US 10,771,509 B2 · Terminal interoperation using called-terminal functional characteristics

Abstract

Example techniques described herein can permit interoperation between network terminals that have different performance characteristics, or that are connected via access networks having different performance characteristics. A calling terminal (or a core network device) can retrieve an indication of functional characteristics associated with a called terminal. The indication can be included in presence information associated with the called terminal. The calling terminal can determine a altered functional specification based at least in part on the functional characteristics and a functional specification of a session. The functional characteristics can satisfy the altered functional specification. The calling terminal can initiate a altered session with the called terminal via the network based at least in part on the altered functional specification. A terminal can detect network service provided by an access network and transmit presence information to a presence-information server. The presence information can indicate a type of the access network.

Dependent claims

A method comprising, by a mobile terminal of a network:

retrieving, from an information server via the network, an indication of functional characteristics associated with a called terminal;
determining that the functional characteristics do not satisfy a functional specification associated with an initial session by which data is to be exchanged with the called terminal;
determining an altered functional specification based at least in part on the functional characteristics and the functional specification, wherein the functional characteristics satisfy the altered functional specification;
initiating an altered session with the called terminal via the network based at least in part on the altered functional specification;
downsampling content in data of the initial session;
determining altered data based at least in part on the downsampled content in the data of the initial session and on the altered functional specification;
and
transmitting the altered data to the called terminal via the network within the altered session instead of within the initial session.

At least one tangible, non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

receiving, via a network, a first invitation message from a calling terminal, wherein the first invitation message identifies a called terminal and is associated with a functional specification;
determining that functional characteristics associated with the called terminal do not satisfy the functional specification;
determining a second invitation message based at least in part on the functional characteristics and the functional specification, wherein:
the second invitation message is associated with an altered functional specification satisfied by the functional characteristics;
and
the second invitation message is associated with a communication session;
transmitting the second invitation message via the network to the called terminal;
after transmitting the second invitation message, receiving data of the communication session from the calling terminal via the network;
determining second data as at least one data chosen from altered data and upgraded data, the second data determined based at least in part on the data of the communication session;
the second data determined as altered data based at least in part on the altered functional specification, responsive to an altering operation;
the second data determined as upgraded data based at least in part on the functional specification, responsive to an altering operation in reverse;
and
transmitting the second data to the called terminal via the network.

A terminal of a telecommunications network, the terminal comprising:

a communications interface communicatively connectable with at least two access networks of respective, different types;
a user interface;
at least one processor;
and
a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
detecting, using the communications interface, network service provided by an access network;
establishing connectivity with a presence-information server via the access network;
transmitting presence information to the presence-information server via the access network, the presence information indicating a type of the access network;
receiving, via the access network, an indication of a content item and an altered content item associated with the indication, the content item and the altered content item corresponding to higher resolution content and lower resolution content, respectively;
presenting, via the user interface, the altered content item and a link or icon representing the indication of the content item;
subsequently, receiving, via the user interface, a request to retrieve the content item;
in response to the received request to retrieve the content item, retrieving, via a second access network that is different from the access network, the content item;
and
presenting, via the user interface, the content item.
