The method for controlling user equipment access high-speed mobile instrument communications network

Technical field

The present invention relates to mobile communication technology field more particularly to a kind of method, core network control surface node device, base station and the communication systems of control user equipment access high-speed mobile instrument communications network.

Background technique

High-speed mobile tool is quickly grown in China and global range.For example, high-speed mobile tool includes high-speed railway train (hereinafter referred to as " high-speed rail "), magnetic suspension train, subway etc..By taking high-speed rail as an example, high-speed rail operating mileage has reached 30,000 kilometers or more and is in the trend of rapid growth.Demand that is extensive along with high-end crowd, taking the case where high-speed mobile tool frequently flows and the construction of high-speed mobile tool self-informationization for a long time, the communication requirement of high-speed mobile tool are increasingly strong.

However, high-speed mobile instrument communications are different from conventional indoor and outdoors mobile communication scene, and since train running speed is fast, car body penetration loss is big, scene changeable equal factors with a varied topography, so that existing public network is not suitable for taking the user of high-speed mobile tool and providing service.Therefore, the demand for building the network that one provides service exclusively for high velocity mobile users is outstanding day by day." public network " herein refers to the general wireless cellular communication network for being different from above-mentioned dedicated network.The dedicated network and public network can be different public land mobile network (English: public land mobile network, abbreviation: PLMN)；Alternatively, being also possible to the division of two class network areas under the same PLMN, the two can spatially have overlapping, but use different access frequency points.For example, having there is equipment vendor and operator to start to plan and dispose such high-speed rail ad Hoc wireless network (hereinafter referred to as " high-speed rail private network ") at present.High-speed rail private network covers high-speed rail and advances on the way and near the platform in high-speed rail railway station.The cell deployment in high-speed rail railway station region is as shown in Figure 1A.Waiting room 102, channel out of the station 103 and the platform 104 and cell 106 in high-speed rail railway station are all planned to the private network cell belonged under the covering of high-speed rail private network.Railway station square outside railway station is planned to belong to public network cell 105.The high-speed rail network planning at present independently disposes private network cell and public network cell.The characteristics of for the covering of railway line style, high-speed rail private network takes cell to cascade the scheme continuously covered, as shown in Figure 1B.In the example in fig. 1b, the private network cell 111 that the orbital region of high-speed rail is cascaded continuously covers, while public network cell 115 also covers the orbital region of the high-speed rail.

Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, following will be combined with the drawings in the embodiments of the present invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.

The present invention is for controlling UE access high-speed mobile instrument communications network, so that the UE for belonging to the user of seating high-speed mobile instrument communications network is advancing on the way, even if accessing public network because abnormal cause is detached from high-speed mobile instrument communications network, high-speed mobile instrument communications network can also be come back to.Wherein, high-speed mobile instrument communications network refers to that the dedicated network and public network can be different PLMN to take the user of high-speed mobile tool and provide the dedicated network of communication service；Alternatively, being also possible to the division of two class network areas under the same PLMN, the two can spatially have overlapping, but use different access frequency points (such as 2500Hz, 2600Hz of China Mobile).For ease of description, high-speed mobile instrument communications network is also referred to as the first communication network, public network is also referred to as the second communication network.In addition, the UE used by a user for taking high-speed mobile tool (e.g., high-speed rail, light rail, subway) is referred to as first kind UE, and the non-UE used by a user for taking the mobile tool of speed is known as non-first kind UE.

