Description

Paging method and radio network controller

Technical Field

The present application relates to the field of communications, and more particularly, to a method of paging and a radio network controller.

Background

In a mobile communication network, the voice service setup delay of a calling user equipment and a called user equipment is one of indexes which are very concerned by operators and terminal users, and the voice service setup delay mainly refers to a time difference between the initiation of a call request by the calling user equipment and the reception of ringing information by the calling user equipment.

With the development of data services, a large amount of LTE (long term evolution) systems are equipped with stations, and LTE carries data services due to high spectrum efficiency, while conventional voice services continue to be carried in Universal Mobile Telecommunications System (UMTS) or global system for mobile communications (GSM) systems. Since LTE does not carry circuit-switched (CS) voice services, when a user equipment in LTE makes a call, it will call-switch fallback (CSFB) to UMTS or GSM, and after the CS is finished, it starts a fast-return function to return to LTE to continue packet-switched (PS) services. Thus, the aim of reusing the existing UMTS or GSM network to provide the traditional voice service for the user equipment in the LTE network is achieved.

However, the current establishment flow of the voice service between the calling user equipment and the called user equipment is from the calling user equipment CSFB to the UMTS-core network-LTE paging-from the called user equipment CSFB to the UMTS, the information interaction of the establishment flow of the voice service between the calling user equipment and the called user equipment is serial transmission (that is, the transmission of one message must wait for the transmission of the last message), the voice service establishment delay is very long, and the service experience of the user is seriously affected.

Therefore, how to reduce the delay of the voice service between multiple systems becomes an urgent problem to be solved.

Disclosure of Invention

The paging method, the wireless network controller and the base station can realize pre-paging of voice service among multiple systems, thereby reducing time delay of the voice service.

In a first aspect, the present application provides a paging method, where the method is applied to a communication system including a radio network controller and M evolved base stations enbs, where the radio network controller is connected to the M enbs, M is an integer greater than or equal to 1, and the method includes: the wireless network controller receives a call request message from a calling subscriber, wherein the call request message comprises identification information of a called subscriber called by the calling subscriber; the wireless network controller matches the identification information of the called user in an identification information set, wherein any one identification information in the identification information set corresponds to a user under the wireless network controller; when target identification information matched with the identification information of the called user exists in the identification information set, the radio network controller determines N target eNBs in the M eNBs according to the target identification information, wherein N is an integer which is less than or equal to M and is greater than or equal to 1; the radio network controller sends paging messages to the N target enbs, so that the N target enbs initiate paging to the called subscriber.

In the above technical solution, the radio network controller first determines whether the called user is in its own service range, and when the called user is in the service range of the radio network controller, further determines a target eNB to be paged according to the identification information of the called user. Because the radio network controller is connected with the eNB, the network cable network controller can directly send the message to the eNB, and therefore the radio network controller can directly initiate paging to the target eNB after determining the target eNB without passing through core network equipment, so that pre-paging of voice service among multiple systems can be realized, and time delay of the voice service is reduced.

In a possible implementation manner, the identification information set further includes a long term evolution LTE cell corresponding to each identification information; the radio network controller determines the N target enbs from the M target enbs according to the target identity information, including: the wireless network controller determines K target LTE cells according to the target identification information and the identification information set, wherein K is an integer greater than or equal to 1; the radio network controller determines the N target enbs according to the K target LTE cells.

In the above technical solution, the radio network controller determines the target LTE cell according to the identification information of the called user and the corresponding relationship between each identification information in the identification information set in the radio network controller and the LTE cell, and further determines the target eNB according to the corresponding relationship between the LTE cell and the eNB. This solution is easy to implement.

In a possible implementation manner, the radio network controller is a radio network controller where the calling party is located or a neighboring radio network controller of the radio network controller where the calling party is located.

In a possible implementation manner, when the radio network controller is the radio network controller where the calling subscriber is located, the method further includes: the radio network controller receives an indication message indicating whether the calling subscriber is CSFB fallback via telephone switching.

In the above technical solution, the radio network controller determines whether the calling user passes through the CSFB according to the indication information, and further determines whether to execute the called user identification information matching and the determination procedure of the target eNB after the matching. Thus, unnecessary judgment processes can be reduced, and the time delay of the voice service is further reduced.

