Background

At present, an eMTC user equipment UE supporting only a 1.4MHz narrowband is available, and the eMTC UE has a low transmission rate but has high requirements on complexity and cost. eMTC UEs need to enter the base station through a Physical Random Access Channel (PRACH). Usually, the response of the PRACH by the base station is through a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH). Because the eMTC UE cannot decode the PDCCH, the eMTC UE cannot receive the base station's response as a normal user does. When the eMTC user performs uplink random access, the base station does not know the user type, which may cause an ineffective effect on the eMTC UE.

Detailed Description

The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.

The first embodiment of the method comprises the following steps:

as shown in fig. 1, the present embodiment provides an information processing method, which is applied to a base station configured with a first random access resource; the method comprises the following steps:

step S110: configuring a second random access resource;

step S120: grouping the first random access resource and the second random access resource to form a first random access resource group and a second random access resource group; the first random access resource group is used for random access of first-class user equipment; the second random access resource group is used for random access of second type user equipment;

step S130: acquiring a first random access parameter corresponding to the first random access resource group; acquiring a second random access parameter corresponding to the second random access resource group;

step S140: and sending the first random access parameter to the first class of users and sending the second random access parameter to the second class of user equipment, wherein the first random access parameter is used for indicating the first random access resource group available for the first class of user equipment, and the second random access parameter is used for indicating the second random access resource group available for the second class of user equipment.

There are various ways to configure the second random access resource in step S110, including but not limited to the following two alternatives.

The first alternative is as follows:

the first random access resource is a random access resource which is currently used by a base station for random access of first-class user equipment, and a newly configured random access resource different from the first random access resource is also arranged in the base station; at this time, the configuring the second random access resource is to read and load a configuration parameter of the newly configured random access resource.

The second option is:

the first random access resource is a random access resource currently used by the base station for random access of the first type of user equipment, and the step S110 configures the second random access resource as a configuration parameter for acquiring the second random access resource from an external device and configuring the second random access resource. The peripheral equipment can comprise a mobile management entity MME or other management equipment of a core network and the like.

In step S120, the first random access resource and the second random access resource are regarded as a whole, and the random access resources are grouped to form a first random access resource group and a second random access resource group. The first random access resource group and the second random access resource group at least comprise one random access resource which can be used for random access of user equipment. The number of random access resources included in the first random access resource group and the second random access resource group may be the same or different.

The second type of user equipment may be user equipment supporting only the first bandwidth, for example, eMTC user equipment supporting only 1.4MHz communication technology. The first type of user equipment may be common user equipment other than the second type of user equipment, specifically, common user equipment such as 2G user equipment, 3G user equipment, and 4G user equipment.

First and second random access parameters corresponding to the first and second random access resource groups, respectively, are acquired in step S130. The first random access parameter may be identification information of a resource in the first random access resource group. The same second random access parameter may be identification information of a resource in the second random access resource group, and the like. The identification information may be identification information of random access parameters of each random access resource group, or identification range information of one random access resource. For example, the time-frequency resources corresponding to the 1 st time unit to the 5 th time unit are used for accessing the first type of user equipment, and at this time, an identifier range value from the 1 st time unit to the 5 th time unit may be given.

In step S140, the first random access parameter and the second random access parameter are respectively sent to two types of user equipments, so that the user equipments of the first type and the user equipments of the second type can be informed of which random access resource group is used for random access when performing random access, and thus, a subsequent base station can determine the type of the user equipment according to the random access resource group performed by the user equipment, and thus, the corresponding downlink channel is used to send information to the user equipments of different types.

Specifically, for example, when the base station determines that the currently randomly accessed user equipment is the common user equipment, the base station may perform information interaction such as service data with the common user equipment by using a physical downlink control channel PDCCH and a physical downlink shared channel PDSCH. When the base station determines that the current randomly accessed user equipment is the eMTC user equipment, the base station can perform information interaction such as service data with the eMTC user equipment by adopting an Enhanced Physical Downlink Control Channel (EPDCCH) and a Physical Downlink Shared Channel (PDSCH).

