Abstract

Providing data services using idle cell capacity in a cellular communications system. The system and method assign priorities to each remote user device in the cellular communications system. In response to a request for service for a remote user device, the mobile switch determines whether an idle channel is available for the remote user device. If no idle channel is available, the mobile switch determines whether a remote user device with a lower priority than the requesting remote user device is using a channel. If a lower priority remote user is using a channel, its call is terminated and the channel is assigned to the requesting remote user device. If no lower priority remote user device is using a channel, the request for service is put into an ordered queue to wait for the next available idle channel.

Description

A SYSTEM AND A METHOD FOR PROVIDING DATA SERVICES USING THE RESOURCES OF UNLOCKED CELLS FIELD OF THE INVENTION This invention relates in general to a communication system of the switched type and, more particularly, to a method for transmitting data using unoccupied resources of the communication system.

BACKGROUND OF THE INVENTION Circuit switched networks, such as cellular communications systems, generally offer only one class of service that is used primarily for voice calls. In a cellular communications system, voice calls compete with the data calls for the same limited number of channels available in a particular cell or network access point. Therefore, service providers can not justify the quotation of data calls in a different way than voice calls, and as a result, cellular communication systems have not been used extensively as data networks. Some service providers have sought to overcome the problem of individual class service by deploying separate facilities to handle data calls on a reduced fee basis. The P1094 / 00MX separate data facilities in a communications system, cellular can still reduce only the cost of data calls to the degree that the capital investment for these facilities is less than the communications systems, cell phones used for voice calls . Consequently, in existing cellular communications systems, the demand for voice call service adjusts the price that a company will charge rationally to compete for the data calling service. European Patent Application 370,826 describes a protocol for simple communication systems, which provides the notification of a subscriber unit that a predetermined allocation of time is expiring. U.S. Patent No. 5,574,977 describes a system and method for providing reserved channels and / or queued positions to priority users during periods of call congestion. The European application number 717,579 describes a system for giving priority to the service to users of the telephone, cellular system.

SUMMARY OF THE INVENTION The present invention offers multilevel service in a communications system, cellular, wireless, as well as in a communications network, switched, wired, by providing a system and method for using unoccupied channels P1094 / 00MX of an existing communications system, cellular, for the transmission of data. By offering several levels of service in unoccupied channels, the service provider can rationally quote the data call service below the quote level of the voice call service while at the same time increasing the use of the cellular communication system. In particular, the system and method of the present invention are based on the fact that many applications of data transmission are not particularly time-sensitive. In contrast, voice calls are time sensitive and require immediate connection connection continuity. A delay in sending email for a few minutes or even a few hours does not substantially reduce the perceived value of the user of the data transmission service. Likewise, an interruption in the sending of electronic mail will not substantially reduce the perceived value of the service. Therefore, data calls, other than voice calls, can expect the availability of an unoccupied channel. By using unoccupied channels for data transmission, the service provider can rationally quote data calls less than higher priority voice calls. The use of unoccupied channel capacity P1094 / 00MX for data calls at a lower price also ensures greater use of the communications system, cell phone . In order to use empty channels for data transmission, the system and method of the present invention assign a priority to each remote user device. The priority of each remote user device is part of the profile and authorization information for each remote user. Priority is associated with the Mobile Identification Number (MIN) for each remote user. The profile and authorization information that includes the priority are kept in a database (home location register (HLR)) on the mobile switch. The mobile switch controls the cellular communication system and provides the computer memory for the present invention. When a call request is received in the mobile switch for the service either from a remote user or to a remote user (first remote user), the mobile switch first verifies the profile and authorization information of the first remote user stored in the base HLR data and determines the priority of the remote user. The mobile switch then finds out if a channel in the cell (or cell sector) where the device of the first remote user is located has a channel P1094 / 00MX unoccupied. If an unoccupied channel is available, the call to or from the device of the first remote user is immediately connected without considering the priority of the device of the first remote user. However, if an unoccupied channel is not available for the connection of the call to or from the device of the first remote user, the mobile switch searches for