Description

  This application is filed with Chinese Patent Application No. 200910146661., entitled “Access Control Method, Apparatus and System” filed with the Chinese Patent Office on June 12, 2009. The priority of X is claimed and this application is incorporated herein by reference in its entirety.

  The present invention relates to the field of communication technology, and more particularly to an access control method, apparatus, and system.

  In a communication system, when a user equipment (UE: user equipment) sends an access request to the network, the network sometimes determines the access request to determine whether to allow access and how the UE enters the network. It is necessary to determine whether to access. The existing access control method in the prior art is as follows.

  1. Dynamic soft admission control (DSAC: Dynamic soft admission control)

  DSAC is a special access control method used when a disaster occurs in a universal mobile communication system (UMTS).

  Packet switched (PS) services use network resources at a higher rate than circuit switched (CS: circuit switched) services. Therefore, when the network is congested as a result of a disaster, the PS domain service is given priority when the network is smoothed. DSAC is a domain-based access control method. For example, DSAC avoids intermittent service in the PS domain by restricting CS calls. When a disaster occurs, the system sends control information about various domains to the UE via system messages. After the UE has read the system message, if the UE detects domain-based control information, the UE applies such information to perform access control, and if the UE does not detect domain-based control information, the UE The access control is performed by applying normal access control information.

  2. Access control in the access hierarchy (AS: access hierarchy) within the long term evolution (LTE: long term evolution) system

  Currently, service access restrictions imposed on the AS of the LTE system include access class restrictions on the UE (ACB: access class restrictions) and access control on the evolved NodeB (eNB).

  The ACB process includes: That is, the radio resource control (RRC: radio resource control) layer of the UE performs restriction before access in the RRC layer according to the access type transmitted in the access request after receiving the access request from the upper layer, If it is determined that access is allowed after the determination, the UE adds an access type to the message and sends the message to the eNB, and the eNB performs further access control according to the access type.

  Currently, five access types are applied to UE-side ACB and eNB-side access control. The five access types are emergency call (emergency), highest priority user (high Priority Access), mobile station arrival (mt-Access), mobile station transmission signal transmission (mo-Signaling), and mobile station transmission data (mo-Data). .

  In many cases, access control based on service type is required. For example, when a large disaster occurs, the operator provides a disaster message board service to all users. Many users can simultaneously read and write the disaster message board via a mobile phone to obtain or provide information on personal safety. Therefore, this service requires a very high utilization of system bandwidth. However, when a major disaster occurs, a person's instinctive reaction is to make a phone call. Such voice services, which increase suddenly, consume a lot of bandwidth and severely affect other services such as the disaster message board service, disaster information broadcast service and data service described above. In this case, we introduce a specific restriction mechanism that prioritizes data services with high bandwidth utilization by distinguishing bandwidth-consuming real-time services (such as voice services) from data services with high bandwidth utilization (such as disaster information broadcasts). There is a need to.

  However, in the prior art, DSAC provides only domain-based access control methods. The five access types provided for access control in the AS in the LTE system do not include a service type, and it is impossible to perform access control based on the service type.

  Embodiments of the present invention provide an access control method, apparatus, and system.

  One embodiment of the invention includes determining whether a UE needs to perform access control for a particular service and sending a system broadcast message to the UE, the system broadcast message being specified by the UE. Provided is an access control method for transmitting service-specific access control information when it is necessary to perform access control for other services.

  Another embodiment of the present invention is to receive a system broadcast message transmitting service-specific access control information by a UE, and to perform access control for a specific service by the UE according to the service-specific access control information.

  As can be understood from the foregoing technical solutions, different service types correspond to different service-specific access control information, so that the UE can follow the service-specific access control information that meets the user's request. Access control can be performed for access requests specific to various services.

Apparently, the drawings and detailed description are merely representative of specific embodiments of the invention, which are exemplary in nature and not exhaustive. All other embodiments that can be derived by those skilled in the art from the embodiments shown here without creative efforts shall fall within the scope of the invention.

