A method may comprise receiving subscription messages from first, second and third mobile wireless devices. A first request may be received from the first mobile wireless device, that includes at least information corresponding to a second mobile phone number of the second mobile wireless device. A first response may be sent in response to the first request. During the time between receiving the first request and sending the first response, the second mobile wireless device may not be connected to the service. The method may further comprise receiving, via the service, a first message from the first mobile wireless device, in accordance with the first response. The first message may be for the second mobile wireless device. The first message may be queued on a server associated with the service.

A method may comprise downloading a message client subsequent to receiving an SMS message and authenticating a first mobile phone number to a service for transmitting and receiving packet switched messages via SMS protocol. The method may further comprise transmitting one or more requests including at least information to determine whether a third mobile phone number and a fourth mobile phone number correspond to subscribers of the service. A response may indicate that a third mobile phone number and a fourth mobile phone number correspond to subscribers of the service. A picture message may be transmitted to a third mobile wireless device and a fourth mobile wireless device in accordance with the response.

There is provided an apparatus, said apparatus comprising means for providing, from a first function instance of a set of first function instances to a second function, first information comprising an indication that a protocol session between the first function and the second function is controllable by different instances of the set of first function instances and receiving, at one of the set of first function instances from the second function, a protocol session related message based on the first information.

A method performed by a network node, for handling an outgoing media call of a user associated with multiple User Equipment, UEs, in a communications network is provided. The network node receives (402) a request for the outgoing media call to be set up from a first UE out of the multiple UEs. The request is obtained as a voice instruction 5 from the user via a Digital Assistant, DA, device. The voice instruction comprises a personalized name associated with the first UE. The network node further identifies (403) among the multiple UEs, the first UE and its associated IP Multimedia Subsystem, IMS, identifier based on the personalized name received in the voice instruction. The network node further sends (404), to an IMS node, the identified IMS identifier of the first UE and a 10 request to whether or not the first UE is registered in the IMS node and supports media When the first UE is registered in the IMS node and supports the media of the outgoing media call, the network node initiates (405) the outgoing media call from the first UE. When the first UE is not registered in the IMS node and/or does not support the media of the outgoing media call, the network node decides (406) how to 15 proceed with the outgoing media call.

Aspects of the subject disclosure may include, for example, a system for indicating a program boundary in an adaptive bitrate media stream, where the system includes a memory and a processor that performs operations including generating multiple transcoded media output streams of different bit rates from an input linear media stream, fragmenting the multiple transcoded media output streams into chunks, detecting a program boundary in the input linear media stream, and supplying a program change indicator in a manifest file for implementing program change features in mobile communication devices. Other embodiments are disclosed.

A method performed by a first node (111) is described herein. The first node (111) operates in a communications network (10). The first node (111) sends (204) a query to a second node (112) operating in the communications network (10). The query requests information on a location of a communication device (130) operating in the communications network (10). The communication device (130) is identified by the first node (111) as a constrained communication device (130) lacking a capability to query the second node (112). The first node (111) obtains (205) the information from the second node (112), in response to the sent query, and initiates updating (207) an object in the communication device (130) based on the obtained information. A method performed by the communication device (130) is also described, whereby the device sends (301), to the first node (111), an indication that it is constrained, and obtains (304) the update.
