When the user equipment in the group accesses the wireless network, the home subscriber server provides the group policy control information to which the user equipment belongs to the mobility management network element. The mobility management network element controls the state of the user equipment accessing the wireless network in the group according to the control policy in the group policy control information. Therefore, the state in which the user equipment in the group accesses the wireless network is controlled according to the access requirements of different groups.

The above is the core idea of the present invention. In order to enable a person skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to FIG. 1, a schematic flowchart of a method for controlling a group access wireless network according to an embodiment of the present application is shown. The network architecture of the wireless network of the present application may be various, for example, may be an Evolved Universal Mobile Telecommunication System (UMTS), or an Evolved Universal Mobile Telecommunication System Territorial Radio Access Network (E-UTRAN). UMTS Territorial Radio Access Network (UTRAN), Global System for Mobile Communications (GSM), Enhanced Data Rate for GSM Evolution (EDGE), Wireless GSM EDGE Radio Access Network (GERAN) A wireless network architecture such as the 3rd Generation Partner Project (3GPP) network.

The method is applied to a mobility management network element in a wireless network. The mobility management network element in the present application may be a Mobility Management Entity (MME) in E-UTRAN, and a service general packet in UTRAN/GERAN. General Packet Radio Service (GPRS), Serving GPRS Supporting Node (SGSN). The gateway device may be a Serving Gateway (S-GW), a Packet Data Network Gateway (P-GW), a General Packet Radio Service (GPRS), and a support node (Gateway). GPRS Supporting Node, GGSN) and other network elements.

The method can include the following steps:

101. Receive an access request message sent by a user equipment in the group. The method of this embodiment is applied to a mobile network element.

In the embodiment of the present invention, the user equipment (User Equipment, UE) may be any one of the following, and the UE may be static or mobile. The static UE can be a terminal, a mobile station, a subscriber unit, or a station. The mobile UE can be a cellular Cellular Phone, Personal Digital Assistant (PDA), wireless modem (modem), wireless communication device, hand-held device (handh _e ld), laptop computer (Laptop Computer) cordless phone (Cordless Phone) or Wireless Local Loop (WLL) station, etc. The above UEs may be distributed throughout the wireless network.

When the user equipment in the group accesses the wireless network, an access request message requesting access to the wireless network is first sent to the mobility management network element of the wireless network.

The access request message may be an Attach Request message, a Routing Area Update Request message, a Tracking Area Update Request message, a Service Request message, or an extended service. Request (Request Service) message, Packet Data Network Connectivity Request message, Activate Packet Data Protocol Context Request message, Bearer Resource Modification Request message Or modify the request message such as the Modify Packet Data Protocol Context Request message.

102. Acquire, according to the access request message, group policy control information of the group.

The group policy control information includes, but is not limited to: a preset time range in which the group allows the user equipment to access the wireless network, a preset number range of the user equipment that the group allows to access the wireless network at the same time, and the group permission is The user equipment allocates a preset range of bearer numbers. The preset time range in which the group allows the user equipment to access the wireless network may be set according to the user needs of the group. For example, the user wants the user equipment in the group to access the wireless network from 8:00 am to 9:00 every day. The preset time range in which the group allows the user equipment to access the wireless network in the group policy control information is 8-9 points. The preset number of user devices that the group allows to access the wireless network at the same time or the group allows the user equipment to allocate a preset number of bearers for the bearer, which can be set according to the load condition of the wireless network.

In a possible implementation manner of the present application, the step 102 may be implemented by using the method shown in FIG. 2a: 210, sending a subscription data request message to an HSS (Home subscriber server) according to the access request message; The subscription data request message is used to request the HSS to provide group subscription data of the group to which the user equipment belongs.

After receiving the access request message that the user equipment requests to access the wireless network, the mobility management network element may first authenticate the user equipment according to the access request message, and send the subscription data request message to the HSS after the authentication is passed. The HSS is requested to provide group subscription data of the group to which the user equipment belongs.

The subscription data request message carries an identifier of the mobile network element and an identifier of the user equipment, where the identifier of the user equipment is an IMSI (Internal Mobile Subscriber Identity). 211. Receive a subscription data request response message sent by the HSS in response to the subscription data request message. The subscription data request response message carries the subscription data of the user equipment, or the subscription data of the user equipment and the group subscription data of the group to which the user equipment belongs.

When one or some user equipments in the group have accessed the wireless network, the group management subscription data is saved in the mobility management network element. For the same group, only one copy of the group subscription data is saved in the mobility management network element. At this time, the subscription data request response message returned by the HSS does not need to carry the group subscription data, and only needs to save the subscription data of the user equipment.

When no user equipment in the group accesses the wireless network, the group subscription data is not saved in the mobility management network element. At this time, the subscription data request response message returned by the HSS carries the subscription data of the user equipment and the group subscription data of the group to which the user equipment belongs.

