Session creation for wireless device
A mobility management entity (MME) receives, from a wireless device, an attach request message indicating that the wireless device supports signaling for a first number of bearers, wherein the attach request message comprises an international mobile subscriber identity (IMSI). The MME selects a network gateway from a plurality of network gateways based on a second number of bearers supported by the network gateway. The MME sends, to the network gateway, a create session request message for creating a session for the wireless device. The MME receives, from the network gateway, a create session response message confirming creation of the session.
1. A method comprising:
receiving, by a mobility management entity (MME) from a wireless device, an attach request message indicating that the wireless device supports signaling for a first number of bearers, wherein the attach request message comprises an international mobile subscriber identity (IMSI);
selecting, by the MME, a network gateway from a plurality of network gateways based on a second number of bearers supported by the network gateway;
sending, by the MME to the network gateway, a create session request message for creating a session for the wireless device; and
receiving, by the MME from the network gateway, a create session response message confirming creation of the session.
2. The method of claim 1 , wherein the first number of bearers is fifteen.
3. The method of claim 1 , wherein the attach request message comprises one or more of:
an old globally unique temporary identifier (GUTI);
an old GUTI type;
an additional GUTI;
a tracking area identifier (TAI) of a last visited tracking area; and
an attach type.
4. The method of claim 1 , wherein the attach request message is received via a base station.
5. The method of claim 1 , wherein the session is an internet protocol connectivity access network (IP-CAN) session.
6. The method of claim 1 , further comprising receiving, by the MME from the plurality of network gateways, a plurality of messages.
7. The method of claim 6 , wherein each message of the plurality of messages comprises an information element indicating a capability of a supported number of bearers for each of the plurality of network gateways.
8. A mobility management entity (MME) comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the MME to:
receive, from a wireless device, an attach request message indicating that the wireless device supports signaling for a first number of bearers, wherein the attach request message comprises an international mobile subscriber identity (IMSI);
select a network gateway from a plurality of network gateways based on a second number of bearers supported by the network gateway;
send, to the network gateway, a create session request message for creating a session for the wireless device; and
receive, from the network gateway, a create session response message confirming creation of the session.
9. The MME of claim 8 , wherein the first number of bearers is fifteen.
10. The MME of claim 8 , wherein the attach request message comprises one or more of:
an old globally unique temporary identifier (GUTI);
an old GUTI type;
an additional GUTI;
a tracking area identifier (TAI) of a last visited tracking area; and
an attach type.
11. The MME of claim 8 , wherein the attach request message is received via a base station.
12. The MME of claim 8 , wherein the session is an internet protocol connectivity access network (IP-CAN) session.
13. The MME of claim 8 , wherein the instructions further cause the MME to receive, from the plurality of network gateways, a plurality of messages.
14. The MME of claim 13 , wherein each message of the plurality of messages comprises an information element indicating a capability of a supported number of bearers for each of the plurality of network gateways.
15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a mobility management entity (MME), cause the MME to:
receive, from a wireless device, an attach request message indicating that the wireless device supports signaling for a first number of bearers, wherein the attach request message comprises an international mobile subscriber identity (IMSI);
select a network gateway from a plurality of network gateways based on a second number of bearers supported by the network gateway;
send, to the network gateway, a create session request message for creating a session for the wireless device; and
receive, from the network gateway, a create session response message confirming creation of the session.
16. The non-transitory computer-readable medium of claim 15 , wherein the first number of bearers is fifteen.
17. The non-transitory computer-readable medium of claim 15 , wherein the attach request message comprises one or more of:
an old globally unique temporary identifier (GUTI);
an old GUTI type;
an additional GUTI;
a tracking area identifier (TAI) of a last visited tracking area; and
an attach type.
18. The non-transitory computer-readable medium of claim 15 , wherein the attach request message is received via a base station.
19. The non-transitory computer-readable medium of claim 15 , wherein the session is an internet protocol connectivity access network (IP-CAN) session.
20. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the MME to receive, from the plurality of network gateways, a plurality of messages.
