BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Dormant processing method and a processing apparatus for the same in a mobile communication network. In particular, the doping processing method and processing apparatus is improved in a method of setting an inactivity timer for transition to a dormant state. It is about.

The doment is a function commonly used in a code division multiple access (CDMA) network for efficient use of radio resources. The mobile station (MS), i.e., a mobile terminal and a base station, has no data packet transmission / reception processing during a period of inactivity. The process of releasing a traffic channel between the controller (BSC).

1 shows a session state between a mobile station (MS) and a base station system (hereinafter, 'fixed station') in the dormant state. As shown in the figure, when the transition to the dormant state, the session between the mobile station (MS) and the base station is terminated, the data packet link 10 is released, the PPP (Point) between the mobile station (MS) and the packet data serving node (PDSN) Only the link 11 is maintained.

As a related art related to a coating function, Korean Patent Laid-Open Publication No. 2004-42436 (a method of processing a packet in a packet data service network) may selectively provide a corresponding coating function to a terminal providing a coating function. A treatment method is disclosed.

By the way, such conventional dome processing technology is configured to determine whether the packet is generated in a constant fixed state of operation time of the inactivity timer to provide a communication service suitable for the traffic trend for each user (User) Has a difficult vulnerability. That is, for example, when downloading a movie file and performing a wireless web surfing, even though the traffic state is different, the operation time of the inactivity timer for determining the transition to the dormant state is always fixed. In contrast, when the inactivity timer is set too short or too long, there is a problem in that service quality is deteriorated due to waste of radio resources or time delay for channel allocation.

More specifically, FIG. 2 illustrates a doping process in an environment in which the operation time I of the inactivity timer is set short regardless of the time interval between the packets P _n and P _{n +1} . In this case, the inactivity timer operation time (I) is relatively short, so that one packet (P _n ) is processed and then transitions to the dopant state quickly, and less radio resources are wasted during the inactivity timer operation time. There is this. However, since the traffic channel (TCH) must be reallocated to process the next packet (P _{n +1} ) after the transition to the doping state, there is a disadvantage in that a time delay as much as the setup interval (A) occurs. If there is not enough radio resources to be reassigned, the service will be terminated.

Meanwhile, FIG. 3 illustrates a doping processing state in an environment in which the operation time I of the inactivity timer is set longer than the time interval between the packets P _n and P _{n +1} . In this case, since there is no setup section A for processing the next packet P _{n + 1} , there is an advantage that rapid data service is possible. However, in this case, the time interval between the packet (P _n, P _{n +1)} time interval and is independent of the packet in relation to that set longer operating time (I) of the inactivity timer (P _n, P _{n +1)} between When relatively large, there is a problem that excessive radio resource waste interval (W) occurs.

The present invention was devised to solve the above problems. In the mobile communication network, a communication service suitable for traffic trends for each user is achieved by appropriately setting an operation time of an inactivity timer in consideration of the time interval between data packets. It is an object of the present invention to provide a coating treatment method and a processing apparatus therefor.

In order to achieve the above object, the doment processing method according to the present invention predicts a time interval between processing one data packet and processing the next packet, and sets an operation time of an inactivity timer according to the prediction value. Thereafter, if there is no packet generation during the operation time of the inactivity timer, the process transitions to the doping state.

It characterized in that it comprises a; setting longer than a predetermined value.

In the step (a), it is preferable to predict the time interval according to the exponential smoothing method expressed by the following equation.

(X _{n +1} : estimated time interval for n + 1 th packet, α: weight, X _n : estimated time interval for n th packet, T _n : actual time interval for n th packet)

In step (b), when it is predicted that the time interval is relatively short, the operation time of the inactivity timer may be set longer than the predicted time interval.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

4 is a view illustrating a process of performing a coating treatment method according to a preferred embodiment of the present invention.

Referring to FIG. 4, first, a process of estimating a time interval until a next data packet is processed after any data packet provided from a corresponding data source is transmitted / received is performed (step S100, step S100). S110).

The time interval prediction between data packets is preferably performed according to a known exponential smoothing method. However, the present invention is not limited to this example, and various methods provided according to general prediction theory may be adopted. Referring to FIG. 5, an equation for predicting a time interval until the next data packet is processed according to an exponential smoothing method may be expressed as Equation 1 below. In Equation 1, X _{n +1} is the estimated time interval for the n + 1 th packet, α is the weight, X _n is the estimated time interval for the n th packet, and T _n is the actual time interval for the n th packet Indicates. Here, α is an empirical value determined by the operator in consideration of the traffic environment, and is determined as a specific value (for example, 0.5, 0.8, etc.) in the range of 0-1.

Referring to Equation 1, after an arbitrary data packet P _n has been processed, the next data packet P _{n +1} is obtained using the time interval X _n and the actual time interval T _n predicted for the processed data packet. We can see that we can calculate the time interval X _{n +1} before processing

After estimating the time interval between the packets in the above manner, a process of comparing the predetermined reference value with the predicted time interval and determining whether the time interval is relatively long or short is performed (step S120).

As a result of the determination, when the time interval is relatively longer than the reference value, the operation time of the inactivity timer is set short (step S130). On the contrary, when the time interval is relatively shorter than the reference value, the operation time of the inactivity timer is set longer (step S135). . In particular, in the latter case, setting the operation time of the inactivity timer longer than the predicted time interval is preferable for the rapid processing of the next packet.

Here, the setting of the inactivity timer operation time may be set long or short based on a predetermined setting value, and the operation time of the inactivity timer corresponding to each packet may be set relatively long or short.

