Concrete, described base station controls whether user allows to access described Emergency Communications Network, including:

By the way of broadcast, notify that the user allowing access into Emergency Communications Network accesses, it is achieved the most square Just.

Concrete, described base station is by the described user allowing to access described Emergency Communications Network of broadcast instruction Access, including:

Mode three: the permission described emergency communication net of access is set by arranging the access of the PLMN of correspondence The business that the user of network and/or permission are initiated in described Emergency Communications Network.

By above-mentioned three kinds of modes, few to the amendment of existing communication protocol, versatility is high, utilizes follow-up Use.

Owing to the network state of Emergency Communications Network is to change in the processing procedure along with business, In order to realize the accurate management to Emergency Communications Network, described base station is detecting the net of Emergency Communications Network After network ability information and/or network load information and/or Access Control operation information change, according to sending out The capability information of the Emergency Communications Network after changing and/or network load information and/or Access Control Operation information, controls whether user allows to access described Emergency Communications Network.

As seen from the above, obtaining network state information on above-mentioned opportunity, information is accurate.

Described base station receives the connection establishment request that terminal sends, and the request of wherein said connection establishment includes end The type of the business that the type of end and/or described terminal are initiated；

Concrete, base station can effectively control terminal by the way and access Emergency Communications Network.

Optionally, described method also includes:

Below the method flow of end side is illustrated:

The broadcast that terminal sends by monitoring base station indicates；

Concrete, terminal obtains Access Control information by broadcast mode, it is achieved simple and convenient.

Terminal can determine whether to initiate connection establishment request according to the information of the base station obtained, it is achieved corresponding The access-in management of anxious communication network, reaches to manage the purpose of Emergency Communications Network.

The option that IE in being asked by connection establishment is arranged transmits above-mentioned information, it is achieved simple and right Protocol modification is few, highly versatile.

Optionally, described method also includes:

With two application examples, said method is described further below:

Below embodiment can apply to EUTRAN (Evolved Universal Terrestrial Radio Access Network, the Universal Terrestrial wireless access network of evolution), and other networks of subsequent derivation. In EUTRAN network, that mobile management entity refers to is exactly MME, and base station refers to eNode. If being applied to other similar network of subsequent derivation, then mobile management entity has referred to mobile pipe Reason function, it is achieved the functional unit similar for MME with EUTRAN network of access control function, and Base station is to achieve the wireless side network element that terminal accesses.

The Emergency Communications Network that Fig. 4 provides for the present invention set up during the flow process of network settings Access Control Figure.This embodiment may be used for the network in Emergency Communications Network and detects that backbone network is already off, meeting Available Emergency Communications Network, after Emergency Communications Network being detected, meeting is detected according to the configuration of management system Set up Emergency Communications Network.During the foundation of Emergency Communications Network, base station and core net are mutual, really Allow before settled to access user and business.User can also detect and be directly connected instability with backbone network, The signaling that can only provide limited connects, thus reconfigures network, to form Emergency Communications Network.

Suddenly at the initial stage interrupted in view of network, there may be a large amount of public safety terminal needs access network, Therefore in this flow process, suggestion only allows the terminal of public safety to access.If allowing the urgent of other-end The information of service access mobile management unit notice base station is arranged, and the setting of base station broadcast information and figure 5 are similar to.

Step 400, network or base station testing mechanism detect that base station disconnects with the connection of original backbone network, Or it is merely capable of providing limited connection, needs to form Emergency Communications Network.

Step 401, after the management system of base station completes base station configuration, detecting can in Emergency Communications Network Mobile management entity, be sent to S1 set up request.

Step 402, the S1 that mobile management entity returns to base station sets up response, wherein carries emergency communication The type of service that network can provide, and or the capacity information of mobile management entity and/or Access Control operation Information.

Due to Emergency Communications Network primarily to public safety user service, therefore providing COS When can be realized by several ways: the type of service that clear and definite instruction network can provide, such as Only service for public safety user, for concrete types such as public safety user and emergent service users services； When not carrying any kind of, it is believed that only service for public safety user, when providing other business The when of type, particularly point out the kind that type of service can be provided, such as urgency traffic etc..

In addition the capacity information of mobile management entity can also implicit expression show the receptible clothes of current network Service type, such as certain by managing default threshold value: when reaching a certain capacity threshold when, Only service for public safety user；When reaching another capacity threshold when, for public safety user with tight Anxious service-user service.

When public safety uses specific PLMN to access, access only allowing public safety user When, the most only comprise the PLMN of public safety.Public safety user and emergent service users is allowed to connect The when of entering, can comprise the special PLMN of public safety and mobile management entity can support PLMN。

Mobile management unit can need the concrete of Access Control by Access Control operation information instruction base station Operation, such as, can be accomplished in that the operation of Access Control is only to allow public safety user Access, or be the concrete type such as public safety user and emergent service users service simultaneously, or with Time be the called service service of public safety user and emergent service users service and domestic consumer, or with Time be that the operator such as signaling access of public safety user and emergent service users service and domestic consumer is actual The mode of operation needed.

