20080247373 | MULTICAST PUSH TO TALK GROUPS, APPARATUS, AND METHODS - A terminal (such as that belonging to or carried by an emergency first responder, for example) participates in a push to talk multicast group in either of two modes or levels. In a first mode or first level of participation, the terminal can join a multicast address for the push to talk multicast group as a passive recipient of transmissions and can thereby listen to the multicast address. In a second mode or second level of participation, the terminal becomes an active participant in the push to talk session. As an active participant in the push to talk session, the terminal can, e.g., receive sender identification (e.g., identification of other participants who may be talking in the push to talk multicast group) and send media bursts to the multicast group. | 10-09-2008 |

20090055473 | Message and arrangement for provding different services in a multimedia communication system - 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 ( | 02-26-2009 |
20090168696 | METHOD AND ARRANGEMENT FOR ESTABLISHING A COMMUNICATION SESSION FOR MULTIMEDIA - A method and arrangement for establishing a packet-switched multimedia session for a mobile terminal (A) in communication with another party (B), wherein a primary PDP (Packet Data Protocol) context has been activated in a mobile network for the mobile terminal. Information on the forthcoming session is received which has been negotiated and agreed between the communicating parties. It is then determined whether any network resources providing a required QoS are needed for the session, and whether a secondary PDP context is to be activated for the mobile terminal and the forthcoming session. If network resources are needed and a secondary PDP context is to be activated, the activation of said secondary PDP context is triggered. | 07-02-2009 |
20100142412 | METHOD FOR SYNCHRONIZING THE PRESENTATION OF MEDIA STREAMS IN A MOBILE COMMUNICATION SYSTEM AND TERMINAL FOR TRANSMITTING MEDIA STREAMS - 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 ( | 06-10-2010 |
20100202291 | Method of Selecting Media Flow - In a method and a system for handling a request for a service or a media flow from a user of a cellular radio system, means are provided for deciding if an already existing PDP context or EPS Bearer is to be used for the requested service or media flow based on information received from the system. | 08-12-2010 |
20100220604 | METHOD AND ARRANGEMENT FOR ESTABLISHING A COMMUNICATION SESSION FOR MULTIMEDIA - 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. | 09-02-2010 |
20100316001 | Method of Transmitting Synchronized Speech and Video - In a method and mobile station for transmitting speech data over a packet data connection and video-data over a packet switched connection information about the rendering and capturing clocks for both a Circuit switched (CS) speech connection and a Packet Switched (PS) video connection are determined by a transmitter. The information is transmitted to a receiver and the receiver uses the information to enable synchronization between the speech connection and the video connection. | 12-16-2010 |
20100322122 | BUNDLING OF SPEECH FRAMES IN CS OVER HSPA NETWORKS - In a method and mobile station for transmitting speech data over a packet data connection a number of speech data frames are bundled into to a bundled frame, which is transmitted over a packet data connection. Hereby the time when the transmitter needs to transmit can be reduced which in turn will reduce the energy required for transmitting speech data. Hereby the battery life time can be increased. The bundling in accordance with the present invention can advantageously be used when transmitting speech data over a High Speed Packet Access. HSPA. connection. | 12-23-2010 |
20110110245 | Code Assignment in HS-SCCH Less Operation Mode - In a method and a system a good spread of users per code is obtained by providing a value related to the current load for each code in the system. The estimated load value can be used by the network to assign the HS-PDSCH code for users in HS-SCCH less operation, and may also be used in the dynamic transmission process, i.e. which codes are to be used by which user during this and future TTIs. If one code is over a given utilization threshold, where the threshold is set in order to avoid code blocking of VoIP users, enough users can be re-assigned to a different code. In the case that all of the current codes used in the HS-SCCH less operation model are over the utilization threshold, yet another code can be made available for HS-SCCH less operation. | 05-12-2011 |
20110149852 | KEEPING PACKET SWITCHED SESSION IN LTE WHILE CIRCUIT SWITCHED REGISTERED IN WCDMA - A wireless terminal, when already having a registration and/or session for a packet switched (PS) service with a Long Term Evolution (LTE) core network, makes a registration for a circuit switched (CS) service over a Wide Band Code Division Multiplexing (WCDMA) air interface with a circuit switched (CS) core network, but in conjunction with the registration for the circuit switched (CS) service maintains the registration and/or session for a packet switched (PS) service with the Long Term Evolution (LTE) core network. | 06-23-2011 |