The first communication network that the present invention is applicable in includes but is not limited to long term evolution (English: Long Term Evolution, referred to as: LTE) network, global system for mobile communications (English: Global System of Mobile communication, referred to as: GSM) or Universal Mobile Telecommunications System (English: Universal Mobile Telecommunications System, referred to as: UMTS) network.Under the scene of any of the above network, communication system includes at least core network control surface node device, UE and base station.Under LTE network, core network control surface node device includes but is not limited to mobility management entity (English: Mobility Management Entity, referred to as: MME), base station includes but is not limited to E-UTRAN NodeB (English: E-UTRAN NodeB, abbreviation: eNodeB).Under GSM network or UMTS network, core network control surface node device includes but is not limited to general packet radio service (English: General Packet Radio Service, referred to as: GPRS) business support node (English: Serving GPRS Support Node, referred to as: SGSN) or mobile switching centre is (English: Mobile Switching Center, referred to as: MSC), base station includes but is not limited to base station controller (English: base station controller, referred to as: BSC) or radio network controller is (English: radio network controller, referred to as: R NC).In the present invention, the first communication network and the second communication network dispose different access network equipments (e.g., eNodeB) respectively.

Below will using high-speed mobile tool as high-speed rail, the first communication network be LTE high-speed rail private network for be described.However, the present invention is not limited thereto, high-speed mobile tool includes but is not limited to high-speed rail, magnetic suspension, subway, and the present disclosure applies equally to GSM network or UMTS networks.

For example, the scene of high-speed rail private network covering can be divided into high-speed rail railway station and high-speed rail advance on the way both.High-speed rail railway station is covered by private network cell, the private network MPS process that high-speed rail traveling is also cascaded on the way.In addition, high-speed rail railway station and travelling route are also all at least covered by the public network cell part near high-speed rail private network.

Fig. 2 show the communication means flow chart of one embodiment according to the present invention.Fig. 2 is by core network control surface node device (such as MME) Lai Zhihang.The MME can be the private network MME that the first communication network is independently disposed, alternatively, the MME can also be the shared MME of the first communication network and the shared deployment of the second communication network, that is, high-speed mobile instrument communications network and public network use the same MME.When MME is by high-speed mobile instrument communications network and shared public network, shared MME is used for while providing control plane management service for first kind UE and non-first kind UE.

In an embodiment of the present invention, first kind UE can access high-speed rail private network in different zones.For example, UE can access high-speed rail private network in region at the train station, alternatively, UE can access high-speed rail private network in orbital region.For example, such as entering waiting room when user enters high-speed rail railway station region and waiting or go on platform through passageway, because it enters the overlay area of high-speed rail private network signal, overwhelming majority booting UE can access high-speed rail private network.

There are many mode of UE access high-speed rail private network is possible, such as: the UE for being in Idle state, because UE enters high-speed rail private network cell from public network cell, so that triggering cell re-selection procedure accesses high-speed rail private network.For being in the UE of connected state, high-speed rail private network can be accessed through LTE switching flow.And the UE being just switched on for entering railway station region (such as waiting room, passageway, platform etc.), it can pass through and initiate attachment (attach) process access high-speed rail private network under region private network cell at the train station.

After the UE AT STATION region access high-speed rail private network, the public network on the private network periphery may be accessed because of abnormal cause (such as terminal abnormal, private network cover difference) disengaging high-speed rail private network.For example, the UE can search periphery public network frequency point and a suitable public network cell is selected to be resident when high-speed rail train operation is very poor or when without private network overlay area to private network covering signal quality.

As shown in Fig. 2, communication means includes:

S200, after the second communication network of UE access, core network control surface node device identifies that the UE is first kind UE.

For example, the UE of MME identification access public network is first kind UE.How MME specifically judges whether UE is that first kind UE will be described further in conjunction with Fig. 3 A and Fig. 3 B.

S202, core network control surface node device send instruction information to the base station for servicing the UE, and it is first kind UE which, which is used to indicate the UE, so that the base station is by first communication network of UE access.

For example, the core network control surface node device sends the instruction information to the base station, so as to which the UE is redirected to first communication network after base station receives the instruction information.How UE will be redirected to the first communication network according to instruction information by base station to be described further in conjunction with Fig. 3 B.

Alternatively, this method further comprises before step S202:

S201, core network control surface node device (such as, MME after) determining that UE is first kind UE, the first wireless access standard/frequency priority user file mark (English Subscriber Profile ID for RAT/Frequency Priority, referred to as: SPID) value is distributed for the UE.Above-mentioned instruction information is the first SPID value.

