US 6,788,673 B1 · Method for connecting telephone calls in a mobile communication system

Abstract

The invention relates to a method for answering a phone call coming to a mobile terminal in a situation where a packet-switched connection is active in the mobile terminal. At least one reference item (PN, UN, GNO, CL1) has been saved in the mobile terminal. The method comprises a reception step, wherein information about an incoming call is received to the mobile terminal (MS). The method also comprises at least an examination step, wherein received information about a phone call is examined in a mobile terminal (MS) for finding at least one item of caller line identification (CLI), and it is examined whether reference items (PN, UN, GNO, CL1) have been saved in the mobile station (MS). Then, if at least one reference item (PN, UN, GNO, CL1) has been saved, a comparison step is carried out in the method, in which step said at least one reference item (PN, UN, GNO, CL1) is compared to said at least one item of caller line identity information (CLI) discovered in the examination step. After that, a decision step is carried out in the method, in which step it is decided whether the call is answered or not. The decision is made on the basis of the comparison performed in said comparison step, if a comparison step was carried out.

A method for answering a telephone call coming to a mobile terminal (MS) in a situation where there is a packet-switched connection active in the mobile terminal (MS), into which mobile terminal (MS) at least one reference item (PN, UN, GNO, CL1) can be saved, and in which method a reception step is carried out, during which information about the incoming telephone call is received to the mobile terminal (MS), characterised in that the method also comprises at least the following steps:

the examination step, in which the information received about a telephone call is examined in the mobile terminal (MS) in order to find at least one item of caller line identity information (CLI), and to find out whether at least one reference item (PN, UN, GNO, CL1), has been saved in the mobile terminal (MT), whereby if at last one reference item (PN, UN, GNO, CL1), has been saved, a comparison step is carried out in the method, wherein said at least one reference item (PN, UN, GNO, CL1) and said at least one item of caller line identity information (CLI) discovered in the examination step are compared, and
a decision step in which the decision about answering the phone call is made, and which decision is based on the comparison performed in said comparison step, if the comparison step was carried out.

A mobile terminal (MS), which comprises means (RF) for answering the incoming call in a situation where there is a packet-switched connection active in the mobile terminal (MS), which mobile terminal (MS) comprises means (MEM) for saving at least one reference item (PN, UN, GNO, CL1), and means (RF) for receiving information (CLI) associated with the incoming call, characterised in that the mobile terminal (MT) also comprises at least:

examination means (CONTROL, DB1) for finding at least one item of caller line identity information (CLI) from information received associated with the incoming call,
comparison means (CONTROL, DB1) for comparing at least one reference item (PN, UN, GNO, CL1) with at least one item of caller line identity information (CLI) discovered in the examination means and for producing a comparison result, and
decision means (CONTROL) for making the decision about answering the phone call on the basis of the comparison result produced by the comparison means.

A data transfer system (NW1) comprising means (SGSN, GGSN) for establishing a packet-switched connection between a mobile communication network (NW1) and a mobile terminal (MS), means (MSC) for initiating a telephone call between the mobile communication network (NW1) and the mobile terminal (MS), means (MSC, PSTN) for associating at least one item of caller line identity information (CLI) with the telephone call, and means (MEM) for saving at least one reference item (PN, UN, GNO, CL1), and which mobile terminal (MS) comprises means (RF) for answering an incoming call in a situation where a packet-switched connection is active in the mobile terminal (MS), characterised in that the data transfer system (NW1) also comprises at least:

examination means (CONTROL, DB1) for finding at least one item of caller line identity information (CLI) from information received associated with the incoming call in the mobile terminal (MS),
comparison means (CONTROL, DB1) for comparing at least one reference item (PN, UN, GNO, CL1) with the at least one item of caller line identity information (CLI) discovered in the examination means and for producing a comparison result, and
decision means (CONTROL) for making the decision about answering the phone call in the mobile terminal (MS) on the basis of the comparison result produced by the comparison means.
