摘要:
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.

A method of operating a base station node (21) comprises obtaining an indication of degradation of a radio link connection between the base station node and the user equipment unit (UE) which is carried by the a high speed packet channel (HSDPA). In accordance with the distance indication, the transmission priority for the radio link connection is modified. Preferably the indication of degradation is a distance indication of distance of a user equipment unit (23) involved in the radio link connection from the base station node (21). The transmission priority can be modified for one or both of downlink and uplink transmissions for the user equipment unit (UE). Preferably the transmission priority is modified for the radio link connection, e.g., for the user equipment unit (UE), as a function of the indication.

A Multimedia system and a method in a Multimedia system where a first user with user equipment (1) uses a Push to talk service (PTT) to communicate with at least one second subscriber's user equipment (2) using said Push to talk service (PTT), wherein a PTT-server (3) providing the PTT-service interacts with said first and second subscriber's user equipment (1, 2) and exchanges information concerning relevant parameter values for each user equipment (1, 2), and each user equipment (1, 2) adapting its application settings during the operation of said PTT-service, whereby degradation of the perceived quality is prevented
摘要:
A terminal (30, 30B) receives transmissions in a form of a media stream. The terminal comprises a jitter buffer (40) which receives data comprising the media stream and a buffer manager (80). The buffer manager (80) makes a selection between plural playback pointers as an operative playback pointer from which the data comprising the media stream is played out of the jitter buffer. In an example implementation, the buffer manager (80) updates at least one of the plural playback pointers. The manner and timing of the updating of the least one of the plural playback pointers can occur in any of a variety of ways. The terminal (30, 30B) can take various forms, and may be (for example) either a wireless terminal which receives the media stream across a radio interface, or a wireline terminal.

Embodiments herein include a method in a server for scheduling of an information transmission from an information providing device to a subscriber equipment in a communication system. The method comprises determining a moment in time at which the subscriber equipment desires information. Also, an estimation of the communication intensity in the communication system at the determined moment in time is obtained. If the estimated communication intensity exceeds a certain threshold value, an appropriate period in time for the information providing device to send desired information to the subscriber equipment is calculated, based on the communication intensity in the communication system. Furthermore, a trigger signal is sent to the information providing device, requesting the information providing device at what moment in time to provide information to the subscriber equipment. A method in an information providing device is also disclosed.

摘要:
Adaptive redundancy is implemented (either switched on or off) for a voice over internet protocol (VoIP) packet connection by a basic two step approach. A first step of adaptive redundancy implementation involves monitoring relevant sources or indicators to determine when the need for redundancy (e.g., redundancy coding) may arise. A second step of adaptive redundancy implementation involves the triggering of redundancy implementation events when the monitored sources reach or obtain certain threshold value(s) (threshold). The first and second steps of redundancy implementation can be repeated as needed. Scenarios of adaptive redundancy implementation include both network-initiated implementations (e.g., implementations initiated by a radio access network (RAN)) and mobile-initiated implementations (e.g., implementations initiated by a wireless station).