the cell for a channel that is being used by a remote user device with a priority that is less than the priority of the device of the first remote user. If a lower priority remote user device is not found in an active channel, the call request for the first remote user device can be placed in a queue sorted by priority of other remote users to wait for the availability of an idle channel. When the remote user is placed in the ordered queue, the mobile switch notifies the remote user that it has been queued, so that the remote user will not continue to request the service while the request for the user service is queued. remote. When a channel becomes available, the remote user at the head of the ordered queue then connects. Whether a remote user is placed in the queue or not depends on several factors that include the profile and authorization information in the HRL for the user Remote P1094 / 00MX, if the call is incoming or outgoing, and how the incoming data was handled by the mobile switch. If the remote user has not registered to be queued or if queuing will obstruct other resources, your call request may be terminated when you can not connect quickly. However, if a remote user device of lower priority (second remote user) is in the cell (or cell sector), the mobile switch will terminate the call for the second remote user device and connect the call to the remote device. first remote user on the left channel. If more than one remote user device of lower priority is found in the cell and if both lower priority users have the same priority, the lower priority user with the longest duration of the call will be terminated in favor of the call request for the device of the first remote user. At the end of the call of the second remote user in favor of the first remote user, the data transmission computer program of the second remote user recognizes the termination and stores the parameters that allow the data transmission of the second remote user to be resumed in the where the termination of the transmission occurred. Once the device call of the second remote user has been terminated, a request to P1094 / 00MX resume the call for the device of the second remote user can be placed in the queue ordered by priority to wait for the availability of an unoccupied channel. When the second remote user is placed on the ordered queue, the mobile switch notifies the second remote user so that the second remote user will not attempt to establish the connection until his call request reaches the head of the ordered queue. Notification to the second remote user of the call termination and queuing also gives the second remote user the opportunity to close their data transmission in an orderly manner. When the terminated call of the second remote user reaches the head of the ordered queue and when an unoccupied channel becomes available, the call is resumed at the point where it was terminated. When the call request to the first remote user originates from the communication, switched, public network and is for the transmission of data to the first remote user, the mobile switch retrieves the profile and authorization information for the first remote user from the HRL. If the first remote user is a high priority data user with time sensitive data (such as video data associated with a video conference call), the request will connect based on its priority, and P1094 / 00MX the connection will be maintained for the duration of the call. However, if the first remote user is a low priority data device and if the data is not time sensitive, the mobile switch will store all incoming data from the communication, switched, public network and onnect the call from the communications network, switched, public once the incoming data has been stored. For the incoming caller of the public switched, communication network, the call seems to have been immediately connected and terminated so that no additional call requests are made for the service for that particular incoming call by that caller incoming to the mobile switch. In fact, the data is stored in a buffer in the mobile switch or other central location, and a call request is generated to the first remote user in the mobile switch. If an unoccupied channel is available, the first remote user connects and the data is ributed (transmitted) from the buffer to the first remote user. If an unoccupied channel is not immediately available, the call request for the first remote user is placed in the ordered queue, and the data is ributed (transmitted) from the buffer to the device of the first remote user when the P1094 / 00MX first remote user moves to the head of the ordered queue and when an unoccupied channel becomes available. In another aspect of the present invention, a multi-channel data service is provided by the use of a mixture of priorities. For example, a three-channel data service could be provided for a remote user by assigning a high priority to one of the channels of the remote users and a lower priority to the other two channels. This mix of prioritization allows the remote user to obtain high priority access such as a voice call every time in the high priority channel. During times of least traffic, when unoccupied channels are available for lower priority data, the remote user can achieve performance on all three channels at a rate of approximately three times the voice rate. The system and method of the present invention allows an existing communications, cellular or other communications network, switched system, to establish calls based on the priority assigned to each remote user. A call to or from a remote lower priority user, such as a data call, is connected only after higher priority calls, such as voice calls, are terminated and the calls are made available.