Correspondingly, then step S202 is specifically included:

The core network control surface node device sends the first SPID value to the base station, and the first SPID value is used to indicate the base station and sends the first frequency point priority letter to the UE Breath, wherein the first frequency point precedence information is used to indicate the UE and the frequency point of first communication network is preferentially selected to be resident.How MME is how UE distribution SPID value and base station send frequency point precedence information according to the SPID value received and will be described further in conjunction with Fig. 3 A.

Scheme through the invention sends instruction information to the base station for servicing the UE, so that the base station is by the first communication network of UE access private network after core network control surface node device determines that UE is first kind UE.Therefore, even if first kind UE (such as advancing on the way) also can rapidly come back to high-speed rail private network, improve the user experience of first kind UE because abnormal cause misconnection enters public network.

Fig. 3 A show the signaling interaction diagram of communication means according to an embodiment of the invention.Method under Fig. 3 A scene is realized by UE 310, MME 320 and public network eNodeB 330 interaction.Wherein, UE 310 is first kind UE.

S301, UE 310 accesses public network because of abnormal cause.

S302, MME 320 identifies that UE 310 is first kind UE, and distributes the first SPID value accordingly for UE 310.

For example, MME 320 can in the following manner in it is any come identify UE 310 be first kind UE.

(1) MME 320 can be the core network control surface node MME independently disposed for high-speed rail private network, be also possible to the MME with the shared deployment of existing public network.In addition, due to setting up the private network base station independently of public network base station in private network cell, and under normal circumstances, it needs to divide and is different from public network tracking area (English: Tracking Area, abbreviation TA) private network TA, such as private network TA contains dedicated tracking area coding (English: Tracking Area Code, abbreviation: TAC).Therefore, can distinguish TA by TAC is private network TA or public network TA.

In addition, can generally be belonged to different TA lists (TA list) by planning because private network TA and public network TA belong to different types of TA.When UE 310 accesses public network TA from former private network TA, TAU process can be initiated.For example, UE 310 sends TAU request message to core network control surface node device MME320, wherein TAU request message carries original TAC (old TAC) cell, and original TAC cell corresponds to private network TAC.

Therefore, step S302 can include:

S302a, core network control surface node device receive the mobile management region of UE transmission more New request message, such as TAU request message.The mobile management area update request message carries former mobile management regional code.

When the former mobile management regional code is the mobile management regional code of first communication network, first core network control surface node device according to the former mobile management regional code (such as, old TAC cell), determine that the UE is first kind UE.

It should be noted that, (such as certain non-first kind UE, do not take the UE used by a user of high-speed rail) access high-speed rail private network the case where, the prior art may be moved out such UE high-speed rail private network by the way of switching, so that a large amount of ordinary users be avoided to occupy the resources of high-speed rail private networks for a long time.Although the old TAC cell of such UE also corresponds to private network TAC, for initiating the UE of TAU process in handoff procedure, even if the old TAC cell that UE is reported corresponds to private network TAC, MME can not be judged as first kind UE.

(2) when UE310 is resident private network (i.e. before access high-speed rail public network), private network/shared 2nd MME first identifies that the UE is first kind UE after UE 310 accesses private network, and the identity information is stored in user's context.Public network/the first shared MME can identify that the UE is first kind UE by private network/shared 2nd MME informing.

Therefore, step S302 can include:

S302b, first core network control surface node device is (such as, the MME 320 of public network/shared) to the second core network control surface node device send user's context request message, such as, when high-speed rail private network and public network independently dispose core network control equipment, the second core network control surface node device can be the core network control equipment of public network.When high-speed rail private network and public network share deployment core network control equipment, the second core network control surface node device is the equipment of the core network that private network and public network are shared；

(3) when private network and public network core network control surface node MME share deployment, the shared MME is when UE 310 resides at private network (namely before access public network), the identified UE is first kind UE, and records reflecting between the UE identity and first kind UE Penetrate relationship.The identity of UE includes but is not limited to international mobile subscriber identity (English: international mobile subscriber identity, abbreviation: IMSI) or globally unique temporary identifier (English: globally unique temporary identity；Referred to as: GUTI).When UE 310 is detached from private network and accesses public network, MME can search the mapping relations of internal record by the identity (e.g., IMSI or GUTI) that UE is reported and determine whether the UE is first kind UE.

