First Claim
Patent Images
1. A method for restricting a push-to (PT) service comprising:
- setting network information for restricting session establishment;
determining whether a network of inviting PT client or invited PT client satisfies the network information; and
stopping session establishment between the PT clients if the network of at least one of the inviting PT client and the invited PT client satisfies the network information.

Abstract
A method for restricting a push-to (PT) service restricts a PT service with reference to network information. A PT client inviting to a PT session restricts an invited PT client by setting a network dependent outgoing session barring flag as ‘ON’. A PT client invited to the PT session restricts the inviting PT client by setting a network dependent incoming session barring flag as ‘ON’. The inviting PT client or the invited PT client can be selectively restricted by using information on operation conditions under which the flags are operated.

8. A method for restricting a push-to (PT) service in a PT service system in which a first PT client invites one or more PT clients and establishes a session, the method comprising:
-
setting network information for restricting a first PT client to invite a PT client existing in a specific network; and
restricting invitation of a PT client satisfying the set network information among invited PT clients. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for restricting a push-to (PT) service in which network information for restricting an invitation with respect to a second PT client which has moved from a first network to a second network is set, the method comprising:
-
receiving, by a first PT server, an invite signal transmitted by the first PT client through a first SIP/IP core;
adding, by the first PT server, the network information into the invite signal and transmitting such to the first SIP/IP core; and
checking, by the first SIP/IP core, a current network of the second PT client and informing the first PT client that session establishment has been stopped if the second PT client belongs to the second network. - View Dependent Claims (23, 24, 25, 26)

27. A method for restricting a push-to (PT) service in which network information for restricting an invitation with respect to a second PT client which has moved from a first network to a second network is set, the method comprising:
-
receiving, by a first PT server, an invite signal transmitted by the first PT client through a first SIP/IP core;
checking, by the first PT server, current network of the second PT client; and
informing, by the first PT server, the first PT client that session establishment has been stopped if the second PT client belongs to the second network. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method for restricting a push-to (PT) service in which network information for restricting connection with one or more PT clients of a second network which have been moved to a third network is set, the method comprising:
-
transmitting, by the first PT client, an invite signal to a first PT server;
adding, by the first PT server, the network information in the invite signal and transmitting it to a second SIP/IP core of the second network; and
informing, by the second SIP/IP core, the first PT client that session establishment with a PT client that moved to the third network has been stopped. - View Dependent Claims (38, 39, 40, 41)

42. A method for restricting a push-to (PT) service in which network information for restricting connection with one or more PT clients of a second network which have been moved to a third network is set, the method comprising:
-
receiving, by a first PT server, an invite signal from the first PT client;
checking, by the first PT server, a current network of the second PT client from the second PT network; and
informing, by the first PT server, the first PT client that session establishment with a PT client that moved to the third network has been stopped. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51)

52. A method for restricting a push-to (PT) service in which network information for restricting an invitation with respect to a client which does not belong to a first network, the method comprising:
-
receiving, by a first PT server, an invite signal transmitted by the first PT client; and
checking, by the first PT server, a Uniform Resource Identifier (URI) of the second PT client, and informing the first PT client that session establishment has been stopped, if the second PT client does not belong to the first network. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59, 60)

61. A method for restricting a push-to (PT) service, the method comprising:
-
transmitting, by a first PT client belonging to a first network, an invite signal to a second PT client belonging to the first network;
establishing a session between the first and second PT clients;
if the second PT client roams to a second network, comparing, by the first network, the current network of the second PT client and pre-set network information;
if the network of the second PT client satisfies the pre-set network information, transmitting by the first network, a release signal to the first and second PT clients. - View Dependent Claims (62, 63, 64, 65, 66)

67. A method for restricting a push-to (PT) service, the method comprising:
-
storing, by a first PT client, network information for restricting invitation to a specific network in a first PT server; and
restricting, by the first PT server, an invitation when an inviting network satisfies the set network information. - View Dependent Claims (68, 69, 70, 71)

72. A method for restricting a push-to (PT) service in which network information for restricting a first PT client of a first network from being invited to a second network is set, the method comprising:
-
receiving by a first PT server an invite signal from the second network;
comparing by the first PT server the network information and information of the second network, and informing the second network that session establishment has been stopped if the information of the second network satisfies the network information. - View Dependent Claims (73, 74, 75, 76, 77)

78. A method for restricting a push-to (PT) service of a PT system in which a network-dependent outgoing session barring flag and operation condition information is set for a PT server to restrict an invitation with respect to specific PT clients, wherein,
when an outgoing session barring override flag transmitted through a terminal by a user is set, a session is established regardless of the set outgoing session barring flag and operation condition information.

81. A method for restricting a push-to (PT) service, the method comprising:
-
setting a PT session establishment condition in an application server;
receiving by the application server a request for PT session establishment and comparing the session establishment condition with a current session establishment state; and
selectively performing a session connection according to the comparison result. - View Dependent Claims (82, 83, 84)
