Problems solved by technology

However, if the terminal receives a system message from the femto BS in low duty mode, it will cause location update again, so that there will be non-stop location update operations, causing unnecessary loss
In addition, if the terminal fails to receive the system message, it will remain active until it receives the system message, resulting in unnecessary energy consumption

example 1

[0044] Example 1, Femto BS usage method to adjust a pair of BCH.

[0045] When Femto BS finds that there are no terminals within its jurisdiction, or all terminals are in idle mode, it enters low duty mode. At this time, Femto BS needs to judge under which circumstances it enters idle mode. If there is no terminal, you don’t need to adjust your own BCH. If the terminal under your jurisdiction is in idle mode, you need to adjust the PBCH and SBCH of the Femto BS. As shown in Figure 3, the adjustment method is as follows: According to the paging cycle , paging offset, paging interval length and other parameters to adjust the starting position of PBCH and SBCH, so that the adjusted starting position of PBCH and SBCH is the same as the starting position of terminal paging listening interval, and after adjustment The cycle of the SBCH and the cycle of the PBCH are integer fractions of the paging cycle. For example, on the base station side, the cycle of the PBCH is one-eighth of th...

example 2

[0046] In Example 2, the Femto BS uses the second method to adjust the BCH.

[0047] When Femto BS finds that there are no terminals within its jurisdiction, or all terminals are in idle mode, it enters low duty mode. At this time, Femto BS needs to judge under which circumstances it enters idle mode. If there is no terminal, you don’t need to adjust your own BCH. If the terminal under your jurisdiction is in idle mode, you need to adjust the PBCH and SBCH of the Femto BS. The adjustment method is as follows: set the paging unavailable interval of the terminal to P1, and the terminal The paging Listeninginterval is P2, the interval between PBCH and terminal paging offset is k, then the time interval m of PBCH satisfies the following relationship:

[0048] Ceil((P1-K) / m)*m<(P1+P2-k); wherein, P1, P2, K and M are all integers in superframe units.

[0049] After the above processing, a table about m can be obtained within the allowable range of m. When the Femto BS needs to adju...

Abstract

The invention discloses a method for setting the period of a broadcast channel, which is used for setting the period of the broadcast channel of a femto base station at low power consumption mode. In the method, the femto base station sets the period of the broadcast channel according to the parameters of a terminal in an idle mode within the control range. Due to the technical scheme of the invention, frequent location update is avoided when the broadcast of the femto base station is not received by the terminal in the idle mode, and the unnecessary power waste of the terminal is reduced.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for setting a broadcast channel period. Background technique [0002] In a wireless communication system, a base station (Base Station, BS for short) refers to a device that provides services for a terminal, and the BS communicates with the terminal through the uplink and downlink. The uplink (reverse) link refers to the direction from the terminal to the base station. Also, a plurality of terminals may simultaneously transmit data to the BS through an uplink, and may simultaneously receive data from the BS through a downlink. [0003] In related technologies, the quality of wireless coverage in a mobile network is the key to affecting users' enjoyment of high-speed data, voice, and video services. In order to realize the seamless coverage of the wireless network, it is necessary to focus on solving the problem of wireless coverage in indoor and hotspot a...
