- the present invention relates to a packet communication network for transmitting and receiving bucket 'data, and more particularly to a packet communication network in mobile communication.
- BACKGROUND ART In general, bucket communication service providers charge a fee for a bucket's service based on the amount of information in the bucket, rather than on the call time according to the connection time. .
- a packet line is always set when intermittently performing low information density communication. In this way, by always setting the line, there is no need to make communication settings each time information is sent and received, and the bucket can be sent and received smoothly at any time when information is generated. There is. However, if a packet line is always set in this way, a part of the resources of the packet network is occupied by the set line. This occupied resource is, for example, a resource for maintaining transmission quality. However, resources in the network that are occupied for setting up packet lines are not charged.
- a packet communication service is provided in mobile communication
- mobility control is required in addition to the above-described bucket delivery processing. That is, a handover process is required, which is a process of following the movement of the mobile station and switching the radio base station that communicates with the mobile station.
- a handover process is required, which is a process of following the movement of the mobile station and switching the radio base station that communicates with the mobile station.
- the resources in the network are allocated to more users and economical communication services are provided, while maximally guaranteeing that the necessary communication speed can be provided when users actually perform data communication. Is also an object of the present invention.
- the present invention solves the above problem by monitoring user traffic after establishing communication settings in resource management in a bucket communication network, and suspending the communication state of the user when a specified monitoring condition is satisfied. By setting the state, at least a part of the resources allocated by the user is released, and when the packet communication is started in the communication hold state, the communication state is restored.
- the communication hold state is a state in which a transmission path resource and a relay node resource in a section having a user 'connection are released, and resources in the section can be used by other users.
- the monitoring condition from the communication state to the communication hold state is that there is no transmission / reception of a user-bucket within a reference time.
- the monitoring is performed by measuring a time during which each user has not transmitted / received a bucket, and transmitting the measured time.
- the setting of the hold state includes receiving the transmitted measured time, and measuring the measured time. By comparing the time with a predetermined reference time, the user is notified that the measured time has exceeded the reference time, and is notified that the measured time has exceeded the reference time, and is instructed to release the resources allocated to the user. Assigned to the user according to the release instruction issued. It can also be done by releasing resources. The release of the resource may change the resource state according to time.
- the status may be assigned preferentially to the user in the hold status.
- the setting of the hold state may further change the reference time.
- the reference time can be changed, for example, by registering and storing a reference time determined for each user, and referring to the reference time stored for each user.
- the user may specify the reference time, or the frequency of using communication for each user may be measured, and the reference time may be calculated and set based on the frequency.
- the usage rate of resources in the network may be constantly monitored, and a reference time may be set according to the usage rate.
- the release of the resource may further include a release control for controlling a release sequence and timing of the resource secured for each user.
- the release control step may be characterized in that release control is performed in a predetermined order and timing.
- the node at the end point of the section in the communication hold state simulates a signal indicating that it is connected, and returns a connection confirmation signal.
- the node at the end point of the section in the communication hold state sends a connection confirmation signal for confirming connection to the communication state side. If the connection of the end node cannot be confirmed by the transmission of the connection confirmation signal, the communication is terminated.
- the return from the communication hold state to the communication state is performed by the ordinary outgoing and incoming calls.
- the order is used.
- a routing table for returning may be stored in the end point node of the section in the communication hold state.
- the packet communication network may be a mobile network.
- the location registration of the mobile station may be performed similarly to the normal standby state.

- FIG. 5 is a configuration diagram of an embodiment of the present invention in a packet communication network. First, a configuration in the network when a bucket is transmitted and received between the user terminal 1 and the communication partner 2 using this bucket communication network will be described.
- the measurement units 13 and 13 ' are the time during which the user terminal 1 is transmitting and receiving buckets. It has a function of measuring the time that has not been performed and transmitting the measured time to the comparison unit 5.
- the measuring units 13 and 13 ' can be placed on nodes of a network that constitutes an arbitrary section in the bucket network. However, it is necessary to set up the system so that the user terminal 1 or the packet transmitted / received from the communication partner 2 can be confirmed while resources are released.
- the comparison unit 5 has a function of storing a reference time. Further, the comparing unit 5 has a function of comparing the time during which no bucket is transmitted or received with the previously stored reference time, based on the data sent from the measuring unit 13 and 13 '. . Further, the comparison unit 5 has a function of notifying the instruction unit 6 that the time during which no packet is transmitted or received exceeds the reference time.
- the instruction unit 6 has a function of instructing the release units 12 of the nodes 7 to 10 to release resources based on the information sent from the comparison unit 5.
- the release unit 12 of each node has a function of releasing resources in the network used by the user based on the instruction issued from the instruction unit 6.
- the instructing unit 6 and the comparing unit 5 are implemented in a node that forms a packet path or another node in the network.
