Abstract: A multicast broadcast service (MBS) management method, device, and system are provided, so that a service/content provision server is enabled to manage an MBS operated by the service/content provision server itself. The method includes: a universal service interface (USI) receives a management operation request message from a service/content provision server; the management operation request message is sent to a multicast and broadcast service (MCBCS) server/controller to enable the MCBCS server/controller to perform corresponding operations according to the management operation request message. The device includes a first receiving module and a second receiving module. Another device includes a receiving module and a request processing module. The system includes an MCBCS server/controller and a USI connected to the MCBCS server/controller in a communication mode.

Abstract: In the field of communication technology, a method for invoking a Universal Service Interface (USI) and a USI system are provided. The schemes provide a user with a short-lived user ID for the application to interact with the USI system. The short-lived ID has a corresponding relation with the long-lived user ID and can be found according to the long-lived user ID regardless of whether the user is online or offline. The method and device can effectively ensure the security of USI invocation, and ensure that the application can initiate the USI service request even when the user is in an offline state.

Abstract: A method for data transmission includes: a router receives a data packet sent by an access device of a first user, where the data packet carries target device selection information including at least a user identity of a second user, and the user identity is associated with at least one access device of the second user; the router obtains a routing address of an optimal access device among access devices associated with the user identity; and the router sends the data packet to the optimal access device according to the routing address.

Abstract: Embodiments of the present disclosure disclose a user-oriented communication method, a route registration method and device, and a communication system. In the method, a first domain router receives a first data packet sent by a first terminal. The first data packet includes a user identifier of a first user and a user identifier of a second user, the first terminal belongs to the first user, and a second terminal belongs to the second user. The first domain router queries for a second domain router connected to the second terminal according to the user identifier of the second user and sends the first data packet to the second domain router, so that the second domain router sends the first data packet to the second terminal.

Abstract: A method, a server, and a system for configuring a paging group (PG) and a neighbor cell list of a femto access point (FAP) are provided. The method includes: receiving a configuration request from a security gateway or an FAP; acquiring location information of the FAP; determining an access service network gateway (ASN-GW) accessed by the FAP, and notifying the location information of the FAP to the ASN-GW, so that the ASN-GW allocates a PG to the FAP according to the location information of the FAP, and delivers an identifier (ID) of the allocated PG; and receiving the ID of the PG from the ASN-GW, and delivering the ID of the PG to the FAP. Therefore, the FAP can dynamically join into a PG and the neighbor cell list can be dynamically updated.

Abstract: A method, an apparatus, and a system for registering in a USI system are disclosed herein. The method includes: an H-USI system receives a USI registration request message that carries an identifier of a terminal from a V-USI system; and the H-USI system interacts with an H-AAA server according to the USI registration request message to perform USI system registration for the terminal. An apparatus for registering in a USI system is disclosed herein. The apparatus includes a receiving module and a registering module. Through the method and the system disclosed herein, the terminal can be registered in the USI system successfully, and the USI service can be implemented smoothly.

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: 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: The present invention discloses a method for providing presence information, including: setting a validity period of the presence information; publishing, by a presentity client, the received presence information and the validity period to a presence server; and distributing the received presence information and the validity period to a watcher client by the presence server. Thus, the watcher client knows the validity period of the presence information, such as an end time of a current presence time, and thereby selects timely an appropriate time for communication with the presentity client. Furthermore, the present invention also provides a start time of the current presence information, and thus the watcher client knows a duration of the current presence information of the presentity client. The present invention further discloses a system for providing presence 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.