  Generally, when a disaster such as an earthquake or a tsunami occurs, access control based on services is required. In such a situation, the user makes more calls than usual and sends more messages than usual. With more other services consuming resources, network resources are very pressing in the event of a disaster. Therefore, it is necessary to perform access control based on the service so that a service having a high bandwidth utilization rate and a service having a high priority obtain resources first. After determining the need for service-based access control according to received instructions or other conditions, the network sends a system wideband message carrying service-specific access control information. Note that the expression “service specific” or “specific service” here indicates that service-based access control is access control specific to various services. In contrast, existing normal access control is not based on services but based on normal sorting methods. Thus, a particular service may here be a specified service, a dedicated service, or a special service, or any other representation that reflects an access control method, a service based. Such various expressions are not to be construed as limiting the invention.

  Embodiments of the present invention provide an access control method, apparatus, and system. In service type-based access control methods, when a network congestion, disaster or sudden surge of services occurs or is about to occur, the network is service specific to the UE according to various pre-configured service types. Send access control information. The UE performs access control for access requests specific to various services according to service-specific access control information. In this way, access control is performed for access requests according to the service type.

  Specifically, the network determines whether the UE needs to perform access control for a specific service, and then sends a system broadcast message to the UE according to the determination result. If the UE needs to perform access control for a specific service, the system broadcast message carries service-specific access control information, and if the UE does not need to perform access control for a specific service, the system The broadcast message carries conventional access control information, that is, access control information that is not specific to the service.

  When the UE receives a system broadcast message, if the system broadcast message carries service-specific access control information, the UE performs access control for a particular service according to the service-specific access control information, and the system broadcast message Transmits conventional access control information, that is, access control information that is not service-specific, the UE performs access control that is not service-specific according to the conventional access control information, for example, an access control method implemented in the prior art. Apply.

  Possible service types within this embodiment include the following: voice (MMTEL voice) service, video (MMTEL video) service, data service, short message service (SMS), multimedia service, voice over internet protocol ( There are any one or combination of VoIP) services and other services. The various service types are further classified into mobile station originating service types and mobile station terminating service types. The above classification method is only an example. In practice, service types can be further classified according to actual conditions. For example, with respect to service-specific access control in the system, specific service types may include mobile originating voice service, mobile terminating voice service, mobile originating video service, and mobile terminating video service. The service-specific access control information may be access control information specific to any one of these four service types. With respect to conventional access control (access control not specific to a service), service types can include mobile station originating services and mobile station terminating services. Therefore, the conventional access control information (access control information not specific to the service) may be access control information specific to the mobile station originating service or access control information specific to the mobile terminal terminating service, and is specific to the service. Not something.

  The service-specific access control information may include any one or combination of the following: whether the service is allowed access, the probability of granting access, or the priority of access, of course, service-specific The access control information may include other related information.

  In the access control method presented in this embodiment, different service types correspond to different service-specific access control information, so that the UE can change according to the service-specific access control information that satisfies the user's request. Access control can be performed for access requests specific to other services.

  Regarding the mobile station originating service, FIG. 1 is a flowchart of an access control method according to the first embodiment of the present invention. The method includes the following steps.

  101. Send a system broadcast message. The system broadcast message transmits access control information based on the mobile station transmission service, and the access control information includes information specific to each mobile station transmission service.

  When a disaster occurs or a sudden surge in service occurs, the network determines that it is necessary to perform access control based on the service and sends a system broadcast message. The system broadcast message carries access control information specific to various mobile station originating services. For example, the message carries accessBarringForMO-voice, which is information specific to the mobile originating MMTEL video service, the message carries accessBarringForMO-video, which is information specific to the mobile originating MMTEL video service, and the message AccessBarringForMO-other, which is information specific to the mobile station transmission service.

  102. The UE receives a system broadcast message.

  Specifically, the RRC layer of the UE receives a system broadcast message.

  103. The UE acquires access control information based on the mobile station originating service from the system broadcast message.

  104. The UE performs access control for an access request specific to each mobile station transmission service according to the access control information based on the mobile station transmission service.

  Specifically, the RRC layer of the UE applies control information to perform access control for a mobile station-originated service access request that is informally approved by the non-access layer (NAS).

  Further, the UE uses the access control information based on the mobile station originating service preferentially, and when there is no access control information based on the mobile station originated service, the access control information not specific to the service (existing accessBarring information, etc.) May be used.