Therefore, step S302 can include:

S302c, first core network control surface node device receive the identity that the UE is reported, and determine that the UE is first kind UE according to the identity and the mapping relations.

(4) when UE 310 resides at private network (namely before access public network), UE 310 is identified as first kind UE by private network MME or shared MME, and issues specific identity by private network MME or shared MME.Such as, specific identity can be dedicated GUTI, specific private network MME or shared MME can reassign message by GUTI and issue dedicated GUTI to UE 310, include special mobile management entity coding (English: mobility management entity code in the dedicated GUTI；Referred to as: MMEC).

Therefore, step S302 can include:

S302d, core network control surface node device receives specific identity that the UE is reported (such as, GUTI containing dedicated MMEC), the specific identity is to issue before the second communication network described in the UE access from second core network control surface node device to the UE, it is first kind UE that the specific identity, which is used to indicate the UE, for example, the second core network control surface node device can be the core network control equipment of public network.When high-speed rail private network and public network share deployment core network control equipment, the second core network control surface node device is the first core network control surface node device；

The core network control surface node device determines that the UE is first kind UE according to the specific identity.

(5) core network control surface node MME 320 can also learn that UE 310 is first kind UE by the informing of public network base station 330.Such as, public network base station in the UE access public network/after, measure the speed of the UE (such as, public network base station utilizes the speed of Doppler shift algorithm measurement UE), if the speed of the UE is higher than preset value, the public network base station determines that the UE is first kind UE, and sends notification information to the MME, to notify described in MME UE is first kind UE.

Therefore, step S302 can include:

S302e, the core network control surface node device receive the notification message of the base station, and it is first kind UE that the notification message, which is used to indicate the UE,；

It should be noted that public network base station according to testing the speed for UE is determined UE be first kind UE can also be used in other scenes or purposes, however it is not limited to the description in the present embodiment.

(6) after core network control surface node MME 320 can also be by judging the UE access public network, occur under Idle state TAU process frequency or connected state under the frequency that changes of service ENB be higher than preset value, and identifying UE is first kind UE.

Therefore, specifically, step S302 may include following any:

S302f1, for Idle state UE, if MME 320 identifies that UE 310 triggers mobile management area update process (such as within a preset period of time, TAU process) number be greater than preset value (such as, 1) preset value is greater than, that is, multiple transformation has occurred in the TA where the UE, then MME 320 determines that the UE is first kind UE.

S302f2, for Idle state UE, when UE initiates mobile management area update process (such as, TAU process) when, if MME 320 identifies mobile management area update request message (such as, TAU request message) from the public network eNodeB close to high-speed rail private network, then the UE is paged with setting means and sets number.If MME 320 identifies the message of setting number in the page-response message of UE transmission from different eNodeB and these different eNodeB are to determine that UE is first kind UE close to the public network eNodeB, MME 320 of high-speed rail private network.Wherein, related eNodeB information is configured in MME 320, for determining whether an eNodeB is public network eNodeB close to high-speed rail private network.The mode (setting of such as time interval) of paging UE can refer to the speed of the distance between eNodeB and high-speed rail in public network.

S302f3, for connected state UE, if MME 320 identifies that the number that the base station for serving the UE converts within a preset period of time is greater than preset value, it is determined that the UE is first kind UE.

S302f4, for connected state UE, if MME 320 identifies that the eNodeB of the service UE of setting number is different, and these different eNodeB are proximate to the public network eNodeB of high-speed rail private network, then MME 320 determines that UE is first kind UE.Wherein, it is configured in MME 320 Related eNodeB information, for determining whether eNodeB is public network eNodeB close to high-speed rail private network.After MME 320 identifies that UE 310 is first kind UE by any of the above method, the first SPID value is distributed for the UE.For example, MME 320 is that the UE distributes SPID=5.

