Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0036] figure 2 The paging method for avoiding frequency confusion of the present invention includes the following steps:

[0037] In step 201, the terminal reports to the network at least one original Bandsubclass supported by the original Bandclass and at least one new Bandsubclass supported during session negotiation.

[0038] image 3 Shown is a schematic diagram of the relationship among frequency bands, atomic frequency bands, and new sub-frequency bands after the sub-frequency bands are newly defined. by image 3For example, during session negotiation, the terminal needs to report Bandsubclass0 and Bandsubclass4 supported under Bandclass0, indicating that the terminal has the ability to support the above freque...

Abstract

The invention discloses a paging method and device capable of avoiding frequency aliasing. A terminal reports at least one original Band subclass supported by a Band class and at least one supported new Band subclass to the network during conversation negotiation. The network broadcasts a network channel table, and the network channel table carries the Band class, the Band subclass and channel series numbers. After receiving the network channel table, the terminal judges whether the Band subclass supported by the Band class and the channel series number contained by the Band subclass are completely identical with the broadcast, and determines whether the frequency point participates in HASH calculation according to the judgment result, thereby enabling the HASH result of the terminal to be consistent with the HASH result of the network and carrying out paging correctly. The paging method and device capable of avoiding frequency aliasing can carry out paging to the terminal correctly when a new frequency is added.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a paging method and device for avoiding frequency confusion. Background technique [0002] figure 1 Shows the relationship among frequency bands, frequency bands (Bandclass, BC), sub-bands (Bandsubclass), and frequency points. [0003] The frequency band can be understood as a frequency range, such as from 824~844MHz. [0004] The frequency band specifically refers to the division and definition of a certain frequency band by international standard organizations (such as 3GPP and 3GPP2). For example, the frequency of 824~839MHz in 824~844MHz is defined as Bandclass0. [0005] The sub-band is to divide the frequency band into multiple sub-bands in Bandclass, for example, 824~835MHz in 824~839MHz is called Bandsubclass0. In this way, it is convenient for each operator to use the frequency flexibly according to the frequency obtained by itself. [0006] The frequency point re...
