Description

METHOD AND ASSOCIATED APPARATUS TO SELECTLY TRANSMIT DATA IN PACKAGES A MOBILE TERMINAL The present invention relates in general to packet data transmission in a radio communication system such as a cellular communication system, which allows both packet data communication and short message service transmission.

(SMS = Short message service). More particularly, the present invention relates to an associated method and apparatus for selectively enabling data transmission in packets to a mobile terminal operable in the radiocommunication system. Charges are applied to the mobile terminal for each transmission made of packaged data. During operation of one embodiment of the present invention, packet data is transmitted to the mobile terminal only with the permission of the mobile terminal. The transmission of unwanted or otherwise unsolicited packet data is selectively avoided in the mobile terminal by denying permission to transmit packet data to it. The data in packets is transmitted to the mobile terminal, only if the mobile terminal allows transmission. An SMS message first transmits to the mobile terminal. The SMS message provides the mobile terminal with the identity of the originator of the data packet. A user of the mobile terminal, once it is provided with the identity of the originator of the data packet, chooses whether to accept the transmission of the packet. If a selection is made to not accept the transmission, the data packet is not sent. Only data transmissions in packets allowed by the mobile terminal to be transmitted are sent over an air radio interface to the mobile terminal. In this way, the user in a mobile terminal is able to control which data packets are transmitted to the mobile terminal. Costs associated with the transmission of data packets from the mobile terminal in this manner can also be controlled. BACKGROUND AND THE INVENTION Advances in communications technologies have allowed significant improvements in both performance and cost, in the communication of data between a sending and receiving station. Advances in the field of radio communications, for example, have allowed the introduction of and extensive use of both new and improved types of radio communications systems. For example, digital communication techniques have been implemented in various radiocommunication systems. These implementations have sometimes allowed multiple increments in the communication capabilities of these communication systems. Cellular communication systems are exemplary in radiocommunication systems where digital communication techniques have been widely implemented. When a digital communication technique is used, for example a single carrier can be used to form more than one channel. The communication capacity of a cellular communication system where a digital communication technique is implemented, typically allows in this way an increase of several times the communication capacity of the system. Advances in communications technologies have also facilitated the decentralization of carrier systems. Increasingly, computer systems are made up of decentralized processing devices, distributed in separate sites and connected by network connections. Intelligent peripheral networks (IP = Inteligent Peripherals) such as the Internet, are formed from these networked distributed processing devices. Sending and receiving stations, sometimes referred to as "guest devices" or "guests", transmit and receive data packets when a packet channel that forms a communication channel between them is available to communicate the packets. The packet channel is shared by many users and used to transmit a packet of particular data when the channel is available to do so. The communication of data packets between the distributed processing devices allows training communication between these distributed devices and in a cost efficient manner over a shared packet channel. The fusion of technologies has allowed the implementation of radio communication systems in which an IP host device is coupled by a radio link to allow in Internet communications or other data in packets with a guest device coupled to a conventional physical line network. For example, a terminal device such as a portable computer can be coupled via a radio link to a network infrastructure of a radio communication system and in turn via a network connection to a guest device connected to the Internet. The terminal device forms a wireless guest to the guest device connected to the Internet. A physical link, such as physical cabling, is not formed with the wireless guest device. In contrast, a packet channel is defined on the radio link to allow communication of data packets with the wireless guest device. Packet switched communications advantageously allow several mobile users to share an available channel capacity. In effecting communication by packet data transmission in a shared packet channel, it is therefore a less expensive way by which it is communicated than by resorting to a conventional circuit switched communication channel. In communications over a circuit switched communication channel, the channel is dedicated for communication between a pair of simple send / receive stations. Also, packet switched communications are particularly susceptible to communication of data that are of a "burst" nature transmittable in discrete bursts. Standards have been established and channels assigned for packet data communication in various cellular communication systems, such as the Generic Package Data Service (GPRS) in the general system for mobile communications (GSM = General Systems for Mobile Communications) and the PPDC (PDC in packets) in the personal digital cellular network (PDC = Personal Digital Cellular) in Japan. These cellular communications systems also allow short message service (SMS = Short Message Service) communications. The communications in SMS are made in control channels, also used for control signaling. SMS messages communicated to the mobile terminal are therefore the least expensive way in bandwidth by which messages are communicated to a mobile terminal. A mobile terminal that operates on these systems is operable according to a service subscription. Communications with the mobile terminal are charged to the subscription of the service. The charges are typically accumulated to the service subscription for each communication switched in circuit or switched in packets with the mobile terminal. That is, the subscriber, typically the user of the terminal to the service subscription must pay a fee each time the terminal m. { Ovil is used either to send or receive communications. These charges accrue for both circuit switched communications and packet switched communications. Because SMS messages are transmitted over a signaling channel, charges to communicate these messages are typically not detailed separately. Due to the unilateral nature of a packet data transmission, unsolicited data packets can be transmitted to the mobile terminal. Because a charge is applied for each communication from the mobile terminal, the service subscription may be charged by transmitting unsolicited or otherwise unwanted data packets to the mobile terminal.