In summary, this embodiment provides a method for random access of different types of user equipments, which can enable different types of user equipments to access a base station by using different random access resources through division of random access resources, determine a user equipment according to a type of the random access resources, and perform information interaction with the user equipment by selecting a corresponding downlink channel, so as to solve a problem that after an eMTC user equipment is accessed in the prior art, the base station cannot perform an effective response to the eMTC user equipment. In addition, it is very important that, in the information processing method described in this embodiment, in order to reduce random access to the common user equipment as much as possible, before performing random access resource grouping, a second random access resource is newly added, so that the total number of random access resources used for the user equipment on the base station is increased, and thus it can be ensured that both the first type of user equipment and the second type of user equipment have a higher random access success rate.

The second method embodiment:

step S110: configuring a second random access resource;

The step S120 may include:

selecting part or all of the first random resources to form the first random access resource group;

selecting at least the second random access resource to form the second random access resource group;

wherein the second set of random access resources does not include the first random resource or includes a portion of the first random access resource.

In order to minimize the influence on the random access of the first type of user equipment, in this embodiment, the newly added configured second random access resources in step S110 all form the second random access resource group as much as possible; and a part or all of the first random access resources used for random access by the base station are initially used to form the first random access resource group.

Specifically, the number of the first random resources is 8; the number of the second random access resources is 4. The first random access resource grouping may be, by using the method described in this embodiment: 4 second random access resources form the second random access resource group; 8 first random access resources form the first random access resource group; the method the first random access resource packet may also be: the 4 second random access resources and the M first random access resources form a second random access resource group; 8-M first random access resources form the first random access resource group; wherein M is a positive integer less than 8.

By adopting the method of the embodiment, when the configuration of the second random access resource and the configuration of the first random access resource group and the second random access resource group are carried out, the configuration of the base station can be simplified, and the configuration of the random access resource used for the common user equipment is reduced.

The third method embodiment:

step S110: configuring a second random access resource;

The first random access resource group and the second random access resource group at least comprise time-frequency resources and pilot frequency codes;

at least one of the time-frequency resource and the pilot frequency code of the first random access resource group and the second random access resource group is different, that is, the pilot frequency codes in the first random access resource group and the second random access resource group are different and the time-frequency resource is the same, or the pilot frequency codes in the first random access resource group and the second random access resource group are the same and the time-frequency resource is different, or the pilot frequency codes in the first random access resource group and the second random access resource group are different and the time-frequency resource is also different.

The random access resources for the user equipment to randomly access the base station at least comprise time frequency resources, pilot frequency codes and other resources. The time frequency resource comprises a frequency resource and a time resource; the time frequency resources are different, i.e. at least one of the frequency resources and the time resources are different. In particular when the first random access resource group and the second random access resource group differ in that time-frequency resources are different. If the first random access resource group adopts the first frequency band for random access of the first type of user equipment, and the second random access resource group adopts the second frequency band for random access of the second type of user equipment, the base station determines the type of the user equipment according to which frequency band the frequency band sent by the random access request is located in when receiving the random access of the user equipment.

Specifically, if the first type of user equipment adopts a group A of pilot frequency codes to randomly access the base station, and the second type of user equipment adopts a group B of pilot frequency codes to randomly access the base station, even if the two types of user equipment use a common time-frequency resource to be included in the base station at the same time, the base station determines the type of the user equipment according to the group of the pilot frequency codes used by the random access of the two types of user equipment.

On the basis of the first method embodiment and the second method embodiment, the difference between the first random access resource group and the second random access resource group is specifically defined, and the method has the advantage of simplicity and convenience in implementation.

The method comprises the following steps:

step S110: configuring a second random access resource;

The step S140 may include:

transmitting the first random access parameter to the first class of user equipment by using a first broadcast channel;

transmitting the second random access parameter to the second type of user equipment by using a second broadcast channel;

the first broadcast channel is different from the second broadcast channel.

In this embodiment, in order to facilitate the different types of user equipments to determine random access parameters that need to be received, different broadcast channels corresponding to the first type of user equipment and the second type of user equipment are respectively used to broadcast the first random access parameter and the second random access parameter.

