example 1

[0085] Example 1 - Separate Neighbor Association Log and History List

[0086] image 3 An exemplary deployment of a mobile device (in this example user equipment 50 ) and wireless communication network 10 is shown. In this example, cells provided, for example, by macro base stations or small cell base stations are mixed in the vicinity of the user equipment 50 .

[0087] The user equipment 50 is supported by cell 1 (source cell) and only cell 2 is a known neighbor of cell 1 since it is included in the NCL of cell 1 . The other cells, cell 3, cell 4, cell 5, and cell 6, are missed neighbors. In this example, the user of the user equipment 50 is sitting in a cafe and occasionally checks his laptop or smartphone, so the user equipment 50 is mainly in an inactive state (such as a Cell Paging Channel (Cell_PCH) state or an idle state ), where there are occasional bursts of traffic to receive or send some user information. When the user equipment 50 is in active state, the ne...

[0099] Example 2 - Weight Detection

[0100] As mentioned earlier, image 3 An exemplary deployment of user equipment 50 and wireless communication network 10 is shown. In this example, in the vicinity of the user equipment 50 there are mixed cells eg provided by macro base stations or small cell base stations, as mentioned before.

[0101] In this example, detection probability weights are included in neighbor association logs and history lists.

[0102] User equipment 50 starts as image 3 The location shown in , and when in the deactivated state performs the detection aspect of the automatic neighbor association feature, thus detecting cell 3 and cell 4. Since the user is sitting in a cafe, the user equipment 50 will detect cell 3 and cell 4 multiple times. In this example, when the user equipment 50 is supported by the cell 1 (source cell), the user equipment 50 detects the cell 3 and the cell 4 1000 times respectively.

[0103] It should be appreciated that there a...

example 3

[0122] Example 3 - Combined Neighbor Association Log and History List

[0123] In this example, the history list and neighbor association logs are merged into a single table. Using the "early" bit in this table allows the functionality provided by the aforementioned history table to be combined into a single table.

[0124] In this example, user equipment 50 also starts with image 3 The location shown in , as mentioned before, and the user equipment 50 detects cell 3 and cell 4 .

[0125] The neighbor association / history log can only store 3 entries in this example, and it is shown in Table 9:

[0126]

[0127] Table 9: Combined Neighbor Association / History Logs After Cell 3 and Cell 4 Detection

[0128] The user equipment 50 then enters the active state and uploads the neighbor association log. User equipment 50 then sets the "earlier" bit to true for entries 1 and 2, resulting in a neighbor association / history log as in Table 10.

Abstract

A mobile device operable to perform automatic neighbour relation functions in a wireless telecommunications network, a radio network controller, methods and a computer program product are disclosed. The mobile device is operable to perform automatic neighbour relation functions in a wireless telecommunications network in which neighbour relations derived by the mobile device are provided to a network node of the wireless telecommunications network and comprises: measurement logic operable, in an automatic neighbour relation mode, to measure characteristics of a neighbouring cell; and determination logic operable to determine, from the characteristics and from an indication of previously provided neighbour relations, whether a neighbour relation based on the characteristics has been provided previously to the network node and, if not, to generate a new neighbour relation to be provided to the network node. Hence, only neighbour relations which are not indicated as having been provided previously need be generated. Accordingly, no neighbour relation may be generated when an indication is provided that that neighbour relation has already been provided. This avoids transmitting redundant information, which reduces traffic in the network and reduces the unnecessary use of resources to transmit and process such duplicated information. This reduces the load in the network and in the mobile device. Furthermore, the power consumption of the mobile device may be reduced as a consequence.

Description

technical field [0001] The present invention relates to a mobile device adapted to perform automatic neighbor association functionality in a wireless communication network, a wireless network controller, methods and a computer program product. Background technique [0002] Wireless communication systems are known. In a cellular system, radio coverage is provided by areas called cells. Base stations are placed in each cell to provide wireless coverage. Each base station can support several cells. Conventional base stations provide coverage over relatively large geographic areas, and cells are often referred to as macro cells. It is possible to provide smaller sized cells within one macrocell. Such smaller sized cells are sometimes referred to as microcells, pico cells or femto cells. One way to establish a small cell is to provide a small cell base station, which provides relatively limited coverage within the coverage area of ​​a macro cell. The transmission power of t...