212. Acquire a group policy control information of the group according to the subscription data request response message. And if the subscription data request response message carries the subscription data and the group subscription data of the user equipment, the group subscription data is directly obtained from the subscription data request response message.

If the subscription data request response message only carries the subscription data of the user equipment, first obtain the group identifier of the group to which the user equipment belongs from the subscription data of the user equipment, and then move from the mobile group according to the group identifier. The management network element searches for the group subscription data corresponding to the group identifier, and finally, obtains the group policy control information from the group subscription data.

After the step 102 is performed, in step 103, the access request message of the user equipment is responded according to the group policy control information.

In a possible implementation manner of the present application, as shown in FIG. 2b, step 103 includes the following steps:

221, determining whether the received access request message meets a preset condition, if the preset condition is met, performing step 222; if the preset condition is not met, performing step 223;

Specifically, if the access request message sent by the user equipment indicates that the access request message is an access request initiated in response to the paging, the mobility management network element does not perform a group policy of the group to which the user equipment belongs to the user equipment.

After receiving the access request message of the user equipment, the mobility management network element performs a group policy of the group to which the user equipment belongs.

In a specific implementation, according to the group policy control information obtained in step 213, it is determined whether the related information of the access request message sent by the user equipment meets the group policy control information.

In a specific implementation, if the group policy control information includes a preset time range in which the group allows the user equipment to access the wireless network, determine whether the time information of the access request message sent by the user equipment is in the preset time range. In the range;

If the group policy control information includes a preset number range of the user equipment that the group allows to access the wireless network at the same time, determine whether the quantity information of the user equipment requesting to access the wireless network in the same time period in the group is in the foregoing Within the range of quantities;

If the group policy control information includes a preset number of bearers that the group is allowed to allocate to the user equipment, it is determined whether the number of bearers allocated by the group to the user equipment that has accessed the wireless network is within a preset number of bearers.

It should be noted that the group policy control information may include a preset time range in which the group allows the user equipment to access the wireless network, a preset number range of the user equipment that the group allows simultaneous access to the wireless network, and a group allowed to be the user equipment. And at least one of the preset bearer number ranges of the bearer, when the group policy control information includes the foregoing multiple control policies, when the related information of all the access request messages meets all the control policies, accepting the access of the user equipment Request message.

222. Accept an access request message of the user equipment of the group.

After the related information of the access request message sent by the user equipment meets the preset condition, the mobility management network element receives the access request message, and continues to perform a subsequent processing procedure, so that the user equipment accesses the wireless network.

The subsequent processing procedure is related to a specific request type of the access request message sent by the user equipment. For example, if the access request message sent by the user equipment is an attach request message, the subsequent processing flow is a process of authentication, location update, bearer establishment, and the like;

If the access request message sent by the user equipment is a PDN Connectivity Request (PDN Connectivity Request) message, the subsequent processing flow is a process such as a Create Session process and a Bearer Setup process.

After the subsequent process corresponding to the access request message is completed, the mobility management network element returns an access request response message for allowing the user equipment to access the wireless network to the user equipment.

223. Reject the access request message of the user equipment.

In a specific implementation, the mobility management network element may return an access request response message that denies the user equipment access to the wireless network by returning to the user equipment.

The access request response message may include an Attach Reject message, a Routing Area Update Reject message, a Tracking Area Update Reject message, a Service Request Reject message, PDN Connectivity Reject message, Active PDP Context Reject message, Bearer Resource Modification Reject message, or Modify packet data Modify Packet Data Protocol Context Reject message, etc.

The group access control wireless network control method provided in this embodiment firstly stores the group policy control information of the group in the HSS. When the user equipment in the group accesses the wireless network, the mobility management network element acquires from the HSS. The group policy control information of the group controls the state of the user equipment connected to the wireless network in the group according to the group policy control information. Therefore, the state in which the user equipment in the group accesses the wireless network is controlled according to the access requirements of different groups. In turn, the group manager can individually control the access situation of the group according to his own needs. In addition, different access control policies are implemented for different groups, so that the wireless network can individually control the time range of a group to access the wireless network and the network resources used, thereby avoiding a large increase when a group accesses the wireless network. The wireless network load affects the access of the user equipment in other groups to the wireless network, thereby improving the utilization of network resources.

If the group policy control information includes a preset time range for allowing the user equipment to access the wireless network, the flow of the control method of the group accessing the wireless network is as shown in FIG. 3, and the method in this embodiment is applied to the mobile management network element. The method includes the following steps:

301. Receive an access request message sent by a user equipment in the group.

The group policy control information of the group is obtained according to the access request message, where the group policy control information includes a preset time range in which the group allows the user equipment to access the wireless network.

303. Determine whether a time at which the access request message sent by the user equipment is received is within the preset time range. If the time is within the preset time range, perform step 304; if not within the preset time range, Go to step 305. ;

304. Return an access request message that allows access to the user equipment.