  Regarding the mobile terminal incoming service, FIG. 2 is a flowchart of an access control method according to the second embodiment of the present invention. The method includes the following steps.

  201. Send a system broadcast message. The system broadcast message transmits access control information based on the mobile station incoming service, and the access control information includes information specific to each mobile station incoming service.

  In the event of a disaster or a sudden surge in service, the network determines that access control based on the service is necessary and provides access control information specific to various mobile terminating services. Send a system broadcast message for transmission. For example, the message carries accessBarringForMO-voice, which is information specific to mobile originating MMTEL voice service, the message carries accessBarringForMO-video, information specific to mobile terminating MMTEL video service, and the message is miscellaneous The accessBarringForMO-other, which is information specific to the mobile terminal incoming service, is transmitted.

  202. The UE receives a system broadcast message.

  Specifically, the RRC layer of the UE receives a system broadcast message.

  203. The UE acquires access control information based on the mobile station termination service from the system broadcast message.

  204. The UE performs access control according to access control information based on the mobile station incoming service for an access request specific to each mobile station incoming service.

  Specifically, the RRC layer of the UE applies control information to perform access control for a mobile station incoming service access request sent by the NAS.

  Furthermore, the UE uses the access control information based on the mobile station termination service preferentially, and if there is no access control information based on the mobile station termination service, the access control information not specific to the service (existing accessBarringInformation etc. ) May be used.

  According to the first embodiment and the second embodiment of the access control method, the UE can control the access in the earliest step of setting up the connection to prevent subsequent network node congestion without delay, and independently. Access control policies are set for various service types, resulting in improved bandwidth utilization.

  Embodiments of the present invention provide multiple methods for starting or stopping service-based access control.

  Specifically, if it is determined that service-based access control can be initiated, the network continues to send a system broadcast message that transmits service-specific access control information and transmits service-specific access control information After receiving the system broadcast message, the UE starts to perform service-based access control. If it is determined that service-based access control can be stopped, the network stops sending a system broadcast message carrying service-specific access control information, and the UE can service-specific access control from the system broadcast message. If the information acquisition fails, the UE stops performing access control for various service access requests according to the service-specific access control information. When the UE needs to perform access control, the UE performs access control according to access control information not specific to the service.

  FIG. 3 is a flowchart of an access control method according to the third embodiment of the present invention. The method includes the following steps.

  301. Send a system broadcast message. The system broadcast message carries service-specific access control information or conventional access control information.

  When a disaster occurs or a sudden surge in service occurs, the network determines that it is necessary to perform access control based on the service and can stop access control based on the service. It continues to send system broadcast messages that carry service-specific access control information until it is determined.

  If the network determines that service-based access control can be stopped or is no longer needed, the network may stop sending system broadcast messages carrying service-specific access control information, and A message for transmitting conventional access control information may be further sent to the system broadcast.

  302. The UE receives a system broadcast message.

  Specifically, the RRC layer of the UE receives a system broadcast message.

  303. The UE determines whether the system broadcast message carries service-specific access control information, and if the system broadcast message carries service-specific access control information, the procedure proceeds to step 304 where the system broadcast message is serviced. If the unique access control information is not transmitted, the procedure proceeds to step 305.

  Specifically, this step is optional. For example, the UE does not make a determination independently, reads content related to access control in the system broadcast message, and executes step 304 or step 305 according to the related content.

  304. The UE acquires service-specific access control information from the system broadcast message, and performs access control for various service access requests according to the service-specific access control information.

  When the system broadcast message received by the UE carries service-specific access control information, the UE starts using the service-specific access control information to perform access control when receiving the message, Stop using access control information (not based).

  Furthermore, after this step, the UE may continue to receive system broadcast messages. When the system broadcast message is updated, the UE performs access control according to the updated system broadcast message. For example, the updated system broadcast message does not carry service-specific access control information, so the UE performs step 305.

  305. The UE performs access control using conventional access control information.

  For example, the UE stops using service-specific access control information and resumes using conventional access control information.

  Specifically, if the system broadcast message received by the UE does not transmit service-specific access control information, the UE stops using the service-specific access control information (if any) and Resume use of access control information.

