Handling of policy and charging information and user profiles in a multisite communication's network

摘要

It is provided a method for handling policy and charging information, PCI, relating to a user, wherein the method is carried out in a communications network comprising a first and a second site at least (S1, S2). Each of these sites comprises at least a policy and charging rules, PCR, network entity. The method comprises sending (SI1O) from a first network entity of a first site (110; AF-1; PCEF-1) to a PCR network entity of said first site (PCRF-1) a request to obtain PCI dependent on a user profile; generating—if it is determined that said user profile is not accessible at the first site (PCRF-1)—a redirection message comprising an identity of the PCR network entity of the first site (PCRF-1); forwarding said redirection message to a PCR network entity of said second site (PCRF-2).

1. A method for handling policy and charging information relating to a user, the method carried out in a communications network comprising at least a first site and a second site, each of the first and second sites comprising at least a policy and charging rules (PCR) network entity, the method comprising: receiving, at the PCR network entity of the second site and from a first network entity of the first site, a request to obtain policy and charging information dependent on a user profile of a user accessing the communications network from the first site, wherein the request comprises at least an identity of the PCR network entity of the first site; if the user profile is not accessible at the PCR network entity of the second site: generating a redirection message based on the request, the redirection message comprising the identity of the PCR network entity of the first site, the identity of the PCR network entity of the second site, and an identity of a PCR network entity of a third site; and forwarding the redirection message to the first network entity of the first site; and if the user profile is accessible at the PCR network entity of the second site: sending a message indicating that the user profile is accessible at the PCR network entity of the second site from the PCR network entity of the second site to the first network entity of the first site and to the PCR network entity of the first site.
