Embodiment 1

[0092] TCP / IP protocol (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Internet Protocol), is the most basic communication protocol of the Internet. Such as figure 1 As shown, the TCP / IP protocol is mainly composed of four layers, which are application layer, transport layer, network layer and network interface layer from top to bottom. due to figure 1 In the shown TCP / IP protocol architecture, the IP address at the network layer assumes the dual roles of communication device identity and location identification, and this dual role limits the mobility, security, and multi-platform accessibility of communication devices. In view of the above, those skilled in the art have proposed such as figure 1 The TCP / IP protocol of the shown ID ((identification, identity mark) and Locator (location mark). Wherein, the TCP / IP protocol includes five layers, which are respectively application layer, transport layer, ID layer from top to bottom layer...

Embodiment 2

[0117] In practical applications, the destination communication device can adopt the TCP / IP communication protocol with ID / Locator separation architecture, or the TCP / IP communication protocol with ID / Locator non-separation architecture (that is, the traditional TCP / IP four-layer communication protocol) , and for the destination communication device using the ID / Locator separation architecture and the destination communication device without the ID / Locator separation architecture, the source communication device obtains the destination ID and the destination Locator in different ways, so the source communication device before encapsulating the data packet , it is necessary to first determine the TCP / IP communication protocol architecture adopted by the destination communication device.

[0118] In the embodiment of the present invention, such as Figure 6 As shown, the following methods can be used to obtain the communication protocol architecture of the destination communicat...

Embodiment 3

[0143] If using any one of the three implementations provided in Embodiment 2, the source communication device determines that the destination communication device adopts the TCP / IP communication protocol of the ID / Locator separation architecture; The data packets to be sent are encapsulated at the application layer and the transport layer, and then steps S31 and S32 in Embodiment 1 are used to determine whether the current service needs mobility support;

[0144] 1. If the source communication device determines the current service and needs mobility support, its application scenarios can be found in Figure 7 , Step S33 in Embodiment 1: the source communication device acquires the source ID and source Locator of the source communication device, and the destination ID and destination Locator of the destination communication device, as follows:

[0145] The source communication device selects two IP addresses from a preset address pool as the source ID and source Locator respec...

Abstract

The invention discloses a service data packet encapsulating method and device. The method at least comprises the steps that a source communication device acquires the mobility support parameter of a current service, wherein the mobility support parameter is used for indicating whether a corresponding service needs mobility support, and the source communication device at least comprises an ID identity layer and a Locator location layer; the source communication device determines whether the current service needs mobility support according to the mobility support parameter of the current service; when the source communication device determines that the current service does not need mobility support, the source Locator of the source communications device and the destination Locator of a destination communications device are acquired; and the source Locator and the destination Locator are used to encapsulate the Locator layer of a data packet to be sent by the current service. According tothe service data packet encapsulating method and device, network overhead can be saved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for encapsulating service data packets. Background technique [0002] TCP / IP protocol (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Internet Protocol), is the most basic communication protocol of the Internet. Such as figure 1 As shown, the TCP / IP protocol is mainly composed of four layers, which are application layer, transport layer, network layer and network interface layer from top to bottom. due to figure 1 In the shown TCP / IP protocol architecture, the IP address at the network layer assumes the dual roles of communication device identity and location identification, and this dual role limits the mobility, security, and multi-platform accessibility of communication devices. In view of the above, those skilled in the art have proposed such as figure 1 The TCP / IP protocol of the shown ID ((identif...
