In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It is to be understood that the described embodiments are a part of the embodiments of the invention, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In all embodiments of the present invention, the first network may be a 3GPP network, and the second network may be a Non-3GPP network. For example, the first network may be an LTE network and the second network is a WLAN network. Further, the first network and the second network in all embodiments of the present invention may also be any two different access system networks, for example, an LTE network, a WLAN network, a (Universal Mobile Telecommunications System, UMTS) network, and a global mobile. Global System of Mobile communication (GSM) network, Wideband Code Division Multiple Access (WCDMA) network, Code Division Multiple Access (CDMA) network, etc. FIG. 1 is a schematic flowchart of an access control method according to an embodiment of the present invention. The embodiment of the present invention includes the following content.

The first network determines the first network management information according to the load condition of the first network, the priority of the second network, the signal coverage quality of the second network to the user equipment, or the service type supported by the second network, where the first network management information is determined. The network management information is used to indicate that the user equipment is to disable the first access function, and the first access function is a function that the user equipment accesses the second network.

In 110, the first network may determine the first according to a load condition of the first network, a priority of the second network, a signal coverage quality of the second network to the user equipment, and a service type supported by the second network. Network management information.

120. The first network sends the first network management information to the user equipment, to indicate that the user equipment turns off the first access function according to the first network management information.

In the embodiment of the present invention, the first network is a current serving network of the user equipment; the second network is a target service network of the user equipment, and the second network has different connections with the first network. Enter the system. If the load of the first network does not exceed the threshold set by the system, it indicates that the first network can ensure the quality of service of the user equipment in the first network, so that the user equipment does not need to access the second network. Traffic in a network is offloaded. Therefore, the first access function of the user equipment can be disabled, and the second network is not accessed, thereby saving energy consumption of the user equipment. The threshold set by the system can be preset in the first network according to engineering experience, or can be issued by the network management system.

Optionally, the load condition of the first network may be determined according to the number of user accesses in the first network and the available throughput of the system in the first network. The more the number of user accesses of the first network, the heavier the load of the first network; the less the system available throughput of the first network, the heavier the load of the first network.

As an example, when the number of user accesses in the first network is not greater than the first threshold, the first network may ensure the service quality of the user equipment that has accessed the first network, and the user equipment may not access the second network. The first network performs traffic diversion. Therefore, the first network may determine the first network management information, that is, the user equipment is instructed to disable the first access function, and is not connected to the second network, so that the user equipment may be energy-saving.

As another example, when the available throughput of the system in the first network is not less than the second threshold, the first network may ensure the service quality of the user equipment that has accessed the first network, and the user equipment may not access the second network. Traffic off the first network. Therefore, the first network may determine the foregoing first network management information, that is, the user equipment is instructed to disable the first access function and not access to the second network, so that the user equipment may be energy-saving.

Optionally, the first network may determine the first network management information according to the priority of the second network. When the priority of the second network is less than the third threshold, it indicates that the user equipment cannot or does not want to access the second network to perform service offloading on the first network, or indicates that the first network cannot use the user according to the policy of the network operation. The device accesses the second network, so that the first network may determine the first network management information to indicate that the user equipment turns off the first access function, thereby saving energy to the user equipment.

As an example, the priority of the second network may also change with time. In this case, the first network may indicate that the priority of the second network is small by using the first network management information. The first access function is closed when the third threshold is closed, and the first access function is opened when the priority of the second network is higher than the third threshold by the second network management information.

Optionally, the first network may determine the first network management information according to the signal coverage quality of the user equipment by the second network. When the signal coverage quality of the user equipment of the second network is less than the fourth threshold, the signal coverage quality of the user equipment of the second network cannot meet the service quality requirement of the user equipment, and the user equipment cannot access the second network for service offloading. The first network may determine the first network management information, and send the first network management information to the user equipment, to indicate that the user equipment turns off the first access function, so that the user equipment is saved.