Step 403, base station according to the instruction information in step 402 and or self information on load, determine How specific user is indicated to access by broadcast.Such as when being designated as public safety in step 402 User and emergent service users service, but due to the Load reason of base station self, base station can also be complete Public safety user and emergent service users is allowed to access according to the instruction of step 402, it is also possible to according to certainly The load of body only allows public safety user to access

Step 404, after base station determines the grade of Access Control, can pass through, but be not limited to following manner Realize Access Control:

1. base station is in broadcast, is arranged by a single IE and the most only allows public safety to use Family is accessed.When being set to only permit public safety user and accessing, do not allow other any not common safety User initiates any access.Otherwise, it is allowed to outside public safety user accesses, it is also possible to wide by other The cell broadcasting message further determines whether to initiate urgency traffic or high-priority users business etc. Deng.Arranging that base station is concrete can be in the following way: arranges a new IE, simply public for allowing Secured user accesses, and simultaneously by indicating the broadcast flag of other business, such as urgency traffic, is set to Do not allow, and the indicating bit of other high priorities is both configured to not allow.So not common secured user Owing to newly-increased indicating bit cannot be read, or in the case of reading, can find it oneself is not public safety User, and other business read or owing to not allowing, or just do not mate owing to priority is arranged Will not access.

2. the IE during base station utilizes existing broadcast is in instruction.Access when only allowing public safety user Time, urgency traffic allow mark be set to forbid.Access control (Access Control) is utilized to realize Public safety user is only allowed to access.The access control value that for example, public safety user setup is new, Such as AC==16 (value that i.e. prior art is not provided with), the terminal of public safety user need by This set represents it oneself is public safety user, and base station arranges and allows the user of this value to access simultaneously. Or require that public safety user by AC set of all mark high priorities or uses special group Conjunction mode (this mode needs there is special setting means when of operator configurating terminal AC), from And representing it oneself is a public safety user, base station arranges and allows the user of all set to access simultaneously.

When 3. specific PLMN can be used to access for public safety, if base station only allows Public safety user accesses, the most only the specific PLMN of broadcast public safety institute.Otherwise also need to broadcast it He is PLMN, and can be next by arranging urgency traffic permission mark further for not common secured user Further discriminate between user, be set to only urgency traffic and initiate or high-priority users access.

When being set in this way only allow public safety user to access, other users cannot access Network originated traffic, but if other the user discover that the most not available community still may reside within In the community of Emergency Communications Network.Emergency Communications Network now allows and/or network capabilities permission at load Under conditions of, can perform to broadcast ETWS/PWS business, contingent danger is carried out early warning, And these not common secured user can also obtain these information by the way of listening broadcast.

Step 405, terminal is mated with the Access Control flag oneself arranged according to broadcast message, determines Whether initiation is asked, access network.

Terminal can carry in follow-up initiation connection request message whether the type of oneself (is that public safety is used Family) and or oneself type of service (urgency traffic or general service etc.).Base station can be according to these Information and oneself Access Control grade are done and are mated, and the connection that can refuse terminal in absence of such a match please Ask.

Terminal can show the type (whether being public safety user) of oneself by newly-increased IE, it is also possible to Method according to step 404 description shows the type of oneself by the combination of existing IE.

Step 406, performs the residue flow process of access network.This flow process has been described above in the prior art, Repeat no more in the present invention.

As seen from the above, during Emergency Communications Network is set up, user is accessed Emergency Communications Network It is controlled, on the one hand ensure that the safety of Emergency Communications Network, on the other hand take full advantage of emergent The resource of communication network.

Fig. 5 changes the flow chart of Network access control for the Emergency Communications Network that the present invention provides after setting up. After this embodiment may be used for Emergency Communications Network foundation, ability or the information on load of network there occurs The when of change, network can notify that base station changes the strategy of Access Control, thus allows more user Access, or reduce specific user's access.If network capabilities there occurs change, using the teaching of the invention it is possible to provide business Ability there occurs change, such as from having the server of urgency traffic to not having, it is necessary to notifies to base station, Vice versa.Or load there occurs change, such as access user too much, cause network load relatively big, Could be arranged to only allow public safety user to access.Or the less network load of access customer number is relatively low, Could be arranged to allow public safety user and emergent service users to access.

The change of aforementioned capabilities change or information on load can be configured by background management system, as Fruit is complete Background control, then need not perform step 501～502.

Step 500, the load of Emergency Communications Network there occurs change, or Emergency Communications Network itself Ability there occurs change.

