Abstract: In the field of communications, a method, a system, and a device for searching for information, and a method for registering a vertical search engine are provided. The method for searching for information includes the following steps. A first search request sent by a user is received. A logic node is determined according to attribute information in the first search request. A vertical search engine selected by the logic node for the user is received. A second search request is sent to the vertical search engine. The method for registering the vertical search engine includes the following steps. A mobile search server receives and saves first registration information sent by the vertical search engine. Location information of a logic node corresponding to the vertical search engine is determined according to the first registration information. Second registration information is sent to the logic node according to the location information.

Abstract: A method, a system, and a device for implementing media negotiation are provided. The method includes the following steps. A caller sets media levels, and sends a request carrying the media levels to a callee. After receiving a response carrying media selected by the callee according to the media levels returned from the callee, the caller performs corresponding processing according to the media selected by the callee. Through the method, the caller sets primary and optional media types and specifies the levels of each media type during the media negotiation process. Thus, the additional media information improves the efficiency of the media negotiation of a session.

Abstract: The present disclosure discloses a method, system and apparatus for storing and querying session history records. The method for storing session history records includes: receiving a request from the first server at the user side; judging whether the request carries a storage indication; if the request carries a storage indication, judging whether to store the session history records to be saved according to the storage policy. In the embodiments of the present disclosure, the storing of the session history records is managed uniformly, and the history record information of a session is stored only in the corresponding storage apparatus at the second server side rather than being stored in the network storage apparatus at each first server side, thus overcoming the defects of the prior art, namely, waste of network storage space and redundancy of stored information.