P1094 / 00MX unoccupied channels. By prioritizing and using unoccupied channels for lower priority calls, a service provider can rationally offer lower rates for lower priority calls, and at the same time increase the full utilization of the cellular communications system.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram of a cellular communications system that is an environment for the present invention. Figure 2 is a flow chart illustrating the method for handling requests for the service from a remote user in accordance with the present invention. Figures 3A and 3B are a flow diagram illustrating the method of handling requests for service to a remote user to transmit data to the remote user in accordance with the present invention.

DETAILED DESCRIPTION An environment for the present invention is an existing communications, cellular system. These communications systems, cellular include between .other those constructed and operated according to several well-known standards, such as a TDMA (IS-54 and IS-136), AMPS (IS-41), NAMPS, GSM, DCS1800, P1094 / 00MX DCS1900, CDMA (IS-95), PACS, TACS, JTACS, and PDC. The present invention also has applicability to any other communications network, switched by circuits having a control switch and a node access point controlled with a limited number of channels in each node, such as the digital circuit carrying networks. Returning to the drawings in which similar numbers refer to similar parts or steps in the various figures, in Figure 1 of this specification is a schematic diagram of a cellular communication system 10 which constitutes an environment for the present invention. The cellular communications system 10 comprises a mobile switch 14 and a number of cells, such as the illustrated cell 22. The cellular communications system 10 is connected to the telecommunications system 12, switched, public via the mobile switch 14. Each cell, such as cell 22, has a transmitter / receiver tower 24 that transmits data to and receives data from remote users 26 (mobile unit 1), 28 (mobile unit 2), and 30 (mobile unit 3). Each cell has a limited number of channels in which data can be transmitted and received. While each of the remote users 26, 28 and 30 are illustrated as a car-based telephone user, the P1094 / 00MX remote users can include a variety of devices, such as portable telephones, facsimile machines, computers, telemetry devices and control devices, among others. The mobile switch 14 comprises a buffer 16, a cell controller 18, and a home location register (HLR) 20. The cell controller 18 is a general-purpose, high-speed digital computer that is programmed to control the functions required of the mobile switch 14. The HLR 20 is a memory device "capable of storing a database under the control of the cell controller 18. The database in the HLR 20 includes the profile and authorization information that includes the Priority for each of the remote users The buffer 16 is a memory device under the control of the cell controller 18 which is used to receive and store data for subsequent distribution to a remote user in the cell according to an aspect of the present invention.While the buffer 16 is illustrated within the mobile switch 14, the buffer can be located remotely. communication system 10, cellular, the voice call service requests immediate access to a channel and the continuity of connection on the channel during the duration of the voice call. He P1094 / 00 X voice call service will be considered unacceptable by remote users if a remote user can not acquire a channel quickly and / or if voice calls are lost during a conversation. In contrast, the data call service can not request the same urgency of access or connection continuity. An email message or facsimile document can be delayed for several minutes or even hours without adversely affecting the usefulness of the data calling service. Similarly, the transmission of an e-mail message or a facsimile document may be introduced and then resumed without adversely affecting the service while the resumption may take the transmission at the point of interruption. The present invention provides a system and method for taking advantage of the different priorities required to satisfy voice calls and data calls. In order to provide different service priorities, each remote user device is assigned with a priority based on the nature of use of that remote user device. Each user's priority assignment is associated with the user's mobile identification number (MIN). The priorities associated with the MIN of each user are stored in the HLR database 20 on the mobile switch 14. For example, the P1094 / 00MX mobile phones that provide voice call service, are assigned with the highest priority. On the other hand, wireless facsimile machines and wireless e-mail systems are assigned with a lower priority. While the present invention will be described in conjunction with a system of two priorities, the highest priority for voice and the lowest priority for data, the invention lends itself to multiple priorities. Each lower level of priority offers the opportunity for lower charges by the service provider to customers with low