After setting the operation time of the inactivity timer (step S140), the process of determining whether a packet is generated (received) within the operation time is performed (step S150).

If a packet occurs within the operation time of the inactivity timer, the packet is received (step S160), and then the process of step S110 is performed again.

On the other hand, when no packet is generated within the operation time of the inactivity timer, a transition to the dormant state for releasing the traffic channel between the mobile station MS and the base station controller BSC is made (step S165).

In the transition to the dormant state, when the next data packet predicted in step S110 occurs, the inactivity timer is reset and a process of processing the corresponding data packet is performed (step S170).

As described above, the process of predicting the next data packet, setting an inactivity timer, and transitioning to the dormant state is performed each time each data packet is processed, and the subject of such dome processing is a fixed station or a mobile station. Can be.

6 and 7 illustrate a configuration of a coating processing apparatus according to a preferred embodiment of the present invention for performing the coating processing method as described above.

And a doment processor 203 for releasing the traffic channel if possible.

In the present embodiment, the dome processing apparatus 200 is provided inside the base station controller (BSC) 102 or is independently installed outside. In addition, the apparatus to which the dopant processing apparatus 200 is coupled is not limited to the base station controller (BSC) 102, and of course, other apparatuses constituting the fixed station may be applicable.

The configuration of the basic apparatus forming the stationary station is the same as that known in the art. That is, the base station 101 provides a radio interface for signal processing with the mobile station (MS) 100, and the base station controller (BSC) 102 controls the radio link and the wire link and performs functions such as handoff. do. In addition, the packet data serving node (PDSN) 104 is responsible for an interface for packet transmission between networks, and is connected to the exchange 105 through a packet control function (PCF) 103. The exchange 105 matches with the base station controller (BSC) 102 to provide functions such as switching control or call processing of voice calls.

The prediction processing unit 201 performs a process of predicting a time interval after processing of any data packet provided from the data source until the next data packet is processed. Preferably, the prediction processing unit 201 may be configured to predict the time interval according to a known exponential smoothing method, but is not limited to this example and may be configured to perform the prediction operation according to various methods provided according to general prediction theory. Of course it can. When predicting the time interval of the data packet according to the exponential smoothing method, the prediction processing unit 201 is configured to predict the time interval according to the algorithm of Equation 1 described above.

The timer controller 202 sets the operation time of the inactivity timer based on the prediction result of the prediction processor 201. That is, the timer control unit 202 sets the operation time of the inactivity timer to be relatively shorter than the predetermined value when the time interval from the processing of an arbitrary data packet to the processing of the next data packet is longer than a predetermined reference value. By minimizing the waste of radio resources, on the contrary, if the time interval is shorter than the predetermined reference value, the operation time of the inactivity timer is set relatively longer than the predetermined value so that the next packet can be processed quickly. Here, particularly in the latter case, it is preferable to set the operation time of the inactivity timer longer than the predicted time interval.

The doment processing unit 203 transitions to the doping state when no packet is generated within an operation time after the inactivity timer is set by the timer control unit 202, and the mobile station (MS) 100 and the base station controller (BSC) 102 Release the traffic channel between At the transition to the dormant state, the session between the mobile station (MS) 100 and the base station controller (BSC) 102 ends and the link is released, and the mobile station (MS) 100 and the packet data serving node (PDSN) 104 The point-to-point protocol (PPP) link between

In the present embodiment, the doping processing device 200 includes a prediction processing unit 201 for predicting a time interval from when an arbitrary data packet provided from a fixed station is received until the next data packet is processed. A timer controller 202 for setting the operation time of the inactivity timer based on the prediction result, and a dome processing unit 203 for terminating a session between the mobile station (MS) 100 and the fixed station so as to transition to the doping state. Since the main configuration of the doping apparatus 200 is substantially the same as the above-described embodiment, a detailed description thereof will be omitted.

Next, the operation of the coating processing apparatus according to the preferred embodiment of the present invention will be described.

A doment processing apparatus according to a preferred embodiment of the present invention is provided in a fixed station or mobile station (MS) 100 to perform functions such as time interval prediction between data packets, setting an inactivity timer, and doment processing.

In other words, first, the prediction processing unit 201 of the dome processing apparatus predicts the time interval between processing any data packet provided from the data source and processing the next data packet using an algorithm such as exponential smoothing.

Subsequently, the timer control unit 202 of the doping processing unit sets the operation time of the inactivity timer to be relatively short when the time interval until the next packet is processed is set to be relatively short, and conversely, the time interval to be relatively short. If it is predicted, the inactivity timer is set to match the traffic tendency of the user by setting a long operation time of the inactivity timer.

After the inactivity timer is set, the process of driving the inactivity timer to determine whether a packet is generated during an operation time is continued. If no packet is generated within the operation time, the doment processing unit 203 performs a transition to a dormant state releasing a traffic channel between the mobile station (MS) 100 and the base station controller (BSC) 102.

The operation of the dome processing apparatus as described above is performed repeatedly each time each data packet is processed to provide a dome function corresponding to the traffic environment.

Although the present invention has been described above by means of limited embodiments and drawings, the present invention is not limited thereto and will be described below by the person skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims.

According to the present invention, since a dome function corresponding to a traffic trend for each user may be provided, there is an advantage of improving both the utilization efficiency and transmission quality of radio resources.

In other words, if the time interval between the traffic conditions for each user is estimated and the next packet is very long, the inactivity timer can be set shorter to increase the efficiency of radio resources. If the time interval is very short, unnecessary time delay problem can be solved by setting the inactivity timer operation time longer than the packet interval.