  Through this embodiment, the UE knows when to start and stop using service specific access control information without requiring extra signaling.

  One embodiment of the present invention provides another method for starting and stopping the use of service-based access control. This method is as follows. If the network determines that service-based access control is required, the network sends a paging message that transmits a service-based access control indication to the UE and transmits service-specific access control information When a system broadcast message is sent and an instruction for access control based on a service is received, the UE starts reading the system broadcast message and performs access control based on the service. Thus, if the network determines that service-based access control can be stopped or is no longer needed, the network may send a paging message to the UE carrying an indication of non-service-based access control. Often, a system broadcast message for transmitting conventional access control information may be sent without sending a system broadcast message for transmitting service-specific access control information. After receiving the indication, the UE does not perform access control for various service access requests according to the service specific access control information.

  FIG. 4 is a flowchart of an access control method according to the fourth embodiment of the present invention. The method includes the following steps.

  401. Send paging message and system broadcast message to UE. The paging message transmits a service-based access control instruction, and the system broadcast message transmits service-specific access control information.

  When a disaster occurs or a sudden surge of services occurs, the network determines that access control based on the service is necessary and sends a paging message and a system broadcast message to the UE. The paging message transmits a service-based access control instruction, and the system broadcast message transmits service-specific access control information.

  402. The UE receives an access control instruction based on the service and immediately receives a system broadcast message.

  403. The UE acquires service-specific access control information from the system broadcast message, and performs access control for various service access requests according to the service-specific access control information.

  In step 402-403, upon receiving a service-based access control indication, the UE starts reading the system broadcast message immediately without waiting for the arrival of the next system broadcast message change boundary. Therefore, the UE can immediately acquire service-specific access control information in the system broadcast message, and can perform access control. Of course, as soon as the UE starts using service-specific access control information, the UE stops using the conventional access control information.

  404. If the network determines that it is reasonable to stop the service-based access control, the network sends a paging message that transmits an instruction to stop the service-based access control to the UE, and the service-specific access control. Stop sending system broadcast messages that carry information.

  Specifically, the network can send an updated paging message that transmits an instruction to stop access control based on the service, or the updated paging message indicates an instruction for access control based on the service. Do not transmit. In this way, the UE knows information about stopping service specific access control without delay. Furthermore, this indication can also be used to trigger the UE to read the updated system broadcast message immediately. For example, the network sends an updated paging message and sends an updated system broadcast message immediately or simultaneously. The updated system broadcast message includes conventional access control information. The conventional access control information here may be the same as or different from the conventional access control information previously transmitted in the system broadcast message, i.e. the conventional access control information is here updated to the conventional Access control information.

  405. Upon receiving an instruction to stop access control based on the service, the UE stops using the service-specific access control information and resumes using the conventional access control information.

  The UE may immediately read the system broadcast message and acquire the conventional access control information so as to perform access control according to the conventional access control information. The UE may read the system broadcast message when access control needs to be performed. The UE may configure default conventional access control information or may store previously obtained conventional access control information. Prior to receiving the latest access control information, the UE uses default information or stored information for access control.

  Through this embodiment, the UE may obtain access control information immediately after receiving a service-based access control indication without waiting for the arrival of the next system broadcast message change boundary. Therefore, the UE can perform access control based on the service more quickly and prevent network congestion during the standby period.

  Furthermore, embodiments of the present invention provide a method for matching the access service type value transmitted in the access request of the NAS of the UE with the access service type value used by the RRC layer, the method comprising: It is known briefly as a synchronization method.

  In the first synchronization method presented in the embodiment of the present invention, the NAS sends an access request for transmitting an access service type value to the RRC layer. The access service type value includes a type of mobile originated access based on service and / or a type of mobile incoming access based on service. If the RRC layer of the UE does not perform access control for various service access requests according to the service-specific access control information, the UE RRC layer may request access according to the mobile origination access type of the call or the mobile termination access type. Access control for

  When the RRC layer of the UE performs access control for various service access requests according to the service-specific access control information, the RRC layer of the UE performs access control for various service access requests according to the service-specific access control information. I do. That is, the NAS converts the mobile station originating service and the mobile station terminating service in the access service type value sent to the RRC layer to the mobile station originating access type (ie, specific mobile station originating service) and service based on the service. Subdivide into the type of mobile incoming call based (ie specific mobile incoming service).