Specifically, for example, when the first type of user equipment is the common user equipment described in the first embodiment of the method, the first random access parameter is carried in the system message SIB by using a broadcast channel capable of sending a system message, and is sent together with the SIB.

For another example, the first random access parameter may carry a system message SIB and the SIB is transmitted using the same broadcast channel; and the second random access parameter may be transmitted using a broadcast channel for eMTC users on 6 resource blocks rb (resource block) on a center frequency configured for communication by the base station.

Meanwhile, the first random access parameter and the second random access parameter are transmitted by adopting a broadcast channel, so that a plurality of user equipment residing in a cell formed by the base station can receive conveniently without transmitting the user equipment one by one, thereby improving the transmission efficiency and reducing the power consumption of the base station.

Method example five:

step S110: configuring a second random access resource;

As shown in fig. 2, the method includes:

step S150: receiving a random access request sent by user equipment;

step S160: determining the type of the user equipment according to the random access resource sending the random access request; when the random access request is sent to be the random access resource of the first random access resource group, determining that the user equipment is the first type of user equipment; and when the random access request is sent to be the random access resource of the second random access resource group, determining the user equipment to be the second type of user equipment.

The user equipment receives corresponding random access parameters from a broadcast channel of a base station, and the first type of user equipment adopts a first random access resource group to send a random access request to the base station; the second type of user equipment sends a random access request to the base station by adopting a second random access resource group; after receiving the random access request, the base station firstly judges which random access resource group the random access resource capable of sending the random access request belongs to, so as to determine the type of the user equipment sending the random access request, and when the user equipment is allowed to randomly access, the base station determines that the downlink channel matched with the user equipment carries out downlink communication with the user equipment according to the equipment type of the user equipment, so that the user equipment can be ensured to receive the data sent by the base station, and effective communication between the base station and the user equipment is carried out.

Specifically, for example, the common user equipment adopts a first random access resource group for random access, and the base station adopts a physical downlink control channel and a physical downlink shared channel to communicate with the common user equipment; the eMTC user equipment adopts a second random access resource group for random access, and the base station adopts an enhanced physical downlink control channel and a physical downlink shared channel to communicate with the user equipment.

Method example six:

step S110: configuring a second random access resource;

The method further comprises the following steps:

counting the random access condition parameters of the second type of user equipment within a specified time;

and adjusting the random access resources included in the second random access resource group according to the random access state parameters.

The specified time can be a time configured in advance by the base station, and can also be a time received from an external device or a man-machine interaction interface. The specified time may have a time length of 10 seconds, 30 seconds, 15 seconds, or 1 minute or 2 minutes, etc.

The random access condition information may be a random access success rate or a failure rate, or may also be random access request numbers of the second type user equipment, which reflect the current random access condition information of the second type user equipment.

In this embodiment, in order to ensure that the random access success rate of the second type of user equipment meets a preset random access condition; the random access condition may be that a random access success rate of the second type of user equipment is greater than a preset probability, and when the random access success rate is lower than the preset probability, the number of the random access resources included in the second random access resource may be appropriately increased, specifically, the adjustment may include increasing the number of the second random access resources, specifically, the adjustment may include adopting more newly configured random access resources, or applying for more random access resources to an MME or other management equipment, and receiving an application response sent by an external device such as the MME to obtain more second random access resources and parameters corresponding to the second random access resources.

In this embodiment, all the first random access resources are generally used to form the first random access resource group, and all the second random access resources are used to form the second random access resource group, and random access status information of the second type of user equipment is collected and counted to dynamically adjust the number of the second random access resources, so as to ensure that effect parameters such as the success rate of random access of the second type of user equipment meet preset conditions.

Specifically, for example, the second random access resource group currently includes 4 second random access resources, and if it is found that the random access success rate of the second type of user equipment within the specified time is lower than the specified value, the second random access resources included in the second random access resource group are appropriately added, and for example, the second random access resources are dynamically applied for 4 second random access resources from devices such as an MME and the like.

The random access resources in the first random access resource group and the second random access resource group adjusted in this embodiment may be at least one of time-frequency resources and pilot codes used for random access.

