Abstract

PROBLEM TO BE SOLVED: To allow a PPP server to automatically access a network resource to which the PPP server connects when the PHS data communication terminal enters a zone of a CS. SOLUTION: When the PHS data communication terminal enters a zone of a cell station CS connecting to a PPP server, the CS assigns a link channel to the terminal. In this case, the CS makes a PS-ID authentication request 30 to the PPP server by using a PS-ID of the PS(personal station) terminal entering the zone. Then the PPP server authenticates whether or not the indicated PS-ID is in matching with a registered IS and returns a PS-ID authentication reply 31 to the CS when the indicated PS-ID is in matching with the registered PS-ID. Then the CS makes a PPP start request 32 to the PS and the PS adopts the sequence control method to make a call and to start PPP connection accordingly.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a PHS data communication terminal device and a sequence control method therefor.

[0002]

2. Description of the Related Art Conventionally, in communication of a PHS terminal, a control sequence has been standardized by RCR STD-28. The control sequence in PPP is RF
C (Request For Comment) -1661 (PPP in general,
Especially LCP (Link Control Protocol) phase), R
FC-1334 (PPP authentication phase), RFC-13
31 (implementation for IP (Internet Protocol) in the PPP-NCP (Netwoke Control Protocol) phase).

Hereinafter, the configuration will be described with reference to the drawings. In addition, RT (Radio frequency Transmisson
Manager) indicates radio management, MM (Mobility Management) indicates mobility management, and CC (Cell Control) indicates call control.

FIG. 2 shows a conventional transmission control sequence and PPP sequence. First, RSR-ST
The D28 link channel establishment phase will be described.

A PS (Personal Station) is a CS (Cell)
Station 1) sends a “link channel establishment request 1”. This message includes a destination identification code (PS-I
D), caller identification code (CS-ID), message type, L
CH type, LCH protocol type, extended LCH protocol type, CC protocol type, system type, RT / M
M protocol version and area information notification number are included. Thus, the PS specifies the type of link channel required for communication and the type of protocol required for call connection. At this point, the PS-ID of the PS has been notified to the CS.

The CS allocates a link channel to the PS and sends out “link channel establishment allocation 2”. PS
Is used by the CS to allocate a channel in response to a request for a link channel. Information such as a carrier number and a relative slot number is included. Prior to transmission of this message, the CS checks whether the type of the link channel and the type of the protocol can be provided from the PS.

Next, the RCR-STD28 service channel establishment phase will be described. The PS sends out “synchronous burst 3” to the CS. In response, the CS sends a “sync burst 4” to the PS.

Next, the PS sends “SABM (asynchronous balanced mode setting) 5” to the CS. The CS sends “UA (Unnumbered Acknowledge) (SABM) to the PS.
(Acknowledgment response to SetAsynchronous Balanced Mode) 6) is transmitted. Call setup is started by sending "CC call setup 7" to CS. Set "CC call setting" to C
When S receives and confirms that the admission is valid, CS returns "C" to indicate that it is handling the call.
"C call setting reception 8" is sent to the PS, and the state transits to the call reception state.

When the PS has received the notification information receiving instruction, the PS requests the notification information by "RT definition information request 9". The CS receiving the message "RT definition information response 1"
The notification information is notified by “0”.

A PS instructed to make an RT function request
Requests the CS to the RT function by the "RT function request 11". The RT function specified by the PS is notified to the PS by “RT function request response 12”.

The PS transmits the secret key to the CS using the “RT secret key setting 13”. The PS instructed to make the MM function request requests the MM function to the CS by “MM function request 14”. The received MM function is notified to the PS by "MM function request response 15".

When the necessary function request from the PS is completed, C
S generates an authentication random number and sends "MM authentication request 16" to the PS to notify the PS of the random number. The PS that has received the “MM authentication request” notifies the CS of an authentication calculation result using the authentication key having a random number.

The CS receiving the “MM authentication response 17”
Similarly, it is determined whether or not the calculation result obtained using the authentication random number and the authentication key in the home memory of the PS is the same as that notified by the PS. If the authentication result is valid, the call connection is continued. The CS receives an indication that the call has started and sends a "CC Call 18" to the PS. CS
Confirms that the call has been accepted,
9 "to the PS.

[0014] When the PS indicates that the call cannot be accepted from the CS, the PS initiates a call release procedure in accordance with the rules for call disconnection recovery.

By the above procedure, the PHS terminal enters a communication phase (a state in which data communication is possible).

[0016] Hereinafter, a procedure performed between the terminal and the PPP server after data communication becomes possible by the PHS will be described.

In order to establish point-to-point PPP communication, it is necessary to first send an LCP setting request and a test packet in the PPP-LCP phase. After the packets have been transmitted, they move to the PPP authentication phase where the terminal is authenticated, and then in the PPP-NCP phase, the PPP-NCP
Request one or more network protocols in a packet. Once each of the chosen network layer protocols has been configured, datagrams from each network layer protocol can be sent on that link.

In the PPP-LCP phase, processing is performed in the following procedure. The PS sends “C” to the server side using parameters such as capabilities to establish a PPP link.
onfigure-Request 20 ".
The server sends PS “Configure-Ac”
k21 ".

In the PPP-authentication phase, processing is performed in the following procedure. The PS requests “Authenticate-Requests” to request authentication from the server.
t22 ". When the server confirms the password, it returns "Authenticate-Ack23".

In the PPP-NCP phase, processing is performed in the following procedure. In the PPP-NCP phase, individual processing is performed for the protocol specified by the configuration in LCP. In the following, a description will be given of the case of connecting by IP. The PS requests the server for an IP address as the PS's PPP client “IP
−Address 24 ”. At this time, PS is IP
You specify whether to specify an address or receive an assignment from the server. The server returns an IP address “IP-Address 25” that can be assigned to the PS.
This sequence fails if the IP address cannot be assigned. Next, the PS issues an IP packet compression request “IP-Compression 26” to the server. The server makes a response “IP-Compression 27” to the compression request of the IP packet.

Finally, a request "IP-Address 28" is sent from the PS for information such as a default gateway necessary for accessing the network beyond the server. Server is IP such as default gateway
Address to IP “IP-Address 29”
To send.

After these series of procedures are performed, connection procedures for higher-level protocols (TCP, UDP, etc.) are performed, and datagram transmission becomes possible.

[0023]

In the above conventional method,
The control phases of PHS and PPP are completely independent;
PS-I by the PPP server at the time of entering the HS area
It is impossible to perform authentication using D, make a PPP start request from the CS to the PS, and automatically start a PHS transmission sequence and a PPP connection sequence from the PS. It was not possible to automatically access the network resources to which the PPP server was connected.

The present invention has been made to solve the above-mentioned problem. The control sequence of PHS and PPP is organically combined, and when the PS comes within the range of the CS connected to the PPP server, the CS and the server perform PS control. An object of the present invention is to provide a method of performing authentication using an ID, automatically transmitting a call to a PS by a CS, and further performing a PPP connection.

[0025]

According to the present invention, when a PHS data communication terminal enters the area of a CS connected to a PPP server, a link channel is allocated by the CS. At this time, the CS issues a PS-ID authentication request to the PPP server using the PS-ID of the PS that has entered the service area. The PPP server indicates the PS indicated by the
-Authenticate whether the ID is registered, and if it is a registered PS-ID, return a PS-ID authentication response to CS. After that, CS makes a PPP activation request to PS,
The PS is a sequence control method that initiates a call and a PPP connection accordingly.

According to the present invention, it becomes possible to automatically access a network resource to which a PPP server is connected when a PS enters a service area of a CS, thereby making its use convenient.

[0027]
