Description

Method and device for adjusting load between carriers

This application requires the priority of the Chinese patent application submitted to the State Intellectual Property Office of China on December 17, 2018 with the application number 201811539829.3 and the invention titled "An Inter-Carrier Load Adjustment Method and Device", the entire content of which is cited by reference Incorporated in this application.

Technical field

The present application relates to the field of communication technology, and in particular, to a method and device for adjusting load between carriers.

Background technique

Universal Universal Mobile Telecommunications System (UMTS) networks are all multi-carrier networks, some sites are two-carrier networks, some sites are three-carrier networks, and at most sites are seven-carrier networks. However, in the current network, due to differences in frequency between carriers, differences in capabilities of radio remote units (RRU), differences in antenna models, heights, etc., there are also differences in coverage between carriers, resulting in differences between carriers The difference in the number of users, that is, the unbalanced load between carriers, some carriers have more users, more power and codeword consumption, poor user experience, and some carriers have fewer users and low resource utilization.

The terminal device has the following user states in the network: idle state, CELL_PCH (a RRC connected mode, where either DCCH nor DTCH is available, only can use paging channel for current cell) state, CELL_DCH (a RRC connected mode) where Both DCCH and DTCH are available) and CELL_FACH (a RRC connected mode where DCN or DTCH is available, only can use cell-forward access channel) state. Similar to the CELL_PCH state, there is also a user state: URA_PCH (a RRC connected mode where DCN nor DTCH is available, can use paging channels for some cells) state. For the terminal device in the idle state, CELL_DCH and CELL_FACH state, there already exists a corresponding inter-carrier load adjustment scheme.

However, the camping strategy in the IDEL state (mainly the IDEL state random parking strategy), for example, the minimum access threshold for F1 carrier users is set to -18dB, and the minimum access threshold for F2 carrier users is set to -14dB, due to the threshold Manual setting is required. The load conditions of different sites are different, and the load will change with the free and busy time, so it is impossible to give a reasonable and real-time setting plan.

During the business process (that is, the terminal device is in the CELL_FACH state), the switching strategy (mainly including direct retry decision (DRD) and load reshuffling (LDR) strategy), such as F1 carrier users during the call, Or, during web browsing, the F1 carrier user is forced to switch to the F2 carrier. Due to the increase of the handover process, delay will be introduced first in the handover process, and for the blind handover process, due to the difference in coverage between carriers, the handover failure of the handover is introduced. The key performance indicator (KPI) deterioration problem is introduced. The business process Switching in will lead to poor user experience (the switching process introduces mute, noise and delayed experience).

Based on the current scenario of enhanced fast dormancy (EFD) and CELL_PCH, the terminal equipment is in the CELL_PCH state for a large amount of time, and the CELL_PCH state users account for more than 50%. The idle state residence strategy is insufficient to adjust the inter-carrier load in a timely manner Reduce the negative gain brought by the subsequent switching process.

Therefore, there is an urgent need to provide an adjustment solution for the inter-carrier load based on the CELL_PCH state or the URA_PCH state.

The following describes the embodiments of the present application with reference to the drawings in the embodiments of the present application.

The network in this application may be a UMTS network or other networks. The network is a multi-carrier network. Each carrier or each frequency band corresponds to a cell. The cells corresponding to these multiple carriers may belong to one network device, or may belong to multiple network devices, and the multiple network devices are controlled by a radio network controller (RNC).

The terminal device may be a mobile phone, a tablet, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, and industrial control ( wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical, wireless terminal in smart grid, transportation safety Wireless terminals in smart cities, wireless terminals in smart cities, wireless terminals in smart homes, etc. The embodiments of the present application do not limit the application scenarios. Terminal equipment may sometimes be called user equipment (user equipment (UE), access terminal equipment, UE unit, mobile station, mobile station, remote station, remote terminal equipment, mobile device, terminal), wireless communication device, UE Agent or UE device, etc.

It should be noted that the terms "system" and "network" in the embodiments of the present application may be used interchangeably. "Multiple" refers to two or more. In view of this, in the embodiments of the present application, "multiple" may also be understood as "at least two". "And/or" describes the relationship of the related objects, indicating that there can be three relationships, for example, A and/or B, which can indicate: there are three cases of A alone, A and B at the same time, B alone. In addition, the character "/", unless otherwise specified, generally indicates that the related object is a "or" relationship.

First, briefly introduce the four states of the UE involved in this application:

·CELL_DCH status

The UE occupies dedicated channel resources and occupies more wireless resources, which is suitable for high-speed continuous data transmission.