As an example, after the network is deployed, the first network and the second network are fixed in geographic location. The first network may determine, according to the geographic location of the user equipment that accesses the first network, whether the user equipment is located in the second network. If the first network determines that the user equipment is not located in the second network (that is, the second network can be considered as having no signal coverage for the user equipment), the first network may determine that the coverage quality of the second network to the user equipment is less than the fourth threshold. That is, the coverage quality of the user equipment of the second network cannot meet the service quality requirement of the user equipment, so that the first network can determine the first network management information, and send the first network management information to the user equipment, so that the user equipment is The first network management information is used to disable the first access function and is not connected to the second network, thereby saving energy to the user equipment.

As another example, the second network may not be the reference signal measurement result of the second network to the user equipment. The reference signal measurement result obtained by the user equipment to measure the reference signal received power or the reference signal reception quality of the second network is sent to the first network. If the reference signal measurement result is less than the fourth threshold, the signal coverage quality of the user equipment of the second network cannot meet the service quality requirement of the user equipment; the first network may determine the first network management information, to indicate that the user equipment turns off the first access. The function does not access the second network, thereby saving energy for the user equipment. As another example, the second network-to-user equipment signal coverage quality may be determined by the path loss of the user equipment to the second network. The larger the path loss of the user equipment to the second network, the worse the coverage quality of the second network to the user equipment signal. The first network can pass The existing path loss estimation algorithm calculates the path loss of the user equipment to the second network, and determines whether the path loss of the user equipment to the second network satisfies the path loss condition of accessing the second network; if satisfied, If the signal coverage quality of the user equipment of the second network is less than the fourth threshold, the signal coverage quality of the user equipment of the second network cannot meet the service quality requirement of the user equipment, and the first network may determine the first network management information to indicate the user. The device disables the first access function and does not access the second network.

As an example, during the movement of the user equipment, the user equipment may move to a coverage area of multiple networks, and the signal coverage quality of each network to the user equipment is usually different, and the first network may be according to the second network pair. The signal coverage quality of the user equipment determines the start time or shutdown time of the first access function. If the signal coverage quality of the second network is good, the first network may indicate that the user equipment starts the first access function at a certain moment by using the first network management information, and then accesses the second network for offloading. If the signal coverage quality of the second network is degraded, even if the user equipment can access the second network for offloading but the user equipment experience is not good, the first network may indicate that the user equipment is turned off at a certain moment by using the first network management information. The first access function, thereby disconnecting from the second network, and saving energy to the user equipment.

Optionally, if the load of the first network is too heavy, the user equipment may be instructed to start the first access function at a certain time or time period and access the second network. If the load condition of the first network can ensure the experience of the user equipment, the user equipment does not need to initiate the first access function to access the second network, and the first network may indicate, by using the first network management information, that the user equipment is at a certain time. The first access function is turned off at the time or time period.

Optionally, when the service type supported by the second network does not include the type of the service initiated by the user equipment, the first network may determine the first network management information, to indicate that the user equipment turns off the first access function, and does not access the In the second network, the user equipment is saved.

As an example, the first network discovers that the user equipment is in the high-definition video service, and the high-definition video service is not included in the type of the service supported by the second network, and the first network may instruct the user equipment to disable the first access function, and never Access the second network and save energy to the user equipment.

In the embodiment of the present invention, the first network management information may be used to indicate that the user equipment is turned off first. The access function may specifically include:

The first network management information may be used to indicate when the user equipment turns off the first access function. The time when the first access function is disabled may be closed at a certain time or a certain period of time, for example, indicating that the user equipment turns off the first access function during the period from tl to t1 + L*Tl, where tl is The user equipment turns off the start time of the first access function, L is any positive integer, and T1 is the period in which the first access function is closed.

As an optional implementation, the first network may obtain the authorization information of the user equipment, where the authorization information is used to indicate whether the user equipment accepts the indication of the first network management information, and the user equipment receives the indication of the first network management information. The first network determines the first network management information. The first network can manage the user equipments that receive the indication of the first network management information in the first network by acquiring the authorization information of the user equipment, so as to implement energy-saving management of the user equipments. Specifically, the first network may obtain the authorization information by receiving from the user equipment, or by the contract equipment information saved by the core network device when the user equipment accesses the first network. For example, the first access device in the first network may receive authorization information of the user equipment from the user equipment, the core network device, or the centralized control node. The centralized control node in the first network may receive the authorization information of the user equipment from the user equipment or the core network device, and send the authorization information to the first access device.

