BEST MODE FOR CARRYING OUT THE INVENTION The inventive concept of the present invention is: The base station counts the occupancy of air interface resources in real time or periodically. When the user equipment (UE) initiates a service request, the base station determines whether to allow access to the service initiated by the UE according to the occupancy condition of the air interface resource. Specifically, the base station pre-stores an air interface parameter, where the air interface parameter is used to indicate the subscription information of the air interface resource on the base station, and the base station determines, as the base station, whether to allow access to the service initiated by the UE, according to one of The carrier and the access network sign differently, and the content of the air interface parameters saved by the base station is also different. The signing method is one of the following three methods: In the first mode, one or more operators on the base station respectively subscribe to rent fixed-size air interface resources, that is, one or more operators have their own dedicated air interface resources, and do not provide sharing. For the air interface resource, the air interface parameters on the base station include: the air interface resource size information subscribed by the operator sharing the base station, that is, the dedicated air interface resource of one or more operators. Manner 2: One or more operators on the base station respectively subscribe to lease fixed-size air interface resources, and use part of the air interface resources as shared air interface resources, allowing other operators to lease the shared air interface resources, that is, one or more The air interface resources contracted by the operators include dedicated air interface resources and shared air interface resources; the shared air interface resources in all air interface resources together form a shared air interface resource pool; when some operators are not excluded, some operators provide The air interface resources are shared, while the other operators do not provide the shared air interface resources. For the subscription mode 2, the air interface parameters on the base station include any of the following groups of parameters:

• Exclusively sharing or sharing the air interface resource size information signed by the operator of the base station and the shared air interface resource size information available to other operators in the air interface resources contracted by the operator;

• Exclusively sharing or sharing the air interface resource size information signed by the operator of the base station and the dedicated air interface resource size information for the dedicated air interface resources subscribed by each operator; * Exclusively sharing or sharing the shared air interface resource size information shared by other operators in the air interface resources signed by the operator of the base station and the dedicated air interface resource size information for exclusive use;

* Exclusively sharing or sharing the air interface resource size information signed by the operator of the base station, the shared air interface resource size information available to other operators in the air interface resources contracted by the operator, and a dedicated air interface for exclusive use by itself Resource size information. In the third mode, the base station reserves a part of the air interface resource as the shared air interface resource, that is, the shared air interface resource pool, and one or more operators on the base station respectively sign the air interface resources except the shared air interface resources as their respective dedicated air interfaces. Resources. For the subscription mode 3, the air interface parameters on the base station include: air interface resource size information subscribed by the operator of the base station or shared, and shared air interface resource size information reserved by the base station.

The base station calculates the occupancy of the air interface resource in real time or periodically as another reference condition for determining whether to allow access to the service initiated by the UE. Specifically, the base station performs real-time or periodic statistics on the air interface resources occupied by the one or more operators according to the ongoing service of the operator sharing or sharing the base station. The base station limits the air interface resources of the operator who exclusively or shares the base station according to the results of the real-time or periodic statistics and the pre-saved air interface parameters, so as to prevent an operator from occupying too many air interface resources and causing other operators to The quality of the user's business is damaged. The step of determining, by the base station, whether to allow access to the service initiated by the UE according to the occupation of the air interface resource includes: the remaining air interface resource of the operator to which the UE belongs and the air interface resource that is expected to be required for the service to be accessed For comparison, if the carrier's remaining air interface resources can satisfy the service access, the service initiated by the UE is allowed to be accessed. If the remaining air interface resources of the operator cannot satisfy the service access, the service establishment fails.

When the UE initiates the service, the base station obtains the latest remaining air interface resources of the operator by querying; 3) when the UE initiates the service, the base station calculates the operation in real time. The remaining air interface resources of the quotient. The operator to which the UE belongs is obtained by the base station from the core network side or from the UE side when the UE establishes a connection with the core network. Further, the base station learns the cell to which the UE belongs by using the cell that represents the operator information of the UE that is carried in the initial context setup request sent by the core network, or the base station is in the radio resource control by the UE (Radio) Resource Control, RRC) Establishes a cell that carries the operator information of the UE that is carried in the request message, and learns the operator to which the UE belongs.