S303, MME 320 sends the first SPID value to public network eNodeB 330.Correspondingly, eNodeB 330 receives the first SPID value that MME 320 is sent.

For example, MME 320 sends downlink Non-Access Stratum (English: non-access stratum, abbreviation: NAS) direct-sending message to public network eNodeB 330, the downlink NAS direct-sending message carries the first SPID value.If the MME 320 receives the mobile management area update request message of the transmission of UE 310 (such as, TAU request message), it can also include following any in the downlink NAS direct-sending message: mobile management area update received message or mobile management area update refuse information.

By taking LTE network as an example, after UE 310 sends TAU request message to MME 320, MME 320 can first receive TAU request, be packaged in and be sent to the public network eNodeB 330 for serving the first kind UE in downlink NAS direct-sending message the oneth SPID value and TAU receiving (accept) message.Public network eNodeB 330 parses the downlink NAS direct-sending message received, and to obtain the first SPID value and TAU accept message, the TAU accept message that parsing obtains can be transmitted to UE310 or directly abandoned by public network eNodeB 330.Alternatively, MME 320 can first refuse TAU request, the first SPID value is packaged in TAU refusal (reject) message for carrying certain cause value and issues the public network eNodeB 330 for serving the UE in downlink NAS direct-sending message.For example, the reason of carrying in TAU reject message value, which specifically can be tracking area, not to be allowed in (Tracking area not allowed) or tracking area without suitable cell (No suitable cells in tracking area) etc..The cause value is used to indicate the TAU process that the first kind UE is initiated and is not allowed to, and initiates TAU request to public network TA again to avoid the UE.Public network eNodeB 330 parses the downlink NAS direct-sending message received, and to obtain the first SPID value and TAU reject message, the TAU reject message that parsing obtains can be transmitted to UE310 or directly abandoned by public network eNodeB 330.

Alternatively, it is optional, for LTE network, S303 can include:

MME 320 sends initial context to public network eNodeB 330 and establishes request message (initial context setup request), and the initial context establishes request and disappears Breath is used to indicate the context that the eNodeB 330 establishes the user, and the initial context establishes request message and carries the first SPID value；Or, MME 320 sends context modification request message (UE context modification request) to public network eNodeB 330, the context modification request message is used to provide the change information of user's context to the eNodeB 330, and the context modification request message carries the first SPID value.

Alternatively, optional, S303 can include:

Core network control surface node device MME 320 sends context release order message (e.g., S1 interface context release order message) to the public network base station eNodeB 330, and the context release order message carries the instruction information.

Such as, MME 320 is received after the TAU process that the first kind UE is initiated, the TAU request that the UE is initiated can be accepted or rejected, TAU is completed after MME 320 to handle and complete after TAU accept/reject message issues, MME 320 triggers S1 interface and discharges process, to discharge the signaling plane connection of the UE.MME 320 is sent to the public network base station eNodeB 330 to be carried the S1 interface context of the first SPID value and releases order (S1UE Context Release Command) message, and the first SPID value is for informing that UE described in the public network base station eNodeB 330 is first kind UE.

S304, public network base station 330 determine the first frequency point precedence information according to the first SPID value, and send the first frequency point precedence information to UE 310 accordingly.Correspondingly, UE 310 receives the first frequency point precedence information.First frequency point precedence information is used to indicate the UE and the frequency point of first communication network is preferentially selected to be resident, that is, priority access high-speed rail private network.

Wherein, the mapping relations of different SPID value and various frequency point precedence informations can be pre-configured in eNodeB 330.Therefore, after eNodeB 330 receives the first SPID value, corresponding first frequency point precedence information can be obtained by the mapping relations of query configuration.First kind UE private network frequency point highest priority to be returned is set in mapping relations.For example, can safeguard a mapping table as shown in Table 1 in eNodeB330.

