The method includes receiving, by a network device in a wireless access network and from a wireless device, a first request for a bootstrap server identifier. The method also includes providing, to the wireless device, a response including an address for a carrier-specific bootstrap server device. The method also includes receiving, by the carrier-specific bootstrap server device, a request for management server connection information. The request is submitted by the wireless device using the bootstrap server identifier. The method further includes assigning, by the carrier-specific bootstrap server device, the wireless device to a management server of a group of management servers and sending connection information for the management server to the wireless device. ## Claims ### Claim 1 A method, comprising: receiving, by a network device in a wireless access network and from a wireless device, a first request for a bootstrap server identifier; providing, by the network device and to the wireless device, a response to the first request, the response including an address for a carrier-specific bootstrap server device; receiving, by the carrier-specific bootstrap server device, a second request, from the wireless device, for management server connection information, wherein the second request uses the bootstrap server identifier; assigning, by the carrier-specific bootstrap server device, the wireless device to a management server of a group of management servers; sending, by the carrier-specific bootstrap server device and to the wireless device, connection information for the management server, wherein the connection information comprises a first security key for use by the wireless device; receiving, by the management server and from the wireless device, a registration request for machine-to-machine management, the registration request including the first security key; requesting, by the management server and from the carrier-specific bootstrap server device, a second security key for the wireless device; and validating the registration request based on the first security key and the second security key. ### Claim 2 (depends on 1) The method of claim 1, wherein receiving the first request for the bootstrap server identifier includes: receiving the first request for the bootstrap server identifier within an attach request for the wireless access network. ### Claim 3 (depends on 2) The method of claim 2, wherein providing the response to the first request includes: providing the response to the first request within a Protocol Configuration Option (PCO) message. ### Claim 4 (depends on 3) The method of claim 3, wherein the PCO message includes a container identifier field for the bootstrap server identifier. ### Claim 5 (depends on 1) The method of claim 1, wherein the response includes a carrier-specific uniform resource locator (URL) for the carrier-specific bootstrap server device. ### Claim 6 (depends on 1) The method of claim 1, wherein the carrier-specific bootstrap server device is a bootstrap server for a lightweight machine-to-machine device management system. ### Claim 7 (depends on 1) The method of claim 1, further comprising: verifying, after receiving the second request, a user profile for the wireless device. ### Claim 8 (depends on 1) The method of claim 1, wherein sending the connection information for the management server further comprises: selecting the management server from a group of available management servers based on a load-balancing criteria. ### Claim 9 (depends on 1) The method of claim 1, wherein the first request is provided from the wireless device in a format that is not specific to a particular network carrier. ### Claim 10 (depends on 1) The method of claim 1, wherein sending the connection information for the management server further comprises generating the first security key. ### Claim 11 A system, comprising: a network device for a wireless access network, the network device including a first memory and a first processor to execute instructions in the first memory to: receive, from a wireless device, a first request for a bootstrap server identifier, and provide, to the wireless device, a response to the first request, the response including an address for a carrier-specific bootstrap server device; the carrier-specific bootstrap server device including a second memory and a second processor to execute instructions in the second memory to: receive a second request, from the wireless device, for management server connection information, wherein the second request uses the bootstrap server identifier; assign the wireless device to a management server device of a group of management servers; send to the wireless device connection information for the assigned management server, wherein the connection information comprises a first security key for use by the wireless device; and the management server device including a third memory and a third processor to execute instructions in the third memory to: receiving, from the wireless device, a registration request for machine-to-machine management, the registration request including the first security key; request, from the carrier-specific bootstrap server device, a second security key for the wireless device; and validate the registration request based on the first security key and the second security key. ### Claim 12 (depends on 11) The system of claim 11, wherein the wireless device is configured for machine-to-machine communications. ### Claim 13 (depends on 11) The system of claim 11, wherein the first request for the bootstrap server identifier is included within an attach request for the wireless access network. ### Claim 14 (depends on 11) The system of claim 11, wherein the response to the first request in included within a Protocol Configuration Option (PCO) message. ### Claim 15 (depends on 14) The system of claim 14, wherein the PCO message includes a designated container identifier field for the bootstrap server identifier. ### Claim 16 (depends on 11) The system of claim 11, wherein the response includes a uniform resource locator (URL) for the carrier-specific bootstrap server device. ### Claim 17 A non-transitory computer-readable medium storing instructions executable by a computational device to: receive, from a wireless device, a first request for a bootstrap server identifier; provide, to the wireless device, a response to the first request, the response including an address for a carrier-specific bootstrap server device; receive a second request, from the wireless device, for management server connection information, wherein the second request uses the bootstrap server identifier; assign the wireless device to a management server of a group of management servers; send, to the wireless device, connection information for the management server, wherein the connection information comprises a first security key for use by the wireless device; receive, from the wireless device, a registration request for machine-to-machine management, the registration request including the first security key; request, from the carrier-specific bootstrap server device, a second security key for the wireless device; and validate the registration request based on the first security key and the second security key. ### Claim 18 (depends on 17) The non-transitory computer-readable medium of claim 17, further comprising instructions to: extract the first request from an attach request for a wireless access network associates with the wireless device. ### Claim 19 (depends on 17) The non-transitory computer-readable medium of claim 17, further comprising instructions to: assemble a Protocol Configuration Option (PCO) message including the response. ### Claim 20 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the response includes a uniform resource locator (URL) for the carrier-specific bootstrap server device.