Method embodiment seven:

step S110: configuring a second random access resource;

The method further comprises the following steps:

The adjusting the random access resources included in the second random access resource group according to the parameter of the random access condition includes:

and when the random access condition parameter indicates that the random access failure number of the second type of user equipment reaches a first threshold value, increasing the second random access resources included in the second random access resource group.

In this embodiment, the random access status information is a random access failure number of the second type of user equipment, and the first threshold is a preset value, or may be determined according to a total number of random accesses requested by the second user equipment within a specified time. When the first threshold is dynamically determined, a threshold determination ratio can be stored in the base station, and the threshold is obtained by calculating the product of the ratio and the total number of random accesses in a specified time according to a proportional function relationship.

In addition, in a specific implementation, the random access status information may also be a ratio between the random access failure number of the second type of user equipment and the total random access number within a specified time, and the ratio is compared with a ratio threshold to determine whether to increase the random access resources in the second random access resource group.

The random access condition information may also be directly a probability of random access failure of the second type of user equipment within a specified time.

When the second random access resources are all used in the second random access resource group, the increase of the random access resources in the second access resource group is realized by directly increasing the second random access resources, and the method has the advantage of small influence on the first random access resource group and the first random access resource due to simple configuration.

The eighth embodiment of the method:

step S110: configuring a second random access resource;

The method further comprises the following steps:

As a further improvement of this embodiment or a further limitation of the above method embodiment, the adjusting, according to the parameter of the random access condition, the random access resources included in the second set of random access resources includes:

and when the random access condition parameter indicates that the random access failure number of the second type of user equipment is lower than a second threshold value, reducing the random access resources of the second random access resource group.

The second threshold may be not greater than the first threshold, preferably the second threshold is less than the first threshold. When the second random access resources are all used for a second random access resource group, reducing the random access resources of the second random access resource group can be achieved by reducing the second random access resources, specifically, for example, releasing part of the second random access resources, and notifying information of the released part of the second random access resources to base station upper-layer equipment such as an MME, so that the base station upper-layer equipment such as the MME can conveniently and dynamically schedule the released second random access resources according to the needs of a current network, thereby improving the utilization rate of the random access resources and achieving the optimal setting of the random access resources.

By using the grouping unit 120 described in this embodiment to group the random access resources, the change of the random access resources of the general user equipment can be reduced as much as possible, and thus the information processing amount is small when grouping is performed inside the base station.

The sending unit 140 is configured to send the first random access parameter to the first class of user equipment on a first broadcast channel; sending the second random access parameter to the second type of user equipment by using a second broadcast channel; the first broadcast channel is different from the second broadcast channel.

In the embodiment, in order to facilitate different user equipments to receive the first random access parameter and the second random access parameter, different broadcast channels corresponding to the first type of user equipment and the second type of user equipment are respectively adopted to transmit the first random access parameter and the second random access parameter, and the broadcast channels are adopted to transmit, so that 1 base station transmits information to a plurality of base stations, and thus, the transmission efficiency can be improved and the power consumption of the base stations can be reduced.

In a specific implementation, the sending unit 140 may also send the first random access parameter and the second random access parameter by using the same broadcast channel, but send the distinguishing identifier when sending the first random access parameter; the user equipment selects the random access resource group to be accessed for random access according to the distinguishing identification.

As shown in fig. 4, the base station further includes:

a receiving unit 150, configured to receive a random access request sent by a user equipment;

a determining unit 160, configured to determine a type of the ue according to a random access resource that sends the random access request; when the random access request is sent to be the random access resource of the first random access resource group, determining that the user equipment is the first type of user equipment; and when the random access request is sent to be the random access resource of the second random access resource group, determining the user equipment to be the second type of user equipment.

The specific structure of the receiving unit 150 may also include a communication interface, such as a receiving antenna; the receive antenna and the transmit antenna may correspond to the same physical antenna or antenna array having both transmit and receive capabilities.

