Mobile communication method, mobile communication system and access entity
View Patent ↗An embodiment of the invention provides a communication system. The communication system includes a user equipment which is moving within a coverage of a first network and a second network and is configured to send a location update request to a third access entity of the second network; and the third access entity which is configured to receive the location update request from the user equipment, acquire information of a first access entity of the first network from the location update request and determine whether a predetermined condition is satisfied If the predetermined condition is not satisfied, the user equipment is paged through the first access entity, and if the predetermined condition is satisfied, the user equipment is not paged through the first access entity. As such, the situation that the UE is paged in an area where it is unlikely to appear can be avoided.
1. A method for mobile communication where a user equipment is moving within a coverage of a first network and a second network, wherein the user equipment is registered with both a first access entity of the first network and a second access entity of the second network, and a first association is established between the first access entity and the second access entity so that when the user equipment needs to be paged, the user equipment is paged in a first paging area administered by the first access entity and a second paging area administered by the second access entity according to the first association, and the method comprising:
receiving, by a user plane equipment, a first message from a third access entity of the second network, wherein the first message is used to inform the user plane equipment to implement one step of the group consisting of: (a) prohibiting data or a paging request from being sent to the first access entity, and (b) deleting a bearer of the first access entity;
wherein, the first message is sent by the third access entity if a predetermined condition is satisfied, the predetermined condition comprises one or more of the following:
(i) a distance between an area where the user equipment is currently located and the first paging area administered by the first access entity exceeds a predetermined threshold;
(ii) the third access entity cannot be associated with the first access entity; and
(iii) a speed of the user equipment in a current access entity system is lower than a threshold.
2. The method of claim 1 , wherein the user plane equipment is one of the group consisting of (a) a serving gateway, and (b) a General Packet Radio Service (GPRS) gateway support node.
3. A user plane equipment, when a user equipment moving within a coverage of a first network and a second network, wherein the user equipment registers with both a first access entity of the first network and a second access entity of the second network, a first association is established between the first access entity and the second access entity; when the user equipment needs to be paged, the user equipment is paged in a first paging area administered by the first access entity and a second paging area administered by the second access entity according to the first association, the user plane equipment comprising:
a receiver, configured to receive a first message from a third access entity of the second network;
a processor, configured to implement one step of the group consisting of: (a) prohibiting data or a paging request from being sent to the first access entity, and (b) deleting a bearer of the first access entity;
wherein, the first message is sent by the third access entity if a predetermined condition is satisfied, the predetermined condition comprises one or more of the following:
(i) a distance between an area where the user equipment is currently located and the first paging area administered by the first access entity exceeds a predetermined threshold;
(ii) the third access entity cannot be associated with the first access entity; and
(iii) a speed of the user equipment in a current access entity system is lower than a threshold.
4. The user plane equipment of claim 3 , wherein the user plane equipment is one of the group consisting of (a) a serving gateway and (b) a General Packet Radio Service (GPRS) gateway support node.
