摘要： A method for over-the-top (OTT) management in a communication network is presented. The method is performed in an application client. The method comprises sending a request for activation of a policy for an application network interaction protocol (ANIP) service to a packet data network gateway (PGW) wherein the request indicates an address to a local ANIP server; receiving a set of rules related to the requested activation of the policy from the PGW, wherein the set of rules are defined for a packet data network (PDN) session applicable for the ANIP service; and communicating over the communication network based on the received set of rules. Methods, application clients, PGWs, ANIP servers, computer programs, and a computer program for OTT management in a communication network are also presented.

摘要： The method comprises sampling transport data received on the transport link to determine properties of the transport link. The method comprises detecting the disturbance of the transport link based on the determined properties of the transport link. The method comprises, responsive to the detecting the disturbance, determining, based on the sampled received transport data, the cause of the disturbance. The method further comprises, responsive to detecting the disturbance, refraining from transmitting an indication of the disturbance or transmitting the indication of the disturbance with an instruction for resolving the disturbance.

摘要： A server (500), a client device (502) and methods therein, for handling cached content resources. When receiving (5:3) a request from the client device (502) in a downloading session, the server (500) identifies (5:4) a set of caches (504, 506) that can be accessed by the client device (502). The server (500) then sends (5:6) a cache map to the client device (502) indicating that a first content resource is stored in a first cache (504) of the identified set of caches and a second content resource is stored in a second cache (506) of the identified set of caches. Thereby, the server (500) is able to adapt the cache map depending on which caches can be accessed by the client device (502), to ensure that the client device (502) can retrieve the content resources in an efficient manner.

摘要： A server (600), a client device (602) and methods therein, for handling cached content resources. When the client device (602) sends a download request (6:3) in a downloading session, the server (600) identifies (6:4) at least one content resource deemed to be potentially needed later in the downloading session. The server (600) then sends a cache map to the client device (602) in a response to the download request. The cache map comprises a pre-fetch indication indicating that the identified at least one content resource should be pre-fetched by the client device (602) from a cache (604) containing the identified at least one content resource. Thereby, the client device is able to pre-fetch (6:8) the content resources before the performance of communication may become reduced so that communication with the cache (604) is difficult or even impossible, e.g. due to deteriorated radio conditions or congestion in the communication network.