The technical scheme can reduce the probability of paging failure and improve the user experience.

In one possible implementation, the radio network controller updating the identification information set includes: when the calling subscriber passes through the CSFB, the radio network controller judges whether the identification information of the calling subscriber exists in the identification information set or not; when the identification information of the calling subscriber does not exist in the identification information set, the radio network controller adds the identification information of the calling subscriber in the identification information set. The technical scheme can reduce the probability of paging failure and improve the user experience.

In one possible implementation, the method further includes: and when the identification information matched with the identification information of the called user does not exist in the identification information set, the wireless network controller forwards the request message to an adjacent wireless network controller of the wireless network controller.

Detailed Description

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

The technical scheme of the embodiment of the application can be applied to the calling process between the user equipment supporting the network architecture with a plurality of systems. The embodiment of the present application is described by taking LTE to carry data services and UMTS or GSM to carry traditional voice services as an example.

To facilitate understanding of aspects of embodiments of the present application, concepts related to the present application and related technologies will be described first.

In the CSFB, when the LTE-side user equipment initiates a CS service, a Mobility Management Entity (MME) instructs the user equipment to fall back to a target system CS network (e.g., UMTS, GSM, etc.), and then the CS service is initiated. Taking the CSFB procedure of the calling user as an example, the message interaction from the CSFB of the LTE side to the CS network of the target system is shown in fig. 1. This achieves the goal of reusing existing UMTS or GSM networks to provide traditional voice services to user equipment in LTE networks.

Fig. 2 is a schematic diagram of an existing paging procedure in a CSFB scenario. In fig. 2, a base station (NodeB, NB) is a UMTS base station, an eNB is an LTE base station, an RNC is a controller of the UMTS, and an MME and a Mobile Switching Center (MSC) are core network devices. Since there is no Radio Network Controller (RNC) in the LTE system, the calling user needs to send a paging message to the eNB through the MME when initiating paging. The current establishing process of the voice service of the calling user equipment and the called user equipment is from the calling user equipment CSFB to the UMTS-core network-LTE paging-from the called user equipment CSFB to the UMTS, the information interaction of the establishing process of the voice service of the calling user equipment and the called user equipment is serial transmission (namely, the transmission of one message must wait for the transmission of the last message), the voice service establishing delay is very long, and the service experience of a user is seriously influenced.

The application provides a paging method, which can realize pre-paging of voice service among multiple systems, thereby reducing the time delay of the voice service.

Fig. 3 is a schematic flow chart of a paging method according to an embodiment of the present application. The method shown in fig. 3 is applied to a communication system including a radio network controller and M evolved base stations eNB, the radio network controller is connected to the M eNB, M is an integer greater than or equal to 1, and the method in fig. 3 includes at least part of the following contents.

In 310, the radio network controller receives a call request message from a calling subscriber, the call request message including identification information of a called subscriber called by the calling subscriber.

In 320, the rnc matches the id information of the called user in an id information set, where any id information in the id information set corresponds to a user under the rnc.

In 330, when there is target identification information matching the identification information of the called user in the identification information set, the radio network controller determines N target enbs in the M evolved nodebs (enbs or enodebs) according to the target identification information, where N is an integer less than or equal to M and greater than or equal to 1.

In 340, the radio network controller sends paging messages to the N target enbs, so that the N target enbs initiate paging to the called user.

A Radio Network Controller (RNC) in the embodiment of the present application may be a radio network controller in a UMTS or GSM system, or may be other network devices with similar functions, and the embodiment of the present application is not limited in particular.

The base station in the embodiment of the present application may be an eNB in a Long Term Evolution (LTE) system, or may be other network devices with similar functions, which is not specifically limited in the embodiment of the present application.

The radio network controller and the eNB are provided with the interface, and the connection between the radio network controller and the M eNBs can be realized.

It should be understood that the radio network control and the eNB may be directly connected or may be connected through a relay device.

In some embodiments, the identification information of the called user is any identification information that can uniquely identify the called user. Correspondingly, the set of identification information in the radio network controller may be a set of identification information of all users within the service range of the radio network controller, and each identification information in the set of identification information may uniquely determine one user.

