Description

Method and device for transmitting signaling, transmitting data and establishing GTP tunnel

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for transmitting signaling, transmitting data, and establishing a GTP tunnel.

Background technique

In the LTE (Long Term Evolution) system, the transmission of data is dependent on the scheduling of the base station. In the uplink, data is sent by the UE (User Equipment) to the base station. The base station cannot predict whether the UE has data to send. Therefore, the protocol is designed to report the UE: The UE sends an SR (Scheduling Request) to notify the base station that there is data in the uplink buffer. The base station detects the SR and then performs the UE on the UE. Scheduling and allocating a small amount of air interface resources; the UE reports a BSR (Buffer Status Report) to the base station to notify the base station of how much data to transmit; and after receiving the BSR, the base station performs the data according to the amount of data reported by the UE. The allocation of the corresponding uplink resources.

However, there are many different types of services in the LTE system, such as voice calls, video phones, online games, ftp (File Transfer Protocol) downloads, streaming media, etc. When the network is congested/loaded, the base station is Different services may have different processing priorities. Because the existing SR and BSR reporting mechanisms cannot distinguish the services, the base station cannot identify which uplink services are pending in the UE, and the corresponding priority processing cannot be performed. Taking the voice service as an example, before the voice service is transmitted, the two parties need to establish a voice channel through SIP (Session Initiation Protocol) signaling, but because the SIP signaling is carried on the default bearer of QCI=5, In addition to the SIP signaling, the default bearer can also transmit other data services. Therefore, the base station cannot further distinguish services according to the SR or BSR reported by the UE, so that when the uplink resources of the base station are tight, the base station may not be scheduled in time. There are SIP signaling required to send the UE, resulting in delay or even failure of voice service establishment.

detailed description

The present invention will be further described in detail with reference to the accompanying drawings, in which FIG. One of ordinary skill in the art based on the embodiments in this application All other embodiments obtained without creative efforts are within the scope of the present application.

The present application will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , a method for reporting a BSR according to an embodiment of the present invention includes:

Step 100: The user equipment (UE) determines the data to be sent in the uplink buffer.

In step 101, the UE determines that the data to be sent includes the SIP (Session Initiation Protocol) signaling, and reports the first indication information in the process of reporting the BSR (Buffer Status Report) of the UE to the base station. The first indication information is used to indicate that SIP signaling is buffered in the uplink buffer of the UE.

The UE of the embodiment of the present invention includes but is not limited to a smart phone, a tablet computer, and a notebook. The base station of the embodiment of the present invention includes, but is not limited to, an eNB (evolved Node B, an evolved base station), a BS (base station), and the like.

The following takes a base station as an eNB as an example, and specifically describes the structure of the wireless communication system shown in FIG. 2 .

As shown in FIG. 2, the structure of a wireless communication system according to an embodiment of the present invention includes a UE (User Equipment) 1, an eNB 1, an S-GW (Serving Gate Way), and a P-GW (PDN Gate Way). , PDN gateway) 1, P-CSCF (Proxy-Call Session Control Function) 1, MME (Mobility Management Entity) 1, UE2, eNB2, SGW2, PGW2, P-CSCF2, MME2 .

It is assumed that UE1 needs to establish voice service communication to UE2, where UE1, eNB1, S-GW1, P-GW1, and P-CSCF1 are devices at the calling end, and UE2, eNB2, S-GW2, P-GW2, and P-CSCF2 are Called device.

In order to enable the eNB1 to identify that the data to be sent in the uplink buffer of the UE1 includes the SIP signaling, the uplink resource is preferentially allocated to the UE1 for the transmission of the SIP signaling. Referring to the method for reporting and receiving the BSR in the embodiment of the present invention shown in FIG. include:

Step 300: UE1 determines data to be sent in the uplink buffer.

Step 301: The UE1 sends an SR to the eNB1 through a PUCCH (Physical Uplink Control Channel).

Step 302: After receiving the SR, the eNB1 allocates an uplink resource UL grant to the UE1.

