The invention relates to method applicable in a packet-switched cellular network for voice connections, by which method a new dedicated channel can be established quickly using the existing dedicated channel of the voice connection. The establishment of the new dedicated channel utilizes the previous dedicated channel the existence of which is extended by sending to at least the receiving terminals post-speech packets according to the invention. The post-speech packets produce a 2-second delay, approximately, which is sufficient to establish a new dedicated channel between terminals participating in a session.

A communication method, a mobile terminal and a computer program are provided. According to the invention, data streaming communication is performed to the mobile terminal, a communication connection request message is received from the network infrastructure in the mobile terminal, the reception of the communication connection request is indicated to a user of the mobile terminal, a first mode change command generated by the user is received in the mobile terminal, suspension of the data streaming communication is requested for on the basis of the first mode change command, and the communication connection is accepted on the basis of the first mode change command.
摘要:
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.
摘要:
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.
摘要:
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.