- the measuring units 13 and 13 ' measure the packet transmission / reception status for each user.
- the result is sent to the comparison unit 5.
- the comparison unit 5 compares the time during which no bucket is transmitted / received with the reference time, and if either of the states sent from the measurement unit 13 or 13 'is larger than the reference time, the time As over, the instruction unit 6 sends a resource release instruction to the resource release units 12 of the nodes 7 to 10.
- the resource release unit 12 receiving the instruction releases the resources of the node. If resources in the network are completely released, the next time a packet transmission / reception is requested, communication settings will be made again using the free resources in the network. Therefore, resources should not be completely released, that is, resources must be reserved temporarily so that communication resetting is easier than general users who reset communication using free resources. A new state may be newly provided.
- Fig. 6 shows an example of the configuration of a packet communication network to achieve this. In FIG. 6, a resource management unit 11 is newly provided in addition to the network function of FIG.
- the resource management unit 11 constantly monitors the resource status such as the usage rate of the resources in the network, the usage status, the users used, and the user status. At the same time, the resource management unit 11 measures the time of the resource holding state for each user.
- the measuring units 13 and 13 ' measure the transmission and reception of buckets for each user. The result is sent to the comparison unit 5.
- the comparing unit 5 compares the time during which no packet is transmitted or received with the reference time, and when either of the states sent from the measuring unit 13 or 13 ′ becomes larger than the reference time, Time
- the resource management unit 11 is connected to each node in the network and constantly monitors the resource status. Then, the resource hold time is measured for each user, the measured time is compared with the reference time, and the resource state can be changed according to the time. By having a resource management unit having such a function in the network, resources can be released gradually and communication reconfiguration can be performed effectively.
- FIG. 8 is a state transition diagram of FIG. 7, showing the state of controlling the resources of the network step by step.
- the resource management unit 11 and the comparison unit 5 may be on the same node or on different nodes.
- the force has been described and instructs to measure the Oiteri source hold time and the like in the resource management unit 1 1 in the configuration of FIG. 6?, So the comparator 5 and the instruction unit 6 in configuration of FIG. 5 It can also manage the status of resources according to time by providing various functions.
- a user who wants to use packet communication but has not yet made communication settings requests communication settings in the bucket network and performs communication settings (S32).
- the communication setting differs depending on the network configuration, and the communication setting method does not depend on the embodiment.
- a VIP user when performing communication setting using resources in the network, a VIP user may be provided in addition to a general user. VIP users can reserve resources on the network with priority and make communication settings, and the VIP user releases the communication settings without being affected by the usage status of other users. You can keep it until you do.
- the state changes from the communication setting state (S32) depending on whether the user is a general user or a VIP user. If the user is a VIP user, the resources allocated by the user are fixedly set (resource fixed state: S33). If the user is a general user, the resource is in a packet transfer state (S34).
- the invalidation pending state is measured by the measuring units 13 and 13 '. Then, the result is sent to the comparison unit, and the duration of the invalid hold state is compared with the reference time. When the reference time is exceeded, the result is sent to the resource management unit 11 to be in the common hold reserve state.
- the user who has entered the common pending reserve status (S36) is given the right to use the common pending resource that is commonly used by multiple users. In this state, if this user makes a send / receive request, the user has the right to use the common reserved resources in addition to using the released (empty) resources as the general user. The line can be re-established more reliably than the user.
- a fixed amount of the common reserved resources may be reserved in the network in advance, or may be increased or decreased according to the use status of the resources in the common reserved reserve state as shown below.
- Example 1 Increase the number of common resources when the number of users in the common pending reserve state increases.
- Example 2 When a user in the common reservation reserved state releases a resource in the common reservation reserved state, the common resources are reduced.
- a user who performs little or no communication does not even manage resources, completely releases the reserve, and requests for packet transfer.
- resources may be secured from free resources as in the case of a new user, so that the redundant reserved amount of the common reserved resources may be narrowed down.
- the network operator may simplify resource management, skip the reserve state, and shift directly from the invalidation hold state to the resource release state.
- the resource release state (S 37) is a state that transitions from the invalid pending state (S 35) directly or from the common pending reserve state (S 36) when the reference time is exceeded. It is. In-network resources are completely released and become free resources that can be used by any user thereafter. Next, when there is a transmission / reception request, the line is re-established using the free resources in the network again as in the case of a new user.
- the power to be considered here is a resource allocation method when the number of users who send and receive packets increases and resources in the network become congested.
- Figure 8 shows a situation where resources within a network gradually become congested.
- the common resource is divided into two levels (Level A and Level B).
- Figure 8A shows the case where there are free resources.
- the user when a general user sets up communication using resources in the network, the user basically uses free resources in the network.
