Abstract

Claims (32)

1. A method comprising:

receiving a packet data connection related request concerning a network slice being configured with a maximum number of terminals to be admitted to said network slice,

maintaining a counter indicative of a number of terminals admitted to said network slice based on said packet data connection related request, and

transmitting a response to said packet data connection related request;

said packet data connection related request is a session management policy association establishment request issued in response to a packet data unit session establishment request, wherein said session management policy association establishment request comprises at least single network slice selection assistance information identifying said network slice,

in relation to said maintaining, the method further comprises;

incrementing said counter, if no packet data unit session exists, with respect to said network slice, for a communication endpoint issuing said packet data unit session establishment request.

2. A method comprising:

receiving a packet data connection related request concerning a network slice being configured with a maximum number of terminals to be admitted to said network slice,

maintaining a counter indicative of a number of terminals admitted to said network slice based on said packet data connection related request, and

transmitting a response to said packet data connection related request;

said packet data connection related request is a session management policy association establishment request issued in response to a packet data network connection establishment request, wherein said session management policy association establishment request comprises at least single network slice selection assistance information identifying said network slice,

in relation to said maintaining, the method further comprises:

maintaining a counter indicative of a number of terminals admitted to said network slice based on said packet data connection related request, and

transmitting a response to said packet data connection related request;

said packet data connection related request is a session management policy association establishment request issued in response to a packet data network connection establishment request, wherein said session management policy association establishment request comprises at least single network slice selection assistance information identifying said network slice,

in relation to transmitting a response, the method further comprises:

determining whether said counter exceeds said maximum number of terminals to be admitted to said network slice,

deciding to accept a session management policy association establishment request according to said session management policy association establishment request, if said counter does not exceed said maximum number of terminals to be admitted to said network slice, and

sending said response including a result of deciding to accept said session management association establishment request.

4. A method comprising:

receiving a packet data connection related request concerning a network slice being configured with a maximum number of terminals to be admitted to said network slice,

maintaining a counter indicative of a number of terminals admitted to said network slice based on said packet data connection related request, and

transmitting a response to said packet data connection related request;

said packet data connection related request is a session management policy association establishment request issued in response to a packet data network connection establishment request, wherein said session management policy association establishment request comprises at least single network slice selection assistance information identifying said network slice,

in relation to transmitting a response, the method further comprises:

determining whether said counter exceeds said maximum number of terminals to be admitted to said network slice,

deciding to reject said session management policy association establishment request according to said session management policy association establishment request, if said counter exceeds said maximum number of terminals to be admitted to said network slice, and

sending said response including a result of deciding to reject said session management association establishment request.
