Abstract

This disclosure pertains to a method in a network node, a method in user equipment, a network node and user equipment in a wireless communications network. More particularly, there is provided methods and platforms for network based control of report messages comprising logged measurements in a wireless communications network. In accordance with some example embodiments, a UE (30) that has stored logged data i.e. logged measurements that are bigger than a single transmission packet, i.e. report message, segments the logged measurements and sends only a portion of the logged measurements that fits into a single report message. The UE (30) also indicates to a network node (28) that additional logged measurements exist at the UE buffer (44).

Claims

1. A computer program product comprising a non-transient machine-readable medium carrying instructions which, when executed by a processor, cause the processor to:

send a request to a user equipment, UE, to start transmitting logged measurements in a report message;

receive the report message comprising logged measurements;

determine if the received report message comprises an indicator of additional logged measurements not yet transmitted; and

if so,

decide if the additional logged measurements are to be requested.

2. The computer program product according to claim 1, wherein the processor is further operable to receive, from the UE, an indication of existents of logged measurements that are available.

3. The computer program product according to claim 1, wherein the logged measurements comprises one or more of the following:

measurement time stamps for each performed measurement;

UE buffer state condition;

positioning information of UE;

periodically measured downlink pilot signal strength;

serving cell conditions;

transmit power headroom conditions;

paging channel failure(s); and

broadcast channel failure(s).

4. The computer program product according to claim 1, wherein the report message is received directly from the UE or via another network node.

5. The computer program product according to claim 1, wherein the deciding is based on one or more of the following:

interference level experienced in a cell;

radio condition measurements experienced in a cell;

available radio resource;

network node capacity;

UE buffer state condition etc.

6. The computer program product according to claim 1, wherein the determining comprises determining if the indicator indicates that there is logged measurements in a buffer of the UE that do, or do not, fit in a single subsequent report message.

7. The computer program product according to claim 6, wherein the deciding comprises deciding to request all the logged measurements in the buffer of the UE in one subsequent request.

8. The computer program product according to claim 1, wherein the processor is operable to receive a previously sent report message from another network node(s), automatically or upon request.

9. The computer program product according to claim 1, wherein the sending of a request is initiated by a UE handover procedure from another network node to the network node.

10. The computer program product according to claim 9, wherein the processor is operable to receive receiving a network node message from the other network node comprising UE specific information.

11. The computer program product according to claim 10, wherein the UE specific information comprises the indicator of additional logged measurements not yet transmitted.

12. A computer program product comprising a non-transient machine-readable medium carrying instructions which, when executed by a processor to:

receive a request from a network node to start transmitting logged measurements in a report message;

determine if the logged measurements fit in the report message; and

if not, including in the report message an indicator of additional logged measurements not yet transmitted; and

,

transmit the report message, comprising the indicator, to the network node as a response to the request.

13. The computer program product according to claim 12, wherein the including comprises including a reporting time stamp in the report message.

14. The computer program product according to claim 12, wherein the logged measurements that are transmitted to the network node are further deleted from the buffer of the UE.

15. The computer program product according to claim 12, wherein the logged measurements that are oldest in the buffer are reported first.
