Problems solved by technology
If an exception occurs during the process of modifying the tunnel, the tunnel parameters of different network elements will be inconsistent, so that the service data of the terminal cannot obtain the quality of service that the modified tunnel should be able to provide in some network elements.
[0010] 4) In the existing LTE wireless communication system, when the terminal initiates a tunnel operation request, if the signaling interaction is abnormal or the network element is restarted, the context of the network element is lost, and the abnormal network element receives the service data of the terminal , the user's context cannot be found, the user's data will be discarded, and there is no exception recovery mechanism

Embodiment Construction
[0029] The solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0030] The detailed description of the tunnel creation scheme is as follows image 3 Shown:
[0031] 1) When the tunnel management network element receives the terminal’s request to establish a tunnel, it writes all the parameters of this transaction into the database, and the database generates the unique index value of the parameter, and the tunnel management network element takes the unique value index value as Transaction flag.
[0032] 2) Send the transaction flag and the operation type (establishment) to the tunnel in parallel to the network elements of the access network, the core network and the terminal.
[0033] 3) The network element of the access network, the data plane network element of the core network, and the terminal receive the transaction flag and the operation type (establishment), and obtain the parameters corresponding to t...

The invention relates to a network element parameter configuration method for use in a wireless communication system. The method comprises the following steps: recording configuration parameters in a database; generating unique index values of the parameters by using the database; configuring network elements in parallel or in series by a configuration initiator; and unifying configuration interfaces as operation types and the unique index values of the parameters in the database. Through use of the scheme of the invention, the problems of sequence limitation on signaling flows, complex exception handling flows and the like during the establishment, modification and deletion of channels are solved.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a method for network element parameter configuration and network element error self-recovery in the wireless communication system core network and access network. Background technique [0002] In an existing wireless communication system, the overall network architecture includes three parts, namely a terminal, an access network and a core network. The access network mainly includes network elements such as base stations, and the core network includes network elements such as mobile management entities (MME) and gateways. For example, in an LTE system, when a terminal initiates the establishment of a dedicated tunnel, it needs to initiate a tunnel establishment request to the core network MME network element; when the MME receives the tunnel establishment request, it needs to initiate a tunnel establishment request to the core network data plane network element, and send the...