priority needs for data transmission. Conversely, the high priority service rationally brings with it the opportunity to charge more for the service provider. In addition, a remote user device could be assigned with multiple MINs each with a different priority or a mix of priorities. These multiple MIN devices could thus provide, for example, three service channels, one high priority service channel and two additional lower priority data service channels. This device would have high priority access for the data transmission every time and during the moments of lower traffic could use the three channels for the transmission of data of increased speed using all three together P1094 / 00MX channels. Returning to Figure 2, a flowchart showing the method of the present invention is shown when the remote user 26 (mobile unit 1) requests service from within the cell 22. The method of the present invention begins in step 200 with a request for service from the mobile unit 1 in the cell 22. The request for the service is transmitted in a conventional manner to the mobile switch 14. In step 204, the cell controller 18 requests the HLR database 20 determining the service priority for the mobile unit 1 based on the profile and authorization information of the mobile unit 1. The profile and authorization information of the mobile unit 1 were provided to the mobile switch 14 when the mobile unit 1 was registered by first time with the service provider for the communications system 10, cellular. After acquiring the profile and authorization information that includes the priority for the mobile unit 1 of the HLR in step 204, the method proceeds to step 202. In step 202, the cell controller 18 of the mobile switch 14 finds out whether there is an idle channel available to service the service request of the mobile unit 1. If in step 202, the cell controller 18 of the mobile switch 14 P1094 / 00MX determines that there is an unoccupied channel in cell 22, the method follows the branch "yes" to step 216, and the unoccupied channel is assigned to mobile unit 1 without considering the priority of mobile unit 1. When the call of the mobile unit 1 is terminated, the method proceeds to step 222 where the complete call is terminated for the mobile unit 1. On the other hand, if there is no idle channel available in step 202, the method follows the branch "no" from step 202 to step 206. In step 206, the method determines whether there is a current remote user in cell 22 that has a lower priority than the priority of mobile unit 1. If all users have a priority equal to or greater than the priority of the mobile unit 1, the method follows the "no" branch to step 220. In step 220, based on the profile and authorization information for the mobile unit 1, the cell controller 18 determines whether the call request of the mobile unit 1 must be queued for a later connection. If the profile and authorization information of the mobile unit 1 does not authorize queuing, the method follows the branch "no" to step 224 where the call request of the mobile unit 1 is terminated. The mobile unit 1 does not you can wait to queue your call request if, for example, mobile unit 1 is a low priority voice service. East P1094 / 00MX low priority voice caller expects to be excluded from the network from time to time, but this voice caller probably does not want to wait in a queue of indeterminate duration. Instead, this low priority voice caller can simply wait to place your call later. On the other hand, if the mobile unit 1 is a low priority data service, this data caller may wish to queue his call for further service. If the cell controller 18 determines in step 220 that the mobile unit 1 has registered with the service provider for queuing, the method then follows the branch "yes" to the step 208. In step 208, the call request from the mobile unit 1 is queued to wait for the next available channel in the cell 22. In step 208, the cell controller also notifies the mobile unit 1 that its call request has been placed on queue so that the mobile unit 1 does not continue to send new call requests to the mobile switch 14. In step 210, the queue is sorted by priority and timeout, so that the call request with the highest priority and the Longest wait time is at the head of the queue and will be assigned to the next available channel in cell 22. After sorting the queue in step 210, the method returns to step 202 to search for the next channel P1094 / 00MX available in cell 22 for the call request for the remote user at the head of the queue. However, if in step 206, the cell controller 18 determines that a channel in the cell 22 is being used by a remote user, such as the mobile unit 2, with a lower priority than the mobile unit 1, the method follows to the branch "yes" to step 212. In step 212, the cell controller 18 terminates the lower priority data call of the mobile unit 2, and in step 216, the cell controller 18 allocates the left channel empty to the mobile unit 1. The call of the mobile unit 1 is completed and terminated in step 222. The selection of the mobile unit 2 for the call termination in step 212 is based on the priority of the mobile unit 2 and in the