120. The first network sends the first network management information to the user equipment.

Optionally, the first network may send the first network management information to the user equipment by using Radio Resource Control (RRC) signaling.

130. The user equipment receives the first network management information sent by the first network, and closes the first access function according to the indication of the first network management information.

Optionally, the foregoing method provided by the embodiment of the present invention may further include:

The number of user accesses in the first network is greater than the first threshold, the available throughput of the system in the first network is less than the second threshold, and the priority of the second network is greater than the third threshold, and the signal coverage quality of the second network to the user equipment is not less than When the service type supported by the second network includes the type of the service initiated by the user equipment, the first network may determine the second network management information, where the second network is configured. The information is used to indicate that the user equipment is enabled to enable the first access function. The first network may send the second network information to the user equipment, so that the user equipment starts the first access function according to the second network management information. Optionally, the second network management information may specifically indicate a time or a time period when the user equipment starts the first access function.

In the embodiment of the present invention, the first threshold, the second threshold, the third threshold, and the fourth threshold may be configured by the network management information system and sent to the first network, or may be preset in the first network.

Optionally, in the embodiment of the present invention, the foregoing method further includes:

The first network is determined according to the number of user accesses of the first network, the available throughput of the system in the first network, the priority of the third network, the signal coverage quality of the third network to the user equipment, or the service type supported by the third network. The third network management information, where the third network management information is used to indicate that the user equipment turns off or turns on the second access function, and the second access function is a function that the user equipment accesses the third network, and the third network a target service network having the same access system as the second network; the first network may send the third network management information to the user equipment, so that the user equipment turns off or enables the second access function according to the third network management information. .

The determining process of the third network management information is similar to the determining process of the first network management information and the second network management information, and details are not described herein again.

In the embodiment of the present invention, the method performed by the first network may be performed by the first device in the first network, where the first device may be the first access device or the centralized control node, and details are not described herein. .

The centralized control node in the embodiment of the present invention is a coordination entity for coordinating a plurality of radio access technologies (RATs). For example, the coordinating entity can be used for interference coordination or load balancing of each RAT. Specifically, the centralized control node, for example, a Single Radio Controller (SRC), can control resource scheduling between respective base stations in the communication network, or resource scheduling between the base station and the user equipment.

Applying the technical solution provided by the embodiment of the present invention, the user equipment is controlled to be closed by the current service network. Or, the function of accessing the target service network is turned on, and the function of the user equipment for accessing the target service network is not required to be constantly searched for the target service network, so that the power of the user equipment can be saved. FIG. 2 is a schematic flowchart diagram of a communication method for access control according to an embodiment of the present invention. In this embodiment, the first network is an LTE network, and the second network is a WLAN network. The first access device in the first network is a macro eNB, and the second access device in the second network is a WLAN AP, and the macro eNB and the WLAN AP have different access systems. The eNB is the current serving base station of the UE, and the WLAN AP is deployed in the service hotspot area or the coverage vulnerability area in the coverage of the macro eNB. This embodiment includes the following.

210, as the UE moves within the coverage of the macro eNB, the macro eNB according to the load condition of the macro eNB, the priority of the WLAN AP, the signal coverage quality of the WLAN AP to the user equipment, or the service type supported by the WLAN AP, etc. Determine the first network management information.

In 210, the macro eNB may determine the first network management information according to the load condition of the macro eNB, the priority of the WLAN AP, the signal coverage quality of the WLAN AP to the user equipment, and the service type supported by the WLAN AP. .

As an example, if the load of the macro _e NB does not exceed the threshold set by the system, it indicates that the macro eNB can currently ensure the quality of service of the user equipment of the macro eNB, so that the user equipment does not need to access the WLAN AP. The traffic in the macro eNB is offloaded. In this case, the macro eNB may determine the first network management information to instruct the user equipment to turn off the first access function. In this example, the threshold set by the system may be preset in the macro eNB according to engineering experience, or may be sent to the macro eNB by the network management system. Specifically, the load condition of the eNB may be determined according to the number of user accesses accessing the macro eNB and the available throughput of the macro eNB. The more the number of user accesses of the macro eNB, the heavier the load of the macro eNB; the less the system available throughput of the macro eNB, the heavier the load of the macro eNB.

