Abstract: A session set-up for communicating data via a data network is disclosed. First, a session establishment between a communication apparatus and a serving entity is requested for a service from the serving entity supporting the service. Then, when a requirement of a user connection for the service is determined, an association with a data network for the service is activated via a core network.

Abstract: A method, apparatus, and computer program product are provided for page-mode messaging. The method includes determining whether a page-mode message exceeds a predetermined size limit. The method further includes sending, using a terminal, the page-mode message using a session-mode messaging mechanism when it is determined that the page-mode message exceeds the predetermined size limit, with an indication indicating that a session-mode is for the page-mode message. Further, the method includes applying, using the terminal, a session description protocol to initiate a session in the session-mode messaging mechanism, and adding, using the terminal, the indication to a header of a session initiation message.

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: The invention relates to a method for ensuring the adequacy of transmission capacity in a digital packet-switched cellular network where both voice sample packets and associated header fields are transmitted in real time in one and the same transmission channel. The invention also relates to a terminal employing the method. In the method, the contents of voice sample packets at the beginning of a speech spurt are partly replaced by packet header field data in situations where the combined bit count of voice sample data and packet header data exceeds the transmission capacity of the transmission channel.

Abstract: A data transmission method transmits data to a group of receiving communication devices in a communication system comprising at least one cellular network. The method includes defining, by an application server situated beyond a cellular network, a group of receiving communication devices in the cellular network, the application server having no visibility to locations of receiving devices in the cellular network. The method also includes receiving, in a broadcast/multicast network entity configured to provide broadcast and multicast services in the cellular network, data to be transmitted from the application server to the group. The method also includes transmitting the data from the broadcast/multicast network entity to the group using broadcast and/or multicast transmission. Furthermore, a network entity in a cellular network and a communication system are provided configured to implement the method.

Abstract: A method enables obtaining parameters relating to a service provided in a communication system. The method comprises storing a first set of parameters relating to a service, the first set of parameters being valid when the service is controlled by a first network. The method further comprises determining whether a second set of parameters is needed, the second set of parameters relating to said service and being valid when said service is controlled by a second network. The method further comprises obtaining the second set of parameters, when needed. A communication device is configured to execute the method.

Abstract: The invention relates to a protocol converter (14) and a method utilizing the converter, enabling a wireless connection (13) between a cellular network (11) and a terminal to apply a reduced RTP protocol according to the invention, instead of the RFC 1889 protocol, in order to save communications capacity on speech connections.

Abstract: The invention relates to a method and subscriber equipment of controlling transmission power in the transmitter. The subscriber equipment transmits bursts with different activity. The subscriber equipment forms an average activity of the transmitter, and controls transmission power of the bursts as a function of the average activity of the transmitter.

Abstract: A user terminal requesting a session establishment although the session already exists, is informed on the existing session in a response to the request. If the user terminal offered in the request one or more media types that were rejected, the response contains an indication of a reason for rejection.

Abstract: In order to facilitate group communication using characteristics of a pre-arranged group but not involving all members of the pre-arranged group, a parameter indicating that the group communication is not intended to all members of the pre-arranged group is added by an inviting group member sending a request to a group server, and the group server, in response to the parameter, is configured to not to invite all members to the group communication.

Abstract: An application server for controlling communication of packet data with a plurality of communication devices in a multicasting session is disclosed. The application server is configured for receiving information regarding a packetization parameter that is desired by at least one of the communication devices for reception of packet data, for assigning a different value for the packetization parameter for use in a multicasting session, and for controlling communication of packet data to the plurality of communication devices in the multicasting session based on the different packetization parameter.

Abstract: A system for presence publication, such as in a push-to-talk over cellular service, provides means for avoiding the reporting of conflicting presence information to a presence server. Two different entities may be capable of reporting status information for the same entity, the status information corresponding to a plurality of status attributes. The first entity would typically inform the second entity which ones of the plurality of status attributes for which the first entity will be reporting status information to the presence server. For the ones of the plurality of status attributes for which the first entity will be reporting status information, the second entity will typically not report status information. For the ones of the plurality of status attributes for which the first entity will not be reporting status information, the second entity will typically report status information if capable.

Abstract: A method of group communication in a system where clients need to request floor access from a controlling network element includes a controlling network element that determines a floor access control situation where number of floor access requests should be limited and sends a session-specific indication on the floor access control situation to the client. The indication includes a priority statement that the client compares to its own priority. If the assigned priority does not match with the priority statement, the client refrains from sending floor access request.

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: A controller for controlling a multiparty session in a communication system and a method for is disclosed. The controller comprises a control function configured to host a multiparty session. The control function controls joining of parties to the multiparty session and also selects at least one communication parameter based on discovered capabilities of the parties to the multiparty session. After the selection, information regarding the selected at least one communication parameter is sent to at least one party of the multiparty session.

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.