One way by which the transmission of data packets to the mobile terminal is prevented or otherwise filtered without the user's permission of the mobile terminal, would be to avoid the application of charges for the transmission of unwanted packets to the mobile terminal . It is in light of this background information related to packet data communications systems that significant improvements of the present invention have evolved. SUMMARY OF THE INVENTION The present invention accordingly advantageously provides an associated method and apparatus for selectively enabling packet data transmissions to a mobile terminal operable in a radio communication system. The mobile terminal is provided with an indication of the light originator of another packet intended to conclude at the mobile terminal. Selection is made in the mobile terminal to allow the transmission of packet data to the mobile terminal in response to the indication of the originator of the packet data. A user of the mobile terminal in this way is able to control the transmission of packet data to the mobile terminal. Data in packets originating from unknown sources, probably indicative of an unwanted advertising content of packet data, can be prevented from being transmitted to the mobile terminal. Since charges accrue to the mobile terminal for each packet data transmission, the user of the mobile terminal is able to avoid charges that accrue from transmission by sending unsolicited data packets or otherwise. not wanted . In one aspect of the present invention, the radio communication system comprises a cellular communication system, such as a general system for mobile communications (GSM) or PDC communication system.

In these systems, the transmission of circuit switched data, packet data communications and also SMS messages are also available. When the packet data originating from a source concludes at the mobile terminal, the packet data is sent, such as by a backbone of the Internet, to the network infrastructure of a public network mobile network (PMN = Public Mobile Network) where the terminating mobile terminal is operable. The originator of the packet data is determined, such as by header information analysis of the packet data. An SMS message is formed that identifies the originator of the data packet that will end at the mobile terminal. The SMS message is transmitted to the mobile terminal in conventional manner, for example on a digital signaling channel. The SMS message is displayed on the mobile terminal, in this way to inform a user of the mobile terminal that a data packet originating from that source will terminate at the mobile terminal. The user of the mobile terminal is subsequently able to select whether to accept the transmission of a data packet. If selection is made not to accept the transmission, the data packet is not sent. If a selection is made not to accept the transmission, the data packet is not sent. Only if an affirmative selection is made and then it returns to the PLMN infrastructure, the transmission of the data packet is allowed, after the packet channel is established to the mobile terminal. In this way, the user of the mobile terminal is able to control the transmission of data packets to the mobile terminal. Costs associated with the transmission of the data packets to the mobile terminal, in this way they are capable of being controlled by the user of the mobile terminal. In this way, accumulated charges for receiving unwanted or otherwise unsolicited data packets are avoided. In another aspect of the present invention, packet data ending in the mobile terminal operating in a PLMN is received in a gateway mobile packet switching facility (GPMSC = Gateway Package Data Mobile Switching Center). The GPMSC is operable, among other things to translate a terminating IP address forming a portion of header information of the data packet to a mobile serial number identifying a mobile terminal that is operated in the PLMN. If a mobile serial number (MSN = Mobile Serial Number) is indexed against the IP address, the GPMSC is additionally operable to search for the location registered in the mobile terminal identified by the MSN. In another aspect of the present invention, the mobile terminal is operable to receive an SMS message indicating the identity of an originating source that originates packet data to be terminated in the mobile terminal. The mobile terminal includes a display element for the identity of the source of origin and an actuator, which is operated by a user of the mobile terminal to generate a return signal back to the infrastructure of the PLMN. The return signal grants permission to transmit the packet data to the mobile terminal. Control over packet data transmission to the mobile terminal is thus provided to a user in the mobile terminal. The transmission of unwanted or otherwise unwanted data packets to the mobile terminal is avoided.

