Description

The present invention relates to the field of communications, and in particular to a method and system for controlling access to a home base station. BACKGROUND OF THE INVENTION The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3GPP) is evolved by the Evolved Universal Terrestrial Radio Access Network (referred to as Evolved Universal Terrestrial Radio Access Network). E-UTRAN), Mobility Management Entity (MME), Serving Gateway (S-GW), Packet Data Network Gateway (P-GW) The Home Subscriber Server (HSS) is composed of a Home Subscriber Server (HSS). FIG. 1 is a schematic structural diagram of a HeNB accessing an EPS in a non-roaming scenario according to the related art. The architecture of the EPS will be described below with reference to FIG.

The MME is connected to the EUTRAN, the S-GW, and the Home evolved NodeB (HeNB) gateway (HeNB GW), and is responsible for control planes such as mobility management, non-access stratum signaling processing, and user mobility management context management. Related work; S-GW is an access gateway device connected to E-UTRAN, which forwards data between E-UTRAN and P-GW, and is responsible for buffering paging waiting data; P-GW is EPS and packet Data Network (referred to as PDN) The border gateway of the network, responsible for PDN access and forwarding data between EPS and PDN. If the EPS system supports the Policy and Charging Control (PCC), the Policy and Charging Rules Function (PCRF) performs the policy and charging rules. The Rx is connected to an application function (Application Function, abbreviated as AF) in the service network protocol of the Internet Protocol (IP), and obtains service information, which is used to generate service information of the PCC policy. When the S5 interface between the S-GW and the P-GW uses the GTP protocol, the P-GW resides in the Policy and Charging Enforcement Function (PCEF), between the PCRF and the P-GW. The Gx interface exchanges information, and is responsible for initiating the establishment, modification, and release of the bearer, ensuring the quality of service (Quality of Service, QoS for short), and performing charging control. When the S5 interface of the S-GW and the P-GW uses Proxy Mobile IP (PMIP), the S-GW hosts the Bearer Binding and Event Report Function (Bearer Binding and Event Report Function, It is abbreviated as BBERF), and the S-GW and the PCRF exchange information through the Gxc interface. The BBERF is responsible for initiating the establishment, modification and release of the bearer to ensure the service quality of the service data, and the PCEF performs the charging control.

The EPS supports the access of the HeNB, which is a small, low-power base station deployed in indoor places such as homes and offices. Closed Subscriber Group (CSG) is a new concept introduced after the introduction of home base stations. Usually a family or an internal user of a company forms a closed user group, which is identified by a CSG ID. The home base station for the user's monthly service in this closed subscriber group has the same CSG ID. When a closed subscriber group is served by only one home base station, the closed subscriber group can also directly identify the home base station identity (e.g., BS ID). At the will of the home base station manager, CSG users and/or non-CSG users can distinguish between different levels, and the priority of the service that they enjoy is different, and the quality of the service and the type of service can be different. By signing with the operator, the user can access the home base station corresponding to multiple closed user groups, for example, the user's office, home, and the like. Therefore, the concept of allowing a closed user group list to be introduced is introduced. This list is stored in the user's terminal and the user data server on the network side. There are three usage modes for home base stations: closed mode, mixed mode, and open mode. When the home base station is in the closed mode, only the CSG subscription user to which the home base station belongs can access the base station and enjoy the services provided by the base station. When the home base station is in the open mode, any operator subscription subscriber can access the base station, and the home base station at this time is equivalent to the macro base station. When the home base station is in the hybrid mode, any operator subscription or roaming user is also allowed to access, but different levels are classified according to whether the user subscribes to the CSG, that is, the user who signs the CSG is using the hybrid home. Base stations have higher service priorities and enjoy better quality of service and service categories. When the user initiates the access, the user data server on the network side sends the closed subscriber group that the user subscribes to and allows access to the mobility management entity of the core network. The core network mobility management entity will use this information to perform access control on the UE. If the UE accesses the core network from an unlicensed closed mode home base station, the core network will deny access to such users.

