METHOD AND DEVICE FOR CONDITIONAL ACCESS
Methods, devices, and computer program products facilitate access to, and usage of resources within, a radio network. A conditional access framework incorporates myriad technologies ranging from authentication, session control, Internet Protocol (IP) packet inspection to resource allocation by airlink schedulers. Such an end-to-end control enables effective implementation of conditional access paradigms by ensuring service guarantees for authorized users while resulting in a certain level of service availability to guest users.
1 . A method, comprising:
assigning weights to a plurality users of a radio network, each of the plurality of users being categorized within one of a plurality of classes;
allocating radio network resources to a user pursuant to the weight associated with the user.
2 . The method of claim 1 , wherein
the radio network is configured within a larger radio network;
the plurality of users comprise one or more users of the larger radio network that are unknown to the radio network; and
the one or more users of the larger radio network request one or more services from the radio network.
3 . The method of claim 1 , wherein the plurality of classes comprise an authorized class of users with a preferential level of radio network service.
4 . The method of claim 3 , wherein a user within the authorized class of users is identified in accordance with an identifier within an internet protocol (IP) packet associated with the user within the authorized class of users.
5 . The method of claim 1 , wherein the plurality of classes comprise a guest class of users with a conditional level of radio network service.
6 . The method of claim 1 , wherein a weight is assigned to each individual user of the radio network.
7 . The method of claim 1 , wherein a weight is assigned to each group of users of the radio network within a particular class.
8 . The method of claim 1 , wherein a weight is assigned to each class of users of the radio network.
9 . The method of claim 1 , wherein radio network resources are allocated in proportion to the assigned weights.
10 . The method of claim 1 , wherein the radio network resources comprise a bandwidth, a time slot, a carrier frequency or a transmission power associated with the radio network.
11 . The method of claim 1 , wherein the allocating comprises:
selecting a class of users; and
allocating radio network resources to a plurality of users within the selected class.
12 . The method of claim 11 , wherein the selecting is carried out in accordance with a probability value.
13 . The method of claim 11 , wherein the selecting is carried out deterministically in accordance with a number of user classes and weights associated with the plurality of user classes.
14 . The method of claim 11 , wherein the selecting is carried out in accordance with a history of previously selected user classes.
15 . The method of claim 11 , further comprising:
determining if additional radio network resources are available;
selecting a different class of users; and
allocating radio network resources to a plurality of users within the different class of users.
16 . The method of claim 1 , further comprising:
setting a maximum level of radio network resources consumed by at least one user of the radio network.
17 . The method of claim 16 , wherein the maximum level of radio network resources comprises a maximum data rate.
18 . The method of claim 1 , further comprising controlling admission to the radio network pursuant to the assigned weights.
19 . The method of claim 1 , further comprising modifying an allocated radio network resource to an authorized user by changing a weight associated with the authorized user when the authorized user is in communication with one or more radio nodes.
20 . The method of claim 1 , further comprising modifying, on a per-radio-node basis, an allocated radio network resource to a particular class of users by changing a weight associated with the particular class of users when the particular class of users are communicating through one or more radio nodes.
21 . The method of claim 20 , wherein the one or more radio nodes designate a particular geographic location.
22 . The method of claim 1 , where allocating the radio network resources is carried out pursuant to the number of additional users within the radio network.
23 . The method of claim 16 , wherein the user is an authorized user of the radio network and the additional users are guest users of the radio network.
24 . The method of claim 1 , further comprising
configuring a list of users associated with at least one of the plurality of classes, wherein a user within the configured list is identified in accordance with a unique identifier.
25 . The method of claim 24 , wherein the unique identifier is an international mobile subscriber identity (IMSI).
26 . A device, comprising:
a processor; and
a memory comprising processor executable code, the processor executable code, when executed by the processor, configures the apparatus to:
assign weights to a plurality users of a radio network, each of the plurality of users being categorized within one of a plurality;
allocate radio network resources to a user pursuant to the weight associated with the user.
27 . A computer program product, embodied on a computer readable medium, comprising:
program code for assigning weights to a plurality users of a radio network, each of the plurality of users being categorized within one of a plurality of classes;
program code for allocating radio network resources to a user pursuant to the weight associated with the user.