·CELL_FACH status

The UE uses a common channel to send or receive data, which occupies fewer resources. Due to the resource limitations of RACH and FACH, the CELL_FACH state is suitable for low-speed data transmission.

·CELL_PCH status

In the upstream direction, the UE cannot send signaling messages. If there is upstream data to be sent, you need to migrate to CELL_FACH or CELL_DCH through the CELL UPDATE process.

In the downlink direction, the UE uses discontinuous reception (DRX) technology to monitor the information on the PCH channel at a specific paging moment to receive paging. If the UE in the CELL_PCH state is in a WCDMA network, UTRAN can obtain the cell where the UE is currently located and page the UE within the range of the cell. After moving to a new cell, the UE needs to perform cell reselection through the CELL Update message.

· URA_PCH status

The difference from the CELL_PCH state is that if a UE in the URA_PCH state is in a WCDMA network, UTRAN can obtain the UTRAN registration area (URA) where the UE is currently located and page the UE within the range of the URA. After moving to a new URA, the UE needs to make a URA change through the URA UPDATE message.

Then, the following introduces the load balancing strategy and service guarantee strategy between the carriers in the idle state, CELL_DCH state, and CELL_FACH state:

Based on carrier differences and combining customer demands, the existing network requires many adjustment actions to adjust the carrier load and meet customer demands. For example, in a scenario where multi-carrier networking gives priority to guaranteeing voice services, in order to give priority to guaranteeing voice services, a tiered strategy for resident services may be adopted, for example, divided into F1-Fn carriers. All carriers support R99 services and high-speed packet access (HSPA) services ("H services" for short), and F1 preferentially carries R99 services, and F2, F3, F4, ..., Fn preferentially bear H services.

Resident strategy:

Users in the idle state, CELL_PCH state, and URA_PCH state tend to reside in F1. In order to make the idle users in F2, F3, F4, ..., Fn cells reselect to F1 more quickly, users in idle state, CELL_PCH state and URA_PCH state tend to camp on F1. CELL_FACH users are handled separately and reside on the original carrier.

Access state strategy (CELL_DCH state corresponding strategy):

Voice services and combined services are directly accessed in the source cell (the cell that the user accesses in the RRC phase).

Data business

1) Hierarchical access to other cells based on HSPA+ technology satisfaction, using DRD mode.

2) Based on business hierarchical access to other cells, using DRD mode.

3) Hierarchical access to other cells based on load, etc., using the DRD method.

Connected state strategy (CELL_FACH state corresponding strategy):

Different frequency switching based on load;

Inter-frequency switching based on coverage.

Among them, load-based inter-frequency handover includes LDR strategy and so on. The coverage-based inter-frequency handover may specifically be a coverage-based inter-frequency handover.

Regarding the above several load balancing strategies and service guarantee strategies between carriers, as shown in FIG. 1, it is a schematic diagram of load adjustment between carriers based on different load balancing strategies. When idle, F1 preferentially carries R99 services. F2, F3, F4...Fn preferentially bear H services. When the UE performing H service on F2, F3, F4...Fn enters the idle state, it can switch to F1. This switching strategy can be referred to as preferential camping; when the idle UE on F1 connects When entering the network to enter the connected state, you can blindly switch (blind handover, blind HO) to any carrier in F2, F3, F4...Fn; if F2, F3, F4...Fn is overloaded, the UE in the connected state can also Inter-freq HO from any carrier in F2, F3, F4...Fn where it is currently located to any other inter-frequency carrier in F2, F3, F4...Fn, as shown in Figure 1, Fn, The connected UE on F4 switches to F3.

Specifically, for the idle state dwelling strategy, the idle state dwelling strategy parameters shown in Table 1 to Table 2 below need to be manually set and carried to the UE through system messages. The UE cannot obtain each carrier load on the network side at this time. The UE is based on The following parameters are configured and combined with coverage and other conditions to complete the reselection and camping between carriers. The following Tables 1 to 2 describe the switching of F1 to F3 carriers or cells as an example, and the switching of other carriers can refer to the settings of these parameters.

Table 1

Table 2

Among them, IdleQoffset2sn represents a parameter that forces a tendency to reside.

For the switching strategies in the business process, there are mainly DRD and LDR strategies.

DRD refers to the process in which the RNC selects a suitable cell for the UE to access, and is one of the methods for the UE to access the network. Figure 2 is a schematic diagram of the process of direct retry decision. As shown in Figure 2, the DRD process includes:

S201. The RNC triggers DRD according to relevant conditions.

S202. The RNC screens the DRD candidate neighboring cells that meet the conditions.

S203. The RNC selects the target cell to make an access attempt.

S204. Determine whether the cell is successfully accessed.

S205. If the access is successful, the DRD is successful and the process ends.

