Embodiments of the present invention disclose a method for content categorization, where the method comprises transmitting, by a content categorization request entity, a categorization ability negotiation request to a content categorization providing entity to request the categorization ability of the content categorization providing entity; receiving the categorization capability of the content categorization providing entity returned by the content categorization providing entity. Furthermore, embodiments of the present invention disclose a system for content categorization, content categorization request entity and content categorization providing entity. Categorization ability negotiation or subscription helps to learn the content categorization ability so that the content categorization request entity or content categorization providing entity may mutually and accurately acquire content categorization capability information without delay.

Method and system for content categorization

The invention discloses a method and system for content categorization, which aims at reducing the processing burthen of the content categorization as well as the network transmission traffic. The method comprises: transmitting, by a content categorization requester, a content digest of a content to be categorized to a content categorization provider; and performing, by the content categorization provider, content categorization according to the content digest. The device for requesting content categorization comprises: a digest operation determination component, adapted to determine whether it is necessary to obtain a content digest of a content to be categorized; a digest obtaining component, adapted to obtain the content digest of the content to be categorized when the digest operation determination component determines it necessary to obtain the content digest of the content to be categorized; and a first transmit component, adapted to transmit the content digest obtained by the digest obtaining component.

A method for sharing reverse channel in trunk communication system includes: step A, establishing a forward channel and one or more in a group: step B, mobile stations in idle state determine a sharing reverse channel that can be used based on information of the sharing reverse channel; step C, the mobile station transmits information through the sharing reverse channel. Furthermore a system for sharing reverse channel in trunk communication system includes: channel establishing means, for establishing a forward channel and one or more in a group; reverse channel determining means, for determining a sharing reverse channel that can be used by a mobile station based on the information of the sharing reverse channel; reverse channel information transmitting means, for transmitting information through the sharing reverse channel. This invention saves the air and physics sources of the system, and reduces the collision probability of the signaling of each mobile station in idle state.

Method and system for sharing reverse channel in trunk communication system

A method for realizing forward channel sharing in time division communication system, which completes group configuration at the cluster control service center server and modifies the attributes of all the users to enable the users to support multi-user packet MUP service, including: (a) the cluster user initiates a group call; the access network allocates a unique group identifier MACIndex for the group call after receiving the call request from the calling cluster user and informs all of the users within the group about this MACIndex (); (b) after the communication starts (), the access network packets the user data of one or more groups with multi-user packet MUP, packets the user data of each group into one sub-packet and does scheduling, then transmits the packets through forward channel (); (c) after receiving the MUP packets from the forward channel, the cluster user looks into the MUP packets for the sub-packet that matches the MACIndex of its group, thereby realizing group communication (). The present method solves the problem of system delay and supports even more groups.
