 Step 101: Receive an access request sent by the terminal, where the access request includes indication information indicating whether the terminal needs to perform data transmission.

 When the terminal needs to access the network, the terminal sends an access request to the network side device, which may be a CR message, and adds indication information indicating whether the terminal needs to perform data transmission in the CR message. The indication information can be represented by a specific field or character to enable the network side device to recognize. In this embodiment, whether the terminal needs to perform data transmission includes at least one of the following situations: the terminal needs to send data to the network side device, and the terminal needs to receive at least one of the data sent by the network side device.

 Specifically, when the terminal is currently transmitting data to the network side device or when the terminal is currently receiving data sent by the network side device, it needs to be redirected to another network, normally switched to another network, or when the network is reconnected to the network. It is judged that the terminal currently needs to perform data transmission. If the terminal does not need to perform data transmission and needs to access the network in the above several situations, it is judged that the terminal does not need to perform data transmission.

 Step 102: Determine, according to the access request, whether the terminal allocates resources for transmitting data. When the terminal receives the access request of the user, it determines whether to allocate resources for the terminal according to the indication information in the access request, that is, when the access request includes indication information indicating that the terminal needs to perform data transmission, the terminal allocates the transmission information to the terminal. The resource of the data, otherwise, the terminal is not allocated resources for transmitting data.

 The resources of this embodiment may include air interface resources for transmitting data.

 According to the method for accessing the network according to the embodiment, the network side device can know in advance whether to allocate corresponding transmission data to the terminal by adding an indication message for indicating whether the terminal needs to perform data transmission in the access request sent by the terminal. Resources, so that it is not necessary to allocate resources to terminals that do not have data transmission, to avoid waste of resources, and to ensure normal business.

 When the indication information is that the terminal needs to transmit data, it is determined whether a connection is established between the network side device and the PCF. When the determination result is no, the network side device establishes a connection with the PCF. When the determination result is yes, the network side The device can use an established PCF connection.

 Step 201: When the terminal needs to send an access request to the network side device, it is determined whether the terminal needs to perform data transmission.

 The terminal access network includes the following: The terminal performs network switching in the idle (Idle) state, the terminal is redirected to another network in the activated state, the terminal normally switches to another network in the activated state, and the terminal is dropped. The network reconnects to the network. Specifically, the terminal may be handed over from the LTE network to the CDMA network, the terminal is redirected from the LTE network to the CDMA network, the terminal normally switches from the LTE network to the CDMA network, or the terminal drops from the LTE network and re-accesses the CDMA network.

 The above processes are all prior art and will not be described here.

 When the terminal is currently transmitting data to the network side device or when the terminal is currently receiving data sent by the network side device, the terminal needs to redirect to another network, switch to another network normally, or judge the terminal when the network is reconnected to the network. Currently, data transmission is required. If the terminal does not need to perform data transmission and needs to access the network in the above cases, it is judged that the terminal does not need to perform data transmission.

Step 202: Determine, according to the determination result, whether to indicate whether the terminal is included in the access request. Instructions for data transmission are required.

 When the terminal needs to generate an access request, it may first determine whether it has data to be transmitted, for example, transmitting data to the network side device or receiving data sent by the network side device. The access request may be a CR message, and a field or a character indicating whether the terminal needs to perform data transmission is added to the CR message, so that the network side device can determine whether the terminal needs to be allocated for transmission when receiving the CR message. The resources of the data. The resource includes air interface resources for transmitting data. In addition, when the network side device determines, according to the CR message, that the terminal has data to transmit, it determines whether there is a connection with the packet control function PCF, and when the determination result is no, establishes a connection with the PCF, and when the determination result is yes At the same time, the data transmission is performed by using the connection channel already existing between the PCF and the PCF.

 According to the method for accessing the network according to the embodiment, by adding an indication message for indicating whether data transmission is required in the access request sent by the terminal, the network side device can know in advance whether to allocate the corresponding transmission data to the terminal. Resources, which eliminates the need to allocate resources to terminals that do not have data transmission, avoids waste of resources, and ensures normal services.

For the terminal to carry out data transmission (Data transmission). The terminal informs the HRPD network side device that the HRPD network side device needs to upload data or receive data through the XonRequest message, and the HRPD network side device responds to the XonRequest message and opens the PCF channel, and the terminal performs data transmission. The XonRequest message belongs to the Flow Control protocol.

 As shown in FIG. 3C, in order to redirect the terminal from the LTE network to the HRPD network in the active state, the terminal does not currently need to perform data transmission.

The terminal sends a CR message to the HRPD network side device, where the CR message carries a ValueC value indicating that the terminal does not need to perform data transmission.

The HRPD network side device determines, according to the CR message, that the terminal does not need to perform data transmission, and does not The terminal allocates resources, and sends a reject message to the terminal, where the terminal resides in the HRPD network in an idle state.

 As shown in FIG. 3D, in order to redirect the terminal from the LTE network to the HPRD network in the active state, the terminal currently has data to be transmitted.

 The terminal is currently using the air interface resource of the LTE network device for data transmission in the LTE network, and the LTE network sends a redirection indication to the terminal to redirect the terminal to the HRPD network. The terminal sends a CR message to the HRPD network side device, where the CR message carries a ValueD value indicating that the terminal needs to perform data transmission.

 After receiving the CR message, the HRPD network side device knows that the terminal is currently in an active state and needs to perform data transmission, and allocates a Traffic Channel channel to the terminal for data transmission by the terminal. The terminal informs the HRPD network side device that the HRPD network side device needs to upload data or receive data through the XonRequest message, and the HRPD network side device responds to the XonRequest message and opens the PCF channel.
