Problems solved by technology

That is to say, these discarded or rejected call requests occupy a certain processing capacity of the switch in vain, but cannot be processed further, resulting in invalid occupation of the processing capacity of the switch

Embodiment 1

[0045] This embodiment proposes a switching network load control method based on routing query signaling, and controls the called routing query signaling based on the traffic load of the called switch and the type of the called user during the called routing query stage. When the called switch is overloaded, if at least one of the calling user and the called user is of high priority, it will be processed normally; if both the calling user and the called user are of low priority, it will not be processed and directly Return an error response and indicate overload to the called home HLR at the same time. After receiving the error response, the calling switch will not initiate the subsequent call connection process of this call. After receiving the overload error response, the called home HLR will reduce the signaling flow sent to the called switch. After the overload of the called switch is removed, the called switch handles it normally, and no longer indicates the overload to ...

Embodiment 2

[0060] This embodiment introduces the processing steps of the calling switch, such as figure 2 It is the implementation flowchart of Embodiment 2 of the present invention, including:

[0061] Step 201: the calling switch receives the call request of the calling user, and sends an SRI to the called home HLR.

[0062] Step 202: The calling switch receives the fed back SRI ACK message, and judges whether the SRI ACK message is a normal SRI ACK message, and if so, executes step 203; otherwise, executes step 204.

[0063] Step 203: The calling exchange connects the call to the called exchange according to the called roaming number in the normal SRI ACK message, and sends an IAM message. End the current process.

[0064] Step 204: The calling switch receives an abnormal SRI ACK message, where the error reason is overload, and does not send an IAM message.

Embodiment 3

[0066] This embodiment introduces the processing steps of the called home HLR, such as image 3 It is the implementation flowchart of Embodiment 3 of the present invention, including:

[0067] Step 301: After receiving the SRI, the called home HLR sends a PRN message to the switch where the called user resides (ie, the called switch) to request the roaming number of the called user.

[0068] Step 302: The called home HLR receives the PRN ACK message fed back by the called switch, and judges whether it is a normal PRNACK message, and if yes, executes step 303; otherwise, executes step 304.

[0069] Step 303: The called home HLR feeds back a normal SRIACK message to the calling switch, carrying the roaming number of the called user. End the current process.

[0070] Step 304: The called home HLR feeds back an abnormal SRIACK message to the calling switch, carrying an error cause of overload.

[0071] Step 305: Subsequently, when the called home HLR receives the SRI of the cal...

Abstract

The present invention proposes a method, system and device for realizing switching network load control, wherein the method includes: the called switch receives the provision roaming number (PRN) message sent by the called home HLR in the overload state, and judges the calling user and the called party. Whether the calling users are all low-priority, and if so, feed back an abnormal PRN ACK message to the called home HLR; the abnormal PRN ACK message is used to trigger the called home HLR to feed back an abnormal transmission route notification (SRI) ACK to the calling switch message, and the abnormal SRI ACK message is used to notify the calling switch to stop calling the called user. The invention can flexibly control the overload of the switch in the called route query stage earlier than the call connection stage, and avoid invalid occupation of the processing capacity of the switch. The called route query signaling can be controlled based on the called switch traffic load and user category.

Description

technical field [0001] The invention relates to the technical field of network load control, in particular to a method, system and device for realizing switching network load control. Background technique [0002] In the case of emergencies, the switching network often faces the impact of abnormal traffic load, which leads to the overload of the switch. In severe cases, the processing capacity may drop sharply, which affects the stable operation of the equipment and cannot guarantee normal communication services. Therefore, the control of abnormal traffic load has always been an important topic of emergency communication guarantee. Currently, the switching network load control mainly adopts the following two technologies: [0003] The first: switch overload control technology [0004] The basic principle of switch overload control is: to detect the traffic load of the switch, when the traffic load of the switch exceeds the overload control threshold per unit time, it is ju...