The HeNB usually accesses the core network of the EPS through a leased fixed line. To ensure the security of the access, a security gateway (SeGW) is shielded in the core network. The data between the HeNB and the SeGW will be encapsulated with IPSec. The HeNB can directly connect to the MME and the S-GW of the core network through the IPSec tunnel established by the HeNB and the SeGW, and can also connect to the MME and the S-GW through the HeNB GW. At the same time, in order to implement management of the HeNB, a Home eNodeB Management System (HeMS) is introduced. „ The QoS of the fixed line that is accessed by the HeNB is usually the owner of the HeNB and the fixed network operator. Therefore, when the 3GPP UE usually accesses the 3GPP core network access service, the required QoS cannot exceed the subscription QoS of the fixed network line that the fixed network operator can provide. Otherwise, the QoS of the UE access service There is no guarantee, especially Guaranteed Bitrate (GBR). Therefore, for 3GPP networks, the total QoS requirement for service access of all UEs accessed through the HeNB must not exceed that of the HeNB. QoS guarantee for fixed line subscription. jt匕, Universal Mobile Telecommunications System (UMTS) also supports access to home base station HNB (Home NodeB). Figure 2 is a non-roaming scenario according to the related art. Schematic diagram of the architecture of the HNB accessing UMTS. Figure 2 is similar to the architecture of Figure 1, except that the service general packet radio service is used. The Serving General Packet Radio Service Support Node (SGSN) replaces the S-GW and replaces the P-GW with a Gateway General Packet Radio Service Support Node (GGSN). In the case where the base station is connected through the contracted fixed line, it is necessary to consider the scenario in which multiple home base stations (for example, HeNB, HNB) access the 3GPP core network through a contracted fixed line. In this case, for the 3GPP network, it must be controlled. All user equipment accessed through the multiple home base stations

The total QoS requirement for service access (User Equipment, UE for short) does not exceed the subscription QoS guarantee of the same fixed line that the multiple home base stations access. In the related art, when different user equipments sharing the same fixed-line network line are accessed by one or more home base stations, the total bandwidth of the user equipment sharing the same fixed-line line cannot be controlled so as not to exceed the Signed QoS guarantee for signing fixed line.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. In the following embodiments, the MME or the home base station gateway (HeNB GW or HNB GW) obtains the subscription bandwidth of the subscription fixed network line for the home base station access, and the parameter indicates that the home base station owner and the fixed network operator have signed the lease. The fixed network line transmits the total bandwidth that can be guaranteed by the service access accessed by the home base station. FIG. 3 is a flowchart of a method for controlling home base station access according to an embodiment of the present invention. As shown in FIG. 3, the process includes the following steps: Step S302: The MME or the home base station gateway obtains the subscription fixed network line for home use. The subscription bandwidth of the base station access, wherein the home base station using the contracted fixed network line is registered in the MME or the home base station gateway; Step S304, the MME or the home base station gateway accesses all users accessing the home base station according to the subscription bandwidth. The service access of the device performs QoS control. Through the foregoing steps S302 to S304, the MME or the home base station gateway performs QoS control on the service access of all the user equipments that are accessed, and solves the problem that the total bandwidth of the user equipments sharing the same contracted fixed network line cannot be controlled in the related art. problem.

