Abstract

A system and method manages call connections between mobile subscribers and an EP-based wireless telecommunications network through a wireless access point. Communications between the mobile subscribers and the IP-based wireless telecommunications network are initiated by a registration request. During the registration request various identifiers (IMSI, MAC address, IP Address, etc.) are communicated to the system. The system is arranged to log the identifiers and associate those identifiers with the entry point (e.g., the wireless access point) into the IP based wireless network. Call connections from the mobile subscribers are monitored for various throughput and call quality based metrics. Call handoffs between the IP-based wireless communications network and the cellular telephony network are managed by the system based on the monitored call quality and throughput metrics on a per-access point basis using the registered identifiers.

Claims

1. A computer-implemented method for ensuring communication quality for a mobile subscriber device (MS) on an IP-based wireless telecommunications network, the method comprising:

monitoring mobile registration requests for communication connections from the mobile subscriber device (MS),

wherein communication connections from the MS are at least in part managed in the IP-based wireless telecommunications network,

wherein the IP-based wireless telecommunications network has an IP-core,

wherein each communication connection is associated with an entry point into the IP-based wireless telecommunications network, and

wherein the entry point is identified by at least one of a Media Access Control (MAC) address or an Internet Protocol (IP) address;

logging, at a network controller of the IP-based wireless telecommunications network, communication connections between the MS and multiple entry points during registration requests placed from the MS to the multiple entry points, including;

a unique identifier of the certain MS locally stored by the certain MS, and

unique identifiers of the multiple entry points;

determining a number of ongoing communication connections that are associated with a specific entry point of the multiple entry points; and

initiating a handoff from the IP-based wireless telecommunications network to a cellular telephony network of at least one ongoing communication connection associated with the specific entry point when the determined number of ongoing communication connections reaches a threshold limit,

such that communication quality for each remaining communication connections in the IP-based wireless telecommunications network is improved.

2. The computer-implemented method of claim 1, wherein the unique identifier of the MS is an International Mobile Subscriber Identifier (IMSI).

3. The computer-implemented method of claim 1, further comprising dynamically adjusting the threshold limit.

4. The computer-implemented method of claim 1,

wherein the specific entry point corresponds to a wireless access point, and

wherein handing off the at least one ongoing communication connection comprises handing off the at least one ongoing communication connection associated with the specific entry point to another access point when the determined number of ongoing communication connections for the specific entry point reaches the threshold limit.

5. A computer system for ensuring communication quality for a mobile subscriber device (MS) on an IP-based wireless telecommunications network, comprising:

a processor and at least one memory, cooperating to function as;

a monitoring unit configured to monitor mobile registration requests for communication connections from the mobile subscriber device (MS),

wherein communication connections from the MS are at least in part managed in the IP-based wireless telecommunications network,

wherein the IP-based wireless telecommunications network has an IP-core,

wherein each communication connection is associated with an entry point into the IP-based wireless telecommunications network, and

wherein the entry point is identified by at least one of a Media Access Control (MAC) address or an Internet Protocol (IP) address;

a logging unit configured to log flail communication connections between the MS and certain entry points during registration requests placed from the certain MS to the certain entry points and based on a unique identifier of the certain MS locally stored by the certain MS and flail unique identifiers of the certain entry points;

a determining unit configured to determine a number of ongoing communication connections that are associated with a specific entry point; and

an initiating unit configured to initiate a handoff, by the IP-based wireless telecommunications network, of at least one ongoing communication connection associated with the specific entry point to a cellular telephony network when the determined number of ongoing communication connections reaches a threshold limit, such that communication quality for each remaining communication connection in the IP-based wireless telecommunications network is improved.

6. The computer system of claim 5, wherein the unique identifier of the MS is an International Mobile Subscriber Identifier (IMSI).

7. The computer system of claim 5, the processor and memory further cooperating to function as an adjusting unit configured to dynamically adjust the threshold limit.

8. The computer system of claim 5,

wherein the specific entry point corresponds to a wireless access point, and

wherein the initiating unit is further configured to hand off the at least one ongoing communication connection associated with the specific entry point to another access point when the determined number of ongoing communication connections for the specific entry point reaches the threshold limit.

9. A non-transitory computer-readable storage medium having stored thereon instructions which when executed by one or more processors perform a method of ensuring communication quality for a mobile subscriber (MS) on an IP-based wireless telecommunications network, the method comprising:

monitoring mobile registration requests for communication connections from the mobile subscriber (MS), wherein communication connections from the MS are at least in part managed in the IP-based wireless telecommunications network,

wherein the IP-based wireless telecommunications network has an IP-core,

wherein each communication connection is associated with an entry point into the IP-based wireless telecommunications network, the entry point being a wireless access point, and

wherein the entry point is identified by at least one of a Media Access Control (MAC) address or an Internet Protocol (IP) address;

logging flail communication connections between the MS and certain entry points during flail registration requests placed from the MS to the certain entry points, including a locally stored unique identifier of the MS and unique identifiers of the certain entry points;

determining a number of ongoing communication connections that are associated with a specific entry point; and

initiating a handoff from the specific entry point to a different wireless access point, by the IP-based wireless telecommunications network, of at least one ongoing communication connection associated with the specific entry point when the determined number of ongoing communication connections reaches a threshold limit.

10. The non-transitory computer-readable storage medium of claim 9, wherein the unique identifier of the certain MS is an International Mobile Subscriber Identifier (IMSI).

11. The non-transitory computer-readable storage medium of claim 9, wherein the method further comprises dynamically adjusting the threshold limit.

12. The non-transitory computer-readable storage medium of claim 9, wherein handing off the at least one ongoing communication connection comprises handing off an additional ongoing communication connection associated with the specific entry point to a cellular telephony network when the determined number of ongoing communication connections reaches the threshold limit.
