In the embodiments of the present invention, the data distribution method and apparatus of the embodiment of the present invention are described by using other types of networks as WLANs. However, the embodiments of the present invention are not limited thereto. The above-mentioned objects, features, and advantages of the embodiments of the present invention will become more apparent and understood. Give further details. FIG. 1 is a schematic diagram of a first embodiment of a data offloading method according to the present invention. The method may be applied to a network side device, and the method includes:

Step 101: Detect whether the current network condition satisfies the offload requirement, and the offload requirement is a requirement for transmitting data of the terminal that needs to be transmitted in the cellular network through another type of network different from the cellular network.

For example, the WLAN is used as an example for other types of networks, but the embodiment of the present invention is not limited thereto. Detecting whether the current network condition meets the shunting requirements may include:

Detecting whether there is the other type of network covered with the cellular network, and detecting whether a current load of the cellular network exceeds a first load threshold, and detecting other types of network load different from the cellular network Whether it is lower than the second load threshold or the like.

The signals covering the other types of networks and the cellular network are simultaneously covered in the same area. Step 102: Broadcast the offload notification information on the broadcast channel if it is detected that the current network condition satisfies the offload requirement.

The offload notification information is used to indicate that the terminal transmits data of the terminal that needs to be transmitted in the cellular network through another type of network different from the cellular network, where the offload notification message includes: access information of the other type of network, for example When the other type of network is a WLAN, the access information may be a service set identifier (SSID) of the WLAN. The offloading notification information may further include: whether to allow information such as a traffic distribution and a traffic distribution manner. The split notification information may be broadcasted on the broadcast channel as a separate cell broadcast signaling, where the individual cell broadcast signaling may be existing cell broadcast signaling or newly defined cell broadcast signaling. The traffic distribution notification information may also be carried in the existing cell broadcast signaling as part of the cell broadcast signaling. In this case, the traffic distribution notification message needs to be specified in the cell broadcast signaling. Corresponding channel number, the channel number is used to identify the channel; when the cell broadcast signaling is broadcast on the broadcast channel, the broadcast notification information is broadcasted on the broadcast channel.

For example, the offload notification information may be carried in the first cell broadcast signaling, and the channel number for broadcasting the offload notification information is specified in the first cell broadcast signaling; correspondingly, the offloading the offload on the broadcast channel The notification information may include: broadcasting the first cell broadcast signaling on the broadcast channel, where the first cell broadcast signaling carries the offload notification information.

The first and second of the first cell broadcast signaling carrying the offloading notification information and the second cell broadcast signaling carrying the offloading stop information have no practical meaning, and are only used for distinguishing the cell broadcast signaling.

When the cell broadcast signaling is broadcasted on the broadcast channel, the different information carried in the cell broadcast signaling may be broadcasted using different channels, and the information broadcasted on different channels may be the same or different. In the embodiment of the present invention, the offloading notification information may be specified to be sent on a certain channel, and the specific channel used by the offloading notification message may be set autonomously in an actual application, which is not limited herein, and may be determined in advance by the network side device and the terminal. .

The broadcast channel can be set autonomously according to the actual application environment of the method in the embodiment of the present invention, which is not limited herein. For example, when the method in the embodiment of the present invention is applied to a 2G network, the broadcast channel may be: a CBCH (Cell Broadcast CHannel), and when the method in the embodiment of the present invention is applied to a 3G network, The broadcast channel can be: CTCH (Common Traffic CHannel).

In the data offloading method shown in FIG. 1, when the network side device detects that the current network condition meets the shunting requirement, the offloading notification information is broadcasted on the broadcast channel, indicating that the terminal in the cell where the network side device is located needs to be transmitted in the terminal of the cellular network. The data is transmitted through other types of networks different from the cellular network, so that the terminal does not need to request the offloading of the network side device through the application layer message, and the network side device does not need to feed back the processing result of the data offloading to the terminal through the application layer message, thereby reducing the network. Application layer data traffic between the side device and the terminal.

In addition, the network side device does not need to perform the shunting request for each terminal, and determines whether the terminal can perform data shunting and processing, reduces the data processing capacity of the network side device, and improves the data processing speed of the network side device. 2 is a schematic diagram of a second embodiment of a data offloading method according to the present invention, where the method can be applied to a terminal, The method includes:

Step 201: If the offload notification information is detected on the broadcast channel, obtain access information of other types of networks different from the cellular network from the offload notification information;

The broadcast channel used by the terminal to detect the offloading notification information should be the same as the broadcast channel used by the network side device to broadcast the offloading notification information, so that the network side device can cooperate with the terminal to implement the offloading notification information on the network side device and the terminal. Transfer between, and then achieve shunt.

In addition, when the offloading notification information is carried in the cell broadcast signaling, the terminal needs to detect the cell broadcast signaling on the broadcast channel in the step, and obtain the offload notification information according to the channel in the cell broadcast signaling. The channel should also be consistent with the channel used by the network side device to send the offload notification message.

The other type of network different from the cellular network may be a WLAN, and the access information may include an SSID of the WLAN.

Step 202: Enable access to the other types of network functions different from the cellular network, and access the other types of networks different from the cellular network according to the access information.

