Description

Method, system and device for avoiding access terminal monitoring confusion

The present invention relates to mobile communication technologies, and in particular, to a method, system and apparatus for preventing an access terminal from listening to confusion. Background technique

In the current CDMA IX EV-DO air interface version (3GPP2 C.S0024-B), a forward traffic channel Media Access Control (MAC) protocol defines a forward traffic available monitoring process. In the process, the AT (access terminal) receives the QuickConfig message in the Overhead (overhead message) protocol sent by the forward control channel, and implements access terminal interception. The QuickConfig message is defined as shown in Table 1:

L Couril: .127To64Jiidnd d 0 or 1

RPCCo3⁄4mtl27Toi ^: 4 0 or 6

RPCCoimt 127Τοβ4 c.ur nc s of :he i llowitig field:

F i-war-ctTraffk: Valid 1 0Tt>383⁄4 0 or 1

0 - 7 (as ndd) Table 1

The nth occurrence of the ForwardTraffic Valid63ToO field corresponds to the traffic channel established by the resource with the media access control index (Maclndex) value of 64-n.

The nth occurrence of the ForwardTraffic Validl27To64 field corresponds to the traffic channel established using a resource with a Maclndex value of 128-n.

The nth occurrence of the ForwardTraffic Validl30To383 field, when the reverse link MACIndex is odd, corresponding to the traffic channel established by using the resource with the MACIndex value of 130+(nl)/2; when the reverse link MACIndex is even, the corresponding a traffic channel established using a resource having a MACIndex value of 257+n/2;

AT from the QuickConfig message in the ForwardTraffic Valid63ToO ,

In the ForwardTraffic Validl27To64 or ForwardTraffic Validl30To383 domain, the ForwardTraffic Valid field of the MACIndex corresponding to the current connection of the AT itself is retrieved as True (1). If True, the service channel corresponding to the MACIndex is available. If False ( 0 ) indicates that the traffic channel has been released by the access network ( AN ), it is unavailable. When the AT monitors that the traffic channel corresponding to the connection has been released, the traffic channel connection can be closed. Operation.

However, there are the following cases: When there are two ATs of ATI and AT2, the traffic channel established by ATI with MACIndex N has been released by the AN, but the AN allocates the traffic channel for the AT2 with MACIndex N, and the QuickConfig message of the AN. The structure is filled in according to the MACIndex occupancy of the AN side, and it cannot distinguish whether the MACIndex N is occupied by which of the two users. FIG. 1 is a schematic diagram of establishing a traffic channel for multiple terminal reuse resources in the prior art. As shown in FIG. 1 , on the time axis, the AN uses MACIndex N to establish a traffic channel for the ATI at the time T1, and the AN will be the ATI at the time T2. The traffic channel is released. At time T3, the AN uses MACIndex N to establish a traffic channel for AT2. In Figure 1, the time points TA, TB, and TC are the QuickConfig in the Overhead protocol sent by the AN to the AT on the forward control channel. At the time of the information, according to the agreement, the interval for sending the QuickConfig message twice is the transmission channel (CCsynSS) of the Control Channel Synchronous Sleep State capsule, which is called the control channel period. The duration is 256 CDMA slots.

During the period from T1 to T2, the AN allocates a traffic channel for the ATI. After the traffic channel is allocated, in the ForwardTraffic Valid field list of the QuickConfig message, the corresponding value is Tme.

During the period from T2 to T3, the AN has released the allocation of traffic channels for the ATI. At this point in time T3, the AN establishes a traffic channel for AT2. In the ForwardTraffic Valid field list of the QuickConfig message, the corresponding value is also True.

When the ATI does not receive the release message sent by the AN due to the loss of the air interface message or the error frame, etc., and the AN has been released as the service channel of the ATI, the ATI still considers that the traffic channel is in the hold state, and continuously opens the reverse channel and listens. Receiving a forward channel message. Thus, at both time points of TB and TC, ATI and AT2 will find the corresponding ForwardTraffic Valid field in the QuickConfig message as Tme according to the MACIndex assigned to it by the AN. Both ATI and AT2 will continue to be connected open, causing reverse interference.

At present, in order to solve the above problem, the AN can set a timer Timer_LockMACIndex to lock a released MACIndex and not assign the newly released MACIndex to the new user for a period of time, thereby avoiding the conflict of MACIndex usage.

