Patent ID: 8266309

Claim:
A method for querying parameter information, comprising: receiving, by a first protocol layer of a terminal, a query request for a plurality of parameters from a second protocol layer of the terminal; obtaining, by the first protocol layer of the terminal, parameter values of the plurality of parameters according to the query request; establishing, by the first protocol layer of the terminal, a first correspondence between a parameter value and a parameter name corresponding to each parameter of the plurality of parameters; and returning, by the first protocol layer of the terminal, the parameter value and the parameter name corresponding to each parameter of the plurality of parameters to the second protocol layer of the terminal according to the first correspondence; returning, by the first protocol layer of the terminal, status of query result of each parameter of the plurality of parameters to the second protocol layer of the terminal, wherein the second protocol layer of the terminal, after receiving the parameter value and the parameter name corresponding to each parameter of the plurality of parameters sent from the first protocol layer of the terminal according to the query request of the second protocol layer of the terminal, acquiring a state value according to the status of query result of each parameter of the plurality of parameters; establishing a second correspondence between the state value and the parameter name corresponding to each parameter of the plurality of parameters; and returning the state value and the parameter name corresponding to each parameter of the plurality of parameters to a third protocol layer of the terminal according to the second correspondence, wherein the third protocol layer of the terminal is any one of: an upper layer, MIH users, or a network management system (NMS) entity.
