For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.

Fig. 1 is the flow chart that the present invention selects the embodiment of the method one of PLMN access network, as it is shown in figure 1, the method includes:

The quantity of the UE accessed on step 101, home service device statistics the oneth PLMN.

UE in various embodiments of the present invention can be M2M terminal.Home service equipment in the embodiment of the present invention can be HLR or HSS;In following embodiment, illustrate as a example by HSS;Home service equipment is the flow process that flow process during HLR may refer to that home service equipment is HSS.

Each mobile management unit (MobilityManagementEntity, referred to as: mark MME) all includes PLMNID information;When UE is registered to MME, MME can pass through authentication request message or location update message, the mark (including PLMNID information) of this MME and the IMSI (InternationalMobileSubscriberIdentificationNumber, international mobile subscriber identity) of this UE are sent to HSS;Wherein, corresponding for this MME PLMNID is the PLMNID of the PLMN that this UE accesses.

After HSS receives PLMNID and IMSI that MME sends, the quantity of the UE that PLMN that will be corresponding to this PLMNID accesses adds 1.Such as: MME1 correspondence PLMNID1, PLMNID1 correspondence PLMN1, UE1 correspondence IMSI1, UE2 correspondence IMSI2;When UE1 is registered to MME1, MME1 sends PLMNID1 and IMSI1 to HSS, and now the quantity of the UE accessed on PLMN1 is added 1 by HSS, afterwards, UE2 is also registered to MME1, MME1 and sends PLMNID1 and IMSI2 to HSS, and now the quantity of the UE accessed on PLMN1 is added 1 by HSS again.

When HSS receives registration message (purge message), the quantity of the UE that the PLMN that HSS can be corresponding to this PLMNID accesses subtracts 1.During multiple UE access PLMN and/or exit PLMN, HSS can add up the quantity of the UE accessed on each PLMN.A PLMN therein is the PLMN that current UE accesses.

Step 102, home service equipment, according to the quantity of UE accessed on a PLMN and presetting rule, send a notification message, to notify the state of PLMN or available PLMN to UE.

HSS can be according to presetting rule, when network at arbitrary PLMN is unsatisfactory for requiring, to UE or MTC platform (MTCservice, machinetypecommunicationservice, machine type communication platform) send a notification message, access from this PLMN with restriction UE, and make UE select other PLMN to access.Wherein, the notification message that home service equipment sends, can be the first notification message of sending to UE of home service equipment, it is also possible to the second notification message sent to MTC platform for home service equipment.

This presetting rule may include that the population size of the UE accessed according to a certain PLMN decides whether to limit and accesses this PLMN;Or, according to the population size of the UE that a certain PLMN accesses, and the network state information of this PLMN decides whether to limit to access this PLMN the most extremely.Concrete, HSS when the quantity of the UE that arbitrary PLMN accesses is more than a threshold value, can include the notification message of currently available PLMN list to UE transmission for the notification message or transmission limiting this PLMN of access;Or, HSS can be when the quantity of the UE that arbitrary PLMN accesses be more than a threshold value, the quantity of the UE accessed by this PLMN is sent to MTC platform, and then MTC platform includes the notification message of currently available PLMN list to UE transmission for the notification message or transmission limiting this PLMN of access;Or, HSS can be when the quantity of the UE that arbitrary PLMN accesses be more than a threshold value, the quantity of UE and the network state information of this PLMN that are accessed by this PLMN are sent to MTC platform, then MTC platform is when the quantity of the UE that this PLMN accesses is more than the network state information exception of this threshold value and this PLMN, includes the notification message of currently available PLMN list for the notification message or transmission limiting this PLMN of access to UE transmission;Or, HSS can be more than a threshold value in the quantity of the UE that arbitrary PLMN accesses, and during the network state information exception of this PLMN, the quantity of UE accessed by this PLMN and the network state information of this PLMN are sent to MTC platform, and then MTC platform includes the notification message of currently available PLMN list to UE transmission for the notification message or transmission limiting this PLMN of access.