The MME or the home base station gateway can obtain the subscription bandwidth for the home base station access of the subscription fixed network line by using at least one of the following manners: Method 1: directly configuring the subscription fixed network line corresponding to the home in the MME or the home base station gateway The subscription bandwidth of the base station access; the second mode, the subscription bandwidth of the fixed base network line used by the home base station to the MME or the home base station gateway for the home base station access. It should be noted that, in the scenario that multiple home base stations (HNBs, HNBs) access the 3GPP core network through a contracted fixed network line, the multiple home base stations will register with the same MME, HeNB GW or HNB GW, and register. The contracted fixed-line line for the home base station access is the same (the broadband connection information can also be reported at the same time), that is, the home base station registers with the MME or the home base station to the MME or the home base station. The gateway sends a message, where the message carries the subscription bandwidth. Therefore, the MME, the HeNB GW, or the HNB GW can determine that the signed subscription bandwidth of the reported fixed-line fixed-line for home base station access is applied to the service access QoS control of all user equipments accessed through the home base stations. The acquisition of the subscription bandwidth by the home base station through the home base station management system will be described below with reference to FIG. 4 is a flowchart of a home base station acquiring a subscription bandwidth of a subscription fixed network line for home base station access according to an embodiment of the present invention, where the home base station HeNB/HNB is managed to a home base station. In the process of registering the HeMS/HMS system, the contracted fixed network line is used for the subscription bandwidth of the home base station access, and the process includes the following steps: Step S401: After the home base station is powered on, establish a secure connection with the home base station management system by using the fixed line and the home base station. IP connection; Step S402, the home base station sends a message to the home base station management system, where the message carries the device identifier of the home base station and current location information (ie, broadband connection information), where the location information includes a home gateway accessed by the home base station The public IP address of the Residential Gate Way (referred to as RGW) may also be the line identifier of the RGW, or may be the username of the home base station owner and the fixed network operator; Step S403, after the home base station management system saves the information, Returning the response message; Step S404, the home base station management system sends a message to the home base station to set the parameter value, including: the S1 interface IP address of the home base station accessing the core network, the cell identity of the home base station, and the contracted fixed network line for the home The subscription bandwidth of the base station access; step 4 gathers S405, the home base station saves After the message, it returns an acknowledgment message. Preferably, the home base station can also obtain the subscription bandwidth through the home subscriber server. For example, when the H(e)NB establishes a secure IP connection with the SeGW, the SeGW interacts with the HSS, and the HSS uses the contracted fixed network line for the home base station. The incoming subscription bandwidth is sent to the H(e)NB. 5 is a flowchart of reporting, by a HeNB, a subscription bandwidth for a home base station access to a MME by a HeNB, according to an embodiment of the present invention, where the HeNB reports the subscription to the MME when registering with the MME. The network line is used for the process of the subscription bandwidth of the home base station access. The flowchart includes the following steps: Step S501: After the HeNB is powered on, establish a secure IP connection with the MME through the fixed network line; Step S502, the HeNB sends a message to the MME. Carrying the HeNB identifier, and the broadband connection information, and signing the fixed network line for the subscription bandwidth of the home base station access. The broadband connection information may be a public IP address of the RGW to which the HeNB is connected, or may be a line identifier of the RGW, or may be a username that the HeNB owner subscribes to the fixed network operator. Step S503: After the MME saves the information, the MME returns Reply message. After the HeNB accesses the core network architecture through the HeNB GW, after the HeNB is powered on, the HeNB uses a similar procedure to notify the HeNB GW of the broadband connection information accessed by the HeNB and the subscription bandwidth used by the subscription fixed network line for the home base station access. FIG. 6 is a flowchart of reporting, by the HNB, the subscription bandwidth for the home base station access of the subscribed fixed network line that the HNB accesses to the HNB GW according to an embodiment of the present invention, where the HNB is registered with the HNB GW. 4) The process of signing a fixed-line line for the subscription