Step 303: Before the UE1 reports the BSR to the eNB1 by using the uplink resource allocated by the eNB1, the UE1 determines whether the SIP signaling is included in the data to be sent by using the application layer of the UE1. If yes, step 304 is performed; otherwise, step 309 is performed.

Step 304: The UE1 sends the second indication information to the MAC layer, where the second indication information is used to indicate that the SIP signaling is buffered in the uplink buffer of the UE1.

Step 305: The UE1 determines, according to the second indication information, that the first indication information needs to be reported in the process of reporting the BSR of the UE1 to the eNB1.

It should be noted that, in the process of reporting the BSR of the UE1 to the eNB1, the UE1 reports the first indication information. Specifically, the UE1 sends a MAC (Media Access Control) PDU (Protocol Data Unit) to the eNB1. The BSR is carried in a MAC PDU (including a MAC CE (Control Element), and the first indication information is carried in a MAC header included in the MAC header of the MAC PDU, and the MAC CE and the bearer carrying the BSR are carried. A MAC subheader indicating the information corresponds.

The MAC CE that carries the BSR is also called the BSR MAC CE. Specifically, when the BSR is a Short BSR, the MAC CE that carries the Short BSR is also called the Short BSR MAC CE. When the BSR is the Long BSR, the Long BSR is carried. MAC CE, also known as Long BSR MAC CE.

It should be noted that the first indication information may be identified by an LCID (logical channel identify) that is previously agreed by the eNB1 and the UE1. The LCID is used to indicate that the SIP signaling is buffered in the uplink buffer of the UE1.

As shown in FIG. 4, it is a schematic structural diagram of a MAC PDU, which includes a MAC header, a MAC CE, a MAC SDU (Service Data Unit), and a Padding. Taking the MAC CE1 bearer BSR as an example, if the data to be transmitted in the uplink buffer of the UE1 includes the SIP signaling, the LCID of the MAC subheader corresponding to the MAC CE1 is the LCID pre-agreed by the eNB1 and the UE1. The agreed LCID is used to indicate that the uplink buffer in UE1 is buffered. SIP signaling.

The pre-agreed LCID and the indication information of the corresponding LCID are stored in the UE1. For example, the Long BSR with SIP uses the reporting format of the existing Long BSR MAC CE to indicate that the UE has the SIP signaling to be sent. The LCID field in the corresponding MAC sub-header is set to 10101, and the Short BSR with SIP uses the reporting format of the existing short BSR MAC CE to indicate that the UE has SIP signaling to be sent, and the corresponding MAC sub- The LCID field in the header is set to 10100 to be identified, as shown in Table 1.

Table 1

It should be noted that the pre-agreed in Table 1 is used to indicate that SIP is buffered in the uplink buffer of UE1. The LCID of the signaling is two LCIDs that are optional from the existing reserved LCID, but are not limited to the above two LCIDs.

For example, when the UE1 determines that the SIP buffer is buffered in the uplink buffer and performs the reporting of the Long BSR with the SIP, it is assumed that the UE1 carries the BSR in the MAC CE1, and the MAC CE1 corresponds to a MAC subheader to the MAC CE1. For example, the UE1 encloses the 10101 in the LCID field of the MAC subheader1. After receiving the BSR reported by the UE1, the eNB1 obtains the value of the LCID field in the MAC subheader1, so that the UE1 cache can be learned. There is SIP signaling.

In step 306, the eNB1 receives the first indication information, where the first indication information is a logical channel identifier pre-agreed by the eNB1 and the UE1, and the logical channel identifier is used to indicate that the SIP buffer is buffered in the uplink buffer of the UE1.

In step 307, the eNB1 determines that the SIP signaling is buffered in the uplink buffer of the UE1 according to the logical channel identifier that is pre-agreed by the eNB1 and the UE1 to indicate that the voice buffer is buffered in the uplink buffer of the UE1.

Taking Long BSR with SIP as an example, the eNB parses the LCID field in the MAC subheader of the BSR. If the value of the field is 10101, the eNB can learn that the UE buffer is buffered with SIP signaling.

In step 308, the eNB1 preferentially allocates the uplink resource of the data to be sent to the UE1.

In step 309, the UE1 reports the BSR, where the BSR does not carry the first indication information.

