Definitions
- the present invention relates to a method as defined in the preamble of claim 1 and to a system as defined in claim 13 for implementing a call back function in a public telephone network (PSTN, Public Switched Telephone Network) or mobile subscriber network (PLMN, Public Land Mobile Network) .
- PSTN Public Switched Telephone Network
- PLMN Public Land Mobile Network
- GSM Global System for Mobile Communications
- the called subscription when the called subscription is busy, it may be informed about a new incoming call e.g. via a call waiting function.
- the called sub- scriber may alternate between active calls using certain commands.
- One alternative is naturally to try calling again later.
- utilizing the call waiting function queueing up or trying again later as mentioned above is not always an adequate solution for the situation.
- a call back function working on a similar principle can be implemented in the wired telephone network e.g. in conjunction with a telephone switchboard.
- the switchboard functions as an "intelligent" network component and waits until the called subscriber hangs up. After this, the switchboard sets up a speech connection between the subscriber who has been trying to set up a call and the called subscriber.
- CCBS Chip Completion to Busy Subscriber
- MSC mobile switching centre
- the object of the present invention is to eliminate the drawbacks referred to above or at least to significantly alleviate them.
- a specific object of the invention is to disclose a new type of method and system in which a CCBS service can be implemented independently of the mobile service standard and the local exchange and terminal equipment .
- an A- subscription (calling subscriber) is setting up a call to a busy B-subscription (called subscriber) .
- the A- subscription is given an announcement and/or a menu, on the basis of which the A-subscriber selects a desired service.
- a command for turning on a service e.g. call back
- the command is transmitted in the telephone network to a network service node (SN) , which identifies it.
- SN network service node
- the network service node continues trying to set up a connection to the B-subscription until the latter is on-hook or until some other kind of time-out is tripped.
- the service node sets up a connection to the A- subscription after call setup to the B-subscription has been successfully completed. After this, the network service node is ready to establish a speech connection between the A-subscription and the B- subscription.
- an operator can implement a service that improves its readiness to serve its customers.
- the invention can be easily and advantageously implemented in any telephone and/or mobile subscriber network.
- the A-subscription trying to set up a speech connection activates the call back function by means of a certain predetermined tone frequency (DTMF, Dual Tone Multi-Frequency) signal, and the A-subscription is given notice of the activation of the call back function.
- DTMF Dual Tone Multi-Frequency
- the B-subscription is also in- formed about the call back.
- attempts to set up a connection to the B-subscription are repeated by the service node during a predetermined maximum length of time. Further, in a preferred embodiment of the invention, the time interval between call setup attempts made from the network service node to the B- subscription is changed and, moreover, call setup attempts made from the service node to the B- subscription are stopped after the lapse of a certain length of time.
- the commands and/or menus used between the service node and the telecommunication terminals are generated by using USSD (USSD, Unstructured Supplementary Service Data) .
- the commands and/or menus used between the service node and the telecommunication terminals are generated by using WAP (WAP, Wireless Application Protocol) .
- WAP Wireless Application Protocol
- the commands and/or menus used between the service node and the telecommunication terminals are generated by using SMS (SMS, Short Message Service) .
- each service in a service menu there is a given tone frequency signal corresponding to the service .
- a preferred embodiment of the system of the invention for implementing a call back function in a telephone network comprises a network service node, a first telecommunication terminal and a second telecommunication terminal .
- the service node is capable of receiving a command sent by the A-subscription, and it comprises means for setting up a connection to the B- subscription, for setting up a connection to the A- subscription and means for establishing a connection between the two call legs started by the service itself.
- the first and second telecommunication terminals comprise means for sending tone frequency signals.
- the service node comprises means for receiving control signals coming from the A-leg.
- the network service node comprises means for identifying tone frequency signals and, moreover, the service node comprises means for giving notice of an activated service.
- the telecommunication terminals comprise means for handling USSD messages and/or SMS messages and/or WAP messages.
- the service node comprises means for handling USSD messages and/or SMS messages and/or WAP messages .
- the present in- vention has the advantage that the service implemented is independent of the network signalling used in the mobile subscriber network and/or telephone network.
- the service is independent of the terminal and/or radio interface.
- a further advantage can be recognized in the fact that the calling subscriber avoids useless re-attempts to set up a connection.
- Fig. 1 presents an embodiment of the system of the present invention
- Fig. 2 presents a signal flow diagram illustrating the principle of call back according to an embodiment of the present invention.
- Fig. 1 represents a system according to the present invention, comprising a mobile subscriber network MSN and, connected to it, a first mobile station 1 and a second mobile station 2.
- the mobile subscriber network MSN comprises a service node SN with a first mobile switching centre 4 (MSC) and a second mobile switching centre 5 connected to it.
- the first 1 and second 2 mobile stations comprise means 12 for sending tone frequency signals.
- the service node 3 comprises means 6 for receiving a command coming from the A- subscription, means 7 for setting up a connection to the B-subscription, means 8 for setting up a connection to the A-subscription and means 9 for setting up a connection between the A and B subscriptions.
- the service node 3 comprises means 10 for identifying tone frequency signals and means 11 for giving notice of an activated service.
- the telecommunication terminals 1 and 2 comprise means 12, 14 and 16 for handling USSD and/or SMS and/or WAP messages.
- the service node 3 comprises means 13, 15 and 17 for handling USSD and/or SMS and/or WAP messages.
- Fig. 1 are implemented in a manner known in itself, e.g. using program blocks and computers, and they will therefore not be described here in detail.
- Fig. 2 presents an example of a signal flow diagram representing a call back function as provided by the invention.
- A-subscription 1 a call setup attempt (20,21) is sent to a B-subscription 2 in a mobile subscriber network.
- the call setup request is routed from a mobile switching centre 4 as presented in Fig. 1 to the service node 3 in charge of call setup requests made from the A-subscription and/or those addressed to the B-subscription.
- the service node 3, as presented in Fig. 1 transmits the call setup request to mobile switching centre 5, which directs the call setup request to the B-subscription 2 to be reached.
- a busy signal As the B-subscription 2 is busy, a busy signal, arrows (22) and (23), is sent to the network service node 3 and further to the A-subscription 1.
- a service menu (24) is sent to the A- subscription 1.
- a desired service in this example call back, is selected from the A- subscription 1.
- a command (25) for the activation of call back is sent from the A-subscription 1 to the service node 3.
- a corresponding notice (26) is sent from the service node 3 to the A-subscription 1.
- the service node 3 starts setting up a call (27) to the B-subscription 2.
- the B-subscription is still busy (28) and sends a busy signal back to the service node 3.
- a new attempt to set up a call (29) to the B-subscription 2 is made. This time, the B-subscription is on-hook (30) and a corresponding signal is sent back to the service node 3. At the same time, a notice (31) regarding call back is sent to the B-subscription.
- the service node 3 now starts call setup (32) to the A-subscription 1.
- the A-subscription 1 is also on-hook (33) , so a speech connection (34) can be set up between the subscriptions.
