The techniques described herein are not limited to Long Time Evolution (LTE)/LTE-Advanced (LTE-A) systems, and may also be used in various wireless communication systems, such as Code Division Multiple Access (Code Division Multiple Access) Access, CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-Carrier Frequency Division Multiple Access (OFDMA) address (Single-carrier Frequency-Division Multiple Access, SC-FDMA) and other systems. The terms "system" and "network" are often used interchangeably. A CDMA system may implement radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA). UTRA includes Wideband CodeDivision Multiple Access (WCDMA) and other CDMA variants. A TDMA system may implement a radio technology such as the Global System for Mobile Communication (GSM). The OFDMA system can realize radios 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. technology.

The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made in the function and arrangement of elements discussed without departing from the spirit and scope of the disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the methods described may be performed in an order different from that described, and various steps may be added, omitted, or combined. Additionally, features described with reference to some examples may be combined in other examples.

As described in the background art, the scenarios and service types supported by 5G networks are more diverse. The frequency requirements and network configuration of these services are quite different from those of traditional services, and sometimes they need to be carried separately through different frequency points or cells. For example, a low-latency service usually requires a shorter frame structure and a faster uplink-downlink conversion period, and the frequency or cell that supports the eMBB service may not be able to provide this configuration.

A typical 5G network deployment scenario that supports multiple services is shown in Figure 1. Base stations operating at lower frequencies (such as 2.6GHz) are used to provide basic coverage and carry voice and mobile broadband services (eMBB services). ), deploying base stations operating at multiple high-frequency frequency points (such as 4.9GHz) under the coverage of 2.6GHz to carry low-latency and high-reliability services (industrial control, Internet of Vehicles, etc.).

In the above network, the 2.6GHz frequency is usually set with a higher priority, and the terminals that support both broadband services and low-latency and high-reliability services in the network usually reside on the 2.6GHz frequency with a higher priority. If the procedures and mechanisms of the prior art are adopted, when the terminal terminated (MT, MobileTerminated) paging of the low-latency and high-reliability service occurs, after receiving the paging message sent by the core network, the 2.6GHz base station and/or the 4.9GHz base station When paging is initiated to the terminal, since the terminal resides on the 2.6GHz base station, it will only listen to the paging message sent by the 2.6GHz base station, and initiate random access in the cell to establish an RRC connection. When the terminal finds that the accessed cell does not support low-latency and high-reliability services, it will switch to the 4.9GHz cell to initiate a service request. The above process will lead to unnecessary signaling overhead and increase of service access delay. Here, the service of the MT refers to the service initiated by the network, and the service initiated by the terminal (MO, Mobile Original) refers to the service initiated by the terminal.

It can be seen that the existing technology has some deficiencies in supporting 5G diversified scenarios or services. For example, the cell where the terminal resides may not be able to support the initiation of a certain service, and it needs to be switched to a supported cell to initiate a service. The problem of prolongation and signaling consumption.

To solve the above problem, an embodiment of the present invention provides an information processing method, which can implement a service-based access process and reduce service access delay and signaling overhead.

Base stations 12 may communicate with terminals 11 under the control of a base station controller, which in various examples may be part of a core network or some base station. Some base stations may communicate control information or user data with the core network through the backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. Wireless communication systems may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on these multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be sent on a different carrier and may carry control information (eg, reference signals, control channels, etc.), overhead information, data, and the like.

Base station 12 may wirelessly communicate with terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of an access point may be divided into sectors that make up only a portion of the coverage area. A wireless communication system may include different types of base stations (eg, macro base stations, micro base stations, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

A communication link in a wireless communication system may include an uplink for carrying uplink (UL) transmissions (eg, from terminal 11 to base station 12), or for carrying downlink (DL) transmissions Downlink (eg, from base station 12 to terminal 11). UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be performed using licensed bands, unlicensed bands, or both. Similarly, uplink transmissions may be performed using licensed frequency bands, unlicensed frequency bands, or both.

The service-related identifier may specifically be a service type identifier (eg, identifier information indicating that the service is an eMBB service, a mMTC service, or a URLLC service).

Here, the above-mentioned target service may be a service corresponding to the paging message, that is, the target service is a terminal termination (MT) service in the paging message initiated by the network. At this time, in the above step 31, the terminal may receive the paging message sent by the network device, the paging message carries the service identification information of the target service, and then obtain the service identification information of the target service from the paging message.