S206. If the access fails, the DRD fails, and the process proceeds to S207.

S207. Handle cell access failure.

Specifically, the cell access failure processing includes: if the inter-frequency DRD fails, the inter-system DRD can be performed; if the inter-system DRD fails, the process ends. The heterogeneous system refers to communication systems of different standards, such as GSM and LTE.

The inter-frequency load balancing feature supports switching some users to inter-frequency co-coverage cells when the cell is in the primary congestion state to reduce the load of the local cell. This feature is also called inter-frequency load switching. Figure 3 is a schematic diagram of the process of inter-frequency load balancing. The process of LDR inter-frequency load balancing includes:

S301. The RNC triggers LDR inter-frequency load balancing according to relevant conditions (for example, whether the load threshold of each resource of the cell reaches the LDR threshold). The cell is in the CELL_FACH state, and the RNC screens qualified users to perform inter-frequency handover.

Among them, LDR is aimed at a state of resource congestion, and releasing this state requires some actions to achieve. Inter-frequency handover is one of these actions. When the function of LDR inter-frequency load balancing is turned on, the inter-frequency switching action is triggered.

S302. Configure an LDR switching strategy. Among them, blind handover has priority.

S303. Determine whether there is a blind handover neighbor cell that meets the conditions.

S304. If there is a blind handover neighbor cell that meets the conditions, perform a blind handover action, and select the configured blind handover neighbor cell to perform inter-frequency blind handover.

S305. If there is no blind handover neighbor cell that meets the condition, determine whether there is a measurement handover neighbor cell that meets the condition.

S306: If the inter-frequency handover based on measurement is selected, the inter-frequency neighboring cell that meets the conditions based on the measurement report is selected to perform inter-frequency handover.

S307. The LDR action is completed, and the RNC determines whether to execute the next LDR action based on the current load.

S308. In S305, if there is no eligible measurement switching neighbor cell, the next LDR action is performed.

However, as mentioned earlier, the camping strategy in the idle state (mainly there is a random camping strategy for idle users), for example, the minimum access threshold for F1 carrier users is set to -18dB, and the minimum access threshold for F2 carrier users is set to -14dB. However, since the threshold needs to be set manually, the load conditions of different sites are different, and the load will change with the free and busy time, so a reasonable and real-time setting scheme cannot be given.

Switching strategies in the business process (mainly DRD and LDR strategies), for example, F1 carrier users are forced to switch F1 carrier to F2 carrier during a call or during web browsing. Due to the increase of the handover process, delay will first be introduced during the handover process, and for the blind handover process, due to the difference in coverage between carriers, the handover failure will cause the KPI deterioration problem, and the handover in the business process will result in a poor user experience (The switching process introduces mute, noise and delayed experience).

This application is based on the currently opened EFD and CELL_PCH scenarios, and the UE is in the CELL_PCH state for a large amount of time. PCH state users account for more than 50%, idle state parking strategy adjusts inter-carrier RRC times and RAB phase DRD adjustment times are insufficient to adjust inter-carrier load in a timely manner, through PCH state redirection strategy combined with inter-carrier load (CELL_PCH state, RNC can Obtain the inter-carrier load situation) Adjust the idle state distribution of the redirected user between carriers, and can reduce the negative gain brought by the subsequent handover process. It should be noted that the PCH state includes the CELL_PCH and URA_PCH states. The technical solution of the present application is also applicable to the URA_PCH state, and the implementation process is the same.

FIG. 4 is a schematic flowchart of a method for adjusting an inter-carrier load according to an embodiment of the present application, specifically, the inter-carrier load balancing based on the PCH state. The RNC can adjust the load between carriers, and of course it can be other controllers or network devices. This embodiment is described by taking the RNC adjusting the inter-carrier load as an example. The method includes the following steps:

S401. Detect the load between multiple carriers in real time.

An office in the network can include multiple carriers, for example, an office can be up to 7 carriers. RNC detects the load between each carrier in real time. The load between the carriers is the difference between the loads of the two carriers.

S402. When it is determined that the load difference between the first carrier and any one of the multiple carriers is greater than or equal to the load threshold, select the terminal device on the first carrier in the first state, the first The states include CELL_PCH state or URA_PCH state.

To trigger the adjustment of the inter-carrier load, there is an inter-carrier load threshold. When the load difference between one carrier (the first carrier) and any other carrier is greater than or equal to the threshold, the adjustment of the inter-carrier load is triggered. For example, F1 load-F2 load> inter-carrier load threshold, then trigger F1 load adjustment.

