Short message service (SMS) message segmentation

摘要

Disclosed herein is a technique for preventing words from spanning across message blocks of a short message service (SMS) message. An SMS message is generated at a source wireless device, and an SMS manager, executing on the source wireless device, determines whether any words in the SMS message span across two or more message blocks of the SMS message. When so determined, the SMS manager attempts to shift characters of the SMS message across the message blocks to eliminate any word spanning. When the attempt to shift the characters between message blocks requires at least one additional message block to transmit the complete SMS message, the SMS manager gathers information about the destination wireless device to determine whether it is necessary to carry out the aforementioned shifting prior to sending the message blocks. The SMS manager then transmits the message blocks either unmodified or modified (i.e., shifted).

1. A method for conditionally shifting a word that spans across two message blocks of a short message service (SMS) message that each share a fixed character limit, the method comprising:
at a source wireless device:
identifying that the word spans across the two message blocks, wherein the two message blocks include a first message block and second message block;determining that shifting the word from the first message block to the second message block would cause the fixed character limit of the second message block to be exceeded and require an additional message block to transmit the SMS message;in response to determining, analyzing information about a destination wireless device that will receive the SMS to determine whether shifting the word should be carried out;when shifting the word should not be carried out:
sending the two message blocks to the destination wireless device; andwhen shifting the word should be carried out:
shifting the word from the first message block to the second message block to establish the additional message block, andsending the two message blocks and the additional message block to the destination wireless device.
