policy conflict in described triage operator and described object UE, after ANDSF strategy described in described object UE deexcitation, by described media stream shunting in the attachable wlan network of described object UE, thus make object UE according to the instruction in described data, Media Stream is processed, the user face alleviating RAN entity is congested.

If RAN entity is resolved data, determine the media flow type that consumption of natural resource is more or application type, then can increase the congested indication information in RAN user face, so that object UE processes the Media Stream on the Media Stream at data place or place carrying after receiving the data carrying the congested indication information in RAN user face in the data of the more media flow type of described consumption of natural resource or data type.

Step 202, described object UE after receiving the data, process the described Media Stream that Media Stream or the described data place at described data place carry.

In this step, UE is after receiving the data of carrying the congested indication information in RAN user face, all Media Streams in the carrying of data place are processed, optionally, UE can process the Media Stream of the application at this data place, or Media Stream corresponding to the medium type of UE to these data processes.

It should be noted that, can comprise Media Stream process: by media stream shunting in the attachable wlan network of object UE; Or object UE and network side consult the coded system of Media Stream again, and send or the data of receiving media stream according to new coded system, the present embodiment does not limit the processing mode of Media Stream.

If UE is in wlan network by media stream shunting to the processing mode of Media Stream, this step further comprises: when carrying described deexcitation indication information in the described data that described object UE receives, if when the ANDSF strategy of described object UE contradicts with triage operator, UE deexcitation ANDSF strategy; Alternatively, whether carry described deexcitation instruction in the congested data in RAN user face of carrying no matter UE receives, when ANDSF strategy contradicts with triage operator, UE can deexcitation ANDSF be tactful automatically, thus object UE can be processed Media Stream, congested to alleviate RAN user face.

The technical scheme of the present embodiment, after carrying the data of the congested indication information in RAN user face by object UE reception, the Media Stream that Media Stream or the data place at data place carry is processed, thus object UE is processed for the Media Stream taking resource more, effectively reduce the use of resource, the user face alleviating RAN entity is congested.

On the basis of above-described embodiment, if after RAN entity congested be effectively eased, object UE receives the data that RAN entity sends, and carries the congestion relief instruction of RAN user face in data, and the Media Stream after process can be reverted to state before treatment by UE.

Further, if described object UE ANDSF strategy described in deexcitation when performing described media stream shunting, then described object UE is after receiving the data of carrying the congestion relief instruction of RAN user face, reactivates described ANDSF strategy.It should be noted that in addition: if UE leaves congested cell, or current business terminates, before initiation new business, the ANDSF strategy on it is activated automatically.

Fig. 3 is the flow chart of RAN congestion processing method embodiment three of the present invention.As shown in Figure 3, on the basis of above-described embodiment, before step 101 or step 201, the method that the present embodiment provides can also comprise:

Step 301, described UE receive described RAN entity send, be used to indicate the Indication message reporting WLAN signal situation.

Described UE can also be all UE under RAN entity coverage cell.

In this step, RAN entity can be used to indicate to described UE transmission the Indication message reporting WLAN signal situation by RRC connection reconstruction message, can be specifically in UE attaching process, RAN entity reports the parameter of WLAN signal situation by configuration UE in the RRC connection reconstruction message that sends to UE, reports WLAN signal situation to make described UE, optionally, core network entity, as mobile management entity (Mobility Management Entity, be called for short MME) or Serving GPRS Support Node (Serving GPRS Support Node, be called for short: SGSN), can in UE attaching process, judge whether to need this UE to report WLAN signal situation according to preset criterion, as the UE that MME/SGSN can only select priority lower, or the UE of roaming, or the larger UE of data volume reports WLAN signal situation, if subscriber equipment meets preset criterion, then increase the parameter that instruction UE reports WLAN signal situation in the initial context setup request message of MME/SGSN in attaching process, RAN entity receives with after the initial context setup request message reporting WLAN signal situation parameter, send RRC connection reconstruction message, and configuration UE reports the parameter of WLAN signal situation in RRC connection reconstruction message, WLAN signal situation is reported to make described UE.

Step 302, described UE detect described WLAN signal, and when WLAN signal meets pre-conditioned, report WLAN signal situation.

In actual application, can configure in Indication message and report threshold value, after described UE receives Indication message, detect WLAN signal, in WLAN signal higher than high thresholdhigh, or prescribe a time limit lower than under threshold value, report WLAN signal situation, such as, if WLAN signal is higher than high thresholdhigh, report UE to have attachable WLAN to RAN entity, if WLAN signal is lower than threshold value lower limit, report UE there is no attachable WLAN to RAN entity.Particularly, described UE can report WLAN signal situation by measurement report message.