There may be UEs in different states on the first carrier, from which UEs in the CELL_PCH state or URA_PCH state are selected. The CELL_PCH state or the URA_PCH state means that the UE inactivity timer is not released to the idle state without timeout and does not trigger the state transition. Selecting UEs in the CELL_PCH state or URA_PCH state may be selecting all UEs in the CELL_PCH state or URA_PCH state on the first carrier, or may select UEs in the CELL_PCH state or URA_PCH state on the first carrier. There are many strategies to choose from, and there are no restrictions here.

S403. Determine the second carrier according to the selected terminal device in the first state.

The second carrier is the carrier after the UE in the CELL_PCH state or the URA_PCH state is switched. To determine the second carrier, it is necessary to ensure that the UE in the CELL_PCH state or URA_PCH state is switched to the second carrier, and after entering the connected state, the second carrier can ensure the resource allocation of the UE on it and ensure the normal operation of services. In other words, it is determined whether the second carrier satisfies the load sharing condition.

Specifically, S403 includes: determining the second carrier according to the selected number of the terminal devices in the first state and the load on any other carrier among the multiple carriers. Optionally, the second carrier is the carrier with the smallest load among the multiple carriers. That is, consider the number of UEs that are about to switch to the CELL_PCH state or URA_PCH state. If there are too many UEs, consider whether the second carrier is the best-carrying carrier, for example, whether it is the least-loaded carrier other than the first carrier Of the carrier.

S404. Send a redirection command to the second carrier, where the redirection command is used to request that the terminal device in the first state is redirected to the second carrier, and the redirection command includes the second Carrier identification.

Optionally, after redirecting to the second carrier, the terminal device enters an idle state.

Optionally, after S404, the following step may be further included: releasing the connection between the terminal device and the network on the first carrier.

As shown in the schematic diagram of the terminal device redirection based on the CELL_PCH state shown in FIG. 5, before the adjustment, the RNC detects that there are three UEs in the CELL_PCH state on F1, and only one UE in the CELL_PCH state on F2, assuming that F1 and F2 There is only UE in CELL_PCH state. Assuming that the threshold of the load difference between carriers is 1, the load on F1-the load on F2 = 2, which exceeds the threshold. Then, the UE in the CELL_PCH state is redirected, the UE in the CELL_PCH state on F1 is redirected to the F2 carrier, and the network connection of the UE in the CELL_PCH state on F1 and F2 is disconnected. The UE in the CELL_PCH state enters the idle state. After adjustment, there are two UEs on F1 and F2, and the load balance is achieved.

RNC monitors the load difference between carriers in real time, and adjusts the threshold through the set load. When the load difference between carriers exceeds the set threshold, the RNC selects the target frequency point through the load discrimination result between carriers, and then selects the CELL_PCH state user to trigger the RRC release redirect function to For the target frequency point, when the user accesses the network again, the target frequency point resource will be consumed, thereby reducing the purpose of the current cell load.

During the inter-carrier load adjustment process, by introducing the CELL_PCH state inter-carrier load judgment process and selecting the CELL_PCH state user to trigger the RRC release redirection function based on the inter-carrier load discrimination result, the inter-carrier load is balanced by adjusting the inter-carrier user residence The CELL_PCH state is similar to the IDEL state for users, and the load adjustment action at this time will not affect the user experience or the network KPI.

In this way, as shown in FIG. 6, when terminal devices are in different states, different load balancing strategies are used. For UEs in different states, different load balancing strategies can be adopted to perform load balancing. Specifically, as shown in FIG. 6, the load adjustment on the two carriers F1 and F2, the UE in the idle state can camp on F1 or F2 through the reselection tendency, and the UE in the CELL_DCH state can choose to camp on F1 through DRD Or F2, the UE in the CELL_FACH state can choose to reside in F1 or F2 through the LDR, and the UE in the CELL_PCH state can choose to stay in F1 or F2 based on the load adjustment method of the present application. Thus, the load balancing strategy of UEs in different states is improved.

According to a method for adjusting an inter-carrier load provided by an embodiment of the present application, when a terminal device is in the CELL_PCH state or URA_PCH state, it is very likely to quickly enter the service transmission process. By detecting the load between multiple carriers in real time, when determining the first When the load difference between the carrier and any one of the multiple carriers is greater than or equal to the load threshold, select the terminal device on the first carrier in the CELL_PCH state or URA_PCH state, determine the second carrier, and redirect the terminal device to The second carrier. Redirect the terminal equipment in the CELL_PCH state or URA_PCH state and located on the carrier with excessive load to the carrier with a lighter load in advance, which can make the terminal equipment balance the load between the carriers when entering the service transmission process, which can give the terminal equipment Provide sufficient resource allocation to ensure the normal operation of the business.
