In step S306, the message determining module 106 determines, according to the received response message, whether the base station 20 is allowed to establish a service flow in the current state. In this embodiment, the message determining module 106 determines whether the base station 20 is allowed to establish a service flow by reading the content of the response message. When the DSA-RSP message is the permission information, it indicates that the base station 20 can process the information about establishing the service flow proposed by the user terminal device 10 in the current state. Otherwise, when the DSA-RSP message is rejected, the base station is indicated. 20 cannot be processed in the current state.

In step S308, when the message determining module 106 determines that the base station 20 can process the information about establishing the service flow proposed by the user terminal device 10 in the current state, it sends an acknowledgement message to the base station 20 to indicate that it is ready to send.

The user terminal device of claim 1, wherein the message is The determining module is further configured to not allow the service flow to be established in the current state of the base station, and wait for receiving the delayed response message before the timer expires. The user terminal device of claim 1, wherein the delay message module is further configured to end the request for establishing a service flow when the timer expires and the delay response message has not been received. A base station, configured to establish a service flow with a user terminal device, comprising: a base station receiving module, configured to receive a request message from the user terminal device when the user terminal device needs to establish a service flow, where the request message includes a specific time field for describing the time that the user terminal device can wait; the base station timing module is configured to start a timer according to a specific time field in the request message; the base station determining module is configured to After receiving the request message, determining whether the base station is allowed to establish a service flow in the current state, and determining that the service flow cannot be established in the current state, determining whether the user terminal device can be processed before the timer expires. The request for establishing a service flow; the base station sending module, configured to send a response message to the user terminal device after receiving the request message, to indicate that it allows or denies the user terminal device in the current state a request for establishing a service flow; and a service flow establishing module for processing the user terminal before the timer expires at the base station When the request for establishing a service flow is prepared, the device sends a delayed response message to the user terminal device, where the delayed response message is used to indicate that the base station can receive the service flow; wherein the user terminal device receives the delayed response When the message is received, the feedback confirmation delay message is sent. The base station of claim 6, wherein the base station sending module is further configured to: after receiving the request message, return to the user terminal device The acknowledgment receipt message is used to indicate that the base station has received the request message. The base station of claim 6, wherein the service flow establishing module is further configured to establish a service flow with the user terminal device when the base station allows a service flow to be established in a current state. The base station of claim 6, wherein the base station timing module is further configured to end processing the user when the request for establishing a service flow proposed by the user terminal device cannot be processed before the timer expires. The terminal device establishes a request for a service flow. The base station of claim 6, wherein the base station timing module is further configured to receive the service flow when the confirmation delay message is received before the timer expires, and When the acknowledgement delay message is not received, the request for processing the user terminal device to establish a service flow is ended. A method for establishing a service flow by a user terminal device and a base station, comprising: sending, by the user terminal device, a request message to the base station, where the request is sent to the base station to establish a service flow, where the request message includes a specific time field, Describe the time that the user terminal device can wait, and start the first timer to start timing according to the specific time field in the request message; after receiving the request message, the base station returns an acknowledgement reception to the user terminal device. Transmitting a second timer to start timing according to a specific time field in the received request message; the base station sends a response message to the user terminal device, indicating that the base station allows or denies in the current state a request for establishing a service flow proposed by the user terminal device; the user terminal device determining, according to the received response message, whether the base station is Allowing to establish a service flow; the user terminal device sends an acknowledgement message to the base station to indicate that it has received the response message, and if the base station does not allow the establishment of the service flow, after receiving the acknowledgement message, Determining whether the request for establishing a service flow proposed by the user terminal device can be processed before the second timer expires; if the base station can process the establishment of the service flow proposed by the user terminal device before the second timer expires Requesting, the base station sends a delay response message to the user terminal device to indicate that the base station can receive the service flow; the user terminal device determines whether the delay response report is received before the first timer expires If the delay response message is received before the first timer expires, the user terminal device sends an acknowledgement delay message to the base station, and starts to prepare to send the service flow; and the user terminal device sends the The base station sends traffic. The method for establishing a service flow according to claim 11, further comprising: if the base station allows to establish a service flow, the user terminal sends an acknowledgement message to the base station, indicating that it is ready to send a service flow. Information; and the user terminal device sends service flow information to the base station. The method for establishing a service flow, as described in claim 11, further comprising: if the base station is not allowed to establish a service flow, the user terminal ends the request to establish a service flow when the first timer expires. The method for establishing a service flow, as described in claim 11, further comprising: if the base station determines that the request for establishing a service flow proposed by the user terminal device cannot be processed before the second timer expires, ending Handling the user The terminal device establishes a request for a service flow. The method for establishing a service flow, as described in claim 11, further comprising: when the user terminal device does not receive the delayed response message before the first timer expires, ending the establishment with the base station Service flow request. The method for establishing a service flow, as described in claim 11, further comprising: when the base station does not receive the acknowledgement delay message when the second timer expires, ending processing the establishment of the user terminal device Service flow request.