Wherein, state or the available PLMN of the oneth PLMN are notified to UE by HSS or MTC platform, refer to: HSS or MTC platform sends and includes the state of a PLMN or the information broadcast notice messages of available PLMN, all notices being able to receive that the UE of this broadcast notice messages just can receive HSS or MTC platform.

When UE is informed to limit and accesses a certain PLMN, UE can select other available PLMN to access.In the present embodiment, the threshold value in above-mentioned presetting rule, can determine according to practical situation;The quantity of the network of each PLMN UE for accessing on this PLMN has certain requirement, to meet the demand of network normal operation.

The embodiment of the present invention, the quantity of the UE that home service device statistics the oneth PLMN accesses;Then, home service equipment, according to the quantity of UE accessed on a PLMN and presetting rule, sends a notification message to UE or MTC platform;The quantity making the UE accessed on a PLMN exceedes threshold value, or when the quantity of the UE accessed on a PLMN exceedes the network state information exception of threshold value and this PLMN, home service equipment or MTC platform can notify that limiting UE accesses this PLMN, and make UE that other PLMN can be selected to access;Thus can be implemented in when network problem occurs in PLMN or during in order to meet the requirement of current PLMN network, can effectively control user from available PLMN access network.

In the scheme that the embodiment of the present invention provides, can judge whether to limit by HSS and access PLMN, and when needs limit and access PLMN, HSS directly send a notification message to UE;Can also judge whether to limit by MTC platform and access PLMN, and when needs limit and access PLMN, MTC platform send a notification message to UE.The embodiment of the present invention is specifically described by a point situation below.

Fig. 2 is the flow chart that the present invention selects the embodiment of the method two of PLMN access network, as in figure 2 it is shown, the method includes:

Step 201, UE1 are registered to MME1 by base station (eNB).

The application scenarios of the present embodiment is: home service equipment judges whether to limit access PLMN, and when needs limit and access PLMN, home service equipment directly sends a notification message to UE.In following embodiment, home service equipment illustrates as a example by HSS.

Step 202, MME1 send authentication request message or location update message to HSS;Wherein, authentication request message or location update message carry the IMSI1 corresponding for PLMNID1 with UE1 of MME1.

Wherein, the PLMNID1 of MME1, it is the PLMNID1 of the PLMN (PLMN1) that this UE1 is accessed.

The quantity of the UE accessed on step 203, HSS statistics PLMN1;When the quantity of the UE accessed on PLMN1 is more than the first threshold value, perform step 204.

The description in the quantity embodiment shown in Figure 1 step 101 of UE is accessed on HSS statistics PLMN1.After HSS receives PLMNID1 and IMSI1 that MME1 sends, the quantity of the UE that PLMN1 accesses is added 1.

Step 204, HSS send the first notification message including the first announcement information to UE, access PLMN1 to limit.

Wherein, the UE in this step is not defined by the present embodiment, and HSS sends the first notification message, it is possible to the UE receiving this notification message can receive this notification message, such as UE1 and UE2 shown in figure.

Wherein, this first announcement information may include that to limit and accesses the information of PLMN1 and/or currently available PLMN list;That is, this first announcement information is used for limiting UE and accesses this PLMN1, or this first announcement information is for informing PLMN list currently available for UE, or, this first announcement information is informed to UE for the information that currently available PLMN list and restriction access PLMN1 simultaneously, make UE that other available PLMN can be selected to access, thus realize M2M business.It should be noted that when the first announcement information includes limiting the information accessing PLMN1, or, when the first announcement information includes currently available PLMN list, this first announcement information all can limit UE and access this PLMN1;During it is to say, only include currently available PLMN list in the first announcement information, not comprising PLMN1 in this currently available PLMN list, now UE obtains available PLMN access from this list, and no longer accesses from PLMN1.

This first notification message can be cell broadcast messages.Cell broadcast messages can include CBC (CellBroadcastCentre, CBC) message and ACB (AccessClassBaring, access grade is forbidden) message.Concrete, this first notification message can be CBC message or ACB message, say, that the first announcement information can be sent to UE by CBC message or ACB message by HSS, is specifically introduced both notification messages below.

A, the first notification message are CBC message, i.e. use the mode of CBS (CellBroadcastService, cell broadcaste service) to send a notification message.