The determining unit 160 may be similar in structure to the configuring unit 110, the grouping unit 120, and the obtaining unit 1320, and may also include a processor and a storage medium; and may be integrated with at least one of the grouping unit 120 and the obtaining unit 130 corresponding to the same processor. The specific structure of the processor can be referred to in the first embodiment of the apparatus, and will not be described in detail here.

Device example six:

The base station further comprises:

a statistic unit, configured to count random access status parameters of the second class of user equipment within a specified time;

and the grouping unit is further used for adjusting the random access resources included in the second random access resource group according to the random access state parameter.

The specific structure of the statistical unit at least comprises a storage medium and a counter or a processor with a counting function and the like; the storage medium is used for storing the random access condition information; the counter or the processor with technical function is used for counting the random access failure number or success number, failure rate or success rate and other information of the second type of user equipment.

The specific structure of the grouping unit may refer to the above device embodiment, and may dynamically adjust the random access resources included in the second random access resource group according to the parameter of the random access status; therefore, the optimal configuration of the random access resources can be realized, and the random access success rate of the second type of user equipment is ensured.

Device embodiment seven:

The base station further comprises:

The grouping unit 120 is specifically configured to increase the second random access resource included in the second random access resource group when the random access status parameter indicates that the random access failure number of the second type of user equipment reaches the first threshold.

The grouping unit 120 may include a comparator or a processor having a comparison function; the comparator and the processor with comparison function are used for comparison between the random access failure number and the first threshold. The specific content and the forming manner of the first threshold may refer to the corresponding method embodiment, and a detailed explanation is not provided in this embodiment.

In this embodiment, the grouping unit 120 specifically defines a structure for dynamically adjusting the second random access resource in the second random access resource group, and similarly has the advantages of simple implementation and simple structure.

In this embodiment, the grouping unit is further specifically configured to reduce the second random access resources included in the second random access resource group when the random access status parameter indicates that the number of random access failures of the second type of user equipment is lower than a second threshold.

The second threshold is generally not greater than the first threshold, and in this embodiment the second threshold is less than the first threshold. When the second random access resources are all used for the second random access resource group, the grouping unit 120 reduces the second random access resources of the second random access resource group, which are detailed in that the base station releases part of the second random access resources, and notifies information of the released part of the second random access resources to base station upper-layer equipment, such as an MME, so that the base station upper-layer equipment, such as the MME, can conveniently and dynamically schedule the released second random access resources according to the needs of the current network, thereby improving the utilization rate of the random access resources and realizing the optimal setting of the random access resources.

Two specific examples are provided below in connection with any of the embodiments described above: example one: the first step is as follows: the base station adopts the original mode for the common user, namely informs the common user equipment of the available random access resources through a system message 2SIB 2; and the random access resource is also used for random access at this moment; the random access resources include time-frequency resources. For eMTC users, the base station needs to inform the eMTC user of the available random access resources with another system message SIB for the eMTC user equipment, where the SIB and SIB2 may contain pilot code information and available time-frequency resource information. The random access resources for the ordinary user equipment and the eMTC user equipment form different random access resource groups. The time-frequency resources and/or pilot codes of the two random access resource groups are different. The pilot code information and the available random resource information are components of the first random access parameter and the second random access parameter in the above embodiments

The SIB for an eMTC user equipment may be notified to an eMTC user through a broadcast channel over 6 RBs of the center frequency of the base station-usable frequency band. The random access resources for the normal user equipment and the random access resources for the eMTC user equipment cannot overlap. The common ue may be given the existing random access resource (i.e., the first random access resource), and the eMTC ue may use the new random access resource (i.e., the second random access resource) to distinguish the user types. The second random access resource employed by the eMTC device may be at least one of adding a new pilot code and adding a new available time-frequency resource. While maintaining the advantage of the original random access resource for the ordinary user equipment, the ordinary user equipment does not need to be changed at all. Only the eMTC user equipment needs to resolve the new random access resource. Because the random access resources occupy the total uplink resources, multiple configurations can be preset for the random access resources of the eMTC user equipment, so that the configurations can be adjusted to dynamically adjust the random access resources available to the eMTC user equipment; and the base station can adopt the least random access available resource configuration for the eMTC user equipment at first, namely the configuration mode of the least PRACH resource available for the eMTC user equipment.

