Description
Technical field
The present invention relates to communication field, relate in particular to a kind of to access terminal and access network between the method that detects of service link.
Background technology
In Cdma2000 1xEV-DO (CDMA 2000 enhancing transfer of data) system, when AT (accessing terminal) need carry out transfer of data, just the data of eating dishes without rice or wine between foundation and the AN (access network) connect, Traffic Channel between foundation and the AN, AN is this traffic channel assignments resource, then, AT and AN utilize the resource of distributing to carry out transfer of data mutually on the Traffic Channel of setting up.
When reasons such as wireless environment, cause AT that call drop has taken place owing to various complexity.If AN this moment does not detect AT call drop, still keep data to be connected, and still be this AT Resources allocation with this AT, will cause the resource of AN to waste.Therefore, how to guarantee that the service link state that AN can in time detect AT is a problem demanding prompt solution.
The method of the state of the service link in the prior art between a kind of AT of detection and the AN is: utilize KeepAliveRequest that session layer provides in the Cdma2000 1xEV-DO system (activating the request of detection) and KeepAliveResponse (activate and detect response) message to carry out session activation and detect, the result who detects according to this session activation determines that service link activates the result who detects.Utilize KeepAliveRequest and KeepAliveResponse message to carry out flow process that service link activate to detect as shown in Figure 1, the specific implementation principle is:
According to the agreement regulation, KeepAliveRequest and KeepAliveResponse message can transmit on control channel, access channel, reverse traffic channel, forward traffic channel.
The data flow that AT on the AN monitor reverse sends over, simultaneously, AT monitors the data flow that the AN on the forward channel sends over.The setting-up time value is T
SMPClose/ N
SMPKeepAliveIf AN or AT do not detect any data flow from the other side within the time value of this setting, AN or AT then send KeepAliveRequest message to the other side on forward channel or backward channel, then, wait for the KeepAliveResponse message that the other side responds.Here, T
SMPCloseBe the negotiation attribute of session layer, default value is 54 hours.N
SMPKeepAliveBe the session layer constant, default value is 3.
If AN or AT do not receive the KeepAliveResponse message that the other side responds in the time value of this setting, then AN or AT continue to send KeepAliveRequest message to the other side on forward channel or backward channel.
If AN or AT are after having sent three KeepAliveRequest message to the other side, still do not receive the KeepAliveResponse message that the other side responds, conversation between AN and the AT then is described, so, AT closes the data of eating dishes without rice or wine and connects, deactivates address administration, deactivation session configuration, discharges session, and AT is moved to non-activated state; Perhaps, AN closes the data of eating dishes without rice or wine and connects, deactivates address administration, deactivation session configuration, discharges session, and AN is moved to AMP (address administration agreement) and set up state.
If AN or AT illustrate then that having sent once to the other side, after secondary or three the KeepAliveRequest message, in the time of setting, having received the KeepAliveResponse message that the other side responds the session between AN and the AT is normal.
According to the result that the session activation that carries out on the above-mentioned Traffic Channel between AN and AT detects, determine the state of the service link between AN and the AT.Promptly when the conversation between AN and the AT, then the service link between AN and the AT also interrupts; Promptly when the session between AN and the AT just often, then the service link between AN and the AT is also normal.
The shortcoming of the method for the state of the service link between above-mentioned detection AT of the prior art and the AN is:
1, detection has different characteristics with session activation because service link activates detection, and it is higher that the service link activation detects the real-time requirement that detects than session activation, need detect the AT call drop in a short period of time, and therefore, unification is according to T
SMPClose/ N
SMPKeepAliveBe inappropriate the blanking time of determining detection usefulness.
2, in some practical applications, the AT of part brand receives that AN does not respond KeepAliveResponse message to AN after the KeepAliveRequest message that sends on the forward channel, therefore, will cause AN that the mistake that Traffic Channel activates test is surveyed, discharge normal professional the connection.
