The present invention relates to a method and devices for operating a communication network, in particular a presence SIMPLE network applying polite block and confirm for subscribers to presence data. A method for operating a communication system comprising a presence server and a presence document server is provided, the communication system being adapted to communicate with a first client requesting subscription to the presence data of a presentity using a second client, the method comprising the steps of: sending, in case the subscription is to be confirmed or politely blocked, a request for presence data from the presence server to the presence document server; receiving a message comprising presence data of the presentity from the presence document server; and sending a notification message to the first client based on the received presence data of the presentity.

Permanent presence for polite block and confirm

A method and arrangement in a notification server () for controlling notifications with resource data to a subscribing client (A). When a subscription request is received () from the client for notifications with selected resource data of one or more resources, the access network currently used by the client is determined based on network related information, e.g. obtained from the received subscription request. The delivery of notifications () is then controlled based on the determined current network.

Method and arrangement for handling resource data

The present invention relates to methods and apparatuses for finding out which XDM server a specific user is allocated to in a network with several XDM servers. An HTTP proxy () receives an XCAP request () from an XDM client (), including information related to a user associated with the XDM client. The HTTP proxy checks if the user exists in its storage (), based on the received user information, and if not, the HTTP proxy creates a SIP request () including the user information, and passes it over to a SIP Proxy (). The SIP Proxy finds out which XDM server the user is allocated to by enquiring a subscriber database (), and then the SIP proxy passes the XDM server address information back to the HTTP Proxy (), which is then able to route the XCAP request () to the correct XDM server ().

Method and apparatus for routing XCAP requests

A method and arrangement for handling document requests in a communication services network. When a first document server () receives () a request for a first service document from a requesting party (), the requested first service document (Doc 1) is retrieved (), which comprises a reference (ref) to service related information in a second service document (Doc 2). The first document server () then fetches () said service related information (list) in the second service document using the information reference, and aggregates () the fetched service related information with the first service document. The first document server () finally returns () the first service document together with the aggregated service related information (Doc 1') to the requesting party in response to the received document request. Thereby, the requesting party is not forced to request for more documents than the first service document to obtain the needed information.

Method and arrangement for providing documents

A method, a server and a client for enabling time limited modifications of XML nodes in XML documents, where a modified document can be restored to its original content upon expiry of an expire time, which has been specified for the modification, are provided. A request for a time limited modification of an XML node, including an expire time, is transmitted from a client to a server. At the server, a timer is either started, in case no timer is pending for the XML node, or re-set, in case a timer is already pending for the XML node. The present version of the XML node is stored, before it is modified, according to modification data provided in the request. Upon timer timeout the requested modification will no longer be valid, and therefore the XML node is restored to its stored version of the XML node.

Method and arrangements for enabling modifications of XML documents

Embodiments of the present invention include a system and method for implementing a presence system. According to an embodiment of the present invention, responsive to receiving a request for presence information associated with a presentity from a watcher, the presence system receives instructions indicating that an authorization instance other than the presentity shall be given an opportunity to change or verify an authorization rule associated with the request for presence information. As a consequence, the presence system notifies the authorization instance of the request for presence information, thereby enabling the authorization instance to change or verify the authorization rule. The presence system also makes a final decision on the authorization rule on the basis of the instructions and a notification indicating a change or verification of the authorization rule.

Method and system for authorization of presence information

A method enabling a service at a communication network node and a network node adapted to execute the method is provided, wherein a first request, requesting for one or more operations to be associated with a symbol, is received from a first user. The request comprises an instruction, identifying one or more operations. The request triggers the generating of a unique symbol identity, and the creation of a symbol record, associated with the symbol identity, wherein the symbol record, linking the symbol identity to the one or more operations. At the node the symbol identity is also associated with the generated symbol, which is created by a symbol server and forwarded to the first user. Once the symbol has been received by the node in a second request, the symbol identity corresponding to the symbol is retrieved from the symbol server, and the service is enabled by executing the one or more operations according to the symbol record identified by the symbol identity.

Method of enabling a service at a communication network node

Systems and methods for publishing presence information can be performed to reduce the amount of signaling associated with presence publication. A method for publishing presence service information to a presence server includes: receiving, at a registrar node, a session initiation protocol (SIP) message originated by a user equipment (UE) over the air interface; and transmitting a third party register message based upon the received SIP message, from the registrar node, toward a presence server using network signaling, wherein the third party register message includes at least one of information associated with the user of the UE, capabilities of the UE and presence related services offered by the UE.

Methods and systems for presence publication using SIP register feature tags

Systems and methods for reactively authorizing publication of information by a third party are coordinated through the use of a presence server. The presence server communicates with other communication nodes/devices to determine and relay publication information. Publication requests that are initially unauthorized, from the perspective of the presence server, are resolved.

Reactive authorization for publications

The invention provides a method of authorizing provision of in-directed content to a user of an IPcommunications network. The in-directed content is associated with a presentity subscriber of a presence service, the presence service including authorization rules regarding users to which the in-directed content may be provided. The in-directed content is stored at a content server that is not controlled by the presence service. The method includes receiving at an authorization proxy in the network a request from the user to be provided with the in-directed content, and identifying the presentity subscriber associated with the requested in-directed content. The authorization proxy retrieves the authorization rules to verify that the user is authorized to receive the in-directed content. Subject to the verification, the in-directed content is provided from the content server the user.