For example, the identification information may be an International Mobile Subscriber Identity (IMSI) of the user, a Temporary Mobile Subscriber Identity (TMSI) of the user, a Local Mobile Station Identity (LMSI) of the user, a Temporary Logical Link Identity (TLLI) of the user, and the like, and the embodiment of the present invention is not particularly limited.

Optionally, the identification information set in the radio network controller may be stored in the radio network controller in a table form, or may exist in any other form in the radio network controller, and this embodiment of the present application is not specifically limited.

And the wireless network controller matches the identification information of the called user in the identification information set. In some embodiments, the radio network controller may search for the identification information of the called user in the identification information set, and when the identification information of the called user is found in the identification information set, the matching is successful; and when the identification information of the called user is not found in the identification information set, the matching fails.

Optionally, the target identification information matched with the identification information of the called user may be identification information identical to the identification information of the called user, or may be identification information of different types uniquely determining the same user with the identification information of the called user, which is not specifically limited in the embodiment of the present application.

When target identification information matched with the identification information of the called user exists in the identification information set of the wireless network controller (namely, when the matching is successful), the wireless network controller determines N target eNBs in the M connected eNBs according to the target identification information. Optionally, the N target enbs include the eNB in which the called user is located.

There are many methods for the radio network controller to determine the N target enbs, and the embodiment of the present application is not particularly limited. In some embodiments, the set of identification information further includes an LTE cell corresponding to each identification information. And the radio network controller determines K target LTE cells according to the target identification information and the identification information set, and determines the N target eNBs according to the K target LTE cells. Specifically, the radio network controller determines K target LTE cells according to the target identification information and the corresponding relationship between the user and the LTE cell in the radio network controller, and the called user is in the K target LTE cells. And then the wireless network controller determines N target eNB according to the K target LTE cells and the corresponding relation between the LTE cells and the eNB. In other embodiments, the set of identification information further includes an eNB corresponding to each identification information. And the radio network controller determines the target eNB according to the target identification information and the corresponding relation between the identification information in the radio network controller and the eNB.

The user may move from the service area of one eNB to the service area of another eNB due to a change in location, and thus the set of identification information in the radio network controller needs to be updated continuously.

In some embodiments, when the radio network controller does not receive the ringing information from the called user within a preset time period, the radio network controller deletes the identification information of the called user in the identification information set. That is, in the case that the radio network controller fails to identify the called user as the called user due to the call timeout, the radio network controller considers that the called user is not in the service range, and thus deletes the identification information indicating the called user in the information set.

In other embodiments, the radio network controller receives an indication message indicating whether the calling subscriber is CSFB. When a calling subscriber passes through the CSFB, the radio network controller judges whether the identification information of the calling subscriber exists in the identification information set or not; and when the identification information of the calling user does not exist in the identification information set, the wireless network controller adds the identification information of the calling user in the identification information set. In other embodiments, when a user in the service range of the radio network controller is paged and the paged user passes through the CSFB, the radio network controller determines whether the identification information of the paged user exists in the identification information set; and when the identification information of the paged user does not exist in the identification information set, the radio network controller increases the identification information of the called user in the identification information set. That is, when there is a user CSFB to a UMTS cell or a GSM cell within the service range of the radio network controller, the radio network controller adds the identification information of the user to the identification information set.

Optionally, the calling party may carry the identification information of the calling party in the call request message, may also carry the identification information of the calling party in the indication message, and may also carry the identification information of the calling party through any other interactive message or instruction with the radio network controller, which is not specifically limited in the embodiment of the present application. That is, the radio network controller may obtain the identification information of the calling party through a call request message, an indication message, or any other interactive message or instruction with the calling party.

Optionally, when a user in the service range of the radio network controller is paged and the paged user passes through the CSFB, the radio network controller may obtain the identification information of the paged user through an indication message, a paging message sent by other network devices, and the like, which is not specifically limited in the embodiment of the present application.

In other embodiments, the set of identification information of the radio network controller may also be configured for it by the core network device. At this time, the radio network controller updates the identification information set to receive the configuration message sent by the core network device in real time or periodically.

