Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. In the description and in the claims "and/or" means at least one of the connected objects.

The techniques described herein are not limited to Long Time Evolution (LTE)/LTE Evolution (LTE-Advanced) systems, and may also be used for 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. The terms "system" and "network" are often used interchangeably. CDMA systems may implement Radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA), and so on. UTRA includes Wideband CDMA (Wideband Code Division Multiple Access, WCDMA) and other CDMA variants. TDMA systems may implement radio technologies such as Global System for Mobile communications (GSM). The OFDMA system may implement radio technologies such as Ultra Mobile Broadband (UMB), evolved-UTRA (E-UTRA), IEEE 802.11(Wi-Fi), IEEE 802.16(WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are parts of the Universal Mobile Telecommunications System (UMTS). LTE and higher LTE (e.g., LTE-A) are new UMTS releases that use E-UTRA. UTRA, E-UTRA, UMTS, LTE-A, and GSM are described in documents from an organization named "third Generation Partnership Project" (3 GPP). CDMA2000 and UMB are described in documents from an organization named "third generation partnership project 2" (3GPP 2). The techniques described herein may be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. However, the following description describes the NR system for purposes of example, and LTE as well as NR system terminology is used in much of the description below, although the techniques may also be applied to applications other than the system applications described above.

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 described methods may be performed in an order different than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

As described in the background art, the scenarios and service types supported by the 5G network are more diversified, and the requirements of these services on frequency and the network configuration are greatly different from the conventional services, and sometimes they need to be separately loaded through different frequency points or cells. For example, low latency services generally require a shorter frame structure and faster uplink and downlink switching periods, and frequency bins or cells supporting the eMBB service may not be able to provide this configuration.

A typical deployment scenario of a 5G network supporting multiple services is shown in fig. 1, where a base station operating at a frequency point with a lower frequency (e.g., 2.6GHz) is used to provide basic coverage for carrying voice and mobile broadband services (eMBB services), and a base station operating at multiple frequency points with a higher frequency (e.g., 4.9GHz) is deployed in a coverage range of 2.6GHz for carrying low-latency high-reliability services (industrial control, car networking, and the like).

The 2.6GHz frequency point is usually set in the network with higher priority, and a terminal which supports both broadband service and low-delay high-reliability service in the network usually resides in the 2.6GHz frequency point with higher priority. If the flow and mechanism in the prior art are adopted, when the paging of the terminal of the low-delay high-reliability service is terminated (MT), after the paging message sent by the core network is received, the 2.6GHz base station and/or the 4.9GHz base station initiates the paging to the terminal, because the terminal resides in the 2.6GHz base station, the paging message sent by the 2.6GHz base station is only intercepted, and the random access is initiated in the cell, so as to establish the RRC connection. And when the terminal finds that the accessed cell does not support the low-delay high-reliability service, the terminal is switched to the 4.9GHz cell to initiate a service request. The above procedure will result in unnecessary signaling overhead and an increase in service access delay. Here, the service of the MT refers to a service initiated by a network, and the service of the terminal-initiated (MO) refers to a service initiated by a terminal.

It can be seen that, in the prior art, there are some disadvantages when supporting a 5G diversified scenario or service, for example, a cell where a terminal resides may not support initiation of a certain service, and a problem of time delay and large signaling consumption is caused by switching to a supported cell to initiate a service after access is required.

In order to solve the above problem, embodiments of the present invention provide an information processing method, which can implement a service-based access process, and reduce service access delay and signaling overhead.

Referring to fig. 2, fig. 2 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a base station 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The Base Station 12 may be various Base stations and/or network elements of a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station 12 may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, and it should be noted that in the embodiment of the present invention only takes the Base Station in the NR system as an example, but does not limit the specific type of base station.

The base stations 12 may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the 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 transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

Base station 12 may communicate wirelessly with terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, 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.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to base station 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from base station 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

Referring to fig. 3, an information processing method according to an embodiment of the present invention, when applied to a terminal side, includes:

step 31, determining the service identification information of the target service.

Here, the service identification information of the target service is used to assist the terminal to obtain the service type of the target service or determine a cell or a frequency suitable for the target service to access. Specifically, the service identification information may include at least one of a service related identification and a network slice identification. The service-related identifier may specifically be a service type identifier (e.g., identifier information indicating that the service is an eMBB service, an mtc service, or a URLLC service).

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

The target service may also be a terminal initiated (MO) service. For the MO service, because the MO service is initiated by the terminal, the terminal may determine the service identification information of the target service according to the mapping relationship between the service and the service identification information that is obtained in advance. Here, the mapping relationship may be configured in advance on the terminal side, and the mapping relationship may be in the form of a mapping template or in the form of a mapping policy. Of course, the mapping relationship may also be issued to the terminal by the network in the initial registration or update process of the terminal.

And step 32, determining the relevant information of the target cell matched with the service identification information of the target service.

Here, the cell-related information indicates access information of a target cell supporting the target service to assist the terminal to directly access the target cell. Specifically, the cell related information may include a frequency and/or a system message of a cell operation, and the target cell related information may include a target frequency and/or a target system message of a target cell operation.

Step 33, initiating access to the one or more target cells according to the target cell related information.

Here, the terminal may directly initiate access to the target cell according to the target cell related information, so as to directly access the target cell capable of supporting the target service, and may start a service flow of the corresponding target service after successful access.

It can be seen from the above steps that, in the information processing method of the embodiment of the present invention, the terminal can directly access the target cell capable of supporting the target service, thereby avoiding the cell switching process caused by the access cell not supporting the target service in the prior art, and reducing the service access delay and the signaling overhead of the access process.

As an implementation manner of the foregoing step 32, the terminal may obtain in advance a corresponding relationship between service identification information and cell related information, where the corresponding relationship is configured in advance on the terminal, or is sent to the terminal by a base station, or is sent to the terminal by a core network. Then, in the above step 32, the terminal determines the target cell related information matched with the service identification information of the target service according to the corresponding relationship. Based on the above implementation of step 32, various implementations of step 33 described above are further provided below.

According to at least one embodiment of the invention, the target cell related information is a target frequency. In step 33, the terminal may read the system message of the target cell by synchronizing with the target cell operating on the target frequency, and initiate access to one or more target cells according to the system message of the target cell. Further, considering cell signals and other factors, in step 33, the terminal may further select one or more target cells to initiate access according to the signal quality of the serving/camped cell and/or the target cell. Here, the signal quality may include a reference signal received strength and/or a measurement result of reference signal received quality. In addition, the serving/camping cell refers to a cell to which the terminal is currently accessed, and the cell may be a current camping cell or a serving cell of the terminal, and usually, when the terminal is in an idle state, the cell to which the terminal is accessed is called a camping cell; when the terminal is in the connected state, a cell accessed by the terminal is called a serving cell.

According to at least one embodiment of the invention, the target cell related information is a target frequency. In step 33, the terminal may receive a system message of a target cell operating on the target frequency, which is broadcast by the camping/serving cell, where the system message of the target cell at least includes cell access essential information, and specifically, the cell access essential information may generally include a frame structure, a carrier bandwidth, a random access configuration, and the like; and the terminal initiates access to one or more target cells according to the system message of the target cell. In addition, the camping/serving cell broadcasting may also be based on a terminal request, and broadcast the system message of the target cell operating at the target frequency, at this time, the terminal may also request the camping/serving cell to broadcast the system message of the target cell operating at the target frequency, and then receive the system message of the target cell operating at the target frequency, which is broadcast by the camping/serving cell in response to the request.

Here, when the System message of the target cell may further include System Frame Number (SFN) difference information between the camping/serving cell and the target cell, therefore, when the System message of the target cell does not include the SFN difference information between the camping/serving cell and the target cell, the terminal may synchronize with the target cell according to the System message of the target cell, and initiate access to the target cell after synchronization is completed; when the system message of the target cell also comprises the difference value information of the system frame numbers of the resident/service cell and the target cell, the terminal can directly initiate access to the target cell according to the system message of the target cell, thereby completing the cell access process more quickly.

According to at least one embodiment of the invention, the target cell related information is a target frequency. In the step 33, the terminal receives a system message configured for multiple cells broadcasted by the camping/serving cell, where the system message is a system message shared by multiple cells. Then, the terminal initiates access to the target cell of the target frequency according to the regional system message.

According to at least one embodiment of the invention, the target cell related information is a target frequency. In step 33, the terminal may receive a camping/serving cell system message broadcasted by the camping/serving cell, where the camping/serving cell system message indicates a cell system message corresponding to the target frequency; and then the terminal acquires the cell system message corresponding to the target frequency according to the resident/service cell system message and initiates access according to the cell system message corresponding to the target frequency. For example, in minimum system information (minimum SI) of the camped/serving cell, it may be indicated that a cell system message corresponding to the target frequency corresponds to a certain SIB of the camped cell, and then the terminal may obtain the cell system message corresponding to the target frequency by reading the SIB of the camped cell.

According to at least one embodiment of the invention, the target cell related information is a target system message. In the above step 33, the terminal may receive the target system message broadcasted by the camping/serving cell, where the target system message includes the target frequency; then, the terminal acquires the target frequency carried in the target system message, reads the system message of the target cell by synchronizing with the target cell working on the target frequency, and initiates access to the target cell according to the system message of the target cell. Further, considering cell signals and other factors, in step 33, the terminal may further select one or more target cells to initiate access according to the signal quality of the serving/camped cell and/or the target cell. Here, the signal quality may include a reference signal received strength and/or a measurement result of reference signal received quality.

According to at least one embodiment of the invention, the target cell related information is a target system message. In the above step 33, the terminal may receive the target system message broadcasted by the camping/serving cell, where the target system message includes the target frequency and the cell access necessary information of the target cell; specifically, the cell access requirement information may generally include a frame structure, a carrier bandwidth, a random access configuration, and the like. Then, the terminal initiates access to the target cell according to the target system message. In addition, the camping/serving cell broadcasting may also be based on a terminal request, and the target system message is broadcasted, and at this time, the terminal may also request the camping/serving cell to broadcast the target system message first, and then receive the target system message broadcasted by the camping/serving cell in response to the request.

Here, when the target System message may further include System Frame Number (SFN) difference information between the camping/serving cell and the target cell, therefore, when the target System message does not include the SFN difference information between the camping/serving cell and the target cell, the terminal may synchronize with the target cell according to the target System message, and initiate access to the target cell after synchronization is completed; when the target system message further includes the system frame number difference information between the resident/serving cell and the target cell, the terminal may directly initiate access to the target cell according to the target system message, so that the cell access process may be completed more quickly.

As another implementation manner of the foregoing step 32, the camping/serving cell may broadcast service identifier information supported by the camping/serving cell and the neighboring cell. Therefore, in step 32, the terminal may receive the service identifier information supported by the camping/serving cell and the neighboring cell broadcasted by the camping/serving cell, determine the target cell supporting the service identifier information of the target service, and obtain the target cell related information of the target cell. Here, the target cell-related information may include a target frequency and/or a target system message; then, in the above step 33, the terminal may initiate access to the one or more target cells based on the target cell related information.

As another implementation manner of the step 32, the terminal supports camping in multiple cells, and each cell may broadcast the service identifier information supported by the cell. At this time, in step 32, the terminal may receive the service identifier information supported by the cell broadcasted by the multiple cells, determine the target cell supporting the service identifier information of the target service, and obtain the target cell related information of the target cell.

Specifically, the service identification information may include at least one of a service related identification and a network slice identification. The service-related identifier may specifically be a service type identifier (e.g., identifier information indicating that the service is an eMBB service, an mtc service, or a URLLC service).

And step 42, sending a paging message to the terminal according to the paging information, wherein the paging message carries service identification information of the target service.

The base station adds the service identification information of the target service in the sent paging message, so that the paged terminal determines the target cell related information matched with the service identification information of the target service after receiving the paging message, and then accesses to one or more target cells according to the target cell related information.

Through the steps, the embodiment of the invention can help the terminal to access the target cell capable of supporting the target service, and can start the service process of the corresponding target service after the access is successful, thereby avoiding the cell switching process caused by the fact that the access cell does not support the target service in the prior art, and reducing the service access time delay and the signaling overhead of the access process.

According to at least one embodiment of the present invention, the base station may further send second broadcast information of the camped/serving cell, where the second broadcast information includes service identification information of a service supported by a neighboring cell of the camped/serving cell.

According to at least one embodiment of the present invention, the base station may further broadcast a system message corresponding to a neighboring cell of the camping/serving cell, so that the terminal may initiate access to the neighboring cell based on the system message of the neighboring cell broadcast by the camping/serving cell. Further, the base station may also broadcast a system message corresponding to the neighboring cell according to a request of the terminal, for example, the base station may receive a system message that is sent by the terminal and requests to broadcast a target cell operating at a predetermined frequency, where the target cell is a neighboring cell of the camping/serving cell; and the base station broadcasts the system message of the target cell according to the request of the terminal.

According to at least one embodiment of the present invention, the base station may further broadcast a first system message of a camping/serving cell, where the first system message indicates a cell system message corresponding to a predetermined frequency, so as to assist a terminal to read the cell system message corresponding to the predetermined frequency from the system message of the cell of the base station.

Specifically, the service identification information may include at least one of a service related identification and a network slice identification. The service-related identifier may specifically be a service type identifier (for example, identifier information indicating that the service is an eMBB service, an mtc service, or a URLLC service).

Step 52, when the base station supports the target service in its own cell, the base station sends a paging message in its own cell, where the paging message carries service identification information of the target service;

here, the base station transmits the paging message only when its cell supports the target service, and ignores the paging message and does not transmit the paging message when its cell does not support the target service.

Through the steps, the embodiment of the invention directly identifies whether the cell supports the target service at the base station side, so that the terminal can directly access the sending cell of the paging message, the processing at the terminal side is simplified, the terminal can directly access the target cell capable of supporting the target service, the cell switching process caused by the fact that the access cell does not support the target service in the prior art is avoided, and the service access time delay and the signaling overhead of the access process are reduced.
