Abstract: A method and arrangement for distributing services messages from a client terminal to multiple service units or applications in one or more application servers in a multimedia service network. A service message distributor receives from the terminal, a multi-service message that includes a plurality of service message documents containing service-related data targeted to a specific service unit or application. The message distributor converts the received message into a plurality of individual service messages corresponding to the documents. The individual messages are sent separately toward their respective target service units or applications.

Abstract: A method of handling the delivery of push messages from a notification server of a Session Initiation Protocol based network to a network user. The method comprises signalling to said notification server the start of a Session Initiation Protocol session and the end of a Session Initiation Protocol session, and deferring the delivery of some or all push messages, scheduled for delivery to said user during the ongoing session, until the session has finished.

Abstract: A method and apparatus for distributing load between a plurality of servers, for handling incoming service requests in a server system. When a service request in received in an access node, a primary server is assigned out of a set of primary servers, using a first scheduling algorithm, for performing a processing task for the received service request. The first scheduling algorithm is capable of selecting any primary server. Further, a secondary server is assigned out of a set of secondary servers, using a second scheduling algorithm, for performing a storing task for the received service request. The second scheduling algorithm is capable of selecting one specific secondary servers for a storing task.

Abstract: A method and apparatus for dynamically reconfiguring a server system. When a new server configuration is applied, a previous server configuration is saved. When receiving a service request, a first server is selected by using a first scheduling algorithm according to the new configuration. If the selected server is incorrect, a second server is selected by using a second scheduling algorithm according to the saved previous server configuration. User data associated with the received service request is moved from the second server, if correct, to the first server. In this way, stored data will be gradually and dynamically reorganized from the previous configuration to the new configuration in a relatively simple way.

Abstract: A method and arrangement for handling incoming requests for multimedia services in an application server having a plurality of processors. A service request is received from a user, requiring the handling of user-specific data. The identity of the user or other consistent user-related parameter is extracted from the received service request. Then, a scheduling algorithm is applied using the extracted identity or other user-related parameter as input, for selecting a processor associated with the user and that stores user-specific data for the user locally. Thereafter, the service request is transferred to the selected processor in order to be processed by handling the user-specific data.

Abstract: A method and arrangement for handling client-related information in an application server connected to a telecommunication network for a client that has registered with the network. The application server receives a message from the client that results in the activation of a client state in the server. The server then creates a subscription with a registration unit such as an S-CSCF for monitoring registration events when the client's registration is changed. When the application server receives a registration event notification from the registration unit, the server updates the client state in response thereto.

Abstract: A method and arrangement for making membership information in communication groups easily available to clients. A group management server (202A) receives a group creation request (2.1) from a first client (A) for a new group comprising at least a second client (B). A list (Li) of members in the group is then stored (2.2), and a group event notification (2.3) is sent to a home network (200B) of the second client, to inform the network that the second client has become a member in the new group. A client can then find out which active communication groups he/she is a member of, without elaborate searching.

Abstract: The invention enables efficient management of messages in a communication system. A messaging center (100) generates, in response to reception of a request message from a first user (200) and intended to a second user (300), transaction information. This information is stored in a database (180) together with an identifier of the first user (200). A temporary address is generated based on the transaction information and an identifier of the center (100). A second request message including the temporary address is transmitted to the second user (300). Due to careful choice of the temporary address, the second user (300) may easily transmit a response message to the center (100). Upon reception, the center (100) extracts the temporary address from the response message and extracts the transaction information from the address.

Abstract: A method and apparatus for dynamically reconfiguring a server system (200). When a new server configuration is applied, a previous server configuration is saved. When receiving service requests, a first server is selected by using a first scheduling algorithm according to the new configuration. If the selected server was incorrect, a second server is selected by using a second scheduling algorithm according to the saved previous configuration. User data associated with the received service request is moved from the second server, if correct, to the first server. In this way, stored data will be gradually and dynamically re-organised from the old configuration to the new configuration in a relatively simple way.

Abstract: Alternate speech and data communication over a single circuit is implemented within a communication network which include first nodes which include both a data source and a speech source. Digital information, comprising either speech parameters or data, is sent in discrete blocks between the first node and a second node connected to the network. An inband signaling bit pattern is included within selected blocks sent by a TX-alternator in the sending node to indicate whether all following digital information is to be interpreted by the receiving node as speech or data and a RX-alternator in the receiving node interprets the digital information in accordance with the last received inband signaling pattern. One exemplary implementation is in a GSM cellular radio network in tandem free operation.
