Method For Reduced-Overhead Short Message Transmission

For applications with very small data activities, connection of a UE to a wireless network for sending or receiving such small data traffic increments via conventional connection set-up processes is quite inefficient in terms of spectral resource utilization. The invention provides a new connectionless methodology for transmission of such small data increments between a UE and a serving eNB. In particular, the invention methodology contemplates identifying a set of preamble sequences among the pool of preamble sequences provided for access requests from a UE to an eNB via the Random Access Channel as corresponding to a request from the UE for access to transmit an increment of data smaller than a predetermined threshold data size. When a UE has data traffic to transmit of a size smaller than the predetermined threshold size, it selects one of the preamble sequences in the identified set and sends an access request, using the selected preamble sequence, to a serving eNB via the Random Access Channel. Upon receipt of the access request from the UE, the eNB determines an appropriate RF resource for the data increment sought to be transmitted by the UE, based on the use of the selected preamble sequence sent by the UE, and schedules an uplink connection for the transmission of that data increment by the UE.

Method for implementing dynamic card selection and memory of mobile phone supporting multiple cards

The invention provides a method for implementing dynamic card selection and memory of a mobile phone supporting multiple cards. The method comprises the following steps of: inserting multiple subscriber identity module (SIM) cards into the mobile phone by a user; during first use, trigging a new event to prompt the user which SIM card is used; judging whether the new event is triggered for the SIM card and whether operation records exist; if so, continuously judging whether the new event is associated with one of the multiple SIM cards; if not associated, popping up an SIM card selection prompt dialog box, and if associated, further executing the information associated with the SIM card and recommending the SIM card to operate with default highlight; and if the result of judging the new event is denied, automatically memorizing the SIM card selected by the user last time through the mobile phone and recommending the SIM card with highlight, wherein the highlight SIM card can be directly used for operation. The method solves the technical problems of complex steps, flexibility insufficiency and the like, simplifies the setting and operation steps of the mobile phone, and is convenient to meet the requirement of the user.

The invention discloses a method for performing calibration time delay error testing on a time delay calibration switch of an intelligent substation. The method comprises the following steps: performing special processing on a transmitting port SV (Sampling Value) message; after the time delay calibration switch receives the SV message, calculating a time delay value from the entrance of the message into a receiving port to the transmission of the message from another port, and filling the time delay value into a reserved field of the SV message; receiving and filtering a specific SV message by the receiving port, and locking a first bit time scale of a received first frame message; calculating a measured time delay value; solving the received SV message, and extracting a switch time delay value calibrated in the reserved field of the SV message; and calculating the difference between the measured time delay value and the calibrated time delay value. The calibrated SV time delay error of the switch can be measured conveniently, so that the performance of the switch can be evaluated, and the reliability of interpolation synchronization on the SV message received by a relay protection device can be ensured. Moreover, a parameter setting process is simple; the requirement on the knowledge level of testing personnel is lowered; and the testing efficiency is high.