However, the inventors of the present invention have found that if the Timer_LockMACIndex is set too short and less than one CCsynSS time, the above problem still occurs:

If the duration set by Timer_LockMACIndex is less than the time of the AT listening control channel period, the time of the AT listening control channel period is usually 12 control channel periods by default, then the situation may occur as shown in FIG. 2, also on the time axis, T1 time AN. Use MACIndex N to establish a traffic channel for ATI. At time T2, AN releases the ATI traffic channel. At T3. In the meantime, the AN uses MACIndex N to establish a traffic channel for AT2. In Figure 2, the duration of TA~TD is Timer_LockMACIndex, and the length of TA~TE is the duration of the AT listening control channel period. If ATI is in the period of TA~TD, it is not able to demodulate the air interface. Demodulation of the control channel packet, unable to know whether the value of the corresponding ForwardTrafficValid field in the QuickConfig message changes, then the ATI can receive the QuickConfig message after the TD time, and mistakenly believe that its corresponding MACIndex resource still exists according to the QuickConfig message, so Continue to stay connected, causing confusion in the monitor.

If the length of the Timer_LockMACIndex set by the AN is greater than the time of the AT listening control channel period, as shown in FIG. 3, on the time axis, the AN uses the MACIndex N to establish a traffic channel for the ATI, and the AN uses the ATI traffic channel at the time T2. Released, at time T3, ATI releases the traffic channel due to control channel interception failure. At time T4, the AN uses MACIndex N to establish a traffic channel for AT2. In Figure 3, the length of TA~TE is set to the time when the AT monitors the control channel period, and the duration of TA~TD is Timer_LockM ACIndex. „If ATI is in the period of TA~TB, because the air interface is demodulated, etc. The control channel packet is not demodulated, and it is impossible to know whether the value of the corresponding ForwardTrafficValid field in the QuickConfig message has changed. At the TE time point, the ATI will release the connection of the traffic channel by itself because the monitoring control channel times out. The time point is after the TE time point, so after the TD time point, the AN reuses the MACIndex N to establish a traffic channel for the AT2, which will not cause confusion of the MACIndex.

However, since the Timer_LockMACIndex must be greater than the time that the AT listens to the control channel period, the interference confusion can be effectively avoided. This time is 12 control channel periods, which is about 5.12 seconds. If each connection is released, it must wait for 5.12 seconds to reuse it. The MACIndex used in the scenario where the call is busy or overloaded may cause the MACIndex to be insufficiently allocated, and the length of the QuickConfig message will increase to the theoretical maximum length, which increases the message of the control channel and seriously wastes network resources.

The specific embodiments of the present invention are further described in detail below with reference to the drawings and embodiments. Embodiments of the present invention provide a method, system, and apparatus for preventing an access terminal from listening to confusion. The access network sets an appropriate minimum reuse time interval, and then notifies the access terminal of the time interval, where the access terminal is to be minimized. When the QuickConfig message is not received within the re-use interval, the connection is released, thereby shortening the minimum reuse time interval, and the length of the QuickConfig message is shortened correspondingly due to the increase of the resource reuse rate, thereby achieving an improvement in reducing the access confusion of the access terminal. Utilization of network resources.

FIG. 4 is a flowchart of a method for preventing an access terminal from listening to confusion in an embodiment of the present invention. As shown in FIG. 4, the method for preventing an access terminal from listening to confusion is provided in the embodiment of the present invention, where the method includes:

Step S401: The access terminal monitors the control channel after the service channel is established, and receives the quick configuration message sent by the access network according to the control channel period t.

Step S402: When the access terminal does not receive the quick configuration message within the minimum reuse time interval T, the service channel connection is released, where the minimum reuse time interval T is re-enabled by the access network. The waiting time before the service channel is established by other access terminals by using the resources currently used to establish the traffic channel, and t T .

Specifically, after the service channel is established, the AT listens to the synchronous control channel message, and determines whether to maintain the traffic channel connection or release the traffic channel connection according to the QuickConfig message received in each synchronization control channel period, if the AN is in a synchronous control channel cycle. After releasing the traffic channel resources of the AT, the AN should also notify the AT through the QuickConfig message of the overhead message protocol at the starting point of the next synchronous control channel period, the traffic channel of the AT has been released by the AN, and the AT is received and released. After the QuickConfig message of the message, the traffic channel connection is released.

To avoid the situation where the T2 and T3 time points are in a synchronous control channel cycle as shown in Figure 1, the AN cannot reuse the same MACIndex in a synchronous control channel cycle. To this end, it is necessary to define a minimum reuse interval T, which should be at least the length of one synchronous control channel period, and configure the minimum reuse interval T to the AT, and the AT does not need to receive the QuickConfig message when it receives the message. Waiting for 12 synchronous control channel periods to release the traffic channel connection, but after reaching the minimum reuse time interval T, the traffic channel connection is released, so that the AN reaches the minimum reuse time interval T after releasing the traffic channel resources, and then uses the MACIndex again. The access terminal does not cause the access terminal to monitor confusion.