The identification information set in the embodiment of the present application may be expanded on the basis of the neighboring cell relationship configuration of the radio network controller (that is, the identification information of the user is correspondingly added in the neighboring cell relationship configuration), or may be a new information set independent of the neighboring cell relationship configuration.

It should be understood that the various corresponding relationships related to the embodiments of the present application may be respectively independent corresponding relationships (for example, the corresponding relationship between the user identification information and the LTE cell is stored in the radio network controller as one data set, and the corresponding relationship between the LTE cell and the eNB is stored in the radio network controller as another data set), or may be different corresponding relationships existing in one data set, and the embodiments of the present application are not particularly limited.

In some embodiments, when there is no identification information in the identification information set that matches the identification information of the called user, the radio network controller pages the called user according to the paging procedure in the prior art (i.e., initiating paging via the core network).

In other embodiments, the radio network controller may also attempt to forward the call request message to a neighboring radio network controller of the radio network controller, and the neighboring radio network controller initiates the pre-paging to the called subscriber. Optionally, the number of times forwarding is supported may be configured. For example, the number of times of forwarding support is configured to be 1, that is, after the radio network controller forwards the call request message to the neighboring radio network controller, the neighboring radio network controller cannot forward the call request message, and the radio network controller or the neighboring radio network controller pages the called user according to the paging procedure in the prior art (that is, paging is initiated via the core network).

It should be understood that the neighboring radio network controller of the embodiment of the present application may be a radio network controller having an adjacency relation with the radio network controller.

The method for paging according to the embodiment of the present application is described in detail below with reference to specific examples.

Fig. 4 is a comparison diagram of a paging procedure of an embodiment of the present application and an existing paging procedure. In fig. 4, the flow from the radio network controller to the called user is shown, the solid line is the paging flow of the embodiment of the present application, and the dotted line is the existing paging flow. The base station (NodeB, NB) is a UMTS base station, the eNB is an LTE base station, the RNC is a UMTS controller, and the MME and a Mobile Switching Center (MSC) are core network devices.

As shown in fig. 4, after the CSFB of the calling subscriber and after UMTS, a call request message is sent to the RNC, and the RNC sends a paging message to the eNB of LTE in advance.

Since the RNC may be connected to multiple enbs, the RNC needs to know to which enbs to send the paging message. Therefore, before the RNC sends the paging message to the eNB, the LTE cell where the user is located is recorded through the CSFB instruction and the neighbor cell relation configuration in the embodiment of the present application.

The first message sent by the user to the RNC of the UMTS carries a CSFB indication which may indicate whether the user is CSFB or not.

And when the CSFB indicates that the user passes through the CSFB, the RNC records the identification information of the user under the corresponding LTE cell. Because the LTE cell neighboring cell relation of the UMTS cell is configured in the RNC, as shown in table 1, the user can only perform CSFB from the corresponding neighboring cell relation (for example, the user in the neighboring cell 1 range can only perform CSFB from the neighboring cell 1CSFB to the cell 1 of the UMTS), so that the RNC can record it, and obtain table 2. The identification information of the user is added to table 2 with respect to table 1.

It should be understood that the above-described process may be performed continuously when there are users who make call requests or are paged continuously within the service range of the RNC.

TABLE 1

TABLE 2

When the calling user calls the called user, the following paging flow of the RNC is triggered.

Step 1, RNC receives the calling request message sent by calling user.

And step 2, checking the identification information of the called user in the call request message by the RNC in the table 1, and checking the LTE cell where the called user is located.

Step 3, if the called user can be found in the LTE cell, determining a target LTE cell, further determining a target eNB according to the target LTE cell, and turning to step 3; and if the called user can not be found in the LTE cell, the existing flow is adopted for paging. For example, the called user is user 1, and the RNC can find the user in table 1, and then it is determined that the neighboring cell 1-3 is the target LTE cell, and further it is determined that the eNB corresponding to the neighboring cell 1-3 is the target eNB.

And step 4, the RNC sends a paging message to the target eNB, and the target eNB can initiate paging to a called user after receiving the paging message sent by the RNC. Thus, the target eNB directly initiates paging to the called user without waiting for the paging message of the core network.
