摘要： In current multimedia communication systems using session initiation protocols such as SIP, a service change (e.g. adding a new media type to an existing multimedia conversation) entails significant delays and processor load in both clients and server. The current invention solves this by separating session signaling and media control signaling in different signaling channels (141,142) and by eliminating the need to re-establish SIP sessions for each service change. The application server (120) maintains a list of all media types supported by each multimedia client (110) involved in a multimedia conversation. Each multimedia client (110) requesting to send one or several media streams with different media types to one or several other multimedia client(s) negotiates with the application server (120) only. The inventive concept significantly reduces networks delays and speeds up the service change as perceived by the user. The invention is of interest for various multimedia conferencing applications.
摘要翻译：在使用诸如SIP之类的会话发起协议的当前多媒体通信系统中，服务改变（例如，将新媒体类型添加到现有多媒体对话中）在客户机和服务器中都需要显着的延迟和处理器负载。本发明通过在不同信令信道（141,142）中分离会话信令和媒体控制信令来解决这个问题，并且通过消除对每个服务改变重新建立SIP会话的需要。应用服务器（120）维护涉及多媒体会话的每个多媒体客户端（110）支持的所有媒体类型的列表。请求向一个或多个其他多媒体客户端发送具有不同媒体类型的一个或多个媒体流的每个多媒体客户端（110）仅与应用服务器（120）协商。本发明的概念显着地减少了网络延迟并加快了用户感觉到的服务改变。本发明对于各种多媒体会议应用是有意义的。

摘要： For some mobile communication services, a media stream such as video, will be combined with another media stream such as voice. For example, a user of a first terminal (101) is involved in a voice call over e.g. a circuit switched network (103) with a friend. During the voice call, the user of the first terminal decides to start transmitting another media stream, such as live streamed video, which may be transmitted over a packet switched network (104), to the friend's terminal (102). In such a case there is problem in that the two media streams voice and video may have quite different end-to-end time delays, i.e. the time from a part of the media stream is transmitted from the first user's terminal (101) until that part of the media stream is presented at the friend's terminal (102). Since comments from the first user will be presented to the user's friend earlier than the commented part of the video this will be quite annoying to the friend. To avoid this problem this invention presents the video to the user of the first terminal (101) delayed with a time dependent on the time difference between the end-to-end time delay of video and the end-to-end time delay of voice. Thereby, comments from the user of the first terminal (101) regarding the video will be received at the friend's terminal (102) approximately synchronized with the video.
摘要翻译：对于一些移动通信服务，诸如视频的媒体流将与诸如语音的另一媒体流组合。例如，第一终端（101）的用户参与例如语音呼叫。与朋友的电路交换网络（103）。在语音呼叫期间，第一终端的用户决定开始发送可以通过分组交换网络（104）发送的另一媒体流，诸如直播流视频，到朋友的终端（102）。在这种情况下，存在两个媒体流语音和视频可能具有非常不同的端到端时间延迟的问题，即，来自媒体流的一部分的时间从第一用户的终端（101）发送到该时间延迟媒体流的一部分呈现在朋友的终端（102）。由于来自第一个用户的评论将会在视频的评论部分之前提交给用户的朋友，这对朋友来说是相当烦人的。为了避免这个问题，本发明向第一终端（101）的用户呈现视频，其延迟时间取决于视频的端到端时间延迟与语音的端到端时间延迟之间的时间差。因此，与第一终端（101）的用户关于视频的评论将在朋友的终端（102）处接收，与视频大致同步。

摘要： A method and arrangement for establishing a packet-switched multimedia session for a mobile terminal connected to a mobile access network. A first Radio Access Bearer RAB is obtained, and the multimedia session is started by communicating media over the first RAB. Simultaneously with the media communication, a quality of communicated media is monitored and evaluated. If the monitored quality is deemed unacceptable, a media-adapted second RAB is obtained, and the session is continued over the second RAB. Thereby, it is not necessary to delay the communication of media by waiting for the second RAB to be obtained.
摘要翻译：一种用于为连接到移动接入网络的移动终端建立分组交换多媒体会话的方法和装置。获得第一无线电接入承载RAB，并且通过在第一RAB上通信媒体来启动多媒体会话。在媒体沟通的同时，对传播媒体的质量进行监控和评估。如果监视的质量被认为是不可接受的，则获得媒体适配的第二RAB，并且会话在第二RAB上继续。因此，不需要通过等待获得第二RAB来延迟媒体的通信。

摘要： A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer of the client device.

摘要： Interoperability is achieved between wireless user communication devices that have different speech processing formats and/or attributes. A first wireless user communication device includes a primary speech codec that encodes a first speech message using a first speech encoding format. The encoded speech is then sent to a second wireless user communications device that includes a primary speech codec supporting a second speech encoding format. The first user device receives from the second user device a second speech message encoded using the second speech encoding format. The second speech message is then decoded by the first user device using a second speech decoder supporting decoding of the second speech encoding format. But the first communication device does not support speech encoding using the second speech encoding format—regardless of whether the first communication device includes or does not includes an encoder for encoding speech using the first speech encoding format.

摘要： A radio network controller is operable in both a unicast signaling mode and a bi-cast signaling mode. In unicast signaling mode, the radio network controller is operable to send radio resource control signals to a mobile station through a serving cell. The radio network controller is operable to go into bi-cast signaling mode during a hard handover. In the bi-cast signaling mode, the radio network controller is operable to send radio resource control messages to the mobile station through both the current serving cell and a target cell. The mobile station is configured to listen to both the current serving cell and the target cell for radio resource control messages. User data, however, is transmitted only from the current serving cell to the mobile station.

摘要： A method and application server for providing different services and performing service changes in a multimedia communication system. When a first client invites a second client to join a multimedia session, the server learns which media types are supported by each client, including first and second media types supported by the server. The first client then sends the server a request on a media control channel to transmit media of the first and second types. The server verifies the requested media types are supported by the second client and sends the first client a grant for the requested media types. The server receives a first media burst of the first media type from the first client and retransmits the burst to the second client, and then receives a second media burst of the second media type from the first client and retransmits the burst to the second client.

摘要： A telecommunications network (10) comprises a group call service server (18) which facilitates a group call over a radio interface (32) between different user equipment units (30) in a defined group within the telecommunications network. The group call service server (18) receives a floor request from a requesting user equipment unit (32j) included in the group, and handles the floor request based on a media type associated with the floor request. In conjunction with such handling, in one aspect of its operation the group call service server prioritizes the floor request from the user equipment unit based on the media type (e.g., based on delay sensitivity of the media type associated with the floor request). In one example implementation, the group call service server comprises a queue (42) and a floor request handler (40). The group call service server queues the floor request from the requesting user equipment in the queue (42); the floor request handler (40) prioritizes the floor request within the queue based on the media type. In a specific example implementation, the group call service is Push-to-Talk over Cellular (PoC) and the group call service server comprises PoC server situated in a service network. Also provided are a group call service which handles the floor request based on a media type, and a message format for the floor request itself.
