Problems solved by technology

[0020] When the physical location between devices is far away, that is, when the RTT (Round Trip Time, packet round-trip time) is large, the HIP connection establishment delay is large, which affects user experience
[0021] When the device IP address changes, all connected devices need to be notified, and the delay and overhead are large. For example, Figure 4 shown

Embodiment 1

[0084] Figure 9 is based on Figure 8 The connection relationship maintenance system composed of SN nodes shown in the figure stores the binding relationship between the HIP equipment HIT and the HAP, and the HIP equipment UE1 and UE2 at the two ends of the communication are connected to different HAPs, including the following steps:

[0085] Step 901, UE1 establishes a HIP connection with HAP1, and UE2 establishes a HIP connection with HAP2;

[0086] Taking UE as an example, UE1 obtains the address of HAP1 with a smaller RTT by querying a statically configured server, DHCPv6 (Dynamic Host Configuration Protocol for IPv6) or DNS, and UE1 establishes a HIP connection with HAP1. HAP1 stores the correspondence between the HIT of UE1 and the IP address of UE1. HAP1 stores its binding relationship with the HIT of UE1 in the responsible SN node of UE1.

[0087]Step 902, UE1 uses its HIP connection with HAP1 to send the data packet it wants to send to UE2 to HAP1;

[0088] UE1 n...

Embodiment 2

[0110] Figure 10 is an embodiment in which the HIP device of the present invention closes the HIP connection between it and the HAP, wherein, using Figure 8 The connection relationship maintenance system composed of the SN nodes shown is used to store the binding relationship between the HIP device and the HAP. The HIP devices UE1 and UE2 at the two ends of the communication are connected to different HAPs, including the following steps:

[0111] Step 1001 UE1 establishes a HIP connection with HAP1, and UE2 establishes a HIP connection with HAP2; taking UE as an example, UE1 obtains the address of HAP1 with a smaller RTT by querying a statically configured server, DHCPv6 (Dynamic Host Configuration Protocol for IPv6) or DNS, etc., UE1 Establish a HIP connection with HAP1. HAP1 stores the correspondence between the HIT of UE1 and the IP address of UE1. HAP1 stores its binding relationship with the HIT of UE1 in the responsible SN node of UE1.

[0112] Step 1002, UE1 uses i...

Embodiment 3

[0120] like Figure 11 Schematic diagram of IP address change for HIP devices, based on Figure 11 In the case of , the process of changing the IP address is as follows: Figure 12 shown, including the following steps:

[0121] Step 1201, UE1 obtains the HAP address by querying a statically configured server, DHCPv6 (Dynamic Host Configuration Protocol for IPv6), or DNS, etc., UE1 establishes a HIP connection with HAP1, and HAP1 stores the correspondence between UE1's HIT and the IP address;

[0122] Step 1202, the IP address of UE1 changes;

[0123] Step 1203, UE1 sends HIPUpdate to its associated HAP1 to notify the change of IP address. HAP1 records the change of UE1's IP address;

[0124] Step 1204, other devices communicating with UE1 such as UE2 send data to UE1;

[0125] Step 1205, HAP1 finds that the IP address notified by UE1 of the IP address change is the only address sent to UE1, then it can cache the data sent to UE1;

[0126]Step 1206, HAP1 sends an Update c...

Abstract

Disclosed is a method and system of communication based on HIP, and HIP device and HIP access point, wherein the method is based on the Host Identity Protocol (HIP) device and the HIP access point (HAP). The method comprises: the HIP device establishes connection with HAP; source HIP device sends data package to source HAP via HIP connection; and the source HAP receives the data package and forwarding the data package based on HIP connection relationship or IP address of the destination device. The present invention can improve user experience by reducing HIP connection required and time delay by the HIP device.

Description

technical field [0001] The present invention relates to the field of telecommunications, in particular to a HIP-based communication method, system, and set of equipment (including HIP equipment and HIP equipment access nodes). Background technique [0002] At present, in the Internet, the IP address serves not only as an addressing function, but also as an identification of a communication device node. This dual function determines that when the IP address changes, not only the route changes, but also the identification of the host of the communication device changes, which affects the continuity of the business. In order to solve this problem, IETF introduces the HIP (HostIdentityProtocol, host identification protocol, host identification protocol defined by the IETF HIP working group) protocol, which solves the binding of device identification and address. HIP requires any device to have a globally unique host identification code HI (HostIdentifier). The host identificat...