duration of the call of the mobile unit 2 at the time of termination. For example, if several current remote users have the same priority as the mobile unit 2, which is a lower priority than that of the mobile unit 1, the cell controller 18 will terminate the call of the remote user who has been connected for the longest time. In this case, the mobile unit 2 is assumed to be the call with the longest duration of these users with the same priority as the mobile unit 2. As part of the termination process of the mobile unit 2, the computer program that controls P1094 / 00MX the data transmission to and from the mobile unit 2 will recognize the termination and mark the point in the transmission where the call termination occurred. At the resumption of the call to mobile unit 2, the computer program will be able to put the data transfer at the termination point. After the call of the mobile unit 2 has been terminated in step 212, the step proceeds to step 218, where, based on the profile and authorization information of the mobile unit 2, the cell controller 18 determines whether a request by the mobile unit 2 for the resumption of his call he must be put in the queue. If the profile and authorization information of the mobile unit 2 does not authorize queuing, the method follows the "no" branch from step 218 to step 224 where the call request of the mobile unit 2 to resume is terminated. Alternatively, the method follows the "yes" branch from step 218 to step 214 where the cell controller 18 places a request to resume the finished call of the mobile unit 2 in the queue. In step 214, the cell controller 18 also notifies the mobile unit 2 that its call has been queued so that the mobile unit 2 will not attempt to re-establish its call by new call requests to the mobile switch 14. The queue is commands in step 210 as described previously, and the call requests ordered in P1094 / 00MX queue wait for the next available channel in cell 22 as indicated by the return route to step 202. If the terminated call for mobile unit 2 is transferring data to mobile unit 2 at the time of termination , the cell controller 18 can maintain the connection to the telephone, switched, public network 12 for the resumption of the data transfer when the call to the mobile unit 2 is resumed in an unoccupied channel. Alternatively, the cell controller 18 can store all the caller data in the buffer 16, terminate the call from the telephone, switched, public network 12, and transfer the data from the buffer 16 to the mobile unit 2 in the re-acquisition of an unoccupied channel for the mobile unit 2. This storage and data transmission will be described in greater detail together with figure 3. On the other hand, if the terminated call of the mobile unit 2 is transferring data from the unit mobile 2 to a caller in the telephone, switched, public network 12, the cell controller 18 will maintain the connection to the telephone, switched, public network 12 until a channel for the mobile unit 2 is readied and the transmission is completed. Returning to Figures 3A and 3B, a flow chart showing the method of the P1094 / 00 X present invention when a caller from the public switched telephone network 12 requests service from the remote user 26 (mobile unit 1) within the cell 22. The method of the present invention begins at step 300 with a request for service for the telephone network 12, switched, public for a call in the mobile unit 1 in the cell 22. The request for the service in the mobile unit 1 is transmitted from the public switched telephone network 12 to the mobile switch 14. After after receiving the call request in step 300, the method proceeds to step 304. In step 304, the cell controller 18 asks the HLR database 20 to determine the service priority for the mobile unit 1 based on the profile and authorization information for the MIN of the mobile unit 1. Based on the priority of the mobile unit 1, the cell controller 18 determines in step 301 whether the call is a data transfer call. If in step 301, the cell controller 18 determines that the call is not a data transfer call, the method follows the "no" branch to step 302 (Figure 3B). If in step 301, the cell controller 18 determines that the call is a data transfer call, the method follows the "yes" branch to step 303. In step 303, P1094 / 00MX the cell controller 18 determines whether the data should be stored in the buffer 16. The decision to store or not store the data in step 303 is based on the estimation of the cell controller of the waiting time before that a connection is made to the mobile unit 1. If the data is not stored, the method follows the branch "no" to step 302 (Figure 3B) and retains the connection to the incoming caller on the telecommunications network 12, switched , public. If the data is stored in step 303, the method follows the "yes" branch to step 307. In step 307, the incoming data from the public switched telephone network 12 is stored in the buffer 16, and the connection ends from the telephone network, switched, public. The use of buffer 16 and step 307 is optional, and mobile switch 14 can simply maintain the connection to the public switched telephone network