Portable terminal MS downloads coupon data and public key KEYPof IP serverfrom IP server. Service terminal T obtains from IP server, a server certificate to which a digital signature is applied by secret key KEYS. One to one local communication by infrared radiation is performed between portable terminal MS and service terminal T. At this point, portable terminal MS decrypts a server certificate by utilizing public key KEYPof IP server. Then, portable terminal MS communicates specified data after authenticating the identity of service terminal T.

Terminal communication system

The communication apparatus and browser switching method are capable of carrying out automatically an input of URL. A mobile device communicates with a server arranged in a network and has a first browser that processes and displays Web data acquired from the server, and a second browser that can process Web data that can not be processed by the first browser. In this mobile device, when a switching instruction is received from an operation part, a URL being a communication destination communicated with the first browser for communication is stored in a URL storage part. An application management part controls the second browser such that the second browser performs communication connection to the URL based on the stored URL.

Communication apparatus and browser switching method

A communication apparatus and display method are capable of displaying one frame of a plurality of frames, and displaying automatically an appropriate frame for a user in the case that there are changes in display contents. A display part displays screen data while enlarging a frame which is specified by the user and is included in Web data including a plurality of frames received by a data communicating part. While the screen data of the frame specified by the user is displayed, a frame configuration management part judges that changes took place in display contents of other frames that are not displayed. A data processing part performs data processing so as to cause all frames included in the received Web data to be displayed on the display part when it is judged that the changes took place in the display contents.

Communication apparatus and display method

Included are Gateway server GWS which clocks the precise present time, and portable phone MS which performs a packet communication through gateway server GWS and IP server W. Portable phone MS acquires the time information from gateway server GWS, at the time of starting communication with IP server W and corrects, on the basis of this time information, the clocking present time of its own portable phone MS so that it is more precise. In addition, portable phone MS decodes a public key certificate (an electronic certificate issued by Certificate Office C for the public key certificate of IP server W) using the public key of Certificate Office C. Then the portable phone MS judges whether it is within the validity period specified in the public key certificate, using the corrected present time of its own portable phone MS.

When downloading a Java&#x2122; application AP from a servera scheme and a transmission port number used by serverwhen downloading Java&#x2122; application AP are stored in addition to a host name of serverThen, when the Java&#x2122; application AP accesses a resource on the Internet, the host name of a resource to be accessed, and a scheme and a destination port number are compared with the stored host name, scheme, and transmission port number. The network access is permitted only when the compared items agree with each other.

Method and device for managing access to network

To enable a user of a communication terminal to note that the terminal has received data by data communication conducted in the background of a voice communication, easily and in the required time. After establishing a voice communication line between mobile phone-mobile phone-establishes a data communication line with mobile phone-and acquires image data. When disconnecting a voice communication line, mobile phone-produces a notification sound and displays the acquired image data, thereby notifying a user of mobile phone-of acquiring data by data communication during voice communication.

The present invention relates to a spreading signal assigning method and a signal transmitting method in a direct sequence CDMA mobile communication system, a mobile wireless communication system using the methods, and a transmitter, a receiver and a transceiver in the mobile wireless communication system in which an assignment method of a second spreading code is devised such that various services can be provided. The invention is configured such that a signal spread with the second spreading code is transmitted between a base station and a mobile station by assigning a code associated with each base station group or a code associated with each network type to which the base station group belongs as the second spreading code.

An application title, storage location information, and a download flag F is stored in an application control table TBL provided in table areaof EEPROMof mobile phone MS. The download flag F indicates whether the application is a downloaded application. When downloading an application from IP server W, CPUchanges the download flag corresponding to the application to '1'. When executing the application, CPUreads out the download flag F corresponding to the application and displays a predetermined image on a liquid crystal display MSwhen the download flag F has a value of '1'.

Terminal and repeater

If an e-mail is sent to a user of a communication terminal while the communication terminal is being used for voice communication, informing the user that the e-mail has been sent is controlled. Mobile phonestores an importance level in association with a telephone number and e-mail address. If a mail alert is received while mobile phoneis used for voice communication, an importance level of the voice communication partner and an importance level of the sender of the e-mail are read from a nonvolatile memory. The read importance levels are compared by mobile phone, and if the importance level of the sender of the e-mail is higher, mobile phoneinforms the user thereof that it has received the mail alert.

Communication terminal and program

At a terminal where communication can take place via a network, ADF in which property information on data is stored is received, and based upon the communication systems (ordinary/SSL) which were used for receiving this ADF and the communication system which is used for receiving JAR in which the entity of the above mentioned data is stored, whether a communication pattern is allowable determined. JAR is received if the communication pattern is allowable, and JAR is not received if the communication pattern is not allowable for security reasons. In other words, data is obtained only when the communication pattern is allowable.

Data obtaining method and terminals

IP server W and gateway server GWS transmit data in HTML format in response to a request from mobile unit MS. At this stage, in the HTML data, the personal identification information request data string is added to a URL of the page corresponding to a service, which requires user authentication. As the HTML data is received by mobile unit MS, the user carries out an inputting operation to designate the URL while the image corresponding to the HTML is displayed on the liquid crystal display unit. Then, mobile unit MS reads out personal identification information from ROM, and transmits to mobile packet communication network MPN. IP server W carries out user authentication on the basis of personal identification information transmitted from mobile unit MS in this manner.