As an example, the macro eNB may determine the first network management information according to the priority of the WLAN AP. The priority of the WLAN AP may be based on the user equipment according to the user equipment. The setting of the system, the service type, and the like may be preset in the macro eNB, or may be sent by the network management system to the macro eNB. The priority of the WLAN AP indicates that the user equipment cannot or does not want to access the WLAN AP, and the priority of the WLAN AP indicates that the macro eNB cannot access the user equipment according to its own network operation policy. In the WLAN AP, the macro eNB may determine the first network management information to indicate that the user equipment turns off the first access function, thereby saving energy to the user equipment.

Optionally, the macro eNB may determine the first network management information according to the signal coverage quality of the user equipment by the WLAN AP. When the WLAN AP does not meet the service quality requirements of the user equipment, the user equipment cannot access the WLAN AP for service offload.

As an example, since the location of the macro eNB and the WLAN AP is determined during the deployment phase of the network, the macro eNB may determine whether the UE moves to the signal coverage of the WLAN AP by using the location information of the UE, thereby determining whether the UE can be connected. Enter the WLAN AP. As another example, the macro eNB may also calculate whether the UE moves into the coverage of the WLAN AP and access the WLAN AP through the existing path loss estimation algorithm. For example, if the path loss of the UE to the WLAN AP is less than the path loss threshold, the UE is located in the signal coverage of the WLAN AP, and can be connected to the WLAN AP to perform traffic offloading to the macro eNB. If the path loss of the UE to the WLAN AP is not less than the path loss threshold, the UE is not located in the signal coverage area of the WLAN AP, and the UE cannot access the WLAN AP. Therefore, the macro eNB indicates that the user equipment is closed. Into the function, and save power to the user equipment.

Optionally, when the service type supported by the WLAN AP does not include the type of the service initiated by the user equipment, the macro eNB may determine the first network management information, to indicate that the user equipment turns off the first access function, and does not access the WLAN AP. Medium, thereby saving energy to the user equipment.

220. The macro eNB sends the first network management information to the user equipment.

230. The user equipment turns off the first access function according to the received first network management information, and performs power saving.

Optionally, before 210, the macro eNB may acquire authorization information of the UE, where the authorization information is used. Instructing the UE to accept the macro eNB access control; if the UE accepts the macro eNB access control, the macro eNB determines the first network management information, thereby instructing the UE to disable the first access function.

As an optional implementation manner, the macro eNB acquiring the authorization information of the UE may include: when the UE attaches (ATTACH) to the LTE network, the Mobility Management Entity (MME) in the core network device may be from the home subscriber server. (Home Subscriber Server, HSS) acquires contract information of the user equipment, and the contract information includes the authorization information of the UE. The MME saves the UE's authorization information in the context of the UE. When the UE transitions from the idle state to the connected state, the MME forwards the context of the UE to the macro eNB. As another alternative implementation manner, the macro eNB acquires the authorization information of the UE, which may include: after the UE attaches to the LTE network, the macro The eNB receives the authorization information of the UE sent by the UE. For example, when the user equipment is in the connected state in the LTE network, the user equipment may transmit the authorization information of the UE to the macro eNB through the wireless capability information, or the user equipment may carry the UE through the network capability information when the user equipment is in the idle state in the LTE network. The authorization information is sent to the MME; and then sent by the MME to the eNB, for example, adding a field indication to the eNB in the establishment of the context or the modification message of the context. Alternatively, the macro eNB obtains authorization information of the UE forwarded from the centralized control node (the centralized control node is used to schedule the macro eNB and the WLAN AP). For example, after the UE is attached to the LTE network, the centralized control node may obtain the authorization information of the UE from the core network device, and send the authorization information of the UE to the macro eNB.

Applying the technical solution provided by the embodiment of the present invention, the current service network controls the user equipment to disable the function of accessing the target service network, and does not require the user equipment to always start the function for accessing the target service network to continuously search for the target service. The network can save power of the user equipment.
