Embodiment 1

[0062] refer to figure 2 , illustrating the paging process of determining a fixed paging carrier for a paging group described in Embodiment 1 of the present invention. During network deployment, a paging carrier set is assigned to the paging group according to the fully configured carrier list at each base station in the paging group. The paging carrier set needs to cover the entire paging group to ensure that each base station supports at least one of them. one.

[0063] For example, if figure 1 As shown, in the paging group PGID xx, the set of carriers supporting base stations A, B, and C may be {C1, C2} or {C2, C3}. If the paging carrier set is defined as {C2, C3} for the paging group during network deployment, each base station needs to send paging messages on at least one of the carriers, and base station B that supports both C2 and C3 can choose to use Send paging messages on one carrier or on both carriers simultaneously. The arrangement of C2 and C3 may be random ...

Embodiment 2

[0081] refer to image 3 , which describes the paging process in the scenario where each base station broadcasts its own PGID and corresponding paging carrier described in Embodiment 2 of the present invention.

[0082] For example, if figure 1 As shown, the set of carriers at base station A in the paging group PGID xx is {C1, C3}, the set of carriers at base station B is {C2, C3, C4}, and the set of carriers at base station C is {C2}. Each base station may select a different carrier for each PGID to which it belongs to carry its paging message. Assume that the paging carrier selected by base station A for PGID xx is C1, the paging carrier selected by base station B for PGID xx is C2, and the paging carrier selected by base station C for PGIDxx is C2.

Embodiment 3

[0103] refer to Figure 4 It shows that the base station described in Embodiment 3 of the present invention only indicates the paging carrier under the current base station for the MS that enters the idle mode at its own, and does not broadcast the paging process of the paging carrier scenario of each PGID.

[0104] like figure 1 As shown, the set of carriers at base station A in the paging group PGID xx is {C1, C3}, the set of carriers at base station B is {C2, C3, C4}, and the set of carriers at base station C is {C2}. Assume that the MS enters the idle mode at base station A, and the paging carrier designated by base station A is C1.

[0105] Figure 4 It is a flow chart of receiving a paging message by an idle mode MS in a multi-carrier wireless communication system according to Embodiment 3 of the present invention, as shown in Figure 4 As shown, including the following steps S402 to S420:

[0106] In step S402, the MS is in a connected state.

[0107] Step S404, th...

Abstract

The invention discloses a paging carrier indicating method and a base station, and the paging carrier indicating method comprises the step of leading the base station to send information of a paging carrier to a terminal, wherein the paging carrier is used for sending a paging message. The paging carrier indicating method and the base station can solve the problem that an MS needs to carry out unnecessary network re-entry due to uncertainty of the paging carrier in an existing wireless communication system, and further reduce the unnecessary network re-entry of the MS.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method for indicating a paging carrier and a base station. Background technique [0002] In order to improve the data transmission rate of the wireless communication system, a multi-carrier technology is proposed. Under the protocol architecture of the multi-carrier wireless communication system, a unified Media Access Control entity (MediaAccess Control, referred to as MAC) controls the physical layer (Physical layer, including multiple channels (channel 1, channel 2, ..., channel N). Abbreviated as PHY). Wherein, each channel may have a different bandwidth, and the bandwidth here may be a continuous or discontinuous frequency band. [0003] In a multi-carrier wireless communication system, for a base station, carriers can be divided into fully configured carriers and partially configured carriers. Wherein, the fully configured carrier refers to a carrier configured with ...
