Problems solved by technology

[0003] For multimedia applications such as voice, IP technology can reduce costs, but the voice is transmitted in the traditional IP format. (UserDatagram Protocol, referred to as UDP), compared with the voice payload, RTP / UDP / IP packets have a large header overhead, which will bring a lot of waste to wireless air interface resources

Embodiment Construction

[0029] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] refer to figure 1 , illustrating the linked list encoding method according to the embodiment of the present invention. like figure 1 As shown, the linked list encoding method includes the following steps: S102, comparing the reference linked list and the current linked list; S104, setting the insertion / deletion bit mask, selecting the encoding method according to the comparison result, and using the selected encoding method to encode the current linked list or the reference linked list The insertion or deletion bitmask is encoded.

[0031] Wherein, the process of comparing the reference linked list and the current linked list includes the following steps: comparing the i-th element of the current linked list with the k-th element of the reference linked list; if the i-th element of the current linked list is identical to ...

Abstract

The present invention discloses a method and a system for link list encoding. The link list coding method includes steps below: S102. A reference link list is compared with a current link list; S104. It is necessary to add / delete bit mask code, select an encoding method according to the comparison above and utilizes the selected encoding method to encode added / deleted bit mask code in the currentor reference link list. The present invention greatly reduces quantity of element comparison between the current link list and the reference link list, improving encoding efficiency and enhances module reusability in a proposal of deletion at first and then addition by making functions of calculating added / deleted bit mask code, etc. independent.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to a linked list encoding method and system. Background technique [0002] The third generation mobile communication (3 rd Generation (3G for short) technology has become one of the most concerned communication technologies in the world. As a new communication technology, 3G not only supports traditional circuit switching, but also supports packet switching. However, some technologies after 3G (for example, B3G (Beyond 3G) and WiMax, etc.) have turned to packet switching, that is, technologies that mainly support Internet Protocol (Internet Protocol, IP for short). [0003] For multimedia applications such as voice, IP technology can reduce costs, but the voice is transmitted in the traditional IP format. (UserDatagram Protocol, referred to as UDP), compared with the voice payload, the RTP / UDP / IP message has a large header overhead, which will cause a great waste...