until data transmission to the mobile unit 1 is completed. data is stored in buffer 16 in step 307, the method proceeds to step 302 (Figure 3B). In step 302, the cell controller 18 of the mobile switch 14 finds out if there is an unoccupied channel available to service the call request to the mobile unit 1. If there is an unoccupied channel in the cell 22, the method follows the P1094 / 00MX branch "yes" to step 316, and the idle channel is assigned to mobile unit 1 without considering the priority of mobile unit 1. Once the call to mobile unit 1 is terminated, the method continues to step 322 where the call to the mobile unit 1 is terminated and the data for the mobile unit 1 is emptied (marked to be overwritten) from the buffer. If there is no unoccupied channel available, the method follows the "no" branch to step 306. In step 306, the method determines whether there is a current remote user in cell 22 that has a lower priority than the priority of the mobile unit 1. If all users have a priority equal to or greater than the priority of mobile unit 1, the method follows the "no" branch to step 320. In step 320, the cell controller determines the profile e authorization information of the mobile unit 1 and the handling of the incoming data if the call request to the mobile unit 1 should be queued. If the incoming data was not stored in step 307 (Figure 3A) then the request for call to mobile unit 1 can not be queued, and the method follows the "no" branch to step 324, where the incoming call request is terminated, and the incoming caller is notified that the connection was not made to the mobile unit 1. If the data The incoming ones were stored in step P1094 / OOMX 307 (Figure 3A), then the call request to the mobile unit 1 will be queued by the cell controller 18, and the method will follow the "yes" branch to step 308. In step 308, the call request to the mobile unit 1 is placed in the ordered queue, the mobile unit 1 is notified that it has an incoming call request, queued, which is waiting for the next available channel in the cell 22. In the step 310, the queue is sorted by priority and timeout so that the call request with the highest priority and the longest timeout is moved to the head of the queue for allocation to the next available channel in the cell 22. After sorting the queue in step 310, the method returns to step 302 to search for the next available channel in cell 22 for the call request at the head of the ordered queue. However, if in step 306, the cell controller 18 determines that a channel in the cell is being used by a remote user, such as the mobile unit 2, with a lower priority than the mobile priority 1, the method follows the branch "yes" to step 312. In step 312, the cell controller 18 terminates the lower priority data call of the mobile unit 2, and in step 316 allocates the left empty channel to the mobile unit 1. selection of mobile unit 2 for completion Call P1094 / 00MX is based on the priority of the mobile unit 2 and the duration of the call of the mobile unit 2 at the time of termination. As part of the termination process for the mobile unit 2, the computer program that controls the transmission of data to and from the mobile unit 2 will recognize the termination and mark the point in the transmission where the call termination occurred. In the resumption of call to mobile unit 2, the computer program will acquire the data transfer at the termination point. After the call of the mobile unit 2 has been terminated in step 312, the method proceeds to step 318, where the cell controller 18 determines whether the request of the mobile unit 2 to resume its connection should be queued or terminated . If the call request to resume is to be terminated, the method follows the "no" branch to step 324, where the cell controller 18 terminates the request of the mobile unit 2 to resume its terminated call. Alternatively, the method follows the "yes" branch from step 318 to step 314, where the cell controller 18 places the request of the mobile unit 2 to resume its terminated call on the ordered queue and notifies the mobile unit 2 that your request to resume has been queued. The queue is sorted in step 310, and call requests PX094 / 00MX in the queue wait for the next available channel in cell 22 for the call request at the head of the queue as indicated by the return route to step 302. Based on the above, it can also be seen that The present invention also contemplates multiple priorities for multiple levels of service. For example, voice callers could be given multiple levels to distinguish emergency services from other voice calls. In a transmission of data of a lower priority level they could be further subdivided, for example, to provide a higher priority for facsimile transmission than for the transmission of electronic mail. Additionally, the email could be further subdivided to provide higher and lower levels of priority service. Each priority could offer a separate rate. The ordering of the queue in the mobile switch 14 ensures that the various requests for service for each device are serviced in the order of the appropriate priority as the unoccupied channels become available.