In step 311, the eNB1 receives the BSR.

Step 312: The eNB1 determines, according to the BSR, that the SIP signaling is not buffered in the uplink buffer of the UE1.

In step 313, the eNB1 preferentially allocates an uplink resource to the UE corresponding to the BSR carrying the first indication information.

In order to enable the eNB1 to identify that the data to be transmitted in the uplink buffer of the UE1 includes the SIP signaling, the uplink resource is preferentially allocated to the UE1 for the transmission of the SIP signaling. Referring to the embodiment of the present invention shown in FIG. 5, another reporting and receiving BSR is provided. Methods, including:

In step 500, the MME1 determines that the UE1 supports the voice service according to the second indication information or the subscription information of the UE1 obtained from the HSS (Home Subscriber Server).

The second indication information is capability information of whether the UE1 supports the voice service reported by the base station to the MME.

Step 501: MME1 triggers eNB1 to allocate a dedicated logical channel for SIP signaling, where the dedicated logical channel is only used to transmit SIP signaling;

Step 502: The eNB1 sends the logical channel identifier corresponding to the logical channel and the logical channel group identifier corresponding to the logical channel identifier to the UE1, where the logical channel identifier is used to identify the logical channel for transmitting SIP signaling, and the logical channel group The logical channel group corresponding to the identifier includes only the logical channel, and the logical channel group identifier and the logical channel identifier are in one-to-one correspondence;

Step 503: UE1 determines data to be sent in the uplink buffer.

In step 504, the UE1 determines that the data to be sent includes the SIP signaling, and reports the first indication information in the process of reporting the BSR of the UE1 to the eNB1.

The first indication information is a logical channel group identifier that is sent by the eNB1 to the UE1. The logical channel group identifier is associated with one logical channel identifier, and the logical channel identifier is used for identifying the logical channel for transmitting only SIP signaling.

As shown in FIG. 6a and FIG. 6b, the specific format of the Short BSR MAC CE and the Long BSR MAC CE is respectively included, where the BSR MAC CE includes at least one LCG ID (Logical Channel Group IDentify) field and one The Buffer Size field is used to indicate a logical channel group identifier, and the Buffer Size field is used to indicate the total amount of data buffered on all logical channels included in the corresponding logical channel group.

Therefore, when only one logical channel is included in the logical channel group, and the logical channel is only used for transmitting SIP signaling, the amount of data carried by the Buffer Size field corresponding to the LCG ID is only the amount of buffered data of the SIP signaling to be sent.

Step 505, the eNB1 receives the BSR;

Step 506: The eNB1 determines that the data to be sent of the UE1 includes SIP signaling according to the logical channel group identifier corresponding to the logical channel identifier corresponding to the logical channel for transmitting the SIP signaling.

It should be noted that, as shown in FIG. 6a and FIG. 6b, the format of the BSR MAC CE includes at least one logical channel group identifier and one cache data amount. The format of the Long BSR MAC CE is shown in Figure 6a. The format of the Short BSR MAC CE is shown in Figure 6b.

In step 507, the eNB1 preferentially allocates corresponding uplink resources to the UE1 according to the buffered data amount of the SIP signaling corresponding to the identifier of the logical channel group.

When the called device UE2 is in the idle state, in order to enable the eNB2 to recognize that the UE2 needs to receive the voice service, and then preferentially schedule the UE2, refer to the method for transmitting the paging message according to the embodiment of the present invention shown in FIG. :

In step 700, the MME2 (Mobility Management Entity) determines that the called user equipment UE2 needs to receive the voice service, and generates a first paging message that carries the first indication information, where the first indication information is used to indicate the first The UE2 that pages the message to be paged needs to receive the voice service.

Step 701: The MME2 sends the first paging message to each eNB in the MME2 jurisdiction.

Step 702: The eNB receives the first paging message sent by the MME2.

Step 703: The eNB generates a second paging message according to the first indication information, where the second paging message carries the second indication information, where the second indication information is used to indicate that the UE2 needs to receive the voice service.

In step 704, the eNB sends a second paging message to the UE2.

