Abstract: Implementing a multimedia calling line identification presentation service. A multimedia resource notification module obtains a storage address of a multimedia resource that is stored by a resource storage entity and that is subscribed to by a calling terminal, and sends the storage address of the multimedia resource to a resource playing entity. A service management module establishes a media channel between the resource playing entity and the called terminal for playing the multimedia resource. Establishing the media channel includes sending multimedia session information to the called terminal, the multimedia session information having been received by the service management module from the resource playing entity. Establishing the media channel also includes sending negotiated multimedia session information to the resource playing entity, the negotiated multimedia session information having been received by the service management module from the called terminal.

Abstract: From one perspective, an apparatus receives a request for a calling terminal device to initiate a session with a called terminal device. Based on the request, the apparatus obtains a storage address of the multimedia resource, and sends the address to the called terminal device. Based on sending the address the apparatus receives, from the called terminal device, a message indicating the called terminal device is playing the multimedia resource, and a message indicating that the called terminal device is off-hook. The called terminal device stops playing the multimedia resource when off-hook. From another perspective, a terminal device receives a storage address of a multimedia resource from a service management entity. The terminal device downloads the multimedia resource from a resource storage entity, and plays the multimedia resource as part of ringing, and before detecting that it is off-hook. The terminal device ceases playback after detecting it is off-hook.

Abstract: Automatic retransmission in communications systems. In one embodiment, a portion of data is identified to be retransmitted based on feedback information indicating a negative acknowledgement (NACK) during a cyclic redundancy check (CRC) on a previous transmission of the portion of data. A retransmission mode is selected for the portion of data, from at least a first mode that retransmits the portion of data on at least a first transmitter antenna while transmitting new data on at least a second transmitter antenna, based on first desired transmission characteristics; and a second mode that retransmits the portion of data simultaneously on at least the first and second transmitter antennas, based on second desired transmission characteristics.
