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] Referring to FIG. 1 , the linked list encoding method according to the embodiment of the present invention is illustrated. As shown in Figure 1, this linked list coding method comprises the following steps: S102, compare reference linked list and current linked list; Or encode with reference to the insertion or deletion bitmask of the linked list.

[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 the k-th element of the reference linked list , then compare the i+1th element of the current linked list with the k+1th element of the reference linked list, otherwise compare the i+1th e...

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 current or 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 ...