Step 705: The UE2 receives a second paging message sent by the eNB for paging the UE2.

Step 706: The UE2 generates, according to the second indication information, a random access request that carries the third indication information, where the third indication information is used to indicate that the UE2 needs to receive the voice service.

Step 707: The UE2 sends a random access request to the eNB.

In step 708, the eNB receives the random access request sent by the UE2.

It should be noted that an implementation manner of carrying the first indication information in the first paging message may be that the user equipment UE needs to receive the voice service by adding an indication information to the paging message, for example, when the user equipment When the UE needs to receive the voice service, the first paging message is carried in the first paging message, and when the user equipment UE does not need to receive the voice service, the first paging message is not carried in the first paging message; An indication message appears in the first paging message only when the UE corresponding to the first paging message needs to receive the voice service, otherwise it does not appear. Can also pass the paging message A new indication information is added to indicate whether the user equipment UE needs to receive the voice service. For example, when the first indication information is 1, the user equipment UE needs to receive the voice service, and when the first indication information is 0, It indicates that the user equipment UE does not need to receive the voice service, that is, the first indication information is always present in the first paging message.

Another implementation manner of carrying the first indication information in the first paging message may be indicated by a DSCP field in the IP header, for example, if the 6-bit field is set to a specific value, the user equipment is represented. The UE needs to receive voice services.

The second paging message carries the second indication information, and the random access request carries the third indication information, and the first paging message carries the first indication information, and is not described here.

Step 709: The eNB determines that the random access request carries the third indication information.

Step 710: The eNB determines, according to the third indication information, that the UE2 needs to receive the voice service, and allows the UE2 to preferentially access.

When the called device UE2 is in the connected mode user equipment UE, in order to enable the eNB to determine that the UE2 needs to receive the SIP signaling, the UE2 can be preferentially scheduled, and the method for transmitting data according to the embodiment of the present invention shown in FIG.

Step 800: The network side device receives data including SIP signaling.

Step 801: The network side device transmits the data to the network side device P-GW/S-GW through a GTP (GPRS Tunneling Protocol) tunnel, and the FPI (Flow Priority Index) in the GTP header of the data The indexing field and/or the DSCP (Differentiated Services Code Point) field in the IP (Internet Protocol) header of the data carries a preset parameter, which is used to indicate the data received by the network side device. Includes SIP signaling.

For example, taking the DSCP field as an example, when the 6-bit field is set to a certain value, it indicates that the data received by the network side device includes SIP signaling. When carrying the preset parameters through the FPI field, it is similar to carrying the preset parameters through the DSCP field, and is no longer cumbersome here. Optionally, the network side device is a P-CSCF.

Step 802: The eNB receives the network side device by using a GTP tunnel established between the network side device S-GW and the network side device S-GW. Prepare the data sent by the S-GW;

Step 803: The eNB determines, according to the FPI field in the GTP header of the data and/or the preset parameter carried in the DSCP field in the IP header, that the data includes SIP signaling, where the parameter is used to indicate the network side device S-GW. The received data includes SIP signaling.

In step 804, the eNB preferentially schedules the UE2, and sends the data to the UE2.

When the called device UE2 is in the connected state, in order to enable the eNB to preferentially schedule the UE2, another method for transmitting data according to the embodiment of the present invention shown in FIG.

Step 900, the MME2 determines that the UE2 supports the voice service.

Specifically, the MME2 receives the indication information reported by the UE2, where the indication information is used to indicate that the UE2 supports the voice service, and determines that the UE2 supports the voice service.

Or the MME2 obtains the subscription information of the UE2 from the HSS (Home Subscriber Server), and determines that the UE2 supports the voice service.

In step 901, the MME2 controls to establish a GTP tunnel for separately transmitting SIP signaling between the S-GW2 and the eNB2 to which the UE2 belongs.

Step 902: The eNB2 receives the data sent by the S-GW by using a GTP tunnel that separately transmits the SIP signaling.

Step 903: The eNB2 determines, according to the identifier corresponding to the GTP tunnel that separately transmits the SIP signaling, that the received data is SIP signaling.

In step 904, eNB2 preferentially schedules UE2.
