Abstract: A method for processing presence information is disclosed. Presence information includes different values of a presence element, classes corresponding to the values and presentity information. Authentication configuration information of a presentity is obtained according to the presentity information. A right rule is obtained by resolving the authentication configuration information. The right rule includes a correlation configured by the presentity between a watcher identity and a class of a group that the watcher identity pertains to. A value of the presence element is sent to a corresponding watcher according to a correlation between the class corresponding to the value in the presence information and the class derived from the right rule obtained from the authentication configuration information.

Abstract: An Extensible Markup Language (XML) document management method includes: receiving an XML document management operation request sent via an XCAP protocol, by an XML Document Management Server (XDMS); determining that the XML document management operation request is in an entrustment mode, and determining whether to perform an operation described in the XML document management operation request in accordance with access permission information corresponding to an XML document, by the XDMS.

Abstract: A method for processing presence information is disclosed. Presence information includes different values of a presence element, classes corresponding to the values and presentity information. Authentication configuration information of a presentity is obtained according to the presentity information. A right rule is obtained by resolving the authentication configuration information. The right rule includes a correlation configured by the presentity between a watcher identity and a class of a group that the watcher identity pertains to. A value of the presence element is sent to a corresponding watcher according to a correlation between the class corresponding to the value in the presence information and the class derived from the right rule obtained from the authentication configuration information.

Abstract: The present invention discloses a method for realizing presence service. By recording a correlation between a watcher identity and a class in an authentication configuration information of a presentity for a watcher and making presence information related to a corresponding class in the presence information issued by the presentity, a presence server determines that presence information may be obtained by the watcher according to a correlation between classes and watcher identities and presence information. The invention further discloses a system for realizing presence service, a presence information processing device and a presentity client.

Abstract: A method, a device, and a system for implementing resource sharing through a user management device are provided.

Abstract: The present disclosure discloses a mail conversion method, a mail retrieval method, a mail server, a mail client device, and a mail system. The mail conversion method includes: converting a received mail according to the instruction of a CONVERT operation in a preset mail filtering language (SIEVE); and relating the original mail before conversion to the target mail after conversion. With the present disclosure, non-real-time conversion of a mail is enabled, and the time for a client user to retrieve the converted mail is saved.

Abstract: An extensible markup language document management method includes: receiving a document recovery request from a user; and recovering a version of the document as required by a user from the current version of the document, in accordance with the change records for the document. An extensible markup language document management system includes: a rollback control module, adapted to recover a version of a document as required by a user from the current version of the document, in accordance with change records for the document, upon receiving a document recovery request from the user.

Abstract: A method, a system, a document management server, a presence server and a delegation check processing unit for setting configuration information of a presentity client are used to solve the problem that the setting of configuration information must be done by a presentity client and cannot be delegated to other entities. The method for setting configuration information of a presentity client includes the processes of: determining a configuration request message sent from a configuration request sender is in delegation mode; confirming qualification of the configuration request sender according to delegation setting authorization rules set by the presentity client; and setting the configuration information of the presentity client according to the configuration request message.

Abstract: A method for delegated transmission/reception of a Session Initiation Protocol, SIP, message, where delegation related header fields or header field parameters are extended in the SIP message and a SIP processor processes the message according to the extended header fields or header field parameters to implement the delegation function at the SIP layer. Accordingly, an SIP processor is provided. Because delegation is implemented at the SIP layer, the delegation mechanism is independent of services and therefore can be applied to different services. This facilitates multiplexing and uniform management of the delegation function.

Abstract: A method of managing an Extensible Markup Language (XML) document is provided. The method includes a XML server receiving the request of XML document management operation sending from the XML Document Management (XDM) client. The request carries the document identifier and the state information. The XDM server changes the state of the document corresponding to the document identifier to the state that corresponding to the state information.

Abstract: A method and system for establishing a group session and a service server are disclosed. The method comprises: acquiring a group member list and establishing session conditions according to the information in a received group session; acquiring the various information described in the establishing session conditions; determining group members of which the various information meets the establishing session conditions; and sending a request for establishing a group session of which the various information meets the establishing session conditions, and establishing the group session. The method solves the problem that the service server cannot dynamically select the group members, according to the current statuses of the group members, to establish the session in the prior art, whose disadvantages are the session is inflexible and the communication resources are wasted.

Abstract: A system and method for realizing group talk QoE includes the following: a group talk control server determining the group talk QoE type according to preset QoE type corresponding with a group when group talk is established; and the group talk control server configuring the established talk characteristic, according to the QoE type corresponding with the group. A system for realizing group talk QoE includes a user device, a shared group server for storing group information and a group talk control server.

Abstract: A method for querying user information includes: A search proxy receives a query request containing query conditions sent from a client, and forwards a message of the query request to the XDM server in which the user information is stored. The search proxy receives the query result returned from the XDM server, and subscribes to the user URI presence information from the presence server. The user URI presence information is contained in the query result. The search proxy integrates the presence information returned from the presence server with the query result, and sends an integration result to the client. Thus, a user can obtain the user information when he/she obtains the user information in XDM.
