Abstract

Systems, methods, and process nodes for managing device connections in a telecommunications network perform and/or comprise: receiving a connection request from a wireless device at a first Public Land Mobile Network (PLMN) of the telecommunications network; comparing a capability report of the wireless device to a predetermined criteria, wherein the predetermined criteria corresponds to whether the wireless device is compatible with the first PLMN; and in response to a determination that the capability report meets the predetermined criteria, denying the connection request.

Claims (39)

1. A method of managing device connections in a telecommunications network, the method comprising:

receiving, by a first device, a connection request from a wireless device, wherein the first device is a component of the telecommunications network;

comparing a capability report of the wireless device to a predetermined criteria, wherein the predetermined criteria corresponds to whether the wireless device is compatible with a particular network; and

in response to a determination that the capability report meets the predetermined criteria, denying the connection request, wherein

the connection request is an initial attach request received directly from the wireless device,

the capability report includes a device type of the wireless device, and

the predetermined criteria is that the device type is included in a list of devices that do not support an Enhanced 911 (E-911) service.

2. The method according to claim 1 , wherein the device type includes data indicating a manufacturer and/or a model of the wireless device.

3. The method according to claim 1 , wherein the list of devices is set by a network operator.

4. The method according to claim 1 , wherein the list of devices includes a plurality of Type Allocation Codes (TACs) in the form of a lookup table.

5. The method according to claim 1 , wherein the capability report is included in the connection request.

6. The method according to claim 1 , further comprising:

in response to a determination that the capability report does not meet the predetermined criteria, accepting the connection request.

7. A system for managing device connections in a telecommunications network, the system comprising:

a first access node configured to provide access to a particular network of the telecommunications network; and

at least one electronic processor configured to perform operations including:

receiving a communication from a wireless device, the communication including an initial attach request;

comparing a capability report of the wireless device to a predetermined criteria, wherein the predetermined criteria is based on a compatibility between the wireless device and the particular network; and

in response to a determination that the capability report meets the predetermined criteria, denying the connection request,

wherein the capability report includes a device type of the wireless device, and

wherein the predetermined criteria is that the device type is included in a list of devices that do not support an Enhanced 911 (E-911) service.

8. The system according to claim 7 , wherein the device type includes data indicating a manufacturer and/or a model of the wireless device.

9. The system according to claim 7 , wherein the list of devices is set by a network operator.

10. The system according to claim 7 , wherein the list of devices includes a plurality of Type Allocation Codes (TACs) in the form of a lookup table.

11. The system according to claim 7 , wherein the initial attach request includes the capability report.

12. The system according to claim 7 , the operations further comprising, in response to a determination that the capability report does not meet the predetermined criteria, accepting the connection request.

13. The system according to claim 7 , wherein the communication includes an International Mobile Subscriber Identity (IMSI), an International Mobile Equipment Identity (IMEI), a Mobile Country Code (MCC) of a home PLMN of a (SIM) associated with the wireless device, a Mobile Network Code (MNC) of the home PLMN of the SIM associated with the wireless device, a Mobile Subscription Identification Number (MSIN), a Type Allocation Code (TAC), a Regional Zone Code Identity (RSZI), a Zone Code (ZC), or combinations thereof.

14. A processing node in a telecommunications network, the processing node being configured to perform operations comprising:

receiving an attach request and a capability report from a wireless device; and

in response to a determination that the capability report meets a predetermined criteria, denying the attach request, wherein

the predetermined criteria corresponds to whether the wireless device is compatible with a communication feature of the network,

the capability report identifies a device type of the wireless device, and

the predetermined criteria is based on whether the device type indicates a lack of support for an Enhanced 911 (E-911) service.

15. The processing node according to claim 14 , wherein the device type includes data indicating a manufacturer and/or a model of the wireless device.

16. The processing node according to claim 14 , the operations further comprising determining whether the device type indicates the lack of support for the E-911 service by comparing the device type to a list of compatible devices.

17. The processing node according to claim 16 , wherein the list of compatible devices is set by a network operator.

18. The processing node according to claim 16 , wherein the list of compatible devices is in the form of a lookup table.

19. The processing node according to claim 14 , the operations further comprising, in response to a determination that the capability report does not meet the predetermined criteria, accepting the attach request.

20. The processing node according to claim 14 , wherein the capability report includes an International Mobile Subscriber Identity (IMSI), an International Mobile Equipment Identity (IMEI), a Mobile Country Code (MCC) of a home PLMN of a (SIM) associated with the wireless device, a Mobile Network Code (MNC) of the home PLMN of the SIM associated with the wireless device, a Mobile Subscription Identification Number (MSIN), a Type Allocation Code (TAC), a Regional Zone Code Identity (RSZI), a Zone Code (ZC), or combinations thereof.