In these and other aspects, therefore, a method and associated apparatus selectively allow packet data transmission to a mobile receiving station of a radio communication system. The mobile reception station is coupled by a radio interface to a network infrastructure of the radio communications system. A sending station is coupled to the network infrastructure, and the radio interface includes a short message channel and a packet channel. Data in packets originating from the sending station are detected in the network infrastructure. An identity of the sending station from which the packet data originates is determined in the network infrastructure. An indication of the identity of the sending station is sent, via the short message channel, to the mobile receiving station. The mobile receiving station detects the indication of the identity of the sending station that is sent by the short message channel. The selection is made at the mobile reception station, either to affect the transmission of packet messages originating from the sending station in response to the indication of the identity of the sending station detected at the mobile receiving station. If selection is made to accept the transmission of the packet data at the mobile reception station, the packet data is sent, via the packet channel to the mobile receiving station. A more complete appreciation of the present invention and the scope thereof may be attained from the accompanying drawings which are briefly described below, the following detailed description of the presently preferred embodiments of the invention and the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 illustrates a communications system wherein one embodiment of the present invention is operable. Figure 2 illustrates a sequence diagram that lists trajectories of signals generated during operation of a modality of the present invention. Figure 3 illustrates a functional block diagram of a wireless station forming a portion of the communication system found in Figure 1. Figure 4 illustrates a method flow diagram that lists the method operation of an embodiment of the present invention. . DETAILED DESCRIPTION Again with reference to Figure 1, a communication system, generally shown at 10, allows the communication of packet data generated by an Internet guest 12 to communicate to a mobile terminal 14. The mobile terminal is coupled by a radio link, here identified by line 16, shown in dotted lines, extending between terminal 14 and a public land mobile network (PLMN = Public Land Mobile Network) 18. PLMN 18, in turn is coupled by an axis Internet trunk 22 to which the Internet host 12 is coupled. In the illustrated embodiment, the mobile terminal 14 includes a wireless guest 24 and a radio transceiver 26. The wireless guest 24 is coupled to the radio transceiver 26, for example by a Infrared connection or physical wiring. The radio transceiver is constructed to be operable in accordance with an air radio interface standard, such as RCR 27-STD (air interface standard) PDC system), EIA Standard / TIA IS-54 or IS-136. In other embodiments, the wireless guest 24 and the radio transceiver 26 form a single unit. The PLMN 18 is constructed in a corresponding manner to meet the operational requirements of a selected air interface standard, such as one of the aforementioned radio air interface standards. The PLMN 18 illustrated here includes a base radio station 32. The base station 32 includes transceiver circuits that allow transmission and reception of communication signals with the radio transceiver 26 of the wireless station 14. The base station 32 and the radio transceiver 26 both are capable of communicating both circuit switched data and packet switched data. The base station is coupled to a mobile switching center (MSC = Mobile Switching Center) 34, here a visited mobile switching center (VMSC = Visited Mobile Switching Center). The VNSC 34 is shown here coupled in turn to another MSC here a mobile gate switching center (GMSC) 36. A home location register (HLR = Home Location Register) is additionally coupled to the VMSC 34. While the HLR 42 shown functionally separate from the VNSC 34, the HLR 42 can physically be co-located with the VMSC 34. Analogously, the base station 32 is also coupled to a mobile packet switching center (PMSC = Package Mobile Switching Center), here a mobile switching center in visited location packets (VPMSC = Visited-Location Packet Mobile Switching Center) 44. The VPMSC 44 in turn is coupled to another PMSC, here a gateway mobile packet switching center (GMPSC) 46. The PMSC 44 is also coupled to the HLR 42.

While not shown separately, the HLR 42 also connects to other network nodes, ie other MSCs and PMSCs such as GMSC 36 and GPMC 46. Information stored in the HLR, therefore, is similarly accessible by these other network nodes. The GPMSC 46 in turn is coupled to a NIM 52 that also couples to a backbone of the Internet 52. The packet data generated by the Internet guest is routed through the backbone of the Internet 22 that supply the GPMSC 46. The PLMN also includes a Short Message Service Center (SMC-C = Short Message Service Center) 56.