  Specifically, if the UE's RRC layer uses traditional (non-service based) access control information to perform access control, the UE ignores the service based subdivision and Mobile origination type and mobile termination type are included and are provided by NAS using conventional mobile origination control information to perform access control for all mobile origination access types provided by NAS. Conventional mobile station incoming control information is used to perform access control for all mobile terminal incoming access types. When the UE's RRC layer uses service-specific access control information to perform access control, the UE's RRC layer can directly access the service to perform access control for all access types provided by the NAS. Based access control information.

  In a second synchronization method presented in an embodiment of the present invention, when the RRC layer of the UE receives a system broadcast message sent by the network and obtains service-specific access control information from the system broadcast message, The RRC layer sends an instruction to start access control based on the service to the NAS of the UE. After receiving the instruction to initiate service-based access control, the UE's NAS adds the access service type value to the UE's RRC layer access request. The access service type value includes a type of mobile originating access based on the service or a type of mobile terminating access based on the service. The RRC layer of the UE performs access control for various service access requests according to service-specific access control information. The RRC layer of the UE receives the system broadcast message sent by the network, does not obtain service specific access control information from the system broadcast message, and uses the service specific access control information for the UE to perform access control If so, the RRC layer of the UE sends an instruction to stop access control based on the service to the NAS of the UE. After receiving an instruction to stop service-based access control, the NAS of the UE adds the access type value to the access request without adding any further access service type values for the RRC layer of the UE to the access request. To do. The UE stops using service-specific access control information, but at the same time resumes using conventional access control information.

  Specifically, when the RRC layer of the UE receives a system broadcast message that transmits service-specific access control information, the RRC layer of the UE sends an instruction to start access control based on the service to the NAS. Thereafter, with the access service type value to be sent by the NAS to the RRC layer, the mobile originating service and / or the mobile terminating service is the mobile based outbound type based on the service based mobile originating access type and / or service. Further subdivided into types. The RRC layer performs access control for the access type provided by the NAS using access control information based on the service. When the RRC layer of the UE receives a system broadcast message that does not transmit service-specific access control information, and the RRC layer uses the service-specific access control information to perform access control, the RRC layer An instruction to stop the access control is sent to the NAS. Thereafter, with the access service type value to be sent by the NAS to the RRC layer, the mobile originating service and / or the mobile terminating service are no longer mobile based based on the type and / or service based mobile originating access. Not broken down into incoming access types. The RRC layer performs access control for the access type provided by the NAS using conventional (non-service based) access control information.

  The two synchronization methods described above may be combined with the access control presented in other embodiments as detailed below by way of example.

  In the first example, the RRC layer of the UE receives the system broadcast message, obtains conventional access control information from the system broadcast message, and stops the access control for a specific service. Notify NAS. After receiving a notification to stop access control for a particular service, the NAS of the UE sends an access request carrying the access service type. Here, the access service type may include a mobile station originating service or a mobile station terminating service. After receiving the access request, the RRC layer of the UE performs access control for the service corresponding to the access service type according to the conventional access control information.

  In the second embodiment, the RRC layer of the UE receives the system broadcast message and obtains conventional access control information from the system broadcast message. The NAS of the UE sends an access request that carries the access service type. After receiving the access request, the RRC layer of the UE classifies the access service type in the access request as a mobile station originating service and / or a mobile station terminating service, and classifies the access service type according to the conventional access control information. Access control is performed for services corresponding to. The access service type in the access request includes mobile station originated video service, mobile station originated voice service, mobile station originated data service, mobile station originated SMS service, mobile station originated multimedia service, mobile station originated VoIP service or other mobile Mobile incoming service, mobile incoming video service, mobile incoming voice service, mobile incoming data service, mobile incoming SMS service, mobile incoming multimedia service, mobile incoming VoIP service or other mobile incoming services Can be included.

