ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a mobile communication system that has a function to allow the user to browse text information, image information, and multimedia information. More particularly, the present invention relates to a mobile communication system and a program transmission method that allow a program and data, which is not stored in a system-relevant mobile station, to be downloaded from a base-station server to the mobile station according to need, thereby providing the mobile station with a new processing function.
BACKGROUND OF THE INVENTION
An example of a conventional mobile communication system is disclosed in Japanese Patent Application Laid-Open No. 11-75257. This system is provided with two means. One is means for, in response to a request issued from a mobile station (cellular phone), downloading a program and data from a server equipped in a base station to the mobile station. The other is means for making the program downloaded available in the mobile station. The conventional mobile communication system thus composed operates as follows. Namely, the user who is using the mobile station gives an operation to download the program and data according to need. According to this user's operation, the program and data is downloaded from the base-station server to the mobile station. Thereby, an additional service becomes available in the mobile station.
The problem of the above-described conventional mobile communication system is that the user of the mobile station has to give the operation to download the program and data to the mobile station. One reason of the problem is that there is no notification means for notifying, mutually between the mobile station and the base-station server having the program and data, whether the mobile station has a processing function needed to perform the addition service or not. The other is that, in the mobile station or the base-station server, there is no determination means for determining whether the mobile station has the necessary processing function or not.
SUMMARY OF THE INVENTION
An object of the invention is to provide a mobile communication system and a program transmission method that allow a program and data needed to perform additional services in a mobile station to be downloaded automatically and surely to the mobile station without the user's operation.
The invention will hereafter be explained using
FIGS. 1 and 2
. First, according to a first aspect of the present invention, in
FIG. 1
, there is provided a mobile communication system, including a mobile station
1
and a server
2
performing a communication with the mobile station
1
through a base station, wherein the mobile station
1
has provided therein notification means
11
that notifies mobile station's processing ability to the server
2
beforehand; reception means
12
that receives a program and data from the server
2
; program and data hold means
13
holds the program and data received from reception means
12
: execution means
14
executes built-in program and program held in hold means
13
, if needed execution means
14
accesses data held in hold means
13
; and processing means
15
that processes service information the mobile station receives from the server
2
using the program and data the mobile station receives from the server
2
, while the server
2
has provided therein storage means (mobile-station side processing ability hold means)
22
that stores therein the data processing ability that has been notified from the mobile station
1
; determination means (mobile-station side processing ability confirmation means)
23
that receives a request for the service information made from the mobile station
1
and that, according to the information stored in the storage means
22
, determines whether the mobile station
1
can process the service information; and transmission means
26
that, in the case the result of the determination made by the determination means
23
is NO (negative), transmits the service information to the mobile station
1
; and transmission means (download means)
24
that transmits the program and data for processing the service information.
Also, according to a second aspect of the present invention, in
FIG. 2
, there is provided a mobile communication system, including a mobile station
3
and a server
4
performing a communication with the mobile station
3
through a base station, wherein the mobile station
3
has provided therein reception means (service information receive means)
37
that receives service information from the server
4
, reception means
33
that receives the program and data for processing the service information from the server
4
; processing ability confirmation means
32
that determines whether the mobile station
3
can process the service information received from the server
4
using the information held in processing ability information hold means
31
and that, in the case the result of the determination is NO (negative), requests the server
4
to transmit the program and data for processing the service information, and processing means
36
that processes the service information using the program and data the mobile station
3
has received from the server
4
, while the server
4
has provided therein first transmission means
44
that, upon receipt of the request from the mobile station
3
, transmits the service information; and second transmission means (download means)
42
that, upon receipt of the request from the mobile station
3
, transmits the program and data.
According to a third aspect of the present invention, in
FIG. 1
, there is provided a program transmission method performing a program transmission between a mobile station
1
and a server
2
performing communication with the mobile station
1
via a base station, comprising a step (executed by processing ability notification means
11
) that the mobile station
1
notifies the data processing ability to the server
2
beforehand; a step (executed by service information receive means
16
) that when in the mobile station
1
a request for service information has occurred therefrom, the mobile station
1
transmits a request for the server
2
to transmit the service information; a step (executed by mobile-station side processing ability confirmation means
23
) that the server
2
receives this request and, according to the data processing ability of the mobile station
1
the server
2
is notified of beforehand, determines whether the mobile station
1
can process the service information; and a step (executed by download means
24
) that, in the case the result of the determination is NO (negative), the server
2
transmits the program and data for processing the service information along with this service information.
According to a fourth aspect of the present invention, in
FIG. 1
, there is provided a program transmission method performing a program transmission between a mobile station
1
and a server
2
performing communication with the mobile station
1
via a base station, comprising a step (executed by processing ability notification means
11
) that the mobile station
1
notifies the data processing ability to the server
2
beforehand; a step (executed by service information receive means
16
) that when in the mobile station
1
a request for service information has occurred therefrom, the mobile station transmits a request for the server
2
to transmit the service information; a step (executed by service information transmission means
26
) that the server
2
receives this request; a step (executed by mobile-station side processing ability confirmation means
23
) that, according to the data processing ability of the mobile station the server
2
is notified or beforehand, the server
2
determines whether the mobile station
1
can process the service information; a step (executed by download means
24
) that, in the case the result of the determination is NO (negative), the server
2
