Communication via dedicated network nodes
View Patent ↗Briefly, in accordance with one or more embodiments, methods to establish and control communication of a dedicated device such as a dedicated user equipment (UE) with dedicated nodes of a network are provided.
1. A mobility management entity (MME) to redirect a dedicated user equipment (UE) from a non-dedicated enhanced Node B (eNB) to a dedicated enhanced Node B (eNB), comprising:
a processor and memory coupled to the processor, wherein instructions in the memory configure the processor to:
receive a Non-Access Stratum (NAS) message from the dedicated UE via the non-dedicated eNB while the dedicated UE is connected to the non-dedicated eNB, wherein the NAS message includes a power saving mode (PSM) information element;
wherein the MME determines whether to redirect the dedicated UE to the dedicated eNB based on the PSM information element in the NAS message; and
send a release command to the non-dedicated eNB in response to the PSM information element in the NAS message, the release command to cause the non-dedicated eNB to send a connection release message to the dedicated UE, wherein the connection release message includes a carrier redirect message to redirect the dedicated UE from the non-dedicated eNB to the dedicated eNB.
2. The mobility management entity as claimed in claim 1 , wherein the NAS message from the dedicated UE is transmitted via a radio resource control (RRC) connection setup.
3. The mobility management entity as claimed in claim 1 , wherein the release command sent to the non-dedicated eNB includes the PSM indication as a cause for the release command.
4. A mobility management entity (MME) to redirect a dedicated user equipment (UE) from a non-dedicated enhanced Node B (eNB) to a dedicated enhanced Node B (eNB), comprising:
means for receiving a Non-Access Stratum (NAS) message from the dedicated UE via the non-dedicated eNB while the dedicated UE is connected to the non-dedicated eNB, wherein the NAS message includes a power saving mode (PSM) information element;
wherein the MME determines whether to redirect the dedicated UE to the dedicated eNB based on the PSM information element in the NAS message; and
means for sending a release command to the non-dedicated eNB in response to the PSM information element in the NAS message, the release command to cause the non-dedicated eNB to send a connection release message to the dedicated UE, wherein the connection release message includes a carrier redirect message to redirect the dedicated UE from the non-dedicated eNB to the dedicated eNB.
5. The mobility management entity as claimed in claim 4 , wherein the NAS message from the dedicated UE is received via a radio resource control (RRC) connection setup.
6. The mobility management entity as claimed in claim 4 , wherein the release command sent to the non-dedicated eNB includes the PSM indication as a cause for the release command.
