Abstract

The present invention relates to a method and an electronic equipment for reducing the set-up time required to establish video calls between handheld communication devices, wherein the method comprises the steps of detecting (16, S1) a signal to establish a video call via a communication link, determining (16, 30) the party to which the video call has to be established, searching, in a data base (30), for information indicating the capability of the party with respect to the video call, defining, for the electronic equipment (1), specifications for the video call based on the information, and initialling the electronic equipment (1) according to the specifications. By storing the negotiated result of a previous video call between communication devices, no further negotiation is necessary in the following video calls. The calling device can start its camera (8) and load its codecs during the calling phase and the called device can do it after receiving the set-up message from the network.

Claims

1. Electronic equipment for a communication system enabling video calls, comprising

detecting means for detecting a signal to establish a video call via a communication link;

determining means for determining a party to which the video call has to be established;

means for searching, in a database, for information indicating the capability of said party with respect to the video call;

means for defining, for the electronic equipment, specifications for said video call based on said information;

means for initialling the electronic equipment according to said specifications; and

said electronic equipment being configured to transmit, during establishment of the video call, a usage command requesting the party to use a stored negotiated result of a previous video call, and

to selectively transmit electronic equipment information on capabilities of the electronic equipment to said party if a response to said usage command received from said party indicates that said party rejects the request to use the stored negotiated result.

2. Electronic equipment according to claim 1, further comprising means for updating said database, wherein said database includes a list of recipient data with respect to previous communications, which indicates recipient addresses, transmission methods and types of the transmitted information content.

3. Electronic equipment according to claim 2, further comprising means for acquiring recipient data from another communication device, wherein said updating means is adapted to update said database based on the acquired recipient data.

4. Electronic equipment according to claim 1, wherein said communication system is a wireless communication system and said electronic equipment is a mobile radio terminal.

5. Electronic equipment according to claim 1, wherein said communication system is a wireless communication system and said electronic equipment is a mobile phone.

6. A method for an electronic equipment enabling video calls in a communication system, comprising the steps of:

detecting a signal to establish a video call via a communication link;

determining a party to which the video call has to be established;

searching, in a database, for information indicating the capability of said party with respect to the video call;

defining, for the electronic equipment, specifications for said video call based on said information;

initialling the electronic equipment according to said specifications;

transmitting, during establishment of the video call, a usage command requesting the party to use a stored negotiated result of a previous video call,

whereby electronic equipment information on capabilities of the electronic equipment is selectively transmitted to said party if a response to said usage command received from said party indicates that said party rejects the request to use the stored negotiated result.

7. A method according to claim 6, further comprising

a step of updating said database, wherein said database includes a list of recipient data with respect to previous communications, which indicates recipient addresses, transmission methods and types of the transmitted information content.

8. A method according to claim 7, further comprising

a step of acquiring recipient data from another communication device, wherein in said updating step said database is updated based on the acquired recipient data.

9. Computer program product directly loadable into the internal memory of a communication device enabling video calls in a wireless communication system, comprising software code portions for performing the method steps of claim 6 when said product is run in said communication device.