In the data offloading method shown in FIG. 2, when the terminal detects the offload notification information on the broadcast channel, the terminal obtains access information of other types of networks different from the cellular network from the offload notification information; Other types of network functions of the cellular network accessing the other types of networks different from the cellular network according to the access information, thereby realizing that data of terminals that need to be transmitted in the cellular network pass other types different from the cellular network network transmission. In the entire process, the application layer data is not required to be transmitted between the terminal and the network side device, thereby reducing application layer data traffic between the terminal and the network side device. 3 is a schematic diagram of a third embodiment of a data offloading method according to the present invention, where the method includes:

Step 301: The network side device detects whether the current network condition meets the traffic distribution requirement. If yes, go to step 302. If not, go to step 303.

In this step, the network side device can continuously perform the detection in this step. Preferably, the network side device can periodically detect whether the current network condition meets the shunting requirement according to a preset period. Not limited.

For details about whether the current network condition meets the requirements for the offloading, refer to the related description in step 101, and details are not described herein.

Step 302: The network side device broadcasts the offload notification information on the broadcast channel. Step 304 is performed.

For details about the implementation of this step, refer to the related description in step 102, and details are not described here.

Step 303: The network side device broadcasts the offload stop information on the broadcast channel. Step 304 is performed. The offload stop information is used to instruct the terminal to stop transmitting data of the terminal that needs to be transmitted in the cellular network through other types of networks different from the cellular network;

The other type of network is a WLAN, and the offload stop information is specifically used to: instruct the terminal to stop transmitting data of the terminal that needs to be transmitted in the cellular network through the WL AN.

The split stop information may be broadcasted on the broadcast channel as a separate cell broadcast signaling, where the individual cell broadcast signaling may be existing cell broadcast signaling or newly defined cell broadcast signaling. The traffic off-stop information may also be carried in the existing cell broadcast signaling as part of the cell broadcast signaling. In this case, the traffic off-stop information needs to be specified in the cell broadcast signaling. Channel number; when the cell broadcast signaling is broadcast on the broadcast channel, that is, the paging stop information is broadcasted on the broadcast channel.

For example, the offload stop information may be carried in the second cell broadcast signaling, and the channel number corresponding to the offload stop message is specified in the second cell broadcast signaling; correspondingly, the offload stop message is broadcasted on the broadcast channel. The method may include: broadcasting a second cell broadcast signaling on the broadcast channel, where the second cell broadcast signaling carries the offload stop information.

The specific implementation manner of the offloading notification information and the offloading stop information may be set autonomously in an actual application, and is not limited herein.

Preferably, the offloading notification information and the offloading stop information may include a offloading indication field, where the offloading indication field is used to identify the information as the offloading notification information or the offloading stop information, that is, to indicate whether the terminal performs the offloading. Correspondingly, the offload indication field in the offloading indication information is set to be offloaded by the terminal; and the offloading indication field in the offloading stop information is set to be not offloaded by the terminal. The content of the field in the traffic distribution indication field is used to identify the terminal for offloading. The content of the field is used to identify the terminal not to be offloaded. This is not limited, as long as the content of the field that identifies the terminal for offloading is different from the content of the field that the terminal does not perform offloading. can.

Alternatively, the offloading notification information and the offloading stop information may also not set the offloading indication field, but distinguish the offloading notification information and the offload according to whether the information carries the access information of the other type of network, for example, the SSID of the WLAN network. Stop the message. For example, the SSID field is set in the information, where the field is used to indicate the SSID of the WLAN network, and the SSID field of the offload notification information carries the SSID of the WLAN network, and the field content of the SSID field of the offload stop information may be defaulted. The distinction between the offload notification information and the offload stop information is implemented.

In addition, when the offload notification information and the offload stop information are carried in the cell broadcast short signaling, the offload notification information and the offload stop information may be transmitted through the same channel or through different channels. When the offload notification information and the offload stop information are broadcast through different channels, the offload notification information and the offload stop information may also be It is distinguished by channel, and will not be described here.

Step 304: The terminal detects the offload notification information and the offload stop information on the broadcast channel, and when the offload notification information is detected, step 305 is performed; when the offload stop information is detected, step 306 is performed.

In this step, the terminal may continuously detect the offloading notification information and the offloading stop information on the broadcast channel, or may periodically detect the offloading notification information and the offloading stop information according to the preset period described in step 301, where Not limited.

The other types of networks are different from cellular networks.

For example, the other type of network is a WLAN, and the access information is an SSID. The terminal obtains an SSID of the WLAN network from the offload notification information, and accesses the WLAN network according to the SSID.

When the terminal accesses the WLAN network, the access point of the SSID identifier may be directly searched for accessing the access point; or the searched access point information may be reported to the network side device. The network side device selects an access point to instruct the terminal to access the selected access point.

If yes, disconnects the connection with the other type of network different from the cellular network, and closes the access to the different cellular. Other types of network functions of the network; if not, other types of network functions that are different from the cellular network are not accessed, and other types of networks other than the cellular network are not accessed.

Therefore, the network side device does not need to use the interaction of the application layer data to implement data offloading, and the traffic of the application layer data between the network side device and the terminal is reduced. Further, the network side device only needs to detect whether the current network condition is The shunting request is met, and the corresponding broadcast offloading notification information or the shunting stop information can be obtained. It is not necessary to receive the shunt registration message of each terminal, and each terminal is separately judged and processed whether the shunting request is satisfied, and the processing result of the data shunting is not required. Each terminal is notified separately, thereby reducing the data processing capacity of the network side device and improving the data processing speed of the network side device. 4 is a schematic diagram of a fourth embodiment of a data offloading method according to the present invention, where the method includes:
