Embodiment 1

[0051] In this embodiment, a multi-frequency cell includes one primary frequency point and one or more secondary frequency points. The main frequency point will send a broadcast message in the multi-frequency point cell. In the broadcast message, the PRACH resources of multiple frequency points are mapped to the same set of ASC. At the same time, each frequency point and its respective PRACH resource establish a mapping relationship. The PRACH resource The schematic diagram of the mapping relationship with ASC is as follows image 3 shown. After the UE is turned on in the multi-frequency cell, it reads the broadcast message from the main frequency and obtains the ASC. After the UE obtains the ASC during access initialization, it obtains the corresponding PRACH resource information, and then selects a suitable frequency point for access according to certain rules.

[0052] Specifically, in the application scenario of this embodiment, the terminal access method in the multi-fr...

Embodiment 2

[0072] In this embodiment, a multi-frequency cell includes one primary frequency point and one or more secondary frequency points. Taking the cell as an example with two frequency points including one main frequency point and one auxiliary frequency point, the main frequency point will send a broadcast message in the multi-frequency point cell. In the broadcast message, the PRACH resources of the two frequency points are respectively mapped To two sets of ASCs, the mapping relationship between the PRACH resources and ASCs is as follows Figure 5 shown. After the UE is turned on in the multi-frequency cell, it reads the broadcast message from the primary frequency and obtains the ASC of the UE at the primary frequency and the ASC of the secondary frequency. After the UE acquires the above two ASCs during access initialization, it selects a suitable frequency point for access according to certain rules.

[0073] Specifically, in the application scenario of this embodiment, the...

Embodiment 3

[0088] This embodiment provides a multi-frequency point system, such as Figure 7 As shown, it includes: a terminal device 10 and a network side device 20 , the network side device 20 establishes a mapping relationship between PRACH resource information of multiple frequency points and an ASC, and sends the mapping relationship to the terminal device 10 . The terminal device 10 acquires PRACH resource information of multiple frequency points on the network side device 20, and selects a frequency point for access according to the PRACH resource information of multiple frequency points.

Abstract

The embodiment of the invention discloses a method, a system and equipment for accessing a terminal in a multiple-frequency point system. The method comprises the following steps: obtaining physical random access channel (PRACH) resource information of a plurality of frequency points at a network side; and selecting a frequency point to access according to the PRACH resource information of the frequency points. By adopting the embodiment of the invention, the PRACH resource information of the frequency points at the network side is obtained by the terminal, and the frequency point is selectedto access according to the PRACH resource information of the multiple frequency points so that the terminal in the multiple-frequency point system can select the proper frequency point to access, thesuccess ratio of terminal access is improved, the access load of the various frequency points is balanced, and the network operation efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a terminal access method, system and equipment in a multi-frequency point system. Background technique [0002] HSPA (High Speed ​​Packet Access, High Speed ​​Packet Access) technology is a new technology introduced by 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project). HSPA technology can also be applied to WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) FDD (Frequency Division Duplex, frequency division duplex), UTRA (Universal Terrestrial Radio Access, universal terrestrial wireless access) TDD (Time Division Duplex, Time Division Duplex) and TD-SCDMA (Time Division-Synchronization CDMA, time division-synchronous code division multiple access) three different transmission modes. Usually HSPA is carried on a single frequency point. In order to further increase the data transmission rate of t...
