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

[0105] This embodiment is used to illustrate the implementation of AD registering with the network and enabling the DSC function. In this process, the DSC and the core network are respectively as follows:

[0106] 1. On AD (DSC):

[0107] After establishing a connection with the core network, send a service authorization request message to the device that manages the DSC on the core network, and the service authorization request message carries the identification information and identity verification information of the DSC;

[0108] Receive a service authorization request message sent by the device managing the DSC, where the service authorization request message carries the function parameter configuration information.

[0109] 2. On the core network side:

[0110] The communication request message sent by the DSC is a service authorization request message sent by the DSC after establishing a connection with the core network, and the service authorization request message carri...

Embodiment 2

[0125] This embodiment is used to illustrate the implementation of establishing the Me1 interface between the DSC and the core network NSC. In this process, the DSC and the core network are respectively as follows:

[0126] 1. On the DSC:

[0127] When the function parameter configuration information includes: core network NSC identification or core network NSC address information;

[0128] Then according to the function parameter configuration information, it is determined that the communication requirement on the DSC is to establish a Me1 interface communication connection;

[0129] The communication request message sent to the NSC is a Me1 interface establishment request message;

[0130] It further includes: after receiving the Me1 interface establishment complete message returned by the NSC, saving the status information of the successful establishment of the Me1 interface.

[0131] 2. On the core network side:

[0132] The communication request message sent by the DSC...

Embodiment 3

[0141] This embodiment is used to illustrate the implementation of DSC sending system broadcast information through the air interface, which can carry network information, cluster information, and service information. In this process, DSC and EP are as follows:

[0142] 1. On the DSC:

[0143] When the function parameter configuration information includes: DSC equipment identification, network identification, cluster identification, service identification;

[0144] Then, according to the functional parameter configuration information, it is determined that the communication requirement on the DSC is to broadcast system information in the cluster that needs to be known by the devices in the cluster;

[0145] The communication request message sent to the corresponding device is a system broadcast message sent through the air interface, and the system broadcast message includes one or a combination of the following information: DSC device identifier, network identifier, cluster i...

Abstract

Disclosed are a method and device for communications, comprising: on a distributed service center, determining function parameter configuration information of the distributed service center, where the function parameter configuration information comprises: a distributed service center device identification, a network identification, a cluster identification, cluster information, a service identification, network service center identification or address information of a core network; determining communication needs on the distributed service center on the basis of the function parameter configuration information, and transmitting a communication request message to a corresponding device. When the communication request message transmitted by the distributed service center is received by a network service center device of the core network, the device responds on the basis of the communication request message. When a system broadcast message transmitted via an air interface is received by an end point node, same updates cluster state information on the basis of the system broadcast message. Employment of the present invention not only reduces the load that an access device incurs on the core network in storage and signal processing, but also localizes a control function, thus greatly reducing delay caused by a control plane signaling process.

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...
