Abstract
Abstract A method for starting a short message transmission in a cellular communication system, a cellular communication system, and a cellular communication system subscriber location register includes the subscriber location register which stores information on the fact that at least one short message service center stores short messages to be transmitted to a subscriber to whom the messages cannot be transmitted for the time being, and the subscriber location register of the subscriber which transmits to at least one short message service center a short message transmission starting message when it is again possible to transmit short messages to the subscriber. In order that short messages can be transmitted to subscribers selectively, the subscriber location register maintains short message service center and subscriber-specific information on the conditions under on which the short message service center is to be transmitted short message transmission starting messages.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
126 words
A method for starting a short message transmission in a cellular communication network, comprising: storing information in a subscriber location register based on the fact that at least one short message service center stores short messages to be transmitted to a subscriber to whom said short messages cannot be transmitted for the time being; transmitting from said subscriber location register of said subscriber to said at least one short message service center, a short message transmission starting message when it is possible again to transmit short messages to said subscriber, wherein information on conditions under which said short message service center is transmitted short message transmission starting messages is maintained specific to said short message service center and to said subscriber in said subscriber location register.
Claim 2
Independent Claim
126 words
A method for starting a short message transmission in a cellular communication network, comprising: storing information in a subscriber location register based on the fact that at least one short message service center stores short messages to be transmitted to a subscriber to whom said short messages cannot be transmitted for the time being; transmitting from said subscriber location register of said subscriber to said at least one short message service center, a short message transmission starting message when it is possible again to transmit short messages to said subscriber, wherein information on conditions under which said short message service center is transmitted short message transmission starting messages is maintained specific to said short message service center and to said subscriber in said subscriber location register.
Claim 3
Dependent Claim
90 words
The method according to claim 1, wherein said subscriber location register transmits said short message transmission starting messages concerning one subscriber to desired short message service centers, selectively, based on said maintained information so that starting messages are transmitted to only first short message service centers, which are desired to transmit short messages, and starting messages are not transmitted to second short message service centers, which are not desired to transmit short messages, even if said second short message service centers contain short messages to be transmitted to said subscriber.
Claim 4
Dependent Claim
44 words
The method according to claim 1, wherein said subscriber controls said conditions included in said information maintained in said subscriber location register so that said subscriber location register transmits short message transmission starting messages to said short message service centers desired by said subscriber.
Claim 5
Dependent Claim
27 words
The method according to claim 3, wherein in response to a control instruction transmitted by said subscriber, said subscriber location register does not transmit said starting messages.
Claim 6
Dependent Claim
44 words
The method according to claim 1, wherein an operator controls said conditions included in said information maintained in said subscriber location register so that said subscriber location register transmits short message transmission starting messages to said short message service centers desired by said operator.
Claim 7
Dependent Claim
30 words
The method according to claim 1, wherein said subscriber location register does not transmit said starting messages, if said subscriber is situated in a location other than a desired area.
Claim 8
Dependent Claim
36 words
The method according to claim 1, wherein said subscriber location register transmits short message transmission starting messages to desired short message service centers in an order prioritized according to addresses of said short message service centers.
Claim 9
Dependent Claim
