Abstract
Aspects of the subject disclosure may include, for example, determining, for a network node, one or more neighbor network nodes relative to the network node; determining, for each of the one or more neighbor network nodes, whether support is provided for a particular type of end-user device; and generating, for the network node, a neighbor cell relation table, wherein the neighbor cell relation table includes the one or more neighbor network nodes, and wherein the neighbor cell relation table further includes for at least one of the neighbor network nodes an indication that support is provided for the particular type of end-user device. Other embodiments are disclosed.
Claims20
A method, comprising:
- sending to a source node of a wireless network, by a processing system of an end-user device including a processor, a handover request, wherein the end-user device is a reduced capability (RedCap) end-user device that conforms to a 3GPP 38.300 V17.5.0 Technical Specification or later standard, and wherein the handover request includes at least one target node to which the end-user device is requesting being handed over;
- determining, by the processing system, that the wireless network has not accepted the handover request, wherein the determining comprises determining whether the wireless network has sent to the end-user device a rejection code in response to the handover request;
- responsive to the wireless network not having sent to the end-user device a rejection code in response to the handover request, determining, by the processing system, a number of times x to retry the handover, wherein x is an integer between 0 and 10;
- attempting, by the processing system, the handover for a maximum of x number of times;
- and
- responsive to the handover not being successful after the x number of attempts, aborting the handover attempts and reselecting, by the processing system, a Long-Term Evolution (LTE) base station to ensure service continuity.
A device, comprising:
- a processing system of an end-user device including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- sending to a source node of a wireless network a handover request, wherein the end-user device is a reduced capability (RedCap) end-user device that conforms to a 3GPP 38.300 V17.5.0 Technical Specification or later standard, and wherein the handover request includes at least one target node to which the end-user device is requesting being handed over;
- determining that the wireless network has not accepted the handover request, wherein the determining comprises determining whether the wireless network has sent to the end-user device a rejection code in response to the handover request;
- responsive to the wireless network not having sent to the end-user device a rejection code in response to the handover request, determining, a number of times x to retry the handover, wherein x is an integer between 0 and 10;
- attempting the handover for a maximum of x number of times;
- and
- responsive to the handover not being successful after the x number of attempts, aborting the handover attempts and reselecting a Long-Term Evolution (LTE) base station to ensure service continuity.
A non-transitory machine-readable medium comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- sending to a source node of a wireless network, by a processing system of an end-user device including a processor, a handover request, wherein the end-user device is a reduced capability (RedCap) end-user device that conforms to a 3GPP 38.300 V17.5.0 Technical Specification or later standard, and wherein the handover request includes at least one target node to which the end-user device is requesting being handed over;
- determining that the wireless network has not accepted the handover request, wherein the determining comprises determining whether the wireless network has sent to the end-user device a rejection code in response to the handover request;
- responsive to the wireless network not having sent to the end-user device a rejection code in response to the handover request, determining, a number of times x to retry the handover, wherein x is an integer between 0 and 10;
- attempting the handover for a maximum of x number of times;
- and
- responsive to the handover not being successful after the x number of attempts, aborting the handover attempts and reselecting a Long-Term Evolution (LTE) base station to ensure service continuity.
