Preventing collision of mobile session identifiers in neutral host network
A first identifier of a mobile session is generated for a mobile device accessing a network operating in an unlicensed radio band, wherein at least one part of the first mobile session identifier comprises a decimal format consistent with an identifier recognizable by a network operating in a licensed radio band. The first mobile session identifier is compared to one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network to prevent collision there between.
1. A method, comprising:
generating a first identifier of a mobile session for a mobile device accessing a network operating in an unlicensed radio band, wherein at least one part of the first mobile session identifier comprises a decimal format consistent with an identifier recognizable by a network operating in a licensed radio band; and
comparing the first mobile session identifier to one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network to prevent collision there between;
wherein when the first mobile session identifier is determined to collide with one of the one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network, discarding the first mobile session identifier and re-generating a second mobile session identifier for the mobile device.
2. The method of claim 1 , further comprising repeating the comparing and re-generating steps until a unique mobile session identifier is generated for the mobile device.
3. The method of claim 2 , further comprising storing the unique mobile session identifier in a database.
4. The method of claim 3 , further comprising removing a mobile session identifier from the database when the mobile session terminates.
5. The method of claim 2 , further comprising providing the unique mobile session identifier to a network element in the unlicensed radio band network.
6. The method of claim 1 , wherein the network operating in an unlicensed radio band comprises a Neutral Host Network.
7. The method of claim 1 , wherein the network operating in a licensed radio band comprises a 3GPP Evolved Packet Core network.
8. An apparatus comprising:
a memory; and
a processor operatively coupled to the memory and configured to:
generate a first identifier of a mobile session for a mobile device accessing a network operating in an unlicensed radio band, wherein at least one part of the first mobile session identifier comprises a decimal format consistent with an identifier recognizable by a network operating in a licensed radio band; and
compare the first mobile session identifier to one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network to prevent collision there between;
wherein when the first mobile session identifier is determined to collide with one of the one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network, discarding the first mobile session identifier and re-generating a second mobile session identifier for the mobile device.
9. The apparatus of claim 8 , wherein the processor and memory are further configured to repeat the comparing and re-generating steps until a unique mobile session identifier is generated for the mobile device.
10. The apparatus of claim 9 , wherein the processor and memory are further configured to store the unique mobile session identifier in a database.
11. The apparatus of claim 10 , wherein the processor and memory are further configured to remove a mobile session identifier from the database when the mobile session terminates.
12. The apparatus of claim 9 , wherein the processor and memory are further configured to provide the unique mobile session identifier to a network element in the unlicensed radio band network.
13. The apparatus of claim 8 , wherein the network operating in an unlicensed radio band comprises a Neutral Host Network.
14. The apparatus of claim 8 , wherein the network operating in a licensed radio band comprises a 3GPP Evolved Packet Core network.
15. An article of manufacture comprising a processor-readable non-transitory storage medium having embodied therein executable program code that when executed by the processing device causes the processing device to perform steps of:
generating a first identifier of a mobile session for a mobile device accessing a network operating in an unlicensed radio band, wherein at least one part of the first mobile session identifier comprises a decimal format consistent with an identifier recognizable by a network operating in a licensed radio band; and
comparing the first mobile session identifier to one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network to prevent collision there between;
wherein when the first mobile session identifier is determined to collide with one of the one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network, discarding the first mobile session identifier and re-generating a second mobile session identifier for the mobile device.
16. The article of claim 15 , further comprising repeating the comparing and re-generating steps until a unique mobile session identifier is generated for the mobile device.
17. The article of claim 16 , further comprising storing the unique mobile session identifier in a database.
18. The article of claim 17 , further comprising removing a mobile session identifier from the database when the mobile session terminates.
19. The article of claim 16 , further comprising providing the unique mobile session identifier to a network element in the unlicensed radio band network.
20. The article of claim 15 , wherein the network operating in an unlicensed radio band comprises a Neutral Host Network.
21. The article of claim 15 , wherein the network operating in a licensed radio band comprises a 3GPP Evolved Packet Core network.
22. The method of claim 1 , wherein the decimal format consistent with the identifier recognizable by the network operating in the licensed radio band comprises an International Mobile Subscriber Identity (IMSI) format.
23. The apparatus of claim 8 , wherein the decimal format consistent with the identifier recognizable by the network operating in the licensed radio band comprises an International Mobile Subscriber Identity (IMSI) format.
24. The article of claim 15 , wherein the decimal format consistent with the identifier recognizable by the network operating in the licensed radio band comprises an International Mobile Subscriber Identity (IMSI) format.
