Abstract: There are provided measures for enhancement of packet based voice call service over satellite link. Such measures exemplarily include receiving, from a communication endpoint, a message indicative of at least one voice data packet to be uploaded via a satellite link, determining a first number of voice data packets based on a second number of voice data packets predicted to accumulate until receipt of a first grant message at said communication endpoint, and transmitting, towards said communication endpoint, said first grant message, said first grant message being indicative of an upload scheduling grant for said first number of voice data packets.

Abstract: In a cell where messages having a message type are sent without knowledge of radio frequency conditions for individual ones of user equipment within the cell, measured radio frequency conditions are accessed of multiple user equipment within the cell. Based on the measured radio frequency conditions, a minimum control channel coding rate is determined for a control channel for messages having the message type. Subsequent to a determination of the minimum control channel coding rate, transmission is caused toward all user equipment in the cell of the messages having the message type using the determined minimum control channel coding rate for the control channel. Methods, apparatus, computer programs, and program products are disclosed. The methods may be performed by a base station, self-organizing network server, or other apparatus.

Abstract: Performing power control by determining a maximum required signal-to-interference plus noise ratio for a nominal packet size of a received data signal, wherein the maximum required signal-to-interference plus noise ratio corresponds to a quantity of physical resource blocks used for the nominal packet size of the data signal. A received signal-to-interference plus noise ratio of the received data signal is compared with the maximum required signal-to-interference plus noise ratio. In response to the received signal-to-interference plus noise ratio exceeding the maximum required signal-to-interference plus noise ratio, power control is performed for the data signal to reduce the received signal-to-interference plus noise ratio.

Abstract: A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the system determines a target combination of RC3 and RC4 calls based upon the current average power per link measurements for RC3 and RC4 calls, and based upon the power limitations of the system. The technique strives to maximize the capacity of the system while maintaining operation below the overall power limit.

Abstract: A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the percentage of RC4 calls increases while the percentage of RC3 calls decreases. The technique strives to minimize overall power consumption in the system for all call load conditions, by maximizing the number of RC3 calls at any given time while keeping Walsh code resources available for both new calls and hand-in traffic.

Abstract: A method for adaptive power control in a mobile communication system (100) determines (120) whether an RF loading factor (110) is greater than a threshold value. If the RF loading factor is above the threshold value, the method reduces call quality (140). Next, a determination is made whether the RF loading factor is below a second threshold value (150). If the RF loading factor is below the second threshold value, the call quality of the mobile communication system is increased (160).

Abstract: This method (110) adaptively sends control messages and a predetermined number of fast repeats of the control messages on the traffic channel of a mobile communication system. For a control message which has already been lost (118), the system sends the control message again with a first number of fast repeats (130) if the traffic channel is operating at a full rate; and the system sends the control message with a second number of fast repeats if the traffic channel is operating at a subrate. The number of fast repeats is selectable. If the control message has not been previously sent and the traffic channel is operating at a subrate (124), the system will send the control message with a third number of fast repeats (128).

Abstract: A mobile unit 40 which is in a soft handoff condition 50 with a base station (32) has the power transmitted by the base station (32) on the mobile link (52) controlled. The base station (32) determines (70) when a frame erasure count reaches a particular level N. The base station then places this link in a clamped state (72) at minimum power. When the base station determines that M consecutive good frames have been received (92), the base station restores the link (52) to a normal state (94). A recovery arrangement (100, 110 and 120) prevents clamping by all base stations (32-34) and loss of the link.