The SMS-C is operable to generate SMS messages. The SMS-C 56 is functionally coupled to both the VPMSC 42 and the GMSC 36. During operation of one embodiment of the present invention, packet data originating in the Internet host 12 upon completion at the wireless station 14, are transmitted over the air radio interface to be terminated. in the wireless station 14 only with permission of the wireless station. Packets of unsolicited or otherwise unwanted data may be refused permission by the wireless station 14 to be transmitted by the PLNM 18 to the wireless station. An SMSC message identifying the source of origin is the identity of the internet host 12, at least it is generated by the SMS-C 56 and it is transmitted over a control channel, in a conventional manner, to the wireless station 14. In response to reception in the wireless station of the SMS message, a determination is made as to whether the data is allowed to be transmitted in packet. If permission is granted to the PLMN 18 to transmit the packet data to the mobile terminal, the mobile terminal registers to receive packet data. The communication system 10 is exemplary of a Personal Digital Cellular Communication (PDC = Personal Digital Cellular) system that provides PDC data communication in packets (PPDC = Packet PDC) over a radio link to a wireless station, here the wireless station 14 Mobility control for packet communications for example between the Internet host 12 and the mobile terminal is performed at a radio interface layer using the mobile serial number (MSN) of the radio transceiver 26 of the mobile terminal 14. Mobility management functions, such as location registration and channel transfer, are carried out in a manner similar to the ways in which corresponding functions are carried out in circuit switched communications.

