  • Patent number: 8774872
    Abstract: Methods and devices for providing a ring signal to a called party terminal (450, 550, 650, 750, 124, 134) for a call from a calling party terminal (400, 500, 600, 700, 120, 130) to the called party terminal for alerting the called party regarding the call from the calling party. A communication network node (420, 520, 620, 720, 122, 132, D90) receives (S100) an indication of an attempt for the call and sends (S110) a ring signal specified by the calling party at a service node (430, 530, 630, 730, 125, 135, D100) of a calling party ring signal service to the called party terminal for alerting the called party regarding the call from the calling party.

  • Patent number: 8731566
    Abstract: The invention discloses a method (500) for a cellular communications network (100), according to which there can be a plurality of users (110, 120) in the network; said network comprises control functions (NodeB, RNC, MSC, HLR) for receiving, connecting and directing traffic to and from users. According to the method (515), at least a number of said users are associated with individual user identities which are unique in said network, and least two addresses such as numbers which may be used by a first user (110) in order to establish communication with a second user (120) in the network are mapped (525) to the unique user identity which is held by the second user, so that the entering or dialling of either of said at least two addresses by said first user will result (540) in an attempt by the network to establish communication with the second user.