The invention will be further described below in conjunction with the drawings and specific embodiments. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other. As shown in Figure 2, Carrier A and Carrier B share the access network. Currently, Carrier A has three users: UEa, UEb, and UEc. Currently, Carrier B also has three users: UE1, UE2, and UE3. Embodiment 1 is an example of resource admission control when an operator and a base station subscribe to the first subscription mode; Embodiment 2 is an example of resource admission control when an operator and a base station sign a contract with the second subscription mode; 3 is an example of resource admission control when the operator and the base station sign a contract with the third subscription method. Embodiment 1 Operator A and Carrier B respectively subscribe to a fixed-size air interface resource with the access network, that is, use the foregoing contract mode one. The eNodeB configures air interface parameters according to the subscription content, and the air interface parameters include air interface resource size information subscribed by the operator sharing or sharing the eNodeB. After the contracted air interface resource takes effect, the eNodeB starts the real-time or periodic statistics of the air interface resource, and performs statistics on the air interface resource occupancy of the operator A and the operator B respectively. The eNodeB can periodically calculate the available air interface resources of each operator according to the air interface parameters and the air interface resource occupancy, that is, the remaining air interface resources. As shown in FIG. 4, the resource admission control method in this embodiment includes the following steps: Step 401: The UE3 establishes a connection with the core network, and the eNodeB detects the carrier to which the UE3 belongs. It is the operator B; the eNodeB can obtain the operator information of the UE from the core network side or the UE side itself, for example, the cell that represents the operator information of the UE that is carried in the initialization context establishment request sent by the core network, and learns that the UE belongs to Or, in the process of establishing an RRC connection with the eNodeB, the UE notifies the eNodeB of the operator information to which the UE belongs by using the cell that carries the operator information of the UE that is carried in the RRC setup request message. Step 402: The UE3 initiates a service, and the eNodeB queries the remaining air interface resources of the operator B.

In this embodiment, the eNodeB periodically calculates the remaining air interface resources of each operator, and queries when the user equipment initiates the service. In other embodiments, the eNodeB can also perform calculations in real time. Step 403: The eNodeB compares the remaining air interface resources of the operator B with the air interface resources that are required by the UE3 to be accessed. If the remaining air interface resources of the operator B meet the requirements of the service to be accessed, the eNodeB accepts The service is also scheduled and allocated; if the remaining air interface resources of the operator B do not meet the requirements of the service to be accessed, no scheduling is performed.