The packet data originated by the Internet host 12, are headed by the header information, which identifies the wireless guest 24 to which the packet data will be directed. Conventionally, the data packet originated by the Internet host 12 is routed over a backbone of the Internet 22 to the GPMSC 46. The GPMSC 46 translates the destination IPD address identified in the header information of the packet data to an associated MSN with the radio transceiver 26 to which the wireless guest 24 is coupled. If there is an MSN corresponding to the IP address, the GPMSC 46 then searches for the location of radio transceiver 46 in a local HLR cache. If it is not there, interrogation is made to the HLR 42 of the location, for example the base station or associated cell, where the radio transceiver 42 is registered to be located. In the exemplary illustration, the mobile terminal is registered to be located in an area served by VPMSC 44. The service VPMSC 44 is identified for example by a VPMSC area identifier (PAI). Also, conventionally, the packet data is encapsulated, for example in a PMAP protocol, and sent from the GPMSC 46 to the service VPMSC 44, which serves the addressed mobile terminal 36. The service VPMSC de-encapsulates the packet data and sends the data. packet data de-encapsulated to the radio transceiver 26 by the base station 32 on the radio link 16. If the radio transceiver 26 is in a packet state, the packet is transmitted on a user packet channel (PCH = User Packet Channel) which is registered for the radio transceiver 26. If, on the other hand, the transceiver radio 26 is in an idle state, a packet radiolocation message it is sent to the VPMSC 34 serving the radio transceiver 26. And, the radio transceiver 26 is caused to radio locate on a channel. If the radio transceiver 26 is radio localized, the radio location message transmitted over a location radio channel (PCH = Paging Channel) subsequent to receiving the radiolocation message, the radio transceiver 26 performs a packet communication log with the VPMSC 44 in a available UPCH. Once the radio transceiver is successfully registered, the radio transceiver enters a state of packets and the packet data is sent from the VPMSC 44 to the base station 32 and over the radio link 16 on the same UPCH used by the radio transceiver 26 for registration purposes. When the radio transceiver 26 transmits data to be terminated in the Internet host 12, the VPMSC 44 receives the data. The data is encapsulated and sent to an appropriate GPMSC, here the GPMSC 46. The GPMSC 46 de-encapsulates the received packet data and sends the packet data to the external network here, the backbone of the Internet 22. An embodiment of the present invention it allows selection to be made at the wireless station 14 as to whether or not packet data transmission is allowed. If for example the mobile terminal 26 is in an idle state, a decision can be made not to enter a packet state and not allow the transmission of the packet data. Figure 2 illustrates a sequence diagram generally shown at 82, illustrating sequences of signal generation during operation of the embodiment of the present invention. Data in packets generated by the Internet host 12 forming a portion of the communication system shown here in Figure 1 are selectively directed to the mobile terminal 14 of the communication system. First, and as indicated by the sequence segment 86, the packet data originating in the Internet host 12 is routed via the Internet backbone 22 and received in the GPMSC 46. The packet data includes head information indicating the IP address associated with the wireless guest 24 of the terminal 14. The GPMSC translates the IP address associated with the wireless guest 24 into an MSN associated with the radio transceiver 26. The location of the mobile terminal is then determined, first by interrogating a cache of local HLR. If the location of the radio transceiver 26 can not be determined by polling the local HLR cache, the HLR 42 is interrogated to determine the location of the radio transceiver as indicated by the sequence segment 88. The location of the register, stored in the HLR, is provided to the GPMSC as indicated by the sequence segment 92. The packet data is encapsulated, for example in a PMAP protocol by the GPMSC 46. And the encapsulated data is sent indicated by the sequence segment 94 by the GPMSC 46 to the VPMSC 44. The VPMSC 44 is the PMSC that serves the mobile terminal addressed. The encapsulated data, which is received by the VPMSC 44 are decapsulated, indicated by the activity block 98. The IP address of the wireless guest 24 contained in the head formation of the packet data is investigated. The PMSC, for example, performs a domain name search (DNSC = Domain Name Search) to search, for example, the source IP address, to obtain a guest number and validate the type of service, for example FTP, Telnet, etc., for which the packet data transmission is intended. In response to the investigation, the packet data including the source IP address, the guest number and the type of service, are sent as indicated by the sequence segment 102 to the SMS-C 56. The information is sent using a type conventional communication method, for example X.25 communications. The SMS-C 56 in turn issues an SMS message indicated by the sequence segment 104 to the GMSC 36 in forms corresponding to conventional short message procedures. The GMSC 36, in turn interrogates, indicated by the sequence segment 106, the HLR 42 of the location of the radio transceiver 26. And this information is provided, indicated by the sequence segment 108, to the GMSC 36. The SMS message subsequently is directed, indicated by the sequence segments 102 and 114 by the GMSC 36 by the VMSC 34 over the radio link 16 to the mobile terminal 14. Once the radio transceiver 26 of the mobile terminal 14 receives the SMS message that is sends it, an acknowledgment of reception of the SMS message indicated by the sequence segments 106, 118 and 122 is returned to the SMS-C 56 via the VMSC 34 and the GMSC 36. A determination is also made by the external block 124 of the terminal mobile 14 if packet data transmission is allowed originated by the Internet guest 12, as identified in the SMS message, to the mobile terminal. When a determination is made to allow the transmission of the packet data, an indication of this permission is provided by the mobile terminal, indicated by the sequence segment 128, wherein the radio, transceiver initiates registration to enter the packet state, according to package communication registration procedures. Subsequently, the packet data is directed to the mobile terminal 14. Figure 3 illustrates portions of the mobile terminal 14, which were previously shown in Figure 1, operable in the communication system 10. The mobile terminal 14 includes reception circuits 142 for receiving, among others, SMS messages broadcast to the mobile terminal 14. The receiver circuits 142 are representative of portions of the circuits of the radio transceiver 26 shown in Figure 1. The mobile terminal 14 further includes an exhibit element 144. and a selector 146. Both the display element and the selector 146 are coupled to the circuits of the receiver 142. The display element 144 and the selector 146 in one embodiment are formed of portions of the radio transceiver 26 and are for example formed of display elements of the mobile terminal and its operating keypad, respectively. In another embodiment, the display element 144 and the selector 146 form portions of the wireless guest 24, for example the monitor for video display and operating push-button, respectively of the wireless guest. When the SMS message indicating the originator of the packet data is received in the receiver circuits 142, this identification is presented in the display element 144. A user of the mobile terminal determines, in response to the displayed information, whether the it allows transmission of the packet data to the mobile terminal 14. The selection of the permission to receive the packet data is supplied by the selector 146. When permission is granted to transmit the packet data to the mobile terminal 14, the mobile terminal 14 register to receive data in pack. Subsequently, the packet data is directed to the mobile terminal. Figure 4 illustrates a method generally shown at 162 of one embodiment of the present invention. The method selectively allows the transmission of packet data to a mobile reception station. The mobile reception station is coupled by a radio interface to the network infrastructure. And a sending station that originates the packet data is coupled to the network infrastructure. First and as indicated by block 164, the packet data originated by the sending station is detected in the network infrastructure. Then and as indicated by block 166, the identity of the sending station from which the packet data originates is determined. An SMS message is formed, which indicates the identity of the sending station. The SMS message is sent as indicated by block 168 to the mobile receiving station. The SMS message is detected at the mobile receiving station, as indicated by block 172. Selection is then made, as indicated by block 174, if the transmission of packet data originating from the second station is accepted. And the packet data is sent to the mobile receiving station, indicated by block 176 if the transmission at the mobile receiving station is accepted. In this way, the packet data is transmitted to the mobile terminal only with permission of the mobile terminal. The transmission of unwanted or otherwise unwanted packet data is thus avoided in a selectable manner in the mobile terminal, by denying permission to transmit the data in a packet. The user of the mobile terminal is able to control, in this way, which data packets are transmitted to the mobile terminal. Also, in this way the costs associated with the transmission of the data packets to the mobile terminal can be controlled.

The foregoing descriptions are of preferred examples for implementing the invention and the scope of the invention will not necessarily be limited by this description. The scope of the present invention is defined by the following claims.
