Abstract

The invention relates to a method for monitoring the security of an area, a corresponding security monitor device and a wireless access device. The method comprises steps of: determining whether there is at least one first mobile device accessing a wireless access device that serves said area; starting to monitor a breach of security conditions, if there is no at least one first mobile device accessing the wireless access device; and, generating an alarm signal and sending said signal to one of said at least one first mobile device, if the breach of security conditions is detected. With this method, it does not need the host to turn on the security monitoring device every time he leaves home and effectively eliminates the possibility of forgetting to turn on the security monitoring procedure by the user, making the security device more reliable and convenient.

Claims

1-24. -24. (canceled)

25. A method for monitoring the security of an area, comprising:

determining whether there is at least one first mobile device accessing a wireless access device that serves said area;

starting to monitor a breach of security conditions, if there is no at least one first mobile device accessing the wireless access device; and

,

generating an alarm signal and sending said signal to one of said at least one first mobile device, if the breach of security conditions is detected.

26. The security monitoring method according to claim 25, wherein said at least one first mobile device is a host device, and at least one identifier of said at least one first mobile device is stored in a security list.

27. The security monitoring method according to claim 26, wherein the breach of security conditions is monitored by:

receiving a signaling from a second mobile device;

deriving an identifier of said second mobile device from said signaling;

comparing the identifier of said second mobile device with the at least one identifier of said at least one first mobile device in the security list; and

determining that the security conditions have been breached if the identifier of said second mobile device does not match any one of said at least one identifier of said at least one first mobile device in the security list.

28. The security monitoring method according to claim 26, wherein the breach of security conditions is monitored by:

receiving a signaling from a second mobile device;

deriving an identifier of said second mobile device from said signaling;

comparing the identifier of said second mobile device with said at least one identifier of said at least one first mobile device in the security list; and

determining that the security conditions have been breached, if the identifier of said second mobile device does not match any one of said at least one identifier of said at least one first mobile device in the security list and said second mobile device has been accessing the wireless access device for a predetermined time period.

29. The security monitoring method according to claim 27, wherein the identifier of said second mobile device is stored in an access log.

30. The security monitoring method according to claim 27, wherein said at least one identifier of said at least one first mobile device and the identifier of said second mobile device are selected from a group consisting of:

ESN, IMEI, IMSI, LAI, P-TMSI, RAI, TMSI, ESN(DS-41), IMSI(DS-41), and TMSI(DS-41).

31. The security monitoring method according to claim 25, wherein the breach of security conditions is monitored by at least one of an infrared sensor, an acoustic sensor, a temperature sensor or an motion sensor, which is used to detect abnormal condition in the area.

32. A security monitoring device for monitoring the security of an area, comprising:

a wireless access device for providing wireless access in said area for at least one first mobile device, and generating a first command signal when there is no first mobile device accessing said wireless access device; and

a security management device, for receiving the first command signal from said wireless access device, starting to monitor a breach of security conditions in said area, and generating an alarm signal and sending said signal to one of said at least one first mobile device, if the breach of security conditions is detected.

33. A wireless access device, comprising:

a transceiver for providing wireless access in its serving area for at lease one first mobile device;

a security management unit for determining whether there is at least one first mobile device accessing a wireless access device that serves said area, and starting to monitor a breach of security conditions, if there is no at least one first mobile device accessing the wireless access device.

34. The wireless access device according to claim 33, further comprising a memory for storing at least one identifier of said at least one first mobile device in a security list, and wherein said at least one first mobile device is a host device.

35. The wireless access device according to claim 34, wherein the transceiver is further configured to receive a signaling from a second mobile device;

and

the security management unit is further configured to derive an identifier of said second mobile device from said signaling;

compare the identifier of said second mobile device with the at least one identifier of said at least one first mobile device in the security list; and

determine that the security conditions have been breached if the identifier of said second mobile device does not match any one of said at least one identifier of said at least one first mobile device in the security list.

36. The wireless access device according to claim 34, wherein the transceiver is further configured to receive a signaling from a second mobile device;

and

the security management unit is further configured to derive an identifier of said second mobile device from said signaling;

compare the identifier of said second mobile device with said at least one identifier of said at least one first mobile device in the security list; and

determine that the security conditions have been breached, if the identifier of said second mobile device does not match any one of said at least one identifier of said at least one first mobile device in the security list and said second mobile device has been accessing the wireless access device for a predetermined time period.

37. The wireless access device according to claim 35, wherein the memory is further configured to store the identifier of said second mobile device in an access log.

38. The wireless access device according to claim 33, wherein said at least one identifier of said at least one first mobile device and the identifier of said second mobile device are selected from a group consisting of:

ESN, IMEI, IMSI, LAI, P-TMSI, RAI, TMSI, ESN(DS-41), IMSI(DS-41), and TMSI(DS-41).

39. The wireless access device according to claim 33, wherein the wireless access device is a Home Node B device.

40. A home security system comprising a wireless access device according to claim 33.

41. A computer program product comprising computer-readable medium, which comprises:

code for determining whether there is at least one first mobile device accessing a wireless access device that serves said area;

code for starting to detect a breach of security conditions, if there is no at least one first mobile device accessing the wireless access device; and

code for generating an alarm signal and sending said signal to one of said at least one first mobile device, if the breach of security conditions is detected.
