Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present application.

[0024] The term "comprises" and any variations thereof in the specification and claims of this application are intended to cover a non-exclusive inclusion, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the steps or units expressly recited, but may include other steps or units not expressly recited or inherent to those processes, methods, products, or apparatus. Also, "and / or" as used in the specification and claims indicates at least one of the connected objects, e.g., A and / or B indicates three cases: only A is present, only B is present, and both A and B are present.

[0025] In the examples of the present application, the terms "exemplary" or "for example" are intended to provide an example, illustration, or explanation. Any embodiment or design solution described as "exemplary" or "for example" in the examples of the present application should not be construed as preferred or advantageous over other embodiments or design solutions. Strictly speaking, the terms "exemplary" or "for example" are used for the purpose of presenting the relevant concept in a concrete form.

[0026] The techniques described in this specification are not limited to 5th-generation (5G) systems and subsequent evolved communication systems, nor are they limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but may also be used in various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems.

[0027] The terms "system" and "network" are often used interchangeably. A CDMA system can implement radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. UTRA includes Wideband Code Division Multiple Access (WCDMA) and other CDMA variations. A TDMA system can implement radio technologies such as Global System for Mobile Communication (GSM). An OFDMA system can implement radio technologies such as Ultra Mobile Broadband (UMB), Evolution-UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). LTE and higher LTE (such as LTE-A) are newer versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization called "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization called "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used with other systems and radio technologies in addition to those mentioned above.

[0028] In the related art, as shown in Fig. 1, there is a problem that RAN does not support service realization, so a Core Network (CN) node is required as an agent of RAN to provide public information via a service realization interface (e.g., Application Programming Interface (API)) to be called by consumers. Since the frequency with which RAN provides information may be high, the amount of data to be measured and published is also relatively large.

[0029] If a tunnel (also referred to as a channel) can be established between a CN node and a RAN, the RAN can easily broadcast RAN public information via the channel.

[0030] Problem 1: How to establish a channel between a CN node and a RAN node. Problem 2: Which network elements decide what information gets sent over the channel? Question 3: What public information should not be sent over the channel?