HSS sends the notification message comprising the first announcement information to CBC, and then CBC sends the CBC message comprising the first announcement information to MME;This first announcement information is notified to corresponding eNB by MME again by CBC message;Then by broadcast, this first announcement information is broadcast to UE by eNB.

Wherein, this first announcement information may include that limit access PLMN1 information, and/or, current UE can PLMN list.

B, the first notification message are ACB message.

HSS sends the ACB message comprising the first announcement information to MME1;This first announcement information is notified to corresponding eNB by MME again by ACB message;Then by broadcast, this first announcement information is broadcast to UE by eNB.

Wherein, this first announcement information may include that and limits the information accessing PLMN1.

It should be noted that in various embodiments of the present invention, after HSS sends cell broadcast messages, all UE being able to receive that this message just can receive this message.

In another embodiment, can in HSS configure-reject UE access strategy so that HSS when a certain PLMN is limited access, refusal accessing this PLMN other UE send request, thus on the basis of above-described embodiment, the present embodiment can also include:

Step 205, when the quantity of the UE accessed on PLMN1 is more than the first threshold value, HSS sends the message that refusal accesses, and the UE being currently registered to PLMN1 with refusal is registered to PLMN1.

When the quantity of the UE accessed on PLMN1 is more than the first threshold value, if there being UE to access this PLMN1 again, then PLMN1 may will cause network congestion or be unsatisfactory for the requirement of this PLMN1 network because of the increase of UE number-of-registration because of the increase of UE number-of-registration, thus, HSS can refuse current UE in authentication request response or position updating request response and be linked into network from this PLMN1, such as when UE1 or UE2 is the UE being currently accessed, send, to UE, the message that refusal accesses.

Above steps is to limit the process that UE accesses from PLMN1, but, after the UE quantity accessed on PLMN is recovered normally, it is also possible to this PLMN of UE is currently available for notice so that UE can be from this PLMN access network;Thus, on the basis of above-described embodiment, after step 205, the present embodiment can also comprise the following steps:

Step 206, when the quantity of the UE accessed on PLMN1 is less than or equal to the first threshold value, HSS sends to UE and comprises the 4th notification message of the second announcement information.

Wherein, the 4th notification message that HSS sends, all UE being able to receive that this notification message can receive, such as UE1 and UE2 shown in figure.

Wherein, this second announcement information may include that to cancel limiting and accesses the information of PLMN1 and/or currently available PLMN list;That is, this second notification message is used for informing that UE currently can access this PLMN1, or this second announcement information is for informing PLMN list currently available for UE, or, this second announcement information is for by currently available PLMN list and currently can access PLMN1 and inform to UE simultaneously, make UE that this PLMN1 can be selected to access, thus realize M2M business.

The quantity of the UE of the upper access of PLMN1 is change, when the quantity of the UE accessed on PLMN1 is less than or equal to the first threshold value, other UE can be allowed to be linked into PLMN1;Thus, when HSS count on PLMN1 access UE quantity less than or equal to the first threshold value time, HSS judge whether again to UE be transmitted across limit access PLMN1 the first notification message, if being transmitted across, then HSS by message informing currently available for PLMN1 to UE.

Wherein, the 4th notification message can be identical with the type of the first notification message described in step 204.When the 4th notification message is CBC message, this second announcement information may include that to cancel and limits the information accessing PLMN1, is used for indicating UE can be linked into network from PLMN1;And/or, current UE can PLMN list.When the 4th notification message is ACB message, this second announcement information may include that to cancel and limits the information accessing PLMN1.

The embodiment of the present invention, the quantity of the UE that HSS statistics the oneth PLMN accesses;Then, when the quantity of the UE that HSS accesses on a PLMN exceedes threshold value, notice this PLMN of UE limits and accesses so that UE can select other PLMN to access;Thus can be implemented in when network problem occurs in PLMN or during in order to meet the requirement of current PLMN network, can effectively control user from available PLMN access network, thus realize M2M business.

Fig. 3 is the flow chart of the embodiment of the method three of PLMN access network of the present invention, as it is shown on figure 3, the method includes:

Step 301, UE1 are registered to MME1 by eNB.