Thus, even if the AT is unable to demodulate the control channel packet due to poor air interface demodulation, etc., it is impossible to know whether the value of the corresponding ForwardTraffic Valid field in the QuickConfig message is changed. If the QuickConfig message is not obtained within the minimum reuse interval T, the AT considers that the connection can be released. If a QuickConfig message is received within the minimum reuse interval T, then the AT still trusts the ForwardTrafficValid field in the message and re-times the minimum reuse interval T.

FIG. 5 is a schematic diagram of establishing a service channel for multiple terminal reuse resources according to an embodiment of the present invention. As shown in FIG. 5, at time T1, the AN establishes a traffic channel for the ATI by using MACIndex N, TA, TB and TC are the time points when the AN sends the QuickConfig message in the Overhead protocol to the AT on the forward control channel, that is, the starting point of the synchronous control channel period. If the AN releases the ATI service channel at time T2, the ATI should be at the TC time. The point receives the QuickConfig message carrying the release information. If the QuickConfig message is received, it can determine that the traffic channel has been released according to the ForwardTrafficValid field therein, and the ATI releases the connection and no longer listens to the control channel. Since the minimum reuse time interval T is set to be the same as the synchronization control channel period length, if the ATI does not normally receive the QuickConfig message at the TC time point, it is considered that the minimum reuse time interval T is exceeded, and the ATI still releases the traffic channel connection, and no longer listens. Control channel. In this way, the AN does not generate the interference of the access terminal by using the MACIndex to establish a traffic channel for other ATs after the TC time. In Figure 5, the AN uses MACIndex N to establish a traffic channel for AT2 at time T3, which does not cause interference confusion of the access terminal.

Of course, T can be set to any value greater than or equal to the synchronization control channel period t according to actual needs. However, in order to reduce resource waste, it is better to set T as an integer multiple of the control channel period t.

Since the AT waits for 12 synchronization control channel cycles to release the connection by default when it does not receive the QuickConfig message, in order to reduce resource waste and reuse resources as much as possible, T is usually set to be less than 12 synchronization control channel periods.

When the network is busy, in order to reduce the waiting time of the access terminal, the T value can be set smaller, and the access network can perform resource reuse according to the minimum reuse time interval T, thereby increasing resource utilization and reducing The waste of resources, when the network is relatively idle, can set the T value to be larger, and thus provide better service for the access terminal that has established the traffic channel.

When setting the minimum reuse interval T or changing the minimum reuse interval T, the access network needs to notify all access terminals in the access network, or only notify known access terminals that support the function. The access network and the access terminal may configure the minimum reuse time interval T by negotiation before the access terminal listens to the control channel. Specifically, an implementation manner is: A minimum time interval attribute of the multiplexed MACIndex may be defined in the air interface protocol, and the value of the minimum reuse time interval T is carried by the attribute. For example, in the Overhead Message Protocol of 3GPP2 C.S0024-B, an attribute of the boosting port: MACIndexReuseInterval. As shown in Table 2, the attribute is defined as follows: Attribute ID: Oxfb;

Attribute: M ACIndexReuselnterval;

Values:

0x00: No restrictions;

0x01 ~ OxFF: Length of M ACIndexReuselnterval, in units of a synchronous control channel cycle interval.

If you set T to 3 times the synchronization control channel period length, you can directly set 0x01 ~ OxFF to 3.

When the AT and the AN perform the session negotiation, the M ACIndexReuselnterval attribute of the defined overhead message is also negotiated. If some access terminals do not support the attribute, the access terminal includes the access network to receive the transmission. After the negotiation request for the value of the minimum reuse interval T, no message is returned, or the default parameter 0x00 is returned, indicating that the interval is not limited. For the access terminal that supports the attribute, after receiving the negotiation request that includes the value of the minimum reuse time interval T sent by the access network, after confirming that the minimum re-use time interval T is successfully configured, the acknowledgment message is returned to the access network.

As shown in FIG. 6, the method for preventing an access terminal from listening to confusion according to an embodiment of the present invention includes the following steps:

Step S601: The access network establishes a traffic channel with the first access terminal by using the first resource, and sends a fast configuration message according to the control channel period t.

Step S602: Determine that the release of the traffic channel resource with the first access terminal reaches a minimum reuse. After the time interval T, the first resource is allowed to establish a traffic channel with the second access terminal, where the first access terminal releases the traffic channel connection when the fast configuration message is not received within the minimum reuse time interval, and t T .