The second step is that: the user equipment receives a downlink signal sent by the base station, for example, after receiving a downlink SIB or SIB2, analyzes the SIB or SIB2 to determine an available random access resource, and randomly selects one available random access resource to send a random access request.

The third step: and the base station determines the user type according to the received random access request, the pilot frequency code used by the base station and the used time frequency resource. If the user equipment is the eMTC user equipment, the fourth step is carried out, and if the user equipment is the common user equipment, the fifth step is carried out.

The fourth step: the base station responds to the random access request through the EPDCCH and the PDSCH on the frequency domain occupied by the eMTC user equipment random access resources, and sends a response message RAR.

The fifth step: the response mode of the base station to the common user equipment is unchanged from that of the existing system, that is, the PDCCH and the PDSCH respond to the random access request of the common user equipment, and a response message RAR is sent.

And a sixth step: the user equipment checks RAR (random Access response) sent by the base station and carries out corresponding response (Msg 3). And the user equipment corresponding to the eMTC goes to the seventh step, and the user equipment goes to the eighth step for the common user.

The seventh step: the base station responds according to the Msg3 sent by the user equipment, responds through an EPDCCH and a PDSCH for the eMTC equipment in the same way, and responds through a PDCCH and a PDSCH for the common user equipment; counting the number of random access request failures of eMTC user equipment (the Msg3 carries a unique user identifier, and the user identifier in the Msg3 can be counted to determine the number of the random access request failures), wherein the number of the uplink access failures of the user is considered to be 0 if no random access request of the user equipment exists, and the random access request is adaptively adjusted according to the following criteria:

if the base station finds that the random access failure number of the eMTC user equipment is larger than or equal to a certain threshold (such as 20), the random access resources available for the eMTC user equipment are increased, and if the maximum configuration is reached, the random access resources are maintained. In this example, more second random access resources may be newly added and configured again, and the newly added and configured second random access resources are divided into second random access resource groups for random access of the second type of user equipment.

If the base station finds that the number of random access failures of the eMTC user equipment is less than a certain threshold (e.g., 5), the available random access resource resources of the eMTC user equipment may be reduced, and maintained if the minimum configuration has been reached. In this example, the number of the random access resources included in the second random access resource group may be reduced, so as to reduce the number of the second random access resources included in the second random access resource group. The reduced second random access resources may be used for random access by other base stations in order to improve the effective utilization of the random access resources.

Notifying all eMTC user equipment in the base station of the changed random access resource grouping information; i.e. sending the second random access resource parameter to the second user equipment.

The base station adjusts the configuration of available resources for random access resources in SIB2 of the general user equipment according to the prior art.

And repeating the steps, and the base station adaptively adjusts the random access resource configuration aiming at the eMTC user equipment.

Example two:

as shown in fig. 5, the method includes:

the base station is additionally configured with a second random access resource; wherein the base station has been configured with the first random access resource before that.

The base station random access resources are divided into a first random access resource group and a second random access resource group.

The base station acquires a first random access parameter corresponding to the first random access resource group and a second random access parameter corresponding to the second random access resource group.

The base station sends a first random access parameter to the first type of user equipment on a first broadcast channel and sends a second random access parameter on a second broadcast channel.

Receiving the first random access parameter from a first broadcast channel by the common user equipment; the eMTC user equipment receives the second random access parameter from a second broadcast channel.

The common user equipment sends a first type random access request to the base station by using random access resources in the first random access resource group; and the eMTC user equipment sends a second type random access request to the base station by using the random access resources in the second random access resource group.

And the base station receives and determines the random access resource group to which the random access resource sending the random access request belongs.

And when the random receiving request is sent by a random access resource in the first random access resource group, determining that the random access request is sent by the common user equipment, and sending a random access response to the common user equipment by adopting a physical downlink control channel and a physical downlink shared channel. And when the random receiving request is sent by a random access resource in the second random access resource group, determining that the random request is sent by eMTC user equipment, and sending a random access response to the common user equipment by adopting an enhanced physical downlink control channel and a physical downlink shared channel.
