Abstract: Various solutions for short message service re-transmission with respect to user equipment and network apparatus in mobile communications are described. An apparatus may transmit a control plane-data (CP-DATA) message for initiating mobile originated short message service (MO SMS). The apparatus may determine a first timer value for first transmission of the CP-DATA message. The apparatus may further re-transmit the CP-DATA message in response to expiration of the first timer value. The apparatus may further determine a second timer value for re-transmission of the CP-DATA message. The second timer value may be smaller than the first timer value.

Abstract: A method is disclosed for providing information related to an Internet Protocol (IP) Multi-Media (IM) Subsystem (IMS) to a mobile terminal. The method includes storing the information into a memory that is readable by the mobile terminal, and reading the stored information from the memory. The memory may be at least one of a USIM, an EEPROM or a RAM. In one embodiment the information is stored during a PDP context activation procedure. A wireless communications system that operates in accordance with the method is also disclosed.

Abstract: A start-up operation of devices using smart cards, and more precisely to the initialization procedure of smart cards is used in mobile stations during the start-up of the mobile station. The invention is based on the realization that information of the REPLACE-type of messages can be dealt with more quickly if the information of the type of the message already occurring once in the TP-PID byte of the record is added to the first byte of the record, the STATUS byte, whereby messages of the REPLACE type can be sought by the SEEK command of the SIM card. When this procedure is used in the start-up, there is no need to read all the records of the file containing the SMS messages on the SIM card in order to find the REPLACE-type of messages.
