Problems solved by technology

[0005] In the prior art, it is planned to adopt a hybrid access mode for M2M applications and H2H applications, and use the same mechanism for M2M user equipment (UE, User Equipment, also called machine type communication equipment (MTC Device)) and H2H user equipment Therefore, there may be a large number of M2M applications in some access network elements or mobility management network elements, for example, a large number of access, resulting in the excessive load of the access network element or mobility management network element Occupied by M2M applications, which may greatly affect the normal operation of H2H applications

Embodiment 1

[0037] See figure 2 A load control method of Embodiment 1 of the present invention may include:

[0038] 210. Know the load status of the first network side network element.

[0039] The first network-side network element may be a mobility management network element or an access network network element, and of course, it may also be another type of network entity on the network side.

[0040] In an application scenario, if the device implementing the technical solution of this embodiment is located in the first network side network element, it can directly learn the load status of the first network side network element through monitoring; if the technology of this embodiment is implemented If the device of the solution is not located in the first network-side network element, it can learn the load status of the first network-side network element by receiving a message containing indication information of the load status of the first network-side network element.

[0041] It is unders...

Embodiment 2

[0055] In this embodiment, when the load ratio of the mobility management network element M1 exceeds a set threshold or is overloaded, the access network element A1 is responsible for the M2M user equipment and H2H user equipment under the mobility management network element M1. Access is controlled separately, and M2M user equipment is restricted from accessing the heavily loaded mobility management network element M1, and a specific description is given by taking the implementation of load control on the mobility management network element M1 as an example.

[0056] See image 3 A load control method of the second embodiment of the present invention may include:

[0057] 301. The access network element A1 learns the load control strategy of the mobility management network element M1 regarding the M2M user equipment.

[0058] In an application scenario, the mobility management network element M1 can send to the access network element A1 a message containing its load control policy i...

Embodiment 3

[0085] In this embodiment, when the load ratio of the mobility management network element M1 exceeds a set threshold or is overloaded, the access network element A1 provides services to the M2M user equipment and H2H user equipment under the mobility management network element M1. Perform differentiated control to restrict the M2M user equipment from performing services on the heavily loaded mobility management network element M1, and take the implementation of load control on the mobility management network element M1 as an example for specific description.

[0086] See Figure 4 , A load control method of the third embodiment of the present invention may include:

[0087] 401. The access network element A1 learns the load control strategy of the mobility management network element M1 regarding the M2M user equipment.

[0088] Among them, the specific implementation manner of obtaining the load control strategy of the M2M user equipment in step 401 can refer to step 301, which will ...

Abstract

The invention relates to a load control method, a device and a communication system. The load control method comprises acquiring the load condition of a network element of a first network side; and if the load proportion of the network element of the first network side exceeds a set threshold or the network element of the first network side overloads, limiting M2M user equipment to access or perform a service in the network element of the first network side according to a load control strategy of the network element of the first network side for the M2M user equipment. According to the method, the effect of an M2M application on an H2H application can be avoided or reduced relatively, and the method is beneficial for guaranteeing the H2H application to access and perform the service normally.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a load control method, a load control device and a communication system. Background technique [0002] Currently, the 3rd Generation Partnership Project (3GPP) has formulated a Long Term Evolution (LTE) plan. [0003] The wireless evolution network architecture of 3GPP non-roaming scenarios can be as follows figure 1 As shown, among them, the three functional entities of mobility management entity (MME, Mobility Management Entity), serving gateway (SGW, Serving Gateway), and packet data gateway (PGW, Packet Data Network Gateway) are core network equipment of the wireless evolution network . MME is mainly responsible for non-access stratum (NAS, Non Access stratum) signaling management, bearer management, user idle mode tracking and paging management functions; SGW is mainly responsible for local mobility anchors and mobility within the 3GPP system Anchor, and lawful int...
