Problems solved by technology

[0012] In the process of encapsulating data packets at the sending end through various protocol layers of HRPD, the encapsulated data packets processed by the HRPD protocol layers are purely upper-layer application data compared to the air interface of E-UTRAN. Since multiple headers and possible padding bits have been added to the encapsulated data packets processed by each protocol layer of HRPD, these pure overhead data that have nothing to do with useful data will be regarded as useful information in the air interface of E-UTRAN transmission, wasting precious resources of the air interface of E-UTRAN

Embodiment Construction

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0069] figure 1 It is a schematic diagram of the protocol layer of communication between AT and AN through E-UTRAN in the embodiment of the present invention. It should be noted that: the ATs in the embodiments of the present invention are all access terminals that do not reside in the AN of the HRPD network, and the AT resides in the access network under a different network; the AN in the embodiments of the present invention Both are access networks in the HRPD n...

Abstract

The embodiment of the invention relates to a data encapsulation method and a data encapsulation device. By the data encapsulation method and the data encapsulation device in the embodiment of the invention, the encapsulation processing of data packets by each protocol layer in a high rate packet data (HRPD) network at a sending end is changed, so that fragments during the encapsulation of the data packets can be reduced, the size of the packets is increased and bit filling is canceled; therefore, the overhead data of each protocol layer unrelated to useful data during data encapsulation are reduced, transmission resources between an access terminal in a heterogeneous network system and an access network in the HRPD network are saved, and transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data encapsulation method and device. Background technique [0002] High Rate Packet Data (HRPD for short) is the evolution version of CDMA2000-1X, the first stage of the development of Code Division Multiple Access (CDMA) 2000 system, and it is a technology specially optimized for packet data services . [0003] In a scenario where the HRPD network communicates with a different network system, the different network system is, for example, a Long Term Evolution (LTE for short) network. The access terminal (AT) in the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN for short) residing in the LTE network and the access network in the HRPD network (Access Network, referred to as AN) communication as an example, when the sender (AT or AN) wants to send a message to the receiver (AN or AT), first the sender nee...
