In the embodiment of the present invention, after the UE successfully accesses the access network device, if the UE needs to send the first data, the UE may add the first identifier to the first data, that is, the UE adds the first number. Converted to the first data block. The first data block may include the first data and the first identifier, where the first identifier may be used to indicate a type of the first data, for example, the first identifier may be used to indicate that the type of the first data is NA The S message is also user data.

In S 2 0 1 , U E converts the first data into the first data block, and may adopt any one of the following methods:

(1) If there is an idle bit in the data header of the first data, the UE may select one or several idle bits as the first identification bit among the idle bits, and set in the first identification bit. A value is used to indicate whether the type of the first data is a NA S message or a user data. Finally, the UE further encapsulates the first data set with the first identification bit into a first data block.

(2) If there is no idle bit in the data header of the first data, the UE may add one or several bits in the data header of the first data as the first identification bit, and in the first identification bit A value is set to indicate whether the type of the first data is a NAS message or a user data. Finally, the UE further encapsulates the first data set with the first identification bit into a first data block.

The type used to indicate the first data is user data, and the bit Q is set in the bit A to indicate that the type of the first data is a NA S message. Specifically, the number of bits used to indicate the type of the first data and the value setting of the bit may be designed according to actual design requirements, and the present invention is not limited.

Specifically, the access network device receives the first data block sent by the UE on the radio bearer. After the access network device parses the first data block, the first data and the first identifier are obtained from the first data block. For example, if the structure of the first data block as shown in FIG. 3 is adopted, the access network device may parse the first data block, acquire the first data, and read the fixed data in the data header of the first data. The bit acquires the first identity.

It should be noted that, for the fixed bit in the foregoing first data, the UE and the access network device are pre-configured to indicate one or several bit positions of the type of the first data.

Further, before the UE sends the first data to the access network device, the UE adds a first identifier to the first data, that is, the UE converts the first data into the first data block, so that the access network device can identify the UE. A type of first data transmitted on a radio bearer, and transmitting the first data to a core network device capable of responding to the type of data, thereby completing normal data transmission.

Therefore, the access network device can consider that the first data is a NAS message according to the first identifier, and the access network device can send the first data to the MME, and the MME responds to the first data. If the first data is the user data, the UE may add a first identifier to the first data when the first data is transmitted to the access network device, to indicate that the type of the first data is user data, so that the access network device According to the first identifier, the first data is considered to be one user data, and the access network device may send the first data to the SGW, and the SGW responds to the first data. For the description of the MME and the SGW, refer to the descriptions of the MME and the SGW in the embodiment shown in FIG. 1 , and details are not described herein again.