bandwidth of the home base station access, the process includes the following steps: Step S601: After the HNB is powered on, establish a secure IP connection with the HNB GW through the fixed line; Step S602, HNB The HNB GW sends a message, where the message carries the HNB identifier, the broadband connection information, and the subscription bandwidth of the subscription fixed line for the home base station access. The broadband connection information may be a public IP address of the RGW to which the HeNB is connected, or may be a line identifier of the RGW, or may be a user name signed by the HNB owner and the fixed network operator; Step S603, after the HNB GW saves the information, return Reply message. Through the flow of FIG. 4, FIG. 5, and FIG. 6, the MME, the HeNB GW, or the HNB GW acquires the broadband connection information of the access of the HeNB/HNB and the subscription bandwidth of the corresponding subscription fixed line for the home base station access. Therefore, the MME, HeNB GW or HNB GW applies the subscription bandwidth of the upper fixed-line subscription fixed line for home base station access to the service access QoS control of all users accessed through the home base station. Preferably, the subscription bandwidth for the home base station access corresponding to the subscription fixed network line can also be configured directly at the MME or the home base station gateway. When the PDN connection established by the UE accessed by the home base station performs the procedure for establishing or modifying the bearer, the MME, the HeNB GW or the HNB GW performs QoS authorization according to the currently available fixed network bandwidth, CSG information, user priority, and the like. The process includes the following steps: Step S1: After the user equipment establishes a PDN connection through the home base station gateway, the MME or the home base station gateway receives a request message for creating or modifying a bearer, where the QoS parameter in the request message includes protection Bandwidth GBR ( Guaranteed Bitrate); Step S2, the MME or the home base station gateway determines whether to accept the creation or modification of the bearer request according to the GBR increment and the remaining available bandwidth of the contracted fixed line. The increment of GBR here can be expressed Two meanings, (1) If the message is a bearer request message, the GBR carried in the message is the GBR increment in the step; (2) if the message is a modify bearer request message, the GBR increment is The difference between the GBR carried in the message and the assigned GBR. That is, for creating a bearer request message, the GBR increment value is the GBR in S1; for the modify bearer request message, the GBR increment value is the difference between the GBR in S1 and the 7-assigned GBR. Preferably, in step S2, if the GBR increment is less than or equal to the remaining available bandwidth, the MME or the home base station gateway accepts to create or modify the bearer request. Preferably, in step S2, if the GBR increment is greater than the remaining available bandwidth, the MME or the home base station gateway determines whether to initiate release of other bearer resources; if the MME or the home base station determines to initiate release of other bearer resources, then release After the resource, accept the create or modify the bearer request, otherwise, refuse to create or tamper with the load request. The MME or the home base station gateway determines whether to initiate the release of other bearer resources according to at least one of the following: a priority ARP of the bearer, and user CSG information. Based on the prior art, after the UE attaches and establishes a PDN connection through the home base station, the MME, the HeNB GW, or the HNB GW can acquire the user CSG information. The user CSG information includes an access mode in which the user equipment accesses the home base station, and includes: a closed mode, a mixed mode, and an open mode. If the home base station is in the hybrid mode, there is also a membership indication in the user CSG information, and the indication is divided into a CSG user and a non-CSG user. The establishment and the 4 tampering will be described below with reference to FIG. 7 and FIG. 8 respectively. FIG. 7 is a flowchart of policy control performed by a MME in a bearer process for establishing a bearer bandwidth for a home base station access according to a contracted fixed network line according to an embodiment of the present invention, where the UE describes that a PDN connection is established by accessing an EPS by a HeNB, and the UE The network needs to request a new QoS resource for accessing the service, and the network decides to initiate the process of establishing a dedicated bearer. In this flow, the HeNB is directly connected to the MME. The process includes the following steps: Step S701: The P-GW sends a create bearer request message to the S-GW, where the message carries the QoS parameters of the bearer, including QCI, ARP, GBR, and MBR. The P-GW triggers the PCC rule provisioning from the PCRF, the local configuration of the P-GW, or the QoS request of the UE. Step S702: The S-GW sends a create bearer request message to the MME, where the message carries the QoS parameters of the bearer, including the QCI. ARP, GBR and MBR; Step S703, the MME will make the following policy decision:

(a) If the requested GBR is less than or equal to the remaining available bandwidth of the currently contracted fixed line (the MME obtains the remaining available bandwidth according to the obtained contracted fixed line for the home base station access and the allocated bandwidth), then the steps are performed. S707;

(b) If the requested GBR is greater than the remaining available bandwidth of the currently contracted fixed line, the MME further performs the following logical judgment:

( bl ) If the HeNB access mode is in the open mode, the MME compares the bearer with other GBR bearers established by the user and other GBR bearers established by other users connected by the same contracted fixed line according to the ARP. If the bearer cannot preempt other bearer resources, step 4 is performed to gather S704. If the load can preempt other resources, step 4 is performed S706;

(b2) If the mode accessed by the HeNB is a hybrid mode, and the member relationship of the UE corresponding to the bearer is a non-CSG user:

(b21) If there are other GBR bearers established by the user or other bearers established by other non-CSG users accessed by the same contracted fixed line, then the MME compares the bearers with other bearers according to ARP, if If the bearer cannot preempt the resources of other bearers, step S704 is performed. If the bearer can preempt the resources of other bearers, step S706 is performed;

(b22) If there are no other GBR bearers established by the user or other GBR bearers established by other non-CSG users accessing the same fixed line, then step S704 is performed.

(b3) If the access mode of the HeNB is a hybrid mode, and the member relationship of the UE corresponding to the bearer is a CSG user:

(b31) If there are other GBR bearers established by other non-CSG users accessing through the same contracted fixed line, step S706 is performed;

(b32) If there is no other GBR bearer established by the non-CSG user accessing through the same contracted fixed line, the MME will bear the other GBR carried by the user according to the ARP or connect through the same contracted fixed line. If other bearers of the other CSG users are compared, if the bearer cannot preempt the resources of other bearers, step S704 is performed. If the bearer can preempt other bearer resources, step S706 is performed; (b4) If the access mode of the HeNB is in the closed mode, the MME compares the bearer with other GBRs established by the user or the GBR bearers established by other users connected by the same contracted fixed line according to the ARP, If the bearer cannot preempt other bearer resources, step 4 is performed to gather S704. If the load can preempt other resources, step 4 is performed S706; Step S704, the MME returns a create response to the S-GW to reject the load establishment; Step S705, the S-GW returns a create bearer response to the P-GW, rejecting The bearer is set up, and the process ends. Step S706: Perform a dedicated bearer deactivation process initiated by the MME, and release the resources of the other bearers that are preempted. This step can be implemented by using the existing technology, and is not described here again. Step 4: S707, the wireless 7 is set up; Step S708, the MME returns a Create Bearer Reply message to the S-GW to accept the bearer establishment; Step S709, S-GW The bearer reply message is returned to the P-GW to accept the bearer establishment. For the scenario in which the HeNB is connected to the MME through the HeNB GW, the HeNB GW performs the resuming judgment of the MME in the above process, and in step S706, the HeNB GW sends a message to notify the MME to initiate the deactivation process of the dedicated bearer. FIG. 8 is a flowchart of policy control performed by an MME in a modified bearer procedure based on a subscription bandwidth for a home base station access by a contracted fixed network line, where the figure describes that a PDN connection is established by accessing an EPS by a HeNB, and the UE Due to the need to access the service, the network needs to tamper with the allocated QoS resources, and the network decides to initiate the process of modifying the proprietary bearer. The process includes the following steps: Step S801: The P-GW sends an update bearer request message to the S-GW, where the message carries the updated QoS parameters, including QCI, ARP, GBR, and MBR. The P-GW triggers the PCC rule provisioning from the PCRF, the local configuration of the P-GW, or the QoS request of the UE. In step S802, the S-GW sends an update bearer request message to the MME, and carries the QoS parameters of the bearer update, including QCI and ARP. GBR and MBR; Step S803, the MME will make the following policy decisions:

(a) If the requested GBR increment (ie, the difference between the updated GBR and the pre-updated GBR) is less than or equal to the remaining available bandwidth of the currently contracted fixed line (the MME is based on the obtained contracted fixed line) For the home base station access subscription bandwidth and the allocated bandwidth calculation to obtain the remaining available bandwidth), step S807 is performed;

(b) If the requested GBR increment is greater than the remaining available bandwidth of the currently contracted fixed line, the MME further performs the following logical judgment:

( bl ) If the HeNB access mode is in the open mode, the MME compares the bearer with other GBR bearers established by the user and other GBR bearers established by other users connected by the same contracted fixed line according to the ARP. If the bearer cannot preempt other bearer resources, perform step 4 S804. If the ^ load can preempt other resources, perform step 4 S806;

(b21) If there are other GBR bearers established by the user or other bearers established by other non-CSG users accessed by the same contracted fixed line, then the MME compares the bearer with other bearers according to ARP, if If the bearer cannot preempt the resources of other bearers, step S804 is performed. If the bearer can preempt the resources of other bearers, step S806 is performed;

(b22) If there are no other bearers established by the user or other non-CSG users established by the same contracted fixed line, then step S804 is performed.

(b31) If there are other GBR bearers established by other non-CSG users accessing through the same contracted fixed line, step S 806 is performed;

(b32) If there is no other GBR bearer established by other non-CSG users accessing through the same contracted fixed line, the MME carries the bearer and other GBRs established by the user according to the ARP or through the same contracted fixed network. The other bearers established by other CSG users connected to the line are compared. If the bearer cannot preempt the resources of other bearers, step S804 is performed. If the bearer can preempt other bearer resources, step S806 is performed;

(b4) If the access mode of the HeNB is in the closed mode, the MME compares the bearer with the GBR bearer established by the user or other users established by the same contracted fixed line, according to the ARP, if the bearer If the resources of other bearers cannot be preempted, go to step 804. If the bearer can preempt other bearer resources, step S806 is performed; Step S804, the MME returns an update bearer response to the S-GW, and rejects the tampering; in step S805, the S-GW returns an update bearer response to the P-GW, rejects the tampering, and the process ends; step S806, Perform the dedicated bearer deactivation process initiated by ΜΜΕ to release the resources of other bearers that are preempted.
