Apparatuses, systems, and methods for paging enhancements for low complexity user equipment
Embodiments described herein relate generally to techniques for paging in a wireless network. In some embodiments, a mobility management entity (MME) may determine a user equipment (UE) is associated with a predetermined category and adjust paging mechanisms based on said determination. Other embodiments may be described and claimed.
1. One or more non-transitory, computer-readable media having instructions that, when executed, cause an access node to:
determine that a user equipment (UE) is a category-0 UE;
generate, by the access node for sending to a mobility management entity (MME), a message that includes:
an information element (IE) with a first category indicator that is to indicate that the UE is a category-0 UE and a service indicator to provide information related to procedures to be used when paging the UE, and
a radio capability structure, which is separate from the IE and includes (i) information about radio capabilities of the UE, and (ii) a second category indicator to indicate that the UE is a category-0 UE; and
transmit the message to the MME.
2. The one or more non-transitory, computer-readable media of claim 1 , wherein the instructions, when executed, further cause the access node to:
transmit the IE to the MME in an S1-application protocol (AP) message.
3. The one or more non-transitory, computer-readable media of claim 1 , wherein the instructions, when executed, further cause the access node to:
process a random access channel (RACH) or a radio resource control (RRC) message to determine the UE is associated with a low-complexity category of UEs.
4. The one or more non-transitory, computer-readable media of claim 1 , wherein the service indicator is to provide information related to coverage enhancement procedures to be used when paging the UE.
5. The one or more non-transitory, computer-readable media of claim 1 , wherein the instructions further cause the access node to:
decode an S1-AP paging message received from the MME, the S1-AP paging message including the IE to indicate that the UE is a category-0 UE.
6. An apparatus to be employed in an access node, the apparatus comprising:
processing circuitry; and
one or more non-transitory, computer-readable media comprising instructions that, upon execution of the instructions by the processing circuitry, are to cause the access node to:
determine that a user equipment (UE) is a category-0 UE;
generate, by the access node for sending to a mobility management entity (MME),
a message that includes:
an information element (IE) with a first category indicator that is to indicate that the UE is a category-0 UE and a service indicator to provide information related to procedures to be used when paging the UE, and
a radio capability structure, which is separate from the IE and includes (i) information about radio capabilities of the UE, and (ii) a second category indicator to indicate that the UE is a category-0a UE; and
transmit the message to the MME.
7. The apparatus of claim 6 , wherein the access node further comprises an Ethernet interface to transmit the IE to the MME.
8. The apparatus of claim 6 , wherein the instructions, when executed, are further to cause the access node to transmit the IE to the MME in an S1-application protocol (AP) message.
9. The apparatus of claim 6 , wherein the instructions, when executed, are further to cause the access node to process a random access channel (RACH) or a radio resource control (RRC) message to determine the UE is associated with a low-complexity category of UEs.
10. The apparatus of claim 6 , wherein the service indicator is to provide information related to coverage enhancement procedures to be used when paging the UE.
11. The apparatus of claim 6 , wherein the instructions, when executed, are further to cause the access node to decode an S1-AP paging message received from the MME, the S1-AP paging message including the IE to indicate that the UE is a category-0 UE.
12. A method comprising:
processing, by a mobility management entity (MME), a message to determine a first information element (IE) that includes a first category indicator to indicate that a user equipment (UE) is a category-0 UE, and a service indicator to provide information related to procedures to be used when paging the UE; and
processing, by the MME, the message to determine a second IE that is a radio capability structure, where the first IE is separate from the second IE and where the second IE includes a second category indicator to indicate that the UE is a category-0 UE.
13. The method of claim 12 , wherein the service indicator is to provide information related to coverage enhancement procedures to be used when paging the UE.
14. The method of claim 12 , further comprising storing, by the MME, the radio capability structure without accessing the second category indicator included in the radio capability structure.
15. The method of claim 12 , wherein the message processed by the MME includes an S1-AP message received from an access node.
16. An apparatus to be employed in mobility management entity (MME), the apparatus comprising:
first circuitry to process a message to determine a first information element (IE) that includes a first category indicator to indicate that a user equipment (UE) is a category-0 UE, and a service indicator to provide information related to procedures to be used when paging the UE; and
second circuitry to process the message to determine a second information element (IE) that is a radio capability structure, wherein the second IE is separate from the first IE and wherein the second IE includes a second category indicator to indicate that the UE is a category-0 UE.
17. The apparatus of claim 16 , further comprising processing circuitry to store the radio capability structure without accessing the second category indicator included in the radio capability structure.
18. The apparatus of claim 16 , wherein the service indicator is to provide information related to coverage enhancement procedures to be used when paging the UE.
19. The apparatus of claim 16 , wherein the message processed by the MME includes an S1-AP message received from an access node.
20. The apparatus of claim 16 , wherein the first circuitry and the second circuitry are elements of communication circuitry of the MME.
21. One or more non-transitory, computer-readable media having instructions that, when executed, cause a mobility management entity (MME) to:
process a message to determine a first information element (IE) that includes a first category indicator to indicate that a user equipment (UE) is a category-0 UE, and a service indicator to provide information related to procedures to be used when paging the UE; and
process the message to determine a second IE that is a radio capability structure, where the first IE is separate from the second IE and where the second IE includes a second category indicator to indicate that the UE is a category-0 UE.
22. The one or more non-transitory, computer-readable media of claim 21 , wherein the service indicator is to provide information related to coverage enhancement procedures to be used when paging the UE.
23. The one or more non-transitory, computer-readable media of claim 21 , wherein the instructions further cause the MME to store the radio capability structure without accessing the second category indicator included in the radio capability structure.
