METHODS AND DEVICES FOR MESSAGE ATTACHMENT TRANSMISSION

摘要

Methods and devices for transmitting message attachments from a messaging server to a mobile device. The mobile device identifies if any of the attachments are of a first type and requests transmission, from the messaging server, of the identified attachments of the first type, if any. The device determines the remaining transmission capacity by subtracting the collective size of the message body received and the identified attachments of the first type, if any, from the initial data limit. Based on the remaining transmission capacity, the device determines that at least one of the one or more attachments, other than the identified attachments, has a size smaller than the remaining transmission capacity, and based on that determination, requests transmission of said at least one of the one or more attachments from the messaging server to the mobile device.

主权项

1. A method of transmitting message data to a mobile device from a messaging server over a data connection, wherein a message includes one or more attachments, an initial data limit is associated with message transmissions to the mobile device, and wherein the mobile device receives at least part of the message and a list of the attachments, the method comprising:
identifying any of the one or more attachments that are of a first type of attachment; requesting transmission, from the messaging server to the mobile device, of the identified attachments of the first type, if any; determining the remaining transmission capacity by subtracting the collective size of the at least part of the message and the identified attachments of the first type, if any, from the initial data limit; and based on the remaining transmission capacity,
determining that at least one of the one or more attachments, other than the identified attachments, has a size smaller than the remaining transmission capacity, and based on that determination, requesting transmission of said at least one of the one or more attachments from the messaging server to the mobile device.