Table 1

As shown in table 1, when SPID is equal to 5, the corresponding preferential group 1 of the first frequency point precedence information, in preferential group 1, the frequency point of public network is 800M, and priority level 6, the frequency point of private network is 2600M, priority level 7.It is assumed that the value of priority level is bigger, the priority for representing the frequency point of the corresponding network is higher, i.e. the frequency point of the big network of UE priority access priority level value.Therefore, when SPID is equal to 5, the first frequency point precedence information indicates that the priority of private network frequency point is higher than the priority of public network frequency point.

After public network base station 330 determines the first frequency point precedence information according to the first SPID value, public network base station 330 sends the first frequency point precedence information to UE 310.

For example, the base station sends radio resource control RRC Connection Release (RRC connection release) message to the UE, the first frequency point precedence information is carried in the RRC connection release message.More specifically, it public network base station can be after the first SPID value for receiving core network control surface node transmission, it is immediately finished the ongoing business of first kind UE (such as TAU process), the RRC connection release message for carrying the first frequency point priority group information is sent, to the UE to discharge the signaling connection of the UE and network side.Alternatively, after public network base station after receiving the first SPID value, waits the UE and network side to complete current ongoing business, then signaling connection between UE and network side is discharged, e.g., the RRC connection release message for carrying the first frequency point priority group information is sent to UE.

S306, UE 310 preferentially selects the frequency point of first communication network to be resident according to the first frequency point precedence information.

After UE 310 accesses public network, user experience decline is obvious, once user's winding-up uses, UE 310 enters Idle state quickly.It is preferential that the corresponding frequency point of high-speed rail private network is selected to be resident according to the first frequency point precedence information after UE 310 receives the first frequency point precedence information of the transmission of public network base station 330 and after entering Idle state.For example, reselecting to the cell if the frequency point that UE 310 searches certain cell in high-speed rail private network is suitably executed re-selection procedure.

By taking LTE high-speed rail private network as an example, under normal circumstances, high-speed rail private network TA and periphery public network TA are deployed as different types of TA, the same TA list are typically not belonged to, so the UE TAU process can be triggered after reselecting to high-speed rail private network cell.The UE sends TAU request message to high-speed rail private network/shared core network control surface node MME, and the old TAC that the TAU request message carries corresponds to public network TAC.The high-speed rail private network/shared core network control surface node (MME) receives the access that the TAU that the UE is initiated requested and allowed the UE.

According to the solution of the present invention, after first kind UE accesses public network because of abnormal cause, core network control surface node device MME can identify that the UE is first kind UE in several ways, and distribute the first SPID value accordingly for the UE, and the first SPID value is sent to public network base station.Public network base station sends the first frequency point precedence information to UE according to the first SPID value received, so that UE 310, after public network enters Idle state, the frequency point for the high-speed mobile instrument communications network that priority can be selected high immediately is accessed.That is, even if UE 310 because abnormal cause misconnection enters public network, also can soon access again high-speed mobile instrument communications network, improve the user experience of first kind UE according to the first frequency point precedence information.

Optionally, the first frequency point precedence information further includes timer value.For example, the timer value can be set according to high-speed rail distance, the factors such as time of train vibration influence.The timer value was used to indicate for the first frequency point precedence information effective duration.For example, timer value is set as a hour, as soon as after hour, which fails.

Therefore, optionally, before step S306, this method further include:

S305, UE 310 is when judging whether the timer expires or not.In the case that the timer of UE 310 is not timed-out, UE 310 executes above-mentioned steps S306.After timer expiry, step S307 is executed.In S307, the network according to corresponding to the high frequency point of other frequency point precedence information access priorities of UE 310.

Due to being provided with the timer of the first frequency point precedence information, after timer expiry, the first frequency point precedence information failure, then, UE 310 can the network according to corresponding to other frequency point precedence information access priorities high frequency point.Therefore, the first frequency point precedence information will not influence UE 310 after leaving railway station and entering urban district in the process of public network and business.

Optionally, which further includes step S308, and S308 can be executed after S302 or be executed after S303.

