Abstract

The present invention discloses a method and a user equipment for processing frequency information. The method for processing frequency information includes: receiving a measurement control message sent from network device, where the measurement control message contains frequency information for inter-frequency measurement without compressed mode; and clearing stored frequency information for inter-frequency measurement without compressed mode if the type of frequency information for inter-frequency measurement without compressed mode that is contained in the measurement control message is different from the type of the stored frequency information for inter-frequency measurement without compressed mode. The technical solutions disclosed in the present invention avoid a problem of measurement failure when a UE performs measurement without compressed mode on an adjacent frequency.

Claims

1. A method for processing frequency information, comprising:

receiving a first measurement control message sent from a network device; and

clearing stored frequency information for inter-frequency measurement without compressed mode if the first measurement control message does not contain frequency information for inter-frequency measurement without compressed mode;

wherein, before the receiving the first measurement control message from the network device, the method further comprises;

receiving a second measurement control message from the network device, wherein the second measurement control message includes the frequency information for inter-frequency measurement without compressed mode; and

storing the frequency information for inter-frequency measurement without compressed mode;

wherein the frequency information in the second measurement control message is an inter-frequency neighboring cell list and an adjacent frequency index for inter-frequency measurement without compressed mode in the inter-frequency neighboring cell list;

if the first measurement control message includes the adjacent frequency index and does not include a newly created inter-frequency neighboring cell list, the method further comprises;

reserving the stored frequency information for inter-frequency measurement without compressed mode; and

if the first measurement control message includes both the adjacent frequency index and the newly created inter-frequency neighboring cell list, the method further comprises;

updating the stored frequency information for inter-frequency measurement without compressed mode according to the adjacent frequency index and the newly created inter-frequency neighboring cell list that are included in the first measurement control message.

2. The method according to claim 1, wherein the frequency information in the second measurement control message is first frequency information indicated by the network device;

if the first measurement control message includes second frequency information and the second frequency information is the same as the first frequency information, or if the first measurement control message includes fields indicating the continuous use of the first frequency information, the method further comprises;

reserving the stored frequency information for inter-frequency measurement without compressed mode; and

if the first measurement control message includes the second frequency information and the second frequency information is different from the first frequency information, the method further comprises;

updating the stored frequency information for inter-frequency measurement without compressed mode to the second frequency information.

3. A user equipment, comprising:

a receiver, configured to receive a first measurement control message sent from a network device;

wherein the receiver is further configured to receive a second measurement control message from the network device before the reception of the first measurement control message and wherein the second measurement control message includes frequency information for inter-frequency measurement without compressed mode; and

the user equipment further comprises;

a memory, configured to store the frequency information for inter-frequency measurement without compressed mode; and

a processor, configured to clear stored frequency information for inter-frequency measurement without compressed mode if the first measurement control message does not contain frequency information for inter-frequency measurement without compressed mode;

wherein the frequency information in the second measurement control message is an inter-frequency neighboring cell list and an adjacent frequency index for inter-frequency measurement without compressed mode in the inter-frequency neighboring cell list; and

the processor is further configured to reserve the stored frequency information for inter-frequency measurement without compressed mode if the first measurement control message includes the adjacent frequency index and does not contain a newly created inter-frequency neighboring cell list; and

update the stored frequency information for inter-frequency measurement without compressed mode according to the adjacent frequency index and the newly created inter-frequency neighboring cell list that are included in the first measurement control message if the first measurement control message includes both the adjacent frequency index and the newly created inter-frequency neighboring cell list.

4. The user equipment according to claim 3, wherein the frequency information in the second measurement control message is first frequency information indicated by the network device;

and

the processor is further configured to reserve the stored frequency information for inter-frequency measurement without compressed mode if the first measurement control message includes second frequency information and the second frequency information is the same as the first frequency information, or if the first measurement control message includes fields indicating the continuous use of the first frequency information; and

update the stored frequency information for inter-frequency measurement without compressed mode to the second frequency information if the first measurement control message includes the second frequency information and the second frequency information is different from the first frequency information.