  In the above embodiment, the RRC layer of the UE that performs access control for a specific service corresponding to the access service type according to the service-specific access control information, the RRC layer performs access service type according to the service-specific access control information. This is a process for making a decision regarding access to a specific service corresponding to. If it is determined that a particular service is accessible, the RRC layer sends a connection setup request message carrying a setup cause value. This setup cause value is determined by the RRC layer of the UE according to the mapping relationship between the access service type and the setup cause value and according to the access service type in the access request.

  Embodiments of the present invention determine a setup cause value according to a mapping relationship obtained through a mapping scheme and an access service type in an access request by a UE RRC layer, and a method of mapping an access service type to a setup cause value Provides a method, which resolves the problem of inconsistencies between setup cause values and access service type values in the prior art when the access service type values exceed a limited number of extended setup cause values .

  In the method for mapping an access service type value to a setup cause value according to an embodiment of the present invention, the access service type value includes an emergency service, a high priority access service, a mobile terminal connection service (mt-Access), a mobile Mobile phone signal transmission service (mo-Signaling), Mobile phone call data service (mo-Data) service, Mobile phone call video service (mt-Video), Mobile phone call voice service (mt-Voice), Other mobile phone calls Service (mt-other service), mobile station originated video service (mo-Video), mobile station originated voice service (mo-vVoice), other mobile station originated services (mo-other service), mobile station originated IP multimedia Asabu system signal transmission service (mo-IMSsignaling), mobile originated real-time service (mo-realtime service (e.g., a game)) and there is a SMS.

  In this embodiment, the setup cause values include an emergency service, a high priority access service, an mt-Access service, a mo-Signaling service, a mo-Voice service, a mo-Video service, and a mo-other service.

  Thus, the mapping relationship between the setup cause value and the access service type value in this embodiment may be as follows: the setup cause value corresponds to an access service type value of the same name, and the access service type value If the name is not the same as the name of the setup cause value, the access service type value is mapped according to the mobile originating type or the mobile terminating type, i.e. all mobile originating access service type values are Corresponding to one, all mobile incoming access service type values correspond to another value between the setup cause values.

  For example, the mapping relationship between the setup cause value and the access service type value may be as follows. The setup cause value corresponds to an access service type value of the same name, and if the name of the access service type value is not the same as the name of the setup cause value, the mobile incoming access service type is the mobile incoming setup cause value (mt Corresponding to (Access), the mobile station transmission access service type corresponds to a mobile station transmission setup cause value (mo-other service). FIG. 5 is an instance of a mapping relationship between a setup cause value and an access service type value according to an embodiment of the present invention. In practice, there may be multiple different service types such as VoIP service and multimedia service, and the mapping relationship may be set according to the mapping scheme presented in this embodiment.

  In this embodiment, the mapping relationship between the access service type value and the setup cause value may be stored in the UE. After the RRC layer of the UE has made a decision regarding access control for the access service type value provided by the NAS, for the allowed access type, the UE is transmitted in the RRC setup request message according to the stored mapping relationship. An RRC setup request message is sent by mapping the access service type value to the setup cause value. For example, if the UE determines that the emergency call service is accessible, the sent RRC setup request message carries the emergency call setup cause value. If the UE determines that the mo-IMS signaling service is accessible, the sent RRC setup request message carries setup cause values for other mobile originating services.

  This embodiment solves the problem that the number of RRC setup cause values is limited and the RRC setup cause values cannot match the access service type value. Furthermore, the method presented in this embodiment is applicable in other scenarios. In particular, the mapping method is applicable to more scenarios and is not limited to being combined with the access control method presented in the embodiment of the present invention.

  Those skilled in the art will appreciate that all or part of the steps in the methods described in any of the preceding embodiments may be performed by a program that indicates the associated hardware. The program may be stored in a computer readable storage medium. When the program runs, at least the following steps are performed.

  The access control method includes determining whether the UE needs to perform access control for a particular service and sending a system broadcast message to the UE, where the system broadcast message indicates that the UE has a specific service. Service-specific access control information is transmitted when access control needs to be performed for a system broadcast message or conventional access control when the UE does not need to perform access control for a particular service Transmit information.

  The access control method includes a step of receiving a system broadcast message for transmitting service-specific access control information by the UE and a step of performing access control for a specific service according to the service-specific access control information.
