Abstract

The invention discloses a method for processing a PUSH notification, including: placing non-compressible fields into the Push notification and placing into the PUSH notification a field signifying message type and a field of internal ID after the fields are compressed; determining whether the PUSH notification may be carried in one short message; if yes, having the PUSH notification carried in one short message; otherwise, having the PUSH notification carried in two short messages; determining whether there are any unoccupied bytes in the short message; if yes, determining whether to place the initiator From field into the PUSH notification according to the number of the unoccupied bytes in the short message, and determining whether to compress Subject field and place the Subject field into the PUSH notification; otherwise, terminating the processing flow of the PUSH notification. The present invention may have the PUSH notifications carried in two short messages at most.

Claims

1. A method for processing a PUSH notification in multimedia message service, comprising:

placing non-compressible fields of the PUSH notification into the PUSH notification, compressing a Type field signifying message type and a Transaction identification (TID) field of Internal ID, and placing the compressed Type field and the compressed TID field into the PUSH notification;

determining whether the PUSH notification can be carried in one short message;

if the PUSH notification can be carried in one short message, having the PUSH notification carried in one short message;

if the PUSH notification cannot be carried in one short message, having the PUSH notification carried in two short messages;

determining whether there are unoccupied bytes in the short message;

if there are unoccupied bytes in the short message, determining whether placing a From field signifying an initiator of the message into the PUSH notification according to number of the unoccupied bytes in the short message, and determining whether compressing a Subject field as well as placing the Subject field into the PUSH notification according to number of the unoccupied bytes in the short message;

if the From field has already been put into the short message, whereas there are no enough bytes in the short message to hold the Subject field, discarding the Subject field;

if there are unoccupied bytes in the short message, but the From field cannot be hold in the short message, discarding the From field and the Subject field that are not placed into the PUSH notification.

2. The method according to claim 1, wherein, the non-compressible fields of the PUSH notification placed into the PUSH notification comprise:

10 fields except the Type field signifying the message type, the TID field signifying the internal ID, the From field signifying the initiator of the message and the Subject field signifying a subject of the message.

3. The method according to claim 1, wherein, the process of compressing the Type field signifying the message type comprises:

expressing the Type field signifying the message type with binary codes that takes up 1 byte.

4. The method according to claim 1, wherein, the process of compressing the TID field of the internal ID comprises:

discarding a central ID of the multimedia message service in the internal ID, and expressing time part in seconds;

discarding the central ID in the field of the internal ID, expressing the time part with seconds and converting the field of the internal ID into codes of 64 based number system.

5. The method according to claim 1, wherein, the process of determining whether the PUSH notification can be carried in one short message comprises:

determining whether length of the PUSH notification is shorter than 140 bytes;

if length of the PUSH notification is shorter than 140 bytes, the PUSH notification can be carried in one short message;

otherwise, the PUSH notification cannot be carried in one short message.

6. The method according to claim 1, wherein, the processes of determining whether to place the initiator From field into the PUSH notification and whether to compress the Subject field and place the Subject field into the PUSH notification comprises:

determining whether the unoccupied bytes in the short message are enough to hold the From field, if the unoccupied bytes in the short message are not enough to hold the From field, discarding the From field and the Subject field, and terminating the processes of the PUSH notification;

otherwise placing the From field into the Push notification;

determining whether the Subject field may adopt a character set or a coding mode to make a coding length of the Subject field shorter;

if the Subject field may adopt the character set or a coding mode to make the coding length of the Subject field shorter, adopting the character set or the coding mode of shorter coding length to express the Subject field;

otherwise, adopting originally used character set or coding mode;

determining whether the unoccupied bytes in the short message holding the From field are enough to hold the character set or the coding mode of the Subject field and codes corresponding to at least one character in a character string code of the Subject field;

if the unoccupied bytes in the short message holding the From field are enough to hold the character set or the coding mode of the Subject field and the codes corresponding to at least one character in the character string code of the Subject field, placing the character set or the coding mode into the PUSH notification, and placing the codes corresponding to an individual character in the character string code into the PUSH notification in sequence according to the unoccupied bytes in the short message;

otherwise, discarding the Subject field and terminating the processes of the PUSH notification.

7. The method according to claim 6, wherein, the process of placing the codes corresponding to the individual characters in the part of the character string codes into the PUSH notification in sequence comprises:

determining bytes occupied by the codes to express one displayable character in the existing coding mode;

calculating the number m of the displayable characters that the short message may hold according to the unoccupied bytes of the short message holding the character set coding mode and the coding bytes determined according to the existing coding mode;

placing the codes corresponding to the characters from the first one to m of the character string coding part in the Subject field into the PUSH notification in sequence.
