Abstract:
A method controls group communication in a communication network. The method includes sending, to a plurality of users, requests to join a group communication session. The method also includes detecting that at least one of the users was not accepting the request to join the group communication. The method also includes subscribing to a status of the at least one of the users not joining the group communication session. The status may be a registration status or a presence status.
Abstract:
The present invention relates to a session handling entity in a communication system, the session handling entity (S-CSCF) maintain a relationship between at least one public user identity, at least one private user identity and at least one contact address of a user of a communication system. Then receives from a subscription entity an indication of a correlation identity associated with the user, and stores the indication of the correlation identity as part of the relationship maintained by the maintaining means. When a session request of the user is received, determining the correlation identity for the user based on a contact address of the user included in the session request and the indication of a correlation identity associated with the user take place, and the correlation identity is included in the session request.
Abstract:
There is proposed a method and corresponding apparatuses allowing a change from a packet switched communication domain to a circuit switched communication domain. When a user equipment as a connection terminating point receives a connection initialization message with a media flow, such as audio, which cannot be delivered by the packet switched access, it sends a specific response rejecting the connection via the packet switched access to an application server for service centralization and continuity. In the application server, it is checked whether several conditions are met in order to determine whether the communication connection comprising the media flow is allowed to be changed to the circuit switched domain. If yes, the communication connection is changed from the packet switched communication domain to the circuit switched communication domain.
Abstract:
A group detail indicator is provided that relates to group communication in a communication system. The group detail indicator provides information on at least an identity of a group and a type of the group. The group detail indicator also is attached to one of a request to initiate a group communication session and an instant messaging request.
Abstract:
Disclosed is a method including having an ongoing communication session via a packet switched network, transferring said communication session from the packet switched network to a second network providing both packet and circuit switched access, and informing an application server maintaining said ongoing communication session that the communication session is to be split into a packet switched part and a circuit switched part. Also disclosed is a method in an application server, including receiving, from a first communication device, an indication that a communication session between the first communication device and a second communication device is to be split into a packet switched part and a circuit switched part, waiting for to receive transfer requests of both the packet switched part and the circuit switched part, and informing the second communication device of the split.
Abstract:
A method of managing chat services in a communications system comprising the steps of: a first user terminal initiating a chat session with a session manager; said first user terminal inviting a second user terminal to join the chat session, wherein the second user terminal is associated with a blocklist of blocked users that are blocked from communicating with the second user terminal; checking if a third user terminal invited to join the chat session by the first user terminal is listed in the blocklist; and in the event that the third user terminal is in the blocklist, creating a notification message to notify a user of the second user terminal that a blocked user is joining the chat session.
Abstract:
A way to provide page-mode messaging is to send a message using a session-mode messaging mechanism with an indication indicating that the session-mode is for a pager-type message. In response to said indication, a receiver treats the message as a page-mode message although it was received in the session-mode.
Abstract:
Disclosed is a method in an application server. A request for initiating a communication session is received, and responsive to the request including a first service identifier pertaining to a service not supported by the application server, the first service identifier is removed from the request. A response to the request is received, and responsive to having removed the first service identifier from the request and the response including a second service identifier pertaining to the same service as the first service identifier, the second service identifier is removed from the response.
Abstract:
A device is described which comprises a sender and a receiver configured to perform a circuit switched session, wherein the sender and the receiver are capable to also send and receive session control messages according to a session control protocol, and a controller configured to receive a specific session control message, wherein the session control message includes information for establishing a specific packet switched connection capable of supporting a specific packet services to a network node, wherein the information is encoded in a format suitable for the session control protocol, wherein the controller is further configured to obtain the information from the specific session control message, and to establish the specific packet switching connection based on the obtained information.
