Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for communicating messages between network elements.

Background

At present, message communication mechanisms used in a base station are all self-defined communication mechanisms inside network elements, and TCP (Transmission Control Protocol) and UDP (User Data Protocol) links for communication inside a board card and between the board cards are all head links with self-defined OSP (Operating system platform) message headers.

The current base station communication mechanisms are mainly divided into the following three types:

1. In-process communication: in an SMP (symmetric multi-Processing) Linux System, an API (application programming Interface) function provided by a posix (Portable Operating System Interface) is used for intra-process communication, and a thread in a process realizes message communication through a message queue;

2. Inter-process communication: in an SMP Linux system, interprocess communication is also realized through an API function provided by posix, and because all sent addresses are message memory addresses, interprocess message content copying needs to be carried out through an interprocess shared memory pool, and then message addresses are sent for communication;

3. Communication between boards: and the inter-board communication calls a bottom-layer network card driver to directly send the message, and the message is exchanged to a target board card through Ethernet to realize message communication.

In the current base station communication system, because the message source and the message destination are both in the same network element, a customized OSP (Operating system platform) message header is added in front of the message content, and a user determines the processing task of the message by filling in a source sfu (software Function unit) and a destination sfu in the OSP message header.

the specific data structure is as follows:

And calling a platform registered message sending function Osp _ Send _ Msg () interface to Send the message after the user fills in the OSP message header. The Osp _ Send _ Msg () function decides whether to Send a message through a posix interface or Send a message through a network card driver according to the transmission source and destination input by the user. If the target sfu task is an in-process or inter-process message, finding a corresponding message queue ID directly according to a target task ID filled by a user, calling a posix layer message sending function, and directly hanging the message queue of the target sfu; if the target sfu task is on another board card, the sending function can calculate the IP and MAC address of the target board card according to the ID of the target board card, and then the sending function of the driver is called to send the user data to the target board card through the internal network.

And the user side receives the message through an Osp _ Msg _ Receive () interface, and the message received by the posix interface is encapsulated inside the function. When no message exists in the communication between the processes, the task is in a blocking state, and when the message is hung in the message queue, the kernel directly awakens the receiving task to start processing the message content. The received message is driven by the network card, and because the data received by the network card contains an OSP message header filled by a user, the network card receiving task finally calls a posix sending function to Send the message to the receiving task of the local card by calling the Osp _ Send _ Msg (), and the Osp message header is internally analyzed.

As can be seen from the above, in the prior art, in the message sent through the driver link, the driver calculates the IP address of the opposite end according to the purpose filled by the user, and there is a possibility that the IPs between the network element units may conflict, so that the message communication between the network elements cannot be performed.
