Abstract

In a connection management system for setting up connections in a communications network, run-time negotiation is carried out to avoid feature interaction. Users of the network are provided with user agents (intelligent software) which have access to user profiles. When a calling user wants to set up a particular connection configuration, which may involve service features such as ring back later on busy, their user agent sends a connection configuration proposal to the user agent for a called user. The two user agents then negotiate to establish a mutually acceptable connection configuration, if one is available. The negotiation is based on alternative connection configurations stored in order of preference in the respective user profiles. These are proposed and counter-proposed by the user agents in descending preference order until the mutually acceptable configuration is reached or the connection fails.

Claims

1. A method of establishing a connection over a communications network, for service provision between first and second users of the network, there being provided respective connection set-up means for said users, which method comprises:

i) storing for each of said users data defining at least one connection configuration, said connection configuration comprising at least one operation of the communications network in combination with an operation to be implemented at least in part by functionality of the connection set-up means;

ii) storing in respect of data defining a connection configuration for the second user, data defining at least one alternative connection configuration; and

iii) storing in respect of said data defining a connection configuration for the second user, and in respect of the data defining the or each of its alternative connection configuration(s), a respective priority indicator;

the method further comprising a negotiation process for the establishment of a connection by means of;

iv) transmitting data defining a proposed connection configuration from the connection set-up means for the first user to the connection set up means for the second user, said proposed connection configuration comprising at least one of an operation of the communications network and an operation to be implemented at least in part by functionality of the connection set-up means for the first user;

v) reviewing the data defining the proposed configuration at the connection set-up means for the second user by accessing the data defining configurations and the respective priority indicators stored in respect of the second user; and

vi) selecting and transmitting a response to the connection set-up means for the first user, the response being determined at least in part by the result of the review step v) above, and selected from acceptance or rejection of the proposed connection configuration, or comprising data defining a counter-proposed connection configuration, without having access to the stored data defining at least one connection configuration in respect of the first user.

2. A method according to claim 1 wherein the data defining an operation to be performed at least in part by the connection setup means comprises time data and, in the event that the response is acceptance of a connection configuration comprising time data, the connection setup means subsequently attempts to set up a connection in accordance with said time data.

3. A method according to claim 2 wherein said time data comprises a time of day and the connection setup means subsequently attempts to establish connection at that time of day.

4. A method according to claim 2 wherein said time data comprises a time interval and the connection set up means subsequently attempts to establish connection after said time interval has passed.

6. A method according to claim 5 wherein steps v) through viii) are carried out, and repeated if necessary, until a transmitted response is acceptance or rejection of a proposal.

7. A method according to claim 6 which further comprises the step of logging, by the connection setup means for each user and at least for the duration of a single negotiation process, received connection configuration proposals, any subsequent proposal transmitted by either connection set up means excluding proposals previously transmitted by either connection setup means.

8. A method according to claim 1 which further comprises the step of storing, for each of said users, any current data relevant to connection setup for that user, in addition to data defining connection configurations, and the negotiation process further comprises the step of reviewing the additional data prior to transmission of data defining a proposed or counter-proposed connection configuration, and modifying the data defining a proposed or counter-proposed connection configuration accordingly.

9. A method according to claim 8 wherein the additional data comprises one or more of the following:

a) connection mode data;

b) location data for the relevant user with respect to the network;

c) commitment data, indicating commitments previously made by the relevant user; and

d) concurrent negotiation process data for the relevant user.

10. A method according to claim 6 wherein the data defining each proposed or counter-proposed connection configuration transmitted from a connection setup means is selected for transmission in accordance with a progression from proposals with a high priority indicator towards proposals with a relatively lower priority indicator, for the relevant user.

11. A method according to claim 1 wherein each connection setup means can be provided for a plurality of users and wherein the method can be carried out concurrently by a connection setup means for more than one user.

12. A method according to claim 1, wherein each connection configuration comprises one or more features providing a component of a communications service, the features being selected from a set of features at least two of which are mutually incompatible.

13. An apparatus for use in establishing a communications connection between a first access point and at least one further access point of a communications network, the apparatus comprising connection set-up means associated with said first access point, the apparatus further comprising:

an interface to the communications network for activating network operations available at said first access point;

a data store for storing data defining at least one connection configuration and an associated priority indicator in respect of said first access point, said connection configuration comprising at least one operation of the communications network in combination with an operation to be implemented at least in part by functionality of said connection set-up means;

wherein said connection set-up means comprise;

means to implement a negotiation process, in co-operation with connection set-up means associated with said at least one further access point, to agree a set of operations of the communications network and of said connection set-up means for implementing said communications connection; and

means to implement said agreed set of operations in respect of said first access point;

said negotiation process comprising the steps of;

(i) receiving data defining a proposed connection configuration;

(ii) reviewing the received data in comparison with connection configuration data and priority indicators stored in the data store; and