Embodiment 2 Operator A and Carrier B respectively subscribe to a fixed-size air interface resource with the access network, and use a part of the air interface resource as a shared air interface resource, and allow the other party to borrow, that is, use the foregoing contract mode 2. The operator decides on its own whether to provide shared air interface resources and how much shared air interface resources are provided. The eNodeB configures an air interface parameter according to the content of the subscription, where the air interface parameter includes: an air interface resource size information signed by an operator sharing or sharing the eNodeB, and an air interface resource signed by the operator is available for sharing by other operators. The shared air interface resource size information; or includes: air interface resource size information signed by an operator sharing or sharing the eNodeB; and dedicated air interface resource size information for the dedicated air interface resource subscribed by the operator; Or including: sharing or sharing the shared air interface resource size information shared by other operators in the air interface resources subscribed by the operator of the eNodeB, and the dedicated air interface resource size information for private use; or including: exclusive Or the air interface resource size information signed by the operator sharing the eNodeB, and the air interface resource signed by the operator. Shared air interface resource size information shared by other operators and dedicated air interface resource size information for its own use. The eNodeB starts the real-time or periodic statistics of the air interface resources after the contracted air interface resources take effect, and separately calculates the air interface resource occupancy of the operator A and the operator B, including the occupation of the dedicated air interface resources and the shared air interface resources. Occupation situation. The eNodeB can periodically calculate the remaining air interface resources of each operator on it, including the remaining shared air interface resources and the remaining dedicated air interface resources. As shown in FIG. 5, the resource admission control method in this embodiment includes the following steps: Step 501: The UE3 establishes a connection with the core network, and the eNodeB detects that the operator to which the UE3 belongs is the operator B. In step 502, the UE3 initiates a service, and the eNodeB queries. The remaining air interface resources of the operator B, including the remaining shared air interface resources and the remaining dedicated air interface resources; Step 503, the eNodeB performs the remaining air interface resources of the operator B and the air interface resources that are required by the UE3 to be accessed. If the remaining air interface resources of the carrier meet the requirements of the service to be accessed, step 505 is performed; if the remaining air interface resources of the carrier do not meet the requirements of the service to be accessed, step 504 is performed; Step 504, eNodeB query In the present embodiment, the eNodeB queries the remaining shared air interface resources provided by the operator A to determine whether the remaining shared air interface resources meet the requirements of the to-be-accessed service. If yes, go to step 505; if not, then not Preferably, in this step, the base station can comprehensively consider the remaining air interface resources of the operator B and the remaining shared air interface resources in the shared air interface resource pool provided by other operators, that is, determine the remaining air interface resources of the operator B. Whether the sum of the remaining shared air interface resources meets the requirements of the service to be accessed, if yes, step 505 is performed, and if not, no scheduling is performed. For example, operator A signs 20M air interface resources, 5M of which acts as a shared air interface resource and 15M as a dedicated air interface resource. Operator B signs 15M air interface resources, of which 5M is the shared air interface resource and 10M is the dedicated air interface resource. When the air interface resource of the operator B is only 1 M, the service initiated by the UE1 under the operator B is required to apply for the 2M air interface resource. The base station judges that the air interface resource of the operator B is occupied by 19M, and the remaining air interface The resource is only 1M, and the air interface resource of the operator A occupies 18M, and the remaining shared air interface resource is 2M. At this time, the base station can allocate the 1M remaining air interface resource of the operator B and the 1M remaining shared air interface of the operator A. The resource is allocated to UE1, and the 2M remaining shared air interface resources of operator A may also be allocated to UE1. Step 505, accepting the service and giving resource scheduling and allocation.

Embodiment 3 In this embodiment, the eNodeB reserves a part of the air interface resource as the shared air interface resource, and the operator A and the operator B respectively subscribe to the air interface resource of the access network except the shared air interface resource, that is, the foregoing Signing method three. The eNodeB configures the air interface parameters according to the subscription content, where the air interface parameters include: air interface resource size information subscribed by the operator that shares or shares the eNodeB, and reserved shared air interface resource size information. The eNodeB starts the real-time or periodic statistics of the air interface resources after the contracted air interface resources take effect, and is used to collect the following information: the air interface resource occupancy of each operator and the occupation of the shared air interface resources. The eNodeB can periodically calculate the remaining air interface resources, including the remaining air interface resources of each operator and the remaining shared air interface resources. As shown in FIG. 6, the resource admission control method in this embodiment includes the following steps: Step 601: The UE3 establishes a connection with the core network, and the eNodeB detects that the operator to which the UE3 belongs is the operator B. In step 602, the UE3 initiates a service, and the eNodeB queries. The remaining air interface resources of operator B, and the remaining shared air interface resources; the step of querying the remaining shared air interface resources may also be performed in step 604. Step 603: The eNodeB compares the remaining air interface resources of the operator B with the air interface resources that are required by the UE3 to be accessed. If the remaining air interface resources of the carrier meet the requirements of the service to be accessed, step 605 is performed. If the remaining air interface resources of the carrier do not meet the requirements of the service to be accessed, step 604 is performed; Step 604, the eNodeB determines whether the remaining shared air interface resources meet the requirements of the service to be accessed. If yes, perform step 605; if not, do not schedule; preferably, the eNodeB can comprehensively consider the remaining dedicated air interface resources of the operator B and the remaining shared air interface resources provided by the eNodeB, and determine the remaining dedicated air interface. Whether the sum of the resource and the remaining shared air interface resources satisfies the resource requirements of the service to be accessed, and if so, allocates resources to the UE3 from the remaining shared air interface resources, or from the remaining dedicated air interface resources and the remaining shared air interface resources. Step 605: Accept the service and give resource scheduling and allocation.

The above embodiment is described by taking the two operators' shared access network as an example. When multiple operators share the access network, the resource admission control method is the same. The above resource admission method can also be used when only one operator has exclusive access to the network.
