Embodiment 1

[0060] See image 3 As shown, the load control method in this embodiment includes the following steps:

[0061] Step 301: the mobile management entity (MME) device sends a service message to the enhanced mobile switching center (eMSC) device through the Sv interface;

[0062] Step 302: The enhanced mobile switching center device receives the service message sent by the enhanced mobile switching center device;

[0063] Step 303: The enhanced mobile switching center device inserts its own current load message into the processing message obtained by processing the service message;

[0064] Step 304: The enhanced mobile switching center device feeds back the processing message to the mobility management entity device through the Sv interface;

[0065] Step 305: the mobility management entity device receives the processing message fed back by the enhanced mobile switching center device;

[0066] Step 306: The mobility management entity device obtains the load information of the ...

Embodiment 2

[0081] See Figure 4As shown, the present embodiment provides a communication system, which includes an enhanced mobile switching center device 2 and a mobility management entity device 1; the mobile management entity device 1 sends a service message to the enhanced mobile switching center device 2 through the Sv interface; the enhanced mobile switching The central device 2 receives the service message sent by the enhanced mobile switching center device, inserts its own current load message into the processing message obtained by processing the service message, and feeds it back to the mobility management entity device 1 through the Sv interface; the mobility management entity device 1 receives The processing message fed back by the enhanced mobile switching center device 2 obtains the load information of the enhanced mobile switching center device 2 from the processing message, and decides to subsequently initiate services to the enhanced mobile switching center device 2 accor...

Embodiment 3

[0103] In order to better understand the present invention, the present invention will be further illustrated below in combination with several specific application scenarios as examples.

[0104] In this embodiment, the load message includes the occupied user ratio POS, that is, the occupied user ratio POS represents the current load situation of the enhanced mobile switching center device. Protocol 29.280 defines the messages and parameters of the Sv port. This embodiment newly defines the parameter Percent of Occupied Subscribers (the ratio of occupied users), referred to as POS, as shown in Table 1. Its value is the current Srvcc access user The ratio of the number to the total number of Srvcc service users that can be handled by the eMSC is 0-100, respectively representing (0%-100%).

Abstract

The invention discloses a load reporting and control method, an eMSC apparatus, a MME apparatus and a communication system. The MME apparatus sends a service message to the eMSC apparatus through a Sv interface. The eMSC apparatus inserts a current load message of the eMSC apparatus itself into a processing message used for processing the service message sent by the eMSC apparatus. The eMSC apparatus feeds the processing message back to the MME apparatus through the Sv interface. The MME apparatus acquires the current load message of the eMSC apparatus from the processing message and decides to subsequently initiate a service to the eMSC apparatus according to the load message. In the invention, after the eMSC can insert the current load message of the eMSC apparatus itself into the processing message used for processing the service message sent by the MME apparatus, the message can be fed back to the MME apparatus so that the MME apparatus dynamically knows a load condition of an eMSC apparatus side and then dynamically decides how to initiate the service to the eMSC apparatus subsequently. A condition that a service storm on the Sv interface between the eMSC apparatus and the MME apparatus is generated so that the load is continuously increased or a service success rate is decreased is avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to a load reporting and control method, an eMSC (enhanced Mobile Switch Center, enhanced mobile switching center) device, an MME (Mobile Management Entity, mobility management entity) device and a communication system. Background technique [0002] See figure 1 As shown, the Sv interface is currently the interface between MME (Mobile Management Entity, mobility management entity) and eMSC (enhanced mobile switch center, enhanced mobile switching center) during the handover process of Srvcc (Signal Radio Voice Call Continutity, single channel continuous service) , which is mainly responsible for the signaling interaction between MME and eMSC during the Srvcc process. The interface communication is based on the GTPC (Tunneling Protocol for Control plane) transmission protocol on UDP (User Datagram Protocol, User Datagram Protocol). [0003] When the CS (Circuit Switch, circuit switc...