Step 501, mobile management entity notice base station network capacity variation and or load variations.

Advice method it may be that but be not limited to: by configuration update message notify base station, now step 501 and step 502 be required for perform；Started by premature beats or premature beats terminate to notify, Now need not perform step 502；Notified by newly-increased message, new information can be set as required It is set to need response or need not the message of response, needs if necessary to perform step 502.

No matter use that mode, be required for comprising within the message and carry Emergency Communications Network and can provide Type of service, and or the capacity information of mobile management entity and/or Access Control operation information.

Can be realized by several ways when that this message providing COS: clear and definite instruction network The type of service that can provide, the most only for public safety user service, for public safety user and urgent The concrete types such as service-user service；When not carrying any kind of, it is believed that only use for public safety Family services, and when can providing other types of service when, particularly points out the kind that can provide type of service Class, such as urgency traffic etc..

When public safety uses specific PLMN to access, access only allowing public safety user When, the most only comprise the PLMN of public safety.Public safety user and emergent service users is allowed to connect The when of entering, can comprise the special PLMN of public safety and mobile management entity can support PLMN.If multiplexing configuration update message, next real by sending different PLMN the most within the message Existing above-mentioned functions.If multiplexing premature beats starts or premature beats terminates, or increase new information, Then need to increase PLMN ID in these message, and realize above-mentioned merit by arranging different values Energy.

Step 502, base station returns response message after receiving instruction.

Step 503, base station according to the instruction information in step 501 and or self information on load, determine How specific user is indicated to access by broadcast.Such as when being designated as public safety in step 501 User and emergent service users service, but due to the Load reason of base station self, base station can also be complete Public safety user and emergent service users is allowed to access according to the instruction of step 501, it is also possible to according to certainly The load of body only allows public safety user to access.

Step 504, after base station determines the grade of Access Control, can pass through, but be not limited to following manner Realize Access Control:

1. base station is in broadcast, is arranged by a single IE and the most only allows public safety to use Family is accessed.When being set to only permit public safety user and accessing, do not allow other any not common safety User initiates any access.Otherwise, it is allowed to outside public safety user accesses, it is also possible to wide by other The cell broadcasting message further determines whether to initiate urgency traffic or high-priority users business etc. Deng.Can also access if provided as urgency traffic, then this IE needs to be expressed as non-to be only limitted to public peace Full user accesses.The most whether allow to carry out urgency traffic, in addition it is also necessary to determine whether that urgency traffic allows Flag bit.Arranging of emergency traffic flag position can perform according to prior art.The concrete setting in base station can With in the following way: arrange a new IE, simply for allowing public safety user to access, will simultaneously Indicate the broadcast flag of other business, such as urgency traffic, be set to not allow, and other Gao You The indicating bit of first level is both configured to not allow.So not common secured user is owing to cannot read newly-increased finger Show position, or in the case of reading, can find it oneself is not public safety user, and other read Business or owing to not allowing, or do not mate would not access owing to priority is arranged.

2. the IE during base station utilizes existing broadcast is in instruction.Access when only allowing public safety user Time, urgency traffic allow mark be set to forbid.Access control (Access Control) is utilized to realize Public safety user is only allowed to access.The access control value that for example, public safety user setup is new, Such as AC==16 (value that i.e. prior art is not provided with), the terminal of public safety user need by This set represents it oneself is public safety user, and base station arranges and allows the user of this value to access simultaneously. Or require that public safety user by AC set of all mark high priorities or uses special group Conjunction mode (this mode needs there is special setting means when of operator configurating terminal AC), from And representing it oneself is a public safety user, base station arranges and allows the user of all set to access simultaneously.If It is positioned to allow for public safety.And now terminal can be by configuring the AC flag bit of oneself, calcaneus rete network Mate, thus determine whether oneself is allowed to the user of access network.

When being set in this way only allow public safety user to access, although can be with other users Access network cannot initiate business, but if other the user discover that still may be used in the most not available community To reside in the community of Emergency Communications Network.Emergency Communications Network now allows and/or network at load Under conditions of ability allows, can perform to broadcast ETWS/PWS business, contingent danger is entered Row early warning, and these not common secured user can also obtain these information by the way of listening broadcast.

Step 505, terminal is mated with the Access Control flag oneself arranged according to broadcast message, determines Whether initiation is asked, access network.

Terminal can show the type (whether being public safety user) of oneself by newly-increased IE, it is also possible to Method according to step 504 description shows the type of oneself by the combination of existing IE.

Step 506, performs the residue flow process of access network.This flow process has been described above in the prior art, Repeat no more in the present invention.

As seen from the above, the network condition at Emergency Communications Network occurs after an action of the bowels, by again to user Carry out Access Control, on the one hand ensure that the safety of Emergency Communications Network, on the other hand take full advantage of The resource of Emergency Communications Network.
