Problems solved by technology

[0004] First of all, since the number of machine-type terminals in the future will far exceed the number of existing terminals (it is predicted that it may reach 50 billion to 100 billion levels), if a complete context is to be established for each machine-type terminal on the core network, it will cause the core network to store overwhelmed
In addition, the connection management function of existing terminals also involves the core network, which means that every time a terminal enters the connection state, a large amount of signaling to the core network will be generated, and a large number of machine-type terminals connected to the network can easily cause signaling storms

Embodiment 1

[0102] This embodiment is used to illustrate the implementation of the terminal EP Attach (Attach) network. In this process, the DSC, EP, and core network are respectively as follows:

[0103] 1. On the DSC:

[0104] When the EP accesses the network, the communication request message received on the DSC is the attachment request message of the EP, and the message also carries the identity verification information of the EP;

[0105] The communication processing message sent to the core network is the identity verification request message of the EP, and the message also carries the identity verification information of the EP;

[0106] After the core network returns the identity verification pass response message, the communication response message returned to the EP is an attach response message, and a temporary identifier is allocated to the EP.

[0107] During implementation, when the core network returns the identity verification pass response message and also returns the cor...

Embodiment 2

[0153] This embodiment is used to illustrate the implementation of terminal EP triggering detachment (Detach deregistration). In this process, DSC, EP, and core network are respectively as follows:

[0154] 1. On the DSC:

[0155] The communication request message received on the DSC is the detachment request message of the EP, and the message also carries the temporary identifier of the EP;

[0156] The communication processing message of the EP sent to the core network is a status update message of the EP;

[0157] The communication response message returned to the EP is a detachment response message.

[0158] 2. On the EP:

[0159] The communication request message sent to the DSC is a detachment request message, and the message also carries the temporary identifier of the EP;

[0160] The communication response message returned by the receiving DSC is a detachment response message.

[0161] 3. On the core network side:

[0162] Receive the EP status update message sen...

Embodiment 3

[0172] This embodiment is used to illustrate the implementation of the periodic status update triggered by the terminal EP. In this process, the DSC, EP, and core network are as follows:

[0173] 1. On the DSC:

[0174] The communication request message of the EP received on the DSC is a status update request message sent periodically by the EP, and the message also carries the temporary identification of the EP;

[0175] The communication processing message sent to the core network is a terminal status update request message;

[0176] The communication response message returned to the EP is a status update response message.

[0177] In implementation, it may further include:

[0178] According to the temporary identifier of the EP, the timer for updating the state information of the EP is reset.

[0179] 2. On the EP:

[0180] The communication request message sent to the DSC is a status update request message sent periodically, and the message also carries the temporary ...

Abstract

The invention discloses a communication method and equipment, comprising: receiving a communication request message of an end node at a distributed service center, the communication request message carrying an identifier of the end node; sending the communication request message of the end node to a core network Processing a message, the communication processing message carries the identifier of the end node; after receiving the communication processing message sent by the distributed service center to the core network, returning a communication response message to the end node. By adopting the present invention, not only can greatly reduce the burden of the access equipment on the storage and signaling processing of the core network. Moreover, the localization of the control function will greatly shorten the delay caused by the signaling process of the control plane.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication method and equipment for machine equipment. Background technique [0002] figure 1 It is a schematic diagram of the existing cellular network architecture. As shown in the figure, in the existing cellular system, the terminal determines the serving base station according to the strength of the downlink pilot signal, and the serving base station is responsible for providing data transmission services for the access terminal. The serving base station forwards the uplink data received from the terminal to the core network. The core network is responsible for verifying the identity of the terminal, saving the context information of the terminal, and providing connection services to the external network for the access terminal. [0003] In the prior art, the terminal completes the registration process with the network through an attach (Attach) process...
