Abstract:
1. A method for implementing resource management, for setting up a service connection between a source user device and a destination user device, used among at least one border Call Agent (CA) and at least one bearer network resource manager, wherein each bearer network resource manager corresponds to one administration domain, each administration domain corresponds to at least one border CA and one or more bearer network resource managers, and the administration domain to which the source user device belongs corresponds to a source border CA and a source bearer network resource manager while the administration domain to which the destination user device belongs corresponds to a destination border CA and a destination bearer network resource manager, comprising: sending, by the source border CA, a connection resource request to the source bearer network resource manager; determining, by each bearer network resource manager that has received the connection resource request, whether the bearer network resource manager itself is the destination bearer network resource manager, if yes, applying for connection resources for the service connection currently being set up and sending back a resource application response to the destination border CA, otherwise, preprocessing the resource application of the service connection currently being set up and returning a response of preprocessing to the border CA corresponding to the bearer network resource manager; sending, by each border CA that has received the response of preprocessing, the connection resource request to its next-hop border CA; sending, by each border CA that has received the connection resource request, a connection resource request to its corresponding bearer network resource manager; and each border CA which has received the resource application response judging whether the border CA itself is the source border CA, if yes, instructing the source bearer network resource manager to apply for connection resources for the service connection currently being set up, otherwise, instructing the corresponding bearer network resource manager to apply for resources for the service connection currently being set up, and then sending back the resource application response to its last-hop border CA.