S308, after the core network control surface node device determines that the UE is first kind UE, the identity information of UE that the UE is the first kind is stored in the corresponding user's context of the UE by the core network control surface node device.For example, MME 320 can be in the UE Context in increase by the first indication information element.It is first kind UE that first indication information element, which is used to refer to the UE,.

Accordingly, in step S306, after high-speed rail private network/shared core network control surface node MME receives the TAU request message of UE transmission, the high-speed rail private network/shared core network control surface node MME also obtains the user's context of the UE to former public network/shared core network control surface node (MME) where the UE.When in the user's context including above-mentioned first indication information element, high-speed rail private network/shared core network control surface node MME just receives the access that the TAU that the UE is initiated requested and allowed the UE.When not including above-mentioned first indication information element in the user's context, high-speed rail private network/shared core network control surface node MME refuses the access request of such UE, and sends TAU reject message to such UE.

Therefore, public network/shared MME is that first kind UE preservation identity information e.g. increases corresponding indication information element in user's context.And enter the non-first kind UE of high-speed rail private network for misconnection, since corresponding first indication information element being not present in user's context, high-speed rail private network/shared core network control surface node MME refuses the access of such UE.It is thus also avoided that non-first kind UE accesses the high-speed rail private network in non-railway station region (orbital region) and occupies private network resource, to further improve the user experience of first kind UE.

Optionally, which further includes step S309, and the sequence for executing S308 and S309 does not limit herein.

S309, if it is first kind UE that the core network control surface node device, which according to the former mobile management regional code determines the UE not, the identity information of UE that the UE is not the first kind is stored in the corresponding user's context of the UE by the core network control surface node device.For example, MME 320 can increase by the second indication information element in the context of the UE.It is first kind UE that second indication information element, which is used to refer to the UE not,.

Accordingly, in step S306, after high-speed rail private network/shared core network control surface node MME receives the TAU request message of UE transmission, the high-speed rail private network/shared core network control surface node MME also obtains the user's context of the UE to former public network/shared core network control surface node (MME) where the UE.When in the user's context comprising to be used to indicate the UE be the first indication information element of the first kind UE when, high-speed rail private network/shared core network control surface node MME just receives the access that the TAU that the UE is initiated requested and allowed the UE.When in the user's context comprising to be used to indicate the UE not be the second indication information element of the first kind UE when, High-speed rail private network/shared core network control surface node MME refuses the access request of such UE, and sends TAU reject message to such UE.

Similarly, since public network/shared MME is also the non-first kind UE preservation identity information that misconnection enters high-speed rail private network, high-speed rail private network/shared core network control surface node MME can refuse the access of such UE accordingly.It is thus also avoided that high-speed rail private network described in non-first kind UE access and occupy private network resource, to further improve the user experience of first kind UE.

Fig. 3 B show the signaling interaction diagram of communication means according to an embodiment of the invention.Method under Fig. 3 B scene is also realized by UE 310, MME 320 and public network eNodeB 330 interaction.

S401, UE 310 accesses public network because of abnormal cause.

S402, MME 320 identifies that UE 310 is first kind UE.How MME 320 identifies that UE310 is the description that first kind UE can refer to step S302, and details are not described herein.

After S403, MME 320 identifies that UE 310 is first kind UE, instruction information is sent to public network base station eNodeB 330, so as to which UE 310 is redirected to the first communication network after the public network base station eNodeB 330 receives instruction information.

Optionally, S403 may particularly include:

Core network control surface node device MME 320 sends downlink NAS direct-sending message to the public network base station eNodeB 330, and the downlink NAS direct-sending message carries the instruction information.If the MME 320 receives the mobile management area update request message of the transmission of UE 310 (such as, TAU request message), it can also include following any in the downlink NAS direct-sending message: mobile management area update received message or mobile management area update refuse information.How MME 320, which provides instruction information to public network base station eNodeB 330 by downlink NAS direct-sending message, can refer to the description in S303, and details are not described herein.

Alternatively, it is optional, for LTE network, S303 can include:
